Gas heat exchanger and heat exchange components

Abstract

This invention relates to a gas heat exchanger and a heat exchange assembly. The gas heat exchanger includes a heat exchange channel and a heat exchange assembly, which includes multiple first heat exchange fins and multiple second heat exchange fins. The multiple first fins are stacked, and the multiple second fins are stacked. High-temperature flue gas can enter through the gap between two adjacent first fins, heating the first heat exchange tube. The flue gas can further flow between the second fins, heating the second heat exchange tube. Since one side of a single second fin is inserted between two adjacent first fins, and there is a gap between one side of the second fin and the first fin, the gap between adjacent first fins is separated by the second fins. Utilizing the viscosity of the flue gas, the velocity of the flue gas flowing from between the first fins to between the second fins is reduced, thereby extending the overall flow time of the flue gas within the heat exchange assembly, improving the heat exchange efficiency of the flue gas, and reducing the waste of gas resources.

Description

Technical Field

[0001] This invention relates to the field of heat exchange technology, and in particular to gas heat exchangers and heat exchange components. Background Technology

[0002] The traditional heat exchanger process involves the high-temperature flue gas produced by the combustion of gas transferring heat to the heat exchange fins, which then transfer the heat to the connected heat exchange tubes. Finally, the heat exchange tubes heat the water inside. However, traditional gas heat exchangers have low heat exchange efficiency, requiring more gas to generate the same amount of heat, thus increasing the cost of gas resources. Summary of the Invention

[0003] Therefore, it is necessary to provide a gas heat exchanger and heat exchange components that can effectively improve heat exchange efficiency, in order to address the problem of low heat exchange efficiency leading to increased gas costs.

[0004] A heat exchange assembly, the heat exchange assembly comprising:

[0005] Multiple first fins, stacked together, with a spacing between adjacent first fins; and

[0006] Multiple second fins are stacked together, with a gap between adjacent second fins. Multiple first fins and multiple second fins are arranged in two rows, one above the other. One side of a single second fin is inserted between two adjacent first fins, and there is a gap between one side of the second fin and the first fin.

[0007] In one embodiment, a second fin is inserted between each pair of adjacent first fins.

[0008] In one embodiment, a guide portion is provided on one side of the second fin facing the first fin, the guide portion being located between two adjacent first fins, and the guide portion being inclined toward one of the two adjacent first fins.

[0009] In one embodiment, the guide portion has a gap between its side away from the second fin and an adjacent first fin.

[0010] In one embodiment, the first fin is provided with a first blocking portion, which is disposed toward the adjacent guide portion.

[0011] In one embodiment, a drainage portion is provided on the side of the first fin away from the second fin, and the drainage portion is inclined toward the adjacent first fin.

[0012] In one embodiment, the first fin is disposed below the second fin.

[0013] In one embodiment, the first fin and the second fin have the same structure.

[0014] A gas heat exchanger, the gas heat exchanger comprising:

[0015] The heat exchange components as described above; and

[0016] The heat exchange channel includes a first heat exchange tube and a second heat exchange tube. One end of the first heat exchange tube passes through a plurality of stacked first fins and is connected to the second heat exchange tube. The end of the second heat exchange tube away from the first heat exchange tube passes through a plurality of stacked second fins.

[0017] In one embodiment, the gas heat exchanger further includes a heat exchange box, and the heat exchange components are disposed inside the heat exchange box.

[0018] In one embodiment, the gas heat exchanger further includes a water inlet pipe connected to the end of the first heat exchange tube away from the second heat exchange tube.

[0019] In use, the aforementioned gas heat exchanger and heat exchange components consist of multiple stacked first fins and multiple stacked second fins. There is a gap between adjacent first fins and between adjacent second fins, and the first and second fins are arranged in two rows. High-temperature flue gas can enter through the gap between adjacent first fins, heating the first heat exchange tube. Furthermore, the flue gas can flow between the second fins, heating the second heat exchange tube. Since one side of a single second fin is inserted between adjacent first fins, and there is a gap between one side of the second fin and the first fin, the second fins can separate the gaps between adjacent first fins. Utilizing the viscosity of the flue gas, the velocity of the flue gas flowing from between the first fins to between the second fins is reduced, thereby extending the overall flow time of the flue gas within the heat exchange components, improving the heat exchange efficiency, and reducing gas resource waste.

