Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to an adjustable flow heat exchanger. Background Technology

[0002] Heat exchangers, as indispensable core equipment in the heat energy conversion process, are widely used in various industrial fields such as chemical, HVAC, food, and energy. Their basic function is to achieve heat exchange between two media at different temperatures to achieve purposes such as temperature regulation, energy recovery, or production process control. With the diversification of operational needs in industrial plants and the increasing complexity of heat exchange conditions, higher requirements are placed on the heat transfer efficiency, energy consumption control, and adaptability of heat exchangers.

[0003] In existing technologies, heat exchangers typically employ fixed inlet and outlet piping in conjunction with internal heat exchange units to transfer heat. Common internal heat exchange elements include plate, shell-and-tube, and spiral types, achieving heat exchange by controlling the temperature difference between the inlet and outlet of the heat medium. Their structure is primarily rigid piping, and the flow rate of the hot fluid depends on a stable supply from the upstream piping network or external valve control, lacking the ability to fine-tune the flow rate within the equipment itself. Especially in devices where heat exchange demands change frequently, this fixed flow rate design makes it difficult to respond quickly, affecting overall heat exchange efficiency.

[0004] In existing heat exchanger structures, the flow regulation mechanism relies on external piping devices or fixed structures, making it difficult to quickly adjust the inlet water flow according to instantaneous operating conditions during actual operation. This results in unstable heat exchange efficiency due to a fixed inlet water flow. The lack of flexible flow control methods makes existing heat exchangers poorly adaptable, with low energy utilization, and unable to meet the requirements of modern industrial applications that demand high energy efficiency, high performance, and dynamic response capabilities. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable flow heat exchanger, which aims to improve the problem that the existing heat exchanger has insufficient flow regulation capability, resulting in unstable heat exchange efficiency, high energy consumption or insufficient heat exchange due to the fixed inlet water flow.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable flow heat exchanger, comprising an inlet pipe, a connecting ring 1 sleeved on the outer wall of the inlet pipe, a connecting ring 2 fixedly connected to the outer wall of the connecting ring 1, a slide rail 1 fixedly connected to the outer wall of the connecting ring 1, a slider slidably connected to the inner wall of the slide rail 1, a lead screw 2 fixedly connected to the outer wall of the slider, and an adjustment component provided inside the connecting ring 1;

[0007] The regulating assembly includes a baffle plate disposed inside a connecting ring.

The baffle plate is slidably connected to the inner wall of the slide rail. Another connecting rod is rotatably connected to the outer wall of the baffle plate, and a half gear is fixedly connected to the outer wall of the connecting rod. The half gears mesh with each other.

[0008] Furthermore, a cap is fixedly connected to the outer wall of the water inlet pipe, a shell is fixedly connected to the outer wall of the cap, a heat exchange tube is fixedly connected to the outer wall of the shell, a sealing ring one and a sealing ring two are sleeved on the outer wall of the heat exchange tube, a connecting block is fixedly connected to the outer wall of both the sealing ring one and the sealing ring two, a screw rod one is threadedly connected to the inner wall of the connecting block, a sealing ring one is fixedly connected to the outer wall of the heat exchange tube, a joint is fixedly connected to the outer wall of the heat exchange tube, a sealing ring two is fixedly connected to the outer wall of the joint, and a sealing gasket is attached to the outer wall of the sealing ring one.

[0009] Furthermore, a reinforcing ring is fixedly connected to the outer wall of the shell, and a water outlet pipe is fixedly connected to the outer wall of the shell.

[0010] Furthermore, a base is fixedly connected to the outer wall of the housing, and the sealing ring is disposed on the inner wall of the sealing ring.

[0011] Furthermore, one end of the connecting rod is disposed on the inner wall of the slider, and a lead screw is threadedly connected to the inner wall of the slide rail.

[0012] Furthermore, one end of the connecting rod is rotatably connected to the inner wall of the slide rail, and the other end of the connecting rod is fixedly connected to the inner wall of the baffle plate.

[0013] Furthermore, the flow-blocking plate is slidably connected to the inner wall of the first connecting ring, and the second connecting ring is disposed on the inner wall of the water inlet pipe.

