The cooling grooves are distributed in petals, and multiple heat dissipation grooves work at the same time, which effectively improves the cooling efficiency.

The front end of the heat sink is designed with an air trap groove, which can effectively increase the air flow and at the same time facilitate the disassembly of the wheel spacers.

The aerodynamic arc-shaped design of the heat sink is conducive to the rapid flow of air and further improves the cooling efficiency.

The cooling groove uses a symmetrical design, whether it is on the left wheel or the right wheel, forward or reverse, the purpose of heat dissipation can be achieved normally and effectively.
