Abstract

The invention discloses a semiconductor chilling plate and a manufacturing method thereof. The method comprises the steps that: a semiconductor refrigeration assembly is provided, the semiconductor refrigeration assembly comprises a first insulation heat conduction layer, a second insulation heat conduction layer and a semiconductor layer, the first insulation heat conduction layer and the second insulation heat conduction layer are oppositely arranged, the semiconductor layer is located between the first insulation heat conduction layer and the second insulation heat conduction layer and comprises a plurality of couple pairs, and the couple pairs are connected in series and electrically connected with wires; and the side, provided with the first insulation heat conduction layer, of the semiconductor refrigeration assembly is a cold end, and the side, provided with the second insulation heat conduction layer, of the semiconductor refrigeration assembly is a hot end. A packaging structure is formed, the packaging structure is enabled to cover the side wall of the semiconductor refrigeration assembly, the packaging structure and the first insulation heat conduction layer form a first groove, and the wire is enabled to penetrate through the packaging structure and extend to the outer side of the packaging structure so as to obtain the semiconductor refrigeration sheet. Therefore, the obtained semiconductor chilling plate can bear the pressure of more than 1000 PSI.

Description

technical field [0001] The invention relates to the technical field of refrigeration devices, in particular to a semiconductor refrigeration chip and a manufacturing method thereof. Background technique [0002] The semiconductor refrigeration chip is a new type of refrigerator that achieves refrigeration through the Peltier effect. When direct current passes through a galvanic couple made of two different semiconductor materials in series, heat can be absorbed and released at both ends of the galvanic couple to realize refrigeration. The semiconductor refrigeration chip has the functions of refrigeration, cooling, constant temperature, etc., and can realize point-by-point temperature control, and has the advantages of small size, no mechanical transmission parts, no noise, fast cooling and heating conversion, high reliability, long life, no environmental pollution, and can be It has the advantages of miniaturization, miniaturization, reciprocity of cooling and heating. ...
