[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0026] The cooling system according to the embodiment of the present invention is described below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, the cooling system 100 according to the embodiment of the present utility model includes a cooling component 1 and a voltage stabilizing component 2 .

[0028] The cooling assembly 1 includes a circulation pump 11 and a heat exchanger 12. One end of the circulation pump 11 is suitable for communicating with the external device 8 so that the heat exchange medium after cooling the external device 8 flows into the circulation pump 11. The other end of the circulation pump 11 is connected to one end of the heat exchanger 12 so that the heat exchange medium flowing out of the circulation pump 11 exchanges heat with industrial circulating water through the heat exchanger 12 to cool the heat exchange medium. The other end of the heat exchanger 12 is suitable for communicating with the external device 8 so that the heat exchange medium flowing out of the heat exchanger 12 flows into the external device 8 to cool the external device 8. Specifically, Figure 1 As shown, the heat exchanger 12 is a plate heat exchanger, and the inlet of the circulating pump 11 can be connected to the outlet of the cooling channel of the external device 8 (it should be noted that the cooling channel can be a built-in cooling channel of the external device 8, or the heat exchange medium in the external device 8 and the heat exchange medium of the cooling component 1 can be exchanged through the heat exchanger), and the heat exchange medium (for example, cooling water) after cooling the external device 8 flows into the circulating pump 11, and the outlet of the circulating pump 11 is connected to the inlet of the heat exchanger 12, and the heat exchange medium is pumped into the heat exchanger 12 through the circulating pump 11, and the heat exchanger 12 can be passed with industrial circulating water, so that the industrial circulating water exchanges heat with the heat exchange medium through the heat exchanger 12 to cool the heat exchange medium.

[0029] The pressure stabilizing component 2 stores a heat exchange medium with a preset pressure, so that when the pressure of the heat exchange medium flowing out of the circulation pump 11 is less than the preset value, the pressure stabilizing component 2 is connected to one end of the circulation pump 11, so that the heat exchange medium in the pressure stabilizing component 2 flows into the circulation pump 11 to increase the pressure of the heat exchange medium flowing out of the circulation pump 11. Specifically, Figure 1 As shown, the preset pressure can be set according to actual conditions (for example, the preset pressure can be a precise pressure value or a pressure value in the range of P1-P2), and the outlet of the pressure stabilizing component 2 can be connected to the inlet of the circulating pump 11 through a solenoid valve. Thus, when the pressure in the cooling component 1 is lower than the preset value, the solenoid valve opens, allowing the heat exchange medium in the pressure stabilizing component 2 to flow into the circulating pump 11, thereby stabilizing the pressure of the heat exchange medium in the cooling component 1.

[0030] The cooling system 100 of the embodiment of the utility model is provided with a pressure stabilizing component 2. When the pressure of the heat exchange medium inside the cooling component 1 is insufficient, or the heat exchange medium is insufficient, the pressure stabilizing component 2 can provide the heat exchange medium to the cooling component 1 and supplement the pressure of the heat exchange medium in the cooling component 1. Compared with the related art, the stable operation of the cooling component 1 is ensured, and the cooling efficiency of the cooling component 1 is ensured.

[0031] In some embodiments, the pressure stabilizing assembly 2 includes a tank body and an airbag with a contraction function (not shown in the figure), the airbag is arranged in the tank body so that the airbag divides the tank body into a first cavity and a second cavity, the outer circumferential surface of the airbag and the inner circumferential surface of the tank body define a first cavity, the inner circumferential surface of the airbag defines a second cavity, one of the first cavity and the second cavity is suitable for passing gas, and the other of the first cavity and the second cavity is suitable for passing heat exchange medium. When the pressure of the heat exchange medium in the pressure stabilizing assembly 2 is less than a preset pressure, gas is passed into the pressure stabilizing assembly 2 to increase the pressure of the heat exchange medium in the pressure stabilizing assembly 2, and when the pressure of the heat exchange medium flowing out of the circulating pump 11 is less than the preset pressure, one of the first cavity and the second cavity is connected to the other end of the circulating pump 11, so that the heat exchange medium flowing out through one of the first cavity and the second cavity flows into the circulating pump 11.

