Abstract

The invention relates to an internal heat type swirl fin sleeve gas water heater. An outer sleeve is provided with an intermediate sleeve and an inner sleeve, both ends are fixed and sealed by upper and lower sealing ends, and the outer sleeve and the intermediate sleeve are connected. There is a water heating layer between the middle sleeve and the inner sleeve, a flame layer is between the middle sleeve and the inner sleeve, and the inner sleeve is a water mixed flow layer. A combustion chamber is formed between the upper end cover and the upper sealing end, the combustion chamber is communicated with the flame layer through the fire inlet above the upper sealing end, the lower end of the lower sealing end is provided with a lower end, and a set is formed between the lower sealing end and the lower end. The smoke chamber and the smoke collecting chamber are communicated with the flame layer through the smoke outlet on the lower sealing end. The invention simplifies the structure of the heat exchange device of the water heater, improves the heat exchange efficiency, and avoids the problems of unsustainable water supply and insufficient water supply caused by excessive temperature.

Description

technical field [0001] The invention relates to a heat exchange device for a gas-fired water heater, in particular to a heat exchange device for an internal-heating swirl vane sleeve gas water heater. Background technique [0002] Along with the tension of power supply, now the whole country vigorously promotes gas water heaters, the main problem of existing gas water heaters is: the water heater heat exchange device is to transfer heat to water by the water pipe with fins in the baking water tank. On the one hand, this heat exchange method is inefficient, and the design and manufacture of the heat exchange device to improve efficiency is very complicated, and the cost is high due to the use of expensive materials; on the other hand, the flame heats the water and also heats the outer wall of the water tank, so The water heater has to stop every time it works, and there is a great limit to the water output of the water heater. The larger the displacement of the same type of w...
