Machining method of radiator module

Abstract

The invention discloses a machining method of a radiator module. The machining method comprises the following steps of etching an aluminum-base copper-clad plate, and cutting the back face of the aluminum-base copper-clad plate to obtain a group of parallel fins; carrying out preservative treatment on the parallel fins; mounting cooling metal sheets which are the same in shapes on the parallel fins, so as to form the radiator module; carrying out solid packaging on the radiator module. The thickness of the aluminum-base copper-clad plate before cutting is a first set value, the distances from the top sides to the bottom sides of the parallel fins are not less than the first set value, and the thickness of the cut aluminum-base copper-clad plate is not less than a second set value after cutting; the cutting intervals of the parallel fins are not less than 2mm and not more than 10mm. The machining method of the radiator module further comprises the step of welding the radiator module to a PCB (printed circuit board) of an object to be cooled.

Description

technical field [0001] The invention belongs to the technical field of radiators, in particular to a processing method of a radiator module. Background technique [0002] The radiator manufacturing methods in the prior art include stretch forming and machining, these two methods. The stretch forming method has high efficiency and low cost, and it cannot process radiators with a fin height of more than 50 mm, a thickness of less than 0.4 mm, and a pitch of less than 4 mm, that is, there are restrictions on the size of the processed parts. Nowadays, many high-power components require radiators with a height of more than 50mm, a thickness of less than 0.4mm, and a spacing of less than 4mm. Since the stretch forming method cannot be formed, a machining method has been produced. There are also two machining methods, one is punch processing and the other is planer processing. Although these two methods can process the radiators with the above requirements, there are many disadva...

AI Technical Summary

Problems solved by technology

Although these two methods can process the radiators with the above requirements, there are many disadvantages as follows: one is low yield rate, the other is high requirements for equipment, fixtures and tools, which cannot be achieved by ordinary equipment; mass production

[0003] At the same time, due to the different structures and materials used in different applications, the heat dissipation effect cannot be accurately evaluated, which also brings problems to the production process.
