Problems solved by technology

At present, high performance and small size are the development trend of cooling fans. Most of the existing cooling fans achieve the effect of increasing the air volume by replacing more advanced components or increasing the size of the motor; this leads to a sharp increase in cost and limits the further improvement of fan performance.

Embodiment 1

[0021] Such as Figure 1-3 As shown, a cooling fan with a large air volume includes a fan frame 1, a motor mounting base 2, a motor and a fan body 3, and the motor mounting base 2 is fixed to the rear air inlet of the fan frame 1 through a deflector 4, The motor is installed in the motor mounting seat 2, the fan body 3 is mounted on the output shaft of the motor, and there are at least three guide vanes 4, which are uniformly distributed around the motor mounting seat 2, so The guide vane 4 is arc-shaped, and the rear side surface of the guide vane 4 is a forward concave arc surface, and the front side surface is a forward convex arc surface.

[0022] Any one of the deflectors 4 is provided with an outer wire inlet 5 at the outer end connected to the fan frame 1, and an inner wire inlet 6 is opened at the inner end connected with the motor mounting base 2. The rear side of the deflector 4 is The curved surface concave forward is the wire inlet groove 7.

Abstract

The invention discloses a large-air-volume cooling fan which comprises a fan frame, a motor installation seat, a motor and a fan body. The motor installation seat is fixed to a rear air inlet of the fan frame through flow deflectors, the motor is installed in the motor installation seat, the fan body is installed on an output shaft of the motor, the number of the flow deflectors is at least three,the flow deflectors are circumferentially and uniformly distributed by taking the motor installation seat as the center, the flow deflectors are arc-shaped, the rear side surfaces of the flow deflectors are arc-shaped surfaces which are concave forwards, and the front side surfaces of the flow deflectors are arc-shaped surfaces which are convex forwards. Due to the adoption of the arc-shaped flowdeflectors, the production cost is not increased, the pressurizing effect is achieved, the air volume can be greatly increased, the backward arc surfaces of the flow deflectors can be directly used as wire inlet grooves of wires, and the structure is more reasonable.

Description

technical field [0001] The invention relates to a cooling fan with a large air volume. Background technique [0002] Cooling fans generally refer to fans used for cooling CPU, graphics cards and other motherboards. Some cooling fans are also equipped with heat sinks. In fact, the main purpose is to conduct heat and blow it into the nearby air to achieve the effect of cooling. The above-mentioned type of heat dissipation fans are also widely used in metal cabinet doors such as cabinets and electric control cabinets, and generally do not need a heat sink structure. At present, high performance and small size are the development trend of cooling fans. Most of the existing cooling fans achieve the effect of increasing the air volume by replacing more advanced components or increasing the size of the motor; this leads to a sharp increase in cost and limits the further improvement of fan performance. Contents of the invention [0003] In view of the above problems, the present ...
