DETAILED DESCRIPTION

[0052] The features and exemplary embodiments of various aspects of the present invention will be described below. In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. In this article, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0053] Usually, a thermal management system is installed in vehicles and other transportation vehicles. The thermal management system includes a heat exchanger. Two heat exchange fluids can flow in the heat exchanger. The heat exchange fluids can also be the same medium. The two heat exchange fluids flow in their corresponding flow channels and the two heat exchange fluids can achieve heat exchange. Optionally, the two heat exchange fluids can be cooling water and oil, etc. For example, the structure of the electronic control system in the vehicle can be heat exchanged. However, when the vehicle is just started and / or when the vehicle is running in a cold environment, the fluid temperature is low and the viscosity is high. At this time, the flow resistance of the oil when passing through the heat exchanger will be very large, causing a large pressure loss. When the oil passes through the heat exchanger, the oil and the cooling water achieve heat exchange, which is not conducive to the rapid rise of the fluid temperature to the optimal operating temperature of the electric drive device.

[0054] To improve the above problems, Figure 1 and Fig.26 As shown, an embodiment of the present invention provides a thermal management system 2, which includes a first branch 40, an oil pump 50, an integrated device 1 and an electric drive device 61. The oil pump 50 has a first pump port 51 and a second pump port 52. The first pump port 51 can be the outlet of the oil pump 50, and the second pump port 52 can be the inlet of the oil pump 50. The outlet of the first branch 40 can be connected to the inlet of the oil pump 50, and the outlet of the oil pump 50 can be connected to the inlet channel of the integrated device 1. The outlet channel of the integrated device 1 can be connected to the electric drive device 61. Among them, the first branch 40 can include devices such as an oil tank, and the electric drive device 61 can include an electric drive system such as an engine. The fluid flowing out of the integrated device 1 can cool the engine and other structures in the electric drive device 61.

[0055] In this article, for example, the two openings, the outlet of the first branch 40 and the inlet of the oil pump 50, are connected, which can mean that the mouths where the two openings are located are directly sealed and connected to each other, or the two openings are connected through other connecting blocks or connecting pipes, wherein the mouths where the openings are located include the opening and the wall surface that defines the opening.

[0056] The integrated device 1 in the embodiment of the present invention has a bypass channel 101, and the integrated device 1 includes a heat exchange component 10 and a valve component 30. The heat exchange component 10 has a first heat exchange channel 141 and a second heat exchange channel 142. For example, a first fluid such as a medium oil can flow through the first heat exchange channel 141, and a second fluid such as a refrigerant can flow through the second heat exchange channel 142. The valve component 30 includes a valve core component 31, and at least a portion of the first heat exchange channel 141 can be bypassed by controlling the action of the valve core component 31. Through the above arrangement, when the vehicle is just started and / or when the vehicle is running in a cold environment, at least a portion of the first heat exchange channel 141 can be bypassed by controlling the action of the valve core component 31, so that at least a portion of the medium oil can pass through the bypass channel 101, reducing or avoiding the medium oil from passing through the heat exchange component 10 for heat exchange, and reducing the oil consumption of the medium oil, which is conducive to reducing the driving force of the oil pump 50. Alternatively, the bypass channel 101 can be closed by controlling the action of the valve core assembly 31. Through the above arrangement, when the fluid temperature in the thermal management system 2 is high, the oil exchanges heat with the cooling water through the first heat exchange channel 141, thereby facilitating the reduction of the fluid temperature and thereby cooling the electric drive device 61.

[0057] In some embodiments, the thermal management system 2 further includes a second branch, the channel in the second branch is connected to the second heat exchange channel 142 in the heat exchange assembly 10, the fluid in the second heat exchange channel 142 does not interact with the fluid in the first heat exchange channel 141, and the fluid in the second heat exchange channel 142 can exchange heat with the fluid in the first heat exchange channel 141. The second branch may also include a heat exchanger to facilitate heat exchange of structures such as batteries in the vehicle. The fluid in the second heat exchange channel 142 does not interact with the fluid in the first heat exchange channel 141, and the fluid in the second heat exchange channel 142 can exchange heat with the fluid in the first heat exchange channel 141. Through the above arrangement, the fluid in the second heat exchange channel 142 can cool the fluid in the first heat exchange channel 141, so that the fluid such as the dielectric oil flowing out of the first heat exchange channel 141 dissipates heat from the electric drive device 61.

