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
The present invention relates to the manufacture method of a kind of air-cooled radiator, particularly to a kind of with aluminium extruded or die casting radiator the manufacture method of the forced air cooling radiator as body.
Background technology
Along with the increase of electronic device power, heat flow density is increasing, and the equipment of the high power density such as server, IGBT gets more and more.The radiating requirements of forced air cooling is more and more higher.For improving the heat-sinking capability of forced air cooling, current radiator, from traditional aluminium extruded, die casting radiator, turns to teeth radiator, gear shaping radiator, to improve the density of fin further, reduces the spacing of fin, thus reach the purpose of increasing heat radiation area.But, these schemes, due to the restriction of technique, considerably increase the cost of product.
Patent CN200610105099.7 discloses a kind of metal foam radiator for electronic heater members.This patent " by any metal foam machine-shaping, and high temperature sintering is on heat sink ".The program has two defects: one is high temperature sintering, and the energy of needs is the most, and for the radiator that size is bigger, such as communication base station series products, the energy consumption of sintering process is the highest, and the cost of radiator can be caused to sharply increase；Two is the capacity of heat transmission of metal foam, compared with metal body weak a lot, the heat conductivity of such as aluminum is at more than 150W/m*K；And the heat conductivity of foamed aluminium only has about 30W/m*K.Therefore, when foam metal thickness is the highest (such as more than 30mm), with the temperature of fluid relatively, its radiating effect is very little for the foam metal temperature of its first half.
Summary of the invention
In order to solve above-mentioned deficiency of the prior art, the invention provides a kind of processing simple, the manufacture method of the air-cooled radiator of superior performance.
For achieving the above object, the present invention is by the following technical solutions:
A kind of air-cooled radiator, comprise radiator body (1), heat absorption base plate (2), described radiator body (1) at least contains two radiating fins (3), fills open cell foam metal (4) between radiating fin (3).
As preferably, radiator body (1) is die casting or Al squeezing material；
As preferably, the equivalent separation between adjacent heat radiation fin (3) is more than 1mm；
As preferably, the equivalent separation between adjacent heat radiation fin (3) is less than 100mm.
As preferably, foam metal (4) is with interference fit, is pressed in radiating fin (3).
As preferably, foam metal (4) can also be welded together with heat absorption base plate (2), at least one face of radiating fin (3) of radiator body (1) by welding.
As preferably, foam metal (4) and radiating fin (3), heat absorption base plate (2) contact surface on, scribble Heat Conduction Material or material be adhesively fixed；
As preferably, the approximate aperture of foam metal (4) is between 0.05 ~ 10mm.
As preferably, foam metal (4) is in one of them or the both direction that are perpendicular to flow direction, and its compression ratio is more than 0.5%, less than 50%.
