Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, and provides a kind of compact conformation reasonable, and heat exchange is abundant, the thermal efficiency is high, heat loss is little, and firing rate is fast, saves the efficient energy-saving gas heat exchanger of combustion gas.
The utility model is achieved in that it has a housing, in housing, be evenly equipped with many row's heat exchanger tubes, be provided with the heat absorption mouth in housing outer surface, exhaust opening, water inlet and delivery port, its special character is: be provided with water jacket in inner walls, water inlet and delivery port communicate with water jacket respectively, described many row's heat exchanger tubes are located between the interior bottom of housing and the adjacent two row's heat exchanger tubes and are staggeredly located, the two ends of heat exchanger tube communicate with water jacket respectively, be provided with snakelike flue at the housing internal upper part, snakelike flue outlet communicates with exhaust opening, be provided with the secondary heat exchange device along snakelike flue in housing, described secondary heat exchange device communicates with water jacket.
Above-mentioned efficient energy-saving gas heat exchanger, described secondary heat exchange device is to be made of many rows straight tube, and the two ends of straight tube communicate with water jacket.
Above-mentioned efficient energy-saving gas heat exchanger is arranged heat exchanger tube place in the surface of shell correspondence more and is provided with the clean-up port, and the place is equipped with closure plate in the clean-up port, so that impurity and incrustation scale in the cleaning heat exchanger tube.
Above-mentioned efficient energy-saving gas heat exchanger, described heat exchanger tube are three～six rows.
Above-mentioned efficient energy-saving gas heat exchanger, row's spacing of described heat exchanger tube is 6～15mm.
Above-mentioned efficient energy-saving gas heat exchanger, described secondary heat exchange device is pipe or rhumbatron.
The utility model has the advantages that: be staggeredly located because heat exchanger tube is located in the housing between bottom and the adjacent two row's heat exchanger tubes, make heat exchanger tube can fully absorb the heat that flame combustion produced of heat absorption mouthful, carry out first heat exchange with water in the heat exchanger tube; Owing to be provided with snakelike flue at the housing internal upper part, make the heat absorption mouthful the flue gas that flame combustion produced and the secondary heat exchange device in carry out the secondary heat exchange, make full use of the waste heat in the flue gas, good effect of heat exchange, thermal efficiency height, heat loss are little, firing rate is fast, the outlet water temperature can reach more than 60 ℃, save combustion gas greatly, and compact conformation is reasonable, applied widely, can be used for heating, bathing etc.
