How to distinguish the advantages and disadvantages of water-cooled plates in water-cooled radiators

1. Look at the material. Most of the water-cooled heat sinks on the market are designed with aluminum plates and copper pipes buried in them. This type of water-cooled plate is made of aluminum and copper alloy, which has a higher cost-effectiveness and relatively lower cost. It is not difficult for everyone to judge the quality of aluminum and copper, whether there are impurities, or the quality of raw materials.

2. Look at the craftsmanship. The material can be the same but the process is different, but the effect of the radiator is completely different. To see the process, we need to start from two aspects. On the one hand, whether the production is carried out according to the design drawings. Check the parameters indicated in the drawings with a vernier caliper. If the error is within 0.05 millimeters, it can be considered qualified. If the requirement is high, the accuracy can reach 0.02 millimeters.

On the other hand, from the perspective of the workmanship of the water-cooled plate, because the process of burying aluminum plates in copper pipes will cause a problem of adhesion. If there is a gap between the two, it will affect the heat dissipation effect and even lead to water leakage. Another way is to combine copper pipes and aluminum plates through the process of burying pipes, and then treat them with grinding or flying surface technology to form a flat surface for the entire water-cooled heat dissipation plate. The quality can also be judged by observing whether the surface is flat and whether the copper pipes and aluminum plates have merged into a flat surface. Any gaps or unevenness can affect the heat dissipation effect.
