[0044] The following will be described with reference to Figures 1-9 The heating device 200 according to the embodiments of the present application is described below, the heating device 200 comprises the water tank assembly 100, and the heating device 200 can be provided as a water heater or a wall-mounted boiler.

[0045] As Figures 1-9As shown, the water tank assembly 100 according to an embodiment of the present invention includes: a tank body 10, a main heat exchange tube assembly 20, a heat exchange fin assembly 40, and a condenser tube assembly 30. The tank body 10 has a flue gas outlet 12 and a flue gas inlet 11. The heating device 200 may be equipped with a burner. High-temperature flue gas burned by the burner can flow into the tank body 10 from the flue gas inlet 11, and high-temperature flue gas in the tank body 10 can flow out of the tank body 10 from the flue gas outlet 12. The tank body 10 includes a first side plate assembly 17 and a second side plate assembly 18. The second side plate assembly 18 and the first side plate assembly 17 are arranged opposite to each other. Further, the second side plate assembly 18 and the first side plate assembly 17 are arranged opposite to each other in a first direction of the water tank assembly 100. The first direction of the water tank assembly 100 can refer to... Figure 2 The second side panel assembly 18 and the first side panel assembly 17 are spaced apart in the first direction of the water tank assembly 100. The first side panel assembly 17 defines a first water box 131, and there are multiple first water boxes 131. The second side panel assembly 18 defines a second water box 141, and there are multiple second water boxes 141.

[0046] The first side panel assembly 17 is provided with a water outlet 133 and a water inlet 132. The water inlet 132 is connected to one of the multiple first water boxes 131, and the water outlet 133 is connected to one of the multiple first water boxes 131. Further, as Figure 2 As shown, in Figure 2 In the vertical direction, some of the multiple first water boxes 131 are set at the same height, while others are set at different heights. The outlet 133 is set at a higher height than the inlet 132, meaning the outlet 133 is located above the inlet 132. Figure 3 As shown, in Figure 3 In the vertical direction, some of the multiple second water boxes 141 are set at the same height, while some of the multiple second water boxes 141 are set at different heights.

[0047] Furthermore, the second side panel assembly 18 may include a second side panel 14, and the first side panel assembly 17 may include a first side panel 13. Both the second side panel 14 and the first side panel 13 may be integrally molded parts. The second side panel 14 is integrally molded part, that is, both the first side panel 13 and the second side panel 14 are integrally molded parts. This arrangement facilitates the production and manufacturing of the second side panel 14 and the first side panel 13, improves the production efficiency of the second side panel 14 and the first side panel 13, thereby improving the production efficiency of the water tank assembly 100. In addition, it can also reduce the number of molds for developing and producing the tank body 10, thereby reducing the production cost of the tank body 10 and thus reducing the production cost of the water tank assembly 100.

[0048] Further, as shown in Figure 2 The first side plate 13 can be defined with a first water box 131, and the second side plate 14 can be defined with a second water box 141. The first side plate 13 is provided with a water outlet 133 and a water inlet 132.

[0049] The condenser pipe assembly 30 is located on the side of the main heat exchange pipe assembly 20 facing the smoke outlet 12. It can also be understood that, in the up-down direction in Figure 2 The main heat exchange pipe assembly 20 is arranged on the upper side of the condenser pipe assembly 30, and the plurality of second water boxes 141 and the plurality of first water boxes 131 are communicated through the condenser pipe assembly 30 and the main heat exchange pipe assembly 20. 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. The condenser pipe assembly 30 includes a second heat exchange pipe 31, and the second heat exchange pipe 31 is arranged in multiple. Every two first heat exchange pipes 21 form a reciprocating heat exchange group, and multiple first heat exchange pipes 21 can form multiple reciprocating heat exchange groups. Each reciprocating heat exchange group is communicated with one of the plurality of first water boxes 131 and two second water boxes 141, so as to form a series water circuit. It should be noted that one end of the first heat exchange pipe 21 in the reciprocating heat exchange group is communicated with one first water box 131, and the other end of the first heat exchange pipe 21 is communicated with one second water box 141. One end of the second heat exchange pipe 21 in the reciprocating heat exchange group is communicated with another second water box 141, and the second water box 141 communicated with the first heat exchange pipe 21 is communicated with the second water box 141 communicated with the second heat exchange pipe 21. After the water flows into the first heat exchange pipe 21 from the first water box 131, the water can flow into the second water box 141 communicated with the first heat exchange pipe 21, and then the water flows into another second water box 141 from the second water box 141 communicated with the first heat exchange pipe 21, and then the water flows into the second heat exchange pipe 21. The cross section of each first heat exchange pipe 21 is formed in a long strip structure, and no spoiler is arranged in each first heat exchange pipe. The 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 upward, then flow through the first heat exchange pipe 21, and finally the hot water flows out of the water outlet 133.

