The tank body 10 comprises a second side plate 14, and the tank body 10 further comprises a first side plate 13. The second side plate 14 and the first side plate 13 are oppositely arranged in a first direction of the water tank assembly 100.

The first side plate 13 is arranged as an integral molding, and the second side plate 14 is arranged as an integral molding, that is, the first side plate 13 and the second side plate 14 are both arranged as integral moldings. This arrangement facilitates the production of the second side plate 14 and the first side plate 13, improves the production efficiency of the second side plate 14 and the first side plate 13, thereby improving the production efficiency of the water tank assembly 100, and also reduces the number of molds for developing and producing the tank body 10, reduces the production cost of the tank body 10, thereby reducing the production cost of the water tank assembly 100.

[0046] Further, as shown in Figure 2 and Figure 3 , the first side plate 13 is provided with a first water box 131, and the first water box 131 is arranged in multiple, and the second side plate 14 is provided with a second water box 141, and the second water box 141 is arranged in multiple, and the first side plate 13 is provided with a water outlet 133 and a water inlet 132, the water inlet 132 is communicated with one of the multiple first water boxes 131, and the water outlet 133 is communicated with one of the multiple first water boxes 131, further, as shown in Figure 2 , in the up-down direction of Figure 2 , the arrangement height of part of the multiple first water boxes 131 is the same, the arrangement height of part of the multiple first water boxes 131 is different, and the arrangement height of the water outlet 133 is higher than the arrangement height of the water inlet 132, that is, the water outlet 133 is arranged above the water inlet 132, as shown in Figure 3 , in the up-down direction of Figure 3 , the arrangement height of part of the multiple second water boxes 141 is the same, and the arrangement height of part of the multiple second water boxes 141 is different.

[0047] The condenser pipe assembly 30 is located on the side of the main heat exchange pipe assembly 20 facing the smoke outlet 12, which can also be understood as, in the up-down direction of Figure 2 , the main heat exchange pipe assembly 20 is arranged on the upper side of the condenser pipe assembly 30, and the multiple second water boxes 141 and the multiple first water boxes 131 are communicated through the condenser pipe assembly 30 and the main heat exchange pipe assembly 20, wherein the main heat exchange pipe assembly 20 includes a first heat exchange pipe 21, and the first heat exchange pipe 21 is arranged in multiple, and the condenser pipe assembly 30 includes a second heat exchange pipe 31, and the second heat exchange pipe 31 is arranged in multiple, and the multiple first heat exchange pipes 21 are arranged in multiple layers, and the multiple layers of first heat exchange pipes 21 are arranged in the direction from the smoke inlet 11 to the smoke outlet 12, which means Figure 2The first layer of heat exchange pipes 22 is the layer closest to the smoke inlet 11 in the up-down direction, and the first layer of heat exchange pipes 22 is in communication with the corresponding first water box 131 and the corresponding second water box 141 to form a series water circuit. One end of the first layer of heat exchange pipes 22 is in communication with the corresponding first water box 131, and the other end of the first layer of heat exchange pipes 22 is in communication with the corresponding second water box 141. Cold water can flow into the first water box 131 from the water inlet 132, flow through the second heat exchange pipe 31, and then flow through the first water box 131 and the second water box 141 on both sides layer by layer upwards, and then flow through the first heat exchange pipe 21, and finally hot water flows out of the water outlet 133.

[0048] In the application, since the first layer of heat exchange pipes 22 is in communication with the corresponding first water box 131 and the corresponding second water box 141 to form a series water circuit, that is, the high-temperature heat exchange section water circuit structure adopts a series scheme, that is, the water circuit in the water tank assembly 100 is in series as a water circuit, and there is no uneven distribution of water flow and water flow speed inside the water circuit. Compared with the prior art, the water flow or water flow speed in the main heat exchange pipe assembly 20 and the condenser pipe assembly 30 can be more uniform, which can slow down the water vaporization and scaling in the condenser pipe assembly 30 and the main heat exchange pipe assembly 20, reduce the risk of damage to the first heat exchange pipe 21 and the second heat exchange pipe 31, and prolong the service life of the water tank assembly 100 and the heating equipment 200.

