Problems solved by technology

Because the upper edge of the support bar or the vane 13 is horizontal, the airflow brought by the rotation of the blade 121 on the windward side will arrive at the support bar or the vane 13 at the same time, and the bottom edge of the blade 121 and the support bar Or the distance h between the upper edges of the vane 13 is relatively short, and when the airflow passes through it, it will stimulate a large noise value and produce poor sound quality in a short period of time

Embodiment Construction

[0053] First, see figure 2 , which shows the first preferred embodiment of the cooling fan of the present invention. The cooling fan includes a frame body 20; a base 21 arranged in the frame body 20; 23 is located at the air outlet side of the cooling fan. Certainly, the air guiding component 23 can also be arranged on the air inlet side of the cooling fan, or be located on the air inlet side and the air outlet side of the cooling fan at the same time. The heat dissipation fan has an impeller 22, which has a hub 221 and a plurality of fan blades 222 arranged around the hub. The top periphery of the hub 221 has a curved structure 221a to guide more air flow to The fan blade 222 . The shape of the frame is in addition to the figure 2 Instead of being shown as a square configuration, it could also be a rectangular or circular configuration. The frame body 20 , the base 21 and the plurality of flow guiding components 23 can be made by integral injection molding, and the mat...

Abstract

A heat emission fan with an up forward flow guider comprises a frame, an impeller formed by a wheel hub and motive blades around the hub, a base fixed in the frame to support the impeller, and a flow guide set fixed in between the base and the frame. One end of the flow guide set which is fixed to the windward side or the lee side is inclination to the horizontal line vertical to the axes.

Description

technical field [0001] The invention relates to a cooling fan and its fan frame structure, in particular to an axial flow cooling fan and its fan frame structure. Background technique [0002] In general electronic products (such as computers), since the electronic components in them generate a lot of heat during operation, if they are kept at high temperature, it will easily lead to wear and tear of the electronic components and shorten their lifespan. Therefore, in order to prevent electronic components from malfunctioning, cooling fans are generally provided therein to dissipate the heat generated inside to the outside. [0003] see figure 1 , which is a traditional commonly used axial flow fan, the axial flow fan has a housing 10, a motor 11 and an impeller 12. The casing 10 has a base 14 for receiving the motor 11 , and a plurality of strip-shaped support rods or vanes 13 are provided at the air outlet end of the casing 10 . When the motor drives the impeller 12 to r...
