[0002] The magnetic suspension fan is a ventilation equipment in which a rotor is suspended by a magnetic bearing, has the characteristics of extreme energy saving and low operation and maintenance, and is suitable for long-time work, and is therefore widely applied to high spaces such as stations, stadiums and airports. The airflow sucked by the magnetic suspension fan generally needs to be heat-exchanged by an efficient energy-saving heat exchange device and then pass through a duct to reach an air outlet. A remote secondary regulation system controlled by a central control is arranged at the air outlet to perform operations such as pressurizing the blown airflow or adjusting the airflow direction.

Meanwhile, the stator in the middle of the magnetic suspension fan occupies a large space, the heat dissipation airflow flowing through has low heat dissipation efficiency and is easily heated, which affects the heat dissipation effect of the airflow after flowing through.

DETAILED DESCRIPTION

[0028] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings, but the scope of protection of the present application is not limited by the specific embodiments.

[0029] Unless otherwise clearly indicated, throughout the specification, the term "comprising" or variations such as "comprise" or "comprises" will be understood to encompass the elements or components stated, but not to exclude other elements or components.

[0030] Reference Figures 1-9 The present embodiment provides a technical solution as shown in the drawings: A high-space, long-range, secondary-regulation, cooling and heating fan based on a high-efficiency, energy-saving heat exchange device, comprising a cabinet 100, a fan 200 installed within the cabinet 100, and a heat exchanger 500. The fan 200 is a magnetically levitated fan, internally equipped with a drive motor that rotates a rotor to drive an impeller and draw in air. Two sets of radial magnetic bearings control the radial position of the rotor, and one set of axial magnetic bearings controls the axial position of the rotor, thus maintaining the rotor stably levitated within the fan 200. The magnetically levitated fan and heat exchanger 500 are existing technologies; their specific principles will not be elaborated here. Although the magnetic... The levitation fan is suspended in space by magnetic force. The low friction significantly reduces heat generated by mechanical friction. However, during high-speed operation, the current-controlled electromagnetic coils, electronic components, and the rotor's friction with the air all generate heat. Prolonged, high-intensity use will still cause the internal temperature of the fan 200 to rise, affecting the magnetic force within the levitation fan and leading to rotor instability and damage to the entire machine. The cabinet 100 contains a heat dissipation assembly 300 for cooling the fan 200. The heat dissipation assembly 300 includes an exhaust duct 301, an exhaust fan 302 installed within the exhaust duct 301, and a mechanism to drive the exhaust fan. A rotating drive fan 303 is connected to the left end of a blower 200 via an exhaust pipe 301. The blower 200 has a volute 203 for air outlet, and the drive fan 303 is installed inside the volute 203. Several air inlets 205 are located on the right side wall of the blower 200. The drive fan 303 and the exhaust fan 302 are connected by a transmission mechanism. When the blower 200 is running, the airflow drawn in passes through the drive fan 303, causing it to rotate. This rotation is then transmitted through the first transmission structure 310, which in turn drives the exhaust fan 302 to rotate and draw air out of the exhaust pipe 301. During the exhaust process... Airflow enters the fan 200 through the air inlet 205 to cool the internal components. The exhaust fan 302 rotates along with the drive fan 303. The speed of the drive fan 303 is related to the airflow velocity drawn into the fan 200. Therefore, as the working intensity of the fan 200 increases, the airflow velocity increases, which will drive the speed of the exhaust fan 302 to increase, thereby accelerating heat dissipation. This makes the heat dissipation intensity of the exhaust fan 302 match the working intensity of the fan 200, avoiding excessive heat dissipation and waste. At the same time, there is no need to manually control the heat dissipation intensity to match the working intensity of the fan 200, which is convenient and practical. The peristaltic pump 304 is driven by the second transmission structure 320 below the first transmission structure 310, the ring cavity 206 is arranged in the middle of the outer wall of the fan 200, two groups of heat dissipation fins 2061 are fixed in the ring cavity 206, the water cooling pipe 305 is arranged on the outer wall of the ring cavity 206, the water tank 306 is fixed below the fan 200 in the cabinet 100, one end of the water cooling pipe 305 penetrates the peristaltic pump 304 and extends into the front end of the water tank 306, and the other end extends into the rear end of the water tank 306, wherein the peristaltic pump 304 is a device for pumping water by rotating the rotor to drive the roller to extrude the soft pipe, which is a prior art and will not be described here. During the heat dissipation process of the exhaust fan 302, the first transmission structure 310 drives the second transmission structure 320 to rotate and drives the rotor of the peristaltic pump 304 to rotate, so that the cold water in the water tank 306 is pumped into the water cooling pipe 305. When the water flows through the ring cavity 206, the heat dissipation fins 2061 cool the stator 204 and the airflow flowing through the stator 204. After the heat dissipation airflow enters the fan 200 through the air inlet hole 205, the small middle space of the fan 200 operates at high strength and relies only on air cooling, which is difficult to achieve the heat dissipation effect. Moreover, the heat generated by the fan 200 increases the temperature of the airflow after flowing through, which reduces the heat dissipation effect of the airflow on the left segment of the fan 200. By arranging the water cooling pipe 305, the middle part of the fan 200 can be water-cooled and cooled, and the airflow flowing through can also be cooled, so as to avoid affecting the heat dissipation effect of the left segment of the fan 200.

[0031] Please refer to Figures 1-2 As shown in the figure, the cabinet 100 is provided with air windows 101 on the left and right sides and the rear side. It should be noted that the right air window 101 has a small air hole to prevent dust and debris from entering the cabinet 100. The support plate 103 is welded and fixed in the middle of the cabinet 100. The fan 200 is fixed on the support plate 103 by bolts. The water tank 306 is fixed below the support plate 103. The sealing door 102 is hinged to the front wall of the cabinet 100.

