Temperature of the Surface vs Temperature of the Heater Conductors

When conducting your thermal testing, it is important to know that there is a difference between the temperature of the mounting surface versus the temperature of the conductors inside the heater itself.

EPEC

For example, if you are mounting a heater onto an aluminum plate and you want the aluminum plate to reach, say, 300°F, you likely will have the heater power up higher than 300°F so that it doesn’t take a long time for the plate to warm up. (The more extra power you use, the faster it will warm up.) Eventually, the heater and the plate stabilize at generally the same temperature, whether you control the heater or not. During this temp rise cycle, if you measure the aluminum plate and it says 300°, the conductors within the heater may be, for example, 350° because the heat not only goes into the aluminum plate, the heat also dissipates out the other side of the heater. If the heater is mounted ‘open face’ and is exposed to the air on the non-mounting surface side, that extra heat dissipates into the surrounding air.

However, air is not a great conductor – not nearly as conductive as the mounted surface side where the heat transfers into the mounting plate quickly due to its direct contact with the plate. Instead, the heat on the air side doesn’t exit from the heater as fast, further driving up the temperature of the conductor strands themselves, while becoming a contributing factor to the heater overheating.

Notably, it is the temperature of the individual heater strands within the heater itself that defines the limit of the heater, not the temperature of the plate.

The breakdown of the heater occurs when the temperature of the internal bonding adhesives holding the heater layers together exceeds the bonding adhesive’s temperature limits – and they delaminate. Specifically, it is the internal bond layers on both sides of the conductor that experience the highest temperature exposure. The foil conductor strands don’t fail because they are metal and won’t melt at anywhere close to this temperature. The insulative films (Teflon, fiberglass, polyimide) have high melt points so they, too, remain in-tact and perform insulating function.

The delamination that occurs within the heater causes the heater strands to lose contact with the mounting surface, creating an air gap between the plate and the heater strand. The result is that the heater strands no longer conduct quickly into the aluminum plate and the heat within the heater starts to rise. The heat builds and eventually things overheat, the surrounding encasement becomes brittle, the foil itself changes its metallurgical properties, thermal expansion takes place, and the combination of all of this causes burnout.

In reality, the thermal limit of the heater can be determined using an alternative method, such as this approach used in evaluating TurboFlex Teflon Fiberglass heaters. The true survival temperature of Teflon heaters can be determined by performing the opposite scenario. Instead of the heaters being powered and driving the heat generation, the aluminum mounting surface was raised to 450° through other means. The heater was passive and not powered, thus taking that influence out of the equation. In this method, the heaters are exposed to an accurate temperature throughout the body of the heater, and the testing confirms survival (no mechanical delamination) to 450° and higher. This way we know that the conductive strands were not experiencing a higher temperature than what the apparatus indicates.

Can the Heater Handle Higher Watt Densities?

Space.com

In a general perspective, flexible heaters are commonly rated by watt density limits. Although this gives a decent indication, the watt density limit completely depends upon the customer’s application and if the product design is able to keep the heat within the heater below the bonding adhesive’s mechanical threshold. This will be due to factors that contribute to getting the heat out of the heater. Interestingly, we have successfully used heaters with more than 75 w/in² watt density – a remarkably high value. These heaters were compressed between plates and the assembly was driving thermal shock tests from -40° to +100°C. The watt density and wattage were high, but the heater itself never approached its thermal limit. Furthermore, since the heater was mechanically squeezed between two thick plates, there was not an opportunity for delamination to occur even if the adhesive broke down because the plates held the layers in-tact. The insulative properties of the film will remain whether the adhesive lost its adhesion characteristics or not.

So, although watt density limits provide a guideline, customers should perform thermal tests with their particular design/package to understand where the thermal limit is.

Silicone Rubber

Fabbay

Silicone Rubber heaters are typically rated higher than traditional polyimide heaters but they, too, can experience thermal failure due to overheating. The same issue exists where excess heat builds up within the internal layers of the heater.

This would be due to a couple factors:

  1.  Losing contact with the mounting surface.

The peel-and-stick adhesive pre-mounted on the back of the silicone rubber is just not as strong as PSAs that adhere foil heaters constructed of polyimide films. It’s likely that the weak link is not the adhesion to the plate , its adhesion of the PSA against the silicone rubber surface that lets loose. The SR just doesn’t provide as strong of bonding interface with its own mounting adhesive. This is why many SR heaters are pre-mounted against their mounting surface/plate at the heater manufacturer’s factory – where the uncured rubber heater is vulcanized to the plate rather than using a separate bonding adhesive to mount it.

