Inlaying method for heat conduction pipe

Abstract

The invention relates to an inlaying method for a heat conduction pipe. The inlaying method comprises the steps that an inlaying groove is formed in a workpiece, and the width of an opening of the inlaying groove is smaller than the width of the portion, adjacent to the opening, of a groove body; the heat conduction pipe is inlaid into the inlaying groove; the top end of the heat conduction pipe is subjected to flare-in stamping for the first time, and the bottom end of the heat conduction pipe is pressed tightly to the bottom of the inlaying groove; the top end of the heat conduction pipe is subjected to flare-in stamping for the second time, and the two sides of the heat conduction pipe are pressed tightly to the side walls of the inlaying groove; and the top end of the heat conduction pipe is subjected to flare-in stamping for the third time, the top end of the heat conduction pipe is flattened, and the heat conduction pipe is fixed into the inlaying groove in a flare-in mode, wherein a third punch adopted for flare-in stamping for the third time is provided with a platform part. When the inlaying method for the heat conduction pipe is used for inlaying the heat conduction pipe, the heat conduction pipe can be fixed to the workpiece in a flare-in mode through the cold inlaying method, and the heat conduction pipe makes tight contact with the inlaying groove tightly, so that the working efficiency is improved, the machining cost is lowered, the bonding stability is enhanced, and the heat conduction effect is improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing heat dissipation devices, in particular to a heat pipe embedding method. Background technique [0002] Heat dissipation is something that most devices need to address. One of the solutions is to inlay heat pipes on the workpiece. For example, the more common method is to open an inlay groove on the workpiece, and then inlay heat pipes (based on factors such as cost, hardness, and heat dissipation rate, copper heat pipes are more common at present) in the mounting groove. [0003] The traditional method of inlaying heat pipes is: opening an inlay groove on the workpiece, applying glue in the inlay groove, then inserting the heat pipe into the inlay groove, and waiting for the glue to solidify. After the glue is solidified, welding processing is performed at the edge of the opening of the inlay groove, and the heat pipe and the edge of the inlay groove are welded together. The disadvantages...

AI Technical Summary

Problems solved by technology

[0004] 1. Glue bonding and welding processing are required, and the secondary processing complicates the process, increases the burden of processing costs and reduces work efficiency

[0005] 2. The combination stability of the heat pipe and the mosaic groove is related to the size and material of the glue and solder, and the combination stability is low

[0006] 3. Glue and solder are added between the heat pipe and the inlay groove, which reduces the heat conduction effect between the heat pipe and the workpiece
