Description

Technical Field

[0001] This invention relates to the field of electromechanical equipment cooling technology, specifically to an active electromechanical equipment cooling device and method. Background Technology

[0002] Electromechanical equipment generally refers to machinery, electrical appliances, and electrical automation equipment. With continuous technological improvements, traditional mechanical equipment has entered a new stage of mechanical and electrical integration, and its application scope is constantly expanding. From transportation vehicles to various household appliances, computers, printers, etc., it has become an indispensable electromechanical product in people's lives. Advanced electromechanical equipment can greatly improve labor productivity, reduce labor intensity, improve the production environment, and accomplish tasks that cannot be done by human hands, thus greatly improving people's lifestyles.

[0003] Currently, most cooling devices for electromechanical equipment, in practical use, cool the entire cavity containing the equipment. For example, the patent publication "CN114051367B" describes an intelligent cooling protection device for electromechanical equipment. A temperature sensor monitors the temperature inside the cooling cavity. When the sensor detects excessively high temperatures, it sends a signal to the control box, which immediately opens a second solenoid valve. Because the negative pressure tank is under negative pressure, opening it quickly extracts heat from the cooling cavity, rapidly reducing its temperature and significantly improving the cooling protection effect on the equipment. However, this cooling method requires a relatively large cooling space, and the cooling process is not precise or concentrated enough, resulting in energy waste and poor energy efficiency.

[0004] Therefore, it is necessary to invent an active cooling device and method for electromechanical equipment to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an active cooling device and method for electromechanical equipment. An adjustable temperature monitoring mechanism monitors the temperature of the main body of the electromechanical equipment and identifies locations with excessively high temperatures. A controller then activates a fan and solenoid valve behind these locations. This allows for precise cooling of the overheated areas of the equipment, with a smaller cooling space, effectively reducing the energy required for cooling and thus improving the energy efficiency of the cooling device. This addresses the aforementioned shortcomings in the technology.

One end of the liquid inlet pipe passes through the rear end of the cooling protection box and extends into the cooling cavity. A liquid pump is installed inside the cooling cavity. One end of the liquid inlet pipe is connected to the liquid outlet of the liquid pump. The other end of each of the three disc-shaped heat-conducting pipes is fixedly provided with a liquid outlet pipe that communicates with its interior. One end of the liquid outlet pipe passes through the rear end of the cooling protection box and communicates with the interior of the cooling cavity. A cooler is installed at the bottom of the interior of the cooling cavity.

[0010] Preferably, the position adjustment mechanism includes two fixed plates fixedly disposed at the top and bottom of the outer side of the L-shaped heat-conducting plate, and a fixed guide rod fixedly disposed between the two fixed plates. The fixed guide rod passes through multiple heat dissipation fins, and multiple first springs are provided at the outer end of the fixed guide rod.

[0011] Preferably, each of the four outer corners of the L-shaped heat-conducting plate is fixedly provided with a telescopic rod, and the heat dissipation fins are arranged between the four telescopic rods. One end of the telescopic rod is fixedly connected to the inner side wall of the mounting cavity, and the outer end of the telescopic rod is provided with a second spring. The two ends of the second spring are fixedly connected to the outer side of the L-shaped heat-conducting plate and the inner side wall of the mounting cavity, respectively, so as to facilitate the L-shaped heat-conducting plate to be tightly attached to the outer side of the main body of the electromechanical equipment.

[0012] Preferably, the cooling protection box has a hinged door at the front end, which facilitates the protection of the main electromechanical equipment inside the cooling protection box.

[0014] Preferably, the cooling protection box has air vents on both sides, the air vents are connected to the interior of the mounting cavity, and a second filter plate is fixed on the inner wall of the air vent to facilitate the discharge of hot air from inside the cooling protection box.

[0015] It also includes the method of using the device, the steps of which are as follows:

[0016] S1: Install the main body of the electromechanical equipment on the top of the partition plate, so that the two L-shaped heat conduction plates are attached to both sides of the main body of the electromechanical equipment. Start the motor. The output shaft of the motor drives the threaded rod to rotate. The movable support plate moves up and down with the rotation of the threaded rod. The movable support plate drives the temperature sensor to move up and down. The temperature sensor will monitor the temperature on the main body of the electromechanical equipment and transmit the monitoring data to the controller. When the temperature sensor detects that the temperature on the main body of the electromechanical equipment is too high, the distance sensor will transmit the location of the excessively high temperature on the main body of the electromechanical equipment to the controller.

