[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] Reference below Figure 1 A heat exchange medium module 100 according to an embodiment of the present invention is described.

[0028] like Figure 1 As shown, the heat exchange medium module 100 according to the embodiment of the utility model includes: a first driving member 50 , a heat exchanger 40 , an overflow tank 70 , a medium storage tank 80 , a second driving member 60 and a first multi-way valve 10 .

[0029] The first driving member 50 and the heat exchanger 40 are used to form a first circulation loop 1 with the heat exchange member 90; the overflow tank 70 is connected to the heat exchanger 40; the first multi-way valve 10 has a first interface 11, a second interface 12 and a third interface 13, and the first interface 11 is connected to the first circulation loop 1; the medium storage tank 80, the second driving member 60, the second interface 12, and the first interface 11 form an injection flow path 3, and the first interface 11, the third interface 13, and the medium storage tank 80 form a return flow path 4.

[0030] The first driving member 50 and the heat exchanger 40 are used to form a first circulation loop 1 with the heat exchange member 90, that is, the first driving member 50, the heat exchanger 40 and the heat exchange member 90 are connected in sequence, specifically, the first driving member 50 is connected with the heat exchange member 90 through a pipeline, the heat exchange member 90 is connected with the heat exchanger 40 through a pipeline, and the heat exchanger 40 is connected with the first driving member 50 through a pipeline. The first driving member 50 can drive the heat exchange medium in the first circulation loop 1 to flow.

[0031] As some embodiments of the present application, the first driving member 50 may be a medium pump. As some embodiments of the present application, the heat exchange medium may be a coolant.

[0032] The heat exchanger 40 can perform heat exchange on the heat exchange medium flowing through it. As some embodiments of the present application, the heat exchanger 40 can reduce the temperature of the heat exchange medium flowing through it. The heat exchange component 90 can be, but is not limited to, a fuel cell, a power battery, and the like.

[0033] The overflow tank 70 is connected to the heat exchanger 40. As some embodiments of the present application, the heat exchanger 40 has a second outlet 43. When the heat exchange medium is added to the heat exchange part 90, the gas in the pipeline of the first circulation loop 1 can be discharged into the overflow tank 70 through the second outlet 43 of the heat exchanger 40, and discharged to the external environment by the overflow tank 70. As the heat exchange medium is continuously added to the first circulation loop 1, when the heat exchange medium flows from the second outlet 43 of the heat exchanger 40 to the overflow tank 70, it means that the heat exchange medium is full. As some embodiments of the present application, the second outlet 43 of the heat exchanger 40 is set at the highest point of the first circulation loop 1. Such a setting can make the exhaust of the first circulation loop 1 smooth, and is conducive to improving the reliability of liquid injection, so that the first circulation loop 1 can be filled with heat exchange medium as much as possible.

[0034] The first multi-way valve 10 has a first interface 11, a second interface 12 and a third interface 13, wherein the first interface 11 is connected to the first circulation loop 1 through a pipeline, the second interface 12 is connected to the second driving member 60 through a pipeline, and the third interface 13 is connected to the medium storage tank 80 through a pipeline. As some embodiments of the present application, the first multi-way valve 10 can be an electromagnetic multi-way valve.

[0035] The medium storage tank 80, the second driving member 60, the second interface 12, and the first interface 11 form an injection flow path 3, and the heat exchange medium can be injected into the first circulation loop 1 through the injection flow path 3. As some embodiments of the present application, the heat exchange medium can be injected into the first circulation loop 1 from the medium storage tank 80, the second driving member 60, the second interface 12, and the first interface 11 in sequence. The second driving member 60 can drive the heat exchange medium in the injection flow path 3 to flow to the first multi-way valve 10, and enter the first circulation loop 1 from the first multi-way valve 10 to complete the injection of the first circulation loop 1. As some embodiments of the present application, the second driving member 60 can be a medium pump. The medium storage tank 80 is used to provide heat exchange medium.

