Embodiment Construction

[0018] Usually, in the computer room of the communication system, several equipment boards are working, and the fan frame is provided with several fans for heat dissipation, and the fan frame monitoring board issues a speed regulation command to control the fan speed. In the existing technology, the fan frame monitoring board controls the fan speed according to the ambient temperature in the equipment room, which cannot effectively dissipate heat from each equipment board in the equipment room, and when a heat dissipation alarm occurs on a certain equipment board, the staff usually directly The fans were set to run at full speed, and noise was not a consideration at this time. According to the fan speed required by each device board, the fan frame monitoring board issues a speed regulation command to control the fan speed based on the highest speed, so that noise can be considered while satisfying heat dissipation.

[0019] Please refer to figure 1 As shown, the control devic...

Abstract

This invention discloses a control device and method for controlling the rotation speed of a temperature-controlled fan, in which the control device includes a parameter allocation unit containing the temperature character parameters of the device mono-plate and the lowest and highest rotation speeds of the fan, a temperature process unit for collecting the current temperature of the mono-plates and computing suitable rates of them based on related temperature character parameters, a data merge unit finding out the maximum speed based on the computed speeds, a fan frame monitor plate sending the speed adjusting order based on the maximum speed to control rotation speed of the fan. This method includes: collecting the current temperature of the mono-plates to compute out a suitable speed for each and find out the maximum speed to send the adjusting order with the maximum rotation speed to control the speed of the fan.

Description

technical field [0001] The invention relates to heat dissipation technology, in particular to a control device and a control method for temperature-controlled fan speed in a computer room. Background technique [0002] In the prior art, taking a computer room in a communication system as an example, there are several equipment boards working in the computer room, and several (usually 6) fans in the fan frame are used to dissipate heat. As we all know, the fan speed of the fan frame will affect two aspects: the heat dissipation capability of the device and the noise index. Generally speaking, the faster the fan speed, the better the heat dissipation effect, but the noise will also increase, and may reduce the life of the fan; if the fan speed is low, the noise is relatively small, but it may not meet the heat dissipation requirements . [0003] The current common processing method is: the fan frame monitoring board calculates the fan frame speed according to the temperature...