[0049] Further, at least a part of the first heat exchange pipe 21 and / or at least a part of the second heat exchange pipe 31 is arranged on the heat exchange fin assembly 40, that is, at least a part of the plurality of first heat exchange pipes 21 can be arranged on the heat exchange fin assembly 40, at least a part of the plurality of second heat exchange pipes 31 can be arranged on the heat exchange fin assembly 40, or the first heat exchange pipe 21 and the second heat exchange pipe 31 can be arranged on the heat exchange fin assembly 40. The heat exchange fin assembly 40 can be arranged in the box 10. After the high-temperature flue gas burned by the burner flows into the box 10 from the smoke inlet 11, the high-temperature flue gas can transfer heat to the first heat exchange pipe 21 and / or the second heat exchange pipe 31. Such an arrangement can transfer more heat to the cold water in the first heat exchange pipe 21 and / or the second heat exchange pipe 31, improve the heat exchange efficiency, and thus make the cold water become hot water more quickly, thereby improving the heat exchange efficiency of the water tank assembly 100 and the working performance of the heating equipment 200.

[0050] Thus, by the first layer heat exchange pipe 22 being communicated with the first water box 131 and the second water box 141 to form a series water path, compared with the prior art, the water flow or water flow rate in the condensing pipe assembly 30 and the main heat exchange pipe assembly 20 can be more uniform, the water vaporization and scaling in the condensing pipe assembly 30 and the main heat exchange pipe assembly 20 can be slowed down, the damage risk of the first heat exchange pipe 21 and the second heat exchange pipe 31 can be reduced, and the service life of the water tank assembly 100 and the heating equipment 200 can be prolonged.

[0051] In some embodiments of the present application, as shown in Figure 2 The tank body 10 can further include a second heat insulation plate 60 and a first heat insulation plate 50, the second heat insulation plate 60 and the first heat insulation plate 50 are oppositely arranged, the first heat insulation plate 50 is connected with the second side plate 14 and the first side plate 13 respectively, the second heat insulation plate 60 is connected with the second side plate 14 and the first side plate 13 respectively, and further, as shown in Figure 2 The left end of the first heat insulation plate 50 is connected with the first side plate 13, the right end of the first heat insulation plate 50 is connected with the second side plate 14, the left end of the second heat insulation plate 60 is connected with the first side plate 13, and the right end of the second heat insulation plate 60 is connected with the second side plate 14, wherein the second heat insulation plate 60 and the first heat insulation plate 50 have a heat insulation effect, after the high-temperature flue gas combusted by the burner flows into the tank body 10 from the smoke inlet 11, the heat can be prevented from being transferred from the second heat insulation plate 60 and the first heat insulation plate 50 to the outside of the tank body 10, the heat can be prevented from being dissipated from the second heat insulation plate 60 and the first heat insulation plate 50, so that the heat exchange efficiency of the water tank assembly 100 can be ensured, and further, the heating efficiency of the heating equipment 200 can be ensured.

[0052] Further, the second heat insulation plate 60 and the first heat insulation plate 50 can be respectively arranged as an integral molding, the integral molding has high structural strength, such an arrangement can improve the structural strength of the second heat insulation plate 60 and the first heat insulation plate 50, can avoid the deformation of the tank body 10, and also can facilitate the production and manufacturing of the second heat insulation plate 60 and the first heat insulation plate 50, can improve the production efficiency of the second heat insulation plate 60 and the first heat insulation plate 50, so that the production efficiency of the water tank assembly 100 can be further improved, and also can reduce the number of molds for developing and producing the tank body 10, can further reduce the production cost of the tank body 10, so that the production cost of the water tank assembly 100 can be reduced.

