Cylindrical pin fin heat sink comprises a base and a plurality of needle cylindrical columns. One side of the base is a heat source contact surface, and the other side is a heat dissipation surface.
A plurality of needle cylindrical columns are vertically arranged on the heat dissipation surface of the base. The base and the needle columns are integrally formed, and the needle columns are in the shape of cylinder.
Since the base is integrally formed with a plurality of needle columns, the stability of the connection between the needle column and the contact surface of the base can be guaranteed.
At the same time, because the needle column of the heatsink is a cylinder shape, it is easy to demould the needle radiator when preparing it, which is simple and convenient.
Moreover, the cylindrical shaped needle column has small resistance to the heat exchange medium, and the heat exchange speed is fast, so the heat dissipation is good.
When customize a cylindrical pin heat sink, we need consider about the pin fin array design , it has a huge impact on the overall performance of the heat sinks, and need optimize the pin fin gap distance, make the air flow have an ideal flow direction.
