Description

Technical Field

[0001] The present invention relates to the technical field of water heaters, and in particular to a heat exchange structure and a water heater. Background Art

[0002] The main heat exchange process of the gas water heater's heat exchanger is: the high-temperature flue gas generated by the combustion of gas in the burner transfers heat to the heat exchange plate, and then the heat exchange plate transfers the heat to the heat exchange tube welded to it. The heat exchange tube passes through the fins many times, and finally the inner wall of the heat exchange tube transfers the heat to the water, thereby heating the water.

[0003] However, the heat exchanger of the traditional gas water heater has low heat exchange efficiency and requires more gas to generate the same amount of heat, resulting in a higher cost for the gas water heater. Summary of the invention

[0004] Based on this, in order to solve the problem that the heat exchanger of traditional gas water heaters has low heat exchange efficiency and requires more gas to generate the same amount of heat, resulting in higher operating costs of gas water heaters, a heat exchange structure and water heater are proposed. When in use, the heat exchange structure and water heater have high heat exchange efficiency and can save operating costs.

[0005] The specific technical solutions are as follows:

[0006] On the one hand, the present application relates to a heat exchange element, which is provided with a heat exchange portion, the heat exchange portion is in a bent shape, the heat exchange portion is provided with a channel, and the channel is provided with a first water inlet for communicating with a water inlet pipe and a first water outlet for communicating with a water outlet pipe.

[0007] When the heat exchanger is in use, water enters the channel through the water inlet pipe, and the high-temperature flue gas generated by the heating element exchanges heat with the heat exchanger. Since the heat exchanger has a larger contact area with the flue gas than the straight plate at the same height and length, the heat exchange efficiency between water and flue gas can be indirectly improved. Moreover, the heat exchanger hinders the flow of flue gas to a certain extent, which can further improve the heat exchange efficiency between water and flue gas.

[0008] The technical solution is further described below:

[0009] In one embodiment, the channel is bent, and the bending trend of the channel is consistent with the bending trend of the heat exchange part. Thus, on the one hand, setting the channel in a bent shape and keeping the bending trend consistent with the bending trend of the heat exchange part can reduce the wall thickness of the channel, thereby improving the heat exchange efficiency between the water in the channel and the high-temperature flue gas; on the other hand, making the bending trend of the channel consistent with the bending trend of the heat exchange part facilitates the processing and forming of the channel.

[0010] In one embodiment, the cross section of the heat exchange portion is " 〉 "shape.

[0011] On the other hand, the present application also relates to a heat exchange structure, comprising the heat exchange element in any of the above embodiments.

[0012] When the heat exchange structure is in use, water enters the channel through the water inlet pipe, and the high-temperature flue gas generated by the heating element exchanges heat with the heat exchange element. Since the contact area between the heat exchange part and the flue gas is larger than that of the straight plate under the same height and length, the heat exchange efficiency between water and flue gas can be indirectly improved. Moreover, the heat exchange part hinders the flow of flue gas to a certain extent, which can further improve the heat exchange efficiency between water and flue gas.

[0013] The technical solution is further described below:

[0014] In one embodiment, it further comprises a water inlet pipe and a water outlet pipe, wherein the water inlet pipe is connected to the first water inlet, and the water outlet pipe is connected to the first water outlet. Thus, water is supplied to the channel through the water inlet pipe, and the water is discharged through the outlet pipe after heat exchange with the flue gas.

[0015] In one embodiment, the number of the heat exchange elements is at least two, the heat exchange elements are arranged at intervals, the first water inlet corresponding to each heat exchange element is connected to the water inlet pipe, and the first water outlet corresponding to each heat exchange element is connected to the water outlet pipe.

[0016] In one embodiment, the number of the heat exchange elements is multiple, at least two heat exchange elements are arranged at intervals along the first direction to form a heat exchange element layer, and the number of the heat exchange element layers is at least two layers and is arranged at intervals along the second direction. In this way, on the one hand, the more the number of heat exchange elements, the more sufficient the heat exchange between the heat exchange structure and the high-temperature flue gas, and the higher the utilization rate of the high-temperature flue gas; on the other hand, the arrangement of at least two layers of heat exchange element layers can increase the heat exchange area and more fully perform contact heat exchange with the high-temperature flue gas.

