[0027] The purpose of this invention is to provide a water-cooled dual-power module that is small in size and can dissipate heat from the components installed inside.

[0028] To achieve the above objectives, the present invention provides the following technical solution:

[0029] Please see Figure 1 and Figure 2 This embodiment provides a water-cooled dual-power module, including: a housing assembly with an internal cavity, a capacitor assembly 01 installed on one side of the bottom of the cavity, a reactor 02 installed on the other side, a water-cooling plate 03 installed on the top of the reactor 02, a module assembly 04 installed on the top of the water-cooling plate 03, a stacked busbar 05 installed on the module assembly 04 to connect the capacitor assembly 01 and the module assembly 04, the module assembly 04 being electrically connected to the reactor 02, a control board assembly mounted inside the housing assembly, and an inlet copper busbar 06 connected to the stacked busbar 05 and an outlet copper busbar 07 connected to the reactor 02 installed on the same side wall of the housing assembly.

[0030] Specifically, such as Figure 1 As shown, in this embodiment, all internal components of the water-cooled dual-power module are installed in the housing assembly. The size and shape of the housing assembly can be adjusted according to actual conditions, and are not specifically limited herein. Inside the housing assembly, a capacitor assembly 01, a module assembly 04, a reactor 02, a stacked busbar 05, a control board assembly, an incoming copper busbar 06, and an outgoing copper busbar 07 are installed. Furthermore, to facilitate heat dissipation for these components, a water-cooling plate 03 is also provided inside the housing assembly. Firstly, the capacitor assembly 01 is installed on one side of the bottom of the housing assembly, and the reactor 02 is installed on the other side of the bottom of the housing assembly. Meanwhile, the reactor 02... A water-cooled plate 03 is installed on the top, and a module assembly 04 is installed on the upper side of the water-cooled plate 03. A stacked busbar 05 is installed on the module assembly 04, and the stacked busbar 05 is electrically connected to the top of the capacitor assembly 01. In addition, the inlet copper busbar 06 and the outlet copper busbar 07 are installed inside the housing cavity. The inlet copper busbar enters the stacked busbar 05 through a cable. The stacked busbar 05 can also input the transmitted electricity into the capacitor assembly 01. The module assembly 04 is also electrically connected to the reactor 02 through a cable, and the reactor 02 is electrically connected to the outlet copper busbar through a cable. The module assembly 04 is also electrically connected to the control board assembly through a cable.

[0031] It should be noted that all these components are installed around the water-cooled plate 03 for heat dissipation. In this embodiment, the water-cooled plate 03 has a channel for water flow. During use, cold water can be introduced into the water inlet of the water-cooled plate 03, and then the cold water flows inside the water-cooled plate 03. After absorbing heat, it will flow out from the water outlet of the water-cooled plate 03. In this embodiment, the water-cooled plate 03 is manufactured by vacuum soldering. This design can further reduce the volume of the entire power module and improve the heat dissipation effect.

[0032] The specific workflow of the power module in this embodiment is as follows: External power is supplied to the incoming copper busbar 06, passes through the laminated busbar 05, enters the capacitor assembly 01 for filtering, and then passes through the laminated busbar 05 again to the module assembly 04, where it is converted into AC power with variable voltage and frequency. The AC power is then output via cable to the reactor 02 for filtering, and the filtered AC power is re-output to the outgoing copper busbar 07. The control board assembly can control the voltage and frequency of the AC power converted by the module assembly 04. During the operation of the dual power module, the water-cooling plate 03 can cool the components inside the housing cavity. Furthermore, the internal component structure of the power module provided by this invention is compact, reducing its overall size.

[0033] Preferably, the housing assembly includes: a base plate 08, a front panel 09 and a rear panel 10 that are parallel to each other, a left side panel 11 and a right side panel 12 that are parallel to each other, and a top cover plate 13 that is parallel to the base plate 08. The base plate 08, the front panel 09, the rear panel 10, the left side panel 11, the right side panel 12 and the top cover plate 13 are connected by screws to form a receiving cavity, and the base plate 08, the front panel 09, the rear panel 10, the left side panel 11, the right side panel 12 and the top cover plate 13 can all be installed or removed independently.

[0034] In this embodiment, as Figure 1 and Figure 2 As shown, the housing assembly has a square structure, which is composed of six plates. The six plates are fixed together with screws. Specifically, the six plates are a bottom plate 08, a front panel 09, a rear panel 10, a left side panel 11, a right side panel 12, and a top cover 13. In this embodiment, the bottom plate 08 is used to support the other components. In this embodiment, each of the six plates can be disassembled or installed independently, which facilitates the maintenance of the internal components.

[0035] Preferably, the capacitor assembly 01 includes a capacitor 011 and a capacitor mounting plate 012. The capacitor mounting plate 012 is mounted on the base plate 08, and the length extension direction of the capacitor mounting plate 012 is parallel to the rear panel 10. The capacitor 011 can be inserted into the capacitor mounting plate 012.

[0036] like Figure 1 As shown, the capacitor assembly 01 in this embodiment mainly includes a cylindrical capacitor 011 and a capacitor mounting plate 012 for mounting the capacitor 011. The capacitor mounting plate 012 is fixedly mounted on the base plate 08 and is close to the water-cooling plate 03. The capacitor mounting plate 012 is provided with multiple mounting slots, and the overall length direction of the capacitor mounting plate 012 is parallel to the front panel 09 and the rear panel 10. With this configuration, it is very convenient to install or replace the capacitor 011.

