Description

Technical Field

[0001] This utility model relates to the technical field of heat exchanger units, specifically a multi-stage efficiency heat exchanger unit. Background Technology

[0002] A multi-stage heat exchanger unit is a heat exchange equipment system composed of multiple heat exchangers connected in series or in parallel in a certain way. It aims to achieve the transfer of heat between different media more efficiently through a multi-stage heat exchange process to achieve specific heating, cooling or energy recovery effects. It usually includes multiple heat exchangers of different or the same type, such as plate heat exchangers and shell and tube heat exchangers, as well as supporting equipment such as pipes, valves, pumps, and control systems, which work together to complete the multi-stage transfer and conversion of heat.

[0003] The applicant believes that:

[0004] Even with good insulation, some heat will still be conducted to the surrounding environment through the heat exchanger shell when the heat exchanger unit is in operation. If heat cannot be effectively prevented from dissipating into the surrounding environment, the heat that could have been used to heat or cool the target fluid will be lost to the surrounding air, resulting in inefficient energy utilization, energy waste, and increased energy consumption costs. At the same time, the heat dissipated into the surrounding environment will raise the local temperature around the heat exchanger unit, which may affect the normal operation of surrounding equipment and instruments, shorten their service life, and may also damage some temperature-sensitive materials or items, thus requiring improvement. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a multi-stage heat exchanger unit that can absorb and utilize the heat emitted by the heat exchanger unit. This solves the problem that if heat cannot be effectively prevented from dissipating into the surrounding environment, the heat that could have been used to heat or cool the target fluid will be wasted in the surrounding air, resulting in inefficient energy utilization, energy waste, and increased energy consumption costs. At the same time, heat dissipation into the surrounding environment will cause the local temperature around the heat exchanger unit to rise, which may affect the normal operation of surrounding equipment and instruments, shorten their service life, and may also damage some temperature-sensitive materials or items.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage heat exchanger unit, comprising a base plate, a heat exchanger unit body, and a heat exhaust component. The heat exchanger unit body is installed inside the base plate, and the heat exhaust component is arranged above the base plate. The heat exhaust component includes a frame, a slide rail, a pulley, a tie rod, a folding isolation cover, a threaded cylinder, a threaded rod, an air intake cover, a fan, and a connecting pipe.

[0009] A frame is welded to the four corners of the base plate. Slide rails are connected through both sides of the frame. Pulleys are slidably connected inside the slide rails. A pull rod is fixedly connected to one side of the pulley. A folding isolation cover is fixedly connected above the pull rod on the top plate of the frame. An air suction cover is connected through the top plate of the frame. A fan is installed inside the air suction cover. A connecting pipe is connected to the air outlet of the air suction cover.

[0010] Furthermore, threaded cylinders are welded to both sides of the pull rod, and threaded rods are threadedly connected to the inside of the threaded cylinders.

[0011] Furthermore, a fixing and adjusting component is provided below the base plate. The fixing and adjusting component includes a base, a forklift slot, a moving wheel, a connecting block, a threaded sleeve, a threaded crank handle, a fixing plate, and a fixing hole.

[0012] Furthermore, a base is welded to the bottom of the base plate, and forklift slots are provided on both sides of the front of the base.

[0013] Furthermore, each of the four lower corners of the base is fixedly connected with a movable wheel, and each side of the base is welded with a connecting block.

[0014] Furthermore, a threaded sleeve is internally connected to the other side of the connecting block, and a threaded crank handle is internally connected to the threaded sleeve.

[0015] Furthermore, the lower end of the threaded crank handle is connected to a fixing plate via a bearing, and fixing holes are provided on both sides of the fixing plate.

[0016] Compared with the prior art, this utility model provides a multi-stage efficiency heat exchanger unit, which has the following beneficial effects:

[0017] 1. When the heat exchanger unit is working, the sliding of the pull rod and pulley on the slide rail allows the folding isolation cover to be opened and closed on the frame. This provides a protective enclosure around the frame, preventing the heat emitted by the heat exchanger unit from spreading and affecting surrounding equipment and the working environment. At the same time, the rotation of the fan can draw heat through the suction hood to the connecting pipe for discharge, so that this heat can be transferred to other links that require heat. This improves the energy utilization rate of the entire production process. In addition, removing surrounding heat can keep the equipment within the normal operating temperature range, reduce the impact of high temperature on the performance of equipment materials, extend the service life of equipment materials, and reduce the maintenance and replacement costs of the equipment.

[0018] 2. When the heat exchanger unit is in operation, the combination of the forklift slot and the moving wheels allows the heat exchanger unit to move flexibly on the ground. By rotating the threaded crank handle and engaging the threaded sleeve, the fixing plate can be brought into contact with the ground, providing stable placement and fine-tuning of the base. This ensures more precise and convenient connection with pipes, valves, and other related equipment, reducing installation difficulties and unreasonable pipe connections caused by inaccurate positioning.

[0026] 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 merely 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 6 This utility model provides a technical solution: a multi-stage heat exchanger unit, including a base plate 1, a heat exchanger unit body 2 and a heat exhaust component 3. The heat exchanger unit body 2 is installed inside the upper part of the base plate 1, the heat exhaust component 3 is arranged above the base plate 1, and a fixing and adjusting component 4 is arranged below the base plate 1.

