Manufacturing method of cooler

Abstract

The invention provides a manufacturing method of a cooler. The method includes the steps that one strut of each U-shaped heat conductive pipe is pressed on a boss; cooling fins are riveted to the other strut of each U-shaped heat conductive pipe one by one; a bottom board and the boss are preliminarily riveted and fixed and meanwhile the two ends of each strut with the corresponding boss are riveted and fixed to the cooling fins; the boss is riveted, so that the boss is flush with the bottom board; and finally the bottom board and the cooling fins are riveted and fixed. The riveting process is adopted for manufacturing the cooler, no electroplating or welding process is needed, the process is simple, production efficiency is improved, production cost is reduced, energy is saved, and environmental friendliness is achieved. Meanwhile, the heat conductive pipes are flattened and then embedded in the bottom board, one side of each heat conductive pipe can make direct contact with a heat source, the other side of each heat conductive pipe makes direct contact with the cooling fins, heat resistance of an aluminum board is reduced, the heat conductive performance is effectively improved, a cooling path is shortened, heat generated by the heat source can be rapidly conducted and dissipated out, the cooling effect is improved, and the service life of the heat source is effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of radiators, and in particular relates to a method for manufacturing a radiator. Background technique [0002] A traditional heat sink is usually composed of a heat pipe, a bottom plate and cooling fins. However, since the heat pipes, bottom plate and heat dissipation fins that make up the traditional radiator are welded together by solder paste welding process, in order to meet the welding process requirements, some parts must be electroplated before welding, such as: bottom plate, heat dissipation fins Chips must be nickel plated before soldering. In this way, not only the process is complicated, the production efficiency is low, and the cost is high, but also high-energy-consuming processes such as electroplating and welding are required, which seriously damages the environment. At the same time, due to the heat dissipation through the heat sink of this structure, the heat generated by the heat source ...