[0036] The first interface 11, the third interface 13, and the medium storage tank 80 form a return liquid flow path 4, and the heat exchange medium in the first circulation loop 1 can flow from the first circulation loop 1 into the return liquid flow path 4. As some embodiments of the present application, the heat exchange medium in the first circulation loop 1 can flow from the first interface 11 and the third interface 13 of the first multi-way valve 10 to the medium storage tank 80 in sequence to complete the recovery of the heat exchange medium.

[0037] As some embodiments of the present application, the injection path 3 can be connected to the first circulation loop 1 by controlling the first multi-way valve 10 so that the second interface 12 and the first interface 11 are connected and the third interface 13 is closed.

[0038] As some embodiments of the present application, by controlling the first multi-way valve 10 so that the third interface 13 is connected to the first interface 11 and the second interface 12 is closed, the return liquid flow path 4 can be connected to the first circulation loop 1.

[0039] It should be noted that when it is necessary to inject liquid into the first circulation loop 1, the first multi-way valve 10 can be controlled to connect the second interface 12 and the first interface 11 of the first multi-way valve 10, and the third interface 13 can be closed to connect the injection path 3 with the first circulation loop 1. Driven by the second driving member 60, the heat exchange medium flows from the injection path 3 to the first circulation loop 1. As the heat exchange medium is continuously injected into the first circulation loop 1, the gas in the pipeline of the first circulation loop 1 is discharged from the heat exchanger 40 to the overflow tank 70, and then discharged from the overflow tank 70 to the external environment. When the heat exchange medium flows into the overflow tank 70 from the heat exchanger 40, it means that the first circulation loop 1 is full.

[0040] During the heat exchange process, the heat exchanger 40 in the first circulation loop 1 can perform heat exchange on the heat exchange medium flowing through it to reduce the temperature of the heat exchange medium so that the heat exchange medium can cool down the heat exchange element 90 .

[0041] By controlling the first multi-way valve 10, the third interface 13 of the first multi-way valve 10 is connected to the first interface 11, and the second interface 12 is closed, the return liquid flow path 4 can be connected to the first circulation loop 1, and the heat exchange medium in the first circulation loop 1 can flow back into the medium storage tank 80 through the third interface 13 and the first interface 11 to complete the recovery of the heat exchange medium. As some embodiments of the present application, the setting height of the medium storage tank 80 is lower than the first circulation loop 1, so as to utilize the gravitational potential energy to recover the heat exchange medium. As some embodiments of the present application, the medium storage tank 80 is provided with an exhaust port to maintain the pressure balance inside and outside the medium storage tank 80.

[0042] It can be understood that by injecting liquid into the first circulation loop 1 through the injection flow path 3, the injection rate is high, the injection time is short, and the gas in the first circulation loop 1 can be discharged as much as possible, thereby reducing the probability of the first driving member 50 idling. The heat exchange medium can be recovered through the return liquid flow path 4, and the heat exchange medium in the first circulation loop 1 can be easily and quickly recovered, so that the heat exchange medium can be recycled, which is beneficial to reducing costs.

[0043] Therefore, by providing the heat exchange medium module 100 with an injection flow path 3 and a return flow path 4, liquid can be injected into the first circulation loop 1 through the injection flow path 3, thereby shortening the injection time, and facilitating the discharge of gas in the first circulation loop 1, which can reduce the probability of idling of the first driving component 50 and is beneficial to extending the life of the first driving component 50. In addition, the heat exchange medium can be recovered through the return flow path 4, which can reduce the difficulty of recovering the heat exchange medium.

[0044] As some embodiments of the present application, the heat exchange medium module 100 proposed in the present application can be applied to a laboratory, or the heat exchange medium module 100 proposed in the present application can be applied to a vehicle.

[0045] In some embodiments of the present invention, Figure 1 As shown, the heat exchange medium module 100 also includes: a second multi-way valve 20, the second multi-way valve 20 has a fourth interface 21, a fifth interface 22 and a sixth interface 23, the fourth interface 21 is connected to the overflow tank 70, the fifth interface 22 is connected to the medium storage tank 80, and the sixth interface 23 is connected to the third interface 13; the overflow tank 70, the fourth interface 21, the fifth interface, the medium storage tank 80, the second drive member 60, the second interface 12, and the first interface 11 form an injection flow path 3.

