Cold Plate With Custom Tap Pattern:

AHP-1200CPV with custom tap pattern

TECA’s AHP-1200CPV Cold/Hot Plate is modified with a customer-specified tap pattern. This allows the end user to attach power devices directly to the plate, for thermal testing. The end user manufactures components for critical aerospace environments. Reliability is a top priority. One of the benefits of thermoelectric cooling technology is the low maintenance requirements and long service life. With the only moving part being the fan, the AHP-1200CPV can be expected to perform reliably for many years. Convenient features include a built in temperature controller, communications software, and the ability to switch from internal to external sensing. Please contact TECA for a quote on the AHP-1200CPV, or to discuss how we can modify it to meet your unique requirements.

Freeze Tape Casting

by

Freeze Tape Casting Manufacturer:

A materials science company specializes in creating foams with specific porosity for use in electric vehicles, batteries, thermal interface materials and ceramic-metal interfaces. Utilizing a TECA thermoelectric cold plate as a component within the freeze tape caster ensures the manufacturing process remains environmentally friendly. Peltier cold plates use no freon, coolants, or chemicals of any kind. In this example, the customer has slightly modified a commercially-available, off-the-shelf (COTS) TECA cold plate to reach the desired -10C set point.

BATTERY COOLING

R & D Battery Cooling:

In this example, the customer is using TECA’s AHP-1800CPV to keep a 60 pound lithium ion battery cool during R&D testing. This saves the customer the trouble of using a plate with pumped coolant to cool the battery, which was the original method.

The customer reports that upgrading to the TECA AHP-1800CPV “makes testing much easier”.

The AHP-1800CPV is the largest thermoelectric cold plate on the market with a plate surface area of 12.80 x 13.30 inches.  The large surface area and robust cooling power were ideal for this application.

PERFORMANCE TESTING

Performance Testing:

Customer needed to test low-temperature performance of inertial measuring devices.  In this application of low temperature thermoelectric cooling; the user is testing inertial measurement devices over a temperature range.

The devices as well as the TECA cascaded cooling assembly are subjected to various rotational and acceleration stimuli while device temperature is controlled.  The custom thermoelectric cold plate cascaded (Peltier cascade) was built up from a standard Model AHP-301CP cold plate.

The finished test fixture was able to function with a maximum rotation rate of 1700° per second and 50 g acceleration.  The rotation is evident in the photo. By using a standard product as the basis for the cooling system, higher costs associated with a custom solution were avoided.

VACUUM CHAMBER

Vacuum Chamber:

Some engineers at Lucent wanted to cool devices inside a vacuum chamber and they didn’t want to reinvent the wheel. TECA’s been making devices like that for decades. They had a load of 10 to 20 watts generated and wanted -40 °C with about 15 °C to 20 °C water available.

A Custom LHP-800CP / LHP-300CP cascade, controller and power supply were supplied for a reasonable cost in a reasonable time frame.

MEDICATION STORAGE

Keeping medication at optimal storage temperature is very important.

A customized AHP-1200CPV thermoelectric cold plate (Peltier cooling plate) with plate that has grooves with various diameters to accommodate vials of different sizes and lengths was a perfect solution for the customer. Another feature of this custom thermoelectric cooling unit (Peltier cold plate) is tamper proof temperature controller.

LABORATORY APPLICATION

Laboratory Application:

In March our customer said: “We are most likely going to soon order 1 of the AHP-301CPV.”

First though, can you please provide a quote on the manufacture of a top plate? We would like to fit:

  • 2 x 500 mL Schott bottles (the one I measured was 86mm diameter)
  • 2 x 250 mL Schott bottles (the one I measured was 68mm diameter)
  • 2 x 50 mL Schott bottles (the one I measured was 46mm diameter)

I’d guess that Schott do not make their bottles to too tight specifications, so we would need to allow some room for tolerances. What do you think? These could be arranged in any way that fit best and that minimized any top plate overhang over the cold plate beneath. We can foresee out-growing the 50 mL bottles, so ideally would like the ‘walls’ surrounding the 50 mL wells to be thick enough to later be drilled out so that the wells can accommodate 100 mL Schott bottles (the one I measured was 56mm diameter). The height of the top plate (i.e. depth of the wells) only need be about 70 mm. For the current application, we only need to chill to about 5 deg °C. Does the range we are interested in affect anything?

In May we shipped the custom “Beaker Block: and AHP-301CPV.

In this example of an AHP-1200CP application a box surrounds the cold plate area. Materials are set directly upon the cold plate and the lid is closed. The material is cooled and temperature controlled without the large air cooling refrigerator.

ELECTRONIC TEST STATION

Electronic Test Station:

This is how the TECA Model AHP-1800CPV got its start. An aerospace contractor was interested in a large cold plate for the testing of electronic components. At the time our largest standard cold plate was the AHP-1200CPV. The client requested a larger plate. We added an accessory plate which was 12×18 inches (pictured).

This solution worked well, and we followed it by designing three new products:
AHP-1800CPV, AHP-2700CPV, and the AHP-5400CPV. These products have larger plates, ideal for working with multiple components or larger sized DUTs.

At TECA, we listen to our customers’ needs and push the limits of our designs- this is how we innovate! https://www.thermoelectric.com/about-teca/

QUICK COOLING OF A LOAD FROM 100 °C

Quick Cooling of a load from 100 °C

A company specializing in hydrogen fuel cell technology required fast cooling of a fixture. The fixture is bonding multiple thin materials and can be heated up to 100 °C. The fixture needed to be cooled to the point where it could be handled by technicians—within a 5 minute time frame. Using two AHP-1200CP Cold Plates from TECA, the customer has created a system where a heat sink is cooled on one AHP-1200CP Cold Plate while a hot fixture is sandwiched between a second AHP-1200CP Cold Plate and a pre-cooled heat sink.

The customer reports being very happy with the TECA Cold Plates—the system is cooling in about 4 minutes!  The AHP-1200CP Cold Plate is an economical, easy to use product when maximum cooling is required, without a temperature controller. 120 VAC, 240 VAC and 24 VDC versions are available.
