[0061] The working principle of this embodiment is now described. When the load suddenly changes, the pressure sensor and the temperature sensor will detect the relevant data and upload it to the controller. After analysis, the controller controls the valve opening of the energy valve 1 to increase.

[0064] A liquid cooling distribution unit in an embodiment of the present application is described above, and a regulation method in an embodiment of the present application is described below. Figure 3 An embodiment of a regulation method in an embodiment of the present application is applied to the above-mentioned liquid cooling distribution unit, wherein the liquid cooling distribution unit includes a heat exchanger, an energy valve and a bypass valve, and the method includes:

[0065] 301. Obtain the real-time heat value of the heat exchanger;

[0066] The real-time calorific value of the heat exchanger is obtained. Specifically, the real-time calorific value can be calculated by an integrator built into the energy valve, or by other calculation methods, which are not limited here.

[0067] 302. Determine whether the real-time calorific value satisfies the condition that it is greater than the first preset calorific value and less than or equal to the second preset calorific value. If so, execute step 303; if not, execute step 304.

[0068] The first preset heat value is smaller than the second preset heat value, and the second preset heat value is the maximum design load of the heat exchanger. The first preset heat value only needs to be smaller than the second preset heat value, and the specific value can be set according to actual needs, which is not limited here.

[0069] 303. Open the energy valve and the bypass valve;

[0070] If the real-time calorific value is greater than the first preset calorific value and less than or equal to the second preset calorific value, the energy valve and the bypass valve are opened. In one embodiment, it takes 28 seconds for the energy valve to be fully opened, and 8 seconds for the bypass valve to be fully opened. The bypass valve has a fast response speed. Based on PID adjustment, the bypass valve can flow coolant through, and the energy valve can also flow through. The bypass valve is used as the initial adjustment, and the energy valve is used as the fine adjustment.

[0071] 304. Open the energy valve and close the bypass valve.

[0072] If the real-time calorific value is not greater than the first preset calorific value and less than or equal to the second preset calorific value, the energy valve is opened and the bypass valve is closed. The valve opening of the bypass valve is zero, and the energy valve selects the valve opening according to the actual situation.

[0073] In the embodiment of the present application, the real-time calorific value of the heat exchanger is first obtained, and then it is determined whether the real-time calorific value satisfies the requirement of being greater than the first preset calorific value and less than or equal to the second preset calorific value. If so, the energy valve and the bypass valve are opened, otherwise, the energy valve is opened and the bypass valve is closed. By judging the real-time calorific value of the heat exchanger, it is determined whether the load changes suddenly. If the real-time calorific value is greater than the first preset calorific value, it means that the load changes suddenly. Then, the energy valve and the bypass valve are opened at the same time to prevent the secondary side liquid supply temperature from fluctuating greatly and ensure the stability of the system.

[0074] See also Figure 4 Another embodiment of a regulation method of an embodiment of the present application is applied to the above-mentioned liquid cooling distribution unit, wherein the liquid cooling distribution unit includes a heat exchanger, an energy valve and a bypass valve, and the method includes:

[0075] 401. Obtain the real-time heat value of the heat exchanger;

[0076] The real-time calorific value of the heat exchanger is obtained. Specifically, the real-time calorific value can be calculated by an integrator built into the energy valve, or by other calculation methods, which are not limited here.

[0077] 402. Determine whether the real-time calorific value satisfies the condition that it is greater than the first preset calorific value and less than or equal to the second preset calorific value. If so, execute step 403; if not, execute step 404.

[0078] The first preset heat value is smaller than the second preset heat value, and the second preset heat value is the maximum design load of the heat exchanger. The first preset heat value only needs to be smaller than the second preset heat value, and the specific value can be set according to actual needs, which is not limited here.

[0079] 403. Open the energy valve and the bypass valve;

[0080] If the real-time calorific value is greater than the first preset calorific value and less than or equal to the second preset calorific value, the energy valve and the bypass valve are opened. In one embodiment, it takes 28 seconds for the energy valve to be fully opened, and 8 seconds for the bypass valve to be fully opened. The bypass valve has a fast response speed. Based on PID adjustment, the bypass valve can flow coolant through, and the energy valve can also flow through. The bypass valve is used as the initial adjustment, and the energy valve is used as the fine adjustment.

