Abstract
Description
Technical Field
[0001] This application relates to the field of mine heat dissipation equipment technology, and more specifically, to a heat dissipation device with temperature compensation function for coal mine electromechanical applications. Background Technology
[0002] Currently, most coal mine electromechanical equipment cooling technologies employ fans or circulating liquid cooling. While widely used, these methods have significant drawbacks. During equipment operation, the heat generated is not constant but gradually increases with load variations. Traditional cooling devices typically maintain their initial cooling capacity and cannot dynamically adjust based on real-time equipment temperature. This results in insufficient cooling under high loads and energy waste under low loads, leading to a mismatch between cooling efficiency and equipment heat load. Furthermore, the enclosed and humid environment of underground coal mines means traditional air cooling can easily introduce dust and moisture into the equipment, causing malfunctions or short circuits. Liquid cooling systems, on the other hand, are complex and prone to leakage. Additionally, existing cooling solutions generally lack effective utilization of dissipated heat, resulting in low overall energy efficiency. Therefore, there is an urgent need for an intelligent cooling device that can dynamically compensate for heat dissipation intensity based on equipment temperature, adapt to the harsh underground environment, and achieve efficient energy utilization. This would ensure the stable operation of coal mine electromechanical equipment, extend its service life, and improve energy efficiency. Summary of the Invention
[0003] This application aims to at least address the technical problems in the related technologies, such as the fact that the heat dissipation capacity of traditional heat dissipation devices usually remains in its initial state and cannot be dynamically adjusted according to the real-time temperature of the equipment, and that existing heat dissipation solutions generally lack effective utilization of the dissipated heat, resulting in low overall energy utilization efficiency.
[0004] To solve the above-mentioned technical problems, this application is implemented as follows: This application provides a heat dissipation device with temperature compensation function for coal mine electromechanical equipment, comprising: an insulated box, a top chamber fixedly connected to the upper end of the insulated box, and multiple vortex tubes fixedly connected to the surface of the insulated box, the upper end of the vortex tubes being connected to an air inlet pipe for introducing compressed gas; a heat dissipation mechanism, disposed inside the insulated box, with its upper end extending above the top chamber; the heat dissipation mechanism includes: a cooling component, disposed inside the insulated box and connected to the cold air end of the vortex tubes, for introducing cold airflow into the insulated box and cooling the environment; a regulating compensation component, at least partially disposed inside the cooling component, with its upper end extending into the top chamber, and the thermal conductivity of the regulating compensation component being adjustable to compensate for cooling according to the temperature of the electromechanical equipment; and an exhaust component, disposed above the regulating compensation component and connected to the hot air end of the vortex tubes, for using hot airflow to drive and exhaust the hot air inside the insulated box.
[0005] This application provides a heat dissipation device with temperature compensation function for coal mine electromechanical applications. Through the coordinated operation of cooling, compensation, and exhaust mechanisms, it achieves multiple functions including dynamic temperature control, environmental adaptation, and energy reuse. In dynamic temperature control and efficient heat dissipation scenarios, the cooling mechanism separates compressed gas into cold and hot air streams through multiple annularly distributed vortex tubes. The cold air stream actively cools the environment inside the insulation box and the heat-conducting liquid in the liquid accumulation chamber via cold air pipes wrapped around the inner frame and the surface of the first heat-conducting pipe. This breaks through the limitations of traditional passive heat dissipation and provides a low-temperature basis for temperature compensation. In precise temperature compensation scenarios, the adjustment compensation mechanism drives the central heat-conducting strip to slide within the heat-conducting pipe slide through a pen-type electric push rod, dynamically changing the contact area between the central heat-conducting strip and the second heat-conducting pipe. This allows for stepless adjustment of the cooling power conducted to the surface of the electromechanical equipment by the contact heat-conducting component. When the equipment temperature rises, the contact area increases to enhance heat dissipation and compensate; when the temperature drops, the contact area decreases to avoid overcooling, fundamentally solving the problem of mismatch between heat dissipation capacity and equipment heat load. In scenarios involving energy reuse and efficient air extraction, the extraction mechanism utilizes the typically discarded hot airflow generated by the vortex tube as a power source to drive the arc-shaped plate and rotating ring within the vortex guide seat to rotate, thereby rotating the air guide fan blades and actively extracting and expelling the hot air generated by the equipment from the insulation box. This design not only eliminates the need for additional energy to drive the fan but also achieves the separation and synergistic utilization of hot and cold airflows, significantly improving energy efficiency and overall heat dissipation. In environmentally adaptable scenarios, the spiral inner vortex plate and the trumpet-shaped cold airflow guide plate optimize the guidance and distribution of cold airflow, while the wavy skirt and moisture-absorbing pipe effectively address the condensation that may occur in the high-humidity environment downhole, combining airflow guidance and moisture prevention functions to enhance the reliability of the device.

