The utility model provides an environmental test case temperature control system, refer to FIG. 1, environmental test case temperature control system is including combination box and power module, and the combination box comprises a plurality of temperature control unit, and temperature control unit includes that box, refrigeration module, auxiliary electric heating module and wind channel board constitute. The air duct plate is arranged on the inner side surface of the box body, and the refrigeration module is arranged on the outer side surface of the box body. The refrigerating module of the environmental test chamber consists of a semiconductor refrigerating sheet, a radiator and a heat radiating fan.
The main part of the refrigeration module, the semiconductor refrigeration piece can absorb heat and radiate under the condition of switching on direct current, the two ends of the semiconductor refrigeration piece can absorb heat and radiate heat respectively, one end is close to the inner space of the unit box body and is the inner side, and the other end is close to the outer surface of the unit box body and is the outer side. Meanwhile, the refrigerating module is also provided with 2 groups of radiators and cooling fans which are respectively arranged at the inner side and the outer side, the radiators and the cooling fans at the inner side are called inner side radiators and inner side fans, and correspondingly, the radiators and the cooling fans at the outer side are called outer side radiators and outer side fans. The inner side radiator and the heat radiation fan circulate the air inside and contact with the refrigeration guide vane through the air channel provided by the air channel plate. In addition, the inner radiator is also provided with an auxiliary electric heater which can perform auxiliary heating through electric heating during heating.
