Three-dimensional rotational flow enhanced heat exchange device

Abstract

The utility model relates to the technical field of heat exchange devices, in particular to a three-dimensional rotational flow enhanced heat exchange device which comprises a three-dimensional rotational flow enhanced heat exchanger body and a protective box fixedly installed on the outer wall of the three-dimensional rotational flow enhanced heat exchanger body, and adjusting mechanisms are arranged in the middles of an upper wall plate and a lower wall plate of the protective box. The two adjusting mechanisms are symmetrically designed with respect to the center of the protection box body. Through the arrangement of the ventilation long hole and the filter screen, when the internal temperature of the protection box body exceeds the highest threshold value set by the temperature sensor, the electric telescopic rod shrinks to drive the magnetic suction frame to move to expose the ventilation long hole, and when the internal temperature of the protection box body is lower than the lowest threshold value set by the temperature sensor, the magnetic suction frame moves to expose the ventilation long hole. The electric telescopic rod stretches out and draws back to drive the filter screen on the magnetic suction frame to move to block the ventilation long hole, and coordination and unification of ventilation and dustproof requirements are achieved.

Description

Technical Field

[0001] This utility model relates to the field of heat exchange device technology, specifically a three-dimensional swirling enhanced heat exchange device. Background Technology

[0002] With the impact of global climate change and human activities, the melting of permafrost has become a serious environmental problem, affecting infrastructure construction and human life in many regions. The three-dimensional vortex enhanced heat exchange device is a device used to improve heat exchange efficiency, especially suitable for the cooling needs caused by the melting of permafrost. Its core design lies in the optimized combination of spiral structure and three-dimensional vortex to significantly enhance the heat exchange process. The optimized design of the spiral structure, through continuous gradual pitch, makes the upper pitch smaller and the lower pitch larger, which can effectively match the temperature gradient of the permafrost and achieve more precise heat exchange.

[0003] In the field of permafrost thawing and utilization, three-dimensional swirling enhanced heat exchangers are usually installed in specially designed enclosures to resist external mechanical damage, harsh environmental corrosion, and other adverse factors. However, in actual operation, it is difficult to coordinate the ventilation and dust prevention requirements inside the enclosure. On the one hand, the heat exchanger generates a large amount of heat during operation, requiring an efficient ventilation and heat dissipation system to maintain internal airflow circulation and prevent excessive temperature from causing performance degradation. On the other hand, an overly open ventilation design allows a large amount of dust, particles, and other pollutants to enter the enclosure, adhere to the surface of the heat exchanger, reduce heat transfer efficiency, and even cause equipment failure. To address this, we propose a three-dimensional swirling enhanced heat exchange device. Utility Model Content

[0004] The purpose of this invention is to provide a three-dimensional swirling enhanced heat exchange device to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A three-dimensional swirling enhanced heat exchange device includes a three-dimensional swirling enhanced heat exchanger body and a protective box fixedly installed on the outer wall of the three-dimensional swirling enhanced heat exchanger body. An adjustment mechanism is provided in the middle of the upper and lower wall plates of the protective box, and the two adjustment mechanisms are symmetrically designed about the center of the protective box.

[0007] Preferably, the adjustment mechanism includes two mounting compartments formed in the inner cavity of the protective box wall panel, and each of the two wall panels of the two mounting compartments, which are far apart from each other, is fixedly equipped with an electric telescopic rod.

[0008] Preferably, each of the four electric telescopic rods has a magnetic frame fixedly installed at its telescopic end, a filter screen is movably attached to the top surface of the frame wall of each of the four magnetic frames, and a magnetic enclosure plate is movably attached to the top surface of the mesh edge of each of the four filter screens.

[0009] Preferably, the bottom of the four magnetic enclosures is magnetically attracted to the top of the four magnetic frames, and the bottom wall panels of the two installation compartments are provided with multiple ventilation holes for ventilation and heat dissipation, and the filter screen is used to block the ventilation holes.

[0010] Preferably, the inner cavities of the four side walls of the protective enclosure are also fixedly installed with glass wool for heat insulation and flame retardancy.

[0011] Preferably, mounting plates are fixedly connected to both sides of the bottom surface of the protective box, and threaded holes for mounting the device are opened at both ends of the two mounting plates.

[0012] Preferably, one side wall panel of the protective enclosure is provided with a plug-in slot for inspecting the body of the three-dimensional vortex enhanced heat exchanger. The inner cavity of the plug-in slot is movably connected to a mounting frame for sealing the plug-in slot. A glass plate for observing the internal condition of the protective enclosure is fixedly installed on the inner frame surface of the mounting frame.

