Embodiment Construction

[0027] In order to understand the technical content of the present invention in detail, specific embodiments are given and described as follows in conjunction with the accompanying drawings.

[0028] A control method for a main circulation pump of a water cooling system, such as figure 1 As shown, the main circulation pump control and protection system in this embodiment includes a power supply acquisition module, a sensor, a water cooling system operation data acquisition and processing module, and a main circulation pump control and protection module. The sensors include flow sensors and pressure sensors. The method comprises the steps of:

[0029] (1) The power supply acquisition module collects the power supply voltage data of the main circulation pump in real time, and sends the acquisition result to the main circulation pump control and protection module.

[0030] (2) The water cooling system operation data acquisition and processing module collects the real-time opera...

Abstract

The invention provides a control method for a main circulation pump of a water cooling system, comprising the following steps: adding real-time monitoring of the power supply voltage of the main circulation pump to the control and protection system of the water cooling main circulation pump, when the water cooling system operation data acquisition module monitors the water When the main circulation flow of the cooling system is low, or the inlet valve pressure of the water cooling system is low, the main pump is overcurrent and other fault signals, the cause of the main circulation pump failure can be quickly judged by the power supply voltage. In case of instantaneous power failure, the running state of the main circulation pump can be kept unchanged, reducing the impact of frequent switching of the main circulation pump on the stable operation of the entire water cooling system, and the water cooling system can quickly send a request for the failure of the main circulation pump caused by the abnormal power supply of the main circulation pump outage signal. The invention improves the reliability of the operation of the main circulation pump of the water cooling system, reduces the possibility of frequent switching of the main circulation pump due to the interference of the power supply voltage, can quickly respond to the abnormal situation of the power supply, and effectively improves the operation stability of the water cooling system.

Description

technical field [0001] The invention relates to a control system of a cooling device for high-power electric electronic equipment, in particular to a control method for a main circulation pump of a water cooling system. Background technique [0002] The cooling system in the operation system of high-power power electronic equipment is related to the safe operation and service life of the cooled device, and is a very important supporting equipment. [0003] As the key component of the cooling system, the main circulating water pump has a direct relationship with the stability of the entire water cooling system. A main circulation pump failure switching control method often used in the water cooling system control device is to judge the failure of the main circulation pump according to the low flow rate and low pressure of the main circulation, and directly switch the main circulation pump. When the power supply system of the main circulation pump has a short-term fault distu...
