In addition, the spiral structure is relatively compact, saving internal space of the device.

[0034] Working principle:

[0035] First, when the Qi hot water boiler is working, water flows from the water inlet pipe into the spiral heat exchanger 2, and the heat exchange tube 21 heats the water. At the same time, the blower 4 blows air to the boiler body 1 through the pipe 3 to promote the combustion of fuel in the boiler body 1. The flue gas generated by the combustion enters the condenser 6 through the flue gas pipe 5. The flue gas will cool and the water vapor will condense into liquid water, while other gas components will be discharged into the air through the condenser 6. The water pump 82 will flow the condensed liquid water into the water tank 84 through the water supply pipe 83, and then flow back to the spiral heat exchanger 2 through the water supply pipe 85 to complete the water circulation, so as to continue the steam-water heat exchange process, continuously provide heat to the system and realize heat exchange. At this point, the entire work process ends.
