DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

The plate 7 is fixed, the first fixing plate 6 and the second fixing plate 7 are both provided with a first slot for the first bolt 8 to pass through, the number of a group of carrier plates 9 is two, and a plurality of fins 10 are fixed between a group of carrier plates 9, and the plurality of fins 10 are arranged linearly, and a plurality of connecting plates 11 are fixed on one side of the fin 10, and the cross section of the connecting plate 11 is an arc-shaped structure, and the connecting plate 11 is tightly fitted with the heat exchange tube 5. The use of the arc-shaped connecting plate 11 can help the fin 10 to be better connected with the heat exchange tube 5, so that the heat transfer effect between the heat exchange tube 5 and the fin 10 is better, and the connecting plate 11 increases the contact surface between the two, which can prevent the thinner fin 10 from scratching the heat exchange tube 5, and a plurality of second bolts 12 are arranged on the two carrier plates 9 on the same side of the fin 10, and the plurality of second bolts 12 are used to fix the two carrier plates 9;

[0024] The first fixing plate 6 on the fixing tube 4 is fixed to the second fixing plate 7 on the heat exchange tube 5 by using the first bolt 8, so that the fixing tube 4 is connected to the heat exchange tube 5, and the heat exchange medium can be transmitted. When a heat exchange tube 5 is damaged, it can be disassembled and replaced separately, and the connecting plate 11 on the fin 10 is fitted with the heat exchange tube 5. The fins 10 arranged on both sides of the heat exchange tube 5 can be fixed to the heat exchange tube 5 by using the second bolt 12, so that the heat exchange tube 5 and the fin 10 are designed to be detachable. In this way, the heat exchange tube 5 is more convenient to repair or replace, and the repair cost is effectively reduced.

[0025] Among them, a rubber pad 13 is arranged between the two carrier plates 9 located on the same side of the fin 10, and a second slot for the second bolt 12 to pass through is opened on the carrier plate 9 and the rubber pad 13. The rubber pad 13 provides support for the two carrier plates 9 when they are fixed by the second bolt 12 to prevent the two carrier plates 9 from being deformed due to excessive clamping.

[0026] The carrier plate 9 is provided with a plurality of through holes 14 which are arranged linearly. The plurality of through holes 14 on the carrier plate 9 can reduce the obstruction of the carrier plate 9 to the plurality of fins 10 during gas flow.

[0027] Among them, a plurality of reinforcing ribs 15 are fixed on the fin 10 , and the plurality of reinforcing ribs 15 are arranged linearly. The reinforcing ribs 15 arranged on the fin 10 can help the fin 10 to conduct heat better and enhance the stability of the structural form of the fin 10 .

[0028] The rotary connector includes an infusion tube 16, a rotary joint 17 and a first ring plate 18. The rotary joint 17 is arranged between the catheter tube 3 and the infusion tube 16, and the rotary joint 17 is used for the communication between the catheter tube 3 and the infusion tube 16. The first ring plate 18 is fixedly sleeved on the outside of the catheter tube 3. The outside of the infusion tube 16 is fixedly sleeved with a second ring plate 19, and the second ring plate 19 is threadedly connected with a third bolt 20. The first ring plate 18 is provided with a plurality of slots 21 distributed in a circular array. The third bolt 20 is clearance-matched with the inner wall of the slot 21, and the outside of the third bolt 20 is fixedly sleeved with a limit block 22.

[0029] The rotary joint 17 is used to connect the catheter 3 and the infusion tube 16, so that the interface angle of the infusion tube 16 can be adjusted as needed, and the third bolt 20 is tightened with a wrench so that the third bolt 20 is inserted into the corresponding slot 21. In this way, the third bolt 20 can lock the position of the first ring plate 18 and the second ring plate 19, thereby locking the position of the catheter 3 and the infusion tube 16, so that the position of the interface of the infusion tube 16 is locked, thereby ensuring the stability of the heat exchanger when connected. The design of the limit block 22 can prevent the third bolt 20 from completely detaching from the second ring plate 19.

[0030] Working principle of this utility model:

[0031] When performing heat exchange between gas and liquid, the two infusion tubes 16 can be rotated first, and the angles of the interfaces of the two infusion tubes 16 can be adjusted so that the two infusion tubes 16 can be better connected to the liquid supply pipeline. After the infusion tube 16 is connected to the liquid supply pipeline, the third bolt 20 is screwed with a wrench so that the third bolt 20 is inserted into the corresponding slot 21, and the position of the infusion tube 16 and the liquid guide tube 3 is locked, so that the infusion tube 16 cannot continue to rotate compared to the liquid guide tube 3. When the liquid flows through the heat exchange tube 5 in sequence, the multiple fins 10 arranged on the outside of the heat exchange tube 5 can help the gas and liquid complete the heat exchange;

[0032] Each pipe in the finned heat exchanger may develop cracks due to corrosion after long-term use. The remaining pipes not wrapped by the fins 10 have a larger operating space when repaired, and the repair is relatively convenient. The heat exchange tube 5 wrapped by the fins 10 is difficult to operate because the multiple fins 10 are arranged too closely. At this time, it is necessary to remove the second bolt 12 to separate the two groups of carrier plates 9. In this way, the fins 10 are peeled off from the outside of the heat exchange tube 5, so that the heat exchange tube 5 is exposed, and the first bolts 8 at the upper and lower ends of the damaged heat exchange tube 5 are removed, so that the damaged heat exchange tube 5 can be replaced separately. Afterwards, the two groups of carrier plates 9 are locked again with the second bolt 12, so that the fins 10 are wrapped around the outside of the heat exchange tube 5 again, and the heat exchange tube 5 is cooperated to perform heat exchange work.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