[0032] Further, the fan 200 is provided with an air inlet 202 at the right end, and the air inlet 202 is fixed with a wind guide frame 201. The wind guide frame 201 is in the shape of a horn with a smaller left end and a larger right end, and the opening area of the right end is larger than the distribution area of the right air window 101, so that the wind guide frame 201 can completely cover the right air window 101 and ensure the air inlet area. The heat exchanger 500 is fixed in the cabinet 100 by bolts near the left end. The volute 203 and the heat exchanger 500 are communicated through the air guide pipe 400. The top end of the air outlet pipe 600 communicates with the heat exchanger 500. The top end of the air outlet pipe 600 penetrates out of the cabinet 100. After the fan 200 is started, the impeller rotates to suck air flow from the air inlet 202. Then the air flow enters the air guide pipe 400 through the volute 203, flows along the air guide pipe 400, enters the heat exchanger 500 for heat exchange, and then flows to the air outlet through the pipeline. A secondary adjusting device is arranged at the air outlet to increase the air pressure or adjust the air direction.

[0033] Please refer to Figures 3-5 As shown in the figure, the first transmission structure 310 includes a horizontally arranged first transmission rod 311, and a first gear set 312 and a second gear set 313 arranged at the left and right ends of the first transmission rod 311. The exhaust fan 302 and the transmission fan 303 are both mounted in the exhaust pipe 301 and the volute 203 through the mounting bracket 307, respectively. During the operation of the fan 200, when the air flow is drawn through the transmission fan 303, it drives the transmission fan 303 to rotate and drives the first transmission rod 311 to rotate through the first gear set 312, and then drives the exhaust fan 302 to rotate through the second gear set 313 to exhaust air outside the exhaust pipe 301. During the exhaust process, the air flow enters the fan 200 through the air inlet hole 205 to cool the internal elements, and it should be noted that the first gear set 312 and the second gear set 313 are both composed of two intermeshing bevel gears, wherein the horizontal bevel gear is coaxially fixed with the central shaft of the corresponding mounting bracket 307, the central shaft of the mounting bracket 307 is rotationally connected with the base of the mounting bracket 307, and the central shaft of the mounting bracket 307 is coaxially fixedly connected with the corresponding exhaust fan 302 and transmission fan 303.

[0034] Specifically, the first gear set 312 is located above the transmission fan 303, and the second gear set 313 is located below the exhaust fan 302, so as to avoid the first gear set 312 blocking the exhaust fan 302 and the second gear set 313 blocking the air flow driving the transmission fan 303. The diameter of the transmission fan 303 is smaller than the diameter of the air outlet of the volute 203, so as to avoid the transmission fan 303 being too large to block the volute 203 and affect the normal operation of the fan 200.

[0035] Please refer to Figure 6 As shown in the figure, the second transmission structure 320 includes a second transmission rod 321 arranged vertically to the first transmission rod 311, a first worm gear 322 coaxially fixed at the top end of the second transmission rod 321, and a second worm gear 323 coaxially fixed at the bottom end of the second transmission rod 321. The first transmission rod 311 has a first worm gear 314 coaxially fixed at the left end, and the first worm gear 314 is engaged with the first worm gear 322. During the rotation of the first transmission rod 311, the first worm gear 314 synchronously drives the first worm gear 322 to rotate and drives the second transmission rod 321 to rotate, and then drives the second worm gear 323 to rotate.

[0036] Further, the second worm gear 324 is coaxially fixed on the front side of the middle rotor of the peristaltic pump 304, the second worm gear 324 is engaged with the second worm 323, the peristaltic pump 304 is bolted on the left side of the supporting plate 103, the L-shaped bracket 104 is welded and fixed on the front side of the left end of the supporting plate 103, the front end of the second worm 323 is embedded in the rear side wall of the vertical section of the bracket 104 and is rotationally connected with the bracket 104, the bottom end of the second transmission rod 321 penetrates through the horizontal section of the bracket 104 and is rotationally connected with the top surface of the supporting plate 103, when the second worm 323 rotates, the rotor of the peristaltic pump 304 is driven to rotate by the second worm gear 324 to pump water, so that the cold water in the water tank 306 is pumped into the water cooling pipe 305, and the water flow passes through the annular cavity 206 and is cooled by the heat dissipation fins 2061 for the stator 204 and the airflow passing through the stator 204.

10. A method for secondary regulation of large spaces using magnetic levitation based on a high-efficiency energy-saving heat exchange device, employing the remote cooling and heating fan for large spaces using magnetic levitation based on a high-efficiency energy-saving heat exchange device as described in claim 9, characterized in that... Includes the following steps: S1. When the power is turned on, the fan drives the impeller to rotate and draw in air. The airflow passes through the air guide frame, air inlet and volute and then enters the heat exchanger through the air guide pipe for heat exchange. After that, it enters the subsequent secondary adjustment device through the air outlet pipe to pressurize and adjust the airflow direction. S2. During the operation of the fan, when the airflow passes through the transmission fan, it drives the transmission fan to rotate and drives the first transmission rod to rotate through the first gear set. Then, through the second gear set, it drives the exhaust fan to rotate and exhaust air to the outside of the exhaust pipe. During the exhaust process, the airflow enters the fan through the air inlet to cool the internal components. S3. During the rotation of the first transmission rod, the first worm synchronously drives the first worm wheel to rotate, which in turn drives the second transmission rod to rotate. This, in turn, drives the peristaltic pump rotor to rotate through the second worm and the second worm wheel, causing the cold water in the water tank to be pumped into the water cooling pipe. When the water flows through the annular cavity, it cools the stator and the airflow flowing through the stator through the heat dissipation fins.
