[0063] The following refers to Figures 1 - 17 Describe an integrated module 100, a thermal management system, and a vehicle according to an embodiment of the present utility model.

[0064] In a first aspect, this application provides an integrated module 100, including: a base body 10, a refrigerant side component 20, and a heat exchanger 30.

[0065] Wherein, referring to Figure 1 、 Figure 2 and Figure 3As shown, the base body 10 has a first side 111 and a second side 121 that are opposite to each other in the first direction. The refrigerant side component 20 is disposed on the first side 111, and the heat exchanger 30 is disposed on the second side 121. The heat exchanger 30 has a refrigerant side inlet / outlet and a cooling medium side inlet / outlet. The refrigerant side inlet / outlet is connected to the base body 10, and the cooling medium side inlet / outlet is used to connect to an external water cooling module.

[0066] It should be noted that the first direction can be defined as the longitudinal or height direction of the integrated module 100, and the second direction can be defined as the horizontal direction of the integrated module 100 (which can be the front-back direction, left-right direction, length direction, width direction, etc.).

[0067] It can be understood that the heat exchanger 30 has a refrigerant side passage communicating with the refrigerant side inlet / outlet and a cooling medium side passage communicating with the cooling medium side inlet / outlet. The refrigerant side passage or the cooling medium side passage can be configured as a capillary tube to achieve the heat exchange between the refrigerant and the cooling medium and improve the heat exchange efficiency. The refrigerant side inlet / outlet is directly connected to the base body 10, and the cooling medium side inlet / outlet is used to be connected to the external water cooling module.

[0068] Specifically, the base body 10 specifically has a first side 111 and a second side 121 in the first direction. The first side 111 is used to mount the refrigerant side component 20, and the heat exchanger 30 can be disposed on the second side 121 so that the heat exchanger 30 and the refrigerant side component 20 can be arranged on both sides of the base body 10 in the first direction.

[0069] According to the integrated module 100 of the embodiment of the present application, by arranging the refrigerant side component 20 and the heat exchanger 30 on the first side 111 and the second side 121 respectively, a stacked arrangement of the heat exchanger 30, the refrigerant side component 20 and the base body 10 in the first direction can be realized, and the space utilization rate in the first direction can be maximized to reduce the space occupation of the integrated module 100 in the second direction perpendicular to the first direction, achieving a miniaturized and compact setting of the integrated module 100 with higher integration degree, which is beneficial to the platform design of the whole vehicle.

[0070] In some embodiments, the refrigerant side inlet / outlet is connected to the second side 121. It can be understood that connecting the refrigerant side inlet / outlet to the second side 121 avoids using pipeline connections, reduces the leakage points, and in addition, reduces the assembly difficulty and further reduces the leakage risk. It should be noted that the refrigerant side inlet / outlet can be inserted into the second side 121, and multiple layers of seals are provided at the insertion position to improve the sealing effect.

[0071] Such as Figure 14 and Figure 15As shown, according to some embodiments of the present application, the integrated module 100 further includes: a cooling medium temperature sensor 40, which is integrated in the heat exchanger 30 and is provided on the physical pipeline at the inlet and outlet of the cooling medium side.

[0072] Specifically, physical pipelines are provided on the cooling medium inlet, cooling medium outlet, refrigerant inlet, and refrigerant outlet of the heat exchanger 30 to facilitate connection with the external water cooling module and the second side 121. The cooling medium temperature sensor 40 is integrated on the physical pipeline at the cooling medium inlet, and can measure the temperature of the cooling medium in real time at the cooling medium inlet. While improving the temperature measurement accuracy, the integrated setting of the cooling medium temperature sensor 40 on the heat exchanger 30 can be realized, reducing the layout difficulty, and further rationally utilizing the space in the first direction to improve the compactness of the integrated module 100.

[0073] It should be noted that at least part of the pipe section of the physical pipeline can be set as a threaded section, and the cooling medium temperature sensor 40 can be provided with a threaded connection part and is fastened to the threaded section through the threaded connection part to realize the integrated setting of the cooling medium temperature sensor 40 on the heat exchanger 30.

