Problems solved by technology

[0004] However, the thickness of the tongue in the above-mentioned centrifugal fan is relatively large, and more materials are used, and the tongue is easy to shrink and deform during molding, resulting in defective products, resulting in higher production costs.

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the embodiments with reference to the accompanying drawings.

[0016] Please refer to figure 1 and figure 2 , the centrifugal fan includes a base 10 , a stator (not shown) and a rotor 20 accommodated in the base 10 , and a cover plate 30 covering the base 10 .

[0017] Please refer to image 3 , the base 10 includes a bottom plate 11 and a side wall 12 extending upward from the periphery of the bottom plate 11 . An air inlet 111 is defined in the middle of the bottom plate 11 corresponding to the position of the rotor 20 . The side wall 12 has a spiral shape, and an air outlet 121 perpendicular to the air inlet 111 is formed on one side thereof. In this embodiment, the rotor 20 rotates counterclockwise, and the air outlet 121 has a near-wind end 1211 on one side and a far-wind end 1212 opposite to the near-wind end 1211 and on the other side. When the centrifugal fan is working, the rotor 20...

Abstract

The invention relates to an eccentric fan comprising a base, a rotor contained in the base and a cover plate covered on the base. The base comprises a soleplate and a side wall extending upwards fromthe soleplate; the side wall is provided with an air outlet with a near air end and a far air end opposite to the near air end; a flow passage is formed between the side wall and the rotor; an air flow generated when the rotor rotates flows along the flow passage from the far air end to the near air end; and the cover plate extends downwards in a position close to the far air end to form a flaky tongue mouth which is arranged in the flow passage and protrudes towards the rotor. The eccentric fan saves more raw materials, is hardly shrunk and deformed in molding and has relatively low production cost.

Description

technical field [0001] The invention relates to a fan, in particular to a centrifugal fan for cooling electronic components. Background technique [0002] With the rapid development of the computer industry, the heat dissipation problem derived from the pursuit of high speed, high function and miniaturization of CPU is becoming more and more serious, which is more prominent in electronic devices with small internal space such as notebook computers. If the heat generated by electronic components such as the CPU cannot be dissipated in a timely and effective manner, the performance of the electronic components will be greatly affected, and the service life of the electronic components will also be shortened. Therefore, it is necessary to dissipate heat from the electronic components. [0003] At present, heat dissipation modules are often used in the industry to dissipate heat from electronic components. The heat dissipation module includes a heat conductor, a radiator, a hea...
