Design and implement of the medical semiconductor cooler

Abstract

Recently, the combined application technology of temperature difference thermoelectric devices, temperature difference thermoelectric refrigeration and temperature difference power generation has made rapid progress. Compared with traditional cooling methods, the widespread use of temperature difference semiconductor cooler based on the Peltier effect in various aspects of small-scale cooling especially medical use, which has made it gain more and more attention. Based on this, a medical semiconductor cooling system is designed in this work. The hardware circuit is based on a single-chip microcomputer system, including several parts such as a temperature sensor measurement system, an LCD display system, and a semiconductor cooler system. The software design includes single-chip microcomputer control program design, temperature acquisition subprogram design, and display subprogram design, then the cooling efficiency of semiconductor cooler and the refrigeration-box was measured, finally it completed and realized the design and temperature control of medical semiconductor cooler.