[0074] As Figure 15 shown, in some embodiments, the refrigerant side inlet and outlet and the cooling medium inlet and outlet are located on both sides of the heat exchanger 30 in the first direction; as Figure 14 shown, in other embodiments, the refrigerant side inlet and outlet are located on both sides in the first direction, and the cooling medium inlet and outlet are on the same side as the refrigerant side inlet or on the same side as the refrigerant side outlet.

[0075] It can be understood that Figure 15 in the embodiments shown, the integration degree of the integrated module 100 can be further improved, and the space occupation can be reduced, while Figure 14 in the embodiments shown, although the integration degree is slightly lower than that of Figure 15 the embodiments, the pipeline layout difficulty is lower and the assembly efficiency is higher.

[0076] As Figure 1 shown, in some embodiments, the heat exchanger 30 has a heat exchange body 31 and a mounting bracket 32. The mounting bracket 32 is located between the heat exchange body 31 and the base 10 and is configured as a sheet metal part.

[0077] Specifically, a clamping structure, a plugging structure or an installation ear structure can be provided on the heat exchange body 31, and a connection structure matching with the clamping structure, the plugging structure or the installation ear structure is provided on the installation bracket 32 to fix the heat exchange body 31 on the installation bracket 32. The installation bracket 32 is used to fix the heat exchange body 31 on the base body 10, improving the connection stability and reliability between the heat exchanger 30 and the base body 10. At the same time, with the installation bracket 32 located between the heat exchange body 31 and the base body 10, the installation bracket 32 and the heat exchange body 31, and the base body 10 and the installation bracket 32 can be assembled in sequence, reducing the assembly difficulty, improving the assembly efficiency, and further making full use of the space in the first direction.

[0078] It can be understood that the installation bracket 32 can be configured as a sheet metal part, and its height can be adjusted according to the installation dimensions of the integrated module 100, with higher structural strength and improved adaptability of the heat exchanger 30, enabling the heat exchanger 30 to be integrated into integrated modules 100 of different specifications and sizes.

[0079] As Figure 14 shown, further, the heat exchanger 30 further has an installation block 33, and the installation block 33 is arranged on the surface of the heat exchange body 31 facing away from the second side 121.

[0080] Specifically, the installation bracket 32 is connected to the base body 10 on the second side 121, the heat exchange body 31 is fixed on the installation bracket 32, and an installation block 33 is further formed on the surface of the heat exchange body 31 facing away from the second side 121. Then, the installation block 33 can be used as a vehicle installation point, increasing the number of fixed points of the integrated module 100 on the vehicle body. And relative to the base body 10, through the setting of the installation block 33, an additional vehicle installation mating point can be added to the integrated module 100 on the second side 121, which can not only improve the overall fixing stability and reliability of the integrated module 100 on the vehicle, but also improve the vibration of the heat exchanger 30 and enhance the connection stability and reliability between the heat exchanger 30 and the base body 10.

[0081] It should be noted that the installation block 33 can be a columnar block, on which a threaded hole or a projection welding nut is provided for connection with the vehicle body.

[0082] As Figure 4 and Figure 13 shown, according to some embodiments of the present application, the base body 10 includes: a first plate body 11 and a second plate body 12. The first plate body 11 and the second plate body 12 are oppositely arranged in the first direction and jointly form a plurality of refrigerant flow channels a extending in a direction perpendicular to the first direction. The refrigerant side assembly 20 is connected to the refrigerant flow channels a.

[0083] Specifically, in combination with Figure 1 、 Figure 4As shown, the base 10 is constructed as a split plate structure, including a first plate body 11 and a second plate body 12 assembled in a first direction. The first plate body 11 and the second plate body 12 can be assembled by welding, threaded fastening, etc., and a refrigerant flow channel a is assembled between the first plate body 11 and the second plate body 12. The refrigerant flow channel a can be bent and extended on the first plate body 11 and the second plate body 12, and can be constructed as a multi-layer flow channel structure in the first direction, but the whole is perpendicular to the first direction, and mounting holes can be formed on the first side 111 defined by the first plate body 11 and the second side 121 defined by the second plate body 121, and the refrigerant side component 30 is connected to the refrigerant flow channel a through the mounting holes.

