The layout space has a great impact on the heater, and the layout of the heater is difficult and the layout method is not flexible enough.

[0061] The embodiment of the present application provides a thermal management component, including a delivery pipeline and a heater, the delivery pipeline includes a first pipeline section and a second pipeline section, the heater includes a water chamber and a heating element disposed in the water chamber, the opposite ends of the water chamber are respectively a water inlet end and a water outlet end, the water inlet end is detachably connected to the first pipeline section, and the water outlet pipe is detachably connected to the second pipeline section.

[0062] At the same time, since the heater is adapted to the pipeline and can be easily installed between pipeline sections, the installation method of the heater is relatively flexible. The heater can be selected and the installation position of the heater can be selected according to different heating requirements, which further improves the flexibility of the heater layout and the flexibility of the thermal management component, so that the thermal management component can flexibly adapt to different heating requirements.

[0063] The thermal management component disclosed in the embodiments of the present application can be used in vehicles. The vehicle can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc.

[0064] Please also refer to Figure 1 , Figures 3 to 6 The embodiment of the first aspect of the present application provides a thermal management component 100, including a delivery pipeline 10 and a heater 20. The delivery pipeline 10 is used to deliver coolant, and the delivery pipeline 10 includes a first pipeline section 11 and a second pipeline section 12 arranged in sequence, and the heater 20 is arranged in the delivery pipeline 10; the heater 20 includes a water chamber 21 and a heating element 22 arranged in the water chamber 21, the water chamber 21 is connected to the first pipeline section 11 and the second pipeline section 12, and the opposite ends of the water chamber 21 are respectively a water inlet end 201 and a water outlet end 202, the water inlet end 201 is detachably connected to the first pipeline section 11, and the water outlet end 202 is detachably connected to the second pipeline section 12.

[0065] The delivery pipeline 10 is used to deliver cooling liquid. In some embodiments, the cooling liquid is water. In other embodiments, the cooling liquid may also be other heat exchange media.

[0066] Please refer to Figure 1 The delivery pipeline 10 includes a first pipeline section 11 and a second pipeline section 12, which are arranged adjacent to each other, and the coolant can flow from the first pipeline section 11 to the second pipeline section 12; the first pipeline section 11 and the second pipeline section 12 can be pipe bodies, such as plastic pipes. The first pipeline section 11 and the second pipeline section 12 can be connected through a heater 20. It can be understood that the delivery pipeline 10 also includes other pipeline sections, so that the delivery pipeline 10 can form a coolant loop; in addition, the first pipeline section 11 and the second pipeline section 12 can be multiple groups, and a heater 20 is provided in one or more groups of pipeline sections.

[0067] The heater 20 is disposed in the delivery pipeline 10 and is used to heat the coolant in the delivery pipeline 10. The heater includes a water chamber 21 and a heating element 22 disposed in the water chamber 21. The water chamber 21 can contain the coolant and allow the coolant to circulate. The heating element 22 is disposed in the water chamber 21 and is used to heat the coolant in the water chamber 21. The heating element 22 can be a variety of heating elements, such as a PTC (Positive Temperature Coefficient) heating element, a ceramic electric heating tube, and the like.

[0068] Please refer to Figure 1 and Figure 3The two opposite ends of the water chamber 21 are respectively a water inlet end 201 and a water outlet end 202. The water inlet end 201 is detachably connected to the first pipe section 11, and the water outlet end 202 is detachably connected to the second pipe section 12, so that the water chamber 21 can be connected between the first pipe section 11 and the second pipe section 12, and the first pipe section 11, the heater 20 and the second pipe section 12 can form a passage for the circulation of the coolant. The water inlet end 201 and the first pipe section 11 can be detachably connected by socketing, threading, welding and the like, and the water outlet end 202 and the second pipe section 12 can also be detachably connected by socketing, threading, welding and the like.

[0069] During assembly, the heater 20 is placed between the first pipeline section 11 and the second pipeline section 12, the water inlet end 201 of the water chamber 21 is connected to the first pipeline section 11, and the water outlet end 202 of the water chamber 21 is connected to the second pipeline section 12, and the heater 20 can be connected to the delivery pipeline 10, and the water chamber 21 is connected to the first pipeline section 11 and the second pipeline section 12. When in use, the coolant flows from the first pipeline section 11 into the water chamber 21 and is heated by the heating element 22, and then the coolant flows from the water chamber 21 to the second pipeline section 12, and then flows to the components such as the battery that need to be heated, so that thermal management can be achieved.

