Description

Technical field

[0002] The utility model relates to the technical field of heat dissipation of electronic components, and in particular to a high-efficiency radiator made of polymer graphene. [Background Technology]

[0004] In electronic devices such as computers, laptops, LED lighting, communication transmitters, and high-power amplifiers, the high heat generated and the high temperature caused by heat accumulation will seriously affect the life and performance of electronic components. Based on the above situation, heat sinks are configured in computers, servers, lighting, communications, energy storage, rectifiers and other equipment to dissipate heat and cool down the heat-generating components.

[0005] Traditional radiators are usually made of metal aluminum, aluminum alloy, metal copper, ceramics and other materials. However, with the expansion and popularization of the application scope of electronic and electrical equipment, the performance and structural requirements of electronic and electrical equipment are becoming more and more stringent and complex. The radiators made of materials such as copper, aluminum, and ceramics in the existing technology are based on the principle that copper, aluminum, and aluminum alloy absorb heat and then dissipate it into the surrounding environment. Such radiators are generally equipped with cooling blades and fans. The fan relies on forced convection of air between the cooling blades to remove heat, and the convection method is used to achieve the heat dissipation effect.

[0006] Aluminum alloy materials have good heat dissipation effects, but the material itself has a high density and large mass, and requires multiple machining processes to obtain a better radiator product. It can only be processed in the vertical and horizontal directions and cannot be processed into curved shapes such as circular arcs. If curved shapes need to be processed, the forging cost investment needs to be increased.

[0007] Existing metal copper and metal aluminum heat dissipation materials generally use forced convection, which will produce serious heat imbalance in dead corners where forced convection does not pass, resulting in low heat exchange or local excessive temperature problems. [Summary of the invention]

[0009] Based on the above technical background, the utility model uses polymer graphene material to make a graphene radiator with good heat dissipation effect, light weight and low processing difficulty, and changes the forced convection mechanism to a thermal radiation heat dissipation mechanism, avoiding the problems of low heat exchange in non-convection areas or excessively high local temperatures.

[0010] The graphene radiator involved in the utility model comprises a heat dissipation substrate and fins arranged on the heat dissipation substrate. The heat dissipation substrate and the fins are integrally formed by injection molding of a graphene polymer material, or the heat dissipation substrate is made of an alloy material and the fins are injection molded thereon by using a graphene polymer material.

[0011] The alloy material used to make the heat dissipation substrate includes but is not limited to copper alloy, aluminum alloy, silver alloy or gold alloy.

[0012] The fins are of a single convoluted structure or a multi-fin array structure.

[0013] The fin is a convoluted structure in which the fin is vertically arranged on the heat dissipation substrate, with the outer contour of the heat dissipation substrate as the outermost shape, forming a multi-channel convoluted structure.

[0014] The fins are arranged in a plurality of rows, forming an array structure with equal spacing.

[0015] The fins include several rows, each row has several independent fins, and the fins are tubular or columnar structures.

[0016] The fins comprise a multi-row structure of an array, and the heights of the multiple rows of fins are different, and the heights of the multiple rows of fins present a linear height difference.

[0017] The fins include multiple rows of single fins, each fin occupies one row, and each fin is in a rectangular corrugated shape.

[0018] The graphene radiator involved in the utility model utilizes polymer graphene material to produce a graphene radiator with good heat dissipation effect, light weight and low processing difficulty. The structure of the fins is improved, and the forced convection mechanism is changed to a thermal radiation heat dissipation mechanism by utilizing the properties of graphene, thereby avoiding the problems of low heat exchange in non-convection areas or excessively high local temperatures.
