Thin-type side-in and straight-out heat dissipation fan

Abstract

The invention discloses a thin-type side-in and straight-out heat dissipation fan. The heat dissipation fan comprises a frame body, air inlets, a rotating shaft, blades, a rotating groove and a flow guiding groove; the frame body is of a hollow structure, the rotating groove is formed in the center position of the top of the frame body, the flow guiding groove is formed in the edge of the top of the rotating groove, the air inlets are formed in the four side faces of the frame body, each air inlet and the rotating groove communicate with the inner cavity of the frame body, the plurality of blades are uniformly arranged on the outer side of the rotating shaft, the bottom end of the rotating shaft is rotationally connected with the center of the inner wall of the bottom of the frame body, and the rotating shaft and the blades are located in the rotating groove; and the flow guiding groove is in an open shape from bottom to top. According to the heat dissipation fan, the heat dissipationfan is light and thin, the air inlet condition is improved, a novel air inlet mode is developed, and the heat dissipation efficiency of the fan is improved.

Description

technical field [0001] The invention relates to the technical field of cooling fans, in particular to a thin side-entry and straight-out cooling fan. Background technique [0002] At present, cooling fans are divided into axial flow type and centrifugal type. The axial flow air inlet mode is axially in and axially out. When the axial flow cooling fan is applied to various products, it must be assembled above the heat source. The axial size is relatively large, which is limited by the thickness of the cooling system. , this kind of fan cannot be used; the centrifugal air intake method is up and down, and the air is blown out sideways. Due to the thickness limit of the cooling system, the fan can only be placed horizontally. Because the upper and lower sides need to enter the air, the air inlet is opened on the base of the cooling system, and the equipment is in use. During the process of placing objects on the surface, the air inlet will be largely covered, and the air inlet ...

[0002] At present, cooling fans are divided into axial flow type and centrifugal type. The axial flow air inlet mode is axially in and axially out. When the axial flow cooling fan is applied to various products, it must be assembled above the heat source. The axial size is relatively large, which is limited by the thickness of the cooling system. , this kind of fan cannot be used; the centrifugal air intake method is up and down, and the air is blown out sideways. Due to the thickness limit of the cooling system, the fan can only be placed horizontally. Because the upper and lower sides need to enter the air, the air inlet is opened on the base of the cooling system, and the equipment is in use. During the process of placing objects on the surface, the air inlet will be largely covered, and the air inlet conditions are unfavorable, which cannot achieve a good heat dissipation effect; in view of these defects, it is necessary for us to design a thin side-in and straight-out cooling fan