[0058] In order to reduce the occupied space of the thermal management system 2 and facilitate the function of bypassing the heat exchange component 10, the Figure 2 , Fig.14 , Fig. 27 as well as Fig.34In the embodiment of the present invention, the integrated device 1 has a bypass channel 101, a valve cavity 102 and an inlet 103. The integrated device 1 includes a heat exchange component 10, a connection component 20 and a valve core component 31. At least part of the valve core component 31 is located in the valve cavity 102. The heat exchange component 10 has a communication port P3 and a first fluid outlet P2. The communication port P3 is located upstream of the first fluid outlet P2. The connection component 20 is sealed and connected to the heat exchange component 10. The connection component 20 covers the communication port P3. The connection component 20 forms the bypass channel 101. , and the connecting assembly 20 forms at least a portion of the wall of the valve cavity 102; wherein, the inlet 103 is located upstream of the connecting port P3, and the inlet 103 is located in one of the connecting assembly 20 and the heat exchange assembly 10, the connecting assembly 20 also has a first conduction port P5 and a second conduction port P6, the first conduction port P5 is connected to the connecting port P3, and the second conduction port P6 is connected to the bypass channel 101, and the valve core assembly 31 is configured to be able to connect the first conduction port P5 and the second conduction port P6 to the inlet 103. In this article, one of the ports is located upstream of the other port means that along the flow direction of the fluid, the fluid flows from the port located upstream to the port located downstream. Through the above-mentioned arrangement, it is convenient to bypass at least part of the first heat exchange channel 141 through the bypass channel 101, so as to reduce the loss of the fluid flowing in the integrated device 1 in a low-temperature environment.

[0059] In some embodiments, the connection assembly 20 further has an outlet 104, which is connected to the other end of the bypass channel 101. The connection assembly 20 can cover the first fluid outlet P2, and the outlet 104 is connected to the first fluid outlet P2 or the outlet 104 coincides with the first fluid outlet P2, and the first heat exchange channel 141 is connected to the first fluid outlet P2 and the connecting port P3. Through the above arrangement, the oil flowing out of the bypass channel 101 and the first fluid outlet P2 can flow out of the integrated device 1 through the outlet 104.

[0060] See also Figures 2 to 13 As shown, in one embodiment of the integrated device 1, the heat exchange component 10 has a first fluid inlet P1, a first fluid outlet P2 and a first heat exchange channel 141. The first fluid inlet P1 and the first fluid outlet P2 are connected through the first heat exchange channel 141. The first fluid inlet P1 is located upstream of the first fluid outlet P2. At this time, the first fluid inlet P1 can coincide with the connecting port P3. The connecting component 20 is sealed and connected to the heat exchange component 10, and the connecting component 20 covers the first fluid inlet P1. The inlet 103 and the outlet 104 of the integrated device 1 can both be located in the connecting component 20. The inlet 103 can be connected to the first pump port 51 of the oil pump 50. The medium oil flowing out of the first pump port 51 of the oil pump 50 can enter the integrated device 1 through the inlet 103. The first pump port 51 can serve as the outlet of the oil pump 50.

[0061] Furthermore, the connection assembly 20 also has a third connection port P7, the first conduction port P5 is connected to the first fluid inlet P1, the second conduction port P6 is connected to one end of the bypass channel 101, and the third connection port P7 is connected to the inlet 103. The valve core assembly 31 is configured to selectively connect at least one of the first conduction port P5 and the second conduction port P6 to the third connection port P7. Through the above arrangement, the inlet 103 can be connected to at least one of the bypass channel 101 and the first heat exchange channel 141 through the valve core assembly 31. When the integrated device 1 of the embodiment of the invention is applied to the thermal management system 2 of the vehicle, for example, when the vehicle is just started or the vehicle is running in a cold environment, the valve core assembly 31 can be controlled to connect the inlet 103 to the bypass channel 101, or the valve core assembly 31 can be controlled to connect the inlet 103 to both the bypass channel 101 and the first heat exchange channel 141, so as to reduce or avoid oil from entering the first heat exchange channel 141 of the heat exchange assembly 10. When the fluid temperature returns to the temperature threshold, the valve core assembly 31 can be controlled to connect the inlet 103 with the first heat exchange channel 141, so as to facilitate heat exchange of the oil through the heat exchange assembly 10. In other embodiments, the thermal management system 2 can also be used in other devices such as air conditioners.