[0017] S2: The controller determines the location of the excessively high temperature detected by the temperature sensor, and controls the fan behind that location to start. The solenoid valves at both ends of the disc-shaped heat pipe behind that location will open, starting the liquid pump. The cooling medium inside the cooling chamber will enter the disc-shaped heat pipe with the solenoid valves opened through the inlet pipe, and then return to the cooling chamber through the outlet pipe for cooling. The cooling medium flowing through the disc-shaped heat pipe will exchange heat with the air blown by the fan, and the air temperature will be reduced. The cooled air will be blown to the high-temperature location on the main body of the electromechanical equipment, thus achieving precise cooling of the main body of the electromechanical equipment.

[0018] S3: After determining the location of the excessively high temperature on the main body of the electromechanical equipment, the controller controls the electro-hydraulic rod to open. The electro-hydraulic rod will compress multiple heat dissipation fins to the outside of the high-temperature area. In this way, the heat on the main body of the electromechanical equipment will be accelerated to be discharged through the L-shaped heat conduction plate and multiple heat dissipation fins, which can improve the cooling efficiency.

[0019] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0020] 1. The adjustable temperature monitoring mechanism monitors the temperature of the main body of the electromechanical equipment and identifies the location of excessive temperature. The controller then controls the opening of the fan and solenoid valve behind the location of excessive temperature. This allows for precise cooling of the location of excessive temperature on the main body of the electromechanical equipment. The cooling space is small, which effectively reduces the energy used for cooling and thus makes the cooling device more energy-efficient.

[0021] 2. By using a position adjustment mechanism to evenly concentrate multiple heat dissipation fins on the outer side of the area with excessively high temperature, the heat dissipation speed at that location can be accelerated, the heat dissipation efficiency at that location can be improved, and the cooling and heat dissipation efficiency can be further improved, making it highly practical.

The threaded rod 10 is threadedly connected to the movable support plate 8. A motor 11 is fixedly provided on the top of the cooling protection box 1. The top of the threaded rod 10 is fixedly connected to the output shaft of the motor 11. A motor box 12 is fixedly provided on the top of the cooling protection box 1. The motor 11 is located inside the motor box 12.

[0036] A connecting frame 14 is fixedly provided at the rear end of the cooling protection box 1. Three fans 15 are fixedly provided on the rear wall inside the connecting frame 14. The fans 15 are connected to the output end of the controller 13. Multiple ventilation holes 16 are provided at the rear end of the cooling protection box 1. The interior of the connecting frame 14 and the interior of the mounting cavity 3 are connected through the ventilation holes 16.

[0037] The cooling mechanism includes three disc-shaped heat conduction pipes 17 fixedly installed on the rear wall inside the mounting cavity 3. The disc-shaped heat conduction pipes 17 are located behind the adjustable temperature monitoring mechanism. Both ends of the disc-shaped heat conduction pipes 17 pass through the rear end of the cooling protection box 1 and extend into the connecting frame 14. Both ends of the disc-shaped heat conduction pipes 17 are fixedly equipped with electromagnetic valves 18, which are connected to the output end of the controller 13. One end of each of the three disc-shaped heat conduction pipes 17 is fixedly equipped with an inlet pipe 19 that communicates with its interior. One end of the inlet pipe 19 passes through the rear end of the cooling protection box 1 and extends into the cooling cavity 4. The cooling cavity 4 is equipped with a liquid pump 20. One end of the inlet pipe 19 is connected to the liquid outlet of the liquid pump 20. The other end of each of the three disc-shaped heat conduction pipes 17 is fixedly equipped with an outlet pipe 21 that communicates with its interior. One end of the outlet pipe 21 passes through the rear end of the cooling protection box 1 and communicates with the interior of the cooling cavity 4. The bottom of the cooling cavity 4 is equipped with a cooler 22, and the heat dissipation surface of the cooler 22 is connected to the outside of the cooling protection box 1.

