Method for remaining low noise of server power supply

Abstract

The invention provides a method for keeping low noise of a server power supply, which adopts a bilinear temperature controlled radiation mode. Hardware comprises a voltage stabilizing circuit module (1), a sampling circuit 1 module (2), an arithmetic circuit module (3), an executive circuit module (4), a blower starting circuit module (5), a working voltage source module (6), a sampling circuit 2 module (7) and an excess temperature protecting circuit module (8). Based on the modularized flexile design, through the logic relation of each module, the method can achieve low noise of the server power supply, simultaneously has low cost, and is applied to various computer systems, so the method has quite wide development prospect.

Description

technical field [0001] The invention relates to the fields of computers, servers, storage and communication, and in particular to a method for keeping server power supplies low in noise. Background technique [0002] Today, people pay more and more attention to environmental protection and health, and everyone pays more and more attention to the impact of noise on daily life. To eradicate noise, this is of course impossible, only to find ways to reduce and reduce noise. [0003] Since the server system runs 7x24 hours without interruption, it is very necessary to reduce the noise of the server placed in the office. The fan inside the server power supply generally adopts a constant speed method. Since the load of the server is not fully loaded most of the time, it is inevitable to cause high noise and resonance and other phenomena that affect health. Generally, the traditional server power supply mainly has the following disadvantages. One is that it does not have a tempera...

The fan inside the server power supply generally adopts a constant speed method. Since the load of the server is not fully loaded most of the time, it is inevitable to cause high noise and resonance and other phenomena that affect health.

Generally, the traditional server power supply mainly has the following disadvantages. One is that it does not have a temperature control function. This method will definitely bring about problems such as large noise and resonance. PWM temperature control method, but the start-up noise is relatively large, which is not good for users. In addition, the cost is too high, which is also an obstacle restricting this technology.