[0053] In some embodiments of the present application, as shown in Figure 4 The tank body 10 can further include a smoke baffle 70, the smoke baffle 70 can be arranged as an integral type, i.e. the smoke baffle 70 is arranged as an integral molding, the smoke baffle 70 is connected with the second side plate 14, the first side plate 13, the second heat insulation plate 60 and the first heat insulation plate 50 respectively, and the smoke outlet 12 can be arranged on the smoke baffle 70. Wherein, as shown in Figure 4As shown, the smoke baffle 70 is connected with the lower end of the second side plate 14, the lower end of the first side plate 13, the lower end of the second heat insulation plate 60 and the lower end of the first heat insulation plate 50 respectively. After the high-temperature flue gas burned by the burner flows into the box body 10 from the smoke inlet 11, when the flue gas flows to the smoke baffle 70, the smoke baffle 70 has a blocking effect on the flue gas, which can slow down the time of the flue gas flowing out of the smoke outlet 12, and can prolong the residence time of the flue gas in the box body 10, thereby increasing the heat exchange time of the high-temperature flue gas with the first heat exchange pipe 21, the second heat exchange pipe 31 and the heat exchange fin assembly 40, and further more heat can be used to heat the cold water, which reduces the heat loss and improves the heating efficiency of the heating equipment 200.

[0054] In some embodiments of the present application, as shown in Figure 4 As shown, the smoke outlet 12 can include a plurality of through holes, and the plurality of through holes can be arranged in a long strip shape and uniformly spaced. Such an arrangement can ensure the flow area of the flue gas, and can ensure that the flue gas flows smoothly out of the box body 10 from the smoke outlet 12, thereby avoiding the explosion of the box body 10 due to excessive pressure in the box body 10, and further improving the use safety of the heating equipment 200. However, the present application is not limited thereto, and the smoke outlet 12 can include a plurality of through holes, and the shape of the through holes can be circular, oval, trapezoidal or other shapes, as long as the shape of the through hole has the same effect as the long strip shape.

[0055] In some embodiments of the present application, the same side of the plurality of first water boxes 131 is open, and the same side of the plurality of second water boxes 141 is open. Further, the side of the plurality of first water boxes 131 facing the inside of the box body 10 is open, and the side of the plurality of second water boxes 141 facing the inside of the box body 10 is open. As shown in Figure 2 The side of the plurality of first water boxes 131 facing the inside of the box body 10 is open, and the side of the plurality of second water boxes 141 facing the inside of the box body 10 is open. The box body 10 can further include a second bottom plate 16, and the box body 10 can further include a first bottom plate 15. The first bottom plate 15 and the second bottom plate 16 can be arranged as an integral molded part. The first bottom plate 15 and the first side plate 13 can cover the open side of the plurality of first water boxes 131, and the second bottom plate 16 and the second side plate 14 can cover the open side of the plurality of second water boxes 141.

[0056] Further, the first bottom plate 15 can be provided with a plurality of first bottom plates 15 corresponding to a plurality of first water boxes 131, and the second bottom plate 16 can be provided with a plurality of second bottom plates 16 corresponding to a plurality of second water boxes 141. The plurality of first bottom plates 15 and the plurality of second bottom plates 16 are provided with mounting holes penetrating through the corresponding first bottom plate 15 and second bottom plate 16, and the first heat exchange pipe 21 and the second heat exchange pipe 31 are installed in the corresponding mounting holes. In this way, the water in the first water box 131 can flow into the first heat exchange pipe 21 and the second heat exchange pipe 31, and the water in the second water box 141 can also flow into the first heat exchange pipe 21 and the second heat exchange pipe 31. This can prevent water from flowing out of the open side of the first water box 131 and the open side of the second water box 141, thereby preventing the water tank assembly 100 from leaking.

[0057] Of course, the first bottom plate 15 can be provided as an integrally formed plate structure, and one first bottom plate 15 can simultaneously cover the open side of a plurality of first water boxes 131. The second bottom plate 16 can also be provided as an integrally formed plate structure, and one second bottom plate 16 can simultaneously cover the open side of a plurality of second water boxes 141.