[0032] Specifically, Figure 1As shown, the gas can be an inert gas (for example, nitrogen), the airbag is arranged in the tank body, and the settings of the first chamber and the second chamber can be set according to actual conditions. For example, gas can be introduced into the first chamber, and heat exchange medium can be introduced into the second chamber. The outlet of the second chamber is connected to the inlet of the circulation pump 11. When the pressure of the heat exchange medium in the second chamber is less than the preset pressure, the airbag is contracted by introducing gas into the first chamber, thereby increasing the pressure of the heat exchange medium in the second chamber until the preset pressure. When the pressure of the heat exchange medium in the pressure stabilizing component 2 is less than the preset value, the heat exchange medium in the second chamber flows into the circulation pump 11, or the heat exchange medium is introduced into the first chamber, the outlet of the first chamber is connected to the inlet of the circulation pump 11, and gas is introduced into the second chamber. When the pressure of the heat exchange medium in the first chamber is less than the preset pressure, the airbag is expanded by introducing gas into the second chamber, thereby increasing the pressure of the heat exchange medium in the first chamber until the preset pressure. When the pressure of the heat exchange medium in the pressure stabilizing component 2 is less than the preset value, the heat exchange medium in the first chamber flows into the circulation pump 11, thereby making the setting of the pressure stabilizing component 2 more reasonable.

[0033] In some embodiments, the cooling system 100 further includes a relief valve 21, which is connected to the other of the first chamber and the second chamber so that the heat exchange medium in the other of the first chamber and the second chamber is discharged through the relief valve 21. Figure 1 As shown, the overflow valve 21 can be set according to actual conditions, for example: when the heat exchange medium is introduced into the first cavity, the overflow valve 21 is connected to the first cavity, and when the heat exchange medium is introduced into the second cavity, the overflow valve 21 is connected to the second cavity. When the cooling medium in the pressure stabilizing component 2 is pressurized, if the liquid level of the cooling medium in the pressure stabilizing component 2 is higher than the preset liquid level of the pressure stabilizing component 2, it can be discharged through the overflow valve 21 to ensure the stability of the liquid level in the pressure stabilizing component 2, or when the pressure stabilizing component 2 needs to be cleaned, the heat exchange medium in the pressure stabilizing component 2 can be discharged through the overflow valve 21.

[0034] In some embodiments, the cooling system 100 further includes a first detection component (not shown in the figure), which is disposed on the voltage stabilizing component 2 and communicates with at least one of the first cavity and the second cavity so that the first detection component detects the pressure in at least one of the first cavity and the second cavity. Figure 1 As shown, the first detection component can be a pressure gauge. The first detection component can be arranged on the outer peripheral side of the tank body and the detection end of the first detection component can be connected to the first cavity and the second cavity according to actual conditions. For example: the detection end of the first detection component is located in the tank body, or the detection end of the first detection component is located in the airbag, or the first detection component has two detection ends for respectively detecting the pressure in the airbag and the tank body, so that the pressure in the voltage stabilizing component 2 is detected by the first detection component.

[0035] In some embodiments, the cooling system 100 further includes a second detection component (not shown in the figure) and a regulating valve 3 .

[0036] The second detection component is disposed in the other of the first cavity and the second cavity so that the second detection component detects the liquid level of the heat exchange medium in the other of the first cavity and the second cavity. Figure 1 As shown, the second detection component is an automatic liquid level control device, and the detection end of the second detection component can be set according to actual conditions. For example, when the heat exchange medium is passed into the first cavity, the detection end of the second detection component can be located in the first cavity; when the heat exchange medium is passed into the second cavity, the detection end of the second detection component can be located in the second cavity, thereby automatically detecting the liquid level of the heat exchange component through the second detection component.

