The scale is generally a precipitate of calcium carbonate and magnesium hydroxide, so that the cleaning agent can use weak acid, such as diluted formic acid or citric acid, and the like, and can be added with proper amount of surfactant and buffer. The position of the cleaning inlet and outlet can be separated into two disconnectable interfaces at any pipeline of the cooling liquid loop according to actual conditions, and the interfaces are connected during the working of the liquid cooling unit and disconnected into two interfaces during the cleaning.
Before cleaning, all valves in the cooling liquid loop are kept in an open state, and the cooling liquid in the pipeline of the liquid cooling unit is discharged by opening the ball valve 1. After the cooling liquid is discharged, the first electromagnetic valve 5 and the third electromagnetic valve 9 are closed, the second electromagnetic valve 6 is opened, and the cleaning agent flows into the cooling liquid loop from the cleaning agent liquid storage tank 7 under the action of the water pump 12, and at the moment, the liquid heater 14 is opened to heat the cleaning agent. When the water immersion sensor 4 detects that liquid passes, the cleaning agent is stopped after the cleaning agent is continuously poured for a certain period of time (or the cleaning agent is stopped after the cleaning agent is continuously poured without setting the water immersion sensor 4 to directly set a preset time, the water immersion sensor 4 and a time relay can be operated manually or used for controlling the on-off of the second electromagnetic valve 6 and the first electromagnetic valve 5 in a matched mode), when the time for stopping pouring is reached, the second electromagnetic valve 6 and the third electromagnetic valve 9 are closed, the first electromagnetic valve 5 is opened, the operation of the water pump 12 is stopped, the cleaning agent is soaked in a cooling liquid loop for 1-2 hours, the liquid heater 14 continuously works, and the cooling liquid is kept in a temperature range of 40 ℃. After the soaking is completed, the water pump 12 is started, the heater continuously heats the flowing cleaning agent, and part of impurities are filtered under the action of the filter 2 to carry out the cleaning process. After the cleaning is finished, the cleaning agent is discharged through the ball valve 1. After the cleaning agent is discharged, the first electromagnetic valve 5 and the second electromagnetic valve 6 are closed, the third electromagnetic valve 9 is opened, and clean water flows into the cooling liquid loop from the clean water liquid storage tank 10 under the action of the water pump 12. When the water immersion sensor 4 detects that liquid passes, the cleaning agent is stopped after the cleaning agent is continuously poured for a certain period of time (or the cleaning agent is stopped after the continuous pouring of the clean water is ensured without setting the water immersion sensor 4 to directly set a preset time, the water immersion sensor 4 and a time relay are particularly operated manually or matched to control the on-off of the first electromagnetic valve 5 and the third electromagnetic valve 9), when the time for stopping pouring is reached, the second electromagnetic valve 6 keeps to be closed, the third electromagnetic valve 9 is closed, the first electromagnetic valve 5 is opened, the water pump 12 is continuously operated, and part of impurities are filtered under the action of the filter 2. The PH value detector detects the PH value of the liquid in real time, until the PH value of the liquid is larger than 6, the water pump 12 stops working (or the cleaning agent is estimated to be neutralized by the clean water without setting the PH value detector for a preset time), and the ball valve 1 is opened to discharge the liquid.
Because the scale is generally calcium carbonate and magnesium hydroxide precipitate, can be cleaned by a cleaning agent, and meanwhile, the temperature of the cleaning agent is increased by a heater, and the scale is easier to dissolve in the cleaning agent at a higher temperature; in addition, the cleaning agent remained in the pipeline is removed through clean water after the cleaning is finished, so that the residual cleaning agent is prevented from remaining in the pipeline to continuously corrode the inner wall; the interface for the cleaning agent to enter and exit is arranged on the cooling liquid loop in advance, and then the interface is connected through the interface of the cleaning device, so that the detachable and pluggable cleaning device is realized, long-term binding with the liquid cooling unit is not needed, the interface can be connected when the cleaning device is needed, the space is saved, and meanwhile, one cleaning device can sequentially clean a plurality of liquid cooling units, so that the use cost is lower.
In an alternative embodiment, the flow direction of the coolant in the pipe of the coolant circuit is a first direction when the coolant circuit is not connected to the cleaning device, and the pumping direction of the water pump 12 is such that the flow direction of the liquid flowing into the coolant circuit in the pipe of the coolant circuit is opposite to the first direction.
Since the thickness distribution of the scale is generally related to the flow direction of the cooling liquid, the scale near the outlet of the cooling liquid or near the outlet of the cooling liquid pump is generally accumulated to be thinner due to larger impact force, so that the forward flow of the cooling liquid has smaller resistance to the reverse flow, and therefore, the cleaning agent of the embodiment adopts reverse circulation flow relative to the flow direction of the cooling liquid, and is helpful for flushing down the scale by flushing the accumulated thicker scale by the flow.
In a further alternative embodiment, the bypass pipe in which the ball valve 1 is located at the lowest point of the cleaning device, facilitating the evacuation of the liquid.
The disclosure of the embodiments of the present utility model is merely a preferred embodiment of the present utility model, and is merely for illustrating the technical scheme of the present utility model, but not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art will understand that; the technical scheme recorded in the various embodiments can be modified or part of technical features in the technical scheme can be replaced equivalently; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
