The larger volume is convenient for reducing the resistance and providing large current, because the first metal sheet 41 is stacked, the right lower electrode 32 can bear proper pressure, and because the second metal sheet 42 is slightly raised, the step fall between the second metal sheet 42 and the block structure can abut against the auxiliary positioning steel ring 70.

The first metal sheet 41 is an aluminum sheet, and the second metal sheet 42 is an iron sheet. The connection between the first metal sheets 41 is ultrasonic welding, and the block structure and the second metal sheet 42 are conventional electric welding.

lower electrodes

22 and 32, it is not recommended to directly connect the left and right

lower electrodes

22 and 32 by a wire. In order to provide a sufficiently large current and reduce current loss, in the present embodiment, the left transition piece 24 and the right transition piece 34 are both conductors, and a left lower conductor and a right lower conductor 35 are respectively disposed below the left transition piece 24 and the right transition piece 34, and a left upper conductor 23 and a right upper conductor 33 are respectively disposed above the left transition piece 24 and the right transition piece 34.

In this embodiment, it can be seen that the lower h-shape of the left and right mounting

seats

21 and 31 also respectively support the side surfaces of the left and right

upper conductors

23 and 33.

Preferably, the lengths of the front end and the rear end of the left transition piece 24 and the right transition piece 34 are 30-50cm, the thickness of the front end and the rear end of the right transition piece 34 is 1-2cm, and the inner diameter of the liquid channel 61 is 70-80% of the thickness of the corresponding left transition piece 24 or right transition piece 34.

Wherein the backwater is bent and hidden in the frame 10; since the left and

right transition pieces

24, 34 may move a partial distance left and right, an elastic tube is used for a portion or the entirety of the return bend to provide the appropriate amount of deformation. In another embodiment, left transition piece 24 and right transition piece 34 are each provided with two liquid passages 61, see FIG. 5 in particular, where the arrows indicate the direction of media flow. In this embodiment, the medium can carry away more heat.

Preferably, the inlet and outlet of the liquid passage 61 are welded with adapter tubes, and the end of the pipe 62 is wrapped with the adapter tubes and then reinforced by winding collars around the end of the pipe 62. This design significantly improves the tightness of the conduit 62 and the liquid channel 61. Specifically, the adapter tube is inserted into the liquid channel 61 and then welded in a circle in the circumferential direction of the adapter tube, the welding part is sealed, and the pipeline 62 can be locked in the circumferential direction of the pipeline 62 by using a clamping ring after being wrapped on the adapter tube.

The power supply module supplies power, and the breach that the heavy current passed through steel ring 70 forms the current loop, and the live time lasts about 3s, and the breach of steel ring 70 heats and melts and fuses again after the power module outage. The second pushing mechanism 27 and the third pushing mechanism 37 are released, the left upper electrode 26 and the right upper electrode 36 are lifted, the first pushing mechanism 12 is reset, the right mounting seat 31 is far away from the left mounting seat 21, and at this time, the steel ring 70 after welding can be taken away.