[0070] like Figure 2 As shown, the first pipeline section 11 and the second pipeline section 12 can also be connected through a connecting pipe 13. The connecting pipe 13 can be a straight pipe and the connecting pipe 13 can be fixed on the beam body 200 of the vehicle, and the two ends of the connecting pipe 13 are detachably connected to the first pipeline section 11 and the second pipeline section 12 respectively. It can be seen that the heater 20 provided in the embodiment of the present application can be adapted to the conveying pipeline 10, and the heater 20 can directly replace the connecting pipe 13. The heater 20 can be flexibly arranged between two adjacent pipeline sections, so that the influence of the spatial position on the arrangement of the heater 20 is greatly reduced, and a more flexible arrangement is achieved.

[0071] The thermal management component 100 provided in the embodiment of the present application includes a delivery pipeline 10 and a heater 20. The delivery pipeline 10 includes a first pipeline section 11 and a second pipeline section 12. The heater 20 includes a water chamber 21 and a heating element 22 disposed in the water chamber 21. The water inlet end 201 of the water chamber 21 is detachably connected to the first pipeline section 11, and the water outlet end 202 of the water chamber 21 is detachably connected to the second pipeline section 12. In this way, the heater 20 can flow the coolant through the water chamber 21 and heat the coolant using the heating element 22. The heater 20 can be detachably connected between adjacent pipeline sections, that is, the heater 20 can be adapted to the delivery pipeline 10, so that the heater 20 can directly replace the connecting pipe 13 originally disposed between adjacent pipeline sections. The heater 20 provided in the embodiment of the present application is adapted to the delivery pipeline 10 and can be installed between adjacent pipeline sections, so that the influence of the spatial position on the arrangement of the heater 20 is greatly reduced, and a more flexible arrangement is achieved.

[0072] At the same time, since the heater 20 is adapted to the delivery pipeline 10, the installation method of the heater 20 is relatively flexible, and the heater 20 can be selected and the installation position of the heater 20 can be selected according to different heating requirements, which further improves the flexibility of the arrangement of the heater 20 and the flexibility of the thermal management component 100, so that the thermal management component 100 can flexibly adapt to different heating requirements. In some cases, the vehicle can have different heating requirements in different use areas, and different heating configurations can be implemented for the same model. For example, the same model can be equipped with a heater 20; in some cases, the same thermal management system can be equipped with multiple heaters 20 to integrate multi-point heating functions, expanding and enriching the functions of the thermal management system.

[0073] Please refer to Figure 1 , Figure 3 In some embodiments, the water inlet end 201 is socketed with the first pipeline section 11, and the water outlet end 202 is socketed with the second pipeline section 12; the thermal management component 100 also includes a clamping member 30, the clamping member 30 is clamped on the water inlet end 201 and the first pipeline section 11, and / or the clamping member 30 is clamped on the water outlet end 202 and the second pipeline section 12.

[0074] The water inlet end 201 and the water outlet end 202 are two opposite ends of the water chamber 21, which are used for water inlet and water outlet, respectively. The sizes of the water inlet end 201 and the water outlet end 202 can be adapted to the sizes of the first pipe section 11 and the second pipe section 12, so as to facilitate mutual connection. Optionally, the water inlet end 201 and the water outlet end 202 are both in the shape of a circular tube, and the cross-sectional dimensions of the water inlet end 201 and the water outlet end 202 are smaller than the cross-sectional dimensions of the rest of the water chamber 21.

[0075] In this embodiment, the first pipe section 11 is sleeved on the outside of the water inlet end 201, and the second pipe section 12 is sleeved on the outside of the water outlet end 202. In another embodiment, the water inlet end 201 can also be sleeved on the end of the first pipe section 11, or the water outlet end 202 can be sleeved on the end of the second pipe end.

[0076] Optionally, the clamping member 30 is clamped on the outside of the water inlet end 201 and the first pipe section 11, so that the water inlet end 201 is stably connected to the first pipe section 11; the clamping member 30 is clamped on the outside of the water outlet end 202 and the second pipe section 12, so that the water outlet end 202 is stably connected to the second pipe section 12. The clamping member 30 can be a cable tie, a clamp, etc.