[0084] Furthermore, combined with Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10 As shown, the refrigerant flow channel a extends in a direction perpendicular to the first direction and extends to the peripheral edge area of the first plate body 11 and the second plate body 12 (i.e., on the side of the base body 10). A flow channel interface b can be defined in the peripheral edge area, and the flow channel interface b can be used to connect with surrounding components. There are multiple flow channel interfaces b, which are used for the assembly of heat exchange components such as the compressor 1, the in-vehicle condenser 5, the out-of-vehicle condenser 4, and the in-vehicle evaporator 6, such as: the compressor refrigerant outlet is connected to one flow channel interface b, and the compressor refrigerant inlet is connected to another flow channel interface b.

[0085] In this way, the flow channel interfaces b of the base 10 are all formed on the side of the base 10, and the other refrigerant side components of the thermal management system can be connected to the flow channel interfaces b located on the side of the base 10 through the refrigerant side connecting pipeline to realize the refrigerant side layout of the thermal management system. On the one hand, the probability of interference between the refrigerant side component 20 and the refrigerant side connecting pipeline can be reduced, the difficulty of assembly can be reduced, and the convenience of disassembly and assembly can be improved. On the other hand, there is no need to set a sealing plug between the refrigerant side connecting pipeline and the flow channel interface b, which can reduce the risk of leakage, so that the integrated module 100 of the embodiment of the present application is better compatible with the new refrigerant, and can meet the high requirements of the new refrigerant for high pressure resistance and leakage resistance.

[0086] like Figure 2 , Figures 4 - 11 As shown, further, the refrigerant side component 20 includes an electronic expansion valve and a solenoid valve, wherein the electronic expansion valve may be multiple, the solenoid valve may be multiple, the first plate body 11 is located on a side surface in the first direction to define a first side 111, and the first side 111 is provided with a mounting hole c connected to the refrigerant flow channel a, the electronic expansion valve and the solenoid valve are both installed in the mounting hole c, and the second plate body 12 is defined on a side away from the first plate body 11 in the first direction. The second side 121 is used to fix the heat exchanger 30.

[0087] It is understandable that according to the requirements of the thermal management system, the refrigerant valve assembly 20 further includes one-way valves, and there can be multiple one-way valves, which are also installed in the mounting holes c.

[0088] Specifically, there can be multiple mounting holes c, and the multiple mounting holes c can be respectively used for installing an electronic expansion valve, an electronic valve, and a one-way valve. The mounting holes c communicate with the refrigerant flow channel a, so that the electronic expansion valve and the solenoid valve arranged in the mounting holes c can control the opening degree, on-off state, and flow rate of the refrigerant flow channel a, etc., to reduce the control difficulty of the integrated module 100 and the thermal management system, and improve the reliability and stability of the integrated module 100.

[0089] See Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown in

[0090] and

[0091] See Figures 4 - 8 As shown, the circular, semi-circular, and cam-shaped contours located outside the mounting holes c, that is, the profiling structure outside the mounting holes c, the projection profile of the mounting holes c can be designed by profiling based on the outer shape profile of the valve body arranged in the mounting holes c. On the premise of ensuring the structural strength of the base body 10, the weight of the first plate body 11 can be reduced to meet the requirements of vehicle lightweight design.

[0092] For example Figure 16 As shown, further, the electronic expansion valve is installed in the mounting hole c through the mounting buckle 80, and / or the solenoid valve is installed in the mounting hole c through the external thread formed on the valve body.

[0093] Specifically, the coil of the small-diameter electronic expansion valve passes through Figure 16The shown installation buckle 80 is fixed in the installation hole c. Both the large-aperture electronic expansion valve and the solenoid valve can be fixed on the installation hole c through internal threads, which can reduce the layout difficulty of the refrigerant-side component 20 on the base body 10 and improve the assembly efficiency.

[0094] It should be noted that the electronic expansion valve can be installed in the installation hole c through the installation buckle 80, and the electronic expansion valve can also be installed in the installation hole c through the external thread formed on the valve body. Of course, the electronic expansion valve can also be fixed to the installation hole c through the installation buckle 80 while having an external thread formed on itself, so as to improve the fixing stability and reliability of the electronic expansion valve on the first plate body 11.

[0095] As Figure 12 and Figure 13 As shown, in some embodiments, a first positioning portion 112 is provided on one side of the first plate body 11 facing the second plate body 12, and a second positioning portion 122 cooperating with the first positioning portion 112 is provided on one side of the second plate body 12 facing the first plate body 11, so as to achieve anti-fooling during the assembly of the first plate body 11 and the second plate body 12.