[0013] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in one embodiment of this application, a heat dissipation device 10 for coal mine electromechanical applications with temperature compensation function includes: an insulated box 100, a top chamber 110 fixedly connected to the upper end of the insulated box 100, a plurality of vortex tubes 200 fixedly connected to the surface of the insulated box 100, and an air inlet pipe for introducing compressed gas connected to the upper end of the vortex tubes 200; a heat dissipation mechanism 300 disposed inside the insulated box 100, and the upper end of the heat dissipation mechanism 300 extending above the top chamber 110; the heat dissipation mechanism 300 includes: a cooling component 310 disposed inside the insulated box 100. The cooling component 310 is connected to the cold air end of the vortex tube 200 and is used to introduce cold air into the insulation box 100 and cool the environment. The regulating compensation component 320 is at least partially disposed inside the cooling component 310. The upper end of the regulating compensation component 320 extends into the top chamber 110 and the thermal conductivity of the regulating compensation component 320 is adjustable to compensate for cooling according to the temperature of the electromechanical equipment. The outlet component 330 is disposed above the regulating compensation component 320 and is connected to the hot air end of the vortex tube 200 to drive and outlet the hot air in the insulation box 100 using hot air.
[0014] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 ,and Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the heat dissipation device 10 for coal mine electromechanical applications with temperature compensation function provided in this application includes an insulated box 100 and a heat dissipation mechanism 300. The upper end of the insulated box 100 is fixedly connected to a top chamber 110, and multiple vortex tubes 200 are fixedly connected to the surface of the insulated box 100. The upper end of each vortex tube 200 is connected to an inlet pipe for introducing high-pressure compressed gas. The heat dissipation mechanism 300 is disposed inside the insulated box 100, and its upper end extends above the top chamber 110. The heat dissipation mechanism 300 includes a cooling component 310, a regulating compensation component 320, and a discharge component 330. The cooling component 310 is disposed inside the insulation box 100 and connected to the cold air end of the vortex tube 200, used to introduce cold airflow into the insulation box 100 and cool the environment. The regulating compensation component 320 is at least partially disposed inside the cooling component 310, with its upper end extending into the top chamber 110. The thermal conductivity of the regulating compensation component 320 is adjustable to compensate for cooling according to the temperature of the electromechanical equipment. The exhaust component 330 is disposed above the regulating compensation component 320 and connected to the hot air end of the vortex tube 200, used to drive and exhaust the hot air inside the insulation box 100 using hot airflow.
[0015] Thus, a complete and efficient heat dissipation system is formed through the heat dissipation mechanism 300 and its internal cooling component 310, regulating and compensating component 320, and exhaust component 330. The vortex tube 200 separates the incoming compressed gas into two streams, cold and hot. The cooling component 310 guides and disperses the cold air stream within the insulation box 100, achieving basic active cooling of the operating environment of the electromechanical equipment. The regulating and compensating component 320, through its adjustable thermal conductivity, can directly respond to the temperature changes of the electromechanical equipment itself, dynamically changing the cooling intensity to achieve precise temperature compensation and avoid overcooling or overheating under fixed heat dissipation capacity. The exhaust component 330 utilizes the previously discarded hot air stream as a power source, driving it to actively extract and discharge the waste heat generated by the equipment from the insulation box 100, forming a closed-loop heat dissipation system. This application utilizes the cold and hot air streams separately and achieves efficient and adaptive heat dissipation for coal mine electromechanical equipment through adjustable temperature compensation, effectively solving the technical problem that traditional heat dissipation devices have fixed heat dissipation capacity and cannot cope with the changing heat load of the equipment.
