[0034] In this embodiment, the controller 3 can control the compressor 1 to operate for cooling, and can also control the heating element 22 to heat the heat exchange cavity.

[0035] In this embodiment, the compressor 1 and the housing 21 are respectively fixed on opposite sides of the controller 3. The compressor 1 and the heating component 2 are separated by the controller 3, which can effectively avoid the mutual influence between the compressor 1 and the heating component 2, thereby avoiding the mutual influence between cooling and heating. In addition, a plurality of guide plates 2111 are arranged at intervals on the opposite side walls of the heat exchange cavity in the housing 21, and the guide plates 2111 on the two cavity walls are arranged alternately and interspersed. The heat exchange cavity and the plurality of guide plates 2111 together form a heat exchange channel 2112 arranged in an S-shaped bend. The external heat exchange medium can enter the first end of the heat exchange channel 2112 through the inlet 213, and flow out through the outlet 214 after flowing through the heat exchange channel 2112, so as to circulate. The setting of the heat exchange channel 2112 can effectively extend the flow path of the heat exchange medium, so that the heat exchange medium can fully exchange heat in the heat exchange cavity to ensure the heating effect.

[0036] In this embodiment, the heat exchange medium is set as a fluid medium. Preferably, the heat exchange medium is set as water.

[0037] In this embodiment, the controller 3 may be configured as an IPM control unit or an IGBT control unit.

[0038] 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 into the first end of the heat exchange channel 2112 from the inlet 213, and the heating element 22 generates heat to heat the heat exchange medium in the heat exchange channel 2112. After absorbing the heat, the heat exchange medium flows out from the second end of the heat exchange channel 2112 through the outlet 214 and is passed into the vehicle's heating system. After heat exchange in the heating system, it returns to the inlet 213, forming a complete cycle to achieve the heating function.

[0039] In this embodiment, the controller 3 can control the operation of the compressor 1 alone to realize the refrigeration cycle; can control the operation of the heating element 22 alone to realize the heating function; or can control the operation of the compressor 1 and the heating element 22 at the same time to perform heating and refrigeration cycles at the same time.

[0040] Optionally, the inlet 213 can be located at the bottom end of the side of the shell 21, and the outlet 214 can be located at the top end of the side of the shell 21. The heat exchange medium enters the heat exchange channel 2112 from the bottom end of the shell 21 and flows from the bottom end of the shell 21 to the top end of the shell 21, which can increase the heat exchange amount between the heat exchange medium and the heating element 22 and heat the heat exchange medium more efficiently.

[0041] Optionally, the inlet 213 can be located at the top end of the side of the shell 21, and the outlet 214 can be located at the bottom end of the side of the shell 21. The heat exchange medium enters the heat exchange channel 2112 from the top end of the shell 21 and flows from the top end of the shell 21 to the bottom end of the shell 21. The heat exchange amount between the heat exchange medium and the heating element 22 can also be increased, and the heat exchange medium can be heated more efficiently.

[0042] Furthermore, the housing 21 has a main cavity, and a heat exchange baffle 23 is provided in the main cavity. The heat exchange baffle 23 divides the main cavity into a receiving cavity and a heat exchange cavity, and the heating element 22 is provided in the receiving cavity. By providing the heat exchange baffle 23, a separate receiving cavity is formed, which is independent of the heat exchange cavity and is used to reliably place the heating element 22. The heat generated by the heating element 22 is transferred to the heat exchange flow channel 2112 through the heat exchange baffle 23, and the heat exchange medium in the heat exchange flow channel 2112 is heated.

The housing 21 is configured as an openable structure of the housing body 211 and the housing cover 212, so that the heat exchange cavity can be cleaned regularly. By providing the support boss 2113, the heat exchange baffle 23 can be reliably supported.

[0044] Furthermore, a sealing ring 215 is provided between the shell body 211 and the heat exchange baffle 23. The provision of the sealing ring 215 can effectively block the gap between the shell body 211 and the heat exchange baffle 23, prevent the leakage of the heat exchange medium, and ensure reliable sealing.

[0045] Furthermore, the heating component 2 also includes a connecting member 24, the shell cover 212 has a first connecting hole 2121, the heating element 22 has a second connecting hole 2211, the heat exchange baffle 23 has a third connecting hole 231, and the guide plate 2111 has a fourth connecting hole 21111.

[0046] In this embodiment, the first connection hole 2121 , the second connection hole 2211 , the third connection hole 231 , and the fourth connection hole 21111 are disposed in a one-to-one correspondence.

[0047] By providing the connecting piece 24, the shell body 211 and the shell cover 212 can be reliably fixed after the shell body 211 and the shell cover 212 are covered. The fourth connecting hole 21111 is provided on the guide plate 2111, which can make fuller use of the space of the guide plate 2111 to open holes, avoid opening holes at other positions of the shell body 211 to occupy the area of ​​the heat exchange flow channel 2112, make the structural layout reasonable, and do not affect the flow path of the heat exchange medium. In addition, opening the fourth connecting hole 21111 on the guide plate 2111 can also balance the force and reduce the deformation effect of the larger pressure in the heat exchange flow channel 2112 on the shell cover 212 and the heat exchange baffle 23.

[0048] Optionally, the connecting member 24 is a bolt, and the fourth connecting hole 21111 is correspondingly a threaded hole. Specifically, the bolt passes through the first connecting hole 2121, the second connecting hole 2211, the third connecting hole 231 and the fourth connecting hole 21111 and is threadedly connected, which has a simple structure and is easy to install.

[0049] In this embodiment, the guide plate 2111 is integrally formed with the shell body 211. This configuration can omit the connecting components for separate assembly between the guide plate 2111 and the shell body 211, and save production and assembly time.
