this article provides a cooling fan fixing device, especially a cooling fan fixing device for a computer host.

computer mainframe is the soul of the computer, because it has some heating elements, such as CPU, so it is extremely important in heat dissipation, especially when the current information products are seeking large capacity and high efficiency, heat dissipation has become a problem that has to be faced.

there is no denying that the current heat dissipation method is based on the so-called "heat dissipation fan", i.e.the heat is removed by blowing air from the fan.therefore, the arrangement of the heat dissipation fan and even its connection with the casing body are worthy of our concern.

in the case of larger mainframe computers, it needs more than one cooling fan, such as power supply, heating element and other elements.in the case of multi-fan setting, if it is separately set, it is even more complicated in assembly and casing design, so , how to fix the cooling fan of the computer mainframe with a simple and convenient design is a topic worthy of our concern.

in view of this, the purpose of this paper is to provide a kind of fan fixing device for computer mainframe, which can make the fixing of heat dissipation fan more convenient, and can effectively save labor no matter in assembly or disassembly and replacement.in particular, its concise design enables the lower cover of mainframe to be frees up more square space, which helps to arrange circuit boards in the computer.

the fan fixing device of the computer host is vertically fixed on the lower cover of the computer host, and is characterized by comprising:a left sheet, which is a metal sheet body and has a through left hole for the heat dissipation fan to be embedded, and a right edge, which is stamped backward to form a section fold to form a horizontal central top sheet, with a central top hole at its end, a horizontal central top sheet at its bottom, a central top hole at its end, and a horizontal central bottom sheet at its bottom. A right sheet is a metal sheet and the right top hole of the right sheet to form the positioning.

two middle plates on the outer side of the middle plate shall be provided with a middle plate slot for fitting into the tenon body protruding from the lower cover.

the left hole and the periphery of the middle hole must be provided with components for the assembly of the heat dissipation fan.

the left piece is embedded with the power supply fan, and the right piece must be provided with a right piece hole for the line to pass through.