[0016] Compared with existing technologies, the heat dissipation device 10 for coal mine electromechanical equipment with temperature compensation function provided in this application has the following advantages: First, it forms cold and hot airflows through the vortex tube 200. This device uses the cold airflow injected into the insulation box 100 to change the ambient temperature of the electromechanical equipment, thus assisting in cooling the equipment. Second, it uses the hot airflow to drive the heat dissipation component 330 to assist in dissipating the heat generated by the electromechanical equipment, thereby improving the heat dissipation effect and achieving the functions of cooling and dissipating hot air from the equipment.
[0017] Specifically, coal mine electromechanical equipment refers to the mechanical and electrical equipment used in coal mining, transportation, processing, and sales, playing a crucial role in coal mine production. Maintenance and upkeep of coal mine electromechanical equipment are key to ensuring its normal operation and extending its service life. Specific maintenance measures include general methods such as wiping, cleaning, lubrication, and adjustment. During operation, it is also necessary to mitigate internal overheating to maintain and protect the equipment's performance and technical condition.
[0018] A search of existing technologies revealed that publication number "CN217591457U" discloses "A High-Efficiency Heat Dissipation and Cooling Device for Coal Mine Electromechanical Equipment." This device uses an internally installed motor-driven fan to expel internal heat. However, during operation, the heat dissipation effect of the electromechanical equipment gradually increases, and the device maintains its initial cooling capacity, failing to provide effective heat dissipation during the operation of coal mine electromechanical equipment. In other words, it cannot dynamically adjust its cooling based on the real-time temperature of the equipment.
[0019] To address the shortcomings of existing technologies, the purpose of this application is to resolve the technical problems of traditional heat dissipation devices typically maintaining their initial heat dissipation capacity and being unable to dynamically adjust according to the real-time temperature of the equipment, as well as the general lack of effective utilization of dissipated heat and low overall energy efficiency in existing heat dissipation solutions. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the heat dissipation device 10 for coal mine electromechanical applications with temperature compensation function provided in this application achieves multiple functions such as dynamic temperature control, environmental adaptation, and energy reuse through the coordinated operation of cooling, compensation, and exhaust mechanisms. In the scenario of dynamic temperature control and efficient heat dissipation, the cooling mechanism separates the compressed gas into two airflows, cold and hot, through multiple annularly distributed vortex tubes 200. The cold airflow actively cools the environment inside the insulation box 100 and the heat-conducting liquid in the liquid collection tank 318 via the cold air pipes wrapped around the inner frame 311 and the surface of the first heat-conducting pipe 321, providing a low-temperature basis for temperature compensation. In the scenario of precise temperature compensation, the adjustment compensation mechanism drives the central heat-conducting strip 322 to slide in the heat-conducting pipe slide through the pen-type electric push rod 327, dynamically changing the contact area between the central heat-conducting strip 322 and the second heat-conducting pipe 323, thereby realizing stepless adjustment of the cooling power conducted to the surface of the electromechanical equipment by the contact heat-conducting component 328. When the equipment temperature rises, the contact area is increased to enhance heat dissipation and compensate; when the temperature drops, the contact area is reduced to avoid overcooling, fundamentally solving the problem of mismatch between heat dissipation capacity and equipment heat load. In the scenario of energy reuse and efficient exhaust, the exhaust component 330 uses the normally discarded hot airflow generated by the vortex tube 200 as a power source to drive the arc plate 338 and rotating ring 334 in the cyclone guide seat 332 to rotate, thereby driving the air guide fan blade 337 to rotate, actively extracting and exhausting the hot air generated by the equipment from the insulation box 100. This design does not require additional energy to drive the fan and achieves the diversion and synergistic utilization of hot and cold airflow, significantly improving energy utilization efficiency and overall heat dissipation effect. In the scenario of environmental adaptability, the spiral inner vortex plate 315 and the trumpet-shaped cold airflow guide plate 314 optimize the guidance and distribution of cold airflow, while the wavy skirt and moisture absorption pipe 317 effectively deal with the condensation that may be generated in the high humidity environment downhole, combining airflow guidance and moisture prevention functions, and improving the reliability of the device.
