Abstract

The invention provides a temperature control system and an optical console having the same temperature control system. The temperature control system comprises a refrigeration unit, a temperature controller and a switching power supply. The temperature controller controls the switching power supply to drive the refrigeration unit to carry out refrigeration or heating. The refrigeration unit comprises a copper heat radiation support plate, a first refrigeration sheet, a first heat insulation pad, an annular heat spacer, a temperature control copper block, a second refrigeration sheet, a second heat insulation pad and a heat radiation block. The two refrigeration sheets and the copper heat radiation support plate are used to cooperatively buffer temperature control, the conventional technical problem that the accumulated heat is high and the refrigeration is hard is solved, the temperature changing rate is greatly improved, the testing time is saved, the usage is convenient, and the low temperature refrigeration effect is good.

Description

technical field [0001] The invention relates to the field of semiconductor temperature control, in particular to a temperature control system and an optical console containing it. Background technique [0002] In the experimental testing stage of scientific research institutes and universities, it is often necessary to control the temperature of semiconductor devices (such as lasers and solar cells) in order to test their photoelectric characteristics under constant or variable temperature conditions, and then develop targeted improvements. [0003] Due to the development and improvement stage, in order to obtain better device performance, it is usually necessary to carefully change the composition of the combined material, temperature, humidity and pressure parameters. The result of changing and combining various parameters is a wide variety of samples to be tested. Moreover, the existing temperature control system changes temperature slowly (longer test cycle), which ult...
