Description

Technical Field

[0001] This application relates to the field of vehicle thermal management, and specifically to a thermal management component. Background Technology

[0002] In new energy vehicles, thermal management components are typically installed to control the temperature of critical vehicle parts. The interior space of a new energy vehicle is a crucial part of the driving and riding experience; therefore, the dimensional requirements for components are relatively high during the design process. Furthermore, during coolant filling, some gas may remain in the thermal management components. If this gas cannot be expelled from multiple locations, it will affect the normal circulation and heat exchange efficiency of the thermal management system. How to remove this gas and achieve miniaturization of the thermal management components is a significant technical challenge. Summary of the Invention

[0003] The purpose of this application is to provide a thermal management component that solves the problem of insufficient compactness in the structure of thermal management components.

[0004] To achieve the above objectives, one embodiment of this application adopts the following technical solution:

[0005] A thermal management component includes a flow channel component, a core, and a housing. The flow channel component and the housing are fixedly connected or integrally formed. The flow channel component has a first flow channel and a second flow channel. The flow channel component has a first connecting port, a second connecting port, a third connecting port, and a fourth connecting port. The first connecting port and the second connecting port communicate with the first flow channel. The third connecting port and the fourth connecting port communicate with the second flow channel. The first flow channel includes a first sub-segment, and the second flow channel includes a second sub-segment. Along the height direction of the thermal management component, the first sub-segment is located above the line connecting the first connecting port and the second connecting port, and the second sub-segment is located above the line connecting the third connecting port and the fourth connecting port.

[0006] The housing has a receiving cavity, and the core is at least partially located in the receiving cavity. The core enables the first sub-segment and the second sub-segment to communicate or not communicate with the outside through the receiving cavity.

[0007] One embodiment of the thermal management component of this application includes a flow channel component, a core, and a housing. The housing is integrally formed with or fixedly connected to the flow channel component. The flow channel component has a first flow channel and a second flow channel. Along the height direction of the thermal management component, the first flow channel has a first segment located above the line connecting the first and second connecting ports, and the second flow channel has a second segment located above the third and fourth connecting ports. The core is at least partially located in the receiving cavity of the housing. The core allows the first and second segments to communicate with or not communicate with the outside through the receiving cavity. The first and second segments are prone to trapping gas. The core allows the gas in the first and second segments to be discharged to the outside through the receiving cavity of the housing. Compared to the exhaust structure of having two flow channels separately on the flow channel component, this application integrates the exhaust structure of the two flow channels into the housing, occupying less space, thereby making the structure of the thermal management component more compact.

[0018] The features and exemplary embodiments of various aspects of the present invention will now be described. To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. In this document, relational terms such as "first" and "second" are used merely to distinguish one component from another that has the same name, and do not necessarily require or imply any such actual relationship or order between these components.

[0019] refer to Figure 1 This application provides a thermal management component with an exhaust structure. The exhaust structure is used to vent the gas in the thermal management component when it is filled with atmospheric pressure. In this embodiment, it is mainly used to vent the gas in the coolant flow channel, as detailed below.

[0020] In this embodiment, the flow channels in the thermal management component have a height difference. In particular, when the flow channel component with multiple flow channels is installed vertically in the vehicle, some gas remains at the high point and cannot be discharged when the coolant is added at normal pressure, which affects the normal circulation and heat exchange efficiency of the entire system. Therefore, the thermal management component in this embodiment includes an exhaust component.

