Problems solved by technology

This solution has two defects: one is high-temperature sintering, which requires more energy. For radiators with relatively large sizes, such as communication base station products, the energy consumption in the sintering process is very high, which will lead to a sharp increase in the cost of the radiator; two. It is the thermal conductivity of metal foam, which is much weaker than that of the metal body. For example, the thermal conductivity of aluminum is above 150W / m*K; while the thermal conductivity of aluminum foam is only about 30W / m*K

Embodiment 1

[0018] Such as figure 1 As shown, an air-cooled radiator adopting the present invention includes a radiator body (1), a heat-absorbing bottom plate (2), and the radiator body (1) contains at least two cooling fins (3), Open-cell foam metal (4) is filled between the cooling fins (3). The heat sink is extruded aluminum and has 10 cooling fins, the distance between the cooling fins is 11.14 mm, the porosity of the filled foam metal (4) is 80%, and the equivalent diameter is 1 mm. The original width is 13mm, and after compression, it is stuffed between the 11.4mm fins, a total of 9 pieces, and the compression ratio is 14.3%. After actual testing, the cold plate has a 30% increase in heat transfer performance after being filled with compressed metal foam copper.

Abstract

The present invention discloses a method for manufacturing an air-cooled radiator. The air-cooled radiator includes a radiator body. The radiator body includes at least two cooling fins. Foam metal is placed between the cooling fins, so that the radiating area is increased, and the heat exchange capability of a heat exchanger is enhanced.

Description

technical field [0001] The invention relates to a method for manufacturing an air-cooled radiator, in particular to a method for manufacturing a forced air-cooled radiator with an aluminum extruded or die-cast radiator as its main body. Background technique [0002] With the increase of the power of electronic devices, the heat flux density is getting higher and higher, and there are more and more devices with high power density such as servers and IGBTs. The heat dissipation requirements of forced air cooling are also getting higher and higher. In order to improve the heat dissipation capacity of forced air cooling, the current radiators have changed from traditional aluminum extruded and die-cast radiators to shoveled radiators and slotted radiators to further increase the density of the fins and reduce the spacing of the fins, thereby To achieve the purpose of increasing the heat dissipation area. However, these solutions greatly increase the cost of the product due to ...
