New technology cold plate. You can learn about it, new process of cold plate–dry pressing, without epoxy resin. We rivet the copper tube into the slot of the aluminum plate, without epoxy resin, but use the mold to flatten the copper tube, stuck in the aluminum plate will not fall off.

You may think you don’t have to go through all this trouble and just use the lowest cost epoxy process, but due to the environmental requirements of some products, epoxy is not allowed. In this case, you can use the new process of dry pressing, and you may also say that you can weld the copper tube to the aluminum plate, yes, the copper tube welding aluminum plate this solution is possible, but first need to be nickel-plated aluminum plate, and then welding, the cost is very high. This new process of dry pressing will solve the two requirements of not using epoxy resin and ensuring low cost, which is your choice.
