Hollow polygon prism-shaped heat exchanger

Abstract

The hollow polygon prism-shaped heat exchanger comprises a polygon prism main body connected with a heat source, the polygon prism main body is provided with a refrigerant flow channel parallel to the axial direction of the polygon prism main body, and the refrigerant flow channel is filled with foam metal; the polygon prism body is further provided with an inlet allowing refrigerants to flow in and an outlet allowing the refrigerants to flow out, the refrigerants enter the refrigerant flow channel through the inlet, and the refrigerants in the refrigerant flow channel flow out of the refrigerant flow channel through the outlet after heat exchange between the refrigerants in the refrigerant flow channel and a heat source is completed. A through first air channel is formed in the middle of the polygon prism main body and is provided with an axial flow fan; the air guide cover is arranged outside the polygon prism body in a sleeving mode, and a second air channel communicated with the first air channel is formed between the outer wall of the polygon prism body and the inner wall of the air guide cover. According to the heat exchanger, the foam metal is filled in the refrigerant flow channel, the refrigerant is boiled and exchanges heat in the foam metal, meanwhile, the air guide cover and the axial flow fan are integrated, forced convection heat exchange is conducted, and the heat exchange efficiency of the heat exchanger is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of heat exchanger equipment, and in particular relates to a hollow polygonal prism heat exchanger. Background technique [0002] With the rapid development of electronic information and other fields, the calorific value of various equipment and components is increasing year by year, and the demand for heat dissipation is also increasing. At present, the common heat exchanger used to dissipate heat from sheet heat sources is a plate heat exchanger, in which water or other coolants flow through the plate, and the plate needs to be thickened when the refrigerant is used, so that the heat dissipation capacity of the heat exchanger per unit volume is limited. limit. [0003] Metal foam is a porous material with low density, large heat dissipation area and good thermal performance. Among them, the open-cell metal foam has a continuous three-dimensional porous structure through which fluid can flow. Filling the ...
