Description

Technical Field

[0001] This utility model relates to the technical field of new energy vehicles, and more specifically, to a thermal management module for new energy vehicles. Background Technology

[0002] With the booming development of the new energy vehicle industry, the thermal management module of new energy vehicles is one of the key technologies to ensure vehicle performance, safety, and driving comfort. Compared with traditional fuel vehicles, new energy vehicles have more heat sources and higher temperature control requirements due to the addition of components such as power batteries, drive motors, and electronic control systems. Therefore, the thermal management module not only needs to meet the needs of traditional air conditioning systems, but also needs to solve the problems of efficient heat dissipation and temperature control of components such as batteries and motors.

[0003] Currently, vehicle thermal management modules typically include core components such as water heaters, evaporators, and four-way valves. Among these, the four-way valve is the control component for the refrigerant flow direction in the thermal management module, consisting of a valve core and a drive motor for controlling the rotation of the valve core. Traditional four-way valves usually have the valve core and drive motor installed in the same mounting space to simplify the assembly process.

[0004] However, there is at least one problem with the relevant technology: the four-way valve in the prior art usually installs the valve core and the drive motor in the same installation space. However, when the thermal management system is in the cooling condition for a long time, the heat generated by the drive motor when it is working will accumulate in the installation space between the valve core and the drive motor, which will cause the temperature in the installation space to rise, thereby affecting the heat exchange effect of the refrigerant inside the valve core, and thus affecting the heat exchange effect of the thermal management module. Utility Model Content

[0005] The technical problem solved by this utility model is that in the prior art, the four-way valve usually installs the valve core and the drive motor in the same installation space. However, when the thermal management system is in the cooling condition for a long time, the heat generated by the drive motor during operation will accumulate in the installation space between the valve core and the drive motor, causing the temperature in the installation space to rise, thereby affecting the heat exchange effect of the refrigerant inside the valve core, and thus affecting the heat exchange effect of the thermal management module.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 14As shown, this utility model provides a thermal management module for a new energy vehicle. The thermal management module includes a housing 100, which is provided with a four-way valve mechanism 200 and a four-way valve mounting cavity 110 for mounting the four-way valve mechanism 200. The four-way valve mounting cavity 110 includes a first cavity and a second cavity arranged adjacent to each other. The four-way valve mechanism 200 includes a valve core 210, a drive assembly 300, and a valve stem shaft 220. Specifically, the valve core 210 is mounted in the first cavity, and the drive assembly 300 is mounted in the second cavity to drive the valve core 210 to rotate. One end of the valve stem shaft 220 is connected to the valve core 210, and the other end is connected to the drive assembly 300 for transmission. A shaft hole 111 is provided between the first cavity and the second cavity for the valve stem shaft 220 to pass through, so that one end of the valve stem shaft 220 is located in the first cavity and the other end is located in the second cavity.

[0032] Specifically, this solution achieves high integration within the four-way valve mechanism 200 by placing the valve core 210 in the first cavity, the drive assembly 300 in the second cavity, and using the valve stem shaft 220 passing through the shaft hole 111 for transmission. This avoids the accumulation of heat generated by the drive assembly 300 in the four-way valve mounting cavity 110 when the thermal management module is in cooling mode for a long time, which would cause the temperature inside the four-way valve mounting cavity 110 to rise. This improves the heat exchange effect of the refrigerant inside the valve core 210, thereby enhancing the heat exchange effect of the thermal management module.

[0033] In one example of this utility model, such as Figures 2 to 5 As shown, the four-way valve mechanism 200 includes a bushing 221 and a sealing ring 222. Specifically, the bushing 221 is sleeved on the outside of the valve stem shaft 220 so that the valve stem shaft 220 is rotatably engaged with the shaft hole 111, and the sealing ring 222 is sleeved on the outside of the valve stem shaft 220 and is located between the bushing 221 and the valve core 210.

[0034] In one example of this utility model, such as Figures 1 to 14 As shown, a first cavity is disposed on top of a second cavity, and a first opening is provided on the top of the first cavity. The four-way valve mechanism 200 also includes a first cover 230 and a second cover 240. Specifically, the first cover 230 is detachably installed on the top of the first cavity to cover the first opening, and the second cover 240 is detachably connected to the bottom wall of the first cavity. The second cavity is formed between the second cover 240 and the bottom wall. A first mounting groove 241 is provided on the side of the second cover 240 near the first cavity, and the drive assembly 300 is installed in the first mounting groove 241.

