[Thermoregulating devices for artificial circulation apparatus with thermoelectric elements].

The increase of the absolute capacity of temperature control devices used in extracorporeal blood circulation apparatus has necessitated the intensification of heat exchange and, as a consequence, the work of heat exchangers under anisothermal conditions. This concerns mainly thermoelectric temperature control devices. Calculations in the process of their design and, to a greater extent, the optimization of their parameters under the conditions of anisothermality in the soldered joints become far more complicated. The numerical analysis of such thermoelectric device with anisothermal soldered joints has demonstrated the possibility of its analytical optimization by assuming it to be a thermoelectric device working under the average effective values of temperature and the coefficients of electrical characteristics. The results thus obtained allow to considerably decrease labor consumption in designing the above-mentioned devices.