[0021] refer to Figures 1-9 The thermal management component of this application embodiment includes a flow channel component 2 and a housing 11. The flow channel component 2 is not limited to a flow channel plate; it can also be other components with flow channels, such as a block manifold, pump, or kettle. The flow channel component 2 is fixedly connected to the housing 11. The flow channel component 2 has a first flow channel 21 and a second flow channel 22. It is not limited that the first and second flow channels are both located in the same flow channel component. For example, the first flow channel can be located in a flow channel plate, and the second flow channel can be located in other components with flow channels, such as a block manifold, pump, or kettle. In this embodiment, both the first and second flow channels are located in a flow channel plate. The flow channel component 2 has a first connecting port 201, a second connecting port 202, a third connecting port 203, and a fourth connecting port 204. The first connecting port 201, the second connecting port 202, the third connecting port 203, and the fourth connecting port 204 can all be external interfaces located on external pipes, valve ports located on valve mounting parts, etc. The pump inlet or outlet located at the pump mounting section, the connection port located at the kettle, or the connecting port located at the heat exchanger mounting section, etc., the first connecting port 201 and the second connecting port 202 define the first flow channel 21, that is, the first connecting port 201 and the second connecting port 202 connect the first flow channel 21, and the third connecting port 203 and the fourth connecting port 204 define the second flow channel 22, that is, the third connecting port 203 and the fourth connecting port 204 connect the second flow channel 22. The first flow channel 21 includes a first sub-segment 01, and the second flow channel 22 includes a second sub-segment 02. Along the height direction H of the thermal management assembly, the first sub-segment 01 is located above the line connecting the first connecting port 201 and the second connecting port 202, and the second sub-segment 02 is located above the line connecting the third connecting port 203 and the fourth connecting port 204. The height direction is defined as the vertically upward direction (opposite to the direction of gravity) after the flow channel component is installed in the vehicle. Reference Figure 1 and Figure 2 and Figure 3 The housing 11 has a receiving cavity 40, and the core 12 is at least partially located in the receiving cavity 40. The core 12 enables the first sub-segment 01 and the second sub-segment 02 to communicate with or not communicate with the outside through the receiving cavity 40.

[0022] In this embodiment, the flow channel component 2 is vertically installed on the vehicle. The first flow channel 21 and the second flow channel 22 are shaped like an inverted U. When filling at normal pressure, air will remain at the high point of the inverted U, and the two flow channels need to be vented. The housing can realize the venting of the two flow channels. Compared with setting venting functional components on the two flow channels respectively, the structure is more compact and occupies less space, thus making the structure of the thermal management component more compact.

[0023] When filling at atmospheric pressure, purging the gas from the flow channel components may cause some coolant to be discharged. To prevent the discharged coolant from affecting the entire integrated component, refer to... Figure 2 and Figure 3 In one embodiment of this application, the housing 11 has an exhaust channel 130, which connects the receiving cavity 40 to the outside. The core 12 can connect or not connect the first sub-segment 01 and the second sub-segment 02 with the exhaust channel 130. In another embodiment, the housing 11 may not have a separate exhaust channel 130. The first sub-segment 01 and the second sub-segment 02 exhaust gas through the receiving cavity 40. Specifically, by controlling the core 12 in the receiving cavity 40, the receiving cavity 40 is connected to the first sub-segment 01 or the second sub-segment 02, and the gas is discharged to the outside through the receiving cavity 40.

[0024] refer to Figure 3 In this embodiment, a receiving cavity 40 and a core 12 are used to exhaust the first sub-segment 01 and the second sub-segment 02. Specifically, the core has a third channel 330, which is connected to the outside. The housing 11 has a first channel opening 410 and a second channel opening 420. The core 12 can rotate relative to the housing to open or close the first channel opening 410 and the third channel 330. The core can also rotate relative to the housing to open or close the second channel opening 420 and the third channel 330, thereby exhausting the first sub-segment 01 and the second sub-segment 02 respectively.

[0025] The above-mentioned method of using a cavity 40 and a core 12 to control the flow of the first and second channels requires machining a third channel 330 on the core 12, which is complex. Therefore, to facilitate machining and reduce costs, it is possible to use multiple cavities and multiple cores to separately control the exhaust of the first and second sub-segments. Specifically, refer to... Figures 1-8 In this embodiment, the receiving cavity 40 includes a first cavity 41 and a second cavity 42, and the core 12 includes a first core 121 and a second core 122. The first core 121 is at least partially located in the first cavity 41, and the second core 122 is at least partially located in the second cavity 42. The first core 121 can connect or disconnect the first sub-segment 01 and the exhaust channel 130, and the second core 122 can connect or disconnect the second sub-segment 02 and the exhaust channel 130.