[0013] Preferably, multiple negative pressure fans for accelerating heat dissipation from the three-dimensional swirling enhanced heat exchanger body are fixedly installed at the two ventilation holes in the adjustment mechanism at the top wall panel of the protective box.

[0014] Preferably, a temperature sensor for detecting the internal temperature of the protective box is fixedly installed on the side wall away from the insertion slot of the inner cavity of the protective box, and a controller for controlling the operation of the electric telescopic rod is also fixedly installed on the side wall away from the insertion slot of the inner cavity of the protective box.

[0015] Preferably, the temperature sensor, controller, negative pressure fan, and electric telescopic rod are connected by communication.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model, through the design of ventilation holes and a filter screen, allows the temperature sensor to transmit a signal to the controller when the internal temperature of the protective chamber exceeds the maximum threshold set by the temperature sensor. Upon receiving the signal, the controller activates the negative pressure fan and the electric telescopic rod. The retraction of the electric telescopic rod moves the magnetic frame to expose the ventilation holes, which, in conjunction with the negative pressure fan, accelerates the heat dissipation of the three-dimensional vortex enhanced heat exchanger. When the internal temperature of the protective chamber falls below the minimum threshold set by the temperature sensor, the temperature sensor transmits a signal to the controller. Upon receiving the signal, the controller activates the electric telescopic rod and shuts off the negative pressure fan. The extension and retraction of the electric telescopic rod moves the filter screen on the magnetic frame to block the ventilation holes, preventing dust and impurities from entering the protective chamber and damaging the three-dimensional vortex enhanced heat exchanger. This achieves a coordinated balance between ventilation and dust prevention, extends the service life of the three-dimensional vortex enhanced heat exchanger, and enhances the practicality of the device.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4As shown, a three-dimensional swirling enhanced heat exchange device includes a three-dimensional swirling enhanced heat exchanger body 1 and a protective box 2 fixedly installed on the outside of the three-dimensional swirling enhanced heat exchanger body 1. Adjustment mechanisms 3 are provided in the middle of the upper and lower walls of the protective box 2. The two adjustment mechanisms 3 are symmetrically designed about the center of the protective box 2. Each adjustment mechanism 3 includes two installation chambers 31 opened in the inner cavity of the protective box 2 wall. Electric telescopic rods 32 are fixedly installed on the two mutually spaced walls of the inner cavities of the two installation chambers 31. Magnetic frames 33 are fixedly installed at the telescopic ends of the four electric telescopic rods 32. Filter screens 34 are movably attached to the top surface of the frame walls of the four magnetic frames 33. Magnetic retaining plates 35 are movably attached to the top surface of the mesh edges of the four filter screens 34. The bottom of the four magnetic retaining plates 35 is magnetically attracted to the top of the four magnetic frames 33. Multiple long ventilation holes 36 for ventilation and heat dissipation are opened on the bottom wall of each of the two installation chambers 31. The filter screens 34 are used to block the long ventilation holes 36.

[0026] In practice, when the three-dimensional vortex enhanced heat exchanger body 1 is idle, the magnetic suction frame 33 is moved by the telescopic end of the electric telescopic rod 32. The magnetic suction frame 33 in the two installation chambers 31 magnetically attracts the filter screen 34 on the magnetic suction frame 33 to block the ventilation hole 36, preventing dust and impurities from entering the protective box 2 through the ventilation hole 36 and damaging the three-dimensional vortex enhanced heat exchanger body 1. When the temperature of the three-dimensional vortex enhanced heat exchanger body 1 is too high and the pores of the filter screen 34 cannot meet the heat dissipation of the three-dimensional vortex enhanced heat exchanger body 1, the ventilation hole 36 can be completely exposed for ventilation by adjusting the telescopic end of the electric telescopic rod 32 to move the magnetic suction frame 33, thereby accelerating the cooling of the three-dimensional vortex enhanced heat exchanger body 1.

[0027] By removing the magnetic enclosure 35 from the magnetic frame 33, the filter screen 34 can be disassembled, making it easy to clean or replace the filter screen 34.

[0028] As a technical optimization of this utility model, glass wool for heat insulation and flame retardancy is also fixedly installed in the inner cavity of the four side walls of the protective box 2. Mounting plates 7 are fixedly connected to both sides of the bottom surface of the protective box 2, and threaded holes for installing the device are opened at both ends of the two mounting plates 7.