[0050] The high-temperature flue gas combusted by the burner flows into the box 10 from the smoke inlet 11, and then the high-temperature flue gas in the box 10 first flows through the main heat exchange pipe assembly 20, the high-temperature flue gas transmits heat to the cold water in the first heat exchange pipe 21, the cold water in the first heat exchange pipe 21 absorbs heat to become hot water, and then the flue gas passing through the main heat exchange pipe assembly 20 flows through the second heat exchange pipe 31 of the condensing pipe assembly 30, the cold water in the second heat exchange pipe 31 absorbs heat to become hot water, the flue gas exchanges heat with the condensing pipe assembly 30 and produces condensed water which is discharged from the smoke outlet 12. In this application, each group of reciprocating heat exchange assemblies is in communication with one of the first water boxes 131 and two second water boxes 141 to form a series water path, that is, the high-temperature heat exchange section water path structure adopts a series scheme, that is, the water path in the water tank assembly 100 is in series to form a water path, and there is no uneven distribution of water flow and water flow speed in the water path. Compared with the prior art, the water flow or water flow speed in the main heat exchange pipe assembly 20 and the condensing pipe assembly 30 is more uniform, which can slow down the water vaporization and scaling in the condensing 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.

[0051] If the water flow speed in the first heat exchange pipe 21 is too low and the resistance is too large, the water is easy to vaporize in the first heat exchange pipe 21, or scaling is formed in the first heat exchange pipe 21, thereby affecting the use performance and service life of the heating equipment 200. Therefore, by setting the cross section of each first heat exchange pipe 21 as a long strip structure and not setting a spoiler in each first heat exchange pipe, the water flow resistance in the first heat exchange pipe 21 can be effectively reduced when the water flows in the first heat exchange pipe 21, which can further prevent insoluble substances from depositing in the first heat exchange pipe 21, thereby further preventing water vaporization in the first heat exchange pipe 21 and further slowing down the formation of scaling in the first heat exchange pipe 21, further avoiding the blockage of the first heat exchange pipe 21 and the second heat exchange pipe 31, thereby further preventing the heating equipment 200 from dry burning and cracking, and further prolonging the use performance and service life of the heating equipment 200.

[0052] Further, at least part of the first heat exchange pipes 21 and / or at least part of the second heat exchange pipes 31 are arranged on the heat exchange fin assembly 40, that is, at least part of the plurality of first heat exchange pipes 21 can be arranged on the heat exchange fin assembly 40, at least 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 pipes 21 and the second heat exchange pipes 31 can be arranged on the heat exchange fin assembly 40. The heat exchange fin assembly 40 can be arranged in the box body 10. After the high-temperature flue gas burned by the burner flows into the box body 10 from the flue gas inlet 11, the high-temperature flue gas can transfer heat to the first heat exchange pipes 21 and / or the second heat exchange pipes 31 through the heat exchange fin assembly 40. Such an arrangement can transfer more heat to the cold water in the first heat exchange pipes 21 and / or the second heat exchange pipes 31, improve the heat exchange efficiency, and thus can 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.

