Description
Technical Field
The invention relates to the technical field of cooling fans, in particular to a thin type side-in and side-out cooling fan.
Background
The existing heat radiation fan is divided into an axial flow type and a centrifugal type, an axial flow type air inlet mode axially enters and axially exits, and the axial flow heat radiation fan is required to be assembled above a heat source when being applied to various products, has larger axial size and is limited by the thickness of a heat radiation system, so the fan cannot be used; the upper air inlet and the lower air inlet are in a centrifugal air inlet mode and are laterally exhausted, the thickness of a heat dissipation system is limited, a fan can be only transversely arranged, and an air inlet is formed in the surface of a base of the heat dissipation system due to the fact that the upper air inlet and the lower air inlet are needed; in view of these drawbacks, it is necessary to design a thin side-in and side-out heat dissipation fan.
Disclosure of Invention
The invention aims to provide a thin side-in and straight-out cooling fan, which is light and thin, improves air inlet conditions, develops a novel air inlet mode and improves the cooling efficiency of the fan.
The purpose of the invention can be realized by the following technical scheme:
the thin type side-in and side-out radiating fan comprises a frame body, an air inlet, a rotating shaft, blades, a rotating groove and a flow guide groove, wherein the frame body is of a hollow structure, the rotating groove is formed in the center of the top of the frame body, the flow guide groove is formed in the edge of the top of the rotating groove, the air inlet is formed in each of four side faces of the frame body, the air inlet and the rotating groove are communicated with an inner cavity of the frame body, a plurality of blades are uniformly arranged on the outer side of the rotating shaft, the bottom end of the rotating shaft is rotatably connected with the center of the inner wall of the bottom;
wherein, the diversion trench is in an open shape from bottom to top.
The invention has the beneficial effects that: the air inlet is arranged on the side face of the frame body, the air is vertically upwards exhausted, the air inlet groove can be conveniently formed in the periphery of the side face of the equipment, the side face of the equipment is free of shielding in the using process, a better air inlet condition can be obtained, the vertical direction is not limited by the thickness of a heat dissipation system, the height of the fan can be designed to be 2.5 mm-20 mm, the air inlet groove can be widely used, the structure 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.
