Description

Technical Field

[0001] This utility model relates to the energy field, and in particular to a heat pipe structure for a heat exchanger. Background Technology

[0002] A heat pipe structure for a heat exchanger is a device that utilizes the phase change of the working fluid, the absorption of heat during liquid vaporization, the release of heat during gaseous liquefaction, and capillary action to achieve efficient heat transfer. Its core consists of a tube shell, a capillary wick, and a working fluid. After the tube is evacuated, the working fluid is injected. It absorbs heat from the heat source in the evaporation section, causing the working fluid to vaporize. The vapor releases heat and liquefies in the condensation section. The liquid working fluid then flows back to the evaporation section through the capillary wick, thus completing the heat transfer cycle. Its function is to achieve industrial waste heat recovery and power generation in the energy field by virtue of its advantages such as high thermal conductivity, isothermal properties, and adjustable heat flux density.

[0003] A heat pipe structure for a heat exchanger mainly consists of a shell, a capillary wick, and a working fluid. The shell is mostly made of metal, forming a sealed cavity. The capillary wick is attached to the inner wall of the shell and is usually composed of metal mesh, sintered metal, or grooves. It drives the recirculation of the working fluid through capillary action. The working fluid is the heat transfer medium filled inside the pipe. In a vacuum environment, heat transfer is achieved through a phase change process of liquid vaporization absorbing heat and gas liquefaction releasing heat. The synergistic effect of the three components enables the heat pipe to efficiently transfer heat from the evaporation section to the condensation section.

[0004] In existing technologies, heat pipe failures inside heat exchangers are difficult to repair by partial disassembly, requiring the entire heat exchanger to be disassembled. This results in cumbersome and time-consuming maintenance procedures, directly impacting production line operations and increasing costs. Therefore, a heat pipe structure for heat exchangers is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a heat pipe structure for a heat exchanger, aiming to improve the problem of difficulty in replacing heat exchange tubes in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A heat pipe structure for a heat exchanger includes a shell, a tube bundle frame slidably connected inside the shell, a plurality of connecting rods rotatably connected inside the shell, a rotating plate fixedly connected to the outside of each of the connecting rods, two limiting grooves formed on the outside of each connecting rod, a plurality of sliders slidably connected inside the shell, a spring fixedly connected to the far side of two sliders, a connecting rod fixedly connected to the near side of two sliders, and a limiting block fixedly connected to the near side of two connecting rods.

[0008] As a further description of the above technical solution:

[0009] The outer side of the housing has two heat exchange heads that are detachably connected, and each heat exchange head is fixedly connected to the outer side of the housing by multiple fixing plates;

[0010] As a further description of the above technical solution:

[0011] The fixing plate is internally threaded with bolts, and the tube bundle frame is internally detachably connected with multiple heat exchange tubes;

[0012] As a further description of the above technical solution:

[0013] Each of the heat exchange tubes is slidably connected to a sealing ring, and a baffle is fixedly connected to the outside of the heat exchange tube.

[0014] As a further description of the above technical solution:

[0015] The connecting rod is slidably connected to the inside of the housing, and the outside of the limiting block is engaged with the inside of the limiting groove;

[0016] As a further description of the above technical solution:

[0019] The outer side of the baffle is in contact with the outside of the tube bundle frame, and the outer side of the sealing ring is in contact with the inside of the tube bundle frame.

[0020] This utility model has the following beneficial effects:

[0021] In this invention, the connecting rod is rotated by rotating the rotating plate, thereby causing the limiting block to disengage from the limiting groove, so that the tube bundle frame can be directly pulled out of the shell, thus achieving the effect of quick disassembly without disassembling the entire heat exchanger structure. The tube bundle frame can be removed and a single heat exchange tube can be replaced, which facilitates the replacement or maintenance of internal heat exchange tubes, greatly shortens maintenance time, and reduces equipment downtime losses.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 2 to 4 This utility model provides an embodiment of a heat pipe structure for a heat exchanger, including a shell 1, which serves as the basic framework for the entire heat pipe structure, providing installation space and support for internal components. A tube bundle frame 5 is slidably connected inside the shell 1, serving as the mounting carrier for heat exchange tubes 6. Multiple connecting rods 9 are rotatably connected inside the shell 1, allowing for the fixing and releasing of the tube bundle frame 5 through rotation. Rotating plates 10 are fixedly connected to the outside of each connecting rod 9, facilitating manual rotation by the operator to drive the connecting rods 9. Two limiting plates are provided on the outside of each connecting rod 9. The slot 11, which cooperates with the limiting block 15, is a key structure for fixing the tube bundle frame 5. Multiple sliders 12 are slidably connected inside the housing 1 to transmit power and compress the springs 13. Springs 13 are fixedly connected to the far side of two sliders 12 to provide reset power for the limiting block 15. Connecting rods 14 are fixedly connected to the near side of two sliders 12 to transmit force. Limiting blocks 15 are fixedly connected to the near side of two connecting rods 14. The outside of the connecting rods 14 engages with the inside of the limiting slot 11, which is a key actuator for fixing the tube bundle frame 5.

[0030] Reference Figure 1 and Figure 2Two heat exchange heads 2 are detachably connected to the outside of the shell 1, transferring heat to the heat exchange tubes 6 inside the shell 1. Multiple fixing plates 3 are fixedly connected to both the heat exchange heads 2 and the outside of the shell 1, secured by bolts 4, providing a stable connection. Bolts 4 are threadedly connected inside the fixing plates 3, cooperating with them to achieve a tight connection between the heat exchange heads 2 and the shell 1. Multiple heat exchange tubes 6 are detachably connected inside the tube bundle frame 5, facilitating replacement of any faulty heat exchange tube 6. Sealing rings 7 are slidably connected to the outside of each heat exchange tube 6, contacting the inside of the tube bundle frame 5 to provide a seal and prevent leakage of the medium during heat exchange. Baffles 8 are fixedly connected to the outside of each heat exchange tube 6. The sealing ring 7 is compressed to ensure the airtightness between the heat exchange tube 6 and the tube bundle frame 5. The external sliding connection of the connecting rod 14 is inside the housing 1, and it slides inside the housing 1 to transmit force. The external engagement of the limiting block 15 with the internal engagement of the limiting groove 11 enables the fixing and disassembly of the tube bundle frame 5. The external sliding connection of the limiting block 15 is inside the housing 1. The rotation of the connecting rod 9 will compress the limiting block 15, thereby causing the limiting block 15 to slide into the housing 1. The external rotatable connection of the connecting rod 9 is inside the tube bundle frame 5, and the tube bundle frame 5 is fixed and disassembled by rotation. The external contact connection of the baffle 8 is outside the tube bundle frame 5 to compress and fix the sealing ring 7. The external contact connection of the sealing ring 7 is inside the tube bundle frame 5 to ensure the airtightness between the heat exchange tube 6 and the tube bundle frame 5 and prevent leakage.

[0031] Working principle: When heat pipe replacement is required, rotating the rotating plate 10 drives the connecting rod 9 to rotate, which in turn squeezes the limiting block 15 through its inclined opening. This, in turn, compresses the spring 13 through the connecting rod 14 and the slider 12, causing the limiting block 15 to slide into the housing 1. The limiting block 15 is then pulled upwards, allowing the connecting rod 9 to leave the tube bundle frame 5, thus enabling the tube bundle frame 5 to be disassembled. This allows for the replacement and maintenance of the heat exchange tube 6, achieving a quick disassembly. For installation, the tube bundle frame 5, along with the heat exchange tube 6, is placed in. The rotating plate 10 rotates, causing the connecting rod 9 to squeeze the limiting block 15. When the limiting block 15 aligns with the groove 11, the spring 13 rebounds, locking the limiting block 15 into the groove 11 for fixation. This eliminates the need to disassemble the entire heat exchanger structure. The tube bundle frame 5 can be removed for individual heat exchange tube 6 replacement, facilitating the replacement or maintenance of the internal heat exchange tube 6, significantly reducing maintenance time and minimizing equipment downtime losses.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