[0046] The heat exchange medium module 100 further includes a second multi-way valve 20, which has a fourth interface 21, a fifth interface 22 and a sixth interface 23. Specifically, the fourth interface 21 is connected to the overflow tank 70 through a pipeline, the fifth interface 22 is connected to the medium storage tank 80 through a pipeline, and the sixth interface 23 is connected to the third interface 13 through a pipeline. The overflow tank 70, the fourth interface 21, the fifth interface, the medium storage tank 80, the second driving member 60, the second interface 12, and the first interface 11 form an injection flow path 3. The second driving member 60 can drive the heat exchange medium in the injection flow path 3 to flow to the first multi-way valve 10, and enter the first circulation loop 1 from the first multi-way valve 10 to complete the injection of the first circulation loop 1.

[0047] As some embodiments of the present application, by controlling the first multi-way valve 10 and the second multi-way valve 20, the second interface 12 of the first multi-way valve 10 is connected to the first interface 11, the third interface 13 is closed, and the fourth interface 21 of the second multi-way valve 20 is connected to the fifth interface 22, and the sixth interface 23 is closed, the injection flow path 3 can be connected to the first circulation loop 1. In this way, not only can the first circulation loop 1 be injected, but also the bubbles in the pipeline between the first multi-way valve 10 and the overflow tank 70 can be discharged.

[0048] As some embodiments of the present application, by controlling the first multi-way valve 10 and the second multi-way valve 20, the third interface 13 of the first multi-way valve 10 is connected to the first interface 11, the second interface 12 is closed, and the fourth interface 21 of the second multi-way valve 20 is connected to the sixth interface 23, and the fifth interface 22 is closed, the heat exchange medium can circulate in the first circulation loop 1. Under this working condition, when the bubbles in the first circulation loop 1 are discharged through the heat exchanger 40, the overflow tank 70 can replenish the first circulation loop 1.

[0049] As some embodiments of the present application, by controlling the first multi-way valve 10 and the second multi-way valve 20, the third interface 13 of the first multi-way valve 10 is connected to the first interface 11, and the second interface 12 is closed, and the fifth interface 22 and the sixth interface 23 of the second multi-way valve 20 are connected, and the fourth interface 21 is closed, the return liquid flow path 4 can be connected to the first circulation loop 1.

[0050] By making the heat exchange medium module 100 include a second multi-way valve 20, and making the overflow tank 70, the fourth interface 21, the fifth interface 22, the medium storage tank 80, the second driving member 60, the second interface 12, and the first interface 11 form an injection flow path 3, the heat exchange medium in the medium storage tank 80 can be directly injected into the first circulation loop 1 under the drive of the second driving member 60, so that the gas in the first circulation loop 1 can be easily discharged, the filling time can be reduced, and it is beneficial to extend the life of the first driving member 50. In addition, the bubbles in the pipeline between the first multi-way valve 10 and the overflow tank 70 can be discharged.

[0051] In some embodiments of the present invention, the second driving member 60 and the medium storage tank 80 are both arranged at a height lower than the first circulation loop 1 .

[0052] Among them, the setting heights of the second driving member 60 and the medium storage tank 80 are both lower than the first circulation loop 1, that is, along the height direction perpendicular to the horizontal plane, the setting height of the second driving member 60 is lower than the first circulation loop 1, and the setting height of the medium storage tank 80 is lower than the first circulation loop 1. As some embodiments of the present application, the second driving member 60 is set at the lowest point of the heat exchange medium module 100, and the medium storage tank 80 is slightly higher than the second driving member 60 and lower than the first circulation loop 1.

[0053] By making the second driving member 60 and the medium storage tank 80 be set at a height lower than the first circulation loop 1, the second driving member 60 and the medium storage tank 80 can be set at a reasonable height, which is beneficial for driving the heat exchange medium in the injection path 3 to flow into the first circulation loop 1 through the second driving member 60, reducing the filling time, and can use gravitational potential energy to recover the heat exchange medium, thereby facilitating the recovery of the heat exchange medium.

[0054] In some embodiments of the present invention, the second driving member 60 is disposed at a height lower than the medium storage tank 80 .

