A corresponding first mounting slot 111 is provided on the top of a group of side plates 11 opposite to the cylinder 1, and a second mounting slot 121 corresponding to the first mounting slot 111 is provided on the top plate 12. A partition 2 with a U-shaped cross section is provided between the two first mounting slots 111, which divides the cylinder 1 into an upper area 13 and a lower area 14. The partition 2 can be installed from the second mounting slot 121 into the first mounting slot 111. A primary heat exchanger 3 is provided in the lower area 14 for exchanging heat with the flame generated by the burner below. A secondary heat exchanger 4 is provided in the upper area 13 for exchanging heat with the high-temperature flue gas generated by the burner flame.

The two ends of the partition 2 are provided with side sealing plates 22, and the top of the partition 2 is provided with an upper sealing plate 23, forming a closed area and covering the secondary heat exchanger 4, so that the high-temperature flue gas can fully exchange heat with the secondary heat exchanger 4 for as long as possible. The upper sealing plate 23 is provided with a smoke exhaust port 231, which is used to discharge the flue gas that has completed the heat exchange with the secondary heat exchanger 4. A guide plate 24 is provided in the upper zone 13, and one end of the guide plate 24 is located above the smoke inlet 21. One end of the guide plate 24 is connected to the bottom of the two ends of the upper sealing plate 23 or the top of the two sides of the partition 2, and the other end extends to the bottom surface of the partition 2 and has a gap with the bottom surface of the partition 2, so as to guide the high-temperature flue gas entering the upper zone 13 from the smoke inlet 21 to the direction of the secondary heat exchanger 4, so that it can fully exchange heat with the secondary heat exchanger 4. In this embodiment, the guide plate 24 is arranged at both ends of the bottom surface of the upper sealing plate 23, and the guide plate 24 extends downwardly along the direction toward the inside of the partition 2 so as to guide the high-temperature flue gas entering the upper zone 13 from the smoke inlet 21 to the bottom of the upper zone 13, so that it can fully exchange heat with the secondary heat exchanger 4.

[0034] The integrated condenser structure provided by the embodiment of the utility model has a primary heat exchanger 3 and a secondary heat exchanger 4 integrated in a cylinder 1 formed by connecting four side panels 11.

In addition, the integrated condenser structure provided by the embodiment of the utility model has an upper zone 13 where the secondary heat exchanger 4 is located, which is basically a closed area, and is only provided with a smoke inlet 21 and a smoke exhaust port 231 for discharging the smoke after the heat exchange is completed, which prolongs the contact heat exchange time between the high-temperature smoke and the secondary heat exchanger 4 and improves the heat exchange efficiency. In addition, the guide plate 24 at the bottom of the upper sealing plate 23 guides the high-temperature smoke entering the upper zone 13 from the smoke inlet 21 of the partition 2 to the secondary heat exchanger 4 in the upper zone 13 (the direction of smoke flow is shown in FIG. 2 ). Figure 1 The upper area 13 formed by the partition 2 is used as a cavity for heat exchange between the high-temperature flue gas and the secondary heat exchanger 4. The front and rear sides of the upper area 13 are provided with smoke inlets 21. After the high-temperature flue gas has been heat exchanged in the primary heat exchanger 3, the smoke inlets 21 on the front and rear sides of the partition 2 flow in respectively, thereby realizing the functional characteristics of the double flow channel, increasing the amount of smoke entering, and further improving the heat exchange efficiency.

[0035] like Figure 1 , Figure 2 As shown, in one embodiment of the utility model, the first-stage heat exchanger 3 includes a plurality of first heat exchange tubes 31 and heat exchange fins 32. The cold water in the first heat exchange tube 31 absorbs the heat transferred by the flame generated by the burner below through the tube wall and the heat exchange fins 32, thereby increasing the temperature for use by customers. Preferably, the heat exchange fins 32 are in an inverted U shape, and the first heat exchange tubes 31 are passed through the heat exchange fins 32. In this embodiment, a heat exchange fin imitating the shape of a flame is adopted, which imitates the shape of a flame combustion process with a high middle and low sides, thereby achieving uniform heat exchange between the entire combustion flame and the heat exchange fins 32, and ensuring high energy efficiency output of the heat exchange process of the first-stage heat exchanger 3.

[0036] like Figure 3As shown, in one embodiment of the utility model, the secondary heat exchanger 4 includes a plurality of second heat exchange tubes 41, and the cold water in the second heat exchange tubes 41 can exchange heat with the high-temperature flue gas entering the upper zone to increase the temperature of the cold water in the second heat exchange tubes 41. The water in the second heat exchange tubes 41 is then passed into the primary heat exchanger 3 for double heating. The outer side of the side sealing plate 22 is provided with a first mounting portion 221 and a second mounting portion 222, and the first mounting portion 221 and the second mounting portion 222 are connected to the water inlet joint 5 and the water outlet joint 6, respectively. In this embodiment, the first mounting portion 221 and the second mounting portion 222 are grooves provided on the side sealing plate 22, and the mounting seats of the water inlet joint 5 and the water outlet joint 6 are respectively inserted into the first mounting portion 221 and the second mounting portion 222, and are combined with the water inlet joint 5 and the water outlet joint 6 into a closed cavity by, for example, brazing. The two ends of the second heat exchange tube 41 are respectively connected to the inner walls of the first mounting portion 221 and the second mounting portion 222, and are connected to the cavity to be connected to the water inlet joint 5 and the water outlet joint 6. Further, a certain number of mounting holes are provided at the bottom of the first mounting portion 221 and the second mounting portion 222, which are used to cooperate and connect with the end of the second heat exchange tube 41. In this embodiment, the first mounting portion 221 and the second mounting portion 222 are provided on one of the two side sealing plates 22, so that the water inlet joint 5 and the water outlet joint 6 are arranged on the same side of the cylinder 1 of the condensing heat exchange structure, which is convenient for saving space and connecting with other components.

