Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a novel heat exchanger. Background Technology

[0002] Heat exchangers, as core equipment for heat transfer, are widely used in petrochemical, power, metallurgy, refrigeration, aerospace and other fields. Their performance directly affects energy utilization efficiency and system operating costs. Although traditional heat exchangers (such as shell and tube, plate, and finned tube types) are technologically mature, they still face problems such as low heat transfer efficiency, high flow resistance, poor material adaptability, and severe scaling in high-parameter operating conditions (such as high temperature and high pressure, microscale heat transfer, and high-viscosity fluids) or special application scenarios (such as waste heat recovery and electronic device cooling).

[0003] During the use of a heat exchanger, the gas that needs to be heated is transported through heat exchange tubes. During the transport process, due to the lack of an effective flow rate regulation mechanism, when the gas flow rate is too fast, the contact time between the gas and the heat exchange tube wall is insufficient, resulting in incomplete heat exchange and a significant reduction in heat exchange efficiency. On the other hand, when the flow rate is too slow, although the contact time can be extended, the overall heat exchange rate will be reduced, affecting the working efficiency of the system. Utility Model Content

[0004] The purpose of this invention is to provide a novel heat exchanger to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model proposes a novel heat exchanger, including a heat exchanger shell, a heat exchange tube disposed inside the heat exchanger shell, a flow rate control mechanism disposed on one side of the heat exchanger shell, and a magnetic attraction mechanism disposed at one end of the flow rate control mechanism.

[0006] The flow rate control mechanism includes two air pipes fixedly connected to one end of the heat exchange tube. Both ends of the outer walls of the two air pipes are fixedly connected to a fixing ring. A support frame is fixedly connected between the two fixing rings. Both ends of the outer walls of the two air pipes are fixedly connected to an air inlet pipe. One end of the outer wall of the two air inlet pipes is fixedly connected to a branch pipe. The inner walls of the two branch pipes are slidably connected to a movable block. One end of the two movable blocks is fixedly connected to a partition.

[0007] In one example, a gear is rotatably connected to the center of one side of the support frame, and racks are meshed on both sides of the outer wall of the gear. One end of each rack is fixedly connected to a first connecting rod, and the other end of the first connecting rod is fixedly connected to the other end of the movable block.

[0008] In one example, both ends of one side of the support frame are provided with strip grooves, and one side of each of the two racks is fixedly connected with a slider, which is slidably connected to the inner wall of the strip groove.

[0009] In one example, a servo motor is fixedly connected to the center of the other side of the support frame, and the drive shaft of the gear is fixedly connected to the output end of the servo motor.

[0010] In one example, the magnetic attraction mechanism includes a first flange fixedly connected to the other end of two air inlet pipes, a second flange on one side of each of the two first flanges, a round pipe fixedly connected to the other side of each of the two second flanges, a support rod fixedly connected to one side of the inner wall of each of the two round pipes, and a magnetic rod fixedly connected to one side of each of the two support rods.

[0011] In one example, an intelligent control panel is provided on one side of the heat exchanger housing, and a servo motor switch is provided on the surface of the intelligent control panel. The servo motor is electrically connected to an external power source through the servo motor switch.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. A gas pipe is installed on one side of the heat exchange tube, with an inlet pipe at one end of each pipe. The function of the inlet pipe is to facilitate the flow and exchange of gas inside. Branch pipes are installed outside both inlet pipes, and movable blocks are installed inside each branch pipe. A baffle is installed at one end of each movable block, located inside the two inlet pipes. During use, a gear is installed on one side of the support frame. The rotation of the gear drives the racks on both sides to move up and down. A first connecting rod is connected to one end of each rack, and the other end of the first connecting rod is connected to the other end of each movable block. Thus, as the racks move, they pull the movable blocks on both sides to move as well, thereby moving the baffles located inside the inlet pipes. The size of the baffle extending into the inlet pipe controls the gas flow rate inside the inlet pipe. Therefore, during use, the gas flow rate can be controlled by adjusting the size of the baffle, thereby controlling the gas flow rate throughout the heat exchange tube. This allows for heat exchange of the gas for a corresponding time as needed, improving the heat exchange efficiency of the device.