[0096] Specifically, multiple, such as two, three or more first positioning portions 112 can be provided on the first plate body 11, and multiple second positioning portions 122 can be provided on the second plate body 12 at corresponding positions. The first positioning portion 112 and the second positioning portion 122 can be configured as a concave-convex mating structure, that is, the first positioning portion 112 is configured as a convex column, and the second positioning portion 122 is configured as a groove for plugging and mating with the protrusion, or the first positioning portion 112 is configured as a groove, and the second positioning portion 122 is configured as a convex column for plugging and mating with the first positioning portion 112, so as to realize the positioning before the assembly of the first plate body 11 and the second plate body 12.

[0097] Exemplarily, the first plate body 11 and the second plate body 12 are welded and assembled by a welding process. The first positioning portion 112 on the first plate body 11 and the second positioning portion 122 on the second plate body 12 are positioned and mated, so as to reduce the installation misalignment problem between the first plate body 11 and the second plate body 12 during the welding process, improve the sealing performance of the base body 10 after welding, so that it can meet the high-pressure and high-sealing requirements of the new refrigerant, and the positioning is realized through the first positioning portion 112 and the second positioning portion 122, which can simplify the tooling fixture. There is no need to set a positioning structure on the tooling fixture, which can reduce the production line cost, and the refrigerant flow channel a obtained by the welding process (such as brazing) has good sealing performance and bursting resistance.

[0098] As Figure 13 As shown, a hollow hole d is provided on the first plate body 11 and / or the second plate body 12, and the hollow hole d is located between adjacent refrigerant flow channels a.

[0099] Specifically, in some embodiments, a hollowed-out hole d is provided on the first plate body 11. In some other embodiments, a hollowed-out hole d is provided on the second plate body 12. In a preferred embodiment, hollowed-out holes d are provided on both the first plate body 11 and the second plate body 12.

[0100] Among them, the hollowed-out hole d can be obtained by water cutting on the first plate body 11 or the second plate body 12. The hollowed-out hole d can be located between adjacent refrigerant flow channels a, which can not only reduce the weight of the base body 10 to meet the lightweight requirement, but also improve the cross-heat transfer between adjacent refrigerant flow channels a through the hollowed-out hole d, reduce the influence of envy heat transfer, and improve the heat transfer efficiency.

[0101] Such as Figure 1 shown, according to some embodiments of the present application, the refrigerant side assembly 20 further includes: a first sensor 50 and a wire harness module 60. The first sensor 50 is disposed on the first side 111 and is used to measure the outlet refrigerant pressure of the vehicle exterior condenser. The wire harness module 60 is integrated on the first side 111, and the plug connector and the wire harness of the wire harness module 60 both have anti-misalignment limit structures, so that by setting the anti-misalignment limit structures of the plug connector and the wire harness, the probability of incorrect insertion of the wire harness and the plug connector can be reduced.

[0102] In some embodiments, it further includes: an adapter 70, and the refrigerant inlet and outlet are connected to the second side 121 through the adapter 70.

The low-temperature and low-pressure gas enters the gas-liquid separator 2 and the compressor 1 through the external pipeline for air conditioning refrigeration cycle operation.

[0116] 2. Air conditioning heating mode

[0117] In the vehicle heating mode, as Figure 17 the compressor 1 discharges high-temperature and high-pressure gaseous refrigerant. The refrigerant flowing out of the compressor 1 is connected to the internal condenser 5 through a pipeline.

Subsequently, it enters the integrated module 10 through the pipeline connection interface 202, passes through the check valve 32a, and then through the internal flow channels 301 and 303, and the check valve 31a enters the flow channel 302. Subsequently, the refrigerant flows through the electronic expansion valve 11a for throttling expansion, and is connected to the battery cold plate 3 through the pipeline. At this time, the low-temperature and low-pressure gas-liquid mixture absorbs the battery heat and evaporates, realizing the temperature reduction when the power battery temperature is too high. The refrigerant enters the integrated module 10 again through the pipeline connection interface 207, and enters the electronic expansion valve 14a respectively after flowing through the flow channel 305.
