Description

In this way, it is equivalent to separately arranging the motor and the fan, resulting in a relatively large and non-compact structure. At the same time, the wind force is small and the heat dissipation performance is poor.

[0004] Therefore, the existing technology still needs to be improved and developed. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a fan with good heat dissipation performance, greater wind force and good heat dissipation performance in view of the above-mentioned defects of the existing technology.

[0006] The technical solution adopted by the utility model to solve the technical problem is as follows:

[0007] A fan with good heat dissipation performance, comprising:

[0008] A cylindrical housing, the top of the cylindrical housing is covered with an upper cover, a partition is arranged in the cylindrical housing, a hollow guide post is arranged on the partition, and the partition divides the cylindrical housing into an upper housing and a lower housing;

[0009] A brushless motor and a control circuit board for controlling the brushless motor are arranged in the lower housing, a guide vane impeller is arranged on the output shaft of the brushless motor, and the guide vane impeller is located in the upper housing;

[0010] An air inlet pipe is arranged in the middle of the upper cover, and an air outlet pipe is arranged on the upper housing:

[0011] The guide vane impeller includes an upper rotating plate, a lower rotating plate, and a plurality of arc-shaped guide vanes arranged between the upper rotating plate and the lower rotating plate.

[0012] Preferably, the brushless motor includes a rotor arranged on the output shaft, a coil stator arranged on the control circuit board, and an outer cover arranged on the output shaft.

[0013] Preferably, a heat dissipation mechanism is arranged on the inner side of the outer cover.

[0014] Preferably, the heat dissipation mechanism includes a support frame, a main heat dissipation plate arranged on the support frame, and a plurality of arc-shaped heat dissipation plates arranged on the main heat dissipation plate.

[0015] Preferably, four arc-shaped heat dissipation plates are provided.

[0016] Compared with the prior art, the fan with good heat dissipation performance provided by the present utility model has the following beneficial effects:

[0017] Due to the provision of the air guiding impeller, the wind force is greater, and at the same time, it directly dissipates heat inside the brushless motor, with good heat dissipation effect, making the overall heat dissipation performance of the fan excellent. Description of the Drawings
