With the advancement of technology, the progress of computer execution is getting faster and faster, but the temperature generated in the host computer is also getting higher and higher. In order to effectively dissipate the temperature generated in the host computer outside the system to maintain the temperature in the computer Each component operates below the allowable temperature, and a radiator with a larger area is usually attached to the surface of each component that generates temperature, and the heat dissipation effect is increased by means of the radiator.

In addition, because the existing heat sink structure is mostly used on the central processing unit (CPU), and nowadays the heat dissipation problem of the VGA card inside the computer is also increasingly paid attention to. In addition, existing computers need to support the use of multimedia and the rise of game software, etc. The use of various expansion cards will also generate heat sources, especially if the graphics processing chip (chip) on the VGA card is not dissipated. I am afraid that overheating will affect its operation, and the computer casing is a nearly airtight space, and it is easy to produce a result similar to the greenhouse effect because the heat cannot be discharged to the outside.

Existing way at present mainly is to install a fan additionally on the computer case, and described fan is to carry out heat dissipation especially for the graphic processing chip on the VGA card. However, this method not only needs to increase the use of fans, but also easily causes noise due to the excessive use of fans; and if other fans can be used to provide a natural convection effect, it seems that the use of fans can be reduced, and it can also Reduce noise generation.
