Description

TECHNICAL FIELD

[0001] The utility model relates to gas transmission equipment technical field, specifically points to a kind of gas transmission pipe of stable connection fin, gas guide structure and gas cooling equipment. BACKGROUND

[0002] In modern industry and many equipment systems, as the key component of gas conveying and exchange, gas guide pipe is widely used in many fields such as automobile, aerospace, refrigeration, ventilation and so on. Its performance directly relates to the running efficiency, stability and energy consumption of the whole system. In order to improve the performance indicators such as heat exchange efficiency and gas conveying uniformity of the gas guide pipe, setting fins inside the gas guide pipe is a common and effective technical means. The setting of fins can significantly increase the contact area of gas in the gas guide pipe and the pipe wall, thereby strengthening the heat transfer process, so that heat can be more efficiently transferred from gas to pipe wall or from pipe wall to gas, thereby improving the heat exchange efficiency of the whole system.

[0003] At present, the combination of gas guide pipe and fin is increasingly common in some complex gas conveying and heat exchange systems. The gas guide pipe has a large flat cross section, which can provide a larger gas flow area and facilitate connection and integration with other components. The combination of the gas guide pipe and the fin can fully utilize the advantages of both and further optimize the performance of the system.

[0004] However, the existing combination technology of internal fin and gas guide pipe has obvious deficiencies. At present, the key problem to be solved is the low stability of the combination of fin and gas guide pipe. On the one hand, under the long-term impact of gas flow, due to the non-uniformity of gas flow and the change of pressure, the fin is prone to loosen or even separate from the gas guide pipe. This looseness can cause the position of the fin to shift, disrupting the originally designed gas flow channel and heat exchange path, thereby reducing the heat exchange efficiency and the stability of gas conveying. On the other hand, in some working environments with large vibrations or temperature changes, the combination part between the fin and the gas guide pipe will be subjected to additional stress. Due to the insufficient combination stability, these stresses can cause cracks or damage to the combination part, not only affecting the normal use of the gas guide pipe and the fin, but also possibly causing safety hazards such as gas leakage. In addition, the existing combination process such as welding often requires high processing precision and professional equipment, which also increases energy consumption and material consumption in the production process.

[0024] The utility model will be further described in the following in conjunction with the drawings and specific embodiments, so that the person skilled in the art can better understand the utility model and can be implemented, but the embodiment is not as the limitation of the utility model. Embodiment one

[0025] The embodiment provides a gas transmission pipe capable of stably connecting fins, which comprises a pipe body 100, a plurality of extrusion blocks 110 provided on the pipe body 100, the plurality of extrusion blocks 110 are respectively provided by protruding inward from the surface of the pipe body 100, and the two ends of the pipe body 100 in the length direction are in communication with the external environment; and corrugated fins 200 provided inside the pipe body 100, in the thickness direction of the corrugated fins 200, the opposite sides of the corrugated fins 200 are respectively in abutment with the plurality of extrusion blocks 110, and the gas to be transmitted moves along the length direction of the pipe body 100 inside the pipe body 100 through the corrugated fins 200.

[0026] The gas transmission pipe provided with the plurality of extrusion blocks 110 realizes the abutment of the pipe body 100 and the corrugated fins 200, so that the extrusion force of the corrugated fins 200 is generated, the friction between the pipe body 100 and the corrugated fins 200 is effectively increased, the stable connection of the corrugated fins 200 with the pipe body 100 is ensured in the long-term use process, and the problems such as loosening and displacement are avoided. Based on the above structure, the application ensures that the flow path of the gas in the pipe is more stable, reduces the gas flow turbulence caused by the shaking or displacement of the fins, thereby reducing the resistance of the gas transmission, improving the efficiency of the gas transmission, making the heat transfer more efficient and uniform, and significantly improving the cooling effect of the whole gas cooling equipment, and providing a reliable guarantee for the efficient and stable operation of the gas transmission and cooling equipment.

[0027] It should be noted that, for the convenience of description, the length direction of the pipe body 100 is defined as the first direction X, the width direction of the pipe body 100 is defined as the second direction Y, and the thickness direction of the pipe body 100 is defined as the third direction Z, wherein the first direction X, the second direction Y and the third direction Z are perpendicular to each other, and the first direction X and the second direction Y are located in the same plane.

[0028] Referring to Figure 1 and Figure 2 , the pipe body 100 in the embodiment is preferably a flat pipe, and the two sides in the thickness direction are connection surfaces 120 arranged in a plane structure, and the plurality of extrusion blocks 110 are symmetrically arranged on the connection surfaces 120, which are used for butt joint gas guiding on one hand, and also provide installation and connection space for the corrugated fins 200 on the other hand, and the pipe body 100 is preferably a flat pipe to maximize the contact area between the pipe body 100 and the corrugated fins 200 without affecting the gas transmission flow.

