DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] Please refer to Figures 1 to 4 The heat exchanger pipe assembly structure in the embodiment comprises a heat exchanger body 1, a heat exchange pipe 2 and a connecting pipe 3, and the heat exchanger body 1 is externally provided with a protective assembly;

[0023] The protective assembly comprises a sleeve 6 arranged outside the heat exchange pipe 2, a strip-shaped groove 7 is formed in the outer surface of the heat exchange pipe 2, a movable rod 8 is fixedly connected to the inner side of the strip-shaped groove 7, a sliding block 9 is slidingly connected to the outer surface of the movable rod 8, a threaded hole 10 is formed in the outer side of the sleeve 6, a positioning bolt 11 is threadedly connected to the inside of the threaded hole 10, and a sealing washer 12 is fixedly connected to the inside of the sleeve 6. After the heat exchange pipe 2 is connected to the connecting pipe 3, the worker only needs to pull the sleeve 6 to the left, so that the sliding block 9 slides on the outer surface of the movable rod 8, and the sleeve 6 is driven by the sliding block 9 to move close to the position of the connecting pipe 3, so that the sleeve 6 covers the position of the weld to shield and protect.

[0024] When the sleeve 6 is moved, the four positioning bolts 11 are tightened in sequence clockwise, so that the bottom end of the positioning bolt 11 continuously abuts against the outer side of the connecting pipe 3, thereby limiting the position of the sleeve 6 and ensuring the stability of the sleeve 6 to avoid the influence of external factors.

[0025] In addition, when the sleeve 6 is limited, at this time, the sealing washer 12 can fill the gap between the sleeve 6 and the connecting pipe 3, thereby enhancing the sealing performance and avoiding the water flow from penetrating to the position of the weld.

[0026] Compared with the existing pipe assembly structure, the present application achieves good protection effect, can protect the connection position of the heat exchange pipe 2 and the connecting pipe 3 to avoid the influence of external factors on the position of the weld, thereby reducing the probability of corrosion of the position of the weld by the water flow and fracture by external force, and improving the service life of the connecting pipe 3, which has good safety.

[0027] It should be noted that the number of positioning bolts 11 and the slider 9 is four, and the top of the slider 9 is fixedly connected with the inner wall of the sleeve 6.

[0028] The front end of the connecting pipe 3 is fixedly connected with a positioning ring 4, and the front end of the heat exchange pipe 2 is provided with an annular positioning groove 5, the outer diameter of the positioning ring 4 is smaller than the inner diameter of the annular positioning groove 5, and the outer diameters of the heat exchange pipe 2 and the connecting pipe 3 are the same. By setting the positioning ring 4 and the annular positioning groove 5, the auxiliary positioning effect can be achieved, so that the staff can butt the heat exchange pipe 2 and the connecting pipe 3 for welding.

[0029] Meanwhile, the outer side of the heat exchange pipe 2 is provided with a protective sleeve 13, the protective sleeve 13 is fixedly connected with the heat exchanger body 1, and the inner side of the protective sleeve 13 is bonded with a water-absorbing sponge 14. By setting the protective sleeve 13 and the water-absorbing sponge 14, the joint between the heat exchange pipe 2 and the heat exchanger body 1 can be protected. When water seeps into the joint, the water-absorbing sponge 14 will change color due to excessive water absorption, thereby prompting the staff to handle it in time.

[0030] In addition, the heat exchanger body 1 is fixedly connected with a protective plate 15 at the four corners, and the outer side of the protective plate 15 is bonded with a rubber pad 16. By setting the protective plate 15 and the rubber pad 16, the effect of protecting the four corners of the heat exchanger body 1 is achieved, thereby reducing the impact of bumps.

[0031] It should be understood that the heat exchange pipe 2 is fixedly installed on the left side of the heat exchanger body 1, and the front end and the rear end of the heat exchanger body 1 are fixedly connected with a dust screen.

[0032] The working principle of the above embodiment is as follows:

[0033] In use, the staff first needs to butt the connecting pipe 3 and the heat exchange pipe 2, so that the positioning ring 4 is inserted into the inner side of the annular positioning groove 5, so as to be simply inserted and fixed by the two, and the auxiliary positioning for welding is carried out, thereby facilitating the welding work. During the connection of the heat exchange pipe 2 and the connecting pipe 3, the staff only needs to pull the sleeve 6 to the left, so that the slider 9 slides on the outer surface of the movable rod 8, thereby driving the sleeve 6 to move close to the position of the connecting pipe 3, so that the sleeve 6 covers the welding position to shield and protect. When the sleeve 6 moves to the left, the four positioning bolts 11 are tightened in sequence, so that the bottom end of the positioning bolt 11 continuously abuts against the outer side of the connecting pipe 3, thereby limiting the position of the sleeve 6 and ensuring its stability, avoiding the influence of external factors. In addition, when the sleeve 6 is limited, the sealing gasket 12 can fill the gap between the sleeve 6 and the connecting pipe 3 at this time, thereby enhancing the sealing performance, and avoiding the water flow from penetrating into the welding position.