[0017] In one embodiment, it further includes a first diverter, the first diverter is provided with a first water storage chamber, and a second water inlet and a second water outlet both connected to the first water storage chamber, the number of the second water outlets is at least two, the water inlet pipe is connected to the first water inlet through the first diverter, one second water outlet corresponds to one first water inlet, and the second water inlet is connected to the water inlet pipe. Thus, when in use, the water inlet pipe transports water to the first water storage chamber, and the water is diverted to each second water outlet through the first water storage chamber, thereby diverting the water to each heat exchange element, so that each heat exchange element has water to exchange heat with the high-temperature flue gas, and the water is discharged from the water outlet pipe after the heat exchange is completed.

[0018] In one embodiment, the number of the second water outlets is multiple, at least two of the second water outlets are spaced apart along the third direction to form a water outlet layer, and the number of the water outlet layers is at least two layers and spaced apart along the fourth direction. In this way, the arrangement of the second water outlets is consistent with the arrangement of the heat exchange element, which facilitates the installation of the first diverter and the heat exchange element.

[0019] In one embodiment, it further includes a second diverter, the second diverter is provided with a second water storage chamber, and a third water inlet and a third water outlet both connected to the second water storage chamber, the number of the third water inlets is at least two, the water outlet pipe is connected to the first water outlet through the second diverter, one third water inlet corresponds to one first water outlet, and the third water outlet is connected to the water outlet pipe. In this way, when in use, after the water in each heat exchange element has completed heat exchange, it enters the second water storage chamber through the corresponding first water outlet and third water inlet, and then is discharged to the water outlet pipe through the second water storage chamber.

[0020] In one embodiment, there are multiple third water inlets, at least two of which are spaced apart along the fifth direction to form a water inlet layer, and there are at least two water inlet layers which are spaced apart along the sixth direction.

[0021] On the other hand, the present application also relates to a water heater, comprising the heat exchange structure in any one of the above embodiments; or the heat exchange element in any one of the above embodiments.

[0022] When the water heater is in use, water enters the channel through the water inlet pipe, and the high-temperature flue gas generated by the heating element exchanges heat with the heat exchange element. Since the contact area between the heat exchange part and the flue gas is larger than that of the straight plate under the same height and length, the heat exchange efficiency between water and flue gas can be indirectly improved. Moreover, the heat exchange part hinders the flow of flue gas to a certain extent, which can further improve the heat exchange efficiency between water and flue gas.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0038] The heat exchanger of a traditional gas water heater has low heat exchange efficiency and requires more gas to generate the same amount of heat, resulting in a higher cost for the gas water heater. Based on this, the present application proposes a heat exchange element 100, a heat exchange structure and a water heater 10. When the heat exchange element 100, the heat exchange structure and the water heater 10 are in use, they have high heat exchange efficiency and can save usage costs.

[0039] For details, please refer to Figure 1 The water heater 10 in one embodiment includes a heat exchange structure, a fin 200, a heating element and a fan. The fin 200 is provided with a mounting hole, and the heating element is passed through the mounting hole. The heat exchange structure and the fin 200 are both arranged between the fan and the heating element. The heating element heats the gas to generate high-temperature flue gas. The high-temperature flue gas passes through the heat exchange structure under the action of the fan and exchanges heat with the water in the heat exchange structure.

[0040] For further information, please refer to Figure 2 In one embodiment, the heat exchange structure includes a heat exchange element 100, the heat exchange element 100 is provided with a heat exchange portion 120, the heat exchange portion 120 is bent, the heat exchange portion 120 is provided with a channel 122, the channel 122 is provided with a first water inlet 1222 for communicating with the water inlet pipe 300 and a first water outlet for communicating with the water outlet pipe 400.

[0041] When the water heater 10 is in use, water enters the channel 122 through the water inlet pipe 300. When the high-temperature flue gas generated by the heating element exchanges heat with the heat exchange element 100, the heat exchange part 120 has a larger contact area with the flue gas than the straight plate under the same height and length, which can indirectly improve the heat exchange efficiency between water and flue gas. Moreover, the heat exchange part 120 hinders the flow of flue gas to a certain extent, which can further improve the heat exchange efficiency between water and flue gas.

