Technical Field

[0001] This invention relates to the field of automotive thermal management system technology, and more particularly to an automotive thermal management system and an automobile. Background Technology

[0002] Currently, with the continuous development of new energy vehicles, automotive thermal management systems are becoming increasingly important. These systems play a crucial role in automobiles, meeting the thermal management needs of components such as the motor, battery, and passenger compartment.

[0003] In existing technologies, automotive thermal management systems are relatively bulky and have low integration, resulting in numerous gaps within the system. This increases the installation space required and raises costs. Furthermore, the long piping systems for the components in existing automotive thermal management systems undoubtedly increase heat loss, reduce heat exchange efficiency, and further increase costs.

[0004] Therefore, there is an urgent need to design an automotive thermal management system and an automotive vehicle to solve the above technical problems. Summary of the Invention

[0022] To achieve this objective, the present invention adopts the following technical solution:

[0023] The present invention provides an automobile, the automobile including the automobile thermal management system described above.

[0024] The beneficial effects of the automotive thermal management system and the automotive provided by this invention include at least the following:

[0025] This invention provides an automotive thermal management system, which includes a compressor, a condenser, a waste heat recovery unit, a gas injection enthalpy enhancer, a base plate, and a flow channel plate. The condenser, waste heat recovery unit, and gas injection enthalpy enhancer are all mounted on the compressor housing, with the gas injection enthalpy enhancer located between the condenser and the waste heat recovery unit.

The outlet end of the first electronic expansion valve is connected to the waste heat recovery unit, so that the refrigerant after being throttled by the first electronic expansion valve can enter the waste heat recovery unit. One end of the third flow channel unit is connected to the third through-hole unit, and the other end is connected to the compressor's suction port, so that the refrigerant after passing through the waste heat recovery unit flows back to the compressor. By integrating the condenser, the gas injection enthalpy enhancer, and the waste heat recovery unit onto the compressor housing, the gaps between the various components of the automotive thermal management system are reduced, making the structure of the automotive thermal management system simpler and more compact, reducing its size, and increasing its integration. At the same time, through the arrangement of the first, second, and third flow channel units on the flow channel plate, the refrigerant can be directly introduced into the condenser, the gas injection enthalpy enhancer, and the waste heat recovery unit in sequence, thus eliminating the need for connecting pipes in traditional technologies, reducing the layout of connecting pipes, avoiding heat loss of refrigerant in connecting pipes, improving the thermal efficiency of the automotive thermal management system, and saving costs.

[0046] Example 1

[0047] like Figures 1-7As shown, this embodiment provides an automotive thermal management system, which mainly includes a compressor 1, a condenser 2, a waste heat recovery unit 4, a gas injection enthalpy enhancer 3, a base plate 5, and a flow channel plate 6. The condenser 2, waste heat recovery unit 4, and gas injection enthalpy enhancer 3 are all installed on the housing of the compressor 1, and the gas injection enthalpy enhancer 3 is located between the condenser 2 and the waste heat recovery unit 4. The condenser 2, waste heat recovery unit 4, and gas injection enthalpy enhancer 3 are all installed on the base plate 5, and the base plate 5 is provided with a first through-hole unit 100, a second through-hole unit 200, and a third through-hole unit 300. The first through-hole unit 100 communicates with the condenser 2, the second through-hole unit 200 communicates with the gas injection enthalpy enhancer 3, and the third through-hole unit 300 communicates with the waste heat recovery unit 4.

[0048] In addition, in this embodiment, the flow channel plate 6 is disposed on the base plate 5 and is sealed to the base plate 5. The flow channel plate 6 has a first flow channel unit 400, a second flow channel unit 500, and a third flow channel unit 600. One end of the first flow channel unit 400 is connected to the exhaust port of the compressor 1, and the other end is connected to the first through-hole unit 100. The first through-hole unit 100 is connected to the second through-hole unit 200, so that the refrigerant can enter the gas injection enthalpy enhancer 3 from the condenser 2. One end of the second flow channel unit 500 is connected to the second through-hole unit 200, and the other end is connected to the first electronic expansion valve 7. The outlet end of the first electronic expansion valve 7 is connected to the waste heat recovery unit 4, so that the refrigerant after being throttled by the first electronic expansion valve 7 can enter the waste heat recovery unit 4. One end of the third flow channel unit 600 is connected to the third through-hole unit 300, and the other end is connected to the suction port of the compressor 1, so that the refrigerant after passing through the waste heat recovery unit 4 flows back to the compressor 1.