[0077] By adopting the above technical solution, the water inlet end 201 and the water outlet end 202 of the water chamber 21 can be connected to the delivery pipeline 10 by sleeve connection, and the clamping member 30 can stably connect the water chamber 21 with the delivery pipeline 10, and the assembly method of the heater 20 and the delivery pipeline 10 is relatively simple and efficient. When the heater 20 needs to replace the original connecting pipe 13, there is no need to change the structure of the first pipeline section 11 and the second pipeline section 12. The heater 20 has good adaptability and a flexible and convenient installation method.

[0080] Optionally, the beam body 200 is provided with a beam body mounting hole 210.

[0081] By providing the fixing portion 23 on the outer peripheral wall of the heater 20 , the heater 20 can be conveniently fixed on the beam body 200 of the vehicle, so that the heater 20 can be stably installed on the vehicle.

[0082] In some embodiments, the fixing portion 23 is provided with a mounting hole, and the fastener 50 can be installed in the mounting hole to fix the heater 20 to the beam body 200. Specifically, the fastener 50 is simultaneously passed through the mounting hole of the fixing portion 23 and the beam body mounting hole 210, so that the heater 20 can be fixed to the beam body 200.

[0083] In this way, the heater 20 can conveniently replace the connecting pipe 13 , and the heater 20 can be directly adapted to the beam body 200 , so that the heater 20 can be stably installed.

[0084] In other embodiments, the fixing portion 23 may also be fixedly connected to the beam body 200 in other ways, for example, the fixing portion 23 is welded or clamped on the beam body 200 .

In some embodiments, the end cap 212 and the water chamber body 211 are detachably connected to facilitate the installation of the heating element 22. Optionally, a first connection hole 2122 is provided on the end cap, and a second connection hole is correspondingly provided on the water chamber body 211. The end cap 212 and the water chamber body 211 can be fixedly connected by fasteners penetrating the corresponding first connection hole 2122 and the second connection hole.

[0088] The water inlet 2011, the main channel 2111, and the water outlet 2021 are connected in sequence to form a heater channel. The water inlet 2011 is connected to the first pipeline section 11, and the water outlet 2021 is connected to the second pipeline section 12. The heating element 22 is arranged in the main channel 2111 and can heat the coolant in the main channel 2111.

[0089] By adopting the above technical solution, the water chamber 21 includes a water chamber body 211 and an end cover 212 connected to one end of the water chamber body 211, so as to facilitate the installation of the heating element 22 in the water chamber 21; the water inlet 2011, the main channel 2111 and the water outlet 2021 are connected in sequence, and when the coolant is transported in the delivery pipeline 10, the coolant flowing through the main channel 2111 can be directly heated by the heating element 22. The thermal management component 100 provided in the embodiment of the present application can set the heater 20 in the delivery pipeline 10, saving the space occupied by the heater 20, and the installation flexibility of the heater 20 is better.

[0090] The water chamber 21 may also have other structures. For example, the end cover 212 may be omitted, or end covers 212 may be provided at both ends of the water chamber 21 .

[0091] In some embodiments, the water inlet end 201 and the water outlet end 202 are disposed at opposite ends of the water chamber 21 along the first direction, and the main flow channel 2111 extends along the first direction.

[0092] The first direction is Figure 5 The first direction is the X direction in the water chamber 21. The main channel 2111 extends along the first direction, that is, the main channel 2111 is a straight channel. Further, the water inlet 2011, the main channel 2111 and the water outlet 2021 can be arranged in sequence along the first direction.

[0093] By adopting the above technical solution, the main channel 2111 in the water chamber 21 is a straight channel, and the heater 20 can replace the straight pipe section for the coolant to flow directly through. The coolant can flow smoothly through the main channel 2111 in the water chamber 21, and it is not easy to reduce the transmission speed of the coolant.

[0094] In other embodiments, the main flow channel 2111 may also include a plurality of bent sub-flow channels to increase the circulation time of the coolant in the heater 20 .

