Abstract
The utility model relates to a plate type heat exchanging heating and water heating boiler, which belongs to small gas boilers. The utility model is formed by that heat exchanging units are punched with two convex-concave heat exchanging plates, the concave surfaces of the heat exchanging plates are opposite and are retained with gaps, the left ends and the right ends of the heat exchanging plates are sealed, and the upper ends and the lower ends of the heat exchanging plates are respectively inserted into an upper water tank and a lower water tank arranged on the heat exchanging plates and under the heat exchanging plates to be welded; a plate type heat exchanger is formed from a plurality of heat exchanging units distributed with equal distance; one side of the heat exchanger is provided with a combustion chamber; the tail of a flue which is opposite to the combustion chamber is provided with a smoke tank. The utility model has the advantages of large heat exchanging areas, high heat exchanging ratio, low heating central positions, high heating circular speeds, high heating speeds, energy saving and simple structure. Besides, the utility model is beneficial to natural circulation.
Description
A kind of plate-type heat-exchange heating-hot water two purpose boiler belongs to small gas boiler or gas heater.
Heat exchanger is the critical piece of miniature boiler or gas heater, and existing small gas boiler heat exchanger components mostly is water pipe heat exchange or smoke pipe heat exchange, and its shortcoming is that water capacity is big, and therefore, thermal inertia is big during heating, and firing rate is slow; Bathe when using hot water, can not utilize the water yield big, thereby the waste combustion gas.Existing heat exchanger volume is big, and structure is not compact, is difficult for being processed into the lower structure in thermal center (-tre), does not possess the Natural Circulation condition, mostly is mechanical cycles, needs second energy such as electric power.
The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, making can be at less heat transfer space, bigger heat exchange area is installed, hug room single household Natural Circulation heating system and a kind of compact conformation is provided to adapt to, its combustion chamber and heat exchanger opposing parallel arrange that to reduce the position that adds the thermal center (-tre) as far as possible, water storage volume water capacity little, that can not utilize is few, firing rate is fast, but can heating multiduty civilian heat power supply device such as bathing again.
The utility model is realized with following technical scheme: comprise heat exchanger, on, lower condensate sump, water-cooling wall and combustion chamber, it has two concavo-convex heat exchanger plates by the punching press of plate face, concave surface relatively and leave spacing, left and right sides sealing two ends, up and down both ends open and respectively plug-in mounting advance upper condensate sump and the lower condensate sump that its upper and lower is provided with, welding forms water-flowing path and constitutes a heat exchange unit, the parallel equidistant layout of a plurality of heat exchange units, its spacing forms exhaust gases passes, a plurality of heat exchange units of equidistantly arranging constitute plate type heat exchanger, plate type heat exchanger one side is provided with the combustion chamber, and flue afterbody place is provided with smoke box, the windproof enclosure of pegging graft on it.
Operation principle: the combustion gas burner of after regulating control, flowing through, behind the injection part air, in combustion chamber internal combustion heat release, form high-temperature flue gas, a heat part is carried out radiation heat transfer with water-cooling wall on every side and is passed to water, a part when flowing through the plate type heat exchanger flue and the plate type heat exchanger heat exchange pass to water, low-temperature flue gas is assembled in smoke box, drain into outdoor through hurricane globe, chimney, water enters lower condensate sump from the feedwater interface, flow through respectively then plate type heat exchanger, water-cooling wall absorb and become hot water behind the heat and enter upper condensate sump, flow out through delivery port and use.
The beneficial effect that the utility model had: 1, plate type heat exchanger plate face is stamped into rough planform, has increased heat exchange area, and tissue also stirs flue gas stream, increases the coefficient of heat transfer.2, the heat convection face is less than or equal to the combustion chamber height, therefore, has reduced the position that adds the thermal center (-tre), has increased the ringing pressure head, helps Natural Circulation, adapts to building single household Natural Circulation heating system.3, water capacity is little, and when heating was used, circulation rate was fast, and when using hot water, firing rate is fast, and does not need circulating power.4, simple in structure, easily make, and can form series of products.
Accompanying drawing:
Fig. 1 is plate-type heat-exchange heating-hot water two purpose boiler master cutaway view;
Fig. 2 is that figure cuts open in plate-type heat-exchange heating-hot water two purpose boiler office of overlooking;
Fig. 3 is that figure cuts open in plate-type heat-exchange heating-hot water two purpose boiler side-looking office.
A kind of optimum structure of the present utility model is provided by Fig. 1～Fig. 3, it is stamped into several two concavo-convex heat exchanger plates by the plate face, the two ends, the left and right sides of heat exchanger plates have the flanging to concave surface, two its flanging butt joint back welding of heat exchanger plates concave surface positioned opposite, on, following both sides opening, one narrow gap is arranged between plate, form water stream channel 9, the opening two ends insert respectively that joint welds in the identical shaped strip slit of upper condensate sump 3 and lower condensate sump 6, constitute a heat exchange unit, the parallel equidistant arrangement of a plurality of heat exchange units constitutes plate type heat exchanger 5, spacing between heat exchange unit is exhaust gases passes 10, water supply connector 4 is welded on the lower condensate sump 6, parallel with plate type heat exchanger 5 and be provided with combustion chamber 8 facing to its flue one side, do a water jacket samdwich with iron plate round plate type heat exchanger 5 and combustion chamber 8 and make water-cooling wall, water-cooling wall and upper condensate sump 3 weld together and constitute its boiler for dual purpose body, welding outlet pipe 7 on the upper condensate sump 3, smoke box 2 is arranged on the rear portion of body of heater flow of flue gas direction, and plug-in mounting hurricane globe 1 constitutes on the smoke box 2.
