Power supply heat radiation control method and system

Abstract

The invention provides a power supply heat radiation control method and system, and relates to the technical field of heat radiation. The method comprises that real-temperature parameter values corresponding to air inlet and outlet of a power supply are obtained; one real-temperature parameter value is subtracted from the other real-temperature parameter value, a difference result is compared witha preset temperature threshold for adjusting the rotating speed of a fan, and whether the result is lower than the temperature threshold is determined; if YES, the temperature parameter value T1 of the air inlet of the power supply is compared with the temperature parameter value T2 of the air outlet, and the rotating speed of the fan is adjusted; and otherwise, the rotating speed of the fan is increased through one-gear upshift. Effective heat radiation of the power supply is realized, and the problem of high power consumption and high noise, caused by different positions of the power supply, of the power supply fan can be solved effectively.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation, and in particular relates to a power heat dissipation control method and system. Background technique [0002] As a kind of power supply equipment, the power supply itself will convert part of the electric energy into its own heat due to the conversion efficiency. Heat is one of the biggest killers of power equipment life and long-term stable operation. How to effectively dissipate heat and adapt to various application scenarios is a technical problem. [0003] The commonly used power cooling control method is to set a temperature sensor device at the default air inlet position of the main board of the power supply. The power supply itself defines a maximum allowable air inlet temperature T, and at the same time provides 2 gears (one high and one low) fan speed for the internal fan of the power supply. When the inlet air temperature is lower than T, the fan operates at a lower speed; o...