[0053] Thus, compared with the prior art, by arranging each group of reciprocating heat exchange groups in communication with one first water box 131 and two second water boxes 141 to form a series water circuit, and forming each first heat exchange pipe 21 in a long strip shape and not arranging a spoiler in each first heat exchange pipe 21, the water flow or water flow rate in the main heat exchange pipe assembly 20 and the condenser pipe assembly 30 can be uniform, water vaporization and scaling in the main heat exchange pipe assembly 20 and the condenser pipe assembly 30 can be slowed down, water flow resistance in the first heat exchange pipe 21 can be slowed down, and the first heat exchange pipe 21 and the second heat exchange pipe 31 can be prevented from being blocked, thereby preventing the heating equipment 200 from dry burning and cracking, and prolonging the service life of the water tank assembly 100 and the heating equipment 200.

After the high-temperature flue gas burned by the burner flows into the box body 10 from the flue gas inlet 11, the high-temperature flue gas can transfer heat to the heat exchange fin assembly 40, and then the heat exchange fin assembly 40 can transfer heat to the first heat exchange pipes 21 and the second heat exchange pipes 31. Such an arrangement can transfer more heat to the cold water in the first heat exchange pipes 21 and / or the second heat exchange pipes 31, improve the heat exchange efficiency, and thus can 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.

[0055] In some embodiments of the present application, the plurality of first heat exchange pipes 21 can be arranged in multiple layers, the multiple layers of first heat exchange pipes 21 are arranged in a direction from the smoke inlet 11 to the smoke outlet 12, the direction from the smoke inlet 11 to the smoke outlet 12 refers to the up-down direction in Figure 2 , the first layer of heat exchange pipes is the layer closest to the smoke inlet 11, the first layer of heat exchange pipes in communication with the corresponding first water box 131 and the corresponding second water box 141 can form a series water circuit, one end of the first layer of heat exchange pipes is in communication with the corresponding first water box 131, and the other end of the first layer of heat exchange pipes is in communication with the corresponding second water box 141.

[0056] In some embodiments of the present application, as shown in Figure 2 and Figure 6 , each first water box 131 in communication with the condenser pipe assembly 30 is in communication with at least three second heat exchange pipes 31, such an arrangement can make the water in the first water box 131 flow rapidly into the plurality of second heat exchange pipes 31, and can also make the water in the plurality of second heat exchange pipes 31 flow into the first water box 131 at the same time, which can reduce the water flow time in the condenser pipe assembly 30, avoid water vaporization or fouling in the condenser pipe assembly 30, and also can slow down the water flow resistance in the second heat exchange pipe 31, avoid the second heat exchange pipe 31 being blocked, thereby further preventing the heating equipment 200 from dry burning and cracking, and further prolonging the service life of the water tank assembly 100 and the heating equipment 200.

[0057] In some embodiments of the present application, as shown in Figure 6 , each second heat exchange pipe 31 is formed as a circular pipe, that is, the cross-sectional shape of each second heat exchange pipe 31 is circular, and the plurality of second heat exchange pipes 31 corresponding to each first water box 131 are arranged in multiple rows and multiple columns, such an arrangement can make the structure of the plurality of second heat exchange pipes 31 more compact, and can reduce the volume of the water tank assembly 100, thereby reducing the volume of the heating equipment 200.

As Figure 5 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 in cooperation, 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, so that the residence time of the flue gas in the box body 10 can be prolonged, thereby 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 can be increased, and then more heat can be used to heat the cold water, the heat dissipation is reduced, and the heating efficiency of the heating equipment 200 is improved.

