Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchange equipment technology, and in particular to a heat exchanger module that is easy to maintain. Background Technology
[0002] A heat exchanger is an energy-saving device that enables heat transfer between two or more fluids at different temperatures. It transfers heat from a higher-temperature fluid to a lower-temperature fluid, ensuring that the fluid temperature reaches the specified parameters of the process to meet the requirements of the process conditions. It is also one of the main pieces of equipment for improving energy efficiency.
[0003] After prolonged use, heat exchangers require maintenance. However, existing maintenance methods, such as the easily maintained floating coil heat exchanger disclosed in patent application CN 208653253U, involve multiple bolts connecting the first flange on the inlet pipe to the second flange on the outlet pipe, and the first flange on the outlet pipe to the second flange on the inlet pipe. Maintenance requires removing these bolts one by one, a time-consuming and labor-intensive process that significantly increases maintenance costs and time consumption. Furthermore, since the piping is integrally mounted on the heat exchanger, its integrated structure makes fault location and partial replacement difficult, limiting modular maintenance and leading to inefficiency and increased risk of component damage. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a heat exchanger module that is easy to maintain.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A heat exchanger module that is easy to maintain includes a heat exchanger shell. Rectangular slots are provided on both sides of the outer wall of the heat exchanger shell. Protective side plates are snapped into the rectangular slots. Five sets of fixing blocks are fixedly connected to the outer wall of the heat exchanger shell, and each set of fixing blocks has four blocks.
[0007] Each set of fixing blocks has a support rod fixedly connected to its outer wall. The end of the support rod is provided with a connecting rod. The end of the connecting rod is connected to an upper fastening bracket via a connecting shaft. Several positioning pins are fixedly connected to the bottom of the upper fastening bracket. A lower fastening bracket is provided on the outer wall of the heat exchanger shell below the upper fastening bracket. The outer wall of the lower fastening bracket has a positioning groove that mates with the positioning pins. A telescopic sleeve is engaged between the upper fastening bracket and the lower fastening bracket.
[0008] Preferably, the end of the outermost fixed block is connected to a drive rod via a support rod. The drive rod has a movable groove on the side away from the support rod, and a drive handle is provided in the movable groove. The drive handle is movably connected to the drive rod via a rotating shaft.
[0009] Preferably, the outer surface of the drive handle is fitted with a limiting arch-shaped component, and the bottom of the limiting arch-shaped component is connected to the outer wall of the heat exchanger shell by fasteners.
[0010] Preferably, the upper and lower fastening brackets are provided with arc-shaped slots on opposite sides, and the telescopic sleeve is connected to the upper and lower fastening brackets respectively through the arc-shaped slots.
[0011] Preferably, the outer wall of the heat exchanger shell has a plurality of mounting holes, and the end of the telescopic sleeve passes through the mounting holes and extends into the interior of the heat exchanger shell and is connected to a guide pipe.
[0012] Preferably, an upper port and a lower port are provided on one side of the outer wall of the heat exchanger shell, and both the upper port and the lower port are in communication with the interior of the heat exchanger shell.
[0013] Preferably, the outer surface of the drive handle is covered with an anti-slip protective cover.
[0014] The beneficial effects of this utility model are:
[0015] Using the drive handle, the drive rod rotates counterclockwise around the support rod. The drive rod causes the upper fastening bracket at the bottom of the connecting rod to deflect to one side and move upward. When the upper fastening bracket moves, it helps to disengage the positioning pin from the positioning groove and loosen the individual telescopic sleeve from the arc-shaped groove. Subsequently, the telescopic sleeve disengages from the end of the guide tube, achieving the effect of removing the individual guide tube from the heat exchanger without disassembling the entire guide tube. This enables independent modular maintenance of the guide tube, greatly improving the efficiency of maintenance work. Attached Figure Description

[0025] Example:
[0026] Reference Figure 1-4 A heat exchanger module that is easy to maintain includes a heat exchanger shell 1. Rectangular slots are provided on both sides of the outer wall of the heat exchanger shell 1. Protective side plates 2 are snapped into the rectangular slots. Five sets of fixing blocks 3 are fixedly connected to the outer wall of the heat exchanger shell 1, and each set of fixing blocks 3 has four blocks.
[0027] Each set of fixing blocks 3 has a support rod 4 fixedly connected to its outer wall. The end of the support rod 4 is provided with a connecting rod 5. The end of the connecting rod 5 is connected to an upper fastening seat 6 through a connecting shaft. Several positioning posts 7 are fixedly connected to the bottom of the upper fastening seat 6. A lower fastening seat 8 is provided on the outer wall of the heat exchanger shell 1 below the upper fastening seat 6. The outer wall of the lower fastening seat 8 is provided with a positioning groove 9 that cooperates with the positioning posts 7. A telescopic sleeve 10 is engaged between the upper fastening seat 6 and the lower fastening seat 8.
[0028] The end of the outermost fixed block 3 is connected to a drive rod 11 via a support rod 4. A movable groove is provided on the side of the drive rod 11 away from the support rod 4. A drive handle 12 is provided in the movable groove. The drive handle 12 is movably connected to the drive rod 11 via a rotating shaft.
[0029] The outer surface of the drive handle 12 is fitted with a limiting arch 13, and the bottom of the limiting arch 13 is connected to the outer wall of the heat exchanger housing 1 by fasteners 14.
[0030] Both the upper fastening bracket 6 and the lower fastening bracket 8 have arc-shaped slots on their opposite sides, and the telescopic sleeve 10 is connected to the upper fastening bracket 6 and the lower fastening bracket 8 respectively through the arc-shaped slots.
[0031] The outer wall of the heat exchanger shell 1 has several mounting holes. The end of the telescopic sleeve 10 passes through the mounting holes and extends into the interior of the heat exchanger shell 1 and is connected to the guide pipe 15.
[0032] An upper port 16 and a lower port 17 are provided on one side of the outer wall of the heat exchanger shell 1. Both the upper port 16 and the lower port 17 are connected to the interior of the heat exchanger shell 1.
[0033] The outer surface of the drive handle 12 is covered with an anti-slip protective cover.
[0034] In this embodiment, when maintenance of the heat exchanger shell 1 is required, the fastener 14 at the bottom of the limiting arch member 13 is first removed from the heat exchanger shell 1. Then, the drive handle 12 is rotated to an angle perpendicular to the drive rod 11, and the drive handle 12 is engaged in the movable groove. At this time, the drive handle 12 is held and rotated counterclockwise. When the drive handle 12 rotates counterclockwise, it drives the drive rod 11 to rotate around the support rod 4. When the drive rod 11 rotates, it drives the connecting rod 5 at one end to rotate counterclockwise. When the connecting rod 5 rotates, it drives the upper fastener at its bottom. The card holder 6 deflects to one side and moves upward. When the upper fastening card holder 6 moves upward, it causes the bottom positioning post 7 to disengage into the positioning groove 9 on the lower fastening card holder 8. This allows the single telescopic sleeve 10 to disengage from the arc-shaped slot and become loose. At the same time, the telescopic sleeve 10 is disengaged from the end of the guide tube 15 and removed. After the telescopic sleeve 10 is removed, the guide tube 15 becomes loose inside the heat exchanger shell 1. This allows the single guide tube 15 to be directly removed from inside the heat exchanger shell 1 for independent inspection and maintenance without disassembling the entire guide tube 15, thus improving the efficiency of the entire maintenance process.