[0062] Combination Figures 1 to 5 In some embodiments, the first fluid inlet P1 and the first fluid outlet P2 are located on the same side of the heat exchange component 10, the connecting component 20 covers the first fluid outlet P2, the first conducting port P5 is at least partially opposite to the first fluid inlet P1, and the opening of the outlet 104 close to the side of the heat exchange component 10 is at least partially opposite to the first fluid outlet P2. Through the above arrangement, the loss of the medium oil when it circulates between the connecting component 20 and the heat exchange component 10 can be reduced.

[0063] In some other embodiments, the first fluid inlet P1 and the first fluid outlet P2 can be located on different sides of the heat exchange component 10, and the first fluid inlet P1 and the first fluid outlet P2 can be arranged on both sides of the height direction of the heat exchange component 10. In this case, the connecting component 20 can include a connecting pipe, which connects the port of the bypass channel 101 with the first fluid outlet P2, and the outlet 104 can be located on the connecting pipe.

[0064] Further reading Figures 2 to 13In some embodiments, the heat exchange assembly 10 includes a first side plate 11, a second side plate 12, and a heat exchange core 13 located between the first side plate 11 and the second side plate 12. The heat exchange core 13 includes a plurality of stacked heat exchange plates 131. The inter-plate channel TD3 of the first heat exchange channel 141 can be located between adjacent heat exchange plates 131, and the inter-plate channel of the second heat exchange channel 142 can be located between adjacent heat exchange plates 131. The first fluid inlet P1 and the first fluid outlet P2 are both located on the first side plate 11, and the refrigerant inlet and the refrigerant outlet can both be located on the second side plate 12. The second heat exchange channel 142 of the heat exchange assembly 10 is isolated from the first heat exchange channel 141, and the second heat exchange channel 142 and the first heat exchange channel 141 are heat-conductingly arranged, and the second heat exchange channel 142 and the bypass channel 101 are isolated. In this article, the isolation of the two channels means that the two channels are not connected, and the fluids flowing in the two channels cannot interact.

[0065] Based on this, in order to facilitate the circulation of the refrigerant, the integrated device 1 may further include a connecting pipe portion 15 , the connecting pipe portion 15 is sealed with the second side plate 12 , and the flow channel in the connecting pipe portion 15 is connected with the second heat exchange channel 142 .

[0066] Further, the connection assembly 20 includes a first connection member 23, and the first connection member 23 is sealed and connected to the first side plate 11, so as to reduce the leakage of the fluid when the medium flows between the first connection member 23 and the heat exchange assembly 10. The first connection member 23 and the first side plate 11 jointly define at least part of the wall of the bypass channel 101. In a specific implementation, the first connection member 23 has a groove structure, and the first side plate 11 and the first connection member 23 are sealed and arranged, and the first side plate 11 covers the groove structure to form the bypass channel 101. Through the above arrangement, it is convenient to simplify the structure of the first connection member 23.

[0067] Or, if Figures 6 to 9 As shown, the first connecting member 21 defines the peripheral wall portion of the bypass channel 101, and the connecting assembly 20 includes a plugging cover 27, which is sealed with the first connecting member 23, and the plugging cover 27 is sealed on the side of the bypass channel 101 away from the second conducting port P6. Through the above arrangement, the bypass channel 101 is formed in the connecting assembly 20, which is convenient for reducing leakage of the bypass channel 101.

[0068] In order to realize the action of the valve core assembly 31, in some embodiments, the valve assembly 30 further includes a driving assembly 32, wherein the driving assembly 32 includes a driving member 320, which may be a motor or a combination of a motor and a reduction structure, and the driving member 320 is connected to the valve core shaft of the valve core assembly 31 by transmission, wherein the driving member 320 and the valve core shaft of the valve core assembly 31 are connected by transmission in the following manners, but not limited to: for example, the driving member 320 and the valve core shaft may be interference fit, or connected by a key, or meshed by a toothed shape, or a non-circular shaped hole is provided on one of the driving member 320 and the valve core shaft of the valve core assembly 31, and a shaped shaft segment matching the shaped hole is provided on the other, and the shaped shaft segment is embedded in the shaped hole for clearance fit. Through the above-mentioned arrangement, the driving member 320 can drive the valve core assembly 31 to move, so that the integrated device 1 can switch between different working modes, so that the thermal management system can adapt to different working environments.

