Embodiment approach

[0026] Please refer to image 3 , The preferred embodiment of the heat dissipation control method of the present invention includes the following steps:

[0027] In step S1, the current detection unit 102 detects the current value output by each power output terminal.

[0028] In step S2, the current detection unit 102 obtains the duty ratio of the PWM signal for controlling the fan speed corresponding to the current value output from the power output terminal according to the mapping table 105 stored in the storage unit 104.

[0029] Step S3, output a PWM signal with a corresponding duty cycle to the corresponding fan module according to the result of the mapping table.

[0030] The heat dissipation control system and method described above control the rotation speed of the corresponding fan by obtaining the current value output by the corresponding power output terminal to achieve the purpose of heat dissipation. This also avoids the disadvantage of increasing the manufacturing cost...

Abstract

A heat dissipation control method is applied to multiple server cabinets. Each server cabinet is provided with multiple servers inside, multiple fan modules are used for dissipating heat of the server cabinets. The heat dissipation control method includes the following steps that the value of currents, output to the corresponding server cabinet, of each power source output end is detected; parameters of a corresponding control signal are obtained according to the values of the currents output by the power source output end; the control signal corresponding to the parameters is output to the corresponding fan module. According to the heat dissipation control method, the defect that rotating speed of corresponding fans is controlled through temperature sensors, so that manufacturing cost for the servers is increased is avoided. The invention further provides a heat dissipation control system.

Description

Technical field [0001] The invention relates to a heat dissipation control system and method. Background technique [0002] A server cabinet can accommodate several servers, and several fans are used to dissipate heat from the servers in the server cabinet. The existing heat dissipation control system is to set a temperature sensor in each server to adjust the rotation speed of the corresponding fan by sensing the temperature generated by each server during the operation of the temperature sensor, thereby achieving the purpose of dissipating heat for each server. However, each server needs to be provided with a corresponding temperature sensor, which leads to an increase in the manufacturing cost of the server. Summary of the invention [0003] In view of the above, it is necessary to provide a heat dissipation control system and method that can reduce the manufacturing cost of the server. [0004] A heat dissipation control system applied to several server cabinets, where each se...
