Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application.

[0035] Please refer to Figures 1 to 10 The present application provides a technical solution: a fin heat exchanger convenient to install and replace, comprising a conveying pipe 1 conveying heat transfer medium, the conveying pipe 1 is composed of two straight pipes and a bent pipe, the diameter of the bent pipe is the same as that of the two straight pipes, and the two ends of the two straight pipes and the bent pipe are all welded and installed with a circular ring, a plurality of threaded holes for butt joint are arranged on the circular ring, after the two straight pipes are assembled together through the bent pipe, the adjacent circular rings are screwed together through a screw rod, so that the two straight pipes and the bent pipe are assembled into the conveying pipe 1 for conveying heat transfer medium.

[0036] A heat exchange pipe 2 for heat exchange is installed in the conveying pipe 1, the heat exchange pipe 2 is also composed of two straight pipes with a smaller diameter than the conveying pipe 1 and a bent pipe, which facilitates the local extension of the heat exchange pipe 2 into the conveying pipe 1 for heat exchange, and the heat exchange pipe 2 is installed and fixed with existing lifting rings and other structural members through the part exposed outside the conveying pipe 1, and a plurality of circular rings are welded on the outer wall of one of the straight pipes, and a plurality of fins are formed on the circular rings, the one end of the two straight pipes is welded and installed with a head to realize opening closure, and the other end is welded and installed with a circular ring, the outer wall of the circular ring is provided with external threads, the two ends of the bent pipe are provided with threaded grooves matched with the external threads, the circular ring with external threads on the straight pipe is screwed into the threaded groove on the bent pipe, that is, the complete heat exchange pipe 2 is assembled, and according to the use requirement, holes are formed on the heat exchange pipe 2 and the conveying pipe 1 for connecting the remaining pipes, which needs to be referred to the actual use requirement, and will not be described in detail here, when the heat exchange pipe 2 needs to be disassembled in the later stage, the straight pipe is rotated until the circular ring is screwed out of the threaded groove, so that the heat exchange pipe 2 can be conveniently disassembled for cleaning.

[0037] The bottom end of the conveying pipe 1 is provided with a support assembly for fixing the position of the conveying pipe 1 and the heat exchange pipe 2. The support assembly comprises a bottom plate 3 abutting the ground. The bottom plate 3 is welded with an extended protruding pattern on the surface according to the weight of the actually installed conveying pipe 1, so as to increase the contact area between the bottom plate 3 and the ground, avoid the shaking or even overturning of the bottom plate 3 due to the off-center of gravity and the too small contact area between the bottom plate 3 and the ground during the later disassembly process of the conveying pipe 1. A plurality of threaded holes are formed in the bottom plate 3. By penetrating the anchor rod through the threaded holes in the bottom plate 3 and extending into the ground, the stability of the bottom plate 3 can be improved. A first support vertical plate 4 is welded and installed on the top left side of the bottom plate 3. A recess is arranged at the top end of the first support vertical plate 4. Threaded holes are arranged on the inner walls of the front and rear sides of the recess. A rotating shaft with the same diameter as the threaded holes is penetrated through the two threaded holes in the first support vertical plate 4. A bracket is welded and installed on the top end outer wall of the rotating shaft. The width of the bracket is the same as the width of the recess in the first support vertical plate 4, so that the rotating shaft cannot be pulled out of the threaded holes in the first support vertical plate 4. A horizontal plate 5 for supporting the conveying pipe 1 is welded and installed on the top end of the bracket. A T-shaped sliding groove is arranged at the top end of the horizontal plate 5. The left side of the T-shaped sliding groove is in an open state. A T-shaped plate 6 with the same shape as the T-shaped sliding groove is slidably installed in the T-shaped sliding groove. A plurality of protrusions are welded and installed on the top end of the T-shaped plate 6. The plurality of protrusions are equally distributed on the same central axis. A plurality of first clamps 8 are sleeved on the outer wall of the conveying pipe 1. Each first clamp 8 comprises two arc-shaped plates with the same curvature as the straight pipe of the conveying pipe 1 and a screw rod. The two arc-shaped plates are hingedly connected. The bottom ends of the two arc-shaped plates are provided with extended protruding structures (with the same width and height as the protrusions on the T-shaped plate 6). Threaded holes are arranged in the protrusions on the T-shaped plate 6 and the extended protruding structures on the arc-shaped plates. The screw rod is penetrated through the protrusions and the extended protruding structures, so that the first clamps 8 sleeved on the outer wall of the conveying pipe 1 are fixed on the top end of the T-shaped plate 6. When the straight pipe of one of the conveying pipe 1 structures above the T-shaped plate 6 is disassembled, the T-shaped plate 6 is pulled out from the left side of the T-shaped sliding groove, so that a gap is formed between the straight pipe and the elbow pipe above the T-shaped plate 6, which facilitates the descaling of the inner walls of the elbow pipe and the straight pipe. After the descaling is completed, the T-shaped plate 6 is pushed back to its original position, so that the conveying pipe 1 can be disassembled without the help of lifting equipment. After the descaling and maintenance or replacement of parts are completed, the T-shaped plate 6 is controlled to slide into the T-shaped sliding groove again. At this time, the straight pipe of the conveying pipe 1 structure is abutted to the elbow pipe.
