Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a heat exchanger that is easy to maintain. Background Technology

[0002] A heat exchanger is a device that enables heat transfer between two or more fluids. It is widely used in chemical, petroleum, energy, and refrigeration industries. Common types include shell-and-tube, plate, and finned heat exchangers. Due to prolonged use, heat exchangers often require disassembly. Shell-and-tube heat exchangers typically use multiple bolts to connect the shell side to the cover plate, requiring the removal of these bolts for disassembly. This makes maintenance cumbersome and inconvenient. Utility Model Content

[0003] The purpose of this invention is to solve the problem that the existing technology requires the removal of multiple bolts during disassembly, which leads to the disadvantage of heat exchanger maintenance, and to propose a heat exchanger that is easy to maintain.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A heat exchanger designed for easy maintenance includes a heat exchanger body. Multiple through holes are equally spaced at both ends of the heat exchanger body. A connecting post is installed within each of the multiple through holes. The multiple connecting posts are fixedly connected to a cover plate. A connecting groove is provided on each of the multiple connecting posts. An abutment block is installed within each of the multiple connecting grooves. An inclined surface is provided on each of the multiple abutment blocks, and the inclined surface abuts against the connecting groove. The multiple abutment blocks are connected by a connecting mechanism.

[0005] Preferably, the connecting mechanism includes a rotating ring, which is rotatably connected to the heat exchanger body via a bearing, and the outer wall of the rotating ring is fixedly connected to a plurality of abutment blocks.

[0006] Preferably, the bearing is a thrust ball bearing.

[0007] Preferably, each of the abutment blocks has an insertion hole.

[0008] Preferably, a connecting lug is fixedly connected to the rotating ring, a fixing lug is fixedly connected to the heat exchanger body, a positioning post is provided through the fixing lug, the positioning post passes through the connecting lug, and a connecting part is fixedly connected to the end of the positioning post.

[0009] Preferably, the connecting part is a magnet, and the fixing ear is made of iron.

[0010] The present invention provides a heat exchanger that is easy to maintain. The advantages are as follows: multiple abutment blocks are connected by a connecting mechanism so that multiple abutment blocks can be moved out of the connecting groove together, releasing the limiting position on the connecting column, thereby facilitating the removal of the cover plate and allowing the cover plate to be removed for heat exchanger maintenance.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example 1: Refer to Figure 1-4 A heat exchanger designed for easy maintenance includes a heat exchanger body 2. Multiple through holes 13 are equally spaced at both ends of the heat exchanger body 2. Each through hole 13 contains a connecting post 4, which is fixedly connected to a cover plate 1. Each connecting post 4 has a connecting groove 8, and each connecting groove 8 contains an abutment block 5. Each abutment block 5 has an inclined surface 7 that abuts against the connecting groove 8. The abutment blocks 5 are connected by a connecting mechanism. Inserting the connecting post 4 into the through hole 13 initially limits the position of the cover plate 1. Rotating the abutment block 5 into the connecting groove 8 fixes the connecting post 4 with the inclined surface 7, preventing axial movement. When disassembly is required, the connecting mechanism connects the abutment blocks 5, allowing them to be moved out of the connecting groove 8 together, releasing the limiting effect on the connecting post 4 and facilitating the removal of the cover plate 1 for maintenance.

[0015] The connecting mechanism includes a rotating ring 3, which is rotatably connected to the heat exchanger body 2 via a bearing. The outer wall of the rotating ring 3 is fixedly connected to multiple abutment blocks 5. By using multiple rotating rings 3, multiple abutment blocks 5 can be rotated simultaneously, so that multiple abutment blocks 5 can disengage at the same time.

[0016] The bearing is a thrust ball bearing. Since the bearing is subjected to axial force, a thrust ball bearing capable of handling axial force loads is used.

[0017] Example 2: Refer to Figure 3-4 As another preferred embodiment of this utility model, based on embodiment 1, multiple abutment blocks 5 are provided with insertion holes 6. Since it is relatively difficult to rotate the rotating ring 3, by inserting a rod into one of the insertion holes 6, the torque during rotation is increased, so that the rod rotates around the heat exchanger, thereby driving multiple abutment blocks 5 to move simultaneously, and firmly abutting the inclined surface 7 with the connecting groove 8.

[0018] Example 3: Reference Figure 3-4 As another preferred embodiment of this utility model, based on embodiment 2, a connecting ear 10 is fixedly connected to the rotating ring 3, and a fixing ear 9 is fixedly connected to the heat exchanger body 2. A positioning post 11 is provided through the fixing ear 9 and passes through the connecting ear 10. A connecting part 12 is fixedly connected to the end of the positioning post 11. By inserting the positioning post 11 into the fixing ear 9 and the connecting ear 10, the rotating ring 3 is limited, preventing the inclined surface 7 from disengaging from the connecting groove 8 and ensuring the fixing effect of the connecting post 4.

[0019] The connecting part 12 is a magnet, and the fixing ear 9 is made of iron. The fixing ear 9 is coated with anti-rust paint to prevent corrosion. The fixing ear 9 is attracted by the magnet to prevent the connecting post 4 from detaching.

[0020] During disassembly and maintenance, the positioning of the rotating ring 3 is released by pulling out the connecting part 12. The rod is inserted into the insertion hole 6, causing the rod to rotate around the heat exchanger, which will drive the rotating ring 3 to rotate. When the rotating ring 3 rotates, it will drive multiple abutment blocks 5 to move simultaneously, so as to disengage the inclined surface 7 from the connecting groove 8, release the fixing of the connecting column 4, and move the cover plate 1 to disengage the connecting column 4 from the through hole.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
