As a preferred scheme, one end of each coiled pipe assembly, which is close to the water outlet header, is provided with a pipe clamp for positioning a coiled heat exchange single pipe.

As a preferred scheme, a plurality of positioning pipe clamps are arranged on the connecting pipes which are arranged in parallel.

The utility model has the advantages that: because the connecting plate of the mounting seat on the wall of the back cigarette well is matched with the bending section through the clamping groove in the clamping plate at the bending part of the coiled pipe, the bending section is directly clamped into the clamping groove to realize the installation of the coiled pipe assembly and the back cigarette well wall, and then the maintenance and the disassembly at the later stage are convenient.

Because the pipe clamp of the snakelike heat exchange single pipe of location is arranged at the one end that every snakelike pipe assembly is close to a water header, and is equipped with a plurality of location pipe clamps on the connecting pipe to fix a position reinforcing because of snakelike heat exchange single pipe and connecting pipe, avoid the displacement because of being heated the deformation and leading to.
