[0055] The heat dissipation medium flows through the aluminum shell body 1 and the corresponding output row 2, and the heat can be directly transferred to the heat dissipation medium through the aluminum shell body 1. Compared with the existing method in which the heat is first transferred from the aluminum shell body 1 to the output row 2 and then transferred to the heat dissipation medium through the output row 2, the heat dissipation efficiency of this application is relatively fast.

[0056] The surfaces of the aluminum shell body 1 and the output row 2 are both provided with a plurality of mounting holes 3 , and the two output rows 2 are located on the same side where the two aluminum shell bodies 1 are connected as a whole.

The two aluminum shell bodies 1 are insulated and connected to form a complete aluminum shell body 1, which can prevent the two aluminum shell bodies 1 from conducting electricity and burning the rectifier module set on the aluminum shell body 1. The output row 2 is set on the aluminum shell body 1, which is an integrated design. The heat dissipation component is set on the aluminum shell body 1 and the corresponding output row 2, so that the heat on the aluminum shell body 1 can be directly dissipated through the heat dissipation component, or after passing through the output row 2, it can be dissipated by the heat dissipation component, thereby improving the heat dissipation efficiency.

[0063] The insulating plate 5 is located between the two aluminum shell bodies 1, and the two aluminum shell bodies 1 are respectively in contact with the insulating plate 5; wherein the insulating plate 5 does not protrude from the edges of the two aluminum shell bodies 1, so that there will be no interference between the insulating plate 5 and the transformer core in the accommodating cavity 4.

[0064] There are several connecting notches 6, which are arranged on one of the aluminum shell bodies 1, and the connecting notches 6 have a connecting plane close to the other aluminum shell body 1;

The connecting bolt is screwed with the connecting hole 7 on the other aluminum shell body 1. The part of the connecting bolt located in the insulating particle 8 can be screwed with the insulating particle 8. The insulating particle 8 and the connecting hole 7 are interference fit, so that the connecting bolt is connected to the aluminum shell body 1 through the insulating particle 8. The head of the connecting bolt can also abut against the head of the insulating particle 8. If one of the aluminum shell bodies 1 has a tendency to move away from the other aluminum shell body 1, the head of the connecting bolt and the head of the insulating particle 8 will limit one of the aluminum shell bodies 1.

[0068] The insulating plate 5 is arranged between the two aluminum shell bodies 1 to isolate the two aluminum shell bodies 1. The connection notch 6 can provide an operating space for installing the insulating particles 8 and the connecting bolts. The connecting bolts are sleeved on the inner side of the insulating particles 8 located on one of the aluminum shell bodies 1, and the insulating particles 8 can insulate the connecting bolts from the aluminum shell body 1. The connecting bolts connect the two aluminum shell bodies 1 through the insulating particles 8 and the connecting holes 7, thereby forming a complete aluminum shell body 1.

[0069] Furthermore, the tail end of the insulating particle 8 extends into the insulating plate 5, and the connecting bolt and the aluminum shell body 1 can be further insulated by continuously arranging the insulating particles 8 and the insulating plate 5 in the length direction of the connecting bolt.

[0073] The pipe connection assembly is arranged on the end of the output row 2 away from the aluminum shell body 1, and is suitable for connecting the inlet and outlet of the heat dissipation pipe 10 with the outside world, so as to facilitate the circulation of the heat dissipation medium in the heat dissipation pipe 10, thereby taking away the heat transferred to the heat dissipation pipe 10.

[0074] Furthermore, the pipeline connection assembly includes:

[0075] A connecting cavity 11 is arranged on one end of the output row 2 away from the aluminum shell body 1, one end of the connecting cavity 11 is respectively connected to the inlet and outlet of the heat dissipation pipeline 10, and the other end of the connecting cavity 11 is connected to the outside;

The lock-type water nozzle 14 can be conveniently connected to the outside world and can be conveniently connected to the circulating heat dissipation medium. The protrusion 16 and the groove 17 are adapted to each other. When the lock-type water nozzle 14 needs to be screwed to the connection block 12, or the water nozzle nut 15 is tightened on the lock-type water nozzle 14, the protrusion 16 can limit and block the connection block 12 to prevent the connection block 12 from rotating relatively in the connection cavity 11.

[0080] Furthermore, the heat dissipation pipeline 10 and the connection block 12 are both made of copper. Copper has good thermal conductivity, which can accelerate the heat transfer of the aluminum shell body 1 and the heat dissipation of the heat dissipation pipeline 10.

[0081] Furthermore, the aluminum shell body 1, the output row 2 and the heat dissipation pipeline 10 are integrally cast. Compared with the existing method, the contact surface between the aluminum shell body 1 and the output row 2 is reduced, and the heat dissipation efficiency is accelerated.
