It can be understood that the specific embodiments described herein are only for explaining the relevant utility model and not for limiting the utility model.

[0024] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0025] Embodiment 1

[0026] Please refer to Figures 1 - 5 , a cooling structure of a circulating water pool provided by the present application includes: a first chiller 9, a first cooling tower 11, a second cooling tower 12, and a circulating water pool 8;

[0027] The circulating water pool 8 stores circulating water;

[0028] The first chiller 9 has a first inlet and a first outlet, and the first inlet and the first outlet are respectively connected to the circulating water pool 8; the circulating water circulates between the circulating water pool 8 and the first chiller 9; the first chiller 9 has a second inlet and a second outlet, and the second inlet and the second outlet are respectively connected to the output port and the input port of the first cooling tower 11; cooling water circulates between the first cooling tower 11 and the first chiller 9; the first chiller 9 is used to cool the circulating water; the first cooling tower 11 is used to dissipate heat from the cooling water;

[0029] The input port and the output port of the second cooling tower 12 are respectively connected to the circulating water pool 8; circulating water circulates between the second cooling tower 12 and the circulating water pool 8; the second cooling tower 12 is used to cool the circulating water.

[0030] Specifically, the first chiller has an evaporator, a compressor, a throttle valve, and a condenser; the refrigerant gas obtained after being compressed by the compressor is a high-temperature and high-pressure refrigerant gas, and the high-temperature and high-pressure refrigerant gas enters the condenser to exchange heat with the cooling water from the first cooling tower 11 to obtain a low-temperature and high-pressure refrigerant liquid, and then enters the throttle valve for throttling and pressure reduction to form a low-temperature and low-pressure refrigerant liquid, and then enters the evaporator to exchange heat with the circulating water from the circulating water pool 8 to cool the circulating water; the temperature of the cooling water rises after exchanging heat with the high-temperature and high-pressure refrigerant gas in the condenser, and then enters the first cooling tower 11 to dissipate heat.

[0031] The effective heat dissipation of the first cooling tower ensures that the refrigerant can be condensed at a lower temperature, which helps to improve the effect of the entire refrigeration system, because the condensation pressure of the refrigerant is lower at a lower temperature, and the energy consumption of the compressor will also be reduced accordingly;

[0032] Working principle: As Figure 2As shown in the figure, the present application includes: a circulating water tank 8, a first chiller 9, a first cooling tower 11, and a second cooling tower 12. The circulating water tank 8 is respectively connected to the first chiller 9 and the second cooling tower 12, such that the circulating water forms two loops respectively between the circulating water tank 8 and the first chiller 9, and between the circulating water tank 8 and the second cooling tower 12. Both the first chiller 9 and the second cooling tower 12 cool the circulating water; compared with Figure 5 in the prior art shown in the figure where the circulating water is cooled only by a chiller, the present application can not only cool the circulating water through the first chiller 9, but also use the ambient temperature to dissipate heat from the circulating water through the second cooling tower 12, thereby reducing the running time of the first chiller 9, reducing the power consumption of the first chiller 9, and further avoiding waste of energy.

[0033] In some embodiments, a second chiller 10 is further provided. The second chiller 10 has a third inlet and a third outlet, and the third inlet and the third outlet are respectively connected to the circulating water tank 8, and the circulating water circulates between the circulating water tank 8 and the second chiller 10; the second chiller 10 has a fourth inlet and a fourth outlet, and the fourth inlet and the fourth outlet are respectively connected to the output port and the input port of the first cooling tower 11, and cooling water circulates between the second chiller 10 and the first cooling tower 11; the second chiller 10 is used to cool the circulating water.

[0034] Specifically, in summer, since the temperature of the circulating water is relatively high, when there is only one chiller, the chiller needs to be set to high-power operation to cool the circulating water to the specified temperature, but this will cause higher power consumption; therefore, in the present application, the cooling structure further includes a second chiller 10, and circulating water circulates between the second chiller 10 and the circulating water tank 8, and cooling water circulates between the second chiller 10 and the first cooling tower 11;

[0035] The second chiller has an evaporator, a compressor, a throttle valve, and a condenser; the refrigerant is compressed by the compressor to obtain a high-temperature and high-pressure refrigerant gas. The high-temperature and high-pressure refrigerant gas enters the condenser to exchange heat with the cooling water from the first cooling tower 11 to obtain a low-temperature and low-pressure refrigerant liquid, and then enters the throttle valve for throttling and pressure reduction to form a low-temperature and low-pressure refrigerant liquid, and then enters the evaporator to exchange heat with the circulating water from the circulating water tank 8 to cool the circulating water; the temperature of the cooling water rises after exchanging heat with the high-temperature and high-pressure refrigerant gas in the condenser, and then enters the first cooling tower 11 for heat dissipation.

[0036] Since two chillers work simultaneously in the present application, both chillers continuously operate within the best efficiency range to reduce the power consumption during use, and further avoid waste of energy.

