Embodiment Construction

[0028] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0029] Such as figure 1 As shown, a cooling fan metal base includes: an integrally formed upper cover 1, a side wall 2 and a base 3, the metal cooling fan base is a disc-shaped structure with a hollow cavity, and the hollow cavity is used to accommodate For the cooling fan, the upper and lower ends of the side wall 2 are respectively connected to the edges of the upper cover 1 and the base 3, and the upper cover 1, the side wall 2 and the base 3 are all made of metal.

[0030] Further, the outer side of the side wall 2 is evenly provided with at least two fixing pieces 4 for fixing the metal base of the cooling fan in the chassis. The fixing part 4 is used to fix the cooling fan base 3 on the chassis. Specifically, the fixing part 4 is provided with at least one fixing hole 5, and the fixing plane ...

Abstract

The invention relates to the technical field of cooling equipment, in particular to a metal base of a cooling fan. The metal base of the cooling fan comprises an upper cover, a side wall and a base body, wherein the upper cover, the side wall and the base body are integrally formed. The upper end and the lower end of the side wall are connected with the edge of the upper cover and the edge of the base body respectively. The upper cover, the side wall and the base body are all made of metal. The invention further discloses a manufacturing method of the metal base of the cooling fan. As the structure is integrally formed through stamping, made of metal and composed of the upper cover, the side wall and the base body, the metal base is simple in structure, convenient to machine and good in cooling performance due to the fact the a shell is thin.

Description

technical field [0001] The invention relates to the technical field of heat dissipation equipment, in particular to a metal base of a heat dissipation fan and a manufacturing method thereof. Background technique [0002] There are many types of radiators in our daily life. There are laptop radiators, car radiators, and more. The chip of the CPU is usually less than 2 square centimeters, but the power consumption reaches tens or hundreds of watts. If the heat cannot be conducted in time, once the heat accumulates in the chip, it will cause serious consequences for the radiator. , for the radiator, the most important thing is that its base can absorb the heat released by the CPU as much as possible in a short time, that is, the instantaneous heat absorption capacity, which can only be done by metals with high thermal conductivity. For metal thermally conductive materials, specific heat and thermal conductivity are two important parameters. [0003] Existing radiators are mo...
