[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0031] The following is for reference. Figure 1 and Figure 2 A thermal management system 100 according to a first aspect embodiment of the present invention is described.
[0032] like Figure 1As shown, the thermal management system 100 according to the first aspect of the present invention includes: a compressor 10, a condenser 20, an ejector 30, a refrigerator module 40, and an air conditioning module 50.
[0033] Specifically, the ejector 30 has a first inlet 31, a second inlet 32, and an ejector outlet 33. The condenser 20 is connected between the compressor 10 and the first inlet 31. The refrigerator module 40 includes a first evaporator 41 and a first throttling element 42. The first throttling element 42 is connected between the ejector outlet 33 and one end of the first evaporator 41. The other end of the first evaporator 41 is connected to the second inlet 32. The air conditioning module 50 includes a second evaporator 51 and a second throttling element 52. The second throttling element 52 and the second evaporator 51 are sequentially connected between the ejector outlet 33 and the compressor 10.
[0034] The refrigerator module 40 is used to cool the vehicle refrigerator, and the air conditioning module 50 is used to cool the vehicle's air conditioning system.
[0035] During the operation of the thermal management system 100, the refrigerant compressed by the compressor 10 enters the condenser 20, where it condenses and dissipates heat. Then, it enters the ejector 30 from the condenser 20 through the first inlet 31. The refrigerant entering through the first inlet 31 is depressurized and accelerated by the ejector 30. At the same time, driven by the refrigerant entering through the first inlet 31, the refrigerant in the refrigerator module 40 enters the ejector 30 through the second inlet 32 and mixes with the refrigerant entering through the first inlet 31. The mixed refrigerant is pressurized and depressurized by the ejector 30 and flows out from the ejector outlet 33.
[0036] A portion of the refrigerant flowing out enters the refrigerator module 40. After its flow rate is regulated by the first throttling element 42, it enters the first evaporator 41 for evaporation. The first evaporator 41 exchanges heat with the storage cavity of the vehicle refrigerator, thus achieving the cooling function of the vehicle refrigerator. The refrigerant flowing out from the first evaporator 41 enters the injector 30 through the second inlet 32 to begin the next working cycle. A portion of the refrigerant flowing out enters the air conditioning module 50. After its flow rate is regulated by the second throttling element 52, it enters the second evaporator 51 for evaporation. The second evaporator 51 exchanges heat with the airflow in the air conditioning duct. The heat-exchanged airflow is blown into the passenger compartment through the air outlet in the passenger compartment, thus achieving the vehicle's air conditioning cooling function. The refrigerant flowing out from the second evaporator 51 enters the compressor 10 to begin the next working cycle. Thus, the cooling operation of the refrigerator module 40 and the air conditioning module 50 can be achieved.
[0037] Understandably, the refrigerator module 40 and the air conditioning module 50 share the compressor 10 and condenser 20, which can reduce the number of parts on the vehicle. During the vehicle design process, fewer relative relationships between the parts need to be considered, which can reduce the design difficulty of the vehicle. In addition, fewer materials are required during the vehicle production process, which can reduce the production cost of the vehicle. Furthermore, it is conducive to the lightweight design of the vehicle and can reduce the maintenance cost during the use of the vehicle.
[0038] By setting up the ejector 30, the ejector 30 can optimize the refrigerant's action process and reduce heat loss during refrigerant transfer.
[0039] According to the first aspect of the present invention, the thermal management system 100 can simplify the thermal management system 100 and reduce the production cost of the vehicle by having the refrigerator module 40 and the air conditioning module 50 share the compressor 10 and condenser 20. By setting the injector 30, the energy loss in the refrigerant transmission process can be reduced, thereby improving the working efficiency of the thermal management system 100.
[0040] In some embodiments of this utility model, such as Figure 1 As shown, the thermal management system 100 also includes a third evaporator 60 and a third throttling element 61, which are connected sequentially between the injection outlet 33 and the compressor 10. The third evaporator 60 is used for heat exchange with the battery.
[0041] During the operation of the thermal management system 100, a portion of the refrigerant flowing out from the injection outlet 33 enters the third evaporator 60 after being adjusted by the second throttling element 52. The refrigerant evaporates and absorbs heat in the third evaporator 60, and then the refrigerant flowing out of the third evaporator 60 enters the compressor 10 to enter the next working cycle. Thus, the third evaporator 60 cools the battery.
[0042] By sharing the compressor 10 and condenser 20 among the battery cooling module, air conditioning module 50, and refrigerator module 40, the component structure of the vehicle can be further simplified, thereby further reducing the design difficulty and production cost of the vehicle.
[0043] In some embodiments of this utility model, such as Figure 1 As shown, the thermal management system 100 further includes: a first branch 70 and a second branch 71, the first branch 70 and the second branch 71 are connected in parallel, and both the first branch 70 and the second branch 71 are connected between the injection outlet 33 and the compressor 10; a second evaporator 51 and a second throttling element 52 are connected in series on the first branch 70; and a third evaporator 60 and a third throttling element 61 are connected in series on the second branch 71.