[0020] In practical applications, when using this device, the coal mine electromechanical equipment to be used can be placed inside the insulation box 100, with the equipment located inside the moisture absorption pipe 317. The liquid collection chamber 318 is filled with a heat-conducting liquid, which can be water or other heat-conducting materials, depending on the actual application scenario. High-pressure gas is injected into the vortex pipe 200 through the air inlet pipe, and low-temperature gas is introduced into the second cold air pipe 313 through the vortex pipe 200. Since the second cold air pipe 313 is wrapped around the surface area near the first heat-conducting pipe 321, the liquid temperature inside the liquid collection chamber 318 can be reduced. At the same time, the first cold air pipe 312 wrapped around the middle of the inner frame 311 can reduce the gas temperature on the inner wall of the inner frame 311. Then, the low-temperature gas can be introduced into the insulation box 100 to assist in cooling the operating environment of the electromechanical equipment.
[0021] In some embodiments, optionally, such as Figure 3 , Figure 4 and Figure 5 As shown, the cooling component 310 includes: an inner frame 311, which is fixedly connected to the inner wall of the insulation box 100 and forms a liquid collection chamber 318 with the inner wall of the insulation box 100; a first cold air pipe 312, which is wrapped around the middle of the inner frame 311, with the lower end of the first cold air pipe 312 opening towards the inside of the insulation box 100; and a second cold air pipe 313, one end of which is connected to the first cold air pipe 312, and the other end of which passes through the insulation box 100 and is connected to the cold air end of the vortex tube 200, and the second cold air pipe 313 is wrapped around the surface of the regulating compensation component 320.
[0022] Specifically, the liquid collection chamber 318 formed by the inner frame 311 and the inner wall of the insulation box 100 is used to fill the heat-conducting medium, which significantly increases the heat exchange area; the first cold air pipe 312 is wrapped around the middle of the inner frame 311, and its lower end opening is used to directly release the low-temperature gas flowing through the pipe into the internal space of the insulation box 100, so as to achieve air cooling of the environment of the electromechanical equipment; the second cold air pipe 313 connects the cold air end of the vortex tube 200 and the first cold air pipe 312. Its unique arrangement is that it is pre-wound around the surface of the control and compensation component 320, which allows some of the cold energy to pre-cool the control and compensation component 320 before entering the first cold air pipe 312. In this way, after the cold airflow is generated from the vortex tube 200, it flows sequentially through the second cold air tube 313 and the first cold air tube 312. During this process, on the one hand, the second cold air tube 313 pre-cools the control and compensation component 320, improving the efficiency and potential of subsequent temperature compensation; on the other hand, the first cold air tube 312 releases cold air into the environment for direct convective heat exchange. This achieves a highly efficient path for utilizing cooling capacity in a tiered manner. By optimizing the path and functional allocation of the cold airflow, not only is basic cooling of the environment achieved, but more importantly, a highly efficient low-temperature foundation is provided for the crucial control and compensation function, thereby significantly improving the efficiency and response speed of the entire heat dissipation system.
[0023] In some embodiments, optionally, such as Figure 5 , Figure 6 and Figure 7 As shown, the regulating compensation component 320 includes: a first temperature-conducting pipe 321, fixedly connected to the inner top wall of the liquid collection tank 318, with both ends of the first temperature-conducting pipe 321 penetrating the inner fixed frame 311; a second temperature-conducting pipe 323, disposed at the lower end of the first temperature-conducting pipe 321, with a contact temperature-conducting element 328 for contacting electromechanical equipment fixedly connected to the lower end of the second temperature-conducting pipe 323; a middle temperature-conducting strip 322, slidably disposed in an inner slide rail 324 extending from the upper end of the first temperature-conducting pipe 321 to the lower end of the second temperature-conducting pipe 323; and a driving part 329, connected to the upper end of the middle temperature-conducting strip 322, for driving the middle temperature-conducting strip 322 to slide within the inner slide rail 324 to change the contact area between the middle temperature-conducting strip 322 and the second temperature-conducting pipe 323, thereby adjusting the heat conduction efficiency.
