Definitions
- the present invention relates to an arithmetic processing unit having an air cooling mechanism using a cooling fan.
- Natural cooling is an old cooling method that can be realized with a simple mechanism, but has little cooling effect.
- Forced cooling is a method in which wind is generated by the rotation of the fan and the cooling effect is enhanced, but the mechanism becomes complicated as much as the fan is required.

- the cooling air flowing in the blade server flows while taking heat from the heating element on the flow path, so that the air temperature gradually increases due to the heat. Therefore, a cooling effect is high in a blade portion to which fresh air is applied, and a cooling effect is reduced in an input / output portion to which cooling air that has been heated to remove heat from the blade portion is applied. In recent years, the amount of heat generated at the input / output section tends to increase, and it is difficult to cool by the conventional methods.