[0058] In some embodiments of the present application, as shown in Figure 6 Further, the cross section of the second heat exchange pipe 31 is elliptical, and the cross section of the second heat exchange pipe 31 is also elliptical. If the water flow speed in the second heat exchange pipe 31 is too low and the resistance is too large, the water in the second heat exchange pipe 31 is prone to vaporization, or scale is formed in the second heat exchange pipe 31, thereby affecting the performance and service life of the heating device 200. Therefore, by setting the cross section of the second heat exchange pipe 31 to be elliptical, the flow resistance of the water in the second heat exchange pipe 31 can be reduced, and the deposition of insoluble substances in the second heat exchange pipe 31 can be prevented, thereby preventing the water in the second heat exchange pipe 31 from vaporizing and slowing down the formation of scale in the second heat exchange pipe 31, thereby prolonging the performance and service life of the heating device 200. However, the present application is not limited thereto, and the cross section of the second heat exchange pipe 31 can be set to other irregular shapes as long as it has the same effect as the elliptical shape.

[0059] In some embodiments of the present application, as shown in Figure 6As shown, the cross section of at least part of the plurality of first heat exchange pipes 21 is elliptical. If the water flow speed in the first heat exchange pipe 21 is too low, the resistance is too large, the water is easy to vaporize in the first heat exchange pipe 21, or scale is formed in the first heat exchange pipe 21, thereby affecting the use performance and service life of the heating device 200. Therefore, by setting the cross section shape of at least part of the first heat exchange pipe 21 to be elliptical, the water flow resistance in the first heat exchange pipe 21 can be reduced when the water flows in the first heat exchange pipe 21, the insoluble substances can be prevented from depositing in the first heat exchange pipe 21, thereby preventing the water from vaporizing in the first heat exchange pipe 21, and slowing down the formation of scale in the first heat exchange pipe 21, and further prolonging the use performance and service life of the heating device 200. However, the present application is not limited thereto, and the cross section shape of the first heat exchange pipe 21 can be set to other irregular shapes, as long as the cross section shape of the first heat exchange pipe 21 has the same effect as the elliptical shape.

[0060] In some embodiments of the present application, as shown in Figure 6 As shown, the plurality of first heat exchange pipes 21 are arranged in two layers, and the two layers of first heat exchange pipes 21 are arranged in the direction from the smoke inlet 11 to the smoke outlet 12. Part of the plurality of first heat exchange pipes 21 in the first layer of heat exchange pipes 22 has an elliptical cross section, and another part of the plurality of first heat exchange pipes 21 in the first layer of heat exchange pipes 22 has a circular cross section. The second layer of heat exchange pipes is arranged below the first layer of heat exchange pipes 22, and the cross section of each first heat exchange pipe 21 in the second layer of heat exchange pipes is elliptical. When the water flows in the plurality of first heat exchange pipes 21, the water flow resistance in the first heat exchange pipe 21 can be further reduced, the insoluble substances can be further prevented from depositing in the first heat exchange pipe 21, thereby further preventing the water from vaporizing in the first heat exchange pipe 21, and further slowing down the formation of scale in the first heat exchange pipe 21, and further prolonging the use performance and service life of the heating device 200.

[0061] In some embodiments of the present application, a disturbance member can be arranged on the heat exchange fin assembly 40, and the disturbance member is used to change the flow direction of the flue gas in the box body 10.

Such an arrangement can realize the technical solution of arranging the first heat exchange pipe 21 in the first fin, prevent the first fin from separating from the first heat exchange pipe 21, and thus ensure that the first heat exchange pipe 21 and the first fin can exchange heat. Further, by arranging a plurality of first fins, the heat exchange efficiency of the heat exchange fin assembly 40 and the first heat exchange pipe 21 can be improved.

[0064] In some embodiments of the present application, as shown in Figure 7 and Figure 8 , the first fin includes a first sub-fin 43 and a second sub-fin 44. The first sub-fin 43 can be arranged outside the first heat exchange pipe 21. The second sub-fin 44 can also be arranged outside the first heat exchange pipe 21, and the second sub-fin 44 is arranged on the side wall of the tank body 10, for example, the second sub-fin 44 is arranged on the inner surface of the first heat insulation plate 50. Such an arrangement can increase the heat exchange area of the heat exchange fin assembly 40.

[0065] In some embodiments of the present application, the manufacturing material of the water tank assembly 100 can be stainless steel. Such an arrangement can effectively improve the corrosion resistance of the water tank assembly 100, and further prolong the service life of the water tank assembly 100.