[0069] Optionally, the driving component 32 may also include a control component such as a circuit board, and the control component may control the rotation of the driving component 320, so that the driving component 320 controls the rotation of the valve core component 31. Through the above arrangement, it is convenient to quickly control the movement of the valve core component 31 through the driving component 32. Compared with the valve core structure made of a material that expands and contracts with heat and contracts to control the opening and closing of the bypass channel, the integrated device 1 of the embodiment of the present invention has a faster response speed and control accuracy.

[0070] Furthermore, if Figures 2 to 8 As shown, the connection assembly 20 also includes a second connection member 26, and the second connection member 26 is connected to the first connection member 23. Specifically, the first connection member 23 includes a first mounting portion 231, and the first mounting portion 231 is located on the side of the first connection member 23 away from the heat exchange assembly 10. Fasteners such as screws are inserted into the first mounting portion 231, and the second connection member 26 is connected to the first connection member 23. Further, the drive assembly 32 is connected to the second connection member 26, and along the axial direction of the valve core assembly 31, the projection of the drive assembly 32 at least partially overlaps with the projection of the heat exchange assembly 10. Through the above arrangement, the installation limit of the drive assembly 32 is facilitated, and the structure of the integrated device 1 is more compact.

[0071] like Figure 6 and Fig.10 As shown, in some embodiments, the outer peripheral surface of the main body of the valve core assembly 31 is a cylindrical surface or a conical surface, and the valve assembly 30 further includes a first sealing portion 391, which is located between the side wall defining the valve cavity 102 and the valve core assembly 31, and the first sealing portion 391 surrounds the valve core assembly 31. Through the above arrangement, it is convenient to reduce the leakage of oil in the valve cavity 102 to the outside of the valve cavity 102.

[0072] In a specific implementation, at least one of the valve core assembly 31 and the first connecting member 23 includes a groove structure, a portion of the first sealing portion 391 is limitedly disposed in the groove structure, and along the radial direction of the valve core assembly 31, the first sealing portion 391 is sandwiched between the side wall defining the valve cavity 102 and the circumferential wall surface of the valve core assembly 31, so as to reduce the leakage of the integrated device 1 at the corresponding position of the valve assembly 30. For example Fig.10 In the embodiment, the valve core assembly 31 has a mounting groove 314 , and the mounting groove 314 surrounds the rotation axis of the valve core assembly 31 . The first sealing portion 391 can be limitedly disposed in the mounting groove 314 .

[0073] In order to further improve the sealing performance of the integrated device 1 and reduce the internal leakage of the integrated device 1 at the corresponding position of the valve assembly 30, as shown in FIG. Figure 7 As shown, in some embodiments, the integrated device 1 includes a second sealing portion 392 , and along the radial direction of the valve core assembly 31 , the second sealing portion 392 is located between the wall defining the valve cavity 102 and the valve core assembly 31 .

[0074] Alternatively, in some other embodiments, since a small amount of internal leakage of the valve assembly 30 has little effect on whether the heat exchange assembly 10 is bypassed by the bypass channel 101, in order to simplify the structure of the integrated device 1, in some embodiments, as shown in Figure 6, the valve core assembly 31 is matched with the wall clearance defining the valve cavity 102. For example, the clearance between the valve core assembly 31 and the wall defining the valve cavity 102 is less than 0.1 mm. In this case, structures such as the second sealing portion 392 can be omitted, so as to reduce the driving force for the rotation of the valve core assembly 31, reduce the number of parts of the integrated device 1, and simplify the structure of the integrated device 1.

[0075] In order to realize the control function of the valve assembly 30 on the fluid flow path, in some embodiments, the valve core assembly 31 can rotate, and the valve core assembly 31 has a conduction cavity 310, and the conduction cavity 310 can connect at least one of the first conduction port P5 and the second conduction port P6 with the third communication port P7. Optionally, the fluid cross-sectional area of ​​the conduction cavity 310 is uniformly set. Fig.10 As shown, the conducting cavity 310 can be a groove structure recessed from the outer wall of the valve core assembly 31 toward the interior of the valve core assembly 31 , and along the axial direction of the valve core assembly 31 , the groove structure for limiting the first sealing portion 391 is spaced apart from the conducting cavity 310 .

