Detailed Implementation

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0045] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0046] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0047] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0048] See also Figure 1-5 As shown, according to an embodiment of the present invention, a refrigerant plate assembly is provided, which includes a refrigerant plate 21, and the refrigerant plate 21 is provided with a flow channel for being connected in series in the refrigerant circulation loop.

[0049] The refrigerant plate 21 may be provided with a first transition block 26, and the aforementioned flow channel may include a first flow channel 261 disposed on the first transition block 26. The first flow channel 261 is used to connect the exhaust port of the compressor 1 and the refrigerant inlet 231 of the condenser. A first heat insulation pad 27 is provided between the first transition block 26 and the refrigerant plate 21 to reduce heat exchange between the first flow channel 261 and the refrigerant plate 21.

[0050] And / or, a second transition block 28 may be provided on the refrigerant plate 21, and the aforementioned flow channel may include a second flow channel 281 provided on the second transition block 28. The second flow channel 281 is used to connect the refrigerant outlet 232 of the condenser and the refrigerant inlet 247 of the throttling device. A second heat insulation pad 29 is provided between the second transition block 28 and the refrigerant plate 21 to reduce heat exchange between the second flow channel 281 and the refrigerant plate 21.

[0051] Alternatively, a third adapter block 243 may be provided on the refrigerant plate 21. This third adapter block 243 has a mounting hole 248 for mounting the throttling device 240 and communicating with the refrigerant inlet 247 of the throttling device. The aforementioned flow channel may include a third flow channel 5 provided on the third adapter block 243. One end of the third flow channel 5 extends through the mounting hole 248, allowing it to communicate with the refrigerant inlet 247 of the throttling device. The other end 51 of the third flow channel is used to communicate with the refrigerant outlet 232 of the condenser. A third heat insulation pad 244 is provided between the third adapter block 243 and the refrigerant plate 21 to reduce heat exchange between the third flow channel 5 and the refrigerant plate 21.

[0052] The aforementioned refrigerant plate assembly can be applied to integrated thermal management devices. The refrigerant plate 21 of the assembly is a flow channel integrated device, with a first flow channel 261, a second flow channel 281, and a third flow channel 5. The discharge port of the compressor 1 and the refrigerant inlet 231 of the condenser are connected through the first flow channel 261 on the refrigerant plate 21. The refrigerant outlet 232 of the condenser and the refrigerant inlet 247 of the throttling device are connected sequentially through the second flow channel 281 and the third flow channel 5. The refrigerant plate 21 has a fourth flow channel 3, through which the refrigerant outlet 249 of the throttling device is connected to the refrigerant inlet of the evaporator 22. The refrigerant outlet of the evaporator 22 is connected to the suction port of the compressor 1. By integrating the compressor 1, condenser 23, throttling device 240, and evaporator 22 onto the refrigerant plate 21, this integrated solution significantly reduces the refrigerant charge, lowers system energy consumption and operating costs, and meets environmental protection requirements. Integrated design makes the system more compact, reduces unnecessary energy loss, and improves overall energy efficiency.

[0053] In this system, the first flow channel 261, the second flow channel 281, and the third flow channel 5 all have relatively high temperatures, while the fourth flow channel 3 and the evaporator 22 have relatively low temperatures. When the system is running, the first flow channel 261, the second flow channel 281, and the third flow channel 5 will experience significant heat exchange with the low-temperature fourth flow channel 3 and the evaporator 22 through the refrigerant plate 21, which will reduce the system's cooling efficiency. In the example above, by designing the first flow channel 261 on the first transition block 26 and placing a first heat insulation pad 27 between the first transition block 26 and the refrigerant plate 21, the heat exchange between the first flow channel 261 and the refrigerant plate 21 can be reduced. Similarly, by designing the second flow channel 281 on the second transition block 28 and placing a second heat insulation pad 29 between the second transition block 28 and the refrigerant plate 21, the heat exchange between the second flow channel 281 and the refrigerant plate 21 can be reduced. Similarly, by designing the third flow channel 5 on the third transition block 243 and placing a third heat insulation pad 244 between the third transition block 243 and the refrigerant plate 21, the heat exchange phenomenon between the third flow channel 5 and the refrigerant plate 21 can be reduced. Thus, by adding heat insulation pads to the contact areas with excessive temperature differences, the reduction in cooling efficiency caused by excessive heat transfer can be effectively reduced, thereby improving the overall performance of the system.