[0030] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] See Figure 1 and Figure 2The gas heat exchanger 10 in one embodiment of the present invention can at least improve heat exchange efficiency, thereby reducing the waste of gas resources. Specifically, the gas heat exchanger 10 includes a heat exchange component 100 and a heat exchange channel 200. The heat exchange channel 200 passes through the heat exchange component 100, and the heat exchange component 100 realizes heat exchange on the heat exchange channel 200, thereby heating the water or other fluids in the heat exchange channel 200.

[0032] Please see Figure 2 and Figure 3 In one embodiment, the heat exchange assembly 100 includes a plurality of first fins 110 and a plurality of second fins 120. The plurality of first fins 110 are stacked, with a gap between adjacent first fins 110. The plurality of second fins 120 are stacked, with a gap between adjacent second fins 120. The plurality of first fins 110 and the plurality of second fins 120 are arranged in two rows. One side of a single second fin 120 is inserted between two adjacent first fins 110, and there is a gap between one side of the second fin 120 and the first fin 110. The heat exchange channel 200 includes a first heat exchange tube 210 and a second heat exchange tube 220. One end of the first heat exchange tube 210 passes through the plurality of stacked first fins 110 and is connected to the second heat exchange tube 220. The end of the second heat exchange tube 220 away from the first heat exchange tube 210 passes through the plurality of stacked second fins 120.

[0033] In use, the aforementioned gas heat exchanger 10 and heat exchange assembly 100 consist of multiple stacked first fins 110 and multiple stacked second fins 120. Since there is a gap between adjacent first fins 110 and between adjacent second fins 120, the first fins 110 and second fins 120 are arranged in two rows. High-temperature flue gas can then enter through the gap between adjacent first fins 110, heating the first heat exchange tube 210. Furthermore, the flue gas can flow between the second fins 120, heating the second heat exchange tube 220. One side of a single second fin 120 is inserted between two adjacent first fins 110, and there is a gap between one side of the second fin 120 and the first fin 110. Furthermore, by separating the gap between two adjacent first fins 110 through the second fin 120, the viscosity of the flue gas is utilized to reduce the speed of the flue gas flowing from between the first fins 110 to between the second fins 120, thereby extending the overall flow time of the flue gas between the heat exchange components 100, improving the heat exchange efficiency of the flue gas, and reducing the waste of gas resources.

[0034] In this embodiment, a plurality of first fins 110 are stacked in a row, and a plurality of second fins 120 are stacked in a row, with the plurality of first fins 110 and the plurality of second fins 120 arranged in two rows, one above the other.

[0035] Please see Figure 3 and Figure 5 In one embodiment, a second fin 120 is inserted between each pair of adjacent first fins 110. By evenly inserting multiple second fins 120 between multiple first fins 110, the uniformity of high-temperature flue gas distribution can be improved, thereby improving the uniformity of heat exchange in the heat exchange channel 200 and increasing heat exchange efficiency. Of course, in other embodiments, two or more other numbers of second fins 120 can be inserted between two adjacent first fins 110, as long as the second fins 120 can be used to separate the spacing between the first fins 110 and reduce the time it takes for flue gas to flow from between the first fins 110 to between the second fins 120.

[0036] In one embodiment, the first fin 110 is disposed below the second fin 120. Since the high-temperature flue gas generated by the combustion gas flows upwards, it first flows between the first fins 110 and then from between the first fins 110 to the second fin 120. Because the flue gas remains between the first fins 110 for a longer period, the heat exchange efficiency between the first fins 110 and the first heat exchange tube 210 is improved. In other embodiments, the positions of the first fins 110 and the second fin 120 can also be set according to the flue gas flow direction, so that along the flue gas flow direction, the flue gas first passes through the first fin 110 and then through the second fin 120.

