Base vibration type semiconductor cold-hot cup

A base vibration type semiconductor cold-hot cup belongs to the technical field of electrical equipment and comprises a shell, an aluminum cup, an aluminum heat-transfer block, aluminum radiating fins, heat-preserving cotton, a semiconductor wafer, a radiator fan and a clump weight, wherein one surface of the semiconductor wafer is attached to the aluminum heat-transfer block and the other surface of the semiconductor wafer is attached to the aluminum radiating fins; the heat-preserving cotton is arranged in gaps among the aluminum heat-transfer block and the aluminum radiating fins; the radiator fan is arranged on the aluminum radiating fins; the shell is wrapped outside the aluminum cup, the aluminum heat-transfer block, the aluminum radiating fins, the heat-preserving cotton, the semiconductor wafer and the radiator fan; and the clump weight is arranged on one blade of the radiator fan. The base vibration type semiconductor cold-hot cup solves the problem that similar products on the market at present are not ideal in cooling speed, is made of metallic aluminum so as to be good in heat transfer effect and low in cost, is simple in structure, can achieve excellent cooling effectand heating effect only by electrifying the semiconductor wafer with a 12V direct-current power supply, is free of a refrigeration agent so as to achieve the aim of energy conservation and environment protection, can realize the vehicle-mounted function, and has better market prospect.
