Manufacturing technology of foam metal plate for radiator fin

Abstract

The invention discloses a manufacturing technology of a foam metal plate for a radiator fin. The manufacturing technology includes the steps that thermoplastic conducting plastics are made into the foam plate, and the foam plate is bent into the fin; the foam plate serves as a cathode, metal forming the foam metal plate serves as an anode, and the cathode and the anode are soaked into a solution containing metal positive ions of the foam metal plate; the cathode and the anode are connected with a power source, and the power source is connected with a voltage regulation circuit; the voltage size is changed in real time according to the required foam metal deposition speed, and the metal can be deposited; and the thermoplastic conducting plastics in the foam plate are removed through sintering. The manufacturing technology is flexible and ingenious, and the deposition technology and a conducting plastic skeleton are combined; and moreover, the voltage regulating circuit is used for leading the deposition speed, the obtained foam metal plate is in a fin form, and using is made convenient.

Description

technical field [0001] The invention relates to the field of radiators, in particular to a manufacturing process of foamed metal plates for radiator fins. Background technique [0002] Radiators, especially finned radiators, are widely used in electronics, computers, heaters, and auto parts. There are many types of fin designs, but they are not fine enough. After a long time of use, the overall thermal resistance will increase and affect the transmission. Thermal efficiency: The mating surface between the heating element and the radiator is not tight enough, which will also hinder the heat conduction, causing the heating element to accumulate heat and cause local high temperature, which not only affects the service life, but also poses a safety hazard. [0003] The porous structure of the metal foam provides new vitality for the radiator, and its microporous structure greatly increases the specific surface area for heat dissipation. Therefore, it is very wise to use metal f...
