Abstract

The invention discloses a CPU cooling fan. The CPU cooling fan comprises a fan mounting shell, a motor and fan blades; the fan blades are mounted on the motor; and the motor is fixedly mounted on the fan mounting shell. The CPU cooling fan further comprises a cooling fin accommodating cavity; multiple limiting grooves are formed in the inner surface of the cooling fin accommodating cavity; limiting convex parts matched with the limiting grooves are arranged on the outer surface of the fan mounting shell; and the cooling fin accommodating cavity is mounted on the fan mounting shell through the limiting grooves and the limiting convex parts. The CPU cooling fan is provided with the cooling fin accommodating cavity, so that a cooling metal aluminum fin is positioned in the cooling fin accommodating cavity to preferably take away the heat at the bottoms of the cooling metal aluminum fin to realize a better cooling effect in use.

Description

technical field [0001] The invention relates to a CPU cooling fan, which belongs to the field of CPU fans. Background technique [0002] The existing CPU is generally heated by a fan. Usually, a cooling metal aluminum sheet is installed on the CPU, and a cooling fan is installed on the metal aluminum sheet. The fan generates negative wind pressure to draw away the heat on the aluminum sheet, thereby achieving the purpose of heat dissipation. . Since the fan is generally installed on the top of the metal aluminum sheet, when the height of the metal aluminum sheet is high, the wind pressure at the bottom of the metal aluminum sheet is small, resulting in better fan heat near the fan, while the heat at the bottom is easy to accumulate and the heat dissipation is uneven , affecting the stable operation of the CPU. Contents of the invention [0003] In order to solve the problem of uneven heat dissipation of the existing CPU, the invention provides a CPU cooling fan. [0004...
