Semiconductor refrigeration and heat dissipation device

Abstract

A semiconductor refrigeration and heat dissipation device is simple and reasonable in structural design, the heat dissipation function can be greatly improved while the temperature of the refrigeration area is well controlled, and a cold conduction sheet can be conveniently detached and replaced. The semiconductor refrigeration and heat dissipation device comprises a semiconductor refrigeration block, and a heat dissipation copper sheet, heat dissipation sheets and a heat dissipation draught fan are sequentially and fixedly arranged at the upper end of the semiconductor refrigeration block. Acold conduction copper block is fixedly arranged at the lower end of the semiconductor refrigeration block, a cold conduction sheet is arranged at the lower end of the cold conduction copper block, and the cold conduction copper block and the cold conduction sheet are in sliding connection through a sliding block and a T-shaped sliding groove in the bottom end of the sliding lock. The sliding block, a temperature detector and a temperature induction controller are fixedly arranged at the bottom end of the cold conduction copper block, and the temperature detector and the temperature inductioncontroller are located on the two sides of the sliding block correspondingly. A plurality of heat dissipation holes are evenly formed in the heat dissipation sheets.

Description

technical field [0001] The invention relates to the technical field of refrigeration and heat dissipation devices, in particular to a semiconductor refrigeration and heat dissipation device. Background technique [0002] Semiconductor refrigerators are widely used because of their fast action speed, long service life, no pollution to the environment and easy control. By adjusting the size of the working current, the cooling rate can be adjusted conveniently, and by switching the direction of the current, the refrigerator can be transformed from a cooling state to a heating working state. [0003] However, the cooling and heat dissipation function of semiconductor refrigerators commonly used in the market must be controlled within a certain range. When the temperature of the cooling area exceeds the rated range during the operation of the refrigerator, continuous cooling will cause the problem of low temperature in this area. Therefore, It is necessary to keep the temperatur...
