Specifically, the partition board 200 is provided with the transverse board 210 and the vertical board 220, so that after the flue gas enters the first cavity 140 from the flue gas inlet channel 121, the flue gas flows upwards in the vertical direction, and exchanges heat with the first section 310, because the first section 310 and the transverse board 210 are arranged at intervals, the flue gas does not flow downwards immediately after flowing through the top of the first section 310, but flows downwards after continuing to flow upwards to the transverse board 210, so that the flue gas can form vortex to flow downwards in a roundabout way, the residence time of the flue gas in the first cavity 140 is increased, the contact times between the flue gas and the first section 310 are increased, and then the heat exchange between the flue gas and the first section 310 is more sufficient, and the heat exchange efficiency is effectively improved.

Optionally, a first preset distance D1 is spaced between the end of the first section 310, which is close to the transverse plate 210, and the transverse plate 210, where D1 is greater than or equal to 10mm and less than or equal to 30mm, and a space is reserved for the flue gas so that the flue gas can exchange heat with the first section 310 sufficiently.

Preferably, the smoke outlet channel 131 is also provided with a smoke outlet tube 132, which is convenient for connecting a smoke outlet pipeline; a smoke discharging sealing ring 133 is arranged between the smoke discharging tube 132 and the smoke discharging channel 131 to avoid the overflow of the smoke.

Alternatively, the cross plate 210 and the riser 220 are disposed vertically, i.e., the riser 220 is disposed vertically with respect to the cover 130. In order to connect the partition board 200 and the housing 100, sliding connection, clamping connection, etc. may be adopted, and those skilled in the art may set the connection according to actual needs, which is not limited herein.

It should be noted that, the transverse plate 210 and the cover 130 are also arranged at intervals, and the interval distance is set to be 3mm-5mm, so as to avoid interference between the partition plate 200 and the cover 130, and the loosening of the transverse plate 210 or the cover 130 is caused, thereby ensuring the reliability of the condenser; and meanwhile, the installation is more convenient.

In one embodiment, the first section 310 includes a first straight pipe section 311 extending in a vertical direction and a first curved pipe section 312, wherein the first straight pipe section 311 is disposed in parallel with a side wall of the housing 100, and the first curved pipe section 312 is used to connect the first curved pipe sections 312 of the two first straight pipe sections 311. It should be noted that, to achieve the connection of the first section 310 and the second section 320, at least a first bend section 312 is present for connecting the first straight section 311 and the second section 320.

Specifically, the first bend section 312 is disposed parallel to the axis of the smoke inlet channel 121, so that, compared with the arrangement of the first bend section 312 and the axis of the smoke inlet channel 121, more first straight tube sections 311 can be disposed in the limited space of the first cavity 140, so that the space of the first cavity 140 is fully utilized, the length of the first section 310 in the first cavity 140 and the contact area of the smoke and the first section 310 are effectively increased, and the heat exchange capability is further improved.

Further, the end of the first section 310 close to the transverse plate 210 is higher than the top wall of the smoke inlet channel 121, i.e. at least part of the first section 310 is higher than the top wall of the smoke inlet channel 121, so that the smoke entering the first cavity 140 through the smoke inlet channel 121 exchanges heat with at least part of the first section 310 when flowing upwards, thereby ensuring the heat exchange effect.

Optionally, the end of the first section 310 near the transverse plate 210 is spaced from the end of the smoke inlet channel 121 near the transverse plate 210 by a second preset distance D2, the diameter of the condensation duct 300 is set to D, the length of the first straight duct section 311 is set to L, D2 is less than or equal to L/2, and it is ensured that the flue gas has enough condensation duct 300 to exchange heat with the flue gas in the space between the end of the smoke inlet channel 121 near the transverse plate 210 and the transverse plate 210.

In this embodiment, a third preset distance D3 is spaced between the two first straight pipe sections 311 that are spaced along the smoke inlet direction of the smoke inlet channel 121, the diameter of the condensation pipe 300 is set to D, D is less than or equal to D3 and less than or equal to d+6mm, it can be understood that the above arrangement ensures that, while the feasibility of processing is ensured, heat exchange can be effectively performed between the two first straight pipe sections 311 and the smoke, and on the other hand, the compactness of the arrangement between the two first straight pipe sections 311 is also ensured, so that more condensation pipes 300 can be arranged in the first cavity 140.

In one embodiment, the second section 320 is disposed at an angle α with respect to the axis of the smoke outlet channel 131, and the second section 320 gradually slopes away from the smoke inlet channel 121 from the direction approaching the smoke outlet channel 131. The second section 320 disposed obliquely is disposed to intersect with the flue gas in the flow direction of the second chamber 150, so that the contact area between the flue gas and the second section 320 can be effectively increased, and the heat exchange capability of the condenser tube 300 can be further improved.

Alternatively, the included angle α is set to 8 ° -15 °, while ensuring that the second section 320 does not collide with the side walls and top wall of the housing 100.

In the prior art, the flow of the flue gas easily impacts the condensation duct 300, so that the condensation duct 300 is loosened, thereby affecting the performance and increasing noise. Therefore, the condenser further comprises a snap spring 400 for clamping the condenser tube 300. It should be noted that the second section 320 disposed obliquely is more susceptible to the impact of the smoke and is loosened. Specifically, in order to realize the clamping connection of the second section 320, an installation protrusion 122 is disposed on an inner wall of one side of the housing 100 away from the smoke inlet channel 121, an installation hole 221 is disposed on the vertical plate 220, the clamp spring 400 is clamped with the second section 320, one end of the clamp spring is abutted with the installation protrusion 122, and the other end of the clamp spring is arranged in the installation hole 221 in a penetrating manner. The clamping spring 400 is more firmly clamped, so that the shaking of the condenser tube 300 along the axial direction can be effectively avoided, and the reliability of assembly and the reliability of the condenser are improved. Illustratively, the diameter of the mounting hole 221 is slightly larger than 0.2mm-0.3mm of the diameter of the clamp spring 400, so that the stable assembly is ensured, and meanwhile, the flue gas can effectively overflow from the mounting hole 221.

The embodiment also discloses a gas water heater, which comprises the condenser according to any one of the schemes. The flue gas enters the heat exchange cavity 110 from the flue gas inlet channel 121, exchanges heat with the first section 310 of the condensation pipe 300 in the first cavity 140, exchanges heat with the second section 320 of the condensation pipe 300 in the second cavity 150, and finally flows out of the heat exchange cavity 110 from the flue gas outlet channel 131. The flue gas flowing through the gas water heater provided with the condenser has longer residence time in the heat exchange cavity 110, especially the first cavity 140, so that the heat exchange of the gas water heater is more sufficient, and the heat exchange efficiency is higher.

In the specific content of the above embodiment, any combination of the technical features may be performed without contradiction, and for brevity of description, all possible combinations of the technical features are not described, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
