How is the radiator water cooling plate made?

This water-cooling board is made by Wenxuan Thermal, right? Wenxuan this cooling plate is made of aluminum and copper tubes, is made this way: first do a good model of the aluminum plate, and then according to the specific design of the slot in the aluminum plate, at the same time with the bending machine to fold the copper tube into the slot curvature of the same shape, and then press the tube process to do the copper tube pressed into the groove to the side of the tube, the copper tube becomes a D-shaped tube, and then fill the gap with epoxy resin, and then fly the surface of the process to fly a fly, the entire plane will be smooth and flat, and then the surface will be smooth and smooth, and then the surface is smooth and smooth. I used to do this a lot in Wenxuan.
