High-radiation film type metal compound material and manufacturing method thereof

Abstract

The invention provides a high-radiation film type metal compound material and a manufacturing method thereof and belongs to the technical field of a high-radiation material. The compound material comprises three parts, namely metal layers, high-radiation film layers and a metal frame, wherein the high-radiation film layers are overlapped with the metal layers and the metal frame is used for cladding the edges of the metal layers and the edges of the high-radiation film layers. The manufacturing method comprises the following steps: firstly, respectively preparing the metal layers and the high-radiation film layers; interactively overlapping the metal layers and the high-radiation film layers till forming overlapping structures with required layer number; utilizing the metal frame to fix the overlapping structures of the metal layers and the high-radiation film layers; heating, thereby melting the contacting metal between the overlapping structures of the metal layers and the high-radiation film layers and between the metal frame and the overlapping structures; and reducing temperature, cooling and solidifying, thereby realizing the integral adhering forming. The structure of overlapped metal layers is adopted and the metal frame is used for cladding and fixing, so that the hardness of a high-radiation film is increased.

Description

technical field [0001] Technical field of high heat dissipation materials. Background technique [0002] Electronic products, machinery, electric power, communications, chemical industry and many other fields will generate different amounts of heat in the process of product processing, production and use. Moreover, if the generated heat cannot be effectively dissipated, it may affect the processing and use of the product. [0003] Various heat dissipation materials are widely used at present. Different types of heat dissipation materials have different properties. For example, metal materials have good thermal conductivity, especially some metal materials, such as copper, aluminum, silver, etc., have particularly good thermal conductivity. For example, copper radiators and aluminum radiators are widely used. [0004] The thermal conductivity properties of some commonly used heat dissipation materials are listed below: [0005] Aluminum: 237W / m K; Copper: 401W / m K; [0...