[0042] Optionally, the water heater 10 may be a gas water heater.

[0043] It is necessary to point out that the heat exchange portion 120 in the heat exchange element 100 refers to the portion that directly contacts and exchanges heat with the flue gas generated by the heating element or the fins 200 .

[0044] Optionally, the heating element may be a component such as a heater that can heat the fuel gas; the fan may be a suction fan, through which the flue gas passes through the heat exchange structure for heat exchange.

[0045] Specifically, in one of the embodiments, the shape of the mounting hole matches the shape of the heat exchange portion 120 , so that the installation of the heat exchange element 100 can be facilitated.

[0046] For further information, please refer to Figure 2 , the channel 122 is in a bent shape, and the bending trend of the channel 122 is consistent with the bending trend of the heat exchange part 120. In this way, on the one hand, setting the channel 122 in a bent shape and keeping the bending trend consistent with the bending trend of the heat exchange part 120 can reduce the wall thickness of the channel 122, thereby improving the heat exchange efficiency between the water in the channel 122 and the high-temperature flue gas; on the other hand, making the bending trend of the channel 122 consistent with the bending trend of the heat exchange part 120 facilitates the processing and forming of the channel 122. Specifically, the heat exchanger 100 can be formed by bending a profile, or by welding a plurality of profiles separately, and the material used to make the heat exchanger 100 should be heat conductive.

[0047] Optionally, the heat exchanger 100 may be in the shape of an "H" shape, an "S" shape, or a "〉" shape, or other profiles with a bending structure. In order to improve the heat exchange effect of the heat exchanger 100, the channel 122 formed in the heat exchanger 100 may be configured to be similar to the structure of the heat exchanger 100 itself. For example, when the heat exchanger 100 is in the shape of an "H", the channel 122 may also be in the shape of an "H"; when the heat exchanger 100 is in the shape of an "S", the channel 122 may also be in the shape of an "S". Figure 2 As shown, the heat exchange portion 120 is in a “〉” shape, and the channel has a similar structure to the heat exchange portion 120 and is also in a “〉” shape. In this way, the wall thickness of the channel 122 can be reduced, thereby improving the heat exchange efficiency between the water and the high-temperature flue gas in the channel 122.

[0048] For further information, please refer to Figure 1 The heat exchange structure further includes a water inlet pipe 300 and a water outlet pipe 400. The water inlet pipe 300 is connected to the first water inlet 1222, and the water outlet pipe 400 is connected to the first water outlet. In this way, water is supplied to the channel 122 through the water inlet pipe 300, and the water is discharged through the water outlet pipe 400 after heat exchange with the flue gas.

[0049] For further information, please refer to Figure 3 The number of heat exchange elements 100 is at least two, and the heat exchange elements 100 are arranged at intervals. The first water inlet 1222 corresponding to each heat exchange element 100 is connected to the water inlet pipe 300, and the first water outlet corresponding to each heat exchange element 100 is connected to the water outlet pipe 400. In this way, when the heat exchange elements 100 are arranged at intervals, a gap is formed, and the high-temperature flue gas can flow along the gap, so that the flue gas can fully exchange heat with water.

[0050] For details, please refer to Figure 3 In one embodiment, there are multiple heat exchange elements 100, at least two heat exchange elements 100 are arranged at intervals along the first direction to form a heat exchange element layer, and the number of heat exchange element layers is at least two layers, and the heat exchange element layers are arranged at intervals along the second direction. In this way, on the one hand, the more the number of heat exchange elements 100 is, the more sufficient the heat exchange between the heat exchange structure and the high-temperature flue gas is, and the higher the utilization rate of the high-temperature flue gas is; on the other hand, setting at least two layers of heat exchange element layers can increase the heat exchange area and more sufficient contact and heat exchange with the high-temperature flue gas.

[0051] Optionally, the number of heat exchange elements 100 in a heat exchange element layer can be set according to heat exchange requirements and the size of the installation space, and it is only necessary to meet the interval arrangement of the heat exchange elements 100 in each heat exchange element layer.

[0052] Specifically, Figure 3 As shown, the first direction may be horizontal, and the second direction may be vertical; depending on the different assemblies, in other embodiments, the first direction may also be vertical, and the second direction may also be horizontal.