[0095] Please refer to Figure 4 and Figure 6 In some embodiments, the heating element 22 is a cylinder, and the heating element 22 divides the main channel 2111 into a first sub-channel 2111a and a second sub-channel 2111b. The first sub-channel 2111a is located inside the heating element 22, and the second sub-channel 2111b surrounds the outside of the heating element 22. The second sub-channel 2111b is connected to the first sub-channel 2111a. The heating element 22 can heat the coolant in the first sub-channel 2111a and the second sub-channel 2111b at the same time.

[0096] The heating element 22 is a cylinder, and optionally, the heating element 22 is a cylinder with two ends connected. The heating element 22 is arranged in the main channel 2111 and divides the main channel 2111 into a first sub-channel 2111a and a second sub-channel 2111b. The first sub-channel 2111a is located inside the heating element 22, and the second sub-channel 2111b surrounds the outside of the heating element 22, that is, the second sub-channel 2111b is an annular channel arranged between the outer wall of the heating element 22 and the inner wall of the water chamber body 211. The first sub-channel 2111a and the second sub-channel 2111b are connected, and the coolant can flow from the first sub-channel 2111a into the second sub-channel 2111b, and then into the water outlet 2021.

[0097] By adopting the above technical solution, the heating element 22 can heat the coolant in the first sub-channel 2111a and the second sub-channel 2111b at the same time, thereby effectively improving the heating efficiency.

[0098] It can be understood that in other embodiments, the shape of the heating element 22 can also be other shapes such as a flat plate. The heating element 22 does not separate the main channel 2111, so the heating element 22 can directly heat the coolant on its surrounding side.

[0099] Please continue to refer to Figure 6 In some embodiments, a sealing portion 2112 is provided on the side of the water chamber body 211 away from the water inlet end 201, and the sealing portion 2112 is connected to the end of the heating element 22 away from the water inlet end 201. The end of the heating element 22 close to the water inlet 2011 is sealed and connected to the inner wall of the end cover 212. A connecting space 2112a is provided inside the sealing portion 2112. The connecting space 2112a is connected to the first sub-channel 2111a and the second sub-channel 2111b at the same time. The first sub-channel 2111a is connected to the water inlet 2011, and the second sub-channel 2111b is connected to the water outlet 2021.

[0100] The plugging portion 2112 is disposed inside the water chamber body 211. The plugging portion 2112 may be formed integrally with the rest of the water chamber body 211, or may be fixedly connected inside the water chamber body 211. The plugging portion 2112 is connected to the end of the heating element 22, and a connecting space 2112a disposed toward the heating element 22 is formed inside the plugging portion 2112. At the same time, one end of the heating element 22 close to the water inlet 2011 is sealed and connected to the inner wall of the end cover 212, so that the coolant can enter the first sub-channel 2111a from the water inlet 2011, and then flow into the second sub-channel 2111b through the connecting space 2112a, and then flow from the second sub-channel 2111b to the water outlet 2021.

[0101] By adopting the above technical solution, the coolant can flow through the first sub-channel 2111a and the second sub-channel 2111b successively, and can be heated by the heating element 22 in the process of flowing through the first sub-channel 2111a and the second sub-channel 2111b. On the one hand, the heating efficiency of the heater 20 is relatively high. On the other hand, the heating element 22 is sealed and connected to the end cover 212, and the sealing of the heater 20 is relatively good.

[0102] Please refer to Figure 3 and Figure 6 In some embodiments, a wire hole 2121 is provided on the end cover 212 , and the wire hole 2121 is used to pass the wire harness of the heating element 22 .

[0103] The wiring harness of the heating element 22 can be a power line, a signal line, etc. of the heating element 22. By providing a wire hole 2121 on the end cover 212, the wiring harness of the heating element 22 can pass through the wire hole 2121 to connect to components such as the power supply 40 and the control component to control the heating element 22.

[0104] Please refer to Figure 1 , Figure 3 and Figure 6 In some embodiments, the thermal management component 100 further includes a power supply 40 , which is disposed outside the water chamber 21 and connected to the heating element 22 via a wiring harness. The power supply 40 can be switched on and off to control the heating action of the heating element 22 .

[0105] The power supply 40 is used to supply power to the heating element 22. The heating action of the heating element 22 can be controlled by controlling the switch of the power supply 40. The heater 20 provided in the embodiment of the present application does not need to be provided with components such as a control circuit board and a controller. The operation of the heater 20 can be controlled by controlling the switch of the power supply 40 to adapt to different heating requirements. The control method of the heater 20 is relatively simple, and the cost of the heater 20 is relatively low.

