Special thermoelectric coolers

 

 

The special thermoelectric coolers sed in cases, making special requirements towards TEC's properties and construction.

 

Examples of special operational conditions:

- high vacuum (< 10-6)

- large mechanical loads (peak acceleration up to 1500 g)

special requirements towards TECs characteristics:

-  TEC height lower than 1,5 mm

- high cooling rate > 10 K/sec,

- high cooling power density  >20 W/sm2 , etc.

 

For the mentioned cases Kryotherm company offers a special list of thermoelectric coolers.

The mentioned technologies are used to produce coolers for:

- space and other special techniques

- optoelectronics and telecommunications

- medicine

- scientific research.

Kryotherm produces the majority of TECs to fit these aims on special demands.

As an example, the table lists the characteristics of some of the special TECs.

 

Technological features:

During the production of these modules ceramics AIN is used with thermal conduction > 180 W/mK or superfine substrate materials Al2O3 (100%), special thermoelectric elements with low height and high mechanical solidity and thermal bridges with small intercell gaps and small contact heat resistance.

 

Versions of performance:

- substrate material plate material - ceramics AlN or Al2O3 (ВК-100)

- gold plating or  solder tinning

- assembly solder from 139°С to 232°С (max assembly temperature: from 95°С to 220°С)

- mounting on cold or heat radiator, body or cold block.
