In domestic gas-fired water heater use procedure, the heat energy that fuel gas buring produces, after over-heat-exchanger, has partial heat energy to be taken away cannot utilize by air-flow, heat exchanger usefulness is not high enough, not only reduce the heat exchange efficiency of gas heater, also waste resource, the use cost of gas heater is remained high.
Summary of the invention
The utility model provides the efficient heat exchanger in a kind of domestic gas-fired water heater, from the upper surface of the top finned tube of heat exchanger, all for pipe upper surface fins are tilted towards a direction, fin machining is formed arch, fin projection on finned tube is longer, and the arch width that fin machining is formed is larger; The protruding fin of fin above finned tube is shorter, and the curved width of arc that fin machining is formed is less.This product is by after carrying out above processing to fin, and the arch fin on finned tube can be formed the hot gas of discharging and stop, force the thermal current of discharge along the arch lower surface flowing of fin and spray from the both sides of arch fin, the upper surface of directive finned tube.Thermal current produces heat exchange with curved fins and finned tube upper surface again, and the heat energy in hot gas must be collected again, and the heat energy that fuel gas buring produces obtains official's efficiency utilization, and the heat exchanger (water tank) in water heater will become more efficient more energy-conservation.
For solving the problems of the technologies described above, this application provides the efficient heat exchanger in a kind of domestic gas-fired water heater, comprise main frame body, the heat exchanger tube described main frame body being provided with several heat exchange fins and strung by multiple described heat exchange fin and the U-tube being communicated with heat exchanger tube described in each, bending part is processed at the top of described heat exchange fin.
The bending part of described all heat exchange fins is all towards side.
Described bending part is semicircle arcuation.
Described heat exchange fin is installed towards lopsidedness, and heat exchange fin entirety is in arch.
The application has following technique effect or advantage:
From the upper surface of the top finned tube of heat exchanger, tilted by all for pipe upper surface fins, fin machining is formed arch towards a direction, the fin projection on finned tube is longer, and the arch width that fin machining is formed is larger; The protruding fin of fin above finned tube is shorter, and the curved width of arc that fin machining is formed is less.This product is by after carrying out above processing to fin, and the arch fin on finned tube can be formed the hot gas of discharging and stop, force the thermal current of discharge along the arch lower surface flowing of fin and spray from the both sides of arch fin, the upper surface of directive finned tube.Thermal current produces heat exchange with curved fins and finned tube upper surface again, and the heat energy in hot gas must be collected again, and the heat energy that fuel gas buring produces obtains official's efficiency utilization, and the heat exchanger (water tank) in water heater will become more efficient more energy-conservation.
