Description

Technical Field

[0001] This utility model relates to the field of heat exchange tube technology, and in particular to a condenser heat exchange tube. Background Technology

[0002] Heat exchange tubes are components of a heat exchanger installed in a condenser. They are placed inside the shell and used for the exchange of heat between two media. They have high thermal conductivity and good isothermal properties.

[0003] In the prior art, such as Chinese Patent Publication No. CN217877281U, a condenser heat exchange tube is disclosed, including a condenser box, support legs, an inlet pipe, an outlet pipe, slide rails, and heat exchange tube bodies. Support legs are installed at the four corners of the lower end of the condenser box. The inlet pipe vertically penetrates the upper left side of the condenser box, and the outlet pipe vertically penetrates the lower right side of the condenser box. Multiple slide rails are installed at the front and rear ends of the condenser box, and multiple slide rails are installed at the rear front end of the condenser box. Multiple heat exchange tube bodies are slidably installed inside the condenser box. This utility model has a simple structure. Multiple heat exchange tube bodies are installed by sliding installation. When cleaning or replacing the heat exchange tube bodies, it is only necessary to open the sealing cover and pull out the heat exchange tube body. Compared with the traditional cleaning method, it is not necessary to pull out the heat exchange tubes one by one, which is not only more labor-saving but also improves the efficiency of heat exchange tube installation and replacement.

[0004] In the aforementioned patent, it is only necessary to open the sealing cover and pull out the heat exchange tube body. Compared with the traditional cleaning method, it is not necessary to pull out the heat exchange tubes one by one. However, when the heat exchange tubes are connected to the external pipes using flanges, the bolt holes on the flanges need to be aligned and kept stable before the bolts are inserted into the bolt holes and tightened. If the two flanges are misaligned when tightening the bolts, it will be difficult to screw the bolts into the bolt holes, and realignment will be required, which reduces the connection efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the above-mentioned patent, where it is only necessary to open the sealing cover and pull out the heat exchange tube body. Compared with the traditional cleaning method, it is not necessary to pull out the heat exchange tubes one by one. However, when the heat exchange tube is connected to the external pipeline by flange, the bolt holes on the flange need to be aligned and kept stable before the bolts are inserted into the bolt holes and tightened. If the two flanges are misaligned when tightening the bolts, it will be difficult to screw the bolts into the bolt holes, and realignment is required, which reduces the connection efficiency. Therefore, this utility model proposes a condenser heat exchange tube.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a condenser heat exchange tube, comprising: a shell and a plurality of bolts, wherein a heat exchange tube body is provided on the inner surface of the shell, and both ends of the heat exchange tube body are fixedly connected to an inner flange, and slots are symmetrically opened on the left end face of the inner flange, inserts are inserted into the inner surfaces of the two slots, an outer flange is fixedly connected between the left surfaces of the two inserts, telescopic rods are fixedly connected to the inner surfaces of the two inserts, a locking block is fixedly connected to one end of the two telescopic rods, a spring is sleeved on the outer surface of the two telescopic rods, and locking grooves are symmetrically opened on the outer surface of the inner flange.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4As shown, this utility model provides a condenser heat exchange tube, including: a shell 1 and multiple bolts 6. A heat exchange tube body 2 is disposed on the inner surface of the shell 1. Inner flanges 3 are fixedly connected to both ends of the heat exchange tube body 2. Slots 7 are symmetrically opened on the left end face of the inner flanges 3. Insert blocks 15 are inserted into the inner surfaces of both slots 7. An outer flange 4 is fixedly connected between the left surfaces of the two insert blocks 15. Telescopic rods 13 are fixedly connected to the inner surfaces of both insert blocks 15. A locking block 14 is fixedly connected to one end of each of the two telescopic rods 13. Springs 12 are fitted on the outer surface of the telescopic rod 13. The outer surface of the inner flange 3 is symmetrically provided with slots 8. The inner surfaces of the two slots 8 are respectively connected to the inner surfaces of the two slots 7. The inner surfaces of the two slots 8 are respectively engaged with the outer surfaces of the two blocks 14. The cross sections of the two blocks 14 are inclined. The outer flange 4 and the inner flange 3 are fixedly connected by bolts 6. A connecting pipe 5 is fixedly connected to the left end face of the outer flange 4. The outer surfaces of the two blocks 14 are respectively matched with the inner surfaces of the two inserts 15.