[0035] Specifically, firstly, this solution provides a first cover 230 that is detachably installed on the top of the first cavity, facilitating the disassembly and assembly of the first cover 230 by maintenance personnel, thereby improving the convenience of maintenance of the valve core 210; secondly, by providing a second cover 240 that is detachably connected to the bottom wall of the first cavity, maintenance personnel can easily disassemble and assemble the second cover 240 when maintaining the drive assembly 300, thereby improving the convenience of maintenance of the drive assembly 300.

[0036] In one example of this utility model, such as Figures 2 to 7 As shown, a sealing groove 244 is provided circumferentially on the side of the second cover 240 near the first cavity. A first sealing element 245 is installed in the sealing groove 244. When the second cover 240 is fixedly connected to the bottom wall, the upper end face of the first sealing element 245 abuts against the bottom wall, and the lower end face of the first sealing element 245 abuts against the sealing groove 244.

[0037] Furthermore, such as Figure 6 and Figure 7 As shown, the sealing groove 244 includes a first inner sidewall and a second inner sidewall disposed opposite to each other. The first sealing member 245 is located between the first inner sidewall and the second inner sidewall. The first sealing member 245 is provided with a plurality of protrusions along the circumference, and the plurality of protrusions are arranged at intervals therein. Each protrusion includes a first protrusion protruding towards the first sealing member 245 near the first inner sidewall and a second protrusion protruding towards the first sealing member 245 near the second inner sidewall. When the first sealing member 245 is installed in the sealing groove 244, the protrusion abuts against the first inner sidewall, and the second protrusion abuts against the second inner sidewall, thereby improving the sealing performance when the second cover 240 is fitted with the bottom wall.

[0038] In one example of this utility model, such as Figures 1 to 13 As shown, the first cover 230 is provided with a first limiting part 231a and a second limiting part 231b on the side near the first cavity; the valve core 210 is provided with a positioning protrusion 211 on the top; wherein, when the first cover 230 is installed on the top of the first cavity, the positioning protrusion 211 is located between the first limiting part 231a and the second limiting part 231b.

[0039] Specifically, this solution achieves precise control of the rotation angle of the valve core 210 by setting a positioning protrusion 211 to cooperate with the first limiting part 231a and the second limiting part 231b, and provides hard stop protection for the valve core 210 between the first limiting part 231a and the second limiting part 231b.

[0040] In one example of this utility model, such as Figures 5 to 13As shown, the first cover 230 has an arc-shaped protrusion 231 on the side near the first cavity, and the arc-shaped protrusion 231 has a second opening, with the two ends of the second opening being a first limiting part 231a and a second limiting part 231b, respectively. When the first cover 230 is installed on the top of the first cavity, the positioning protrusion 211 is located in the second opening. When the driving assembly 300 drives the valve core 210 to rotate, the positioning protrusion 211 limits the rotation between the first limiting part 231a and the second limiting part 231b, and causes the valve core 210 to form a 90° back-and-forth limiting rotation.

[0041] In one example of this utility model, such as Figures 1 to 5 As shown, the drive assembly 300 includes a drive motor 310, a first transmission gear set 320, a second transmission gear set 330, and an output gear 340. Specifically, the drive motor 310 is provided with a drive shaft to provide driving force to the valve stem shaft 220. The first transmission gear set 320 is drivenly connected to the drive shaft, the second transmission gear set 330 is drivenly connected to the first transmission gear set 320, and the output gear 340 is drivenly connected between the second transmission gear set 330 and the valve stem shaft 220.

[0042] Specifically, this solution sets the first transmission gear set 320, the second transmission gear set 330, and the output gear 340 to cooperate with the drive shaft of the drive motor 310, so as to transmit the driving force of the drive motor 310 to the valve core 210, control the valve core 210 to rotate, and change the flow direction of fluid in multiple ports.