[0076] Combining the above possible implementation methods, such as Fig.11 and Fig.12 As shown, in some embodiments, the integrated device 1 has at least one of the following working modes:

[0077] In the first working mode of the integrated device 1, the valve core assembly 31 is located in the first position, the valve core assembly 31 connects the first conducting port P5 and the second conducting port P6 with the inlet 103, the third connecting port P7 is connected with the first conducting port P5, the third connecting port P7 is connected with the second conducting port P6, the inlet 103 is connected with the outlet 104 through the valve core assembly 31 and the bypass channel 101, and the inlet 103 is connected with the outlet 104 through the valve core assembly 31, the first fluid inlet P1 (connecting port P3), and the first heat exchange channel 141. When the integrated device 1 is applied to the thermal management system 2, the thermal management system 2 is in the first working mode. In the first working mode, the medium oil flowing out from the first pump port 51 of the oil pump 50 is divided into two paths after passing through the inlet 103. One path of the fluid passes through the valve core assembly 31 and the bypass channel 101 and then flows out from the outlet 104, and the other path of the fluid passes through the valve core assembly 31 and the first heat exchange channel 141 and then flows out from the outlet 104. At this time, the heat exchange assembly 10 can be partially bypassed, which is defined as a partial bypass mode.

[0078] Furthermore, if Fig.11 As shown, in the second working mode of the integrated device 1, the valve core assembly 31 is located in the second position, the third connecting port P7 is connected to the first conducting port P5, and the valve core assembly 31 closes the second conducting port P6. At this time, the inlet 103 is connected to the outlet 104 through the valve core assembly 31, the first fluid inlet P1, and the first heat exchange channel 141. When the integrated device 1 is applied to the thermal management system 2, the thermal management system 2 is in the second working mode at this time. In this second working mode, the medium oil flowing out of the first pump port 51 of the oil pump 50 flows out from the outlet 104 after passing through the inlet 103, the valve core assembly 31, and the first heat exchange channel 141, and the medium oil rarely flows through the bypass channel 101. In this article, the valve core assembly 31 closes the connecting port, which means that the fluid cannot flow out of the connecting port or the fluid flowing out of the connecting port is very little. In the first working mode of the integrated device 1, the medium oil can exchange heat with the refrigerant and then dissipate heat to the electric drive device 61.

[0079] like Fig.12As shown, in the third working mode of the integrated device 1, the valve core assembly 31 is located at the third position, the third connecting port P7 is connected to the second conducting port P6, and the valve core assembly 31 closes the first conducting port P5. At this time, the inlet 103 is connected to the outlet 104 through the valve core assembly 31 and the bypass channel 101. At this time, the heat exchange assembly 10 can be completely bypassed, and this is defined as the full bypass mode. When the integrated device 1 is applied to the thermal management system 2, the thermal management system 2 is in the third working mode at this time. In this third working mode, the medium oil flowing out of the first pump port 51 of the oil pump 50 passes through the inlet 103, the valve core assembly 31, and the bypass channel 101 and then flows out from the outlet 104. The medium oil rarely flows through the first heat exchange channel 141, which is convenient for reducing the pressure loss caused by the fluid flowing through the first heat exchange channel 141.

[0080] Please read further Figure 1 , Figures 14 to 25 As shown, the embodiment of the present invention also provides another integrated device 1, which can be applied to Figure 1 The thermal management system is shown.

In other embodiments, the first valve port part P4a and the second valve port part P4b can both be located between the first valve core part 311 and the second valve core part 312. When the valve core assembly 31 moves to the point where the first valve core part 311 abuts against the first valve port part P4a, and there is a gap between the second valve core part 312 and the second valve port part P4b, at this time, the first valve port P41 is in a closed state, and the second valve port P42 is in an open state. When the valve core assembly 31 moves to the point where there is a gap between the first valve core part 311 and the first valve port part P4a, and the second valve core part 312 abuts against the second valve port part P4b, at this time, the first valve port P41 is in an open state, and the second valve port P42 is in a closed state.