[0037] like Figure 4 As shown, in a preferred embodiment of the utility model, the second heat exchange tube 41 is a bellows. The outer surface of the bellows is processed by rolling. When tap water flows through the inside, it exchanges heat with the high-temperature flue gas outside the tube. After the heat exchange, the high-temperature flue gas reaches a temperature below the dew point, thereby realizing the secondary condensation heat exchange function characteristics. The bellows can be connected to the mounting holes of the inner walls of the first mounting part 221 and the second mounting part 222 by brazing to ensure the sealing connection with the cavity of the first mounting part 221 and the second mounting part 222.

[0038] After the secondary heat exchanger 4 exchanges heat with the high-temperature flue gas, the water vapor in the high-temperature flue gas condenses to form condensed water, which falls into the cavity formed between the partition plate 2 and the side sealing plate 22. Figure 3 , Figure 7 As shown, in one embodiment of the utility model, a condensate interface 25 is provided at the bottom end of the side sealing plate 22, and the condensate interface 25 is connected to the condensate collecting device 7 through a condensate discharge pipe 26, and the condensate is introduced into the condensate collecting device 7 to prevent the condensate from affecting the heat exchange of the secondary heat exchanger 4 in the upper area.

[0039] Specifically, if Figure 5As shown, the condensate collecting device 7 comprises a tank body, and a first baffle 71 required for condensate liquid sealing is provided inside the tank body, the first baffle 71 extends upward from the bottom of the tank body, and there is a gap between the free end of the first baffle 71 and the top of the tank body, and the first baffle 71 divides the inside of the tank body into a first area 711 and a second area 712 connected at the top, the top of the first area 711 is provided with a condensate inlet 72, and the bottom of the second area 712 is provided with a condensate outlet 73. A second baffle 74 extending toward the bottom of the first area 711 is provided on the top of the tank body, and there is a gap between the free end of the second baffle 74 and the bottom of the tank body, and the second baffle 74 is spaced apart from the first baffle 71. An S-shaped flow channel is formed between the second baffle 74 and the first baffle 71, which can prevent floating objects from entering the second area 712 and blocking the condensate outlet 73. In order to give an alarm when the condensate outlet 73 is blocked, a water level detection device 75 is provided at the top of the first zone 711. When the condensate outlet 73 is blocked, the water level in the tank body continues to rise. When it rises to a predetermined height, the water level detection device 75 gives an alarm. The water level detection device 75 can be a water level sensor or a detection electrode. When the condensate cannot be discharged, the condensate level in the tank body gradually rises. When it reaches the water level point of the detection electrode detection position, the detection electrode is turned on to realize the function of blockage alarm. Furthermore, a sewage outlet 76 is provided at the bottom of the first zone 711 to discharge sludge and other debris.

[0040] In one embodiment of the present invention, the guide plate 24 is made of sheet metal, and its structural design is intended to change the flow direction of the high-temperature flue gas and guide the high-temperature flue gas to the secondary heat exchanger 4 to improve the heat exchange efficiency. Figure 3 As shown, the guide plate 24 is provided with a plurality of exhaust holes 241 for the outflow of high-temperature flue gas to avoid blocking the portion of the secondary heat exchanger 4 located above the guide plate 24 .

[0041] In order to air-cool the shell (i.e., the cylinder 1) of the condensing heat exchanger, Figure 1 , Figure 6 As shown, the side plates 11 of the cylinder 1 include a cover plate 112 and an inner plate 113 , and an air cooling channel 114 is formed between the two.

[0042] like Figure 7 , Figure 8As shown, the utility model also provides a gas water heater, including the above-mentioned integrated condenser structure, and also including a combustion system 8 and an air supply system 9 located below the integrated condenser structure. In this embodiment, the air-cooling channel 114 formed between the cover plate 112 and the inner plate 113 is connected to the air supply system 9. Cold air flows in from one end of the air-cooling channel 114, exchanges heat with the side plate 11 of the cylinder 1 to reduce the surface temperature of the cylinder 1, and then flows out from the other end of the air-cooling channel 114. In order to realize the air-cooling and cooling function of the integrated condenser, the combustion system 8 below the integrated condenser structure of the utility model is also provided with an air-cooling air channel 81. When the cold air is driven into by the air supply system, a part of it is used for gas combustion, and the other part enters the air-cooling air channel 81 of the combustion cavity of the combustion system, and then flows into the air-cooling channel 114 of the integrated condenser structure, thereby realizing the integrated air-cooling and cooling effect on the entire system platform.