[0026] To further facilitate exhaust and save costs, a single exhaust channel can be used to achieve exhaust for multiple flow channel segments, see reference. Figure 2 In this embodiment, the wall forming the first cavity 41 has an exhaust port 400, which is connected to the exhaust channel 130. The housing 11 includes a connecting channel 43, one end of which is connected to the first cavity 41, and the other end of which is connected to the second cavity 42.

[0027] Furthermore, since the first core 121 and the second core 122 are only used to connect or close the flow channel with the external space, the electric control or rotational precision of the cores can be ignored. Considering processing and material costs, the first core 121 and the second core 122 use plastic plungers and are not electrically controlled; they are manually controlled by the operator. Specifically, refer to... Figure 5 and Figure 6 The walls forming the first cavity 41 and the second cavity 42 each include a bottom wall portion 411 and a peripheral wall portion 412. The bottom wall portion 411 of the first cavity 41 has a first channel opening 410 communicating with the first sub-segment 01, and the bottom wall portion 411 of the second cavity 42 has a second channel opening 420 communicating with the second sub-segment 02. The thermal management assembly includes a first seal 51, with two first seals 51 arranged circumferentially along the first channel opening 410 and the second channel opening 420, respectively. The first core 121 and the second core 122 each have an end wall portion 1211 and a side wall portion 1212. One side of the first seal 51 abuts against the bottom wall portion 411, and the other side of the first seal 51 abuts against the end wall portion 1211. The side wall portion 1212 is threadedly connected to the peripheral wall portion 412. In some embodiments, reference is made to... Figure 9 The side wall of the core is threaded with 1212, and part of the thread is cut to facilitate the discharge of gas through the thread. The thread can also prevent the gas from carrying a large amount of coolant and spraying out.

[0028] Further, the bottom wall portion 411 forming the first cavity 41 is defined as the first bottom wall portion 4111, the peripheral wall portion 412 forming the first cavity 41 is defined as the first peripheral wall portion 4123, the end wall portion 1211 located in the first core 121 is defined as the first end wall portion 1215, and the side wall portion 1212 located in the first core 121 is defined as the first side wall portion 1217. The first bottom wall portion 4111 is opposite to the first end wall portion 1215, and there is a threaded gap between the first side wall portion 1217 and the first peripheral wall portion 4123. The first bottom wall portion 4111 has a first channel opening 410, and the first channel opening 410 is connected to the first sub-segment 01 through the first channel 310. The first core 121 can rotate relative to the housing 11 and move towards or away from the first bottom wall portion 4111 to close or open the first channel opening 410.

[0029] The bottom wall portion 411 forming the second cavity 42 is defined as the second bottom wall portion 4112, the peripheral wall portion 412 forming the second cavity 42 is defined as the second peripheral wall portion 4124, the end wall portion 1211 located in the second core 122 is defined as the second end wall portion 1216, and the side wall portion 1212 located in the second core is defined as the second side wall portion 1218. The second bottom wall portion 4112 is opposite to the second end wall portion 1216, and there is a threaded gap between the second side wall portion 1218 and the second peripheral wall portion 4124. The bottom wall portion has a second channel opening 420, which communicates with the second channel 320. The second core 122 can rotate relative to the housing 11 and move towards or away from the second bottom wall portion 4112 to close or open the second channel opening 420.

[0030] The thermal management assembly includes two first seals 51, one of which abuts against a first bottom wall portion 4111 on one side and against a first end wall portion 1215 on the other side, and the other first seal 51 abuts against a second bottom wall portion 4112 on one side and against a second end wall portion 1216 on the other side.

