Wherein: the water cooling system 5 is located in the sealing area 3, the water cooling system 5 comprises a radiator and a cooling liquid circulation pipeline, the radiator is exposed out of the surface of the cabinet body 1, the radiator is connected in the cooling liquid circulation pipeline, and the cooling liquid circulation pipeline is suitable for extending to each power module.
Specifically, the cooling liquid circulation pipeline comprises a water inlet main pipeline, a water outlet main pipeline and a branch pipeline. Preferably, the main pipeline is made of stainless steel pipes, the branch pipelines are made of stainless steel corrugated pipes and rubber pipes, and the diameters of the branch pipelines are smaller than that of the main pipeline. Further, a temperature sensor and a pressure sensor may be provided at the main inlet pipe of the power module to detect the pressure and temperature of the pipe.
Specifically, the cooling liquid circulation pipeline is provided with an expansion tank, the expansion tank is connected with a water accumulation box, and the expansion tank is used for accommodating the expansion amount of system water and simultaneously has the functions of constant pressure and water replenishing for the system. It should be noted that, in this embodiment, the entire water cooling system 5 is disposed in the sealing area 3, i.e. the expansion tank is also disposed in the sealing area 3. Further, the expansion water tank is provided with a liquid level meter, and the expansion water tank, the liquid level meter and the radiator are integrally designed, so that a radiator filter screen can be cleaned without opening an AC cabinet door.
It is easy to understand that the radiator is exposed to the surface of the cabinet 1, i.e., the fins of the radiator are exposed to the outside, and can directly exchange heat with the outside air. Furthermore, in order to prevent external impurities from entering the radiator, the radiator is provided with a metal filter screen.
It will be readily appreciated that the radiator is connected to the coolant circulation line, i.e. the radiator is part of the coolant circulation line, with both the inlet and the outlet of the radiator being in communication with the coolant circulation line.
It is easy to understand that the cooling liquid circulation pipeline is suitable for extending to each power module, namely, according to the position of each power module, a plurality of branch pipelines are arranged on the cooling liquid circulation pipeline, and the plurality of branch pipelines extend to the power modules respectively so as to cool the power modules. Further, in order to improve the heat dissipation efficiency of the power module, a water cooling plate may be disposed on the branch pipe, and then the power module may be mounted on the water cooling plate.
Wherein: the air cooling system 6 comprises a centrifugal fan adapted to direct external air into the air duct section 2.
Specifically, the position of the centrifugal fan in the air duct area 2 is not limited, and may be top, middle or even bottom.

In addition, the converter cabinet is also provided with an open area 4, so that the product assembly, overhaul and maintenance are convenient.
In some embodiments, a centrifugal fan is mounted in the sealing area 3 and located inside the radiator, the centrifugal fan being adapted to introduce external wind into the radiator, and an air outlet of the centrifugal fan being introduced into the air duct area 2.
It will be readily appreciated that the centrifugal fan is located inside the radiator, i.e. the centrifugal fan is closer to the interior of the cabinet 1 than the radiator.
In the embodiments, the centrifugal fan is arranged on the inner side of the radiator, and the centrifugal fan sucks air, so that external air enters the radiator to radiate the cooling liquid of the water cooling system 5, and the cooling air enters the air channel region 2 after passing through the radiator to radiate the subsequent transformer and reactor. Therefore, on the basis of meeting the wind formation of the air duct area 2, the heat dissipation of the cooling liquid of the water cooling system 5 can be quickened, and the water cooling efficiency is improved. Although the radiator increases the temperature of the cooling air slightly, the effect of the radiator on the device in the duct area 2 is small and negligible.
On the basis, in some embodiments, the air duct area 2 is located in the front middle area of the cabinet body 1, the radiator is located at the left side top or the right side top of the cabinet body 1, the air outlet of the centrifugal fan is led to the top of the air duct area 2, and the air outlet of the air duct area 2 is located at the bottom end of the air duct area.

In some embodiments, a first partition 21 is disposed in the air channel region 2 to divide the air channel region 2 into multiple layers that are interconnected up and down.
It is easy to understand that the "intercommunication" is that the upper and lower layers are communicated, so that the air in the whole air channel region 2 can be blown to form cooling air under the action of the centrifugal fan.
Further, the first partition plate 21 can be set to be of a detachable structure, and a process port is reserved on the side face of the cabinet body 1, so that the assembly, the overhaul and the maintenance of devices in the air duct area 2 are facilitated.
These embodiments are more reasonable in spatial arrangement by layering the air duct section 2, and the transformers and reactors can be placed side by side and in layers in the air duct section 2.
In some embodiments, a second separator 31 is provided in the sealing region 3 to separate the sealing region 3 into multiple layers that are in up-down communication.
It is easy to understand that the "intercommunication" is that the upper and lower layers are communicated, so that the air in the whole sealing area 3 is communicated, and the phenomenon of uneven air temperature between different layers caused by non-circulation of the air is avoided.
By layering the sealing area 3, the power modules can be placed in the air duct area 2 side by side and in layers, and the space arrangement is more reasonable.
