[0052] Embodiment 2

[0053] In the preferred embodiment 2 of the present application, a degassing device control method is provided, which is applied to the degassing device in the above-mentioned embodiment 1. Specifically, Figure 2 An optional flow chart of the method is shown in Figure 2 , which comprises the following steps S202-S208:

[0054] S202: detecting whether the degassing device meets the degassing condition;

[0055] S204: controlling the degassing device to perform degassing when the degassing condition is met;

[0056] S206: judging whether the liquid cooling system needs to be supplemented with liquid after the degassing is completed;

[0057] S208: controlling the degassing device to supplement the liquid cooling system with liquid when the liquid cooling system needs to be supplemented with liquid.

[0058] In the above-mentioned embodiments, a degassing device of a liquid cooling system is provided, which separates the gas and liquid by adding a degassing filter screen to the degassing device to degas the liquid to be degassed entering the degassing device, thereby realizing liquid degassing. For the high-viscosity liquid of the liquid cooling system, the viscosity of the liquid can be effectively reduced, the structure is simple, the cost is low, the vibration of the whole water pipeline and components is reduced, the cavitation is reduced, the lift and flow of the water pump are improved, and the usability and reliability of the liquid cooling system are effectively improved.

[0059] The gas removal condition at least includes one of the following: reaching a regular opening time of the gas removal device, and reaching a preset pressure threshold of the system pressure when the liquid cooling system is initially filled with liquid; that is, the timing of opening the gas removal device is when the system is initially started and periodically during the system operation after starting, so that the liquid after gas removal is used to supplement the liquid when the system needs to be supplemented.

[0060] controlling the gas removal device to remove gas, including:

[0061] controlling the liquid inlet valve to open, and simultaneously controlling the heating belt to heat the liquid to be removed to a preset liquid inlet temperature before entering the liquid inlet;

[0062] controlling the heating device to open, and heating the liquid to be removed to a preset heating temperature;

[0063] controlling the liquid inlet valve to close when the liquid level in the gas removal device reaches a preset high liquid level, and controlling the heating belt to close;

[0064] controlling the heating device to close after the heating belt is closed for a first preset time;

[0065] determining that the gas removal is completed after the heating device is closed for a second preset time.

[0066] Specifically, controlling the heating device to open includes: controlling the first heating section and the third heating section to open; detecting the liquid level in the gas removal device, and controlling the second heating section to open and the third heating section to close when the liquid level in the gas removal device reaches the position of the second heating section.

[0067] The above process is a gas removal process:

[0068] The gas removal device has a one-way automatic exhaust valve at the top, the liquid inlet valve is located at the upper part of the gas removal device, the pipeline connected to the liquid inlet valve directly extends into the interior of the gas removal device, and a spraying device is additionally arranged, and the water sprayed out is in a mist state. A mesh gas removal wire mesh is arranged 15-20 cm below the gas removal spray head.

[0069] A heating element is installed at the bottom of the gas removal device (below the low liquid level switch), gas is precipitated and moves upward by heating the liquid, and is finally discharged out of the system through the exhaust valve. Note that the power of the heating element should not be too large, and it can help to quickly precipitate gas.

[0070] The gas removal process is a regular opening function associated with the running time of the water pump.

[0071] When the water pump is initially opened, the liquid supplement valve is opened and the liquid pump is started after running for T1 hours (which can be set according to the size of the water system), the liquid in the gas removal device is pumped into the water main, and the liquid pump and the liquid supplement valve are closed when the liquid in the gas removal device reaches the low liquid level switch.

[0072] Open the liquid inlet valve, and let the water system main pipeline liquid spray into the degassing device in the form of mist. A mesh degassing wire mesh is arranged 15-20 cm below the spray head. The wire mesh is 2-4 layers of cross-shaped stainless steel wire mesh. The water / glycol is first discharged from the spray head when it is sprayed in the form of mist, and the gas mixed therein is discharged. When the sprayed water / glycol passes through the degassing wire mesh, the wire mesh further cuts the liquid drops, and the internal bubbles are broken, so that secondary degassing is realized.

[0073] The water / glycol that has undergone secondary degassing drops to the bottom of the degassing device.

[0074] When the liquid in the degassing device reaches the high liquid level switch, the liquid inlet valve is closed. The liquid is preheated by the electric heating element during the standing time T2 (1h≤T2≤2h), the gas rises and is continuously discharged through the exhaust valve. After the standing is completed, the heating element is turned off. After the standing is completed, the liquid supplement valve and the water pump are turned on, the water in the degassing device is pumped to the main liquid supply pipeline, the liquid level falls to the low liquid level switch, and the liquid supplement valve and the water pump are turned off, and one cycle of degassing is completed.