[0024] Specifically, the upper end of the first heat-conducting pipe 321 is closely adjacent to the second cooling pipe 313, and the lower end is connected to the second heat-conducting pipe 323, forming the main heat conduction path from the low-temperature liquid accumulation chamber 318 to the high-temperature electromechanical equipment. The contact heat-conducting element 328 at the lower end of the second heat-conducting pipe 323 maintains close contact with the surface of the electromechanical equipment to ensure efficient heat transfer. The middle heat-conducting strip 322 is slidably connected in the inner slide 324 that runs through the first heat-conducting pipe 321 and the second heat-conducting pipe 323. The drive unit 329 provides precise linear drive. Thus, when the temperature of the electromechanical equipment rises and heat dissipation needs to be enhanced, the drive unit 329 pushes the middle heat-conducting strip 322 downward to slide it deeper into the second heat-conducting pipe 323, thereby increasing the metal contact area between the two. According to Fourier's law of thermal conductivity, increasing the contact area increases the heat flow from the equipment through the second temperature-conducting pipe 323 and the middle temperature-conducting strip 322 to the first temperature-conducting pipe 321 and the liquid collection tank 318, thus improving the thermal conductivity and providing active, compensatory enhanced heat dissipation for the equipment. Conversely, when the heat dissipation demand decreases, the drive unit 329 retracts the middle temperature-conducting strip 322, reducing the contact area and thereby decreasing the thermal conductivity to prevent overcooling. Through the mechanical sliding structure, the continuous and adjustable control of the heat dissipation efficiency of the heat dissipation device is achieved, fundamentally solving the dynamic heat dissipation matching problem of electromechanical equipment under varying operating conditions.
[0025] In some embodiments, optionally, such as Figure 5 , Figure 6 and Figure 7 As shown, the length of the middle temperature-conducting strip 322 is greater than the length of the first temperature-conducting tube 321, so as to ensure that the surface of the middle temperature-conducting strip 322 always remains in contact with the inner wall of the first temperature-conducting tube 321 under the drive of the drive unit 329.
[0026] Specifically, such as Figure 7 As shown, when the middle thermal conductive strip 322 slides up and down under the drive of the drive unit 329, because its total length is greater than that of the first thermal conductive tube 321, regardless of how much its lower end protrudes into the second thermal conductive tube 323, a portion of its upper section is always covered by the inner wall of the first thermal conductive tube 321, thus ensuring a large-area, continuous metal-to-metal contact between the two. This design ensures that the heat flow path from the first thermal conductive tube 321 to the middle thermal conductive strip 322 is uninterrupted at any adjustment position, and the thermal resistance remains stable and minimal. This ensures the integrity and efficiency of the basic heat conduction path of the regulating compensation component 320 during dynamic heat dissipation compensation.
[0027] In some embodiments, optionally, such as Figure 1 , Figure 5 and Figure 6As shown, the drive unit 329 includes: a pen-type electric actuator 327, which is fixedly installed on the inner top wall of the top compartment 110, with the telescopic end of the pen-type electric actuator 327 extending downward; a connector 326, which is fixedly connected between the telescopic end of the pen-type electric actuator 327 and the upper end of the middle temperature-conducting strip 322; and a top conduit 325, which is fixedly connected to the upper end of the first temperature-conducting tube 321, with the connector 326 slidably connected to the inner wall of the top conduit 325 to form a guide.
[0028] Specifically, such as Figure 6 As shown, the pen-type electric actuator 327 serves as the power source, and the connector 326 acts as the connecting component, rigidly connecting the telescopic end of the actuator to the upper end of the central heat-conducting strip 322 to ensure reliable power transmission. The top guide tube 325 is fixed to the upper end of the first heat-conducting tube 321, and its inner wall forms a sliding pair with the connector 326, creating a precise guiding mechanism. Thus, when the heat dissipation power needs adjustment, the pen-type electric actuator 327 is activated, and its telescopic end drives the connector 326 to move linearly under the constraint of the inner wall of the top guide tube 325, thereby pushing the central heat-conducting strip 322 to slide smoothly and vertically within the heat-conducting tube track without deflection or jamming. This ensures that the central heat-conducting strip 322 can precisely control its insertion depth into the second heat-conducting tube 323 according to a preset trajectory, thereby achieving precise and reliable control of the contact area and even the overall heat conduction efficiency.
