Heat dissipation structure and method for manufacturing same

Abstract

The present application provides a heat dissipation structure and a method for manufacturing the same. The heat dissipation structure comprises a magnetic conductive member and a bottom plate. The bottom plate is provided with a shaft tube thereon, and is provided with a through-hole arranged around the shaft tube. The through-hole accommodates the magnetic conductive member. A sticker is attachedto a surface of the bottom plate facing away from the shaft tube. The sticker covers the through-hole, and the magnetic conductive member is attached and fixed to the sticker. In contrast to the prior art, when the bottom plate of the present application is manufactured, it is not required to integrate the magnetic conductive member into the bottom plate, thereby simplifying processes and improving efficiency. Moreover, a use of the sticker to fix the magnetic conductive member enables multiple functions of the sticker and reduces costs.

Description

technical field

[0001] The present application relates to the technical field of heat dissipation, in particular to a heat dissipation structure and a method for manufacturing the heat dissipation structure. Background technique

[0002] In the existing heat dissipation structure, a magnetic conductive member is often provided to limit the position of the rotor of the heat dissipation structure when it stops, so as to activate the rotor when starting. In the existing heat dissipation structure, the magnetic conductive part is usually made as a whole with the bottom plate of the heat dissipation structure. The process is usually to use a mold for one-time molding, that is, first set a groove for the magnetic conductive part on the mold, and put the magnetic conductive part into the In the groove, make the bottom plate again. This process has the following problems: due to the small size of the magnetic parts, it is inconvenient to manually place them into the groove of the m...
