Embodiment Construction

[0014] Please refer to FIG. 2 , which is an exploded view of a preferred embodiment of the blower fan of the present invention.

[0015] Please also refer to FIG. 3 , which is a perspective view of a preferred embodiment of the blower fan of the present invention. A blower fan includes a blade set 100 , a rotor 200 , a stator 300 and a casing 400 .

[0016] The casing 400 includes an air box 410 and an air outlet 420 , and a constricted portion is formed between the air box 410 and the air outlet. The bellows 410 includes a bottom 411 , and the stator 300 is integrally formed with the bottom 411 . The rotor 200 is pivotally sleeved on the stator 300 .

[0017] The blade set 100 is sheathed on the rotor 200 . The rotor 200 can drive the blade set 100 to rotate synchronously. Since the rotor 200 rotates at a high speed, the vibration is transmitted to the housing 400 through the rotor 200 through the stator 300 . A sheet-shaped reinforcing rib 500 is provided at the constric...

Abstract

The invention relates to blast fan. It includes one shell formed by one air box and one air outlet between which there is one necking part set one reinforcing rib to increase shell structure strength. While the blast fan is rotating at high speed, the reinforcing rib can reduce shell vibration, thereby reduce noise.

Description

【Technical field】 [0001] The invention relates to a blower fan. 【technical background】 [0002] General electronic equipment such as computers will generate heat during operation. If the heat is not discharged in time, the heat will accumulate and eventually cause the equipment to fail to operate or even be damaged. The main heat source in the computer is the central processing unit and the power supply in the computer case. In the prior art, the heat generated by the central processing unit is usually discharged by installing a radiator on the central processing unit and a fan on the radiator. , In addition, a fan is also installed in the power supply to discharge the heat generated by it. [0003] With the continuous development of the computer industry, the high frequency and high power of computers have brought new problems to heat dissipation. In order to achieve better heat dissipation effects, the industry uses blower fans to replace ordinary fans. Blower fans are u...
