Example Embodiment

[0027] It can be known from the background technology that the yield of aluminum alloy products needs to be improved. The reasons are:

[0028] In order to achieve good resistance to high temperature deformation, 6061 aluminum alloy products adopt complex water channel structure design. During the use of the 6061 aluminum alloy product, continuous cooling water flows into the water channel structure, which can take away a large amount of heat on the surface of the product.

[0029] Among them, the welding of 6061 aluminum alloy products usually adopts vacuum brazing, molten lead welding, intermediate layer connection welding and liquid phase diffusion welding. The 6061 aluminum alloy products formed by the above welding methods can easily cause deformation or even blockage of the water channel structure when the welding strength of the formed aluminum alloy products is high, resulting in insufficient water flow, affecting product heat dissipation, and easily causing the aluminum ...

Abstract

The invention provides a manufacturing method of an aluminum alloy product. The manufacturing method of the aluminum alloy product comprises the following steps: a first aluminum alloy plate and a second aluminum alloy plate are provided, wherein a surface to be welded of the first aluminum alloy plate is a first welded surface, and a surface to be welded of the second aluminum alloy plate is a second welded surface; the first welded surface is a plane, and a groove is formed in the second welded surface; or grooves are formed in the first welded surface and the second welded surface; the first welded surface and the second welded surface are oppositely arranged and bonded, and a water way structure, surrounded by the grooves, is formed between the first welded surface and the second welded surface to form an initial aluminum alloy product; the initial aluminum alloy product is filled in a cover; the cover is degassed to form a vacuum cover; then, a hot isostatic pressing process is performed on the initial aluminum alloy product; and the vacuum cover is removed to obtain the aluminum alloy product. As the hot isostatic pressing process is applied on the initial aluminum alloy product, the welding strength of the formed aluminum alloy product is improved, and meanwhile, deformation or even blockage of the water way structure is prevented.

Description

technical field [0001] The invention relates to the field of semiconductors, in particular to a method for manufacturing an aluminum alloy product. Background technique [0002] 6061 aluminum alloy is a high-quality aluminum alloy product produced by heat treatment and pre-stretching process. Excellent characteristics such as polishing, easy coloring film, excellent oxidation effect, etc., have been widely used in automatic mechanical parts, precision machining, mold manufacturing, electronics and precision instruments, etc. [0003] With the continuous upgrading of product technology, many 6061 aluminum alloy products adopt complex water channel structure design in order to achieve good high temperature deformation resistance. During the use of the 6061 aluminum alloy product, continuous cooling water flows into the water channel structure to take away a large amount of heat from the surface of the 6061 aluminum alloy product, so as to realize the long-lasting high-tempera...
