Problems solved by technology

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.

Embodiment Construction

[0018] The method for keeping the low noise of the server power supply of the present invention is described in detail as follows with reference to the accompanying drawings:

[0019] 1. Temperature detection circuit:

[0020] The main function is to detect the temperature rise of the temperature sensing point inside the power supply. Generally, the detection point is placed on the radiator close to the +12V rectifier tube, because the power consumed by the main board now accounts for an increased proportion of +12V, and the +12V rectifier Because the selected voltage level of the tube is relatively high and the VF is too large, its power loss and temperature rise are much larger than those of +5V and +3V3 Schottky low-voltage rectifier tubes in actual use; The power consumption of the rectifier accounts for 40%-60% of the power loss of the entire power supply; therefore, detecting the temperature rise near the +12V rectifier can simulate the temperature rise and the maximum t...

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...
