AI Technical Summary
为了增强换热，现在一般是采用增加翅片的结构，由于热管换热器本身处于水和烟气的双重环境下，在烟气环境下，增加翅片本身又会造成积灰，反过来又降低了换热效率，在水环境下，增加翅片则会造成对水的扰流，增加水流的阻力，因此，有必要对于热管换热器的使用环境，设计一种是既适用于烟气，又适用于水的换热器结构
1.本申请采用斜向设置的翅片子板，对于烟气以及水流都能起到导向作用，尽可能的减少阻力，通过设置流通通道，增加局部扰动的同时，还能提高水流或者烟气流的流通性，降低阻力。

Description
Technical Field
[0001] This application relates to a heat exchange tube body for a heat pipe heat exchanger. Background Technology
[0002] A heat pipe heat exchanger is a heat exchanger device that uses a heat exchange medium to recover heat from flue gas. Its core component is the heat exchange tube structure. To enhance heat exchange, a structure with added fins is generally used. However, since heat pipe heat exchangers operate in both water and flue gas environments, adding fins in the flue gas environment can lead to ash accumulation, which in turn reduces heat exchange efficiency. In the water environment, adding fins can cause turbulence and increase water flow resistance. Therefore, it is necessary to design a heat exchanger structure suitable for both flue gas and water environments. Utility Model Content
[0003] To address the aforementioned problems, this application proposes a heat exchanger tube body for a heat pipe heat exchanger, comprising a tube body with a plurality of finned units disposed on the outer side of the tube body. Each finned unit includes two finned sub-plates obliquely arranged relative to the outer surface of the tube body. The two finned sub-plates of the same finned unit are obliquely arranged in the same direction, and a flow gap is provided between the finned sub-plates. The finned unit has a plurality of through holes. This application uses obliquely arranged finned sub-plates, which can guide both flue gas and water flow, minimizing resistance. By setting up flow channels, it increases local disturbance while also improving the flowability of water or flue gas, further reducing resistance.
[0004] Preferably, symmetrical flow gaps are formed on the upper and lower sides of the finned plate.
[0005] Preferably, the thickness of the finned plate gradually decreases along the direction away from the flow gap. This application employs a gradually thinning design, which reduces flow resistance and, combined with the oblique arrangement, provides the overall plate with a certain degree of flow guiding capability.
[0006] Preferably, the through hole is disposed on the finned plate.
[0007] Preferably, the finned plate includes an upper inner arc snap-fit plate disposed above the tube body and a lower inner arc snap-fit plate disposed below the tube body, and an outer side plate is disposed on the outer side of the upper inner arc snap-fit plate and the lower inner arc snap-fit plate.
[0008] Preferably, the through-hole includes an inner through-hole disposed on the upper inner arc retaining plate and the lower inner arc retaining plate, and an outer through-hole disposed on the outer side plate. This application provides inner through-holes not only on the outer side but also on the inner side, allowing internal airflow or water flow to exit through the inner and outer through-holes after being obstructed, thus maximizing heat exchange efficiency while minimizing obstruction to the flow direction of water or flue gas.
[0009] Preferably, the upper inner arc clamping plate and the lower inner arc clamping plate are symmetrically arranged relative to the pipe body.
[0010] Preferably, the finned plate is welded to the outer wall of the tube body.
[0011] Preferably, the through holes on the finned plate are arranged opposite to each other.
[0012] This application can bring the following beneficial effects: 1. This application uses obliquely arranged finned plates, which can guide both flue gas and water flow, minimize resistance, and increase local disturbance while improving the flow of water or flue gas and reducing resistance by setting up flow channels.
[0013] 2. This application adopts a gradually thinning design, which can reduce flow resistance and, together with the oblique setting, give the whole thing a certain flow guiding capacity.
[0014] 3. This application provides an internal through-hole not only on the outside but also on the inside, which allows the internal airflow or water flow to exit through the internal and external through-holes after being obstructed, thereby maximizing heat exchange efficiency while minimizing obstruction to the flow direction of water or flue gas.

[0019] To clearly illustrate the technical features of this solution, the following detailed description, in conjunction with the accompanying drawings, will be provided.
[0020] In the first embodiment, such as Figure 1-2 As shown, a heat exchange tube body for a heat pipe heat exchanger includes a tube body 1. Several finned units 2 are arranged on the outer side of the tube body 1. Each finned unit 2 includes two finned plates 3 that are obliquely arranged relative to the outer surface of the tube body 1. The two finned plates 3 of the same finned unit 2 are obliquely arranged in the same direction. A flow gap 4 is provided between the finned plates 3. Several through holes 5 are provided on the finned unit 2.
[0021] In use, this application serves as the tube body of a heat pipe heat exchanger. Both sides are equipped with the same structure with finned plates 3. On one side, flue gas heats the medium inside the tube body 1, while on the other side, the heated medium exchanges heat with water on the outside, absorbing the heat of the medium inside the tube body 1. The obliquely arranged finned plates 3 of this application can guide both flue gas and water flow, minimizing resistance. By setting up flow channels, it can increase local disturbance while improving the flowability of water or flue gas, thus reducing resistance.
[0022] In the second embodiment, as Figure 1-4 As shown, a heat exchange tube body for a heat pipe heat exchanger includes a tube body 1. Several finned units 2 are arranged on the outer side of the tube body 1. Each finned unit 2 includes two finned plates 3 that are obliquely arranged relative to the outer surface of the tube body 1. The two finned plates 3 of the same finned unit 2 are obliquely arranged in the same direction. A flow gap 4 is provided between the finned plates 3. Several through holes 5 are provided on the finned unit.
[0023] Flow gaps 4 are symmetrically arranged on the upper and lower sides of the finned plate 3. The thickness of the finned plate 3 gradually decreases in the direction away from the flow gaps 4.
[0024] The through hole 5 is disposed on the finned plate 3. The finned plate 3 includes an upper inner arc retaining plate 6 disposed above the tube body 1 and a lower inner arc retaining plate 7 disposed below the tube body 1, and an outer plate 8 is disposed on the outer side of the upper inner arc retaining plate 6 and the lower inner arc retaining plate 7. The through hole 5 includes an inner through hole 9 disposed on the upper inner arc retaining plate 6 and the lower inner arc retaining plate 7 and an outer through hole 10 disposed on the outer plate 8. The upper inner arc retaining plate 6 and the lower inner arc retaining plate 7 are symmetrically disposed relative to the tube body 1.
[0025] The finned plate 3 is welded to the outer wall of the tube body 1. The through holes 5 on the finned plate 3 are arranged opposite each other, i.e., correspondingly arranged. The opposite through holes 5 can form a line parallel to the tube body 1.
[0026] In use, this application serves as the tube body of a heat pipe heat exchanger. Both sides are equipped with the same structure of finned plates 3. The finned plates 3 are welded to the outer wall of the tube body 1. On one side, flue gas heats the medium inside the tube body 1, while on the other side, the heated medium exchanges heat with water on the outside, absorbing the heat of the medium inside the tube body 1. The obliquely arranged finned plates 3 of this application have flow gaps 4 between them, which guide the flow of flue gas and water, minimizing resistance. By setting flow channels, the local disturbance is increased, while the flow of water or flue gas is improved, and the resistance is reduced.
[0027] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
