Double-temperature-control heating plate with cooling function

The utility model discloses a double-temperature-control heating plate with a cooling function, and relates to the technical field of preparation methods of the double-temperature-control heating plate with the cooling function. The double-temperature-control heating disc with the cooling function comprises an aluminum alloy body, and a heating mechanism and a refrigerating mechanism are arranged in the aluminum alloy body. The heating and refrigerating mechanism comprises a heating pipe and a cooling pipe which are arranged in the aluminum alloy body, and the end of the heating pipe and the end of the cooling pipe extend to the top of the aluminum alloy body. And a first thermocouple and a second thermocouple are respectively arranged in the aluminum alloy main body. The structural design of the inner and outer ring thermocouples ensures that heat generated by the heating pipe is uniform and reliable, meanwhile, the aluminum alloy disc body is heated through heat conduction, the temperature of a control poin
