Floating coil heat exchanger heat exchange device

The utility model discloses a floating coil heat exchanger heat exchange device which comprises a shell assembly and a cooling assembly, a water inlet pipe and a water outlet pipe of the shell assembly are installed on the two sides of a shell, and a steam inlet pipe and a steam outlet pipe of the cooling assembly are installed on a steam inlet and a steam outlet of the shell respectively. The fins are fixedly connected with the steam inlet pipe and the steam outlet pipe respectively and located on the outer side, and the floating coils are communicated with the steam inlet pipe and the steamoutlet pipe. Cold water is added into the shell through the water inlet pipe, high-temperature steam is added into the steam inlet pipe and enters the steam outlet pipe through the floating coil pipeto be discharged, and the fins installed on the steam inlet pipe and the steam outlet pipe exchange heat with the cold water in the floating coil pipe and the shell. The fins can increase the heat exchange area so as to improv