[0106] It can be understood that in other embodiments, the heater 20 can also be controlled by components such as a controller.

[0107] Please refer to Figure 6 In some embodiments, the heating element 22 is disposed in both the water chamber body 211 and the end cover 212 , a first sealing member 26 is disposed between the end cover 212 and the heating element 22 , and a second sealing member 27 is disposed between the end of the water chamber body 211 close to the end cover 212 and the heating element 22 .

[0108] The first seal 26 and the second seal 27 can be sealing rings or other elastic seals. In this embodiment, one end of the heating element 22 is arranged in the end cover 212, and the first seal 26 is arranged between the inner wall of the end cover 212 and the outer wall of the heating element 22; the main body of the heating element 22 is arranged in the water chamber body 211, and the second seal 27 is arranged between the end of the heating element 22 close to the end cover 212 and the inner wall of the water chamber body 211. The first seal 26 can reduce the risk of leakage of the cooling liquid from between the heating element 22 and the end cover 212, and the second seal 27 can reduce the risk of leakage of the cooling liquid from between the heating element 22 and the water chamber body 211. Moreover, since the end cover 212 is fixedly connected to the water chamber body 211, the first seal 26 and the second seal 27 can also reduce the risk of leakage of the cooling liquid from the connection between the end cover 212 and the water chamber body 211. In this way, the above-mentioned heater 20 has good sealing performance.

[0109] In some embodiments, a flange 221 is provided on the peripheral side of the heating element 22 , the flange 221 abuts against the inner wall of the water chamber body 211 close to one end of the end cover 212 , and the second sealing member 27 is provided between the flange 221 and the water chamber body 211 .

[0110] The flange 221 may be a boss structure disposed around the heating element 22, and the flange 221 abuts against the water chamber body 211, so that the flange 221 can limit the heating element 22. The second sealing member 27 is disposed between the flange 221 and the water chamber body 211, and can seal the end of the second sub-channel 2111b away from the water outlet 2021.

[0111] A water inlet 2011 is provided inside the end cover 212 , and a receiving hole communicating with the water inlet 2011 is also provided inside the end cover 212 . It can be understood that the structure of the receiving hole is adapted to the heating element 22 .

[0112] Please refer to 4 and Figure 6 In some embodiments, the heating element 22 further includes a shell 24 and a heat insulating layer 25 . The shell 24 is sleeved on the outside of the water chamber 21 , and the heat insulating layer 25 is disposed between the shell 24 and the water chamber 21 .

[0113] Since the heating element 22 is arranged in the water chamber 21, the temperature of the water chamber 21 is relatively high, and the temperature of the outer surface of the heater 20 can be reduced by providing the heat insulation layer 25 and the shell 24, thereby reducing the impact of the heater 20 on the surrounding environment. The shell 24 can be made of plastic or metal, and the heat insulation layer 25 can be a heat insulation structure such as heat insulation foam, heat insulation fiber layer, etc.

[0114] The shell 24 can be cylindrical, square, or a special-shaped structure. As long as the outer contour of the shell 24 can fit the installation space, the heater 20 can achieve a richer and more flexible appearance structure design according to the layout requirements of different positions.

[0115] It can be understood that since the heater 20 is arranged between the pipeline sections, compared with the traditional heater, the heater 20 provided in the embodiment of the present application can be set to a smaller volume and occupy less space, which further improves the flexibility of the layout of the heater 20.

[0116] In some embodiments, the heating element 22 includes at least one of a ceramic electric heating tube, a PTC heating element, and a heating film.

[0117] Ceramic electric heating tubes are made of good ceramic as the base and high-quality electric heating wires. The working principle of PTC heating elements is based on the resistance-temperature characteristics of PTC materials. When current passes through the PTC material, heat is generated inside the material, causing the temperature to rise. Since the resistance of the PTC material increases with the increase in temperature, the current encounters greater resistance when flowing in the material, which reduces the heat generation and realizes automatic temperature control. There are many types of heating films, such as silicone heating films, polyimide heating films, PET heating films, etc.

[0118] By adopting the above technical solution, the heater 20 can flexibly select various types of heating elements 22, as long as the overall structural requirements and heating function requirements are met, so that the entire heater 20 can be more widely used.
