At present, the main heat exchanger of most of gas-heating water heater is traditional pipe fin structure, be heat exchanging water pipe's appearance cover one row or number row radiating fin, by fuel combustion flame heat radiating fin, thereby heat is passed to flow through water in the water pipe of heat exchanger tube heating again, the heat exchanger heat transfer area of this structure is smaller, and in use for some time, easily produce the crack between radiating fin and heat exchanging water pipe, it is bad to conduct heat, the thermal efficiency of this water heater is lower, and it is more to waste energy.
Be energy savings, the boundling tubular type water heat exchanger (patent No.: 00264714.1) propose a kind of heat exchanger that is used for gas heater, it is to have the close pipe of many row's multilayers to be staggered together in a tubular space that is surrounded by some blocks of plates, communicate in each pipe, always hold first to fetch one in water pipe for two of pipe and pick out water pipe, combustion gas is in the bottom burning of pipe, the direct heating surface (area) (HS of this heat exchanger is big, the thermal efficiency is higher has saved combustion gas, but weak point is a heat exchanger tube is subjected to directly smouldering of high temperature cigarette flame, be etched easily, be not durable; The patent No. is that 91107914.9 Chinese patent has proposed a kind of chimney water jacket gas fired water heater, it constitutes a cigarette flame flowing space by chimney, fin and core pipe, chimney and outer tube are formed a sealed water jacket, conduct heat to the water in the water jacket of flowing through by the heating smoke tube, this design overcome to a great extent the thermal efficiency low, waste energy and short-life problem, but because the current direction in the water jacket is indefinite, convection current is stronger, cold water time of staying in water jacket is indefinite, cause the cold water heating uneven, be difficult to obtain desirable temperature required hot water.
The content of utility model
The purpose of this utility model provides the novel cylinder type condensed heat exchanger of a kind of structure, solves problems such as existing heat exchanger heats is inhomogeneous, the thermal efficiency is low, waste energy and be not durable.
The purpose of this utility model is achieved in that
A kind of cylinder type heat exchanger, one cylinder is arranged, be provided with heat exchange bar in the cylinder, the coiling of cylinder outer surface has helix tube, the two ends of helix tube are connected with water inlet pipe, outlet pipe respectively, it is characterized in that: helix tube is to be made of cylinder and outer sleeve and the spiral plate that is provided with between them; Several heat exchange bar are arranged, and an end of every heat exchange bar is connected on the cylinder internal face, and its other end cantilevered places cylinder inside.
The heat exchange bar in same cross section divides four groups orthogonally to arrange in horizontal and vertical mode in the cylinder.
As optimization, heat exchange bar is provided with the different densities packet section on the cylinder axis direction, encrypts gradually to the distribution of exhaust opening heat exchange bar from advancing mouth.
As optimization, heat exchange bar is reserved an axial passage in the cylinder inside center.
As optimization, described outer sleeve has access panel.
As optimization, described outer sleeve outer end is provided with seal groove, makes itself and external piece become axle to be connected.
As optimization, water inlet pipe becomes conjoined structure and has enough support strengths with outlet pipe with outer sleeve, and the outer end of water inlet pipe and outlet pipe is provided with installs the spiral shell head, and such design can be supported water inlet pipe and outlet pipe as installing, save the installation support component.
During use, the utility model is connected with exhaust chamber/pipe with the combustion chamber, its operation principle is: by the heat of heating stove combustion chamber fuel combustion generation, heating cylinder inwall and inner heat exchange bar thereof, cold water enters helix tube from water inlet pipe, rises in the helix tube inside turn, absorbs the heat transfer by the cylinder body wall in uphill process, water temperature raises gradually, and what arrive that delivery port flows out through outlet pipe again is exactly required hot water.
The utility model has following characteristics:
Helix tube is provided with spiral plate and forms between cylinder and outer sleeve, helix tube inwall and cylinder body wall are same one, and the water pipe heating surface area of this structure obviously increases;
Helix tube is coiled on the cylinder outer surface, has increased pipe range, makes the water in the flowing pipe obtain sufficient heat time heating time, has improved the thermal efficiency of heat exchanger;
Heat exchange bar is provided with the different densities packet section on the cylinder axis direction, strengthens the resistance of flow of flue gas, makes the abundant heat exchange of flue gas and heat exchange bar, has utilized condensation heat of flue gas, improves heat exchange efficiency;
Water has only a flow direction in pipe, with flue gas heat exchanger time basically identical, heat more even;
Heat exchanger tube is not subjected to directly smouldering of high temperature cigarette flame, is difficult for being etched, thus durable in use;
Helix tube outer wall both sides have removable cover plate, are convenient to clean and maintenance;
The outer end is provided with seal groove, makes itself and external piece form axle and is connected, and connects more reliable;
In sum, the utlity model has homogeneous heating, thermal efficiency height, energy savings, durable in use, clean the advantage of easy to maintenance and environmental protection etc.
