Problems solved by technology
[0005] First, after the centrifugal cooling fan is installed, if the distance between the axial air inlet of the centrifugal cooling fan and the inner wall of the electronic product (or related components inside the electronic product) is too small, it will easily lead to the The axial air inlet cannot effectively introduce enough airflow and generate noise, which will affect the overall cooling effect and service life of the centrifugal cooling fan
[0006] Second, after the centrifugal cooling fan is installed, if the distance between the axial air inlet of the centrifugal cooling fan and the inner wall of the electronic product (or related components inside the electronic product) is too large, although it can ensure The axial air inlet has enough space to introduce airflow, however, it is relatively easy to occupy too much space inside the electronic product, making it difficult to develop and design the electronic product in the direction of miniaturization

The invention discloses a centrifugal radiating fan which comprises a frame, a motor, a wheel and at least one height positioning part. The frame comprises a base plate and a cover plate, a side wall is arranged between the base plate and the cover plate, an air inlet is formed in the cover plate, and an air outlet is formed in the side wall; the motor is arranged inside the frame; the wheel is rotatably combined with the motor; the height positioning parts are arranged at the peripheral edge of the air inlet of the frame, each height positioning part comprises a combination end and a butting end, each combination end is combined with the cover plate of the frame, and each butting end is distanced from the cover plate. The centrifugal radiating fan has the advantages that sufficient airflow can be assuredly led in by the aid of the centrifugal radiating fan, and accordingly a good radiating effect can be realized.
Description
technical field [0001] The present invention relates to a heat dissipation fan, in particular to a centrifugal heat dissipation fan capable of introducing airflow from an axial air inlet and laterally exporting airflow through a radial air outlet. Background technique [0002] Existing heat dissipation fans generally include two types: axial flow heat dissipation fans and centrifugal heat dissipation fans. Among them, the axial flow cooling fan has an axial air inlet and an axial air outlet opposite to each other in the axial direction, so that the airflow can be introduced through the axial air inlet, and then the airflow can be exported through the axial air outlet to provide heat dissipation. Also, the centrifugal cooling fan has an axial air inlet in the axial direction, and a radial air outlet in the radial direction, so that the airflow is introduced through the axial air inlet, and then guided laterally through the radial air outlet. Out of the air, but also has the ...
