Problems solved by technology
[0004] However, the temperature detected by the NTC temperature sensor is transmitted to the NTC temperature sensor by heat sources such as MOS tubes and transformers through the medium, and the temperature spreads slowly in the medium. For example, when the NTC receives 50°C, the heat source has reached 60°C, which leads to hysteresis in the heat dissipation strategy

The invention discloses a thermal management method for a PSU, and the method comprises the steps: determining a temperature change curve of each heating part of the PSU in a process that the PSU enters the working condition from a non-working state until the temperature is stable according to each working condition of the PSU; the temperature value of each heating component in the operation process of the PSU is detected; and when it is judged that the temperature value of the heating component after the first duration exceeds a temperature early warning threshold value corresponding to the heating component based on the current temperature value of any heating component and the temperature change curve of the heating component under the current working condition, the heat dissipation intensity of the fan is increased according to a preset fan control rule. By applying the scheme of the invention, the condition that the PSU is overheated can be effectively avoided. The invention further provides a server and a thermal management system of the PSU of the server, and the thermal management system has the corresponding technical effects.
Description
technical field [0001] The present invention relates to the technical field of temperature control, and in particular, to a thermal management system and method for a server and its PSU. Background technique [0002] The power supply will generate heat when working, and the continuous temperature rise will cause changes in performance, which may eventually lead to system failure, and overheating can easily shorten the life of components and affect the reliability of the system. [0003] The thermal problem is the bottleneck of the current PSU (Power Supply Unit, power supply) design, which limits the development of the PSU, and is not conducive to the development trend of the miniaturization and high power of the PSU. Most PSUs at this stage achieve heat dissipation in the form of convection and air cooling, and receive the internal temperature of the PSU detected in real time by the NTC (NegativeTemperature Coefficient, negative temperature coefficient) temperature sensor t...