[0049] Based on the above design, in this embodiment, by integrating the condenser 2, the gas injection enthalpy enhancer 3, and the waste heat recovery unit 4 onto the housing of the compressor 1, the gaps between the various components of the automotive thermal management system are reduced, making the structure of the automotive thermal management system simpler and more compact, reducing its size, and improving its integration. Simultaneously, through the arrangement of the first flow channel unit 400, the second flow channel unit 500, and the third flow channel unit 600 on the flow channel plate 6, the refrigerant can be directly and sequentially introduced into the condenser 2, the gas injection enthalpy enhancer 3, and the waste heat recovery unit 4, thus eliminating the need for connecting pipes in traditional technologies, reducing the layout of connecting pipes, avoiding heat loss of refrigerant in the connecting pipes, improving the thermal efficiency of the automotive thermal management system, and saving costs.

[0050] like Figures 4-5As shown, in this embodiment, the automotive thermal management system further includes a mounting plate 8, which is disposed on the flow channel plate 6, and a valve island 9 and a first electronic expansion valve 7 are mounted on the mounting plate 8. The mounting plate 8 improves the sealing performance of the first flow channel unit 400, the second flow channel unit 500, and the third flow channel unit 600 on the flow channel plate 6, avoiding the risk of refrigerant leakage. Optionally, a sealing ring can be provided between the mounting plate 8 and the flow channel plate 6 in this embodiment to further improve the sealing performance.

[0051] It should be noted that the valve island 9 in this embodiment has multiple channels inside, which are used to run pipes connecting electrical components. The valve island 9 can improve the integration of the automotive thermal management system. Optionally, the valve island 9 can be made of metal or non-metal materials, such as stainless steel, aluminum alloy, or engineering plastics.

[0052] like Figures 4-5 As shown, in this embodiment, the first flow channel unit 400 includes a first flow channel a4001 and a first flow channel b4002. The refrigerant can pass through the first flow channel a4001, the condenser 2, and the first flow channel b4002 in sequence before entering the gas replenishment enthalpy enhancer 3. The second through-hole unit 200 includes a second through-hole a2001 and a second through-hole b2002. The second flow channel unit 500 includes a second flow channel a5001 and a second flow channel b5002. The second through-hole a2001 is connected to the second flow channel a5001, and the second through-hole b2002 is connected to the second flow channel b5002. The refrigerant entering the gas injection enthalpy enhancer 3 is divided into two parts. One part of the refrigerant undergoes heat exchange in the heat exchange area of ​​the gas injection enthalpy enhancer 3. After heat exchange, the refrigerant passes through the second through-hole a2001 and the second flow channel a5001 in sequence and then enters the gas injection port of the compressor 1. The other part of the refrigerant passes through the second through-hole b2002 and the second flow channel b5002 in sequence and then enters the first electronic expansion valve 7 for throttling. The throttled refrigerant enters the waste heat recovery unit 4.

[0053] Specifically, the refrigerant enters the condenser 2 from the discharge port of the compressor 1 through the valve island 9, then through the first flow channel a4001 and the first through-hole unit 100 to exchange heat with the coolant (not shown in the figure). Afterward, the refrigerant flows out along the outlet of the condenser 2 and enters the gas injection enthalpy enhancer 3 through the first flow channel b4002. For example... Figures 5-6 As shown, the refrigerant entering the gas injection enthalpy enhancer 3 is divided into two parts, one part of which is refrigerant ( Figure 5 The refrigerant (flow direction shown by the dashed line) undergoes heat exchange in the heat exchange area of ​​the gas replenishment enthalpy enhancer 3. After heat exchange, the refrigerant passes through the second through-hole a2001 and the second flow channel a5001 in sequence before entering the gas replenishment port of the compressor 1; another part of the refrigerant ( Figure 5The refrigerant (flowing in the direction indicated by the dashed line) passes sequentially through the second through-hole b2002 and the second flow channel b5002 before entering the first electronic expansion valve 7 for throttling. The throttled refrigerant then enters the waste heat recovery unit 4. It should be noted that... Figure 6 The solid lines represent high-pressure refrigerant, the dashed lines represent the medium after throttling, and the dotted lines (intersecting areas) represent the heat exchange area of ​​the refrigerant.

[0054] like Figure 3 and Figure 7 As shown, in this embodiment, the automotive thermal management system further includes a liquid receiver dryer 10, which is integrated onto the condenser 2. One end of the liquid receiver dryer 10 is connected to the condenser 2, and the other end is connected to the first through-hole unit 100. The liquid receiver dryer 10 is used to dry the refrigerant. The liquid receiver dryer 10 serves two purposes: firstly, it can temporarily store a certain amount of refrigerant to meet different operating conditions of the automotive thermal management system, thereby improving its flexibility and applicability; secondly, it can filter and dry the refrigerant to ensure its heat exchange performance and improve heat exchange efficiency.

[0055] Furthermore, the liquid receiver dryer 10 in this embodiment includes a cylindrical body (not shown in the figure) and a filter screen 11, a desiccant 12, a liquid receiver plug 13, and a retaining spring 14 arranged sequentially along the refrigerant flow direction. The filter screen 11 and the desiccant 12 are disposed within the cylindrical body, the liquid receiver plug 13 seals the end of the cylindrical body, and the retaining spring 14 is disposed on the liquid receiver plug 13. The filter screen 11 is used to filter the refrigerant, and the desiccant 12 is disposed in a drying bag to dry the refrigerant and ensure its heat exchange performance.