[0054] In some implementations, such as Figure 2 and 3 As shown, the refrigerant plate 21 is simultaneously provided with the aforementioned first adapter block 26, second adapter block 28, and third adapter block 243. A first heat insulation pad 27 is provided between the first adapter block 26 and the refrigerant plate 21, a second heat insulation pad 29 is provided between the second adapter block 28 and the refrigerant plate 21, and a third heat insulation pad 244 is provided between the third adapter block 243 and the refrigerant plate 21. The first adapter block 26, the second adapter block 28, and the third adapter block 243 can all be fixed to the refrigerant plate 21 using fasteners such as bolts.

[0055] It should be noted that the aforementioned first heat insulation pad 27, second heat insulation pad 29 and third heat insulation pad 244 must all have low thermal conductivity, high heat insulation performance, excellent high temperature resistance, good resistance to refrigerant corrosion and excellent vibration absorption capacity, such as high-performance materials such as silicone rubber, polyurethane foam, ceramic fiber and phenolic resin.

[0056] In some embodiments, both the aforementioned condenser 23 and evaporator 22 can be plate heat exchangers.

[0057] In some implementations, such as Figure 2As shown, when the refrigerant plate 21 is provided with a first adapter block 26 and the flow channel includes a first flow channel 261 provided on the first adapter block 26, the first flow channel 261 is used to connect the exhaust port of the compressor 1 and the refrigerant inlet 231 of the condenser, and a first heat insulation pad 27 is provided between the first adapter block 26 and the refrigerant plate 21, the first adapter block 26 has a first end face, the first heat insulation pad 27 is located between the first end face and the refrigerant plate 21, and a first heat insulation groove 262 is provided on the area of ​​the first end face opposite to the first heat insulation pad 27.

[0058] In the above example, by opening a first heat insulation groove 262 on the end face of the first adapter block 26 opposite to the first heat insulation pad 27, the direct contact area between different temperature zones can be further reduced, the heat flux between different temperature zones can be further reduced, the cooling efficiency caused by excessive heat transfer can be effectively reduced, thereby improving the overall performance of the system.

[0059] In some embodiments, the aforementioned first heat insulation pad 27 may have a first protrusion embedded in the first heat insulation groove 262 to improve the connection stability between the first heat insulation pad 27 and the first adapter block 26.

[0060] In some embodiments, when the refrigerant plate 21 is provided with a second transition block 28 and the flow channel includes a second flow channel 281 provided on the second transition block 28, the second flow channel 281 is used to connect the refrigerant outlet 232 of the condenser and the refrigerant inlet 247 of the throttling device, and a second heat insulation pad 29 is provided between the second transition block 28 and the refrigerant plate 21, the second transition block 28 has a second end face, the second heat insulation pad 29 is located between the second end face and the refrigerant plate 21, and a second heat insulation groove is provided on the area of ​​the second end face opposite to the second heat insulation pad 29.

[0061] In the above example, by opening a second heat insulation groove on the end face of the second adapter block 28 opposite to the second heat insulation pad 29, the direct contact area between different temperature zones can be further reduced, the heat flux between different temperature zones can be further reduced, the cooling efficiency caused by excessive heat transfer can be effectively reduced, thereby improving the overall performance of the system.

[0062] In some embodiments, the aforementioned second heat insulation pad 29 may have a second protrusion embedded in the second heat insulation groove to improve the connection stability between the second heat insulation pad 29 and the second adapter block 28.

[0063] In some implementations, such as Figure 2-3As shown, when the refrigerant plate 21 is provided with a second adapter block 28, the flow channel includes a second flow channel 281 provided on the second adapter block 28. The second flow channel 281 is used to connect the refrigerant outlet 232 of the condenser and the refrigerant inlet 247 of the throttling device. A second heat insulation pad 29 is provided between the second adapter block 28 and the refrigerant plate 21, and a third adapter block 243 is provided on the refrigerant plate 21. The third adapter block 243 is provided with a mounting hole 248, which is used for the installation of the throttling device 240 and communicates with the refrigerant inlet 247 of the throttling device. The flow channel includes a second flow channel 281 provided on the third adapter block 28. The third flow channel 5 on the connecting block 243 has one end extending to the mounting hole 248, and the other end 51 of the third flow channel is used to connect with the refrigerant outlet 232 of the condenser. When the third heat insulation pad 244 is provided between the third connecting block 243 and the refrigerant plate 21, the other end 51 of the third flow channel is connected to the end of the second flow channel 281 that is away from the condenser 23, so that the other end 51 of the third flow channel is connected to the refrigerant outlet 232 of the condenser through the second flow channel 281, and the second flow channel 281 is connected to the refrigerant inlet 247 of the throttling device through the third flow channel 5.