[0028] Specifically: When the heat exchanger unit is working, firstly, the heat exchanger unit body 2 inside the base plate 1 is moved to a suitable position and stably fixed by the fixing and adjusting component 4. Secondly, the heat exchanger unit body 2 is connected to the working pipeline. Then, the heat exchanger unit body 2 completes the multi-stage transfer and conversion of heat to the equipment. When the heat exchanger unit body 2 is working, the heat emitted by the heat exchanger unit body 2 during operation can be discharged and utilized through the heat exhaust component 3.

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4A multi-stage heat exchanger unit includes a heat exhaust component 3 mounted above a base plate 1. The heat exhaust component 3 comprises a frame 301, slide rails 302, pulleys 303, a tie rod 304, a folding isolation cover 305, a threaded cylinder 306, a threaded rod 307, an air intake hood 308, a fan 309, and a connecting pipe 310. Frames 301 are welded to the four corners of the base plate 1. Slide rails 302 are connected through both sides of the frame 301, and pulleys 302 are slidably connected inside the slide rails 302. 03. A pull rod 304 is fixedly connected to one side of the pulley 303. A folding isolation cover 305 is fixedly connected above the pull rod 304 on the top plate of the frame 301. An air suction cover 308 is connected through the top plate of the frame 301. A fan 309 is installed inside the air suction cover 308. A connecting pipe 310 is connected to the air outlet of the air suction cover 308. Threaded cylinders 306 are welded to both sides of the pull rod 304. Threaded rods 307 are threadedly connected inside the threaded cylinders 306.

[0030] Specifically, when the heat dissipation component 3 dissipates the heat emitted by the heat exchanger unit 2 during operation, the connecting pipe 310 is first connected to the pipe requiring heat utilization. Next, the pull rod 304, in conjunction with the pulley 303, slides on the slide rail 302, causing the pull rod 304 to drive the folding isolation cover 305 to close on the frame 301. Then, the threaded rod 307, in conjunction with the threaded cylinder 306, fixes the pull rod 304, thereby providing a protective enclosure around the frame 301, preventing the heat emitted by the heat exchanger unit 2 from spreading and affecting surrounding equipment and the working environment. Simultaneously, the rotation of the fan 309 draws heat through the suction hood 308 to the connecting pipe 310 for discharge, facilitating the transfer of this heat to other stages requiring heat. This improves the energy utilization rate of the entire production process. Furthermore, removing surrounding heat keeps the equipment within its normal operating temperature range, reducing the impact of high temperatures on equipment material properties, extending the service life of equipment materials, and lowering equipment maintenance and replacement costs.

[0031] Please see Figure 1 , Figure 5 and Figure 6A multi-stage heat exchanger unit includes a fixed adjustment component 4 comprising a base 401, a forklift slot 402, a caster wheel 403, a connecting block 404, a threaded sleeve 405, a threaded crank handle 406, a fixing plate 407, and fixing holes 408. The base 401 is welded to the bottom of the base plate 1. Forklift slots 402 are provided on both sides of the front of the base 401. Caster wheels 403 are fixedly connected to the four corners of the bottom of the base 401. Connecting blocks 404 are welded to both sides of the base 401. A threaded sleeve 405 is internally connected to the other side of the connecting block 404. A threaded crank handle 406 is threadedly connected to the inside of the threaded sleeve 405. The lower end of the threaded crank handle 406 is connected to the fixing plate 407 via a bearing. Fixing holes 408 are provided on both sides of the fixing plate 407.

[0032] Specifically: When the fixed adjustment component 4 moves the heat exchanger unit body 2 to a suitable position for stable fixing, firstly, the forklift forks are inserted into the forklift slot 402. Secondly, the forklift drives the base 401 to move and place the heat exchanger unit body 2 to a suitable position. Then, with the help of the moving wheels 403, the base 401 is finely adjusted, which allows the heat exchanger unit to move flexibly on the ground. By rotating the threaded handle 406 and cooperating with the threaded sleeve 405, the fixing plate 407 can be brought into contact with the ground, providing the base 401 with stable placement and fine-tuning functions. This ensures that its connection with pipes, valves and other related equipment is more accurate and convenient, reducing installation difficulties and unreasonable pipe connections caused by inaccurate positioning. Finally, the fixing bolts are screwed into the fixing holes 408 of the fixing plate 407 to fix the base 401.

[0033] The working principle of this utility model is as follows: When the heat exchanger unit is working, firstly, the forklift forks are inserted into the forklift slot 402. Then, the forklift moves the base 401 to a suitable position. Subsequently, the base 401 is finely adjusted using the moving wheels 403. Next, the threaded crank handle 406, in conjunction with the threaded sleeve 405, brings the fixing plate 407 into contact with the ground, stabilizing the base 401 and allowing for fine-tuning of its height. Finally, the fixing bolts are screwed into the fixing holes 408 of the fixing plate 407 to secure the base 401. Then, the heat exchanger unit 2 is connected to the working pipeline. The heat exchanger unit 2 then completes the multi-stage transfer and conversion of heat from the equipment. Furthermore, when the heat exchanger unit 2 is working... The connecting pipe 310 can be connected to the pipe that requires heat. Then, the pull rod 304 and pulley 303 slide on the slide rail 302, so that the pull rod 304 drives the folding isolation cover 305 to close on the frame 301. Then, the threaded rod 307 and threaded cylinder 306 are used to fix the pull rod 304, thereby covering and isolating the frame 301. Then, the fan 309 is started to rotate, which can draw heat through the suction cover 308 to the connecting pipe 310 for discharge and guidance, and transfer this heat to other links that require heat. In this way, the working principle and process of a multi-stage heat exchanger unit are completed. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