[0037] In some embodiments, the regulating valve 3 is connected to the other of the first chamber and the second chamber. When the second detection component detects that the liquid level of the heat exchange medium is lower than a preset value, the regulating valve 3 is opened to allow the heat exchange medium to flow into the other of the first chamber and the second chamber. When the second detection component detects that the liquid level of the heat exchange medium is higher than the preset value, the regulating valve 3 is closed. Specifically, Figure 1 As shown, the setting of the regulating valve 3 can be set according to actual conditions, the inlet of the regulating valve 3 can be passed into the heat exchange medium, and the outlet of the regulating valve 3 can be set according to actual conditions, for example: when the heat exchange medium is passed into the first cavity, the outlet of the regulating valve 3 is connected to the first cavity, and when the heat exchange medium is passed into the second cavity, the outlet of the regulating valve 3 is connected to the second cavity. When the second detection component detects that the liquid level of the heat exchange medium is lower than the preset value, the regulating valve 3 is opened to allow the heat exchange medium to pass into the pressure stabilizing component 2 through the regulating valve 3 to supplement the heat exchange medium to the pressure stabilizing component 2. When the second detection component detects that the liquid level of the heat exchange medium is higher than the preset value, the regulating valve 3 is closed to stop passing the heat exchange medium into the pressure stabilizing component 2.

[0038] In some embodiments, the cooling system 100 further includes a filter assembly 4, one end of which is adapted to be connected to an external device 8 so that the heat exchange medium after cooling the external device 8 flows into the filter assembly 4 so that the filter assembly 4 filters the heat exchange medium, and the other end of the filter assembly 4 is connected to one end of a circulation pump 11 so that the heat exchange medium after being filtered by the filter assembly 4 flows into the circulation pump 11. Specifically, Figure 1 As shown, the filter assembly 4 can be a filter, the inlet of the filter is connected to the outlet of the external device 8, and the outlet of the filter is connected to the inlet of the circulation pump 11. Thus, the heat exchange medium flowing into the circulation pump 11 is filtered by the filter to remove impurities in the heat exchange medium, thereby preventing the impurities in the heat exchange medium from clogging or damaging the circulation pump 11, thereby ensuring the service life of the circulation pump 11.

[0039] In some embodiments, the cooling system 100 further includes a check valve 5, the two ends of which are respectively connected to the other end of the heat exchanger 12 and one end of the circulation pump 11. When the circulation pump 11 operates normally, the other end of the heat exchanger 12 and one end of the circulation pump 11 are disconnected through the check valve 5. When the circulation pump 11 loses power, the other end of the heat exchanger 12 and one end of the circulation pump 11 are connected through the check valve 5. Specifically, Figure 1 As shown, the inlet of the check valve 5 is connected to the outlet of the heat exchanger 12, and the outlet of the check valve 5 is connected to the inlet of the circulation pump 11. Under normal operating conditions, the inlet pressure of the circulation pump 11 is low, and the check valve 5 is in a closed state. When the circulation pump 11 loses power, the pump inlet pressure rises sharply due to the water hammer effect. At this time, the check valve 5 opens to prevent the water hammer effect from damaging the circulation pump 11 and the heat exchanger 12, thereby ensuring the service life of the voltage stabilizing component 2.

[0040] In some embodiments, the cooling system 100 further includes a safety valve 6, which is connected to the other end of the circulating pump 11, so that when the pressure of the heat exchange medium flowing out of the circulating pump 11 is higher than a preset value, the safety valve 6 opens so that the heat exchange medium flowing out of the circulating pump 11 flows out through the safety valve 6. Specifically, Figure 1 As shown, the inlet of the safety valve 6 is connected to the outlet of the circulating pump 11. When the outlet pressure of the circulating pump 11 is higher than a preset value, the safety valve 6 opens, so that a part of the heat exchange medium in the circulating pump 11 flows out through the safety valve 6 to reduce the outlet pressure of the circulating pump 11.

