Description

Fan capable of raising wind pressure

This new model relates to a fan, especially a fan that can increase air pressure.

With the advancement of technology, the functions of computers and other 3C products are becoming more and more diversified, and the operating efficiency is getting higher and higher, so that the internal electronic components generate more heat, so most of the electronic components require heat dissipation devices. To dissipate heat, to prevent the high temperature of electronic components from affecting performance and stability during operation. Among them, a cooling fan is a common heat sink.

However, in general, existing fans often have problems such as inconcentration of air output and insufficient air pressure, which leads to poor heat dissipation efficiency and cannot effectively dissipate the densely arranged electronic component areas or other places with high heat accumulation. Pressure and wind speed can be used to enhance the heat dissipation effect. Only by increasing the speed, it will cause excessive power consumption and excessive noise.

In view of this, the creators of the new type devote themselves to the above-mentioned shortcomings of the existing technology, especially concentrated research and the application of academic theory, try their best to solve the above problems, which becomes the goal of the new type of creators' improvement.

The main purpose of the present invention is to increase the wind pressure of the fan and reduce the noise generated during operation.

In order to achieve the above objective, the present invention provides a fan capable of raising wind pressure, which includes a fan frame, a fan wheel and a plurality of stationary blades. The fan frame includes a frame body, a bearing seat and a connecting frame formed inside the frame body The body and the plurality of arms of the bearing seat are rotatably arranged on the bearing seat, and each stator blade system extends from the frame body toward the bearing seat and is not connected with the bearing seat.

In order to achieve the above objective, the present invention provides a fan capable of raising wind pressure, which includes a fan frame, a fan wheel and a plurality of stationary blades.

The detailed description and technical content of the present invention will be described as follows in conjunction with the drawings. However, the drawings are only for illustrative purposes and are not intended to limit the present invention.

This model provides a fan that can increase the wind pressure. Please refer to Figures 1 to 4, which is the first embodiment of the present model. It includes a fan frame 1, a fan wheel 2 and a plurality of stationary blades 3. The fan frame 1 is formed by plastic injection molding, which includes a frame 11, a bearing seat 12 formed inside the frame 11, and a plurality of arms 13 connecting the frame 11 and the bearing seat 12. The fan wheel 2 is plastic injection It is formed by integral molding, which is rotatably arranged on the bearing base 12. Each stator blade 3 is formed by plastic injection integral molding. Each stator blade 3 extends from the frame 11 toward the bearing seat 12 and is not connected to the bearing seat 12 12Connect.

To further illustrate, the fan wheel 2 has a hub 21 and a plurality of fan blades 22 extending from the hub 21. The surface area of each stator blade 3 is smaller than that of each fan blade 22, and an air inlet is provided on both sides of the fan frame 1. 14 and an air outlet 15, the bearing seat 12, each arm 13 and each static blade 3 are arranged at the air inlet 14, wherein when the fan wheel 2 rotates, wind is drawn in through the air inlet 14 and passes through each static blade 3 After the airflow is compressed and concentrated and the wind pressure is increased, the wind pressure is increased a second time through the blades 22 of the fan wheel 2, and finally blown out from the air outlet 15, thereby increasing the wind pressure of the fan and reducing the noise generated during operation .

Wherein, the frame body 11 is provided with a plurality of through holes 111, and each through hole 111 is respectively used for a screw fixing element to be locked, so that the fan frame 1 can be fixed.

Please refer to FIG. 5, which is the second embodiment of the present invention, which includes a fan frame 1, a fan wheel 2 and a plurality of stator blades 3. The fan frame 1 is formed by plastic injection molding and includes a frame body 11. A bearing seat 12 formed inside the frame body 11 and a plurality of arms 13 connecting the frame body 11 and the bearing seat 12, the fan wheel 2 is formed by integral injection molding of plastic, which is rotatably arranged on the bearing seat 12 Above, each stator blade 3 is formed by plastic injection integral molding, and each stator blade 3 extends from the carrier 12 toward the frame 11 and is not connected to the frame 11.
