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.
体外血液循环设备中使用的温度控制装置绝对容量的增加，使得强化热交换成为必要，结果导致热交换器在非等温条件下工作。这主要涉及热电温度控制装置。在其设计过程中的计算，以及在更大程度上在焊接接头非等温条件下对其参数进行优化，变得更加复杂。对这种具有非等温焊接接头的热电装置进行数值分析表明，通过将其假定为在温度和电气特性系数的平均有效值下工作的热电装置，可以对其进行解析优化。由此获得的结果能够大幅减少设计上述装置时的人力消耗。
