Abstract
Description
Technical Field
[0001] This utility model relates to the field of finned tube technology, and in particular to a finned tube device for a heat exchanger. Background Technology
[0002] Finned plate and tube heat exchangers are heat exchange devices suitable for high-temperature gas phases. Finned plates are stacked on heat exchange tubes to form an indirect heat exchanger. To further increase the heat exchange density, the finned plates are connected to multiple heat exchange tubes. However, in existing finned tubes, the fins are directly welded to the pipes and cannot be disassembled. This makes cleaning inconvenient for workers, and long-term use leads to the accumulation of dirt, affecting the heat conduction effect.
[0003] Therefore, it is necessary to invent a finned tube device for a heat exchanger to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a finned tube device for a heat exchanger to solve the problems mentioned in the background art.

[0008] The lower finned tube assembly includes a second arc-shaped plate, and the inner sidewall of the second arc-shaped plate is integrally formed with a second arc-shaped strip adapted to the arc-shaped groove. The second arc-shaped plate and the first arc-shaped plate form a circular tube.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This utility model provides, for example Figure 1-8 The finned tube assembly of a heat exchanger shown includes a delivery tube assembly 1, an upper finned tube assembly 2 installed on the top of the delivery tube assembly 1, and a lower finned tube assembly 3 installed on the bottom of the delivery tube assembly 1. The delivery tube assembly 1 includes a tube body 101, and the outer wall of the tube body 101 is provided with a plurality of arc-shaped grooves 102 arranged in a ring array. By setting the plurality of arc-shaped grooves 102, the first arc-shaped strip 202 and the second arc-shaped strip 302, the contact area between the delivery tube assembly 1 and the upper finned tube assembly 2 and the delivery tube assembly 1 and the lower finned tube assembly 3 can be increased, thereby improving the heat exchange effect.
[0028] Furthermore, the upper finned tube assembly 2 includes a first arc-shaped plate 201. The inner sidewall of the first arc-shaped plate 201 is integrally formed with a first arc-shaped strip 202 that matches the arc-shaped groove 102. The outer sidewall of the first arc-shaped plate 201 is fixedly provided with a plurality of first fins 203, and the plurality of first fins 203 are distributed at equal intervals. The middle of both sides of the outer sidewall of the first arc-shaped plate 201 is integrally formed with a first extension plate 204. The bottom end of the first extension plate 204 is inlaid with a first magnet 205. The ends of both sides of the outer sidewall of the first arc-shaped plate 201 are symmetrically integrally formed with first protrusions 206. A retaining plate 207 is movably provided between two adjacent first protrusions 206 through a pin. The inner sidewall of the retaining plate 207 is provided with a retaining groove 208.
[0029] The lower finned tube assembly 3 includes a second arc-shaped plate 301, and the inner sidewall of the second arc-shaped plate 301 is integrally formed with a second arc-shaped strip 302 adapted to the arc-shaped groove 102. The second arc-shaped plate 301 and the first arc-shaped plate 201 form a circular tube. A plurality of second fins 303 are fixedly provided on the outer sidewall of the second arc-shaped plate 301. The adjacent ends of the first fins 203 and the second fins 303 have gaps to facilitate the movement of the latch plate 207. The plurality of second fins 303 are evenly distributed. The two ends of the outer sidewall of the second arc-shaped plate 301 are symmetrically and integrally formed with second extension plates 304 corresponding to the first extension plate 204. The top of the second extension plate 304 is inlaid with a second magnet 305 with the opposite magnetism to the first magnet 205. The two ends of the outer sidewall of the second arc-shaped plate 301 are symmetrically and integrally formed with a second extension plate 304 corresponding to the first extension plate 204. The top of the second extension plate 304 is inlaid with a second magnet 305 with the opposite magnetism to the first magnet 205. The assembly is integrally formed with a second protrusion 306 corresponding to the first protrusion 206. A locking rod 307 adapted to the locking groove 208 is fixedly arranged between two adjacent second protrusions 306. Through the arrangement of the conveying pipe assembly 1, the upper finned tube assembly 2, and the lower finned tube assembly 3, the finned tube is designed as a split design of the upper finned tube assembly 2 and the lower finned tube assembly 3. The upper finned tube assembly 2 and the lower finned tube assembly 3 are connected by the locking groove 208 on the locking plate 207 and the locking rod 307, so that the upper finned tube assembly 2 and the lower finned tube assembly 3 can be disassembled from the conveying pipe assembly 1. This facilitates the cleaning of the multiple first fins 203 and second fins 303 on the upper finned tube assembly 2 and the lower finned tube assembly 3, preventing the accumulation of dirt, which would cause a decrease in heat conduction and affect the heat exchanger's heat exchange effect.
[0030] Working principle of this utility model:
[0031] During disassembly, first pull the clamping plate 207 to rotate, causing the clamping rod 307 to disengage from the inside of the clamping slot 208, thus disengaging the upper finned tube assembly 2 and the lower finned tube assembly 3. Then, pull the upper finned tube assembly 2 and the lower finned tube assembly 3 in the opposite direction, causing the second magnet 305 and the first magnet 205 to no longer attract each other, thereby disassembling the upper finned tube assembly 2 and the lower finned tube assembly 3.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
