Detailed Description
The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As discussed in the background of the invention, conventional vapor chambers are typically made of pure copper or alloys. The alloy or pure copper material is adopted as the shell, which has the advantages of low contact thermal resistance of a heat source, but has the defects of insufficient overall strength and hardness, and is easy to cause various defects in the production and assembly processes, such as surface point damage, bending deformation, poor flatness and the like. When the soaking plate is used as a structural support member, impact resistance may be insufficient, strength may not be required, and the like.
In order to solve the technical problem, the invention provides a soaking plate made of a composite metal material, and referring to fig. 1, the soaking plate comprises an upper soaking plate cover 1 and a lower soaking plate cover 2 which are assembled together, a capillary structure 3 is arranged on the inner side of the upper soaking plate cover 1, and a support column is arranged on the inner side of the lower soaking plate cover 2. The soaking plate upper cover 1 and the soaking plate lower cover 2 are both formed by compounding at least two of metal materials and alloy materials.
In the present invention, the composition is different from an alloy, which means that two materials are tightly combined together to form a combined body through various feasible ways, including but not limited to rolling, spraying, high temperature sintering, and electroplating. Wherein spraying refers to spraying metal or alloy powder/particles onto another material to form a bond. Composite metallic materials include, but are not limited to, copper, titanium, and the like, and alloy materials include, but are not limited to, stainless steel, copper alloys, aluminum alloys, and the like.
By the composite mode, the advantages of two or more materials can be combined, so that the performances of the soaking plate in the aspects of strength, thermal conductivity, corrosion resistance and the like are improved. For example, copper is compounded with stainless steel by a rolling process and then processed into a soaking plate, thereby combining the characteristics of low thermal resistance of the copper material and the characteristics of high strength and corrosion resistance of the stainless steel. Compared with a pure copper vapor chamber, the overall strength of the copper/stainless steel composite vapor chamber is improved by about 30%, and the salt spray resistance experiment is improved by about 50% compared with a copper product. It should be noted that, in practical application, the kind of the material (metal or alloy) to be compounded may be selected according to the requirement of the soaking plate performance, and is not limited to the above-mentioned examples, and may be compounded by three or more.
In addition, the proportion of various materials to be compounded is not limited, and can be freely adjusted according to the required performance.
In the invention, the upper vapor chamber cover 1 and the lower vapor chamber cover 2 can be formed by means of stamping, extruding and etching, and the shapes and the thicknesses of the upper vapor chamber cover 1 and the lower vapor chamber cover 2 are not limited.
In the invention, the supporting column structure 4 can be obtained by sintering point-coated copper powder, and can also be obtained by integrally molding the same material as the lower cover 2 of the soaking plate.
In the invention, the soaking plate upper cover 1 and the soaking plate lower cover 2 can be assembled together by welding through a welding material 5, wherein the welding comprises brazing, diffusion welding and resistance welding.
The soaking plate made of the composite metal material can improve the overall strength of a soaking plate product by about 30% on the premise of ensuring the rest performances and reliability of the soaking plate, and the salt spray resistance experiment is improved by about 50% compared with a copper product. And because it has high strength, can use as the structure according to the application environment, save product space, promote product strength, optimize the assembly process, cost reduction.
