Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model energy-saving gas water heater is further described:
Accompanying drawing 1 is the partial structurtes schematic diagram of the utility model gas heater;
Accompanying drawing 2 is the A-A cutaway view of Fig. 1;
Among the figure: 1, smoke baffle plate 2, condenser 21, water inlet/outlet pipe 3, heat exchanger 31, water inlet 32, delivery port 4, transition conduit 5, condensation-water drain 6, tube connector 7, heat exchanger fin 8, casing 9, smoke exhaust pipe 10, condenser straight tube.
The specific embodiment
Embodiment 1:
Shown in accompanying drawing 1,2, in the partial structurtes schematic diagram of the utility model energy-saving gas water heater, condenser 2 is positioned at the front side or the rear side of water heater heat exchanger 3, the bottom of heat exchanger 3 is provided with water inlet 31 and delivery port 32, the top of condenser 2 links to each other with heat exchanger 3 by transition conduit 4, and the bottom links to each other with the water inlet 31 of heat exchanger 3 by tube connector 6.Condenser 2 comprises casing 8 and is arranged on some heat exchanger fins of vertically arranging 7 in the casing 8 and the condenser straight tube 10 that passes heat exchanger fin 7.This metal tube is connected to form by straight tube and U-shaped pipe, and an end of condenser straight tube 10 is connected with extraneous water source by the water inlet pipe on the condenser 21, and the other end is connected to tube connector 6.Also be provided with the fixedly smoke baffle plate 1 of heat exchanger fin 7 in the casing 8, the top of smoke baffle plate 1 is fixed on the casing 8, leave discharge flue between the bottom of smoke baffle plate 1 and heat exchanger fin 7 and the casing 8, casing 8 is separated into some fume inlet passages and the discharge flue that is interconnected every bright plate 1 like this.Be provided with the smoke exhaust pipe 9 that is communicated with ambient atmosphere at the top of casing 8, the end of discharge flue.And the extreme lower position of casing 8 bottoms is provided with condensation-water drain.Transition conduit 4 is the inverted U structure, and its end is communicated with casing 8 and the heat exchanger fin 7 in the casing 8, and the other end is communicated with heat exchanger.Like this, the inlet of fume inlet passage links to each other with transition conduit 4, and the outlet of discharge flue links to each other with smoke exhaust pipe 9.
The high-temperature flue gas that heat exchanger 3 is discharged enters condenser 2 through transition conduit 4 from condenser 2 tops, when high-temperature flue gas flows through the fume inlet passage of condenser 2, the heat of high-temperature flue gas absorbs the absorption of the water in conduction, heat convection are condensed device straight tube 10 again through be condensed device heat exchanger fin 7 of heat convection.
In this New-type water heater, its water (flow) direction is: cold water enters condenser 2 from the water inlet pipe 21 of condenser 2, and the tube connector 6 between condenser 2 and heat exchanger 3 enters heat exchanger 3.Hot water is flowed out by delivery port 32 after heat exchanger 3 heat exchange.Condensed water drippage direction and high-temperature flue gas flowing in condenser is identical, the high-temperature flue gas that fuel gas buring produces is through after the heat exchange, temperature reduces, partial liquefaction becomes water droplet, go downstream from heat exchanger fin 32, and discharge from the condensation-water drain 5 of casing 8, last cooled smoke is directly discharged from smoke exhaust pipe 9, or the prolongation pipeline that connects on the smoke exhaust pipe 9 discharge.Therefore the running water in the condenser straight tube 10 is able to preheating, and flows to heat exchanger 3 through tube connector 6, thereby improves the operating efficiency of gas heater, reaches purpose of energy saving.And high-temperature flue gas is lowered the temperature in heat exchanging process and partial liquefaction, makes molecule entrained in the flue gas deposit, and reaches the purpose that purifies air, and reduces the pollution of environment.This energy-efficient gas heater is more suitable under the present energy growing tension situation demand to product.Arrow is depicted as water (flow) direction and high-temperature flue gas flow direction among the figure.
Condenser among the above embodiment is arranged between the heat exchanger of water inlet pipe 21 and water heater, that is to say, cold water through the condenser preheating, heats in entering heat exchanger earlier, and it is the preferred forms of technical solutions of the utility model.
Embodiment 2:
As shown in Figure 3, condenser 2 also can be connected between the heat exchanger 3 of outlet pipe 21 and water heater, that is to say, cold water is entered by the water inlet 31 of heat exchanger, earlier through over-heat-exchanger 3 heating, pass through tube connector 6 again, enter condenser 2 and high-temperature flue gas heat exchange or insulation, the outlet pipe 21 from condenser 2 bottoms flows out at last.Arrow is depicted as water (flow) direction and high-temperature flue gas flow direction among the figure.This structure is not so good as embodiment 1 to the recovering effect of high-temperature flue gas heat energy, but it can realize the recycling of high-temperature flue gas heat energy equally, improves the operating efficiency of gas heater, reaches purpose of energy saving.Simultaneously, compare with the water heater of equal effect, its longitudinal size is more suitable for the needs of Modern Family's story height.