[0043] In one example of this utility model, such as Figures 1 to 5 As shown, the second cover 240 has a first mounting position 242 and a second mounting position 243 on the side near the first cavity shown; the first transmission gear set 320 includes a first rotating shaft 321, a first transmission gear 322 and a second transmission gear 323; the second transmission gear set 330 includes a second rotating shaft 331, a third transmission gear 332 and a fourth transmission gear 333. Specifically, the first rotating shaft 321 is installed at the first mounting position 242, the first transmission gear 322 is sleeved on the outside of the first rotating shaft 321, the second transmission gear 323 is sleeved on the outside of the first rotating shaft 321 and located at the bottom of the first transmission gear 322, the second rotating shaft 331 is installed at the second mounting position 243, the third transmission gear 332 is sleeved on the outside of the second rotating shaft 331, and the fourth transmission gear 333 is sleeved on the outside of the second rotating shaft 331 and located at the top of the third transmission gear 332; wherein, the first transmission gear 322 and the second transmission gear 323 are integrally formed, and the third transmission gear 332 and the fourth transmission gear 333 are integrally formed.

[0044] Specifically, this solution integrates the first transmission gear 322 and the second transmission gear 323, enabling them to rotate coaxially to ensure the synchronicity of their rotation. Similarly, it integrates the third transmission gear 332 and the fourth transmission gear 333, ensuring their synchronicity of rotation.

[0045] In one example of this utility model, such as Figures 1 to 14 As shown, the housing 100 is also provided with a first receiving cavity 120 and a second receiving cavity 130 arranged adjacent to each other.

[0046] Specifically, this solution improves the integration of the thermal management module of new energy vehicles by stacking the evaporation mechanism 500, the heating mechanism 400, and the electronic control board 131, thereby reducing the cost of new energy vehicles.

[0047] In one example of this utility model, such as Figures 1 to 12 As shown, the thermal management module also includes a first drive interface 140, which is located at the first end of the housing 100 near the four-way valve mounting cavity 110; and a second drive interface 150, which is located at the first end and adjacent to the first drive interface 140. The first drive interface 140 is electrically connected to the drive assembly 300 and to the electronic control board 131; the second drive interface 150 is also electrically connected to the electronic control board 131. This solution further reduces the cost of the thermal management module.

[0048] Specifically, in the prior art, the heater and the four-way valve are separate components in the thermal management module, requiring the design of two circuit boards and two low-voltage interfaces. In this embodiment, the drive component 300 is electrically connected to the control board 131, and only one first drive interface 140 needs to be set up to connect to the drive component 300 to achieve unified control of the heating mechanism 400 and the four-way valve mechanism 200, thereby further reducing the cost of the thermal management module.

[0049] In a specific example of this utility model, such as Figure 11 and Figure 12As shown, a first terminal block 246 is provided on the side of the second cover 240 away from the first cavity; wherein, the end of the first terminal block 246 away from the second cover 240 is connected to the first drive interface 140 by a plug-in manner to realize the electrical connection between the drive assembly 300 and the first drive interface 140; a second terminal block 247 is welded on the side of the electronic control board 131 away from the first cavity, and the second terminal block 247 is connected to the second cover 240 by a plug-in manner to realize the electrical connection between the drive assembly 300 and the electronic control board 131, and the electrical connection between the first drive interface 140 and the electronic control board 131.

The first cavity is provided with a first channel 112, a second channel 113, a third channel 114, and a fourth channel 115 along the circumferential direction, and the first channel 112, the second channel 113, the third channel 114, and the fourth channel 115 are spaced apart. The first channel 112 communicates with the first receiving cavity 120, the second channel 113 communicates with the evaporation mechanism 500, the third channel 114 communicates with the first interface 250, and the fourth channel 115 communicates with the second interface 260.

[0051] Specifically, this solution connects the housing 100, heating mechanism 400, evaporation mechanism 500, and four-way valve mechanism 200 by setting a first channel 112 to connect with the first receiving cavity 120, a second channel 113 to connect with the evaporation mechanism 500, a third channel 114 to connect with the first interface 250, and a fourth channel 115 to connect with the second interface 260. This allows the heating mechanism 400, evaporation mechanism 500, and four-way valve mechanism 200 to form an integrated unit within the housing 100, thereby achieving a modular design for the thermal management module. This makes the structure of the entire thermal management module simpler and improves the reliability and integration of the thermal management module in new energy vehicles. Furthermore, during installation, only the entire integrated unit needs to be installed into the vehicle, thus reducing the installation difficulty of the thermal management module.

