Description

Technical Field

[0001] This utility model relates to the field of data center technology, specifically to an automatic coolant filling device for data center liquid cooling systems. Background Technology

[0002] With the rapid development of information technology, the scale and computing power of data centers are constantly increasing, and the power density of single racks is continuously growing. Against this backdrop, liquid cooling technology has become a key means to solve the heat dissipation problem of data centers, with immersion, spray, and cold plate liquid cooling methods being widely used. Timely replenishment of coolant is crucial during the operation of a liquid cooling system.

[0003] However, existing automatic filling equipment lacks the function of filtering coolant during actual use. This can cause the data center liquid cooling system to malfunction due to impurities during coolant filling, making it inconvenient for users. Therefore, we propose an automatic coolant filling device for data center liquid cooling systems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic coolant filling device for data center liquid cooling systems, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic coolant filling device for a data center liquid cooling system, comprising a base plate, a liquid storage tank fixedly connected to the top left side of the base plate, a fixing plate fixedly connected to the top of the outer side of the liquid storage tank, a motor fixedly connected to the inner side of the fixing plate, a threaded rod fixedly connected to the output end of the motor, a cleaning mesh plate threadedly connected to the surface of the threaded rod, a base fixedly connected to the middle of the bottom of the liquid storage tank, and a filter screen cylinder threadedly connected to the inner cavity of the base.

[0006] Preferably, the top of the liquid storage tank is movably connected to a first movable cover plate and a second movable cover plate. The top of the first movable cover plate and the second movable cover plate are fixedly connected to a fixing block. The inner cavity of the fixing block is threaded with a limit rod. The top of the first movable cover plate and the second movable cover plate are fixedly connected to a handle. The top of the second movable cover plate is fixedly connected to an alarm. The top of the first movable cover plate is fixedly connected to a liquid inlet pipe.

[0007] Preferably, a data center liquid cooling device body is fixedly connected to the right side of the top of the base plate, and an infusion pump is fixedly installed on the top of the data center liquid cooling device body by bolts. A suction pipe is fixedly connected to the inlet end of the infusion pump, and a flow meter is provided on the surface of the suction pipe. The outlet end of the suction pipe is connected to one side of the top of the data center liquid cooling device body through a pipe.

[0008] Preferably, a second liquid level sensor is fixedly installed at the bottom left side of the liquid storage tank by bolts, and the output end of the second liquid level sensor is unidirectionally electrically connected to the input end of the alarm.

[0009] Preferably, a display is fixedly connected to one side of the data center liquid cooling device body by bolts, and a first liquid level sensor is fixedly installed at the bottom right side of the data center liquid cooling device body by bolts.

[0010] Preferably, a microcontroller is fixedly installed at the middle of the top of the data center liquid cooling device body by bolts, and the output end of the microcontroller is unidirectionally electrically connected to the input end of the motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a base and filter screen inside the liquid storage tank to perform preliminary filtration of the coolant and remove larger particulate impurities. At the same time, the motor-driven threaded rod inside the fixed plate moves the cleaning screen plate within the liquid storage tank to achieve secondary cleaning and filtration of the coolant. This effectively prevents impurities from entering the liquid cooling device body of the data center, avoids clogging pipes or affecting heat dissipation performance, extends the service life of the equipment, and facilitates the cleaning of impurities filtered by the cleaning screen plate.

[0013] 2. This utility model connects the data center liquid cooling unit body on the top right side of the base plate with a liquid pump at the top. The inlet end of the liquid pump is connected to a suction pipe to draw coolant from the storage tank, and the outlet end delivers it to the liquid cooling unit body. When the liquid level inside the data center liquid cooling unit body is monitored by a first liquid level sensor, if it is lower than a set value, the microcontroller controls the liquid pump to start, realizing automatic coolant replenishment. This greatly reduces manual intervention, improves the efficiency of data center coolant replenishment, and ensures the stable operation of the liquid cooling system. The first liquid level sensor on the data center liquid cooling unit body monitors the internal liquid level in real time and transmits the data to the display. The display is for staff to view; the second liquid level sensor at the bottom left of the liquid storage tank monitors the liquid level. When the liquid level is too low, it sends a signal to the alarm to trigger an alarm, reminding staff to replenish the coolant in time to avoid equipment failure due to insufficient coolant and ensure the safe and stable operation of the data center. The first and second movable covers on the top of the liquid storage tank, together with the fixing block and limit rod, make it convenient for staff to open the covers to clean the inside of the liquid storage tank, replace the filter screen, and perform other maintenance operations. The handle design on the cover makes it easy to open and close. The overall structure is reasonably designed, easy to operate, and reduces maintenance difficulty and cost.
