Embodiment Construction

[0050] In order to make the above-mentioned and other objects, features and advantages of the present invention more comprehensible, the preferred embodiments of the present invention are specifically cited below, together with the accompanying drawings, as follows:

[0051] Please refer to Figure 5 and 6 Shown is the cooling fan 1 according to the first embodiment of the present invention. The cooling fan 1 at least includes a fan frame 10 , a base plate 20 , a power connection 30 and a fan wheel 40 . The fan frame 10 can be an axial flow fan frame or a blower fan frame, and the embodiment shown in the figure discloses that the fan frame 10 is a blower fan frame; the base plate 20 is combined inside the fan frame 10 for The fan wheel 40 is driven to rotate; the power connection 30 is electrically connected to the substrate 20 for external power supply; the fan wheel 40 is rotatably combined with the inside of the fan frame 10 to provide a wind-dispelling and heat-dissipatin...

Abstract

A cooling fan comprises a fan frame, a substrate, power supply wiring and a fan wheel, wherein the fan frame is provided with a side wall portion and an axle base; a conductor hole is formed on the side wall portion; the substrate is combined with the fan frame and is provided with an electric port; the electric port faces the conductor hole; one end of the power supply wiring is connected with the electric port and the other end penetrates through the conductor hole; and the fan wheel is combined with the axle base in a rotatable manner. The electric port is positioned on a datum line passing through the axle base and the conductor hole, thus effectively shortening the distance between the electric port and the conductor hole to facilitate assembly operation of the power supply wiring. The power supply wiring can directly penetrate through the conductor hole more uprightly to promote the assembly convenience of the power supply wiring.

Description

technical field [0001] The invention relates to a cooling fan, in particular to a cooling fan which is easy to install for power supply wiring. Background technique [0002] Existing cooling fans usually have a power connection so that an external power supply can be used for the cooling fan to work. Generally speaking, the fixed position of the power wiring must be properly arranged to ensure that the cooling fan can effectively prevent the power wiring from loosening or being involved in the cooling fan during the actual work process, so that the cooling fan can work normally ; and in terms of various cooling fans that are common in the market at present, most of the power wiring must be fixed through a rather complicated way of winding, causing a lot of inconvenience in assembly. [0003] For example, please refer to figure 1 As shown, as China Taiwan Announcement No. 502821 "Fan Wire Management Structure" new patent discloses the first existing cooling fan 70, the cool...
