Vansim (Dongguan)Hardware Products Co., Ltd.
What is Vansim's manufacturing process of embedded copper tube liquid cooling plate ?
Design and material selection
- Design: According to the use requirements, use professional software to design the structure of the water cooling plate, determine the size, shape, copper tube layout and other parameters.
- Material selection: Select suitable metal materials, such as aluminum alloy (if the cost is not considered, copper can also be selected as the substrate), because it has good thermal conductivity and corrosion resistance. At the same time, select copper tubes that meet the specifications to ensure its thermal conductivity and strength.
Copper tube processing
- Cutting: According to the design size, use cutting equipment to cut the copper tube into the required length.
- Bending: The copper tube is bent into a predetermined shape by a tube bending machine to adapt to the internal structure of the water cooling plate and ensure a good fit with the components to be cooled.
Substrate processing
- Slotting: According to the size and layout of the copper tube, the corresponding groove is processed on the substrate for placing the copper tube. Usually, a CNC machining center is used for precise slotting.
- Cleaning: Clean the aluminum alloy substrate to remove oil, impurities, etc. on the surface. Chemical cleaning agents or ultrasonic cleaning equipment can be used.

Buried pipe and epoxy filling
-Buried pipe: Put the processed copper tube into the groove of the substrate to ensure that the copper tube fits tightly with the groove wall.
- Glue filling: Use epoxy resin to fill the gap between the copper tube and the substrate. Special attention should be paid to fully stir the epoxy resin to avoid bubbles after drying.
Surface treatment
- Passivation: Passivate the surface of the water-cooled plate to improve its corrosion resistance and wear resistance, and at the same time improve the appearance quality of the surface.
Performance test
- Sealing test: Use water pressure or leakage testing