Particularly evident when mounting onto a curved surface, the thickness of the silicone rubber introduces an inherent mechanical tension to want to return to its flat state. This essentially creates a continuous tensile force pulling itself off the curved surface – further contributing to the adhesion potential to delaminate off the plate throughout temperature swings.

2. The thermally insulative properties of the silicone rubber.

As mentioned earlier, conducting the heat from the heating element into the mounting surface is very important. Silicone rubber is not only much thicker than plastic films, (4X to 10X thicker), the SR material itself is significantly more thermally-insulative than these films. The result is that the heat can’t transfer as quickly, and therefore the element itself retains more heat. And similarly, on the opposite “open-face” side that is exposed to the air, the heat can’t dissipate into the surrounding air as quickly as well.

Countering this effect is that that rubber is a higher thermally-rated material than the bonding adhesives within a traditional polyimide heater.

Combined, these aspects are likely the root cause of over heating failures of Silicone Rubber heaters, resulting in the generation of hot spots within the heater which cause failure. This is independent of the likelihood that the silicone rubber heaters may have rugged, long lasting wire-based conductive strands within it.

Conclusion

Although heat generation is the functional purpose of flexible heaters, customers of flex heaters need to understand that the heaters can deliver a substantial amount of wattage/heat – much more than the heater itself can handle. They have little mass and are not designed to retain heat.

Yet in these high temperature applications, they can survive and can be highly reliable – provided the heat they generate is quickly pulled out of the heater and into the surroundings – through conduction.

Conducting Basic Thermal Testing to Get Started

Many product development engineers struggle with determining the wattage needed in a heater in order to obtain the desired thermal result of their product design. They often have a good understanding of what they require their product to do (warm a plate to certain temperature in a certain amount of time, for instance), but translating that into a specific wattage in a flexible heater is more difficult.

The engineer can attempt to roughly calculate, and possibly even digitally simulate, the thermal requirements. However, usually the engineer that is responsible for the overall package design isn’t routinely conducting thermal analysis and thermal engineering so this area isn’t in the comfort zone for the engineer. The engineer can also utilize the TurboFlex’s Wattage Estimation Tool to help zero in on the wattage needed in the heater.

But one of the easiest and most accurate approaches is to conduct some basic thermal testing using actual components in order to gain confidence in the heater wattage.

Details

A common application for a flexible heater is to warm a mounting surface, such as an aluminum plate. To perform the basic testing to get started, the engineer should obtain the following:

  1.  The plate (or an actual unit desired to heat) or something with an equivalent mass.
  2.  A variable DC power supply that is capable of at least 10 amps and can deliver up to 24 volts DC. An example is this XPower 301D model.

3.  Thermal couple(s) and a Digital Thermometer.

4. Several flexible heaters of a size similar to what is needed to mate with the mounting plate. There are a variety of standard heater sizes available that may be suitable.  Plan to purchase 2-3 heaters to have back-ups and testing.

However, you need to purchase a heater with a specific wattage because that is how the heaters are identified.  The wattage rating of the heater will be stated against a defined voltage by the manufacturer.  For instance, a 100-watt heater would be specified in conjunction with a defined voltage, such as ‘12 volts.

It’s probable that a standard heater with the desired wattage is available in the preferred shape/size, but the rated voltage for that heater will be different than what is planned to be utilized in the product design.  This will not be an issue, provided the voltage is somewhat in the middle of the DC power supply range.

For example, a predicted target heater may be an 8” X 8” heater operating at 120 volts and delivering around 100 watts.  But maybe an 8” X 8” heater with these characteristics is not available.  However, a 6” X 6” 100 watt heater rated at 12 volts is available.  For this first stage of evaluation, this is fine.

The calculated resistance per Ohms Law of this 6 X 6 heater is 1.44 ohms but heater resistance may not be exact so it would be valuable to verify the actual resistance using an ohm meter.

Note:  Flexible heaters can operate in a wide variety of voltages.  Just because it states it is a 24-volt heater doesn’t mean it only runs at 24 Volts.  It means that if 24 volts is applied to this heater, it will deliver the rated wattage.   But if less or more voltage is applied, the heater will still operate, but the output wattage will change accordingly.  Of course, applying too high of voltage will burn out the heater or it may come apart because it just can’t handle the temperature spike.

