[0035] In this embodiment, the shell 21 has a first heat exchange chamber 2111 and a second heat exchange chamber 2121. The heat exchange medium enters the first heat exchange chamber 2111 from the circulation inlet 2112, and flows through the first heat exchange chamber 2111, the connecting flow channel, the second heat exchange chamber 2121 in sequence to be discharged from the circulation outlet 2122. The heating element 22 is placed between the first heat exchange chamber 2111 and the second heat exchange chamber 2121, so that the opposite sides of the heating element 22 can heat the first heat exchange chamber 2111 and the second heat exchange chamber 2121 at the same time, further increasing the effective heat exchange area of ​​the heating element 22. The heat exchange medium fully absorbs and carries the heat released by the heating element 22 during the flow process, thereby being able to further give full play to the heating effect of the heating element 22.

[0036] In addition, placing the heating element 22 between the first heat exchange chamber 2111 and the second heat exchange chamber 2121, and filling the first heat exchange chamber 2111 and the second heat exchange chamber 2121 with heat exchange medium can adaptively balance the pressure on both sides of the heating element 22, thereby preventing deformation of the heating element 22 and surrounding components caused by excessive pressure on one side of the first heat exchange chamber 2111 or the second heat exchange chamber 2121.

[0037] In this embodiment, the heat exchange medium in this embodiment can be set to water.

[0038] In this embodiment, the controller 3 may be configured as an IPM control unit or an IGBT control unit.

[0039] Specifically, when the heating element 22 needs to be heated, the vehicle control unit transmits a signal to the controller 3, and the controller 3 controls the heating element 22 to heat. The low-temperature heat exchange medium flows through the first heat exchange cavity 2111 and the second heat exchange cavity 2121 in sequence from the circulation inlet 2112, and the heating element 22 generates heat to heat the heat exchange medium. The heat exchange medium after absorbing the heat flows out from the circulation outlet 2122 and is passed into the vehicle's heating system. After heat exchange in the heating system, it returns to the circulation inlet 2112, forming a complete cycle to achieve the heating function.

The heating element 22 is sandwiched between the first partition 213 and the second partition 214. Specifically, the arrangement of the first partition 213 and the second partition 214 can form a first heat exchange cavity 2111 and a second heat exchange cavity 2121 that are independent of each other in the shell 21, and the first partition 213 and the second partition 214 can jointly clamp and fix the heating element 22 disposed between the first heat exchange cavity 2111 and the second heat exchange cavity 2121, and the structure is stable and reliable.

[0044] Specifically, a first sealing ring 23 is provided between the first supporting platform 2113 and the first partition plate 213, and between the second supporting platform 2123 and the second partition plate 214. Specifically, the provision of the first sealing ring 23 can effectively block the gap between the first supporting platform 2113 and the first partition plate 213, and between the second supporting platform 2123 and the second partition plate 214, and prevent the leakage of heat exchange medium between the first supporting platform 2113 and the first partition plate 213, and between the second supporting platform 2123 and the second partition plate 214.

[0045] Optionally, the material of the first sealing ring 23 is set to rubber.

Specifically, when the first sub-shell portion 211 is covered on the second sub-shell portion 212, the end surface of the first branch channel 215 facing the second branch channel 216 and the end surface of the second branch channel 216 facing the first branch channel 215 are in a position facing the connecting position and fit each other. The first branch channel 215 and the second branch channel 216 jointly form a connecting channel, and the heat exchange medium in the first heat exchange chamber 2111 enters the second heat exchange chamber 2121 through the first branch channel 215 and the second branch channel 216 in sequence.

[0047] In this embodiment, a second sealing ring 24 is provided between the first branch channel 215 and the second branch channel 216.

By providing the second sealing ring 24, the gap at the junction of the first branch channel 215 and the second branch channel 216 can be effectively blocked to prevent leakage of heat exchange medium at the junction of the first branch channel 215 and the second branch channel 216.

[0048] Optionally, the material of the second sealing ring 24 is set to rubber.

[0049] Further, the first shell part 211 is provided with a plurality of first guide plates 217 at intervals on two first cavity walls opposite to the first heat exchange cavity 2111, and the plurality of first guide plates 217 on the two first cavity walls are alternately interspersed, and the first heat exchange cavity 2111 and the plurality of first guide plates 217 together form a first heat exchange channel with an S-shaped bend, and the circulation inlet 2112 is connected to the first end of the first heat exchange channel, and the connecting channel is connected to the second end of the first heat exchange channel.

[0051] In this embodiment, the first guide plate 217 is integrally formed with the first split shell portion 211, and the second guide plate 218 is integrally formed with the second split shell portion 212. This configuration can omit the connecting components for separate assembly between the first guide plate 217 and the first split shell portion 211 and the second guide plate 218 and the second split shell portion 212, and saves production and assembly time.