[0102] In some embodiments, the integrated device 1 has at least one of the following working modes:

[0103] In the first working mode of the integrated device 1, the valve core assembly 31 is located in the first position, there is a gap between the first valve core portion 311 and the first valve port portion P4a, there is a gap between the second valve core portion 312 and the second valve port portion P4b, the inlet 103 is connected to the outlet through the third connecting port P7, the second valve port P42, the first conducting port P5, the first fluid inlet P1, and the first heat exchange channel 141, and the inlet 103 is connected to the outlet through the third connecting port P7, the first valve port P41, the second conducting port P6, and the bypass channel 101.

At this time, the first heat exchange channel 141 and the bypass channel 101 are arranged in parallel. Through the above arrangement, when the vehicle is just started and / or when the vehicle is running in a cold environment, the action of the valve core assembly 31 is controlled to bypass at least part of the first heat exchange channel 141, so that at least part of the medium oil can pass through the bypass channel 101, reduce or avoid the medium oil from passing through the heat exchange assembly 10 for heat exchange, and reduce the oil consumption of the medium oil, which is conducive to reducing the driving force of the oil pump 50.

[0109] In order to reduce the occupied space of the thermal management system 2 and facilitate the function of bypassing at least part of the first heat exchange channel 141, please refer to Figures 2 to 8 The embodiment of the present invention further provides an integrated device 1, which has a bypass channel 101, a valve cavity 102 and a third valve port P43. The integrated device 1 includes a heat exchange component 10, a connection component 20 and a valve component 30.

Through the above arrangement, when the integrated device 1 is applied to the thermal management system 2, and the fluid temperature in the thermal management system 2 is low, the connecting port and the valve port can be connected by controlling the relative movement of the valve core component 31 and the third valve port P43, and at this time, the bypass channel can bypass part of the first heat exchange channel, so as to reduce the pressure loss of the oil medium when passing through the integrated device.

[0111] To facilitate the circulation of the medium oil in the integrated device 1, in some embodiments, the heat exchange assembly 10 further has a first fluid outlet P2, the first fluid inlet P1 and the first fluid outlet P1 are located on the outer surface of the integrated device 1, and the fluid can enter the integrated device 1 through the first fluid inlet P1 and flow out of the integrated device from the first fluid outlet P2. The first heat exchange channel 141 also includes a second corner hole channel TD2 and an inter-plate channel TD3, the inter-plate channel TD3 connects the first corner hole channel TD1 and the second corner hole channel TD2, the first fluid inlet P1 is connected to the connecting port P3 through the first corner hole channel TD1, the first fluid outlet P2 is located downstream of the connecting port P3, and the first fluid outlet P2 is connected to the second corner hole channel TD2.

[0112] Based on this, the integrated device 1 has a first working mode, as shown in 29. In the first working mode, there is a gap between the valve core assembly 31 and the wall portion defining the third valve port P43, and the connecting port P3 is connected to the third valve port P43. On the one hand, the first fluid inlet P1 is connected to the first fluid outlet P2 through the first corner hole channel TD1, the second corner hole channel TD2 and the inter-plate channel TD3; on the other hand, the first fluid inlet P1 is also connected to the first fluid outlet P2 through the first corner hole channel TD1, the connecting port P3, the valve cavity 102, the third valve port P43, the bypass channel 101, and the second corner hole channel TD2. At this time, the bypass channel 101 is arranged in parallel with the inter-plate channel TD3. Through the above-mentioned arrangement, when the medium oil flows into the heat exchange component 10, since the flow resistance of the inter-plate channel TD3 is relatively large and the flow resistance of the valve cavity 102 and the bypass channel 101 is relatively small, most of the medium oil will flow into the valve cavity 102, and flow from the bypass channel 101 to the second corner hole channel TD2, and then flow out from the first fluid inlet P1, which is beneficial to reducing the flow path of the fluid in the heat exchange component 10, and in the first working mode of the integrated device 1, it is beneficial to reduce the driving power consumption of the oil pump 50.

[0113] As shown in Figure 29, in a specific implementation, the valve core assembly 31 moves in a direction away from the third valve port P43 so that there is a gap between the valve core assembly 31 and the wall portion defining the third valve port P43.