[0064] In the above example, by connecting the other end 51 of the third flow channel to the end of the second flow channel 281 that is away from the condenser 23, the other end 51 of the third flow channel can be connected to the refrigerant outlet 232 of the condenser, and the second flow channel 281 can be connected to the refrigerant inlet 247 of the throttling device.

[0065] To achieve the function of connecting the refrigerant inlet 247 of the aforementioned throttling device with the mounting hole 248, in some embodiments, when the refrigerant plate 21 is provided with a third adapter block 243, and the third adapter block 243 is provided with a mounting hole 248, the mounting hole 248 is used for mounting the throttling device 240 and communicating with the refrigerant inlet 247 of the throttling device, the flow channel includes a third flow channel 5 provided on the third adapter block 243, one end of the third flow channel 5 extends through the mounting hole 248, and the other end 51 of the third flow channel is used to communicate with the refrigerant outlet 232 of the condenser, and a third heat insulation pad 244 is provided between the third adapter block 243 and the refrigerant plate 21, such as Figure 5 As shown, the throttling device 240 is inserted into the mounting hole 248, and the refrigerant inlet 247 of the throttling device is located in the mounting hole 248, so that the refrigerant inlet 247 of the throttling device is connected to the mounting hole 248.

[0066] In the above example, by placing the refrigerant inlet 247 of the throttling device within the mounting hole 248, the function of connecting the refrigerant inlet 247 of the throttling device with the mounting hole 248 can be achieved.

[0067] In a specific application example, such as Figure 4-5As shown, the aforementioned throttling device 240 can be an electronic expansion valve, which includes a valve body 242 and a coil 241 sleeved on the valve body 242. The refrigerant inlet 247 and the refrigerant outlet 249 of the throttling device are both located on the valve body 242. The coil 241 can be mounted on a connector 250, which is fixed to a third adapter block 243 by fasteners such as a first fixing bolt 245. The third adapter block 243 can be fixed to the refrigerant plate 21 by a second fixing bolt 246.

[0068] In some embodiments, when the throttling device 240 is an electronic expansion valve, the electronic expansion valve, the third heat insulation pad 244, and the third adapter block 243 can form an electronic expansion valve assembly 24. Figure 4 An exploded view of an electronic expansion valve assembly 24 is shown. Figure 4 As shown, the electronic expansion valve assembly 24 consists of a coil 241, a valve body 242, a third adapter block 243, a third heat insulation pad 244, a first fixing bolt 245, and a second fixing bolt 246. Figure 5 A cross-sectional view of an electronic expansion valve assembly 24 is shown, from Figure 5 The flow direction of the refrigerant can be seen from this. Among them, the third heat insulation pad 244 isolates the part before the valve body 242 throttling from the refrigerant plate 21 as much as possible, effectively avoiding unnecessary heat transfer, thereby improving the thermal management efficiency of the system.

[0069] In some embodiments, when a third adapter block 243 is provided on the refrigerant plate 21, and the third adapter block 243 is provided with a mounting hole 248 for mounting the throttling device 240 and communicating with the refrigerant inlet 247 of the throttling device, and the flow channel includes a third flow channel 5 provided on the third adapter block 243, one end of the third flow channel 5 extending through the mounting hole 248, and the other end 51 of the third flow channel communicating with the refrigerant outlet 232 of the condenser, and a third heat insulation pad 244 is provided between the third adapter block 243 and the refrigerant plate 21, such as Figure 2 As shown, the aforementioned flow channel may also include a fourth flow channel 3 disposed on the refrigerant plate 21. One end 31 of the fourth flow channel is used to connect with the refrigerant outlet 249 of the throttling device in the mounting hole 248, and the other end 32 of the fourth flow channel is used to connect with the refrigerant inlet of the evaporator 22.

[0070] In the above example, the fourth flow channel 3 facilitates the connection between the refrigerant outlet 249 of the throttling device and the refrigerant inlet of the evaporator 22, so as to integrate the evaporator 22 onto the refrigerant plate 21.