Note:  A flexible heater will operate on either AC or DC.

Procedure

Identify or determine three things (roughly).

  1. The coldest temperature the unit will be exposed to during its expected use.
  2. The desired maximum temperature that the unit is to reach.
  3. How fast the unit must go from the coldest to the maximum temperature.

Install the heater onto the plate and hook up the unit to the DC power supply.  But instead of starting out using the heater at its rating level of 100Watts@12 Volts, start with something less since it is uncertain what is needed for thermal performance.  Plan to power it up at 9 Volts for instance.  Knowing the resistance of the heater is 1.44, using Ohms Law, this heater will deliver 56.25 Watts (Voltage Squared / Resistance) at 9 volts instead of its 100 Watts at 12 volts.

With the plate at a controlled temperature and with thermocouples mounted onto the plate or device, power up the unit and record what takes place.  Record the thermal readings in reasonable time increments and keep doing so until relatively stable temperatures being achieved.  This indicates that the power going into the system can no longer heat-up the product above what is being lost.

• Determine the peak temperature you desired was reached using the 9 Volts.
• Determine if the plate temperature rose fast enough.
• Plot the datapoints on a graph to establish a thermal rise curve so you can visually see the data.

Now, adjust and repeat this process but increase (or decrease) the voltage to arrive at the desired results. Keep in mind that the goal is to arrive at the defined wattage of the heater. This test is not to implement a specific thermal pattern which likely includes some level of thermal control devices to alter the curve/pattern.

Ideally, use environmental conditions that replicate the end use of the new product, however that is not necessary.

Perform many variations in voltage and thermal rise curves to confidently identify the wattage the heater needs to deliver to meet the product needs – regardless of the voltage used. For the example above, the testing may have determined that the thermal results were achieved when the 1.66 ohm heater operated 14.5 volts. Using ohms law once again, the result is 146 watts (V2/R).

Note: It is also advisable to push one of the extra heaters to its limits with over voltage levels. Plan to destroy a heater so that this knowledge is plugged into the reservoir of thermal performance in the product design.

Once a wattage level is determined, a custom heater can now be ordered. Specify a 146 Watt heater – but also specify that the heater is to deliver that wattage at the voltage planned for the product, and with the size/shape desired for the product design. In this example, order an 8” X 8” 146W/120 Volt heater.

Shown is an example of a 2” X 6” 1.8 ohm test heater mounted onto a 1/8” thick aluminum plate.

Conclusion

This simple procedure enables an engineer to zero-in on the wattage requirement needed for a new product design when the engineer may not have a good understanding of the thermal output a heater will deliver.  This approach also allows an engineer to utilize a low cost ‘standard’ heater as a test vehicle without purchasing a high cost, custom heater until the engineer knows exactly what is needed for both size and wattage.[/vc_column_text][/vc_column][/vc_row]

Heated Seats Outside: See How We Heated the Seats of This Outdoor Theatre

Background:

A customer who was building a 200-seat outdoor theater in Canada wanted to have heated seats to account for the city’s low temperatures of 20°F / -7°C. After the customer had defined the seats, we performed all of the thermal and mechanical engineering analysis to arrive at a flex heater solution. The resulting heaters could be retro-fitted into existing seats, giving two temperature setting options for optimal comfort even on cold days.

Application Information:

Due to the rugged outdoor environment from extreme cold to hot sun, the customer had decided to utilize an outdoor grade, plastic molded seat designed for punishing weather. This seat had a cavity under the base that permitted an attachment of a flexible heater to the slightly curved underside surface. The customer desired to have two levels of heating (plus OFF) that could be individually controlled by the user. Due to safety reasons, the heater was to operate at low voltage.

Through experience and experimentation, we determined that the desired temp setting of the seat in the outdoor environment would be approximately 90F for user comfort. The low heat setting would be about 20 degrees less.

Therefore we designed the heater to deliver approximately 70 degrees of thermal rise.

Due to cost constraints and the need for two temperature levels, the option of having single-seat temp sensing and control was not available. Therefore peak temperatures reached in high/low settings of each seat would be controlled and accomplished through input power management by the customer. Depending upon the outdoor temperature, the customer would adjust the voltage up/down slightly with a variable power system, typically adjusting between 22 and 24 volts.