[0029] In practice, by utilizing the glass wool inside the protective enclosure 2, if the cables inside the protective enclosure 2 unfortunately catch fire, the properties of the glass wool can block the spread of the fire and prevent the fire from becoming too large. The device can be fixed by using the threaded holes on the mounting plate 7 at the bottom of the protective enclosure 2 and connecting bolts.

[0030] As a technical optimization of this utility model, a plug-in slot 4 is provided on one side wall of the protective box 2 for inspecting the three-dimensional vortex enhanced heat exchanger body 1. The inner cavity of the plug-in slot 4 is movably connected to a mounting frame 5 for sealing the plug-in slot 4. A glass plate 6 for observing the internal condition of the protective box 2 is fixedly installed on the inner frame surface of the mounting frame 5. Multiple negative pressure fans 10 for accelerating the heat dissipation of the three-dimensional vortex enhanced heat exchanger body 1 are fixedly installed at the two ventilation holes 36 in the adjustment mechanism 3 at the top wall of the protective box 2.

[0031] In practice, the working status of the equipment inside the protective box 2 can be easily observed through the glass plate 6. By pulling out the mounting frame 5, the three-dimensional vortex enhanced heat exchanger body 1 inside the protective box 2 can be easily maintained and repaired using the plug-in slot 4. By starting the negative pressure fan 10, the negative pressure fan 10 can accelerate the ventilation rate of the protective box 2 and at the same time speed up the cooling of the three-dimensional vortex enhanced heat exchanger body 1, thus enhancing the practicality of the device.

[0032] As a technical optimization of this utility model, a temperature sensor 8 for detecting the internal temperature of the protective box 2 is fixedly installed on the side wall away from the insertion slot 4 in the inner cavity of the protective box 2. A controller 9 for controlling the operation of the electric telescopic rod 32 is also fixedly installed on the side wall away from the insertion slot 4 in the inner cavity of the protective box 2. The temperature sensor 8, controller 9, negative pressure fan 10 and electric telescopic rod 32 are connected by communication.

[0033] In practice, when the internal temperature of the protective enclosure 2 exceeds the maximum threshold set by the temperature sensor 8, the temperature sensor 8 transmits a signal to the controller 9. After receiving the signal, the controller 9 starts the negative pressure fan 10 and the electric telescopic rod 32. The retraction of the electric telescopic rod 32 moves the magnetic frame 33 to expose the ventilation hole 36, which, together with the negative pressure fan 10, accelerates the heat dissipation of the three-dimensional vortex enhanced heat exchanger body 1. When the internal temperature of the protective enclosure 2 is lower than the minimum threshold set by the temperature sensor 8, the temperature sensor 8 transmits a signal to the controller 9. After receiving the signal, the controller 9 starts the electric telescopic rod 32 and shuts down the negative pressure fan 10. The extension and retraction of the electric telescopic rod 32 moves the filter screen 34 on the magnetic frame 33 to block the ventilation hole 36, preventing dust and impurities from entering the protective enclosure 2 and damaging the three-dimensional vortex enhanced heat exchanger body 1.

[0034] When the three-dimensional vortex enhanced heat exchanger body 1 is idle, the telescopic end of the electric telescopic rod 32 drives the magnetic frame 33 to move. The magnetic frames 33 in the two mounting chambers 31 magnetically attract each other, causing the filter screen 34 on the magnetic frames 33 to block the ventilation holes 36. When the internal temperature of the protective housing 2 exceeds the maximum threshold set by the temperature sensor 8, the temperature sensor 8 transmits a signal to the controller 9. Upon receiving the signal, the controller 9 activates the negative pressure fan 10 and the electric telescopic rod 32. The retraction of the electric telescopic rod 32 moves the magnetic frame 33, exposing the ventilation holes 36, which, in conjunction with the negative pressure fan... 10. To accelerate the heat dissipation of the three-dimensional vortex enhanced heat exchanger body 1, when the internal temperature of the protective box 2 is lower than the minimum threshold set by the temperature sensor 8, the temperature sensor 8 transmits a signal to the controller 9. After receiving the signal, the controller 9 starts the electric telescopic rod 32 and shuts off the negative pressure fan 10. The electric telescopic rod 32 extends and retracts, driving the magnetic suction frame 33 to move and block the ventilation hole 36. When the filter screen 34 needs to be replaced, the filter screen 34 can be disassembled and replaced by removing the magnetic suction plate 35 on the magnetic suction frame 33. By pulling out the installation frame 5, it is convenient to perform maintenance on the three-dimensional vortex enhanced heat exchanger body 1 inside the protective box 2.
