Embodiment Construction
[0010] Accompanying drawing is a kind of specific embodiment of the present invention. The method of realizing heat dissipation according to the current change is characterized in that the traditional power supply is replaced by a digital power supply, and the information such as the current change of the digital power supply is directly transmitted to the substrate management control on the main board by using the power management bus PMBUS of the digital power supply itself. By programming the baseboard management controller BMC, different power consumption data correspond to different feedback values. The feedback value is directly transmitted from the baseboard management controller BMC to the heat dissipation control system, and the heat dissipation control system controls the operation of the fan.
[0011] It replaces the temperature sensor with the change of current to realize the input to the heat dissipation control system. The advantage of this architecture is that t...

The invention relates to a method for realizing heat dissipation according to an electric current change. The method for realizing heat dissipation according to the electric current change is characterized in that a heat dissipation system is controlled according to detected current magnitudes of a power supply, that is, the electric current change inevitably causes a temperature change, the heat dissipation system will implement an active heat dissipation scheme when judging the electric current change, so that the temperature change is minimized, and the hysteresis quality of a traditional heat radiation method that heat dissipation is conducted after a temperature rise is avoided.

Description
technical field [0001] The invention belongs to the field of heat dissipation of computer servers, in particular to a method for realizing heat dissipation according to current changes. Background technique [0002] In the cooling system of servers, many intelligent cooling solutions have been developed and designed, and are well applied to various servers. But now the heat dissipation basis of intelligent heat dissipation is based on the judgment of the temperature. A bad phenomenon brought about by this is that the cooling system will adjust the fan to increase the speed when the temperature of the system has risen, which has obvious hysteresis. Thus causing thermal instability of the system and useless waste of power consumption. Contents of the invention [0003] In order to make up for the defects of the prior art, the present invention provides a simple and practical method for realizing heat dissipation according to the change of current. [0004] The present inv...
