How Does the Server Cases Dissipate Heat?

The main function of the Server Cases is to place and fix various hardware, playing a supporting and protective role. However, a chassis with poorly planned air duct will cause blue screen, crash or even burn the hardware, especially when the power consumption of the graphics card is still increasing significantly.

Most of the existing chassis cooling air ducts can be divided into: horizontal air duct, vertical air duct and three-dimensional air duct. Let's discuss it together!

Horizontal air duct

The development time of horizontal air ducts is much earlier than that of vertical air ducts and three-dimensional airductst. An obvious feature of the large Server Cases is that the front panel or back is equipped with fans to assist the cooling effect of the horizontal air duct.

The horizontal cooling air duct is practical and simple. It is suitable for CPU and video cards when the heat is not very large. But it has an inevitable defect, that is, there is a dead space for heat dissipation.

According to the principle of hot air rising, the heat under the video card is difficult to exhaust. Therefore, this has a certain impact on the graphics card heat dissipation. In this case, the vertical air duct appears. The design of the vertical air ducts has solved the problem that it is difficult for the graphics card to discharge heat, and the overall heat dissipation effect has also been improved.

Vertical air duct

The vertical air duct uses the principle of hot air rising. The air duct does not turn, the heat flow path is short, and the heat dissipation effect is good. One of the most obvious features is that there is a cooling window on the top of the Server Cases. As this chassis can only be produced by a few manufacturers, its price is more expensive than that of horizontal air duct chassis and three-dimensional air duct chassis.

Three-dimensional air duct

A three-dimensional air duct is a combination of a horizontal air duct and a vertical air duct.

The three-dimensional air duct integrates the advantages of the horizontal air duct and the vertical air duct. It can heat the chassis three-dimensional and take care of the heating components.

The most obvious feature of the three-dimensional air duct design is that there are windows on the top, fans on the front panel and back, and heat dissipation holes on the side panel. The design of multiple air inlets ensures the adequate entry of cold air, while the design of multiple air outlets ensures the adequate discharge of hot air, eliminating the dead corner of heat dissipation.

This multi cooling hole design ensures excellent heat dissipation performance of the chassis. The disadvantages are that the number of fans is large, the cost is increased, the noise is large. And the centralized heat dissipation capacity is generally due to more air in and out.
