Thermal dissipation system for server

A thermal dissipation system for a server includes a compressed air generating device, a compressed air transmission device, and a controller coupled to the compressed air generating device and the compressed air transmission device. The compressed air generating device includes at least one compressed air source for outputting compressed air. The compressed air transmission device is coupled to the compressed air generating device, and is configured to transmit the compressed air to a server, to make the temperature of air inside the server can be outputted with the compressed air. The controller is configured to detect the heat in the server through the compressed air transmission device, and control values of the pressure and airflow of the compressed air output from the compressed air generating device, according to the heat detected of the server. Therefore, the thermal dissipation system can output compressed air with higher pressure and greater airflow.

FIELD

Heat dissipation of servers usually depends on fans or water-cooling, which will result in higher cost, greater noise, higher temperature of environment of server, and damage to hard disk drives.

DETAILED DESCRIPTION

The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently coupled or releasably coupled. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.

The disclosure will now be described in relation to a thermal dissipation system.
