The heat exchange chamber 100 has a box shape, and the combustion chamber 200 is located below the heat exchange chamber 100, i.e., below the bottom of the outer shell 110. The heat exchange tube 300 is installed in the heat exchange chamber 100, the heat exchange tube 300 is in a coil shape and spirally extends from bottom to top, and two ends of the heat exchange tube 300 extend out of the heat exchange chamber 100 to form a water inlet 310 and a water outlet 320 respectively. The heat exchange structure is applied to water heating equipment, wherein one embodiment can be as follows: the heat exchange chamber 100 is separated from the combustion chamber 200 by the bottom of the outer shell 110, the heat exchange chamber 100 is filled with superconducting fluid, and the heat energy generated by the combustion of the burner 210 is transmitted to the superconducting fluid in the heat exchange chamber 100 through the outer shell 110. External cold water enters the heat exchange tube 300 through the water inlet 310 and flows in a spiral manner in the heat exchange chamber 100 along with the heat exchange tube 300. The water is heat-exchanged with the superconducting fluid through the heat exchange pipe 300, so that the water is heated or heated to a steam state and then flows out of the water outlet 320.