[0064] In some embodiments of the present application, as shown in Figure 5 The smoke baffle 70 can include a plurality of guide plates 71 facing away from the smoke inlet 11, and the smoke outlet 12 includes a first passage 121, and the ends of the plurality of guide plates 71 facing away from the smoke inlet 11 are spaced apart to define the first passage 121. The smoke in the box 10 can flow out of the box 10 through the first passage 121. Such an arrangement can ensure the flow area of the smoke, and can ensure that the smoke flows smoothly out of the box 10 through the smoke outlet 12, thereby avoiding the box 10 from being damaged due to excessive pressure, and further avoiding the explosion of the box 10, and further improving the use safety of the heating device 200.

[0065] In some embodiments of the present application, as shown in Figure 5 The smoke outlet 12 can further include a second passage 122, and each guide plate 71 can be provided with a plurality of second passages 122. The second passage 122 penetrates the guide plate 71 in the thickness direction of the guide plate 71, and the smoke in the box 10 can flow out of the box 10 through the second passage 122. Such an arrangement can increase the flow area of the smoke, and the smoke in the box 10 can flow out of the box 10 through the first passage 121 and the second passage 122 at the same time, which can further ensure that the smoke flows smoothly out of the box 10 through the smoke outlet 12, thereby further avoiding the box 10 from being damaged due to excessive pressure, and further avoiding the explosion of the box 10, and further improving the use safety of the heating device 200.

[0066] In some embodiments of the present application, as shown in Figure 7 The smoke outlet 12 can include a plurality of second through holes, and the plurality of second through holes can be arranged in a long strip shape and uniformly spaced apart. Such an arrangement can ensure the flow area of the smoke, and can ensure that the smoke flows smoothly out of the box 10 through the smoke outlet 12, thereby avoiding the box 10 from being damaged due to excessive pressure, and further avoiding the explosion of the box 10, and further improving the use safety of the heating device 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, etc. The shape of the through holes can only have the same effect as the long strip shape.

[0067] 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 box 10 is open, and the side of the plurality of second water boxes 141 facing the box 10 is open, as shown in Figure 2As shown, the right side of the plurality of first water boxes 131 is open, and the left side of the plurality of second water boxes 141 is open. The second side plate assembly 18 can further include a second bottom plate 16, and the first side plate assembly 17 can further include a first bottom plate 15. The first bottom plate 15 and the first side plate 13 can cooperate to 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 cooperate to cover the open side of the plurality of second water boxes 141.

[0068] Further, the first bottom plate 15 can be provided with a plurality of first bottom plates 15, which are arranged one-to-one with the plurality of first water boxes 131. The second bottom plate 16 can be provided with a plurality of second bottom plates 16, which are arranged one-to-one with the plurality of second water boxes 141. The plurality of first bottom plates 15 and the plurality of second bottom plates 16 are each provided with a mounting hole that penetrates the corresponding first bottom plate 15 or second bottom plate 16. The first heat exchange pipe 21 and the second heat exchange pipe 31 are installed in the corresponding mounting hole. This arrangement can ensure that the water in the first water box 131 flows into the first heat exchange pipe 21 and the second heat exchange pipe 31, and that the water in the second water box 141 flows 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.

[0069] Of course, the first bottom plate 15 can be provided as an integrally formed plate structure, and one first bottom plate 15 can cover the open side of the plurality of first water boxes 131. The second bottom plate 16 can be provided as an integrally formed plate structure, and one second bottom plate 16 can cover the open side of the plurality of second water boxes 141.

[0070] In some embodiments of the present application, the cross section of the second heat exchange pipe 31 can be elliptical. Further, the cross section of the second heat exchange pipe 31 is elliptical. If the water flow speed in the second heat exchange pipe 31 is too low and the resistance is too great, 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 when the water flows in the second heat exchange pipe 31. This can prevent insoluble substances from depositing in the second heat exchange pipe 31, 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, and further 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 an ellipse.