[0029] In some embodiments, optionally, such as Figure 3 , Figure 4 and Figure 5 As shown, the cooling component 310 also includes: a plurality of inner rotating plates 315, which are spirally fixedly connected to the inner wall of the inner frame 311; and a cold air flow guide plate 314, which is fixedly connected to the inner rotating plates 315 on the side away from the inner frame 311, and its lower end is funnel-shaped, used to guide the cold air flow downward and gather the hot air below.
[0030] Specifically, such as Figure 5As shown, multiple inner spiral plates 315 have a spiral structure and are fixed to the inner wall of the inner frame 311, forming a progressive flow channel. The cold airflow guide plate 314 is connected to the outer edge of the inner spiral plates 315, and its lower flared structure constitutes a key airflow shaping component. In this way, the cold airflow released from the first cold air pipe 312 is guided by the spiral channel formed by the inner spiral plates 315, resulting in an orderly downward spiral flow. This extends the flow path and residence time of the cold air in the insulation box 100, enhancing the efficiency of heat exchange with the environment. On the other hand, the downward spiral airflow is accelerated and diffused at the flared opening of the cold airflow guide plate 314, forming a wider umbrella-shaped airflow curtain, preventing the disorderly diffusion of hot air generated by the electromechanical equipment. At the same time, the converging structure of the flared opening generates a Venturi effect on the rising hot airflow below, helping to gather the dispersed hot air to the central area, creating favorable conditions for the efficient suction of the exhaust component 330.
[0031] In some embodiments, optionally, such as Figure 5 As shown, a skirt plate 316 is also fixedly connected to the lower end of the cold airflow guide plate 314. A moisture-absorbing tube 317 for absorbing moisture in the environment is fixedly connected to the side of the skirt plate 316 away from the cold airflow guide plate 314, and the edge of the skirt plate 316 near the moisture-absorbing tube 317 is wavy.
[0032] Specifically, the skirt-shaped plate 316, as a downward extension of the cold airflow guide plate 314, features a wavy edge design that effectively breaks up and guides condensate droplets flowing down the plate wall, causing them to collect in an orderly manner rather than dripping randomly. The moisture-absorbing pipe 317, fixed to the outside of the skirt-shaped plate 316, is made of a material with a high specific surface area and strong hydrophilicity, enabling it to actively absorb moisture from the environment and the condensate guided there. Thus, in the high-humidity environment of an underground coal mine, when the surface temperature of the low-temperature cold airflow guide plate 314 and the skirt-shaped plate 316 is lower than the air dew point temperature, water vapor in the air will condense on their surfaces. The wavy skirt edge, by changing the direction of the liquid surface tension, disperses, breaks up, and guides large droplets to a predetermined area. Simultaneously, the moisture-absorbing pipe 317 continuously absorbs liquid water and gaseous moisture from the environment in that area, locking the moisture inside the pipe. This significantly reduces the air humidity around the critical equipment inside the insulation box 100, effectively preventing equipment short circuits, metal corrosion, and decreased insulation performance caused by condensate accumulation, thereby improving the reliability and safety of the heat dissipation device under harsh operating conditions.
[0033] In some embodiments, optionally, such as Figure 2 , Figure 8 and Figure 9As shown, the outlet component 330 includes: an outlet duct 331, the lower end of which is connected to the cooling component 310, and the upper end of which is fixedly connected to a cyclone guide seat 332; an exhaust pipe 339, which connects the side of the cyclone guide seat 332 to the hot gas end of the vortex tube 200; and a rotating ring 334, which is rotatably connected to the outlet duct 331 and the cyclone guide seat 332. The airflow introduced into the cyclone guide seat 332 from the hot gas end through the exhaust pipe 339 is configured to drive the rotating ring 334 to rotate, thereby generating a suction force to outlet the hot gas in the insulation box 100 through the outlet duct 331.
