Manufacturing method of water-cooled plate

Abstract

The invention discloses a manufacturing method of a water-cooled plate. The manufacturing method comprises the following steps: step one, processing a groove in a substrate, wherein the groove comprises a plurality of linear sections and a plurality of semi-circular sections by which the linear sections communicate with one another, processing a water-cooled tube, bending the middle of the water-cooled tube according to the shape of the groove, and processing a plurality of pressing blocks for covering the linear sections, wherein each pressing block comprises an auxiliary section arranged onthe upper portion and a groove-shaped section arranged on the lower portion, each auxiliary section comprises a supporting portion and a ventilating portion, and the ventilating portions and the supporting portions are alternately arranged; step two, embedding the water-cooled tube into the groove; step three, placing the pressing blocks in the corresponding linear sections, attaching the groove-shaped sections to the surface of the water-cooled tube, and erecting the supporting portions to the two sides of the linear sections; and step four, fixedly connecting the substrate, the water-cooledtube and the pressing blocks by braze welding. The manufacturing method of the water-cooled plate has the beneficial effects that the yield of products is improved, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of water-cooling equipment manufacturing, and in particular relates to a method for manufacturing a water-cooling plate. Background technique [0002] With the development of society and the advancement of science and technology, the power electronics and information industries are also constantly developing and progressing. The integration and calorific value of heat sources have been greatly improved. The traditional air-cooling technology with large space requirements and poor heat transfer capacity has been far away This kind of problem can no longer be solved. The water cooling technology that was widely used in industries such as power transmission and distribution, coal, and medical treatment has gradually been applied to devices with high spatial integration such as servers, computers, and virtual machines. In the existing system, there are more and more cases of switching from air cooling to water cooling due...

AI Technical Summary

Problems solved by technology

The current water-cooled plate manufacturing method uses two aluminum plates to clamp S-shaped steel pipes in the middle and then brazes them. The welding area is small. The method of two aluminum plates sandwiching S-shaped steel pipes in the middle and then brazed will cause welding blind spots in some areas in the middle. , it is impossible to detect whether the welding is good, so that the heat transfer performance is deteriorated, the process is uncontrollable, the first pass rate of the product is low, and the production cost is high
