Abstract

The invention relates to a refrigeration structure. The refrigeration structure comprises a semiconductor refrigeration sheet, and the semiconductor refrigeration sheet comprises a PN galvanic coupleparticle layer, a cold surface and a hot surface; the cold surface and the hot surface are correspondingly arranged at the cold end and the hot end of the PN galvanic couple particle layer, and the PNgalvanic couple particle layer is provided with a positive electrode and a negative electrode; the hot end of the PN galvanic couple particle layer uses a heat conducting plate to form the hot surface of the semiconductor refrigeration sheet; and a refrigerant is contained in the heat conducting plate. By adopting the refrigeration structure, a middle ceramic plate and a heat conduction siliconegrease coating are eliminated at the hot end, heat transfer resistance is reduced, and heat conduction/heat dissipation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of heat dissipation or refrigeration, in particular to a refrigeration structure. Background technique [0002] The process of traditional heat pipe radiator is copper tube + pot copper powder + sintering + tank liquid + vacuum + sintering = complete heat pipe; after the heat pipe is completed, the pipe can be bent, flattened, and finally welded or welded with other heat sinks or heat pipes Riveting etc. The process is complex, and the bending affects the heat dissipation efficiency. [0003] Traditional heat pipe process: the heat pipe is directly welded or riveted to the heat sink. The heat-absorbing end of the heat pipe, that is, the heating area of ​​the evaporating end is affected by the bending process of the copper pipe, and cannot be completely fitted, resulting in a relatively low heat-absorbing and heat-conducting efficiency. [0004] The traditional process of semiconductor refrigeration chips:...