In the second working mode, the valve core assembly 31 abuts against the wall that defines the third valve port P43, and the first fluid inlet P1 is connected to the first fluid outlet P2 and the outlet 104 through the first heat exchange channel 141.

[0129] Furthermore, in order to reduce the number of parts and save costs, the structure of the integrated device 1 is simplified.

[0130] Specifically, combined Figure 34 to Figure 39In an embodiment of the present invention, the connection component 20 includes a first connection member 23 and a valve body 24 that are sealed and connected. The first connection member 23 is a transfer tube structure. For example, the first connection member 23 can be a bent tube structure.

[0131] Specifically, in Figures 27 to 39 In the integrated device 1 shown, the second side plate 12 has a connecting port P3 and a transfer port P8, the connecting port P3 is connected to the first fluid inlet P1 through the first corner hole channel TD1, the transfer port P8 is connected to the first fluid outlet P2 through the second corner hole channel TD2, one end of the bypass channel 101 is connected to the second conducting port P6, and the other end is connected to the transfer port P8.

[0132] Furthermore, combined with Figure 34 to Figure 39 The integrated device 1 also includes a drive component 32, which is connected to Figures 27 to 33 Specifically, the drive assembly 32 includes a drive shell 321. To achieve the limit position between the drive assembly 32 and the valve body 24, in some embodiments, a portion of the drive shell 321 is sleeved inside the valve body 24.

Correspondingly, the clamping member 33 includes a limiting portion 331 and a main body 332. The inner wall surface of the limiting portion 331 is closer to the center of the clamping member 33 than the inner wall surface of the main body 332. The main body 332 is limited in the limiting groove 245, and the limiting portion 331 passes through the limiting hole 244 and abuts against the outer wall of the drive shell 321.

[0134] In the embodiment of the present invention, a bypass channel is provided on the flow path side of the first fluid, and / or, in some other embodiments, a bypass channel with a similar structure may also be provided on the flow path side of the second fluid.

[0135] On the other hand, combined with Fig.40As shown, an embodiment of the present invention further provides a control method of a thermal management system, which is used to control the thermal management system 2 of any of the above embodiments, wherein the thermal management system 2 includes a first branch 40, the first branch 40 is located upstream of the oil pump 50, and the channel in the first branch 40 is connected to the channel in the oil pump 50, as shown in FIG. Fig.14 As shown, the control method of the thermal management system includes:

[0136] Step S110, comparing the temperature of the fluid in the first branch 40 with the temperature threshold, and obtaining a first comparison result that the temperature of the fluid in the first branch 40 is less than or equal to the temperature threshold;

[0137] Step S120 , controlling the valve core assembly 31 to operate according to the first comparison result, so that the valve core assembly 31 connects both the first conduction port P5 and the second conduction port P6 with the inlet 103 .

[0138] In some embodiments, steps S110 and S120 can enable the integrated device 1 to be in the first working mode. Figures 2 to 12 In the integrated device 1 shown, step S120 is to control the valve core assembly 31 to rotate according to the first comparison result, so that the valve core assembly 31 connects the first conduction port P5 and the second conduction port P6 to the inlet 103. Figures 14 to 25 In the integrated device 1 shown, step S120 is to control the movement of the valve core assembly 31 according to the first comparison result, so that there is a gap between the first valve core part 311 and the first valve port part P41, and there is a gap between the second valve core part 312 and the second valve port part P42. Figures 27 to 39 In the integrated device 1 shown, step S120 is to control the movement of the valve core assembly 31 according to the first comparison result so that there is a gap between the valve core assembly 31 and the wall surface defining the third valve port P43.

[0139] In some embodiments, before step S110, a step of detecting the temperature of the fluid in the first branch 40 may be further included. Optionally, the temperature threshold may be 40°C. When the temperature of the fluid in the first branch 40 is less than or equal to 40°C, the temperature of the fluid is relatively low, and the electric drive device 61 may be heat exchanged. At this time, the oil medium may not need to pass through the heat exchange component 10 to exchange heat with the oil medium. When the fluid temperature exceeds 40°C, the fluid temperature is relatively high, and the oil medium needs to be cooled by the heat exchange component 10 to better cool the electric drive system. In some other specific embodiments, the temperature threshold may be set according to user needs, for example, it may be 35°C, 30°C, 41°C, 42°C, etc., and the present invention is not limited thereto.