[0037] Preferably, the water-cooled plate 03 is connected to the left side plate 11 and the right side plate 12 by screws, and the lower side of the water-cooled plate 03 abuts against the top of the reactor 02. The reactor 02 is mounted on the base plate 08 by screws.

[0038] In this embodiment, the water-cooled plate 03 is mounted inside the housing assembly. Specifically, its two sides are connected to the left side plate 11 and the right side plate 12 respectively by screws. It is not only parallel to the bottom plate 08, but its distance from the bottom plate 08 is also exactly the same as the height of the reactor 02. This arrangement allows the top of the reactor 02 installed on the bottom plate 08 to abut against the lower side of the water-cooled plate 03 for heat dissipation.

[0039] Preferably, the inner side of the rear panel 10 is provided with two incoming copper busbars 06 and six outgoing copper busbars 07, and the incoming copper busbars 06 and outgoing copper busbars 07 are arranged in a straight line. The rear panel 10 is provided with a first through hole 101 corresponding to the incoming copper busbars 06 and the six outgoing copper busbars 07.

[0040] In this embodiment, two incoming copper busbars 06 and six outgoing copper busbars 07 are arranged on the inner side of the rear panel 10. This arrangement allows the power module to simultaneously have multiple input and multiple output modes. Of course, the number of outputs can be adjusted according to actual needs. In this embodiment, the incoming copper busbars 06 and outgoing copper busbars 07 are arranged in a row on the rear panel 10, and the straight line they form is parallel to the base plate 08. In order to input DC power and output AC power, the rear panel 10 has a first through hole 101 at each position of the corresponding incoming copper busbar 06 and outgoing copper busbar 07 to expose them. In this embodiment, the two incoming copper busbars 06 are in the middle, and the six outgoing copper busbars 07 are evenly distributed on both sides of the two incoming copper busbars 06. This arrangement makes the overall appearance more aesthetically pleasing.

[0041] Furthermore, a high-voltage connector mounting plate 102 is provided on the outer side of the rear panel 10 corresponding to the first through hole 101. The high-voltage connector mounting plate 102 is used to install the high-voltage connector 103. The high-voltage connector 103 can be inserted into the incoming copper busbar 06 or the six outgoing copper busbars 07. The high-voltage connector mounting plate 102 is specifically made of insulating material.

[0042] In this embodiment, in order to make the use of the power module more convenient and quick, a high-voltage connector mounting plate 102 is provided on the outer side of the rear panel 10 corresponding to the first through hole 101. The high-voltage connector mounting plate 102 is integrally formed of insulating material. After its installation, the connection with the incoming copper busbar 06 and the outgoing copper busbar 07 can be directly achieved by plugging and unplugging the high-voltage connector 103. This setting greatly improves the convenience of the operator.

[0043] Preferably, a fan 104 is also provided on the inner side of the rear panel 10, and a ventilation opening is provided on the rear panel 10 corresponding to the position of the fan 104.

[0044] Understandably, in order to further improve the heat dissipation efficiency inside the power module, a fan 104 is also installed inside the housing assembly, and the fan 104 is installed on the inside of the rear panel 10. Ventilation holes are opened at the corresponding positions of the fan 104. This arrangement makes the heat dissipation effect inside the power module better.

[0045] Preferably, the front panel 09 is provided with a second through hole 091 corresponding to the water inlet and outlet of the water-cooled plate 03, and a high-sealing hot-pull water connector 092 is inserted into the second through hole 091.

[0046] like Figure 1 and Figure 2 As shown, in order to facilitate the introduction of cold water into the water-cooled plate 03 and the discharge of water that has absorbed heat, high-seal hot-swappable water connectors 092 are inserted into the water inlet and outlet of the water-cooled plate 03, and a second through hole 091 is provided at the corresponding position on the front panel 09. This arrangement allows the water-cooled plate 03 to be quickly installed each time the power module is used through the high-seal hot-swappable water connectors 092.

[0047] Preferably, both the water-cooled plate 03 and the housing assembly are made of aluminum alloy.

[0048] Understandably, the water-cooled plate 03 and the housing assembly need to bear a certain weight, and considering the processing cost, in this embodiment, the material of both is preferably aluminum alloy, which has a certain hardness and also has a good heat dissipation effect.

[0049] Of course, the materials of the water-cooled plate 03 and the shell components can also be adjusted according to the actual situation, such as choosing copper. This article does not make specific restrictions.

[0050] Preferably, both the upper and lower sides of the water-cooled plate 03 are coated with thermally conductive silicone grease.

[0051] Understandably, thermal grease not only has insulating properties but also good thermal conductivity. Therefore, it is applied to the top and bottom sides of the water-cooled plate 03 to prevent current from being conducted into the water-cooled plate 03 without affecting the thermal conductivity.

[0052] In summary, this embodiment provides a water-cooled dual-power module, which consists of a base plate 08, a rear panel 10, a right side panel 12, and a front panel 09 forming an open-top housing. The high-voltage connector mounting plate 102 is installed on the outside of the rear panel 10, and the inlet copper busbar 06, outlet copper busbar 07, and fan 104 are installed on the inside of the rear panel 10. The capacitor assembly 01 and reactor 02 are installed on the base plate 08. The water-cooling plate 03 and the control board mounting plate are then fixed between the right side panel 12 and the left side panel 11. The stacked busbar 05 is then installed on the module assembly 04, and the module assembly 04 is fixedly installed on the water-cooling plate 03. The high-seal hot-swappable water connector 092 is then installed on the outside of the front panel 09 assembly. Finally, the top cover plate 13 is placed on top to form the entire water-cooled dual-power module.