[0024] The overall effect of Embodiment 1 is as follows: when installing the heat exchanger tube body 2 and the connecting pipe 5, after aligning the insert 15 on the outer flange 4 with the slot 7 on the inner flange 3, pressing is performed. During the pressing process, the inner wall of the slot 8 applies a certain squeezing force to the cross-section of the insert 14, causing the spring 12 and the telescopic rod 13 to compress, so that the insert 14 moves into the insert 15. When the insert 15 is fully inserted into the slot 8, the slot 8 no longer applies pressure to the insert 14, and thus, under the action of the spring 12 and the telescopic rod 13, the insert 14 is removed from the insert 15. The insert block 15 is pushed out and engaged in the slot 8, thus fixing the insert block 15 in the slot 7, completing the initial installation of the inner flange 3 and the outer flange 4. The through holes of the inner flange 3 and the outer flange 4 are quickly and stably aligned accurately. Then, the bolts 6 are inserted into multiple through holes in sequence and tightened with nuts to ensure the stability of the inner flange 3 and the outer flange 4 after connection. Then, the other end of the heat exchange tube body 2 is installed by repeating the above operation. By double-tightening the inner flange 3 and the outer flange 4, the convenience and stability of the installation are improved, and the practicality is high.

[0025] Example 2: As Figures 1-4 As shown, an annular block 10 is fixed on the left end face of the inner flange 3. An annular groove 11 is provided on the outer surface of the annular block 10. A rubber ring 9 is provided on the inner surface of the annular groove 11. A placement groove 16 is provided on the right end face of the outer flange 4. A rubber pad 17 is provided on the inner surface of the placement groove 16. The outer surface of the annular block 10 and the inner surface of the annular groove 11 are matched.

[0026] The effect achieved by the entire embodiment 2 is that after the outer flange 4 and the inner flange 3 are installed, the ring block 10 will be inserted into the placement groove 16, which will squeeze the rubber gasket 17 and cause the rubber gasket 17 to deform to fill the gap at the connection between the ring block 10 and the placement groove 16. At the same time, with the cooperation of the annular groove 11 and the rubber ring 9, the sealing of the connection is further guaranteed. Through double sealing, the sealing effect is good and the leakage of internal medium is prevented.

[0027] Working principle: When installing the heat exchanger tube body 2 and the connecting pipe 5, align the insert 15 on the outer flange 4 with the slot 7 on the inner flange 3 and press it down. During the pressing process, the inner wall of the slot 8 applies a certain squeezing force to the cross-section of the insert 14, causing the spring 12 and the telescopic rod 13 to compress, so that the insert 14 moves into the insert 15. When the insert 15 is fully inserted into the slot 8, the slot 8 no longer applies pressure to the insert 14. Thus, under the action of the spring 12 and the telescopic rod 13, the insert 14 is pushed out from the inside of the insert 15 and engaged in the slot 8, so that the insert 15 is limited and fixed in the slot 7, completing the initial installation of the inner flange 3 and the outer flange 4, quickly and stably installing the insert 15. The through holes of the inner flange 3 and the outer flange 4 are accurately aligned. Then, the bolts 6 are inserted into the multiple through holes in sequence and tightened with nuts to ensure the stability of the connection between the inner flange 3 and the outer flange 4. After the outer flange 4 and the inner flange 3 are installed, the ring block 10 will be inserted into the placement groove 16 to compress the rubber gasket 17, causing the rubber gasket 17 to deform and fill the gap at the connection between the ring block 10 and the placement groove 16. At the same time, with the cooperation of the annular groove 11 and the rubber ring 9, the sealing of the connection is further guaranteed. Then, the other end of the heat exchange tube body 2 is installed by repeating the above operation. By double-tightening the inner flange 3 and the outer flange 4, the convenience and stability of the installation are improved, and the practicality is high.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
