Abstract

A cooling fan, which may be installed on a corresponding position of the cooling fins of a CPU or a cooling hole-plate of a computer mainframe, includes: a fan body (3), a fan frame (2) and a fan impeller (1). The fan frame (2) is circular in shape. The fan body (3) is arranged along the outer circumference of the fan frame (2). The fan impeller (1) is installed in the fan frame (2). A rubber layer (4), which is formed by secondary injection molding, is arranged at the outer surface of the fan body (3) and the contact parts between the cooling fins and the upper and lower edges of the fan frame (2), respectively. Through holes (31) are provided at the upper and lower parts of four end corners of the fan body (3), respectively, and rubber layers are also provided at the inner walls of the through holes, so that after secondary injection molding, the upper edges of the through holes are made level with the corresponding upper and lower edges of the fan frame (2). The present invention can achieve flexible touch between the cooling fan and the cooling fins or the cooling hole-plate of a computer mainframe, thereby effectively offsetting longitudinal and transverse impact and vibration and reducing noise.

Description

technical field [0001] The invention relates to a cooling device, in particular to a CPU cooling fan. Background technique [0002] With the rapid development of the information industry and the continuous improvement of the operating speed of electronic components, the waste heat generated by the operation of computer systems has also increased significantly. If the waste heat generated during the operation of the computer system is not dissipated, the performance of the computer system will be reduced, and even the computer system will be damaged. Therefore, a cooling device is needed to dissipate the waste heat generated during the operation of the computer system. The heat dissipation device commonly used in computer systems is a fan. In order to pursue better heat dissipation efficiency, the speed of the heat dissipation fan used is getting faster and faster. However, the vibration frequency caused by the high-speed running fan is also increased. The cooling fan instal...