[0052] In one example of this utility model, such as Figures 1 to 10 As shown, the top of the housing 100 is provided with a second mounting groove 160 for mounting the heating mechanism 400 and a third cover 170. The third cover 170 is detachably mounted on the top of the second mounting groove 160 to form a first receiving cavity 120. The thermal management module also includes a heat insulation plate 600, which is disposed between the third cover 170 and the evaporation mechanism 500 and is connected to the third cover 170 by welding.

[0053] Specifically, this solution involves installing a heat insulation plate 600 between the third cover 170 and the evaporation mechanism 500. This reduces heat transfer from the heating mechanism 400 to the evaporation mechanism 500 when it is in cooling mode, thereby improving the cooling effect of the refrigerant within the evaporation mechanism 500. The heat insulation plate 600 is designed with a perforated shape, reducing the contact area between the evaporation base plate 510 and the third cover 170. This further reduces heat transfer from the heating mechanism 400 to the evaporation mechanism 500 during cooling mode, thus improving the cooling effect of the coolant within the evaporation mechanism 500.

[0054] In one example of this utility model, such as Figures 1 to 10 As shown, the heating mechanism 400 includes at least one heating element 410 and a partition plate 420. Specifically, at least one heating element 410 is installed in the second mounting groove 160, and the at least one heating element 410 is meandering and horizontally arranged. The partition plate 420 is disposed outside the at least one heating element 410, which improves the heat exchange efficiency of the heating mechanism 400. The second mounting groove 160 is also provided with a water inlet 430 for connecting water to the heating mechanism 400.

[0055] In one example of this utility model, such as Figures 1 to 10 As shown, the evaporation mechanism 500 includes an evaporation base plate 510, multiple evaporation intermediate plates 520, an evaporation top plate 530, a water outlet 531, a refrigerant inlet 532, and a refrigerant outlet 533. Specifically, the evaporation base plate 510 is disposed on the top of the third cover 170, the multiple evaporation intermediate plates 520 are disposed on the top of the evaporation base plate 510, the multiple evaporation intermediate plates 520 are vertically stacked, and any two of the multiple evaporation intermediate plates 520 are connected by welding, the evaporation top plate 530 is disposed on the top of the multiple evaporation intermediate plates 520, the water outlet 531 is disposed on the top of the evaporation top plate 530, and the refrigerant inlet 532 is disposed on the top of the evaporation top plate 530 and is adjacent to the water outlet 531. The refrigerant outlet 533 is located on the top of the evaporator top plate 530 and is positioned opposite to the refrigerant inlet 532. The third cover 170 is provided with an evaporation through hole 171 at one end outside the second mounting groove 160 for connecting the evaporation mechanism 500 and the four-way valve. The heat insulation plate 600 is provided with a first through hole 610, the evaporation bottom plate 510 is provided with a second through hole 511, and multiple evaporation intermediate plates 520 are provided with a third through hole 521. The evaporation through hole 171, the first through hole 610, the second through hole 511 and the third through hole 521 are interconnected.

[0056] Specifically, this solution improves the heat exchange efficiency of the evaporation mechanism 500 by setting the evaporation mechanism 500 to include an evaporation base plate 510, a heat insulation plate 600, multiple evaporation intermediate plates 520, an evaporation top plate 530, a water outlet 531, a refrigerant inlet 532, and a refrigerant outlet 533. The third cover 170 is provided with an evaporation through hole 171 for connecting the evaporation mechanism 500 and the four-way valve at one end outside the second mounting groove 160. The heat insulation plate 600 is provided with a first through hole 610, the evaporation base plate 510 is provided with a second through hole 511, and the multiple evaporation intermediate plates 520 are provided with a third through hole 521. The evaporation through hole 171, the first through hole 610, the second through hole 511, and the third through hole 521 are interconnected.

[0057] In one example of this utility model, such as Figures 1 to 8 As shown, the evaporation mechanism 500 is welded to the top of the heating mechanism 400. The second receiving cavity 130 has a second opening on the side away from the first receiving cavity 120. The housing 100 also includes a fourth cover 132. The fourth cover 132 is detachably connected to the housing 100 in a manner such as snap-fit ​​or screw-fit to cover the second opening and seal the control board 131 in the second receiving cavity 130. In this embodiment, the fourth cover 132 is screwed to the housing 100.

[0058] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
