[0002] With the development of the economy, people's requirements for quality of life are getting higher and higher, including the energy saving and safety of bathing and showering.

[0003] There are many types of water heaters, among which high-power gas water heaters use the energy of natural gas combustion to generate heat energy. They can provide different hot water needs of each room in the hotel with large water volume, high water pressure and constant temperature 24 hours a day. However, gas water heaters will produce a lot of smoke during the combustion process. The heat carried by the smoke is directly discharged into the atmosphere, which is wasteful, energy-intensive and has the problem of low utilization rate. Therefore, it is necessary to strengthen the utilization of smoke. Therefore, we propose a dual-channel smoke-water heat exchanger. Utility Model Content