[0037] In some embodiments, the input port of the first cooling tower 11 is connected to the input port of the second cooling tower 12 through a first pipeline 13; the output port of the first cooling tower 11 is connected to the output port of the second cooling tower 12 through a second pipeline 14; a first control assembly is provided on the first pipeline 13 and the second pipeline 14, and the first control assembly is used to control the on-off of the first pipeline 13 and the second pipeline 14; the input port of the second cooling tower 12 is connected to the circulating water tank 8 through a third pipeline 15, and a fourth control assembly is provided on the third pipeline 15, and the fourth control assembly is used to control the circulating water tank 8 to supply circulating water to the second cooling tower 12; the second pipeline 14 is connected to the circulating water tank 8 through a fourth pipeline 16, and a fifth valve 5 is provided on the fourth pipeline 16, and the fifth valve 5 is used to control the on-off between the output port of the second cooling tower 12 and the circulating water tank 8.

[0038] Specifically, the input port of the first cooling tower 11 is connected to the input port of the second cooling tower 12 through a first pipeline 13; the output port of the first cooling tower 11 is connected to the output port of the second cooling tower 12 through a second pipeline 14; a first control assembly is provided on the first pipeline 13 and the second pipeline 14 to respectively control the on-off of the first pipeline 13 and the second pipeline 14; in some embodiments, the first control assembly includes a third valve 3 and a fourth valve 4, the third valve 3 is provided on the first pipeline 13 and is used to control the on-off of the first pipeline 13; the fourth valve 4 is provided on the second pipeline 14 and is used to control the on-off of the second pipeline 14;

[0039] Meanwhile, the input port of the second cooling tower 12 is connected to the circulating water tank 8 through a third pipeline 15, and a fourth control assembly is provided on the third pipeline 15 to control the circulating water tank 8 to supply circulating water to the second cooling tower 12; the second pipeline 14 is connected to the circulating water tank 8 through a fourth pipeline 16, and a fifth valve 5 is provided on the fourth pipeline 16, and the fifth valve 5 is used to control the on-off between the output port of the second cooling tower 12 and the circulating water tank 8; in some embodiments, the fourth control assembly includes: a water pump 7 and a sixth valve 6, the water pump 7 is used to transport the circulating water in the circulating water tank 8 to the second cooling tower 12, and the sixth valve 6 is used to control the on-off of the third pipeline 15;

[0040] Specifically, such as Figure 3As shown, when it is winter, the ambient temperature is relatively low, and the purpose of cooling the circulating water can be achieved only by the ambient temperature, without the need to use a chiller to cool the circulating water. Therefore, at this time, both the first chiller 9 and the second chiller 10 are in the off state, thereby reducing power consumption. When in use, open the third valve 3, the fourth valve 4, the fifth valve 5 and the sixth valve 6. At this time, the input port of the first cooling tower 11 is connected to the input port of the second cooling tower 12, the output port of the first cooling tower 11 is connected to the output port of the second cooling tower 12, the output port of the second cooling tower 12 is connected to the circulating water tank 8, and the circulating water tank 8 is connected to the input port of the second cooling tower 12. Then turn on the water pump 7. The circulating water flows from the circulating water tank 8 to the input port of the second cooling tower 12, and flows from the first pipeline 13 to the input port of the first cooling tower 11, and enters the first cooling tower 11 and the second cooling tower 12 for heat dissipation and cooling. After the heat dissipation is completed, the circulating water in the second cooling tower 12 returns to the circulating water tank 8 through the fourth pipeline 16. The circulating water in the first cooling tower 11 returns to the circulating water tank 8 via the second pipeline 14 and the fourth pipeline 16.

[0041] In some embodiments, the second pipeline 14 is also connected to the second inlet and the fourth inlet.

[0042] Specifically, as Figure 4 shown, when it is summer, the external ambient temperature is too high to cool the circulating water tank through the second cooling tower 12. Therefore, both the first cooling tower 11 and the second cooling tower 12 are used to dissipate the heat of the cooling water in the first chiller 9 and the second chiller 10, ensuring that both the first chiller 9 and the second chiller 10 operate in the optimal efficiency range, thereby reducing power consumption.

[0043] When in use, close the fifth valve 5 and the sixth valve 6, open the third valve 3 and the fourth valve 4, and at the same time turn on the first chiller 9 and the second chiller 10. At this time, there is circulating water flowing between the circulating water tank and the first chiller 9 and between the circulating water tank and the second chiller 10. The refrigerant in the first chiller 9 and the second chiller 10 cools the circulating water. The cooling water that exchanges heat with the refrigerant flows to the input port of the first cooling tower 11 and flows from the first pipeline 13 to the input port of the second cooling tower 12, and then enters the first cooling tower 11 and the second cooling tower 12 for heat dissipation. After the heat dissipation is completed, the circulating water in the second cooling tower 12 returns to the first chiller 9 and the second chiller 10 through the second pipeline 14, and the circulating water in the first cooling tower 11 returns to the first chiller 9 and the second chiller 10 from the output port.

[0044] In some embodiments, both the first cooling tower 11 and the second cooling tower 12 have two input ports and output ports; the two input ports of the first cooling tower 11 are respectively provided with a first valve 1; the two input ports of the second cooling tower 12 are respectively provided with a second valve 2.

[0045] Specifically, as Figure 1 shown, both the first cooling tower 11 and the second cooling tower 12 have two input ports and output ports to enhance the input and output speeds of the first cooling tower 11 and the second cooling tower 12; meanwhile, the two input ports of the first cooling tower 11 are respectively provided with first valves 1 to control the opening and closing of the first cooling tower 11; the two input ports of the second cooling tower 12 are respectively provided with second valves 2 to control the opening and closing of the second cooling tower 12.

Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