[0044] Therefore, during the design of the thermal management system 100, when the state of the components on the first branch 70 and the second branch 71 is changed, the mutual interference between the components on the first branch 70 and the second branch 71 is small, which can further reduce the design difficulty of the thermal management system 100.
[0045] In some embodiments of this utility model, such as Figure 1 As shown, the thermal management system 100 also includes: a first three-way valve 80, which has a first interface, a second interface and a third interface. The first interface is connected to the injection outlet 33, the second interface is connected to the first throttling element 42, and the first branch 70 and the second branch 71 are both connected to the third interface.
[0046] During the operation of the thermal management system 100, the refrigerant flowing out of the injection outlet 33 enters the first three-way valve 80 through the first interface. Then, the refrigerant flows to the first throttling element 42 through the second interface, and to the first branch 70 and the second branch 71 through the third interface. Thus, the first three-way valve 80 realizes the connection between the injection outlet 33 and the first throttling element 42, the connection between the injection outlet 33 and the second throttling element 52, and the connection between the injection outlet 33 and the third throttling element 61. The connection structure is relatively simple, which can further reduce the design difficulty of the thermal management system 100.
[0047] In some embodiments of this utility model, such as Figure 1 As shown, the thermal management system 100 also includes: a second three-way valve 81, which has a fourth interface, a fifth interface and a sixth interface. The fourth interface is connected to the third interface, one end of the first branch 70 is connected to the fifth interface, and one end of the second branch 71 is connected to the sixth interface.
[0048] During the operation of the thermal management system 100, the refrigerant flowing out of the third port enters the second three-way valve 81 through the fourth port, then enters the first branch 70 through the fifth port, and enters the second branch 71 through the sixth port. Thus, the third port is connected to the first branch 70 and the second branch 71 through the second three-way valve 81. The connection structure is relatively simple, which can further reduce the design difficulty of the thermal management system 100.
[0049] In some embodiments of this utility model, such as Figure 1 As shown, the thermal management system 100 also includes: a third three-way valve 82, which has a seventh interface, an eighth interface and a ninth interface. The seventh interface is connected to the compressor 10, the other end of the first branch 70 is connected to the eighth interface, and the other end of the second branch 71 is connected to the ninth interface.
[0050] During the operation of the thermal management system 100, the refrigerant in the first branch 70 enters the third three-way valve 82 through the eighth interface, and the refrigerant in the second branch 71 enters the third three-way valve 82 through the ninth interface. Then, the refrigerant in the third three-way valve 82 enters the compressor 10 through the seventh interface. Thus, the first branch 70 and the compressor 10 are connected through a third three-way valve 82, and the second branch 71 and the compressor 10 are connected. The connection structure is relatively simple, which can further reduce the design difficulty of the thermal management system 100.
[0051] In some embodiments of this utility model, the first throttling element 42 is an expansion valve. The expansion valve provides more precise control over the refrigerant state and can dynamically adjust the refrigerant state. By setting the first throttling element 42 as an expansion valve, the working efficiency of the thermal management system 100 can be further improved.
[0052] In some embodiments of this invention, the second throttling element 52 is an expansion valve. An expansion valve provides more precise control over the refrigerant state and allows for dynamic adjustment of the refrigerant state. By setting the second throttling element 52 as an expansion valve, the working efficiency of the thermal management system 100 can be further improved.
[0053] In some embodiments of this invention, the third throttling element 61 is an expansion valve. An expansion valve provides more precise control over the refrigerant state and allows for dynamic adjustment of the refrigerant state. By setting the third throttling element 61 as an expansion valve, the working efficiency of the thermal management system 100 can be further improved.
[0054] In some embodiments of this utility model, such as Figure 2 As shown, the injector 30 includes a suction section 34, a mixing section 35 and a diffuser section 36 connected in sequence, with a first inlet 31 and a second inlet 32 located in the suction section 34, and an injection outlet 33 located in the diffuser section 36.
[0055] During the operation of the thermal management system 100, the refrigerant flowing out of the condenser 20 enters the suction section 34 through the first inlet 31, and the refrigerant flowing out of the first evaporator 41 enters the suction section 34 through the second inlet 32. The two refrigerants are mixed in the mixing section 35, and then diffused through the diffusion section 36 and flow out from the injection outlet 33. Thus, the injector 30 can pressurize the refrigerant during the flow process.
[0056] In some embodiments of this utility model, such as Figure 2 As shown, the injector 30 also includes a nozzle 37, which is disposed in the suction section 34 and connected to the first inlet 31.
[0057] During the operation of the thermal management system 100, the refrigerant flowing out of the condenser 20 enters the nozzle 37 through the first inlet 31. The nozzle 37 depressurizes and accelerates the refrigerant entering through the first inlet 31. The accelerated refrigerant mixes with the refrigerant flowing in through the second inlet 32 in the mixing section 35. This improves the mixing effect of the two refrigerants. The mixed refrigerant is diffused through the diffuser section 36 and then flows out. This improves the consistency of the refrigerant flowing out of the ejector 30, thereby enhancing the refrigerant's effectiveness.
