Embodiment Construction

[0061] In order to achieve the above-mentioned purpose and effect, the technical means and structure adopted by the present invention are hereby illustrated in detail with respect to the preferred embodiments of the present invention. Its features and functions are as follows, so that it can be fully understood.

[0062] However, in the present invention, the aluminum heat dissipation fins in the heat dissipation module are partially plated with nickel by physical vapor deposition. In the present invention, the plasma sputtering method is preferably used for illustration.

[0063]The PVD method uses methods such as vacuum, sputtering, ionization, or ion beams to volatilize pure metals and interact with gases such as hydrocarbons and nitrogen, while plasma sputtering is a partially ionized gas. By applying a voltage on two corresponding metal electrode plates, if the concentration of gas molecules between the electrode plates is in a certain range, the secondary electrons genera...

Abstract

The invention discloses a manufacturing method of a radiating module, which mainly comprises the following steps: partially plating radiating fins and heat conducting tubes, which are made of two different metal materials, by a physical vapor deposition method, painting solder on the part which is partially plated, heating the solder till the solder reaches the melting point, welding the radiating fins and the heat conducting tubes so that the radiating fins and the heat conducting tubes are combined and formed into a radiating module structure. By the method for partially plating the radiating fins, the radiating fins and the heat conducting tubes can be welded even if the radiating fins and the heat conducting tubes are made of different metals so that the radiating fins and the heat conducting tubes can be firmly combined and has a superexcellent heat conducting effect.

Description

technical field [0001] The present invention relates to a method for manufacturing a heat dissipation module, in particular to a method for manufacturing a heat dissipation module that increases the bonding between heat dissipation components and is environmentally friendly during manufacture. Background technique [0002] In the conventional heat dissipation module, when the heat pipe and the heat dissipation fin need to be combined, it is usually necessary to combine the two first and then weld and fix the contact parts of the two to make the two firmly combined, but often if the two are different Properties of different metals (such as heat pipes made of copper, cooling fins made of aluminum) because the aluminum itself cannot be combined with other materials using general welding methods, so special welding methods (such as argon welding) are required for welding. The welding method is only suitable for welding between aluminum and aluminum materials; however, this weldi...
