Description

Wind hood and computer host

technical field

The utility model relates to a wind guide cover and a computer host.

Background technique

A computer mainly has components such as a casing, a power supply, a mainboard, a central processing unit, a display card, an interface card, and a random access memory, and most of the aforementioned components are installed in the casing.

Since the computing power of the graphics processor of the current display card is also very powerful, its power consumption also increases continuously with the computing power. At present, most of the graphics processors of the graphics cards are usually equipped with heat dissipation devices, such as heat sinks and/or fans, to assist in dissipating the heat generated by the graphics processors.

However, a poor cooling device cannot dissipate the heat generated by the graphics processor, causing the heat energy in the graphics processor to accumulate and cause its temperature to rise. If it is slight, the graphics processor may produce some errors in the process of processing data or displaying graphics, and if it is serious, it may It will cause the graphics card to not work properly and cause the computer to freeze, that is, the computer cannot operate stably.

In addition, even if the cooling device is operating normally, the temperature of the air at the cooling discharge end is still high, which still makes it impossible to discharge the heat generated by the heat source. Therefore, if the relatively low-temperature air can be directed towards the graphics card or other heat sources, it will enhance the heat dissipation effect and make the computer run more stably.

In addition, if the accessories for guiding the low-temperature air can be selectively and easily assembled in the main computer by the user, it will be more convenient to expand or optimize the cooling system of the computer.