[0081] 404. Open the energy valve and close the bypass valve;

[0082] If the real-time calorific value is not greater than the first preset calorific value and less than or equal to the second preset calorific value, the energy valve is opened and the bypass valve is closed. The valve opening of the bypass valve is zero, and the energy valve selects the valve opening according to the actual situation.

[0083] For ease of understanding, the contents of step 401 to step 404 are described by way of example. Assuming that the first preset heat value is Q1, the second preset heat value is Q2, and the real-time heat value is Q, when the load suddenly changes, Q will increase, when Q1<Q<Q2, the energy valve and the bypass valve are opened for adjustment, and when Q<Q1, it indicates that the load has not suddenly changed, and only the energy valve is opened.

[0084] 405. Obtaining a real-time temperature difference value of the coolant at the inlet and outlet of the liquid cooling distribution unit;

[0085] The real-time temperature difference of the coolant at the inlet and outlet of the liquid cooling distribution unit is obtained. Specifically, based on the detection data transmitted by the temperature sensors at various locations in the liquid cooling distribution unit, the controller calculates the real-time temperature difference of the coolant according to the detection data.

[0086] 406. Determine whether the real-time heat value is less than or equal to the second preset heat value and the real-time temperature difference value is greater than or equal to the preset temperature difference value. If so, execute step 409; if not, execute step 410.

[0087] Specifically, the real-time heat value and the real-time temperature difference value are used for comparison. The preset temperature difference value can be set according to actual needs, and is not specifically limited here. If the conditions are met, the valve opening of the energy valve is maintained, and if the conditions are not met, the valve opening of the energy valve is reduced.

[0088] For ease of understanding, steps 405 to 406 are now described by way of example. Assume that the real-time heat value is Q, the real-time temperature difference value is ΔTi, the second preset heat value is Q2, and the preset temperature difference value is ΔTs. When Q>Q2, the valve opening of the energy valve is reduced, and when ΔTi<ΔTs, the valve opening of the energy valve is also reduced, so that Q≤Q2 and ΔTi≥ΔTs. When Q≤Q2 and ΔTi≥ΔTs, the valve opening of the energy valve is maintained.

[0089] 407. Obtain the real-time flow value of the coolant in the liquid cooling distribution unit and the real-time temperature difference value at the inlet and outlet;

[0090] The real-time flow value of the cooling liquid in the liquid cooling distribution unit and the real-time temperature difference value at the inlet and outlet are obtained. The real-time flow value can be obtained by using the flow meter 17 in the liquid cooling distribution unit.

[0091] 408. Determine whether the real-time flow value is less than or equal to the preset flow value, and the real-time temperature difference value is greater than or equal to the preset temperature difference value. If so, execute step 409; if not, execute step 410;

[0092] The preset flow rate value can be set according to actual needs, and is not specifically limited here, and is generally the maximum flow rate value.

[0093] For ease of understanding, the contents of step 407 to step 408 are now described by way of example. Assume that the real-time flow value is qi, the preset flow value is qs, the real-time temperature difference value is ΔTi, and the preset temperature difference value is ΔTs. When qi>qs, the valve opening of the energy valve is reduced. When ΔTi<ΔTs, the valve opening of the energy valve is also reduced so that qi≤qs and ΔTi≥ΔTs. When qi≤qs and ΔTi≥ΔTs, the valve opening of the energy valve is maintained to achieve a small flow and a large temperature difference.

[0094] 409. Maintain the valve opening of the energy valve;

[0095] If the real-time heat value is less than or equal to the second preset heat value and the real-time temperature difference value is greater than or equal to the preset temperature difference value, or the real-time flow value is less than or equal to the preset flow value and the real-time temperature difference value is greater than or equal to the preset temperature difference value, the valve opening of the energy valve is maintained.

[0096] 410. Reduce the valve opening of the energy valve.

[0097] If the real-time heat value is greater than the second preset heat value and / or the real-time temperature difference is less than the preset temperature difference, or the real-time flow value is greater than the preset flow value and / or the real-time temperature difference is less than the preset temperature difference, the valve opening of the energy valve is reduced.

[0098] In this embodiment, real-time values ​​can be obtained based on various sensors and instruments to determine whether there is a sudden load change, large flow and small temperature difference, or load overload, so as to respond accordingly, improve work efficiency, and ensure the stability of the liquid cooling system.
