摘　　要：电路板测试用温差电控温箱是一个既可致冷又可致热的精确控温箱。采用温差电致冷组件和薄膜加热片作为致冷致热的中心部件,用单片机进行精确控温。控温箱的控温范围为-40～+55℃,控温精度为±0.5℃,可以用于各种电子线路板的温度测试。详细叙述了其设计原理、结构和控温模式,同时给出了实验数据。Thermoelectric cooling-heating unit of circuit board for test is a compact warmer and cooler with an exact temperature control system. It used thermoelectric cooling modules for cooling and a thin film heater for heating, and adopted SCM for temperature control. The temperature control range was -40-＋55℃ ,the temperature control precision is ±0.5℃. The design principle, configuration, temperature-control mode were introduced and the test results of the thermoelectric cooling-heating unit detail were shown.
