[0036] Since the waterway structures of the power module and the control module are separately arranged, independent cavities are formed between the power module and the control module, and the EMC performance between the power module and the control module can be further improved.
[0037] In some possible embodiments, referring to Figure 3 , the two ports of the IGBT waterway and the first group of cooling ports of the integrated shell 9 are both provided with the first sealing ring; and the two ports of the power supply waterway and the second group of cooling ports of the integrated shell 9 are both provided with the second sealing ring.
[0038] The control module and the power module where the IGBT waterway and the power supply waterway are located are fixedly connected with the integrated shell 9 through bolts, and the inlets and outlets of the two waterway structures are respectively connected with the cooling ports on the integrated shell 9, the inlets and outlets of the waterway structure and the corresponding cooling ports are sealed through the sealing ring, and a complete heat dissipation structure is formed.
[0039] Specifically, the sealing ring groove is arranged on the two groups of cooling ports of the integrated shell 9, and the sealing ring is installed in the sealing ring groove. When the control module and the power module are installed on the integrated shell 9 through the bolts, the module extrudes the sealing ring to be limited in the sealing ring groove, and is used for sealing the connection of the cooling port.
[0040] The sealing ring can be an O-ring.
[0041] In some possible embodiments, referring to Figure 1 and Figure 5 , the controller further comprises an IGBT module 11 and a DC-Link capacitor 13, and the IGBT module 11 and the DC-Link capacitor 13 are respectively located on the upper side and the lower side of the IGBT waterway.
[0042] The IGBT module 11 is bolted and installed on the body of the control module and located at the upper end of the IGBT waterway, and the DC-Link capacitor 13 is bolted and installed on the body of the control module and located at the lower end of the IGBT waterway. When the cooling water flows through the IGBT waterway, the cooling water can simultaneously cool the upper side and the lower side, that is, simultaneously dissipate heat of the IGBT and the DC-Link capacitor 13.
[0043] IGBT module 11 is a modular semiconductor product packaged by specific circuit bridging of IGBT (Insulated Gate Bipolar Transistor chip) and FWD (diode chip); the packaged IGBT module 11 is directly applied to frequency converters, UPS uninterruptible power supplies and other equipment.
[0044] DC-Link capacitor, also known as DC-Link capacitor, is a kind of passive device. DC-Link capacitor is referred to as capacitor 13 hereinafter.

The first liquid inlet port 5 and the first liquid outlet port 6 of the integrated shell 9 are used to communicate with the cooling water system.
[0049] The main cooling section 12 forms a rectangular water tank structure, which expands the flow area and slows down the flow rate of the cooling water, thereby improving the cooling effect of the cooling water when flowing through the main cooling section 12. Therefore, the IGBT module 11 and the capacitor 13 with high heat dissipation requirements are respectively installed on the upper and lower sides of the main cooling section 12, i.e. the IGBT module 11 is installed on the upper end of the main cooling section 12, and the capacitor 13 is installed on the lower end of the main cooling section 12.

The DC / DC converter is a voltage converter that converts the input voltage to a fixed output voltage. Both of them are installed on the control panel 15 as the main heat dissipation components.
[0053] The cooling water of the power water channel cools the OBC and the DCDC converter on the control panel 15 during the flow. In addition, signal wire harness, AC shield cover, AC filter board assembly 16, aluminum base plate, LVDV filter module and other devices are also fixed on the upper side and side of the power water channel.

[0062] Taking the cooling water flowing from the IGBT water channel to the power supply water channel as an example, the cooling water enters the liquid inlet section of the IGBT water channel from the first liquid inlet port 5 of the first group of cooling ports of the integrated shell 9, then sequentially passes through the liquid inlet section, the main cooling section 12 and the connecting section of the IGBT water channel, and cools the IGBT module 11 and the capacitor 13, and finally is discharged from the connecting section of the IGBT water channel to the first liquid outlet port 6 of the integrated shell 9.