[0034] Specifically, the lower end of the exhaust duct 331 is connected to the space above the cold airflow guide plate 314 of the cooling component 310, and the upper end is connected to the cyclone guide seat 332, which serves as a key cavity for airflow conversion and kinetic energy recovery. The exhaust duct 339 guides the hot airflow generated by the vortex tube 200, which is usually discarded, into the cyclone guide seat 332. The rotating ring 334 is driven by the airflow to rotate within the exhaust duct 331 and the cyclone guide seat 332. In this way, the high-pressure hot airflow discharged from the hot air end of the vortex tube 200 enters the cyclone guide seat 332 at a specific angle and high speed through the exhaust duct 339, thereby driving the rotating ring 334 to rotate continuously. The rotational motion of the rotating ring 334, through the rotating shaft 335 connected inside it, synchronously drives the air guide fan blade 337 located in the lower exhaust duct 331 to rotate at high speed. The high-speed rotating air guide fan blades 337 generate a strong negative pressure within the air outlet duct 331, thereby continuously drawing out the hot air accumulated around the equipment and finally discharging it to the outside of the device through the air outlet 336 on the cyclone guide seat 332. By converting the waste hot airflow into a free power source to drive the exhaust component 330, energy recycling of "waste-to-waste" is achieved. This process requires no additional electricity consumption, not only efficiently removing heat from the equipment but also significantly improving the energy efficiency and economy of the entire heat dissipation system.
[0035] In some embodiments, optionally, such as Figure 8 and Figure 9 As shown, a downwardly extending rotating shaft 335 is fixedly connected to the inner wall of the rotating ring 334, and an air guide fan blade 337 located in the air outlet duct 331 is fixedly connected to the lower end of the rotating shaft 335.
[0036] Specifically, the upper end of the rotating shaft 335 is rigidly connected to the inner wall of the rotating ring 334, while the lower end extends into the interior of the outlet duct 331. The guide fan blade 337 is fixedly installed at the lower end of the rotating shaft 335, and its blade structure is optimized to match aerodynamic requirements. Thus, when the rotating ring 334 is driven to rotate by the hot airflow discharged from the vortex tube 200, this rotational motion is transmitted to the guide fan blade 337 located in the downstream outlet duct 331 through the rotating shaft 335. The high-speed rotating guide fan blade 337, as the core suction element, works similarly to an axial flow fan. By doing work on the air through the blades, mechanical energy is converted into the kinetic and pressure energy of the airflow, thereby forming a continuous low-pressure zone on the intake side of the guide fan blade 337, generating a strong suction force; while on its outlet side, a high-pressure zone is formed, pushing the airflow upwards for discharge.
[0037] In some embodiments, optionally, such as Figure 8 and Figure 9 As shown, an arc-shaped plate 338 is fixedly connected to the surface of the rotating ring 334. The other end of the arc-shaped plate 338 extends into the interior of the cyclone guide seat 332 and is rotatably connected to the inner wall of the cyclone guide seat 332. The concave surface of the arc-shaped plate 338 is configured as a windward surface to be driven by the airflow.
[0038] Specifically, one end of the arc-shaped plate 338 is fixed to the surface of the rotating ring 334, and the other end extends into the interior of the cyclone guide seat 332 via a rotatable connection, forming a cantilevered force-bearing structure. Thus, when the hot airflow entering the cyclone guide seat 332 from the exhaust pipe 339 impacts the concave surface of the arc-shaped plate 338, the curved surface structure can more effectively capture and accommodate the airflow. According to fluid mechanics principles, the airflow velocity changes at the concave surface, generating a pressure difference, thereby applying a more concentrated and powerful tangential force to the plate surface. This tangential force generates a continuous rotational torque around the axis of the rotating ring 334, efficiently driving the rotating ring 334 to rotate. The rotatable connection between the arc-shaped plate 338 and the inner wall of the cyclone guide seat 332 ensures structural stability and smooth movement when transmitting huge torques.
