Grooved base With Fins For Soldering Heat Sinks Thermal Solution
Because the size heat sinks is very large normally in high power charging pile cooling solutions. It is a very important problem that
how to improve the heat dissipation performance more effectively.
It has the biggest drawback of this process for solder paste welding process in heat sinks processing field so far. The larger the welding contact area is, the more unstable
welding is. For example, the performance of sealing-off and solder skips affects the effect of cooling. Walmate uses a solution of groove weld fins to solve the problem
that the connection of welding fins and base is not light.
As shown below, each fin is fixed in a groove. It makes fins and a base contact fully to reach heat transfer effect.