[0037] In one embodiment, the first fin 110 and the second fin 120 of the present invention have the same structure. Setting the structures of the first fin 110 and the second fin 120 to be the same can effectively improve processing efficiency and reduce processing costs. Of course, in other embodiments, the structures of the first fin 110 and / or the second fin 120 can be adjusted according to actual installation requirements so that the structures of the first fin 110 and the second fin 120 are not the same.

[0038] In this embodiment, the first fin 110 and the second fin 120 are copper sheets. Since copper has good thermal conductivity, the thermal conductivity of the heat exchange assembly 100 can be guaranteed.

[0039] In one embodiment, the number of first fins 110 is the same as the number of second fins 120. Specifically, there are 42 first fins 110 and 42 second fins 120. Alternatively, the number of first fins 110 and second fins 120 can be appropriately increased or decreased according to the size of the gas heat exchanger 10. In other embodiments, the number of first fins 110 may not be the same as the number of second fins 120.

[0040] Please see Figure 3 and Figure 5 In one embodiment, a guide portion 121 is provided on one side of the second fin 120 facing the first fin 110. The guide portion 121 is located between two adjacent first fins 110 and is inclined towards one of the adjacent first fins 110. By providing the guide portion 121, the flow of flue gas from between the first fins 110 to between the second fins 120 can be guided. Since the guide portion 121 is inclined between two adjacent first fins 110, the flue gas can fully contact the second fin 120 along the guide portion 121, thereby maximizing heat transfer and reducing heat loss.

[0041] Specifically, the guide portion 121 has a gap between it and an adjacent first fin 110. Because the guide portion 121 is inclined and has a gap with the first fin 110, a portion of the flue gas located between the first fins 110 can flow directly into one side of the second fin 120 along the gap between the guide portion 121 and the first fin 110, resulting in a fast flue gas flow rate. Another portion can flow along the other side of the guide portion 121 to the opposite side of the corresponding second fin 120. This extends the residence time of the flue gas between the first fins 110 while ensuring a certain heat exchange capacity of the second fin 120, thereby improving heat exchange efficiency and reducing the waste of fuel resources. In other embodiments, the side of the guide portion 121 away from the second fin 120 can also be attached to a first fin 110.

[0042] In this embodiment, the guide portion 121 is integrally formed on the second fin 120, thereby improving the stability of the guide portion 121 on the second fin 120 and improving the smoothness of the guide portion 121 in guiding flue gas. Specifically, the guide portion 121 is formed by extending from one side of the second fin 120 toward the first fin 110. By bending one side of the second fin 120 toward the first fin 110, the guide portion 121 is inclined relative to the first fin 110. In other embodiments, the guide portion 121 and the second fin 120 can also be separately provided, and the guide portion 121 can be fixed to the second fin 120 by welding, gluing, snap-fitting, or other methods.

[0043] Please see Figure 3 and Figure 4 In one embodiment, a first blocking portion 112 is provided on the first fin 110. By providing the first blocking portion 112, the residence time of flue gas between the first fins 110 can be further increased, the heat exchange efficiency of the flue gas can be improved, heat loss can be reduced, the waste of gas resources can be reduced, and the cost of using gas can be indirectly reduced.

[0044] Specifically, the first blocking portion 112 is disposed toward the adjacent guide portion 121. Since the guide portion 121 is inclined toward one of the two adjacent first fins 110, by disposing the first blocking portion 112 disposed on the other first fin 110 toward the guide portion 121, the flue gas flowing along the guide portion 121 to the second fin 120 can be blocked, further prolonging the time the flue gas remains between the first fins 110. In other embodiments, the first blocking portion 112 may be omitted.

[0045] In one embodiment, at least two first blocking portions 112 are disposed at intervals on a single first fin 110. By distributing the first blocking portions 112 at intervals, flow space can be provided for the flow of flue gas after heat exchange, preventing the flue gas from remaining stagnant between the first fins 110 and affecting the heat exchange efficiency. In other embodiments, there may be only one first blocking portion 112.

[0046] Specifically, different first blocking portions 112 are spaced apart on a single first fin 110, and the first heat exchange tube 210 is located between two adjacent first blocking portions 112. There are no first blocking portions 112 on the first fin 110 at the position of the first heat exchange tube 210, so the flue gas that has come into contact with the first heat exchange tube 210 and exchanged heat can flow into the second fin 120 through the space between two adjacent first blocking portions 112, while the flue gas that has not exchanged heat will be blocked between the first fins 110 by the first blocking portions 112, so as to improve the heat exchange efficiency and reduce heat loss.