[0039] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9As shown, the outlet assembly 330 includes an outlet duct 331 fixedly connected to the upper end of the inner frame 311. The lower end of the outlet duct 331 is connected to the upper end of the cold air flow guide plate 314. A cyclone guide seat 332 is fixedly connected to the upper end of the outlet duct 331. An exhaust pipe 333 is fixedly connected to the upper end of the cyclone guide seat 332. A rotating ring 334 is rotatably connected to the inner wall of the outlet duct 331. An exhaust pipe 339 connected to the cyclone guide seat 332 is fixedly connected to the side of the cyclone guide seat 332. The other end of the exhaust pipe 339 is connected to the hot air end of the vortex tube 200. Air outlets 336 are provided on both the upper and lower end faces of the cyclone guide seat 332. A rotating shaft 335 is fixedly connected to the inner wall of the rotating ring 334. An air guide fan blade 337 is fixedly connected to the lower end of the rotating shaft 335. An arc-shaped plate 338 is fixedly connected to the surface of the rotating ring 334. The other end of the arc-shaped plate 338 passes through the interior of the cyclone guide seat 332 and is rotatably connected to the inner wall of the cyclone guide seat 332.
[0040] In use, the airflow from the hot gas end is directed outward through the outlet duct 331. The airflow from the outlet duct 331 is guided into the cyclone guide seat 332. Due to the guiding effect of the gas blowing out from inside the cyclone guide seat 332 and the edge of the cyclone guide seat 332, the hot airflow enters the cyclone guide seat 332 and blows the arc-shaped plate 338. The arc-shaped plate 338 is designed with its concave surface facing the wind. When the outlet duct 331 discharges air, it blows the arc-shaped plate 338, causing the rotating ring 334 to rotate. The airflow passes through the arc-shaped plate 338 and is discharged outward through the diffuser 336 on the surface of the cyclone guide seat 332. When the rotating ring 334 rotates, it causes the rotating shaft 335, which is fixedly connected to its inner wall, to rotate as well. The rotating shaft 335 then drives the guide fan blades 337 on the inner wall of the outlet duct 331 to rotate, thus allowing the hot air discharged from the vortex tube 200 to guide and discharge the hot air generated by the electromechanical equipment.
[0041] In practical applications, the technical principle of the heat dissipation device 10 with temperature compensation function for coal mine electromechanical equipment is as follows: When the device is in use, the electromechanical equipment used in the coal mine is placed inside the moisture absorption pipe 317, with the equipment located inside the moisture absorption pipe 317. The air inlet pipe injects high-pressure gas into the vortex pipe 200, and the low-temperature gas is introduced into the second cold air pipe 313 through the vortex pipe 200. The low-temperature gas is then introduced into the insulation box 100 through the first cold air pipe 312. The second cold air pipe 313 is wrapped around the surface of the first temperature-conducting pipe 321, and the first temperature-conducting pipe 321 slides with the internal central temperature-conducting strip 3. 22. Heat exchange: The upper part of the middle heat-conducting strip 322 contacts the inner wall of the first heat-conducting tube 321, and the lower part of the middle heat-conducting strip 322 contacts the inner wall of the second heat-conducting tube 323. The extension end of the pen-type electric push rod 327 moves down through the connector 326, causing the upper end of the middle heat-conducting strip 322 to move down as well. As the connector 326 moves down, the lower surface of the middle heat-conducting strip 322 increases the contact area with the inner wall of the second heat-conducting tube 323, thereby enhancing the heat exchange effect between the second heat-conducting tube 323 and the electromechanical equipment through the contact heat-conducting component 328, and achieving a heat dissipation and cooling compensation effect for the electromechanical equipment. The airflow at the hot end of the device is guided into the cyclone guide seat 332 through the outlet duct 331. The gas inside the cyclone guide seat 332 blows the arc plate 338, causing the rotating ring 334 to rotate. The airflow flows through the arc plate 338 and is discharged to the outside through the air outlet 336 opened on the surface of the cyclone guide seat 332. When the rotating ring 334 rotates, it drives the rotating shaft 335 fixedly connected to its inner wall to rotate as well. At this time, the rotating shaft 335 drives the air guide fan blade 337 on the inner wall of the outlet duct 331 to rotate. Thus, the hot air discharged from the vortex tube 200 drives the exhaust component 330 to guide the hot air generated by the electromechanical equipment to be discharged, thereby enhancing the heat dissipation effect.