[0071] In some embodiments of the present application, as shown in Figure 6 In some embodiments of the present application, at least a part of the cross sections of the plurality of first heat exchange tubes 21 are elliptical. If the water flow speed in the first heat exchange tubes 21 is too low, the resistance is too large, the water is prone to vaporization in the first heat exchange tubes 21, or scale is formed in the first heat exchange tubes 21, thereby affecting the service performance and service life of the heating device 200. Therefore, by setting the cross section shape of at least a part of the first heat exchange tubes 21 to be elliptical, the water flow resistance in the first heat exchange tubes 21 can be reduced when the water flows in the first heat exchange tubes 21, the insoluble substances can be prevented from depositing in the first heat exchange tubes 21, thereby preventing the water from vaporizing in the first heat exchange tubes 21, slowing down the formation of scale in the first heat exchange tubes 21, and further prolonging the service 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 tubes 21 can be set to other irregular shapes, as long as the cross section shape of the first heat exchange tubes 21 has the same effect as the elliptical shape.

[0072] In some embodiments of the present application, the plurality of first heat exchange tubes 21 are arranged in two layers, the two layers of first heat exchange tubes 21 are arranged in the direction from the smoke inlet 11 to the smoke outlet 12, a part of the plurality of first heat exchange tubes 21 in the first layer of heat exchange tubes are set to be elliptical in cross section, another part of the plurality of first heat exchange tubes 21 in the first layer of heat exchange tubes are set to be circular in cross section, the second layer of heat exchange tubes is arranged below the first layer of heat exchange tubes, and each of the first heat exchange tubes 21 in the second layer of heat exchange tubes is set to be elliptical in cross section. When the water flows in the plurality of first heat exchange tubes 21, the water flow resistance in the first heat exchange tubes 21 can be further reduced, the insoluble substances can be further prevented from depositing in the first heat exchange tubes 21, thereby further preventing the water from vaporizing in the first heat exchange tubes 21, further slowing down the formation of scale in the first heat exchange tubes 21, and further prolonging the service performance and service life of the heating device 200.

[0073] In some embodiments of the present application, a disturbing member can be arranged on the heat exchange fin assembly 40, and the disturbing member is used to change the flow direction of the flue gas in the box body 10. After the high-temperature flue gas combusted by the burner flows into the box body 10 from the smoke inlet 11, the disturbing member can change the movement direction of the flue gas in the box body 10, thereby prolonging the movement time of the flue gas in the box body 10, so that the flue gas can be fully exchanged with the heat exchange fin assembly 40, the first heat exchange tubes 21, and the second heat exchange tubes 31, thereby improving the heating efficiency of the heating device 200 and improving the working performance of the heating device 200.

[0074] In some embodiments of the present invention, the disturbance element may include a flange disposed on the heat exchange fin assembly 40. This configuration simplifies the structure of the disturbance element, facilitates its manufacturing, and thus improves its production efficiency. Furthermore, the disturbance element and the heat exchange fin assembly 40 may be integrally formed, i.e., the disturbance element and the heat exchange fin assembly 40 are configured as a single integral part. This configuration reduces the number of components constituting the water tank assembly 100, improves the assembly efficiency of the water tank assembly 100, and thus improves its production efficiency.

[0075] like Figures 1-7 As shown, the heating device 200 according to an embodiment of the present invention can be a water heater or a wall-mounted boiler. The heating device 200 includes the water tank assembly 100 of the above embodiment. The water tank assembly 100 is disposed on the heating device 200. Each set of reciprocating heat exchange groups is connected to one of the first water boxes 131 and to two second water boxes 141 to form a series water circuit. The cross-section of each first heat exchange tube 21 is formed as an elongated strip and no baffles are provided in each first heat exchange tube 21. Compared with the prior art, it can make the water flow rate or water velocity in the main heat exchange tube assembly 20 and the condenser tube assembly 30 uniform, which can reduce water vaporization and scaling in the main heat exchange tube assembly 20 and the condenser tube assembly 30, and can also reduce the water flow resistance in the first heat exchange tube 21, avoiding blockage in the first heat exchange tube 21 and the second heat exchange tube 31. This can prevent the heating device 200 from dry burning and cracking, and thus extend the service life of the water tank assembly 100 and the heating device 200.