[0071] It should be noted that the aforementioned first flow channel 261, second flow channel 281, third flow channel 5 and fourth flow channel 3 can all be flow channel holes.

[0072] In some implementations, such as Figure 2 As shown, the aforementioned refrigerant plate 21 may be provided with a gas-liquid separation chamber 4, which has a refrigerant inlet 42 and a gas outlet 41. The gas outlet 41 is used to communicate with the suction port of the compressor 1. The refrigerant inlet 42 is used to communicate with the refrigerant outlet of the evaporator 22, so that the refrigerant outlet of the evaporator 22 and the suction port of the compressor 1 can be connected through the gas-liquid separation chamber 4. The gas-liquid separation chamber 4 has an end cap 251, which can be opened or closed.

[0073] In the above example, the openable design of the end cap 251 facilitates maintenance and repair, improves the system's flexibility and adaptability, and shortens fault diagnosis and repair time.

[0074] To achieve the function of opening and closing the gas-liquid separation chamber 4 using the end cap 251, in some embodiments, the end cap 251 is detachable. For example, the end cap 251 can be detachably connected to the refrigerant plate 21 using fasteners such as bolts. The end cap 251 can be used to open the gas-liquid separation chamber 4 by disassembly, and to close the gas-liquid separation chamber 4 by installation, thus achieving the function of opening and closing the gas-liquid separation chamber 4 using the end cap 251.

[0075] In some implementations, such as Figure 2 As shown, the aforementioned refrigerant plate 21 is provided with an outlet 411 that extends into the gas-liquid separation chamber 4. The end of the outlet 411 facing away from the gas-liquid separation chamber 4 serves as the aforementioned gas outlet 41. Figure 6 As shown, the end cap 251 is provided with a U-shaped vent pipe 252. When the end cap 251 is closed, the gas-liquid separation chamber 4 is located inside the gas-liquid separation chamber 4, and one end opening 2521 of the U-shaped vent pipe is located at the upper part of the gas-liquid separation chamber 4. The other end opening of the U-shaped vent pipe 252 is connected to the end of the vent hole 411 opposite to the gas outlet 41 through the flow channel hole on the end cap 251. In this way, the gaseous refrigerant in the gas-liquid separation chamber 4 can enter the interior of the U-shaped vent pipe 252 from the one end opening 2521 of the U-shaped vent pipe, and then flow into the vent hole 411 from the other end opening of the U-shaped vent pipe 252, and then into the refrigerant inlet of the evaporator 22. The bottom of the U-shaped pipe is provided with an inlet, and a filter screen 253 is provided at the inlet.

[0076] In the above example, the refrigeration oil at the bottom of the gas-liquid separation chamber 4 can be filtered by the filter screen 253 and flow from the inlet into the U-shaped outlet pipe 252, and then into the system, thus avoiding the accumulation of refrigeration oil inside the gas-liquid separation chamber 4.

[0077] Figure 6A schematic diagram of a gas-liquid separator cover assembly 25 is shown. The gas-liquid separator cover assembly 25 consists of an end cap 251, a U-shaped outlet pipe 252, and a filter screen 253. The gas-liquid separator cover assembly 25 is fixedly connected to the open end of the gas-liquid separator chamber on the refrigerant plate 21 by bolts, realizing the gas-liquid separation function of the gas-liquid separation chamber 4. When the gas-liquid separation chamber 4 is clogged with impurities, the end cap 251 can be easily opened for maintenance and cleaning, ensuring the long-term stable operation of the system.

[0078] In some embodiments, the present invention also provides a thermal management integrated device, which may include the refrigerant plate assembly of any of the above.

[0079] like Figure 1 As shown, the thermal management integrated device of this utility model includes a compressor 1 and a refrigerant-side component 2. The refrigerant-side component 2 includes an evaporator 22, a condenser 23, a throttling device 240, and the aforementioned refrigerant plate assembly.

[0080] The refrigerant flow path is as follows: From the discharge port of compressor 1, it enters condenser 23 through the first flow channel 261 on the first transfer block 26 for heat exchange. In condenser 23, the high-temperature, high-pressure refrigerant releases heat and transforms into low-temperature, high-pressure liquid refrigerant. Then, the liquid refrigerant flows sequentially through the refrigerant outlet 232 of the condenser into the second flow channel 281 of the second transfer block 28 and the third flow channel 5 of the third transfer block 243, and then undergoes throttling and pressure reduction through the throttling device 240. The throttling device 240 can be an electronic expansion valve, which precisely controls the refrigerant flow rate to ensure efficient system operation under different operating conditions. The throttled refrigerant enters evaporator 22 for further heat exchange, absorbing heat and transforming into low-temperature, low-pressure gaseous refrigerant. Subsequently, the gaseous refrigerant enters gas-liquid separation chamber 4 for gas-liquid separation, ensuring that only gaseous refrigerant enters the suction port of compressor 1, completing the refrigerant cycle.