[0014] Furthermore, the sealing gasket is disposed inside the first sealing ring, and the sealing gasket is in contact with the second sealing ring.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, a connecting ring is set outside the water inlet pipe, and a slide rail and a slider are provided on it. The slider and the lead screw are linked to drive the internal baffle plate to slide in the slide rail. The linkage mechanism drives the two baffle plates to adjust their positions in coordination, thereby changing the effective area of ​​the water inlet channel and achieving precise regulation of the water inlet flow. This structure overcomes the problem that the water inlet flow of the existing heat exchanger is fixed and cannot flexibly cope with changes in operating conditions, and significantly improves the matching ability and thermal efficiency of the heat exchanger under different operating conditions.

[0017] 2.

The sealing ring I is embedded in the inner wall of the sealing ring, and the sealing gasket is placed between the sealing ring I and the sealing ring II. The gasket has a circular shape in the middle and a flat structure on both sides, which fits the outer wall of the sealing ring II. It can fully cover the connection gap and form a stable sealing interface during the connection of the pipe fittings. This effectively prevents the medium from leaking due to thermal expansion and contraction, vibration, or loosening of the interface, thereby enhancing the sealing integrity and reliability of the entire heat exchanger device.

The sealing gasket 26 is attached to the sealing ring 27.

[0029] Working Principle: When an adjustable flow heat exchanger is needed, liquid first enters the shell 2 through the inlet pipe 7 and flows laterally inside. Another liquid enters the shell 2 through the heat exchange pipe 8 and flows linearly along the pipe. Heat exchange occurs between the two fluids inside the shell 2, transferring heat from the high-temperature fluid to the low-temperature fluid. Finally, the liquid is discharged from the outlet pipe 9. When flow rate adjustment is required, connecting ring 5 is installed on the outer wall of the inlet pipe 7. A slide rail 14 is installed on the outer wall of connecting ring 5. A slider 16 slides on the inner wall of slide rail 14. A lead screw 17 is fixed on the outer wall of slider 16. Rotating the lead screw 17 causes slider 16 to slide between slide rails 14. Two flow baffles 18 are installed inside connecting ring 5. The baffle plate 18 can slide along the slide rail 20 to adjust its position within the cross section of the inlet pipe 7. The baffle plate 18 is connected to the slider 16 via the connecting rod 15. The movement of the slider 16 can drive the connecting rod 15 to move the baffle plate 18 linearly. The baffle plate 18 is connected to the first half gear 22 and the second half gear 23 via the first connecting rod 19 and the second connecting rod 21, respectively. The two mesh with each other, so that the baffle plate 18 can slide together during the adjustment process to adjust the effective area of ​​the fluid channel, thereby controlling the inlet water flow. By manually or automatically rotating the screw 17, the position of the baffle plate 18 can be finely adjusted, thereby accurately controlling the inlet water flow and improving the adaptability and energy efficiency of the heat exchanger under different operating conditions.

[0030] In addition, the connection between the water inlet pipe 7 and the connector 24 is equipped with a multi-seal structure. The end cap 4 is fixedly connected to the outer wall of the water inlet pipe 7, and the heat exchange tube 8 is fixedly connected to the outer wall of the shell 2. The outer wall of the heat exchange tube 8 is fitted with a sealing ring 10 and a sealing ring 11. Both the sealing ring 10 and the sealing ring 11 are provided with connecting blocks 12 on their outer walls. The inner wall of the connecting block 12 is threaded with a screw rod 13. The sealing ring clamping force can be adjusted by rotating the screw rod 13 to enhance the sealing contact. The outer wall of the heat exchange tube 8 is provided with a sealing ring 25 and a sealing gasket 26 in sequence. The sealing ring 25 has a groove inside that matches the sealing gasket 26. The middle part is a circular ring, and the two sides are flat. The sealing gasket 26 is attached to the outer wall of the sealing ring 27, effectively sealing the gap between the joint 24 and the pipe body, avoiding medium leakage caused by thermal expansion and contraction, mechanical vibration or loose connection. The sealing ring 25 is embedded in the inner wall of the sealing ring 10, which plays a buffering and limiting role, further improving the sealing integrity. This sealing structure has multi-level protection and structural redundancy, ensuring the interface sealing performance of the heat exchanger during continuous high load operation, effectively extending the service life of the equipment, reducing the frequency of maintenance and operating risks, and improving the safety and reliability of the whole machine operation.
