Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation fans, in particular to a computer heat dissipation fan which is convenient to disassemble and assemble. Background Art

[0002] Computer fans are also called cooling fans, which are generally used for heat dissipation. They are provided for use in radiators and chassis. The sizes of general cooling fans on the market range from 2.5cm to 30cm in diameter, and the thickness ranges from 6mm to 76mm. According to different operating requirements, rare AC (alternating current, powered by household sockets) and common D power supplies (direct current, powered by computer adapters or motherboards) can be used. Most of them use two-phase motors (two sets of copper coils, a total of four units), which is conducive to saving production costs when the speed is not high. When installing the existing cooling fan, the fan body is installed in the computer case, and the wiring port is connected to the case. The connection between the wiring port and the case is usually clamped. When disassembling, excessive force may cause damage to the wiring port, thereby increasing the difficulty of disassembly and assembly. At the same time, it may cause the wiring port to loosen, resulting in poor contact at the connection and damage. Utility Model Content