[0053] For further information, please refer to Figure 3 There are two layers of heat exchange elements, which are arranged at intervals in the longitudinal direction. At the same time, the heat exchange elements 100 in each layer of heat exchange elements are arranged at intervals in the transverse direction. Such an arrangement can hinder the flow of high-temperature flue gas, so that the high-temperature flue gas is in full contact with the heat exchange element 100, thereby improving the heat exchange effect between the high-temperature flue gas and the water in the heat exchange element 100.

[0054] Please refer to Figure 1 In this embodiment, the number of fins 200 is also multiple, and the fins 200 are arranged at intervals. The arrangement of the fins 200 is adapted to the arrangement of the heat exchange element 100. During installation, a single heat exchange element 100 is inserted with multiple fins 200 simultaneously in the horizontal direction.

[0055] Please refer to Figure 4 and Figure 5 On the basis of the above-mentioned embodiment, the heat exchange structure further includes a first diverter 500, the first diverter 500 is provided with a first water storage chamber, and a second water inlet 510 and a second water outlet 520 both connected to the first water storage chamber, the number of the second water outlets 520 is at least two, the water inlet pipe 300 is connected to the first water inlet 1222 through the first diverter 500, one second water outlet 520 corresponds to one first water inlet 1222, and the second water inlet 510 is connected to the water inlet pipe 300. In this way, when in use, the water inlet pipe 300 transports water to the first water storage chamber, and the water is diverted to each second water outlet 520 through the first water storage chamber, and then the water is diverted to each heat exchange element 100, so that the water distribution is realized, so that each heat exchange element 100 has water to exchange heat with the high-temperature flue gas, and the water is discharged from the water outlet pipe 400 after the heat exchange is completed.

[0056] Please refer to Figure 5 Specifically, the second water outlet 520 is bent, and its shape matches the shape of the first water inlet 1222 , so that it is easy to install between the first water inlet 1222 and the second water outlet 520 .

[0057] Please refer to Figure 5 Furthermore, in this embodiment, the number of the second water outlets 520 is multiple, at least two second water outlets 520 are spaced apart along the third direction to form a water outlet layer 530, the number of the water outlet layers 530 is at least two layers, and the water outlet layers 530 are spaced apart along the fourth direction; in this way, the arrangement of the second water outlets 520 is consistent with the arrangement of the heat exchange element 100, which facilitates the installation of the first diverter element 500 and the heat exchange element 100.

[0058] Specifically, Figure 5 As shown, the third direction may be horizontal, and the fourth direction may be vertical; depending on the different assemblies, in other embodiments, the third direction may also be vertical, and the fourth direction may also be horizontal.

[0059] Optionally, the number of the second water outlets 520 in the water outlet layer 530 can be set according to the number of heat exchange components, and the second water outlets 520 in each water outlet layer 530 can be arranged at intervals.

[0060] Specifically, in this embodiment, the first flow divider 500 is connected and fixed to the water inlet pipe 300 and the heat exchange element 100 by welding.

In this way, when in use, after the water in each heat exchange element 100 is heat exchanged, it enters the second water storage chamber through the corresponding first water outlet and the third water inlet 610, and then is discharged to the water outlet pipe 400 through the second water storage chamber.

[0062] Furthermore, when the above-mentioned heat exchange structure is in use, the water inlet pipe 300 transports water to the first water storage chamber, and the water is diverted to each second water outlet 520 through the first water storage chamber, and then the water is diverted to each heat exchange element 100. In this way, water distribution is achieved so that each heat exchange element 100 has water to exchange heat with the high-temperature flue gas. After the heat exchange is completed, the water is discharged from the water outlet pipe 400. When the heat exchange of the water in each heat exchange element 100 is completed, it enters the second water storage chamber through the corresponding first water outlet and the third water inlet 610, and then is discharged to the water outlet pipe 400 through the second water storage chamber.

In this way, the arrangement of the third water inlets 610 is consistent with the arrangement of the heat exchange element 100, which facilitates the installation of the second diverter 600 and the heat exchange element 100.

[0064] Specifically, Figure 7 As shown, the fifth direction may be horizontal, and the sixth direction may be vertical; depending on the different assemblies, in other embodiments, the fifth direction may also be vertical, and the sixth direction may also be horizontal.
