Novel mute heat exchanger structure

The utility model provides a novel silent heat exchanger structure which comprises a shell, a water inlet pipe and a water outlet pipe, the upper end and the lower end of the shell are open, a heat exchange pipe set is arranged at the position, close to the top, of the shell, the two ends of the heat exchange pipe set are communicated with the water inlet pipe and the water outlet pipe respectively, and the shell is provided with a box shell, a heat insulation shell and an energy gathering shell from outside to inside. The box shell and the heat insulation shell are arranged in a spaced mode, the heat insulation shell and the energy gathering shell are arranged in a spaced mode, and a plurality of energy gathering concave faces protruding outwards are distributed on the inner wall of the energy gathering shell. The shell of the heat exchanger is of a three-layer structure, the heat exchange efficiency is improved, the noise problem is solved, and the problem that the water temperature is too high when a user
