Description

A cooling device for a computer mainframe

The utility model relates to a cooling device for a computer host.

At present, with the progress of science and technology, the progress of computer technology is faster, and anyone who knows about computers knows that the heart of a computer is what we call the mainframe, and the mainframe is the most important component that determines the speed of computer data calculation. Due to the continuous advancement of computer technology, the processing speed of the mainframe is also constantly improving. I believe everyone knows that the mainframe will generate an operating temperature when it is working, and the level of this operating temperature depends on the voltage and the computing speed of the mainframe. Simple To put it bluntly speaking, a host with a higher voltage and faster computing speed will generate a higher operating temperature, and an excessively high operating temperature will affect the operating speed of the host, or even cause a crash or damage, while the normal operating temperature will Maintaining the normal computing speed of the mainframe can even greatly increase the computing speed of the current mainframe with overclocking function. Therefore, reducing the operating temperature of the mainframe is the primary goal of the computer industry.
