In the utility model, the clapboard is added in the combustion chamber, so that the combustion can be adequate, the heating temperature is even, and the heat efficiency is improved; the smoke channel is arranged at the top of the case originally, while in the utility model, the smoke channel is changed to be arranged at the side of the case, therefore, the area of heat exchange between the hot water machine and the heat exchanger is enlarged, so as to improve the efficiency; in addition, the evaporation and air burning caused by original poor effect of partial cycle can be avoided.
Description
Technical field
The utility model relates to boiler technology, relates in particular to a kind of employing and closes the atmospheric hot-water machine that circulation realizes heat exchange.
Background technology
Domestic present employed atmospheric hot-water boiler is the vertical fire-tube type water heater for being made up of burner, combustion chamber, smoke pipe, boiler body, automatic water-supply and auto temperature controlled system mostly.The steam boiler of DIN board boiler and other national designed manufacturing of the world and hot-water boiler are horizontal fire tube boiler.Above-mentioned two kinds of designs are positive displacement, and promptly heated medium remains static in container, and heat transmission is that heated medium thermal conductivity factor under static state determines, thereby heat transfer rate is slow, and efficient is low.U.S.'s Cray is stepped on steam generator and has been changed above-mentioned design, it turns to a metal tube in the multilayer involute coil pipe that is serially connected, flame after the fuel combustion and hot flue gas move outside metal tube, heated medium flows in pipe, heated medium is absorbed heat at the volley, and enlarged heating surface area.But its weak point is that flame and the smoke movement distance after the burning is too short, at residing time in furnace very little, makes the heat energy after the conversion can not get fully absorbing, and the flue-gas temperature of discharging in the chimney is up to 350 ℃, and its heat energy utilization rate is low, and energy resource consumption is big.
The utility model content
The purpose of this utility model provides a kind of sufficient combustion, the heat exchanger effectiveness height, and it is good to heat the medium convection effects, and the hot water machine of compact conformation.
The technical solution of the utility model is: be made up of the combustion chamber of establishing in cabinet, the cabinet, burner, flue, the heat-exchange device that is arranged in the cabinet, heat-exchange device comprises heat exchanger and the water tank that is interconnected, external heat exchanger serial connection heat exchanger and water tank, described flue is located on the sidewall of cabinet one side, establish a upright dividing plate in the described combustion chamber, the lower partition is provided with some through holes or groove, burner is communicated with one of them chamber, another chamber is communicated with flue, and heat exchanger is located between another chamber and the flue.
Described heat exchanger is made up of some water pipes of upper and lower water box and the upper and lower water box of connection, and water inlet is established at the upper water box top, is horizontally disposed with some water pipes in the upper water box, the water pipe of the nearly fire end of the corresponding heat exchanger of an end of water pipe, other end joining water box.
Described flue is L shaped, and the flat pipe place of corresponding straight tube position establishes dodge gate.
Be provided with water jacket in the side plate of described cabinet, top board, the base plate, the water jacket joining water box.
The utility model has increased dividing plate in the combustion chamber, make that burning is more abundant, and heating-up temperature is more even, has improved the thermal efficiency; Flue has changed the structure that in the past is arranged on the case top, is arranged on the case side, and this has increased the area that carries out heat exchange with interchanger, has further improved efficient; The structure of heat exchanger, overcome in the past and can produce the local circulation weak effect, and the vaporization that occurs, the empty phenomenon of burning, characteristic according to the water convection current, be horizontally disposed with outlet pipe at upper water box, like this, the water that temperature is high can flow to water tank by this pipeline, and the water inlet of upper water box advances water at low temperature and replenishes water level in the interchanger.In order to reduce heat loss, be provided with water jacket at the cabinet wall, the heat that outwards distributes in order to the absorption machine chamber interior wall; Owing in the flue carbon distribution, impurity are often arranged, the utility model is provided with dodge gate in the flue bottom, can make things convenient for the blowdown impurities removal, further improves the thermal efficiency.
The utility model is compared maximum superiority with conventional boiler be that heating surface area in the unit volume is big, and volume is little, and is in light weight, and investment cost is few.Unit volume is 30% of a conventional hot-water boiler, and weight is 35% of conventional boiler.Body is a stainless steel structure, no pressure in the body of heater, and it is reliable to guarantee to be perfectly safe.Unit is a fuel with natural G﹠O, adopts high efficiency import burner, makes fuel combustion more complete, and toxic emission is better than national standard.The multilevel security defencive function, intelligentized temperature sensor self-diagnosis of trouble ability, in case unit is overheated, the unit hard stop is also reported to the police.Life-span is long, through high-velocity fluid, makes that the particulate in the liquid is difficult to deposit fouling in the body of heater.And heat exchanger no-rotary part and easy leakage in the hot water unit, vibration, overheated, overvoltage, equipment such as aging, the equipment self freedom from repairs.