[0055] Among them, along the height direction perpendicular to the horizontal plane, the setting height of the second driving member 60 is lower than the first circulation loop 1, the setting height of the medium storage tank 80 is lower than the first circulation loop 1, and the setting height of the medium storage tank 80 is higher than the second driving member 60.

[0056] By making the second driving member 60 be set at a height lower than the medium storage tank 80, the second driving member 60 can be set at a reasonable height, making it easier for the second driving member 60 to pump the heat exchange medium in the medium storage tank 80 into the first circulation loop 1, thereby reducing the probability of the second driving member 60 idling and increasing the service life of the second driving member 60.

[0057] In some embodiments of the present invention, Figure 1 As shown, the heat exchange medium module 100 further includes: a deionizer 91 , and the deionizer 91 and the first driving member 50 form a deionization loop 5 .

[0058] The heat exchange medium module 100 further includes a deionizer 91 , which forms a deionization loop 5 with the first driving member 50 . Specifically, the deionizer 91 is connected to the first driving member 50 via a pipeline, and the deionizer 91 is arranged in parallel with the first circulation loop 1 .

[0059] By making the heat exchange medium module 100 also include a deionizer 91 and making the deionizer 91 and the first driving member 50 form a deionization loop 5, the ion content of the heat exchange medium in the first circulation loop 1 can be reduced, which is beneficial to improving the safety of the heat exchange medium module 100.

[0060] In some embodiments of the present invention, Figure 1 As shown, the heat exchange medium module 100 further includes: a heater 92 , and the heater 92 is arranged in the deionization circuit 5 .

[0061] The heat exchange medium module 100 further includes a heater 92, which is disposed in the deionization circuit 5. Specifically, the heater 92 is connected to the deionizer 91 through a pipeline. The heater 92 can be used to heat the heat exchange medium flowing through it to increase the temperature of the heat exchange medium. As some embodiments of the present application, the heater 92 can be configured as an electric heater, and whether the heater 92 works can be selectively controlled according to specific working conditions. As some embodiments of the present application, the heater 92 can be controlled to work during cold start.

[0062] By making the heat exchange medium module 100 further include a heater 92 , the temperature of the heat exchange medium can be increased, so as to quickly increase the temperature of the component to be heat exchanged 90 during cold start.

[0063] In some embodiments of the present invention, Figure 1 As shown, the heat exchange medium module 100 also includes: a thermostat 30, the thermostat 30 has a seventh interface 31, an eighth interface 32, and a ninth interface 33, the first driving member 50, the heat exchanger 40, the seventh interface 31, and the eighth interface 32 are used to form a first circulation loop 1 with the heat exchange member 90, and the seventh interface 31, the ninth interface 33, and the first driving member 50 are used to form a second circulation loop 2 with the heat exchange member 90.

[0064] Among them, the heat exchange medium module 100 also includes a thermostat 30, the thermostat 30 has a seventh interface 31, an eighth interface 32, and a ninth interface 33. The seventh interface 31 of the thermostat 30 is connected to the heat exchange component 90 through a pipeline, the eighth interface 32 of the thermostat 30 is connected to the heat exchanger 40 through a pipeline, and the ninth interface 33 of the thermostat 30 is connected to the first driving component 50 through a pipeline.

[0065] The first driving member 50, the heat exchanger 40, the seventh interface 31, and the eighth interface 32 can form a first circulation loop 1 with the heat-exchanged member 90, that is, the heat exchange medium can flow and circulate along the first driving member 50, the heat-exchanged member 90, the seventh interface 31, the eighth interface 32, and the heat exchanger 40 in sequence under the drive of the first driving member 50.

[0066] In addition, the seventh interface 31, the ninth interface 33, and the first driving member 50 are used to form a second circulation loop 2 with the heat exchange member 90, that is, the heat exchange medium can also flow and circulate along the first driving member 50, the heat exchange member 90, the seventh interface 31, and the ninth interface 33 in sequence under the drive of the first driving member 50.