[0014] 2. A first flange is provided on one side of the two air inlet pipes, a second flange is provided on one side of the first flange, and a round pipe is provided on one side of the second flange. The magnetic rod on one side of the support rod inside the round pipe can attract iron filings inside the gas, thereby preventing internal impurities from damaging the inner wall of the heat exchange tube and improving the service life of the heat exchange tube during use.

[0021] 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.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a novel heat exchanger, including a heat exchanger shell 1, a heat exchange tube 2 inside the heat exchanger shell 1, a flow rate control mechanism 3 on one side of the heat exchanger shell 1, and a magnetic attraction mechanism 4 at one end of the flow rate control mechanism 3.

[0023] The flow rate control mechanism 3 includes two air pipes 301 that are fixedly connected to one end of the heat exchange tube 2. Both ends of the outer wall of the two air pipes 301 are fixedly connected to a fixing ring 302. A support frame 303 is fixedly connected between the two fixing rings 302. Both ends of the outer wall of the two air pipes 301 are fixedly connected to an air inlet pipe 304. One end of the outer wall of the two air inlet pipes 304 is fixedly connected to a branch pipe 305. The inner wall of the two branch pipes 305 is slidably connected to a movable block 306. One end of the two movable blocks 306 is fixedly connected to a partition plate 307.

[0024] A gear 308 is rotatably connected to the center of one side of the support frame 303. Both sides of the outer wall of the gear 308 are meshed with racks 309. One end of each rack 309 is fixedly connected to a first connecting rod 310, and the other end of the first connecting rod 310 is fixedly connected to the other end of the movable block 306.

[0025] In use, an air pipe 301 is installed on one side of the heat exchange tube 2. An air inlet pipe 304 is provided at one end of each air pipe 301. The function of the air inlet pipe 304 is to facilitate the exchange of internal gas. A branch pipe 305 is provided outside each of the two air inlet pipes 304. A movable block 306 is provided inside each branch pipe 305, and a partition plate 307 is provided at one end of each of the two movable blocks 306. The partition plate 307 is located inside the two air inlet pipes 304, allowing for the operation of the system. A gear 308 is provided on one side of the support frame 303. The rotation of the gear 308 drives the racks 309 on both sides to move up and down. A first connecting rod 310 is connected to one end of each rack 309. The other end of the connecting rod 310 is connected to the other end of the movable block 306. As the rack 309 moves, it pulls the movable blocks 306 on both sides to move as well. This causes the baffle 307 inside the air inlet pipe 304 to move. The size of the baffle 307 extending into the air inlet pipe 304 can control the gas flow rate inside the air inlet pipe 304. Therefore, during use, the gas flow rate can be controlled by the size of the baffle 307, thereby controlling the gas flow rate inside the entire heat exchange tube 2. This allows for heat exchange of the gas for a corresponding time as needed, improving the heat exchange efficiency of the device during the heat exchange process.

[0026] Furthermore, both ends of one side of the support frame 303 are provided with strip grooves 311, and one side of each of the two racks 309 is fixedly connected with a slider 312, and the slider 312 is slidably connected to the inner wall of the strip groove 311.

[0027] A servo motor 313 is fixedly connected to the center of the other side of the support frame 303, and the drive shaft of the gear 308 is fixedly connected to the output end of the servo motor 313.

[0028] The strip groove 311 provided on one side of the support frame 303, combined with the internal slider 312, can serve as a limit for the rack 309, preventing the rack 309 from falling off during sliding. The servo motor 313 located on the other side of the support frame 303 serves as the drive component of the entire part, and can control the flow rate control mechanism 3.

[0029] Furthermore, the magnetic attraction mechanism 4 includes a first flange 401 fixedly connected to the other end of the two air inlet pipes 304, a second flange 402 provided on one side of each of the two first flanges 401, a round pipe 403 fixedly connected to the other side of each of the two second flanges 402, a support rod 404 fixedly connected to one side of the inner wall of each of the two round pipes 403, and a magnetic rod 405 fixedly connected to one side of each of the two support rods 404.