[0031] The sidewall portion 1212 includes an external threaded section 1213 and a mounting section 1214, and the peripheral wall portion 412 includes an internal threaded section 4121 and a sealing section 4122. The internal threaded section 4121 is threadedly connected to the external threaded section 1213. The thermal management assembly includes a second seal 53, which abuts against the sealing section 4122 and the mounting section 1214 respectively.

[0032] The side wall of the first cavity has an exhaust port 400 and a first opening 431. The exhaust port 400 is connected to an exhaust channel. The side wall of the second cavity has a second opening 432. The connecting channel 43 connects the first opening 431 and the second opening 432. The exhaust port 400 and the first opening 431 are close to the first bottom wall 4111 relative to the sealing section 4122. The second opening 432 is close to the second bottom wall 4112 relative to the sealing section 4122.

[0033] In some embodiments of this application, in order to facilitate communication between both the first segment 01 and the second segment 02 and the receiving cavity 40, and to ensure that the structural size used for communication is small and easy to connect, refer to Figure 4 and Figure 5The receiving cavity 40 includes a first cavity 41 and a second cavity 42. The thermal management assembly includes a first connecting part 14 and a second connecting part 15. The first connecting part 14 has a first channel 310, one end of which is connected to a first sub-segment 01, and the other end of which is connected to the first cavity 41. The second connecting part 15 has a second channel 320, one end of which is connected to a second sub-segment 02, and the other end of which is connected to the second cavity 42. The second connecting part 15 includes a flexible tube 153, one end of which is fixedly disposed with the flow channel component 2, and the other end of which is fixedly disposed with the housing 11. The flexible tube 153 connects one of the flow channel segments and one of the receiving cavities. On the one hand, because of the flexibility of the flexible tube 153, the physical structure of the area between the flow channel segment and the receiving cavity is not restricted. On the other hand, the flexible tube 153 has a small size, which is beneficial to improving the compactness of the thermal management assembly.

[0034] Further, refer to Figure 4 and Figure 5 In order to facilitate the processing and forming of the shell and the flow channel components, the shell and the flow channel components are processed and formed separately and then fixedly connected. Thus, the first connecting part 14 includes an external part 23 and a connecting part 141. The external part 23 and the connecting part 141 are separate structures, the external part 23 and the flow channel component 1 are integral structures, the connecting part 141 and the shell 11 are integral structures, and the external part 23 and the connecting part 141 are fixedly connected.

[0035] Furthermore, in order to reduce processing costs and considering the convenience of the connection method, it is preferable that the outer part 23 protrudes from the shell 11 relative to the wall forming the first sub-segment 01. The structure of the outer part 23 is similar to that of the conventional flow channel plate quick-connect outer pipe structure. The outer part 23 is injection molded together with the flow channel plate. The molding method refers to the molding method of the conventional flow channel plate and quick-connect outer pipe. The pipe part 141 has a connecting cavity 140. The outer part 23 is at least partially located in the connecting cavity 140. The outer part 23 and the pipe part 141 are snapped together and fixed. Specifically, the outer part 23 and the pipe part 141 are snapped together and fixed by the snap-fit ​​member 6. The thermal management component has a third seal 55. The third seal 55 is arranged circumferentially along the axis of the outer part 23. The inner side of the third seal 55 abuts against the outer peripheral wall of the outer part 23, and the outer side of the third seal 55 abuts against the peripheral side wall of the connecting cavity 140.

[0036] refer to Figures 4-7 The second connection part includes a flexible pipe assembly, which includes a first connector 151, a second connector 152, and a flexible tube 153. The first connector 151 and the second connector 152 are located at the two ends of the flexible tube 153, respectively. The first connector 151 is threadedly connected to the housing 11, and the interface of the first connector 151 is connected to the second cavity 42. The second connector 152 is threadedly connected to the flow channel component, and the interface of the second connector 152 is connected to the second sub-segment 02 of the second flow channel 22.