[0081] When the refrigerant plate 21 is provided with the aforementioned first adapter block 26, second adapter block 28 and third adapter block 243, the first adapter block 26, the second adapter block 28 and the third adapter block 243 are all separate from the refrigerant plate 21, and each of the three is provided with a heat insulation pad between itself and the refrigerant plate 21. Figures 7a-7d The results of static thermal simulation of the refrigerant side of the thermal management integrated device are presented. The refrigerant side of the thermal management integrated device of this invention is compared with the refrigerant side of an existing non-separate thermal management integrated device. In the existing non-separate thermal management integrated device, the first transition block 26, the second transition block 28, and the third transition block 243 are all integrally formed on the refrigerant plate 21. Figure 7a and Figure 7b It can be seen that the temperature diffusion is better controlled after the adoption of the split heat insulation design in this utility model. From Figure 7c and Figure 7dIt can be seen that after adopting the split heat insulation design, the overall heat flux on the refrigerant side of this utility model is effectively controlled.

[0082] Detailed ANSYS static thermal simulation analysis was conducted on the refrigerant side of the thermal management integrated device of this invention and the refrigerant side of an existing non-separate thermal management integrated device. The average temperature of the refrigerant side of the existing non-separate thermal management integrated device is 17.989℃, and the maximum heat flux is 2.93W / mm². 3 The average heat flux is 1.0491×10^-2W / mm 3 In comparison, the average temperature on the refrigerant side of the thermal management integrated device of this invention is reduced to 15.282℃, and the maximum heat flux is reduced to 0.3153W / mm². 3 The average heat flux decreased to 5.0675×10^-3 W / mm 3 These data indicate that the refrigerant side of the thermal management integrated device of this invention not only significantly reduces the operating temperature of the refrigerant plate 21, but also enhances the cooling efficiency of the entire system.

[0083] Further calculations show that the average temperature on the refrigerant side of the thermal management integrated device of this invention is reduced by approximately 14.5% compared to the refrigerant side of existing non-separate thermal management integrated devices, the maximum heat flux is reduced by approximately 89.2%, and the average heat flux is reduced by approximately 51.7%. These improvements not only contribute to enhancing the safety and reliability of equipment operation but also significantly reduce energy consumption. The optimized refrigerant plate 21 can more effectively manage heat distribution in practical applications, improving the overall cooling efficiency of the system.

[0084] In some embodiments, the present invention also provides a thermal management system, which may include the refrigerant plate assembly of any of the above; or include the thermal management integrated device described above.

[0085] In some embodiments, the present invention also provides a vehicle that may include the refrigerant plate assembly of any of the above; or include the thermal management integrated device described above; or include the thermal management system described above.

[0086] The aforementioned vehicles can be electric vehicles, such as new energy vehicles.

[0087] This utility model provides a split-integrated automotive thermal management refrigerant-side solution, which significantly improves the system's thermal management performance and overall cooling efficiency by optimizing the heat flux in high and low temperature zones, thereby meeting the stringent requirements of new energy vehicles.

[0088] Specifically, this invention effectively reduces the direct contact area between different temperature zones by dividing the high-temperature and low-temperature zones on the refrigerant side, significantly reducing heat flux. This partitioned design not only improves the system's thermal management efficiency but also enhances its stability and reliability. Secondly, the integrated design significantly reduces the refrigerant charge, lowering system energy consumption and operating costs, and meeting environmental protection requirements. The integrated design makes the system more compact, reducing unnecessary energy loss and improving overall energy efficiency. Furthermore, adding heat insulation pads to contact areas with large temperature differences effectively prevents a decrease in refrigeration efficiency due to excessive heat transfer, improving the overall system performance. Finally, the openable end cap 251 of the gas-liquid separation chamber 4 facilitates maintenance and repair, improving the system's flexibility and adaptability, shortening fault diagnosis and repair time, and thus ensuring long-term stable operation of the system.

[0089] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
