Problems solved by technology

[0003] The CPU cooling fans widely used in the market are made of pure plastic. Because of the injection molding structure, it is difficult to increase the number of fan blades. The impeller has high strength and light weight and cannot have both. The air outlet direction is parallel to the fan axis, and the cooling effect is not ideal.

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with specific embodiments.

[0024] Such as Figure 1 to Figure 3 As shown, a CPU cooling fan of the present invention includes a fixed disk 1, an inner fixed ring 2 covering the edge 11 of the fixed disk 1, more than 10 fan blades 3 annularly distributed on the outside of the inner fixed ring 2, and a The outer fixing ring 4 fixed on the outer side of the blade 3, the fan blade 3 has a folded structure and is narrow inside and wide outside. There is an air outlet channel between the adjacent fan blades 3. When the cooling fan is rotating, the air is thrown out of the side of the cooling fan in the radial direction by the fan blades 3 of the pleated structure. The air volume is large and the cooling effect is good. The more fan blades 3, the larger the active area, and the greater the wind force, the better the heat dissipation effect.

[0025] Such as image 3 and Figure 4 As shown, a n...

Abstract

The invention belongs to the technical field of computer accessory processing and relates to a CPU (Central Processing Unit) cooling fan. The CPU cooling fan comprises a fixing plate, an inner fixing ring covering the edge of the fixing plate, a plurality of fan blades annularly and evenly distributed on the outer side of the inner fixing ring, and an outer fixing ring fixed to the outer sides of all the fan blades. The fan blades are of a folded structure. The outer fixing ring is provided with an annular base part and upright parts protruding out of the base part, wherein outer clamping seams perpendicular to the base part are formed in the upright parts. The outer sides of the fan blades are provided with clamping claws clamped in the outer clamping seams. According to the CPU cooling fan, air can be thrown out of the side face of the cooling fan in the radial direction through the fan blades of the folded structure, the air volume is large, and the cooling effect is good.

Description

technical field [0001] The invention relates to the technical field of computer accessories processing, in particular to a CPU cooling fan with good heat dissipation. Background technique [0002] The central processing unit (CPU, Central Processing Unit) is a very large-scale integrated circuit, which is the computing core and control core of a computer. During work, the CPU emits a lot of heat. In order to ensure the normal operation of the CPU, a special cooling fan is required to cool down the CPU. The quality of the CPU cooling fan will even restrict the performance of the computer. [0003] The CPU cooling fans widely used in the market are made of pure plastic. Because of the injection molding structure, it is difficult to increase the number of fan blades. The impeller has high strength and light weight. [0004] Therefore, it is necessary to provide a new CPU cooling fan to solve the above problems. Contents of the invention [0005] The main purpose of the pr...
