How to install the cooling fan？

The composition of the cooling fan mainly includes a group of rings fixed at the end of the motor shaft, and the blades are evenly distributed on the outer circumference of the rings. How is the cooling fan installed? Let's follow Xiao Bian to understand today!
The heat sink is connected with the inner cavity of the ring through the air vent, and the other heat sink is connected with the inner cavity of the ring through two air vents. The column is in the shape of a straight rod. One end of the heat conduction column is close to the side wall of the motor shaft, and the other end of the heat conduction column is located in the heat sink.
However, in the above devices, the blades and rings are generally connected by a fixed structure. When the blade is damaged, it is not convenient to disassemble and replace the blade. The entire cooling fan blade can only be used for maintenance and needs improvement.

The utility model relates to a structure for blade installation, which comprises a ring block connected with a rotating shaft. An installation slot is arranged on the side of the ring block away from the rotating shaft, and a fan blade assembly is arranged in the installation slot. The fan blade assembly consists of one connecting rod, two connecting rods and blades.
One side of the installation groove is equipped with a limit groove, a connecting rod is equipped with a limit block matching with the limit groove, a connecting rod passes through the installation groove, the limit block is set in the limit groove, a sliding groove is opened on the side of the installation groove away from the limit groove, two connecting rods are placed in the limit groove in the sliding groove, and the sliding groove is connected with the limit groove.
By setting the installation slot, the cooling fan assembly can be detachably installed in the installation slot to facilitate maintenance and replacement of the cooling fan assembly. First, install the connecting rod into the limit slot from the installation slot, place the limit block in the limit slot, and align the connection slot with the position of the block to be installed.
