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 circulating pump of a water-cooling system. The control method includes following steps: real-time monitoring for the power supply voltage of the main circulating pump is additionally provided in a water-cooling main circulating pump control protection system, and when an operation data acquisition module of the water-cooling system monitors fault signals such as low main circulating flow of the water-cooling system or low inlet-valve pressure of the water-cooling system, and overcurrent of the main pump, and the fault reason of the main circulating pump can be rapidly determined via the power supply voltage. The operation state of the main circulating pump can maintain unchanged in the condition of instantaneous power failure, the influence on stable operation of the whole water-cooling system by frequent switching of the main circulating pump is reduced, and the water-cooling system can rapidly emit a request outage signal for the faults of the main circulating pump caused by abnormal power supply of the main circulating pump. According to the control method, the operation reliability of the main circulating pump of the water-cooling system is improved, the possibility of frequent switching of the main circulating pump due to the interference of the power supply voltage is reduced, rapid response can be made for the condition of abnormal power supply, and the operation stability of the water-cooling system is effectively improved.

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...
