Manufacturing method and structure of huffing plate

Abstract

The invention discloses a manufacturing method and structure of a huffing plate. After a first cover plate and a second cover plate are cut, a punching machine is adopted for punching the first coverplate to form a first concave portion, and the first concave portion comprises at least one outlet communicating with the edge of the first cover plate. The first cover plate and the second cover plate are assembled correspondingly after being subjected to screen print welding, and thus the first concave portion and the second cover plate are attached relatively, so that a heat dissipating main body is formed. A jig is used for fixing the first cover plate and the second cover plate which are assembled relatively, then the first cover plate and the second cover plate are placed in a high-temperature furnace for braze welding, and the first cover plate and the second cover plate are combined together to form the huffing plate. According to the method and the structure, the manufacturing technology of a traditional huffing type evaporator is changed, a multi-pass traditional working procedure is omitted, the manufacturing technology of the huffing plate is simplified, and the labor expense is saved.

Description

technical field [0001] The invention relates to the technical field of inflation evaporators, in particular to a manufacturing method and structure of an inflation plate. Background technique [0002] The current mobile devices, personal computers, servers, communication chassis, or other systems or devices have improved computing performance, and the heat generated by their internal computing units has also increased. Therefore, a cooling unit is relatively needed to assist in cooling. At present, Some companies in the market have used inflatable plates to replace traditional cooling fins. [0003] The existing blowing plate uses silk screen printing to emboss the path of the evaporation pipeline on the plate, and combines it with another plate without embossed pipeline. After the plate is cut, cleaned, silk screen, riveted, hot rolled, cold Rolling, annealing, high-pressure inflation, and punching processes make it a composite panel in an integrated form. [0004] Using ...

AI Technical Summary

Problems solved by technology

[0004] Using the traditional method to process the blown plate, the process is complicated, the process is long, the process is difficult, and high temperature annealing is performed many times, the surface flatness of the plate is poor after processing

Moreover, the traditional process relies on high-pressure gas inflation to form pipelines, and it is difficult to make the pipelines consistent

In addition, the traditional process needs to go through hot rolling, cold rolling, high temperature annealing and other processes. In this series of processes, the two plates will be combined with each other, so high temperature resistant graphite paste is required to be screen printed into the pipeline to ensure that the pipeline will not be bonded. However, the graphite paste is resistant to high temperature and adheres to the inner wall of one side of the board. The formed hot plate cannot be cleaned again. The graphite paste will become impurities in the subsequent application of the inflation board, affecting its performance.
