The present utility model can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model.

[0037] It should be noted that the diagrams provided in this embodiment only illustrate the basic concept of the present utility model in a schematic manner. Therefore, only the components related to the present utility model are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components during actual implementation. The types, quantities, and proportions of the components during actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0038] Please refer to Figures 1 to 12As shown in the figure, the present utility model proposes an integrated thermal management system and a vehicle to solve the problems in the prior art that the water-cooled condenser, battery cooler, liquid storage dryer, coolant heater, etc. are independently arranged and fixed to the vehicle body through mounting brackets respectively, resulting in a large occupied space and complex pipeline connections between various components. Specifically, the integrated thermal management system includes an integrated module and fixed mounting parts 101. The integrated module is a modular structure formed by integrating structures such as a liquid storage dryer 10, a battery cooler 20, a water-cooled condenser 30, and a coolant heater 40. The fixed mounting parts 101 are distributed around the integrated module. The integrated module is fixedly connected to the vehicle body or bracket through the fixed mounting parts 101, and the integrated module is fixedly connected to the vehicle body through the multi-point arranged fixed mounting parts 101 to improve the installation convenience and reliability.

[0039] Please refer to Figures 1 to 4 As shown in the figure, in this embodiment, the liquid storage dryer 10 includes a body and a refrigerant dryer 11 arranged in the body. The body includes a base 12 and an upper shell 13. The upper shell 13 is fixedly connected to the base 12 and forms a refrigerant flow channel 102. The refrigerant flow channel 102 is, for example, a serpentine flow channel. The refrigerant dryer 11 is arranged in the refrigerant flow channel 102. For example, at least two refrigerant dryers 11 are distributed along the extension direction of the refrigerant flow channel 102. Among them, the extension direction of the refrigerant flow channel 102 refers to the flow direction of the refrigerant in the flow channel. The refrigerant flowing through the refrigerant flow channel 102 passes through two refrigerant dryers 11 in sequence for drying to improve the drying effect.

[0040] Please refer to Figures 1 to 6 As shown in the figure, in this embodiment, the refrigerant dryer 11 and the base 12 are detachable structures. For example, mounting holes 121 are provided on the base 12. The refrigerant dryer 11 extends into the refrigerant flow channel 102 along the mounting holes 121. The refrigerant dryer 11 is threadedly connected to the mounting holes 121 and sealed, so as to facilitate taking out the refrigerant dryer 11 from the base 12 and facilitating its maintenance or replacement.

[0041] Please refer to Figures 1 to 4 As shown in the figure, in this embodiment, the battery cooler 20 is integrally installed on the body of the liquid storage dryer 10, and the water-cooled condenser 30 is also integrally installed on the body of the liquid storage dryer 10. Specifically, the battery cooler 20 and the water-cooled condenser 30 are fixedly connected to the upper shell 13, for example, by welding, so that the liquid storage dryer 10, the battery cooler 20, and the water-cooled condenser 30 are integrated together.

[0042] Please refer to Figures 1 to 4As shown, in this embodiment, an electronic expansion valve 21 is also integrally installed on the body of the liquid storage dryer 10. Specifically, the electronic expansion valve 21 is fixedly installed on the upper housing 13 and is arranged close to the battery cooler 20. The refrigerant flow path in the battery cooler 20 is communicated with the refrigerant flow path 102 in the liquid storage dryer 10 through the electronic expansion valve 21. For example, the liquid storage dryer 10 is provided with a first outlet 103 and a second outlet. The first outlet 103 and the second outlet are formed on the upper housing 13, and the second outlet is communicated with the battery cooler 20 through the electronic expansion valve 21. When the electronic expansion valve 21 is opened, the refrigerant can flow into the electronic expansion valve 21 through the second outlet and then flow into the battery cooler 20. Correspondingly, since the battery cooler 20 is integrally installed on the body of the liquid storage dryer 10, the distance between the battery cooler 20 and the liquid storage dryer 10 is relatively small, which can effectively save space. At the same time, it can reduce the length of the pipeline, reduce the difficulty of pipeline layout, and thus reduce the cost.

[0043] Please refer to Figures 1 to 4 As shown, in this embodiment, a refrigerant outlet is provided at the bottom of the water-cooled condenser 30. The refrigerant outlet of the water-cooled condenser 30 is communicated with the inlet of the refrigerant flow path 102 inside the liquid storage dryer 10, that is, the refrigerant outlet of the water-cooled condenser 30 can be directly communicated with the refrigerant inlet of the liquid storage dryer 10, so that the refrigerant entering the water-cooled condenser 30 exchanges heat with the low-temperature coolant and then directly enters the liquid storage dryer 10. Integrally installing the water-cooled condenser 30 on the body of the liquid storage dryer 10 can effectively save space. At the same time, it can reduce the length of the connecting pipeline between the water-cooled condenser 30 and the liquid storage dryer 10, reduce the difficulty of pipeline layout, and thus reduce the cost.

[0044] Please refer to Figures 1 to 4As shown, in this embodiment, a substrate 41 is fixed on one side of the liquid storage dryer 10. The substrate 41 is arranged close to the water-cooled condenser 30. The coolant heater 40 is fixedly installed on the substrate 41 and is arranged close to the water-cooled condenser 30. Specifically, a mounting seat 411 is provided on the substrate 41. The coolant heater 40 is fixedly connected to the substrate 41 through the mounting seat 411, so that the coolant heater 40 is integrated with the liquid storage dryer 10, the battery cooler 20, and the water-cooled condenser 30 to form a modular structure, and the coolant heater 40 is close to the water-cooled condenser 30. In this embodiment, a connection pipeline 42 is connected between the first coolant outlet 301 of the water-cooled condenser 30 and the second coolant inlet 401 of the coolant heater 40. Since the coolant heater 40 is integrated with the liquid storage dryer 10, the battery cooler 20, and the water-cooled condenser 30 through the substrate 41, and at the same time the coolant heater 40 is arranged close to the water-cooled condenser 30, it can effectively reduce the length of the connection pipeline 42 between the water-cooled condenser 30 and the coolant heater 40, thereby avoiding the problems of complex pipeline layout and large space occupation caused by using long pipelines for connection, and effectively reducing costs.