[0037] To ensure smooth gas discharge in the first and second sub-segments, in some embodiments of this application, the wall forming the first sub-segment 01 has a first opening 210 that connects to the receiving cavity 40, and the wall forming the second sub-segment 02 has a second opening 220 that connects to the receiving cavity 40. Along the height direction H of the thermal management assembly, the first opening 210 is higher than or flush with the first sub-segment 01, and the second opening 220 is higher than or flush with the second sub-segment 02. "The first opening 210 is higher than or flush with the first sub-segment 01" means that a portion of the first sub-segment 01 is flush with the first opening 210, and the remaining portion of the first sub-segment 01 is lower than the first opening 210, or the first opening 210 is located on the top wall 212 of the first flow channel forming the first sub-segment 01, and the first opening 210 is higher than the entire first sub-segment 01. "The second opening 220 is higher than or flush with the second sub-segment 02" is similar and will not be described again here. Since the density of gas is less than that of coolant, gas generally accumulates in the high regions of the first flow channel 21 and the second flow channel 22, that is, in the high regions of the first sub-segment 01 and the second sub-segment 02. Placing the first opening 210 and the second opening 220 in the high regions is beneficial for the discharge of gas in the flow channels and thus for complete removal.

[0038] Furthermore, since the flow channel component is vertically mounted on the vehicle in this embodiment, that is, the extension plane of the flow channel component is perpendicular to or tends to be perpendicular to the horizontal plane, in order to facilitate the arrangement of the housing 11 and the flow channel, the wall forming the first sub-segment 01 includes the first flow channel side wall 211 and the first flow channel top wall 212, the first opening 210 is located on the first flow channel side wall 211, and along the height direction H of the thermal management component, the wall partially forming the first opening 210 is flush with the first flow channel top wall 212;

[0039] The wall forming the second sub-segment 02 includes a second flow channel sidewall 221 and a second flow channel top wall 222. The second opening 220 is located on the second flow channel sidewall 221. Along the height direction H of the thermal management assembly, the wall that partially forms the second opening 220 is flush with the second flow channel top wall 222.

[0040] The housing 11 includes a cavity 111 and an exhaust pipe 13. The exhaust pipe 13 is integrally formed with the cavity 111 and extends from the cavity 111 along the height direction H of the thermal management assembly. The exhaust pipe 13 has an exhaust port 1301, which is positioned higher than the first sub-segment 01 and the second sub-segment 02 along the height direction H of the thermal management assembly. Arranging the exhaust port 1301 of the exhaust pipe 13 at a high position facilitates guiding the gas to move upwards and helps to vent the gas in the first sub-segment 01, the second sub-segment 02, and the receiving cavity 40.

[0041] In the above embodiment, during atmospheric pressure filling, the other end of the vent pipe 13 is connected to the kettle spout via a hose and is open to the atmosphere. Coolant is added from the kettle, and the water pump in the thermal management circuit where the first flow channel 21 is located is operated to vent the gas in the first sub-section 01. That is, the first core 121 is loosened, and the coolant and gas in the first sub-section 01 move towards the first cavity 41 under the pressure of the water pump, and enter the venting channel through the threaded wall of the first core 121 and the threaded wall of the first cavity 41, thereby venting the gas and coolant to the kettle. After the system stabilizes (the coolant in the kettle is wavy), the system continues to operate. (If the flow is stable), tighten the first core 121 to complete the venting in the first sub-section 01; then control the water pump in the thermal management circuit where the second flow channel 22 is located to loosen the second core 122. The coolant and gas in the second sub-section 02 move to the second cavity 42 under the pressure of the water pump, and enter the connecting channel 43 through the threaded wall of the second core 122 and the threaded wall of the second cavity 42. Then, they enter the venting channel through the first cavity 41 and are discharged to the kettle. After the system is stable (the coolant in the kettle fluctuates smoothly), tighten the second core 122 to complete the venting in the second sub-section 02.

[0042] 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. For example, the directional definitions such as "front", "back", "left", "right", "up", and "down" are used. Although the present invention has been described with reference to the above embodiments, those skilled in the art should understand that they can still modify, combine or make equivalent substitutions to the present invention. All technical solutions and improvements that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