[0075] The pipeline is wound with a pipeline heating belt after the liquid inlet valve, and an electric heating element is arranged in the degassing device (the position is at the bottom).

[0076] Heating belt and electric heating control strategy (the water temperature of the water system is 25℃-35℃, and this temperature is the liquid supply temperature of most liquid cooling equipment):

[0077] 1. When the liquid inlet valve is opened, the heating belt and the electric heating element are turned on at the same time. The heating belt raises the temperature of the liquid before the nozzle to 40℃-50℃, so as to reduce the viscosity of the liquid (usually glycol) and improve the atomization effect.

[0078] 2. After the electric heating element in the degassing device is turned on, the temperature in the degassing device is maintained at 60℃-70℃, so as to further reduce the viscosity of the liquid, make the bubbles contained in the liquid broken due to the temperature rise, and the internal gas can be easily separated out.

[0079] 3. After the liquid inlet valve is closed, the pipeline heating belt is turned off first, and the electric heating element is still turned on.

[0080] 4. After standing for 10-30 minutes, the electric heating element is turned off. At this time, the gas in the liquid in the degassing device has been separated out and discharged through the exhaust valve at the top.

[0081] 5. After the electric heating element is turned off, the temperature of the liquid in the degassing device gradually decreases during the subsequent standing time. When the liquid supplement valve and the water pump are turned on, the temperature in the degassing device is not much different from the water temperature of the water system. At this time, the liquid in the degassing device is supplemented into the system, and the temperature fluctuation of the water system is not caused.

[0082] In addition, the electric heating can also adopt N-segment type, taking three-segment type as an example, which is arranged at the bottom, middle and upper part of the degassing tank respectively, and is defined as D1-D3 from bottom to top, and control adopts segmented control.

[0083] 1. When the liquid inlet valve is opened, the heating belt, D1 and D3 are opened, at this time, D1 heats the liquid in the tank, and D3 heats the mist liquid sprayed by the nozzle;

[0084] 2. When the liquid level rises to D2, D2 is automatically opened, and D1 and D2 heat the liquid in the tank;

[0085] 3. When the liquid inlet valve is closed, the liquid spraying is stopped, and the heating belt is closed;

[0086] 4. After standing for 10-30 minutes, D1-D3 are all closed.

[0087] In addition, the internal electric heating of the degassing tank can only keep D3 or keep none, and the pipeline heating belt is wound outside the degassing tank, and the heating power is constant, during the opening and running of the unit, the heating belt is always opened, so that the degassing tank is always kept at 50-60℃,

[0088] During the subsequent unit operation, the degassing cycle is opened once every T3 (T2+1≤T3≤T2+3) hours.

[0089] When the water system water temperature is-40℃≤water system water temperature<25℃, the electric heating is closed after standing for 1-2 hours, the standing time T2 is extended by 2 hours, and the interval time T3 is controlled according to the current T2.

[0090] In a preferred embodiment of the present application, determining whether the liquid cooling system needs to be supplemented with liquid includes: detecting the return liquid pressure of the liquid return pipe of the liquid cooling system; determining whether the return liquid pressure is less than a first preset pressure; if yes, determining that the liquid cooling system needs to be supplemented with liquid, otherwise, determining that the liquid cooling system does not need to be supplemented with liquid.

[0091] In addition, after the liquid cooling system is supplemented with liquid by the degassing device, the method further includes: re-detecting the return liquid pressure; determining whether the return liquid pressure is greater than a second preset pressure; wherein the second preset pressure is greater than the first preset pressure; if yes, stopping supplementing the liquid cooling system with liquid, otherwise, continuing to supplement the liquid cooling system with liquid.

[0092] The above process is a liquid supplementing process, the return liquid pressure P value of the liquid return pipe of the liquid cooling system is detected, when P

[0093] The ethylene glycol solution is brought into the degassing device through the circulation of the liquid cooling system, the gas and the liquid are separated through a spraying device, the gas enters the top of the degassing device, and the gas is discharged through the exhaust valve, the continuous degassing is realized through the circulation of the water system, and when it is detected that the liquid return pressure is lower than a certain value, the liquid in the degassing device is replenished to the liquid supply system through the opening of the control valve. This system has the functions of liquid adding, liquid replenishing and degassing.
