Damping and cooling structure of case fan

Abstract

The invention discloses a damping and cooling structure of a case fan. The damping and cooling structure comprises a mounting plate; a filtering plate is arranged above the mounting plate; a pluralityof vent holes for mounting fans are formed in the mounting plate; a plurality of damping grooves are formed around the vent holes in the mounting plate; cooling silica gel is arranged on the bottom surfaces of the damping grooves; buffer rings are arranged on the side surfaces of the damping grooves; damping screws are arranged in the damping grooves in a penetrating mode; the damping screws sequentially penetrate through the cooling silica gel, the fans and the filtering plate; a rotating arm is arranged at one end of the filtering plate; the rotating arm is rotationally connected with the mounting plate; fixed pieces connected with the damping screws are arranged on the front side and the rear side of the filtering plate respectively; sliding rods arranged in the length direction of thefiltering plate are arranged above the fixed pieces; a cleaning brush strip arranged in the width direction of the filtering plate is arranged on the sliding rods; and the two ends of the cleaning brush strip are in sliding connection with the sliding rods. The damping and cooling structure has the characteristics of good cooling performance, high stability and difficulty in generating vibrationand noises.

Description

technical field [0001] The invention relates to a fan structure, in particular to a shock-absorbing and heat-dissipating structure of a chassis fan. Background technique [0002] In the prior art, the chassis contains a large number of electronic components, which generate a large amount of heat during operation, and the accumulation of heat will damage the electronic components and circuits. Therefore, the chassis requires relatively high heat dissipation performance. Existing chassis generally use fans to dissipate heat. However, the fan itself generates heat when it is working, and the heat is not easy to dissipate, resulting in increased heat in the chassis. Moreover, the installation structure of many fans is not stable. When the fan is running at a high , the faster the rotation speed, the greater the vibration, and air and mechanical noise will be generated. Therefore, the fan structure in the existing frequency conversion chassis has the problems of unsatisfactory he...

Problems solved by technology

Existing chassis generally use fans to dissipate heat. However, the fan itself generates heat when it is working, and the heat is not easy to dissipate, resulting in increased heat in the chassis. Moreover, the installation structure of many fans is not stable. When the fan is running at a high , the faster the rotation speed, the greater the vibration, and air and mechanical noise will be generated. Therefore, the fan structure in the existing frequency conversion chassis has the problems of unsatisfactory heat dissipation performance, stable performance to be improved, and easy vibration and noise.