[0045] Please refer to Figure 1 、 Figure 5 and Figure 6 As shown, in this embodiment, the fixed mounting member 101 is in a plate-like structure. Specifically, a plurality of fixed mounting members 101 can be respectively fixedly connected to the base 12 and the substrate 41. In this embodiment, the substrate 41, the fixed mounting member 101, and the base 12 are fixedly connected by welding or are of an integrally formed structure. When integrally installed, the battery cooler 20 and the water-cooled condenser 30 can be fixedly connected to the upper shell 13 of the liquid storage dryer 10, such as by welding, and then the upper shell 13 is fixedly connected to the base 12 to integrally install the liquid storage dryer 10, the battery cooler 20, and the water-cooled condenser 30. The coolant heater 40 is fixedly installed on the substrate 41, so that the coolant heater 40 is integrally installed with the liquid storage dryer 10, the battery cooler 20, and the water-cooled condenser 30 to form an integrated module, and then fixedly connected to the vehicle body or the vehicle frame through the fixed mounting members 101 distributed around the integrated module, making the overall vehicle layout more space-saving, improving the utilization rate of the engine compartment layout, being more convenient for the overall vehicle assembly, effectively reducing the length of the connection pipelines between each component at the same time, reducing the pipeline layout difficulty, and reducing the overall vehicle development cost.

[0046] Please refer to Figure 1 、 Figures 7 to 9As shown, in this embodiment, when there is no need to cool the battery pack, the refrigerant flow direction is as follows: The refrigerant enters the water-cooled condenser 30 through the refrigerant inlet 31 on the water-cooled condenser 30. After heat exchange with the low-temperature coolant in the heat exchange core part of the water-cooled condenser 30, it flows into the liquid storage dryer 10 through the refrigerant outlet at the bottom of the water-cooled condenser 30, flows through the refrigerant flow channel 102 in the liquid storage dryer 10, and is dried by multiple refrigerant dryers 11 at the same time. At this time, since there is no need to cool the battery pack, the electronic expansion valve 21 is in the closed state. Therefore, the dried refrigerant flows out of the liquid storage dryer 10 through the first outlet 103; when there is a need to cool the battery pack, the refrigerant flow direction is as follows: The refrigerant enters the water-cooled condenser 30 through the refrigerant inlet 31 on the water-cooled condenser 30. After heat exchange with the low-temperature coolant in the heat exchange core part of the water-cooled condenser 30, it flows into the liquid storage dryer 10 through the refrigerant outlet at the bottom of the water-cooled condenser 30, flows through the refrigerant flow channel 102 in the liquid storage dryer 10, and is dried by multiple refrigerant dryers 11 at the same time. At this time, since there is a need to cool the battery pack, the electronic expansion valve 21 is in the open state. Therefore, a part of the refrigerant flows through the second outlet to the electronic expansion valve 21, and after passing through the electronic expansion valve 21, it flows into the battery cooler 20. The refrigerant flowing into the battery cooler 20 exchanges heat with the high-temperature coolant in the heat exchange core body of the battery cooler 20 and then flows out from the refrigerant outlet 22 of the battery cooler 20.

[0047] Please refer to Figure 1 、 Figures 10 to 12 As shown, in this embodiment, the coolant flow mode between the water-cooled condenser 30 and the coolant heater 40 is as follows: The low-temperature coolant enters the water-cooled condenser 30 through the first coolant inlet 302 of the water-cooled condenser 30. After heat exchange with the high-temperature refrigerant in the heat exchange core part, it is discharged from the first coolant outlet 301, passes through the connecting pipe 42 and the second coolant inlet 401 of the coolant heater 40, enters the coolant heater 40 for secondary heating, and then is discharged from the second coolant outlet 402 of the coolant heater 40; the coolant flow mode of the battery cooler is as follows: The coolant enters the battery cooler 20 through the coolant inlet pipe 201 of the battery cooler 20. After heat exchange with the low-temperature refrigerant in the heat exchange core of the battery cooler 20, it is discharged from the coolant outlet pipe 202 of the battery cooler 20.

[0048] Please refer to Figures 1 to 12 As shown, the present utility model also proposes a vehicle, including a vehicle body and an integrated thermal management system. The integrated thermal management system is fixedly connected to the vehicle body through the fixed mounting member 101 thereon. The structure of the integrated thermal management system is the same as or similar to the structure of the integrated thermal management system described in the above embodiment. To avoid repetition, it will not be elaborated here.

[0049] The present utility model provides an integrated thermal management system and a vehicle. By integrating a water-cooled condenser, a battery cooler, a liquid storage dryer, and a coolant heater, and fixedly installing them on the vehicle body through multiple fixed installation parts, the layout of each component is optimized to replace the layout mode in the traditional method where each component is separately arranged and installed. At the same time, by integrating the development of the water-cooled condenser, the battery cooler, the liquid storage dryer, and the coolant heater, it saves more space for the overall vehicle layout, improves the utilization rate of the engine compartment layout, is more convenient for the overall vehicle assembly, saves connecting pipelines at the same time, and reduces the overall vehicle development cost.