[0041] In some embodiments, the cooling system 100 further includes a pressure relief solenoid valve 7, which is connected to the other end of the circulation pump 11, so that when the pressure of the heat exchange medium flowing out of the circulation pump 11 is higher than a preset value, the pressure relief solenoid valve 7 is opened so that the heat exchange medium flowing out of the circulation pump 11 flows out through the pressure relief solenoid valve 7. Specifically, Figure 1 As shown, the outlet of the pressure relief solenoid valve 7 flows out from the outlet of the circulating pump 11. When the outlet pressure of the circulating pump 11 is higher than a preset value, the pressure relief solenoid valve 7 opens, so that a part of the heat exchange medium in the circulating pump 11 flows out through the pressure relief solenoid valve 7 to reduce the outlet pressure of the circulating pump 11.

[0042] In some embodiments, the heat exchanger 12 includes a first channel (not shown in the figure) and a second channel (not shown in the figure) for heat exchange. The two ends of the first channel are respectively connected to the other end of the circulation pump 11 and the external device 8, so that the heat exchange medium flowing out of the circulation pump 11 flows into the external device 8 through the first channel, and the second channel is suitable for passing industrial circulating water, so that the heat exchange medium in the first channel exchanges heat with the industrial circulating water in the second channel. Specifically, the inlet of the first channel is connected to the outlet of the circulation pump 11, the outlet of the first channel is connected to the external device 8, and the second channel can pass industrial circulating water, so that the heat exchange medium exchanges heat with the industrial circulating water in the second channel through the first channel to reduce the temperature of the heat exchange medium in the first channel, and the heat exchange medium in the first channel is passed into the external device 8 to cool the external device 8.

[0043] The cooling system 100 of the embodiment of the utility model, after the auxiliary equipment cooling return water (heat exchange medium flowing out of the external equipment 8) is removed from the impurities by the filter valve group, enters the circulating pump 11 for pressurization, enters the heat exchanger 12, exchanges heat with the external industrial circulating water, and after cooling down, is transported as auxiliary equipment cooling water through the closed circulation water supply main pipe to the auxiliary equipment cooling water user for heat exchange. In order to ensure the stability of the cooling water pressure, a pressure stabilizing component 2 is set at the inlet of the circulating pump 11. This scheme uses a constant pressure tank for water replenishment and pressure regulation. There is an air bag filled with nitrogen in the tank body. Its working principle is that when it starts running, the gas constant pressure tank is filled with water, compressing the gas in the air bag to maintain the system pressure at p1 state. As the water replenishment is carried out, the water level rises to the highest, and the pressure rises to p2. The pressure at the constant pressure point is maintained between p1 and p1 during the operation of the system. When the water level rises again and the pressure continues to rise, the overflow valve 21 is automatically opened to discharge the water, and the overflow valve 21 is automatically closed after the pressure is restored. When the water level in the tank reaches the lowest level due to water loss in the system during operation, water is replenished through the water replenishment regulating valve 3, and the pump is stopped when the water level reaches the highest level. The tank is equipped with a first detection component and a second detection component. At the same time, a two-stage pressure relief device, a water supply safety valve 6 and a water supply pressure relief solenoid valve 7, are set at the outlet of the circulating pump 11 to avoid excessive pressure. A check valve 5 is set in the bypass of the circulating pump 11. Under normal operating conditions, the inlet pressure of the circulating pump 11 is low and is in a closed state. When the circulating pump 11 loses power, the pump inlet pressure rises sharply due to the water hammer effect. At this time, the bypass check valve 5 of the circulating pump 11 is opened to prevent the water hammer effect from damaging the circulating pump 11 and the plate heat exchanger 12.
