Low Temperature, Low Price

Introducing TECA’s newest cold plate product, the AHP-301CAS:

What is a cascaded cold plate? It is a system of multiple layers- each cascade layer acts as a heat sink for the layer above it. This creates colder temperatures at the top layer, colder than what could be accomplished with a single cold plate. TECA has introduced a new product to its stable of cascaded cold plate systems. The AHP-301CAS is a two-stage cascade system and in a 25degC Ambient environment, the AHP-301CAS can reach as low as -35degC.

For even lower temperatures, TECA has long offered larger 2-stage and 3-stage cascaded systems. However, we recognized a need for a simpler, less expensive cascade solution. Some industrial and laboratory applications do not require as low as -76degC below delta-T for example (see model AHP-1200C31). Our standard single cold plates can reach a range of -10 to -15degC. The new AHP-301CAS is a ‘goldilocks’ cascade system; colder than usual but not more than is needed. The AHP-301CAS is priced 20% less than the next larger cascade and is half the price of our most powerful cascaded system.


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.