[0056] For example, the liquid receiver dryer 10 in this embodiment can be configured as an arch or a rectangle, thereby facilitating adaptation to other components of the automotive thermal management system, further improving integration, and making the structure of the automotive thermal management system more compact and miniaturized. Of course, operators can also configure the liquid receiver dryer 10 into other shapes according to actual needs, which will not be elaborated here.

[0057] Optionally, in this embodiment, the liquid receiver dryer 10 can be embedded within the condenser 2, or the liquid receiver dryer 10 can be placed on top of the condenser 2, thereby improving the flexibility and versatility of the liquid receiver dryer 10 installation, increasing the integration of the automotive thermal management system, and making the structure more compact. Of course, operators can also integrate the liquid receiver dryer 10 in other locations on the condenser 2 according to actual needs, which will not be elaborated here.

[0058] The automotive thermal management system in this embodiment also includes a second electronic expansion valve 15, which is integrated on the condenser 2. One end of the second electronic expansion valve 15 is connected to the liquid receiver dryer 10, and the other end is connected to the first through-hole unit 100. The first electronic expansion valve 7 is used to throttle the refrigerant discharged from the liquid receiver dryer 10 before it enters the gas injection enthalpy enhancer 3.

[0059] like Figures 1-3 As shown, the condenser 2 and waste heat recovery unit 4 in this embodiment are designed to be non-square so that the outer walls of the condenser 2 and waste heat recovery unit 4 can fit tightly against the outer shell of the compressor 1, thereby making the structure more compact and improving the integration of the automotive thermal management system.

[0060] Optionally, the condenser 2, the gas injection enthalpy enhancer 3, the waste heat recovery unit 4, and the liquid storage dryer 10 can all be fixed by brazing, which improves their reliability and stability, simplifies installation, and improves work efficiency.

[0061] Specifically, in this embodiment, the condenser 2, the gas injection enthalpy enhancer 3, the waste heat recovery unit 4, and the liquid storage dryer 10 are integrated together by brazing, which improves the integration level, makes the installation simpler, and improves the work efficiency.

[0062] Optionally, the condenser 2, the gas injection enthalpy enhancer 3, and the waste heat recovery unit 4 in this embodiment are all plate heat exchangers, and the plate structure of the condenser 2, the gas injection enthalpy enhancer 3, and the waste heat recovery unit 4 in this embodiment can be set to V-shaped, W-shaped, dotted, or internal finned shapes, etc.

[0063] This embodiment also provides a car that includes the above-mentioned car thermal management system. Because the car thermal management system has a high degree of integration and small size, it saves the installation space of the car thermal management system in the car, thereby enabling the car to lay more batteries, improve the energy density of the batteries, reduce range anxiety, and achieve the purpose of saving costs.

[0064] Example 2

[0065] like Figures 8-9 As shown, this embodiment provides an automotive thermal management system. The difference between this system and Embodiment 1 is that the automotive thermal management system in this embodiment eliminates the need for the air-fuel enthalpy enhancer 3 and the second electronic expansion valve 15. In other words, the flow path into the air-fuel inlet of the compressor 1 is eliminated in this embodiment. Thus, when customers have lower energy efficiency requirements for the automotive thermal management system, this embodiment can further reduce costs and weight while meeting customer needs.

[0066] The remaining structure of the automotive thermal management system in this embodiment is the same as that in Embodiment 1, and will not be described in detail here.

[0067] This embodiment also provides a car that includes the above-mentioned car thermal management system. Because the car thermal management system has a high degree of integration and small size, it saves the installation space of the car thermal management system in the car, thereby enabling the car to lay more batteries, improve the energy density of the batteries, reduce range anxiety, and save costs.

[0068] Example 3

[0069] like Figure 10 As shown, this embodiment provides an automotive thermal management system. The difference between this system and the first embodiment is that the liquid receiver dryer 10 is located outside the condenser 2. This arrangement of the liquid receiver dryer 10 has the following advantages: it does not occupy the heat exchange area of ​​the condenser 2, thereby improving the heat exchange capacity of the condenser 2 without changing its volume; it also simplifies the structure of the condenser 2 in this embodiment, reducing costs.

[0070] The remaining structure of the automotive thermal management system in this embodiment is the same as that in Embodiment 1, and will not be described in detail here.

[0071] This embodiment also provides a car that includes the above-mentioned car thermal management system. Because the car thermal management system has a high degree of integration and small size, it saves the installation space of the car thermal management system in the car, thereby enabling the car to lay more batteries, improve the energy density of the batteries, reduce range anxiety, and save costs.
