Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] Such as figure 1 , shown in 2: the internal heating type swirl vane sleeve gas water heater of the present invention includes an outer sleeve 18, an intermediate sleeve 19, an inner sleeve 20, an upper end cover 1, a combustion chamber 2, a fire inlet 3, and an upper sealing end 4. The water heating layer 12 between the outer sleeve and the middle sleeve, the flame layer 5 between the middle sleeve and the inner sleeve, the water mixing layer 14 inside the inner sleeve, the smoke outlet 6, and the smoke collection chamber 7 , smoke outlet 8, lower end 9, lower sealing end 11;
[0021] The outer sleeve 18 is provided with an intermediate sleeve 19 and an inner sleeve 20 in turn, and the two ends are fixed and sealed by the upper sealing end 4 and the lower sealing end 11. The side of the outer sleeve 18 is provided with a water inlet 10, and the ...

The invention relates to an internal combustion type helical fin sleeve gas water heater. An intermediate sleeve and an inner sleeve are arranged in an outer sleeve, the two ends of the sleeves are fixed and hermetically connected by an upper seal end and a lower seal end, a water heating layer is arranged between the outer sleeve and the intermediate sleeve, a flame layer is arranged between the intermediate sleeve and the inner sleeve, a water mixing layer is formed in the inner sleeve, the water heating layer is communicated with the water mixing layer through a guide water pipe, an upper end cover is arranged at the upper end of the upper seal end, a combustion chamber is formed between the upper end cover and the upper seal end, the combustion chamber is communicated with the flame layer through a flame inlet on the upper seal end, a lower end is arranged at the lower end of the lower seal end, a smoke collecting cavity is formed between the lower seal end and the lower end, the smoke collecting cavity is communicated with the flame layer through a smoke outlet on the lower seal end, a flame helical fin is arranged in the flame layer, and a water helical fin is arranged in the water heating layer. The structure of the heat exchange device of the water heater is simplified, the heat exchange efficiency is improved, and the problem that continuous water supply failure and insufficient water supply are caused by the too-high temperature is avoided.
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...
