[0051] As shown in Figure 5As shown, the sealing gaskets are arranged between the condensing discs 4 in this embodiment, and the sealing gaskets can seal the edges of the accommodating cavities 11. Specifically, the sealing gaskets are arranged between the top condensing disc 41 and the middle condensing disc 42, between the middle condensing disc 42 and the middle condensing disc 42, and between the middle condensing disc 42 and the bottom condensing disc 43.

[0052] In order to increase the volume of the accommodating cavities 11, the opposite sides of the adjacent condensing discs 4 are provided with annular protrusions in this embodiment. Specifically, as shown in Figure 6 the bottom of the top condensing disc 41 is provided with an annular protrusion; as shown in Figure 7 the top and bottom of the middle condensing disc 42 are also provided with annular protrusions; as shown in Figure 8 the top of the bottom condensing disc 43 is provided with an annular protrusion. In the accommodating cavity 11 formed by the top condensing disc 41 and the middle condensing disc 42, the volume of the accommodating cavity 11 between the top condensing disc 41 and the middle condensing disc 42 can be increased due to the arrangement of the annular protrusion. In the accommodating cavity 11 formed by the middle condensing disc 42 and the middle condensing disc 42, the volume of the accommodating cavity 11 between the middle condensing disc 42 and the middle condensing disc 42 can be increased due to the arrangement of the annular protrusion.

When the liquid is in the accommodating cavity 11 between the top condensing disc 41 and the middle condensing disc 42, the accommodating cavity 11 between the top condensing disc 41 and the middle condensing disc 42 can accommodate more liquid due to the arrangement of the annular protrusion. Then, the liquid in the accommodating cavity 11 between the top condensing disc 41 and the middle condensing disc 42 flows through the flow guide channel, and the liquid reaches the accommodating cavity 11 between the middle condensing disc 42 and the middle condensing disc 42. Then, the liquid successively flows through the accommodating cavities 11 between the middle condensing discs 42 at different heights, and finally, the liquid is released to the outside through the discharge channel on the bottom condensing disc 43.

[0055] Of course, in the process of the liquid passing through the different containing cavities 11, the liquid of another temperature flows inside the different condensing plates 4 through the pipe interfaces, and the liquid completes heat exchange inside the condensing plates 4 and on the outer surfaces of the condensing plates 4.