[0140] The first branch 40 includes a structure such as an oil tank, and the medium oil is stored in the oil tank. By comparing the fluid temperature in the first branch 40 with the temperature threshold, the valve core assembly 31 can be better controlled according to the operating environment of the vehicle, thereby cooling or not cooling the fluid temperature, improving the pressure loss of the oil medium, and facilitating the reduction of the driving force of the oil pump 50.

[0141] Exemplarily, the first branch 40 may also include a temperature sensor, which can be used to detect the fluid temperature in the first branch 40. For example, the temperature sensor can detect the fluid temperature of the fuel tank. The temperature sensor can feed back the detected fluid temperature result to the electronic control unit (ECU), where the electronic control unit can be a control system of an automobile engine, and the ECU controls the action of the valve core assembly 31 to facilitate improving the response speed of the valve core assembly 31.

[0142] Furthermore, for Figures 2 to 12 The integrated device 1 shown and Figures 14 to 25 For the integrated device 1 shown, in some embodiments, the control method of the thermal management system includes:

[0143] Step S111, comparing the temperature of the fluid in the first branch 40 with a temperature threshold, and obtaining a first comparison result that the temperature of the fluid in the first branch 40 is less than or equal to the temperature threshold;

[0144] Step S121 , controlling the valve core assembly 31 to move according to the first comparison result, so that the valve core assembly 31 connects the second communication port P6 with the third communication port P7 , and closes the first communication port P5 .

[0145] In some embodiments, step S111 and step S121 can place the integrated device 1 in the third working mode. Through the above settings, the oil medium can be prevented or reduced from entering the heat exchange component 10, which is convenient for quickly increasing the fluid temperature and reducing the loss of the oil pump 50.

[0146] Optionally, the temperature threshold may include a first temperature threshold and a second temperature threshold, and the second temperature threshold is greater than the first temperature threshold. In this case, the control method of the thermal management system includes:

[0147] Step 1, comparing the temperature of the fluid in the first branch 40 with a temperature threshold, and obtaining a first result that the temperature of the fluid in the first branch 40 is less than or equal to the first temperature threshold;

[0148] Step 2: Control the valve core assembly 31 to operate according to the first result, so that the valve core assembly 31 connects the second conducting port P6 with the third communication port P7.

[0149] Step 3, comparing the temperature of the fluid in the first branch 40 with the temperature threshold, and obtaining a second result that the temperature of the fluid in the first branch 40 is greater than the first temperature threshold and less than or equal to the second temperature threshold;

[0150] Step 4: Control the valve core assembly 31 to operate according to the first result, so that the valve core assembly 31 connects the first conduction port P5 and the second conduction port P6 with the third communication port P7.

[0151] In a specific implementation, the first temperature threshold can be equal to the second temperature threshold, that is, when the fluid temperature in the first branch 40 is less than or equal to the temperature threshold, for example, when the fluid temperature in the first branch 40 is less than or equal to 40°C, the user can control the action of the valve core assembly 31 as needed to achieve a partial bypass mode or a full bypass mode of the thermal management system.

[0152] Furthermore, combined with Figures 1 to 39 In a possible implementation, in some embodiments, the control method of the thermal management system includes:

[0153] Step S112, comparing the temperature of the fluid in the first branch 40 with the temperature threshold, and obtaining a second comparison result that the temperature of the fluid in the first branch 40 is greater than the temperature threshold;

[0154] Step S122, control the action of the valve core assembly 31 according to the second comparison result, so that the valve core assembly 31 connects the first conducting port P5 with the third connecting port P7, and the valve core assembly 31 closes the second conducting port P6. At this time, the integrated device 1 is in the second working mode, the valve core assembly 31 closes the second conducting port P6, and the inlet 103 is connected with the outlet 104 through the first heat exchange channel 141.

[0155] Through the above arrangement, when the fluid temperature in the first branch 40 is greater than the temperature threshold, the action of the valve core assembly 31 is controlled so that the medium oil flows through the heat exchange assembly 10 for heat exchange, thereby cooling the medium oil and facilitating cooling of the electric drive device 61.

[0156] It should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention, such as the directional definitions of "front", "back", "left", "right", "up" and "down".
