[0030] The utility model will be further illustrated by the embodiment, but not therefore limit the utility model in the embodiment range.
[0031] The utility model embodiment provides a kind of side plate 10 of heat exchanger 1, as Figure 1 、 Figure 2 、 Figure 3 And Figure 4 Indicated, heat exchanger 1 has heat exchange space 40 in it, gas 2 flows through heat exchange space 40 to carry out heat exchange. Specifically, heat exchanger 1 includes fin 20 and heat exchange pipe 30, fin 20 is sleeved in heat exchange pipe 30, heat exchange pipe 30 is used to flow through fluid, when gas 2 flows through heat exchange space 40, can be exchanged with fluid heat. In gas water heater, cold water enters heat exchange pipe 30, is heated by high-temperature flue gas gas 2, and becomes hot water from cold water, then flows out heat exchanger 1. Among them, heat exchange space 40 refers to the space part for heat exchange in heat exchanger 1, for the heat exchanger 1 with fin 20 and heat exchange pipe 30 described above, it is the space formed by the above fin 20 and heat exchange pipe 30. Heat exchange space 40 has side plate 10 on both sides, and the side plate 10 is as the edge plate of heat exchange space 40, the space between two side plates 10 accommodates fin 20 and heat exchange pipe 30, and as heat exchange space 40.
[0032] As Figure 1 、 Figure 2 、 Figure 3 And Figure 4As shown, the side plate 10 comprises a plate body 11 and an extension 12, the plate body 11 is arranged at one side of the heat exchange space 40, and the extension 12 is connected with the plate body 11 and located at a position of the plate body 11 close to the gas inlet side of the gas 2 and extends into the heat exchange space 40.
[0033] Specifically, the plate body 11 is a substantially flat plate structure, which forms the main structural part of the side of the heat exchange space 40. A plurality of heat exchange pipes 30 are arranged side by side, and a plurality of fins 20 are sleeved outside the heat exchange pipes 30 and are arranged in sequence along the axis direction of the heat exchange pipes 30. There is a spacing between the inner surface of the plate body 11 and the fin 20 at the endmost part. When the extension 12 is not arranged, the gas 2 will enter between the plate body 11 and the fin 20, which will affect the heating of the fin 20 and also cause unnecessary heating of the plate body 11. By arranging the extension 12 on the plate body 11 and extending the extension 12 into the heat exchange space 40, the gas 2 can be gathered inward, so that the gas 2 enters the heat exchange space 40 more, and at the same time, the heating of the side plate 10 by the gas 2 can be reduced. Therefore, not only the heat exchange effect can be improved, but also the parts can be saved and the cost can be reduced.
[0034] Further, as shown in the drawings, Figure 2 In the gas water heater, the gas 2 generally flows from bottom to top, and the position of the plate body 11 close to the gas inlet side of the gas 2 is the lower region thereof. The extension 12 is located at the lower region of the plate body 11 and below the fin 20.
[0035] As shown in the drawings, Figure 2 The heat exchange space 40 has a plurality of fins 20, and the plate body 11 is located at one side of the fin 20 at the endmost part in the heat exchange space 40 and has a first spacing 50 with the fin 20; the extension length of the extension 12 into the heat exchange space 40 is related to the first spacing 50. The first spacing 50 is between the fin 20 at the endmost part and the inner surface of the plate body 11 along the axis direction of the heat exchange pipe 30; by associating the extension length of the extension 12 with the first spacing 50, the space between the plate body 11 and the fin 20 into which the gas 2 enters can be controlled. On the one hand, it can avoid that the extension 12 is too long and affects the heat exchange of the gas 2 with the fin 20 at the side region of the heat exchange space 40, and on the other hand, it can also block the gas 2 from entering the space between the fin 20 and the plate body 11, causing unnecessary heat exchange.
[0036] As shown in the drawings, Figure 2 The extension length of the extension 12 into the heat exchange space 40 is not less than the first spacing 50. The gas 2 flows from bottom to top, and the extension 12 extends along the horizontal direction, and the extension length thereof in the horizontal direction is not less than the first spacing 50.
[0037] Specifically, the extension length of the extension part 12 ranges from 2mm to 10mm. Preferably, the extension length of the extension part 12 is 3mm. In other embodiments, the extension length of the extension part 12 can also have other values according to the first spacing 50 between the plate body 11 and the fin 20, so as to reduce or avoid the gas 2 entering the space between the plate body 11 and the fin 20.
[0038] Specifically, the extension part 12 is integrally formed with the plate body 11. Thus, the cost can be further reduced.
[0039] As a specific embodiment of the extension part 12, as shown in Figure 3 and Figure 4 , the extension part 12 is a first flange 13 arranged at the edge of the plate body 11.
[0040] As shown in Figure 3 and Figure 4 , both sides of the plate body 11 along the gas inlet direction of the gas 2 are provided with a second flange 14 extending into the heat exchange space 40.
[0041] The utility model embodiment further provides a heat exchanger 1, as shown in Figure 1 and Figure 2 , both sides of the heat exchange space 40 of the heat exchanger 1 are provided with the side plate 10, and at least one of the two side plates 10 is the side plate 10 of the heat exchanger 1 as described above. The heat exchanger 1 can gather the gas 2 to the inside by adopting the above-mentioned side plate 10, so that the gas 2 enters the heat exchange space 40 more, and also can reduce the temperature rise of the gas 2 to the side plate 10. Thus, not only the heat exchange effect can be improved, but also the parts can be saved and the cost can be reduced.
[0042] As shown in Figure 2 , the side plates 10 on both sides of the heat exchanger 1 are both the side plates 10 with the extension part 12. Specifically, the first spacing 50 is arranged between the fin 20 at the end of the heat exchanger 1 and the corresponding side plate 10, and the extension length of the extension part 12 of the two side plates 10 is not less than the first spacing 50. Further, the first spacing 50 between the two fins 20 and the corresponding side plate 10 can be the same or different, and correspondingly, the extension length of the extension part 12 of the two side plates 10 can be the same or different.
