this article relates to a computer CPU heat dissipation fan, in particular to a wind shroud type computer CPU heat dissipation fan .

at present, with the rapid development of computer technology, the CPU of the computer, that is, the central processing unit, is increasingly powerful and processing speed is faster and faster, but at the same time, the power of the CPU is also increasing, and the heat production is increasing.in addition, overclocking is prevalent for a while in recent years.therefore, the existing CPU the heat sink has been unable to effectively cool the CPU. At present, due to the shortage of CPU heat dissipation devices, a large amount of heat generated by the CPU is hard to be discharged, which directly affects the working efficiency of the CPU, reduces the stability of the CPU, and is prone to crash.what's more, lead to CPU burn, bring unnecessary economic losses to users.

summary of the invention:

the purpose of this paper is to provide a cooling fan for the CPU of a wind guide cover type computer, which can effectively guide low-temperature air to the CPU and can take away the heat generated by the CPU in the shortest time, thus solving the problem of difficult cooling in the prior art and preventing the CPU from burning down , to avoid unnecessary property losses and meet people's use requirements.

it is realized through the following technical scheme:the air guide cover type computer CPU heat dissipation fan comprises a casing, a cavity is formed in the casing, a fan is arranged in the cavity, a fan power cord is arranged on the fan, the air guide cover is arranged on the fan, a ventilation cavity is arranged in the air guide cover, and the ventilation cavity communicate with the cavity.

for further realization, the following technical scheme can also be adopted:the top surface of the front end of the air guide cover is an arc surface. A fastening card is arranged on the top surface of the tail end of the air guide cover.

the positive effect is that it is equipped with an air guide cover, which can provide an accurate flow direction for the low-temperature air driven by the fan, so that the flowing low-temperature air passes through the surface of the CPU at a high speed and can effectively take away the heat generated by the CPU, thus effectively providing the CPU with cooling, ensure the working efficiency and stability of the CPU, prevent the CPU overheating and crash, and can ensure the safe operation of the CPU is not burned.