[0029] In this embodiment, the plurality of extrusion blocks 110 are arranged in a "comb-tooth" manner. Specifically, the plurality of extrusion blocks 110 are arranged in the center of the width direction of the pipe body 100 along the first direction X, and the remaining plurality of extrusion blocks 110 are symmetrically arranged on the pipe body 100 along the width direction of the pipe body 100. In the width direction of the pipe body 100, the plurality of extrusion blocks 110 on any side are uniformly spaced. This arrangement can lay a solid core support for the entire structure, so that when the pipe body 100 is connected with the corrugated fin 200, a stable force point can be formed in the central area, ensuring the balance and stability of the connection. The remaining extrusion blocks 110 are symmetrically distributed on the pipe body 100 along the width direction of the pipe body 100. This symmetric arrangement not only conforms to the principle of mechanics and can uniformly disperse stress, but also avoids loose or damaged connection caused by excessive local stress, and at the same time gives the entire structure a neat and beautiful visual effect.

[0030] Further, in the width direction of the pipe body 100, the plurality of extrusion blocks 110 on any side are uniformly spaced. The uniform spacing arrangement allows each extrusion block 110 to independently and effectively perform its function, avoiding the problem of poor connection caused by excessive concentration or dispersion of extrusion blocks 110. This uniformity ensures that the extrusion force received by each part is uniform during the connection of the pipe body 100 and the corrugated fin 200, thereby achieving a more stable and reliable connection.

[0031] In addition, in the actual production process, the "comb-tooth" arrangement has high regularity and symmetry, which makes the processing process more simple and efficient. Production personnel can use standardized processing procedures and equipment to reduce errors and uncertainties in the processing process, thereby reducing production costs, improving production efficiency, and achieving the optimal connection stability structure under the premise of ensuring connection stability.

[0032] In the embodiment, the protruding height of the plurality of extrusion blocks is set to 0.5 mm in combination with the size design of the actual corrugated fin 200 and the pipe body 100, so as to avoid extrusion damage to the corrugated fin 200 or the pipe body 100 due to excessive extrusion on the premise of being able to improve the friction stability of the corrugated fin 200 and the pipe body 100. Specifically, when the corrugated fin 200 and the pipe body 100 cooperate with each other, the protruding height of 0.5 mm enables the extrusion block 110 to form effective contact and extrusion with the corrugated fin 200, thereby increasing the friction between the two. In the gas transmission process, the gas flow inside the pipe body 100 will generate a certain impact force and vibration, and sufficient friction can ensure that the corrugated fin 200 can still be firmly attached to the pipe body 100 under such complex working conditions without problems such as loosening and displacement, thereby ensuring the stable operation of the entire gas transmission system. Therefore, if the protruding height is too low, it is difficult to realize the connection stability between the pipe body 100 and the corrugated fin 200. Correspondingly, if the protruding height of the extrusion block 110 is too large, excessive pressure will be applied to the corrugated fin 200 or the pipe body 100 during extrusion, which may cause damage such as deformation and rupture of the material. Once the corrugated fin 200 or the pipe body 100 is damaged, not only the connection stability between them will be affected, but also the performance and service life of the entire gas transmission system may be reduced. In different embodiments, the protruding height of the plurality of extrusion blocks 110 can be configured to 0.1-1.0 mm according to actual use requirements, and the utility model does not make specific limitations thereto.

In the embodiment, only the arrangement mode of the plurality of extrusion blocks 110 is different from that of embodiment one, specifically: in the embodiment, a long strip-shaped extrusion block 110 extending along the first direction X is arranged at the center of the pipe body 100, and the remaining extrusion blocks 110 are also arranged in a comb shape, thereby providing another pipe body 100 structure. Embodiment three

[0034] Referring to Figure 4 As shown in the figure, in the embodiment, in order to further simplify the preparation process of the extrusion block 110 and at the same time increase the range of use of the corrugated fin 200, the plurality of extrusion blocks 110 are configured in a point array structure.

Specifically, two ends of the plurality of the above-mentioned gas transmission pipes with stably-connectable fins in a first direction X are respectively arranged to penetrate to the outside of the assembling box, one end is connected with a high-temperature gas production device, and the other end is connected with a gas collecting device.

[0037] In summary, the gas transmission pipe with stably-connectable fins, the gas guide structure and the gas cooling device have the advantages of innovation in optimizing the gas transmission and heat exchange performance. Specifically, the gas transmission pipe is provided with a plurality of extrusion blocks 110, the extrusion blocks 110 realize the mutual abutment of the pipe body 100 and the corrugated fin 200, and then the extrusion blocks 110 can generate appropriate extrusion force on the corrugated fin 200, effectively increase the friction between the pipe body 100 and the corrugated fin 200, and ensure that the corrugated fin 200 always maintains stable connection with the pipe body 100 in the long-term use process, avoiding problems such as loosening and displacement. Based on the above structure, the application ensures that the flow path of the gas in the pipe is more stable, reduces the airflow turbulence caused by the fin shaking or displacement, thereby reducing the resistance of the gas transmission, improving the efficiency of the gas transmission, making the heat transfer more efficient and uniform, and significantly improving the cooling effect of the entire gas cooling device, providing reliable protection for the efficient and stable operation of the gas transmission and cooling device.