[0067] It should be noted that, during a cold start, the eighth interface 32 of the thermostat 30 can be controlled to be closed, and the seventh interface 31 and the ninth interface 33 can be opened, so that the second circulation loop 2 is a passage, and the heat exchange medium flows in the second circulation loop 2. That is to say, the heat exchanger 40 can be bypassed at this time to quickly increase the temperature of the heat exchange part 90 during a cold start. As the temperature of the heat exchange part 90 gradually increases, the eighth interface 32 can be gradually opened and the ninth interface 33 can be gradually closed, so that the second circulation loop 2 and the first circulation loop 1 are both passages. When the temperature of the heat exchange part 90 is higher than the set temperature value, the eighth interface 32 can be fully opened and the ninth interface 33 can be closed, so that the first circulation loop 1 is a passage.

[0068] This arrangement can adjust the working state of the thermostat 30 according to the actual working conditions, so that the flow path of the heat exchange medium is reasonable, so as to quickly increase the temperature of the heat exchange component 90 during cold start, and reduce the temperature of the heat exchange medium through the heat exchanger 40 when the temperature of the heat exchange medium is high, which is beneficial to improving the structural rationality and reliability of the heat exchange medium module 100.

[0069] In some embodiments of the present invention, Figure 1 As shown, the heat exchange medium module 100 further includes: an air supply member 93 , which is disposed corresponding to the heat exchanger 40 and is used to supply air to the heat exchanger 40 .

[0070] The heat exchange medium module 100 further includes an air supply member 93 , which is disposed corresponding to the heat exchanger 40 , and the air supply member 93 can supply air to the heat exchanger 40 to increase the air flow rate around the heat exchanger 40 .

[0071] By making the heat exchange medium module 100 also include an air supply part 93, the air flow rate around the heat exchanger 40 can be increased to quickly reduce the temperature of the heat exchange medium flowing through the heat exchanger 40, so as to ensure that the heat exchange medium with a suitable temperature enters the heat exchange part 90, which is beneficial to improving the heat exchange efficiency of the heat exchange medium module 100.

[0072] In some examples of the present invention, Figure 1 As shown, the heat exchanger 40 has a first inlet 41 , a first outlet 42 and a second outlet 43 . The first inlet 41 , the first outlet 42 and the first driving member 50 are used to form a first circulation loop 1 with the heat exchange member 90 . The second outlet 43 is connected to the overflow tank 70 .

[0073] Among them, the heat exchanger 40 has a first inlet 41, a first outlet 42 and a second outlet 43. The first inlet 41 is connected to the eighth interface 32 of the thermostat 30 through a pipeline, the first outlet 42 is connected to the first driving member 50 through a pipeline, and the second outlet 43 is connected to the overflow tank 70 through a pipeline. The first inlet 41, the first outlet 42, and the first driving member 50 can form a first circulation loop 1 with the heat exchange member 90.

[0074] When the heat exchange medium flows in the first circulation loop 1, it can enter the heat exchanger 40 through the first inlet 41, and can flow out of the heat exchanger 40 through the first outlet 42. Moreover, the gas (bubbles) in the first circulation loop 1 can be discharged into the overflow tank 70 through the second outlet 43 of the heat exchanger 40, and then discharged to the external environment by the overflow tank 70. In other words, the second outlet 43 can be understood as the exhaust port of the heat exchanger 40.

[0075] Such an arrangement can make the structure of the heat exchanger 40 reasonable, and can participate in the circulation of the heat exchange medium in the first circulation loop 1 through the first inlet 41 and the first outlet 42, and can discharge the gas (bubbles) in the first circulation loop 1 through the second outlet 43, which can reduce the probability of idling of the first driving component 50 and is beneficial to extending the life of the first driving component 50.

[0076] In some embodiments of the utility model, the second outlet 43 is set at a height located at the highest point of the first circulation loop 1. Specifically, along the height direction perpendicular to the horizontal plane, the second outlet 43 is set at a height located at the highest point of the first circulation loop 1. This arrangement is conducive to the smooth discharge of the gas (bubbles) in the first circulation loop 1, and when the heat exchange medium flows from the second outlet 43 of the heat exchanger 40 into the overflow tank 70, it can be judged that the heat exchange medium is full, which is conducive to improving the reliability of liquid injection.