[0047] In one embodiment, a flow guide 114 is provided on the side of the first fin 110 away from the second fin 120, and the flow guide 114 is inclined toward the adjacent first fin 110. Since the flue gas generated by combustion flows between two adjacent first fins 110, the flow guide 114 can achieve the effect of guiding the flue gas, so that the flue gas can fully contact the first fin 110, thereby fully transferring heat, reducing heat loss, and improving heat exchange efficiency.

[0048] In this embodiment, the flow guide 114 is integrally formed on the first fin 110, thereby improving the stability of the flow guide 114 on the first fin 110 and improving the smoothness of the flow guide 114 in guiding flue gas. Specifically, the flow guide 114 is formed by extending from one side of the first fin 110 away from the second fin 120. The flow guide 114 is inclined by bending one side of the first fin 110 toward the adjacent first fin 110. In other embodiments, the flow guide 114 and the first fin 110 can also be separately provided, and the flow guide 114 can be fixed to the first fin 110 by welding, gluing, snap-fitting, or other methods.

[0049] Please refer to it again. Figure 3 and Figure 5 In one embodiment, a second blocking portion 122 is further provided on the second fin 120, and the second blocking portion 122 is disposed on the side of the second fin 120 facing the adjacent second fin 120. By providing the second blocking portion 122, the residence time of flue gas between the second fins 120 can be further increased, the heat exchange efficiency of the flue gas can be improved, heat loss can be reduced, the waste of gas resources can be reduced, and the cost of gas usage can be indirectly reduced. In other embodiments, the second blocking portion 122 may be omitted.

[0050] In one embodiment, the second blocking portion 122 on a single second fin 120 can be one, two, or more, with different second blocking portions 122 spaced apart. By spaced-aparting the second blocking portions 122, flow space can be provided for the flow of flue gas after heat exchange, preventing the flue gas after heat exchange from continuing to stagnate between the second fins 120 and affecting the heat exchange efficiency.

[0051] Specifically, different second blocking portions 122 are spaced apart on a single second fin 120, and the second heat exchange tube 220 is located between two adjacent second blocking portions 122. The second fin 120 does not have a second blocking portion 122 at the position of the second heat exchange tube 220, so the flue gas that has come into contact with and exchanged heat with the second heat exchange tube 220 can flow out between two adjacent second blocking portions 122, while the flue gas that has not undergone heat exchange will be blocked between the second fins 120 by the second blocking portions 122, thereby improving heat exchange efficiency and reducing heat loss.

[0052] Please see Figure 2 and Figure 3 In one embodiment, a first through hole is formed on the first fin 110, and the first through holes on different first fins 110 are connected. A first heat exchange tube 210 passes through the first through hole. A second through hole is formed on the second fin 120, and the second through holes on different second fins 120 are connected. A second heat exchange tube 220 passes through the second through hole.

[0053] In one embodiment, the first blocking part 112 is located above the first through hole or above the axis of the first through hole, thereby facilitating the further heat exchange between the flue gas blocked by the first blocking part 112 and the first heat exchange tube 210 in the first through hole.

[0054] In one embodiment, the second blocking part 122 is located above the second through hole or above the axis of the second through hole, thereby facilitating the further heat exchange between the flue gas blocked by the second blocking part 122 and the second heat exchange tube 220 in the second through hole.

[0055] In this embodiment, a single first fin 110 has three spaced first through holes, each of which can be inserted into a first heat exchange tube 210, and the different first heat exchange tubes 210 are interconnected. Of course, in other embodiments, the first fin 110 may have other numbers of first through holes, as long as the first heat exchange tubes 210 can be effectively inserted.

[0056] In this embodiment, a single second fin 120 has two spaced second through holes, each of which can be inserted into a second heat exchange tube 220, and the different second heat exchange tubes 220 are interconnected. Of course, in other embodiments, the second fin 120 may have other numbers of second through holes, as long as the second heat exchange tubes 220 can be effectively inserted.

