[0021] A side baffle 14 is provided inside the first working tube 1 , and one end of the side baffle 14 is connected to the side baffle 15 .

[0022] The side partition plate 14 is provided to divide the interior of the first working tube 1 into two parts, the upper and lower parts, which are connected by the semicircular plate 3, thereby increasing the heat medium path.

[0023] Among them, a first partition plate 4 and a second partition plate 41 are arranged inside the first working tube 1. The first partition plate 4 is arranged on the inner wall of the first working tube 1, and a space is left between the first partition plate 4 and the side partition plate 14. The second partition plate 41 is arranged on the side partition plate 14, and a space is left between the second partition plate 41 and the inner wall of the first working tube 1.

[0024] By providing multiple groups of first partitions 4 and second partitions 41 to divide the interior of the first working tube 1 , the moving distance of the heat medium in the first working tube 1 is increased, thereby increasing the heat transfer time and thus improving the heat transfer efficiency.
