  • the utility model belongs to the technical field of machinery, and relates to a heat exchange tube, in particular to a heat exchange tube.
  • Traditional gas wall-hung boilers are usually equipped with corresponding devices such as combustion chambers and heat exchangers.
  • the heat exchanger absorbs the energy generated by the combustion gas and transfers it to the cold water flowing through the heat exchanger through the inlet pipe. After heat exchange, the water temperature rises. Hot water is discharged from the water outlet pipe to realize the function of heating the water flow; the high-temperature flue gas generated by the combustion is pumped out of the room through the pipe chamber by the fan. Since the water vapor in the flue gas takes a considerable part of the energy, the thermal efficiency of the wall-hung boiler is limited, and the heat utilization rate is difficult to improve.