[0057] In this embodiment, there are three first heat exchange tubes 210 and two second heat exchange tubes 220. The first heat exchange tubes 210 and the second heat exchange tubes 220 are interconnected to facilitate water flow. Specifically, one end of each first heat exchange tube 210 is connected to one second heat exchange tube 220, and the two second heat exchange tubes 220 are interconnected. The other two of the three first heat exchange tubes 210 are interconnected and connected to the connected second heat exchange tubes 220, so that the three first heat exchange tubes 210 and the two second heat exchange tubes 220 form a water flow channel. Therefore, the direction of water flow can be from one first heat exchange tube 210 into the two interconnected second heat exchange tubes 220, and then from the second heat exchange tubes 220 into the other two interconnected first heat exchange tubes 210. Since water first enters the first heat exchange tube 210, and the first heat exchange tube 210 exchanges heat with the first fin 110 and the flue gas between the first fin 110, the temperature difference between the first heat exchange tube 210, the first fin 110 and the flue gas is large, which can improve the heat exchange efficiency.

[0058] In other embodiments, the number of the first heat exchange tube 210 and the second heat exchange tube 220 can be other numbers, and the connection method can be other methods, as long as water can flow and exchange heat between the first heat exchange tube 210 and the second heat exchange tube 220.

[0059] Optionally, a first support portion 116 is provided at the first through hole on the first fin 110, and the first support portion 116 abuts against the first heat exchange tube 210. By providing the first support portion 116, the stability of the first heat exchange tube 210 passing through the first through hole can be improved. At the same time, since the first support portion 116 abuts against the first fin 110, the heat conduction area of ​​the first fin 110 to the first heat exchange tube 210 can be increased, further improving the heat exchange efficiency.

[0060] Optionally, a second support portion 123 is provided at the second through hole on the second fin 120, and the second support portion abuts against the second heat exchange tube 220. By providing the second support portion 123, the stability of the second heat exchange tube 220 passing through the second through hole can be improved. At the same time, since the second support portion 123 is provided on the second fin 120, the heat conduction area of ​​the second fin 120 to the second heat exchange tube 220 can be increased, further improving the heat exchange efficiency.

[0061] Please refer to it again. Figure 1 and Figure 2 In one embodiment, the gas heat exchanger 10 further includes a water inlet pipe 300, which is connected to the end of the first heat exchange tube 210 away from the second heat exchange tube 220. By providing the water inlet pipe 300, water flow is facilitated into the first heat exchange tube 210, and the water entering the first heat exchange tube 210 first exchanges heat with the first fin 110 and the flue gas between the first fins 110, effectively improving the heat exchange efficiency of the water flow within the first heat exchange tube 210. In other embodiments, the water inlet pipe 300 may also be connected to the second heat exchange tube 220.

[0062] In one embodiment, the gas heat exchanger 10 further includes a water outlet pipe 400, which is connected to the end of another first heat exchange tube 210 away from the second heat exchange tube 220. The water inlet pipe 300, the first heat exchange tube 210, the second heat exchange tube 220, and the water outlet pipe 400 form a water flow channel. The water outlet pipe 400 facilitates the outlet of hot water. In other embodiments, the water outlet pipe 400 may also be connected to the end of the second heat exchange tube 220 away from the first heat exchange tube 210.

[0063] In one embodiment, the gas heat exchanger 10 further includes a heat exchange box 500, and the heat exchange component 100 is disposed within the heat exchange box 500. By providing the heat exchange box 500, a circulation space for the flue gas after combustion is easily formed. The flue gas can be effectively stored in the heat exchange box 500 and flow into the heat exchange component 100 within the heat exchange box 500, thereby achieving heat exchange with the heat exchange channel 200.

[0064] In one embodiment, the gas heat exchanger 10 further includes a coil 600, which is wound around the heat exchange box 500. The water inlet pipe 300 is connected to the first heat exchange tube 210 via the coil 600. By configuring the coil 600 to be wound around the heat exchange box 500, the heat in the heat exchange box 500 can be further utilized, thereby further improving heat exchange efficiency and avoiding heat waste.
