[0015] In the above structure, a water cooling mechanism 5 is provided in the cooling box 3, and a cooling water pump 62 is provided near the lower end of the frame 6. The cooling water pump 62 draws water into the cooling box 3 through the water intake pipe 61, and then transports water to the water guide interface of the water cooling mechanism 5, and then transports it to the fixture 4 by the water cooling mechanism 5, so as to cool the IGBT devices on the fixture 4. Among them, the cooling box 3, the water intake pipe 61, the cooling water pump 62 and the water cooling mechanism 5 form a cooling water circulation waterway, which can not only quickly discharge the cooling water in the fixture 4, thereby realizing rapid water return, but also simplify the cooling water circulation waterway, thereby better meeting application requirements.
