In the present embodiment, the horizontal reciprocating bending means that the first bending portion 11 and the second bending portion 12 are respectively bent in a reciprocating manner along a horizontal plane in the front-rear and left-right directions.

In other words, the plurality of layers of reciprocally bent condensation pipes 10 may be regarded as a first bent portion 11 horizontally reciprocally bent and a second bent portion 12 horizontally reciprocally bent alternately arranged in sequence in the vertical direction. The vertical direction corresponds to the up-down direction indicated in fig. 1.

As shown in fig. 1 and 2, the heat dissipation and drainage layer includes first fins 20 and second fins 30 alternately arranged in sequence, the first fins 20 include first slopes 21 inclined toward a first direction, and a first drainage port 22 is disposed at a lowest position of the first slopes; the second fin 30 includes a second slope 31 inclined toward the second direction, and a second drain opening 32 is provided at a lowest position of the second slope 31; wherein the first direction is opposite the second direction such that a maximum distance is provided for water to trickle from the first drain opening toward the second drain opening.

In the present embodiment, the first direction is inclined, for example, toward the lower left, and the second direction is inclined, for example, toward the lower right. The water flows out from the higher position of the first inclined surface 21, through the first inclined surface 21 toward the first drain opening 22 at the lower left, flows into the higher position of the second fin 20 at the lower part, and flows into the second drain opening 32 at the lower right through the guidance of the second inclined surface 22.

100 and 200.

Referring to the condensing apparatus 300 shown in fig. 7, the plurality of layers of reciprocally bent and arranged condensing tubes include a plurality of layers of vertically reciprocally bent third bent portions 310, and any two adjacent layers of the third bent portions 310 are connected to each other by a fifth bent portion 312 extending along the horizontal direction, wherein the adjacent fifth bent portions 312 are symmetrically disposed along the front-back direction.

In this embodiment, the vertical reciprocating bending means that the third bending portion 310 is bent back and forth along a vertical plane in which the front, back, up and down directions are located.

In other words, the plurality of layers of reciprocally bent condensation pipes in the condensation device 300 can be regarded as the third bending parts 310 which are vertically reciprocally bent and arranged at intervals in sequence in the horizontal direction. The horizontal direction corresponds to the left-right direction indicated in fig. 7.