[0038] Telescopic rods 27 are fixedly installed at the four corners of the outer side of the L-shaped heat-conducting plate 6. Heat dissipation fins 7 are located between the four telescopic rods 27. One end of the telescopic rod 27 is fixedly connected to the inner side wall of the mounting cavity 3. A second spring 28 is provided at the outer end of the telescopic rod 27. The two ends of the second spring 28 are fixedly connected to the outer side of the L-shaped heat-conducting plate 6 and the inner side wall of the mounting cavity 3, respectively.

[0039] The rear end of the connecting frame 14 has three air inlets 30, which are located at the air inlet end of the fan 15.

[0040] The main body 5 of the electromechanical equipment is installed on the top of the partition plate 2, so that the two L-shaped heat-conducting plates 6 are attached to both sides of the main body 5 of the electromechanical equipment. The motor 11 is started, and the output shaft of the motor 11 drives the threaded rod 10 to rotate. Since the threaded rod 10 is threadedly connected to the movable support plate 8 and the two L-shaped heat-conducting plates 6 limit the two sides of the movable support plate 8, the movable support plate 8 moves up and down with the rotation of the threaded rod 10. The movable support plate 8 drives the temperature sensor 9 to move up and down. The temperature sensor 9 will monitor the temperature on the main body 5 of the electromechanical equipment and transmit the monitoring data to the controller 13. When the temperature sensor 9 detects that the temperature on the main body 5 of the electromechanical equipment is too high, the distance sensor will transmit the location of the excessively high temperature on the main body 5 of the electromechanical equipment to the controller 13.

[0041] The controller 13 determines the location of the excessively high temperature detected by the temperature sensor 9 on the main body of the electromechanical equipment 5. The controller 13 then controls the fan 15 behind that location to turn on, and the solenoid valves 18 at both ends of the disc-shaped heat pipe 17 behind that location to open, starting the liquid pump 20. The cooling medium inside the cooling chamber 4 enters the disc-shaped heat pipe 17 with the solenoid valves 18 open through the liquid inlet pipe 19, and then returns to the cooling chamber 4 through the liquid outlet pipe 21 for cooling. The cooling medium flowing through the disc-shaped heat pipe 17 exchanges heat with the air blown by the fan 15, lowering the air temperature. The cooled air is then blown to the high-temperature location on the main body of the electromechanical equipment 5, thus achieving precise cooling of the main body of the electromechanical equipment 5.

[0042] This invention uses an adjustable temperature monitoring mechanism to monitor the temperature of the main body 5 of the electromechanical equipment and determine the location of excessively high temperatures. Then, the controller 13 controls the opening of the fan 15 and the solenoid valve 18 behind the location of the excessively high temperature. This allows for precise cooling and heat dissipation of the excessively high temperature location on the main body 5 of the electromechanical equipment. The cooling space is small, effectively reducing the energy used for cooling, thus resulting in a better energy-saving effect of the cooling device. This embodiment specifically solves the problem that in the actual use of existing electromechanical equipment cooling devices, most of which cool the entire cavity where the electromechanical equipment is located. This cooling method requires a large cooling space, and the cooling process is not accurate and concentrated enough, which wastes energy and results in poor energy-saving effect of the cooling device.

[0043] This invention provides, for example Figure 3 and 4 The active electromechanical equipment cooling device and method shown includes a position adjustment mechanism comprising two fixed plates 23 fixedly disposed at the top and bottom of the outer side of an L-shaped heat-conducting plate 6. A fixed guide rod 24 is fixedly disposed between the two fixed plates 23. The fixed guide rod 24 passes through multiple heat dissipation fins 7. Multiple first springs 25 are provided at the outer end of the fixed guide rod 24. The two ends of the multiple first springs 25 are respectively fixedly connected to the top and bottom of the multiple heat dissipation fins 7. An electric hydraulic rod 26 is fixedly disposed on the inner side of the fixed plate 23. One end of the two electric hydraulic rods 26 is respectively fixedly connected to the outer side of the top and bottom heat dissipation fins 7. The electric hydraulic rods 26 are connected to the output end of the controller 13.

[0044] After determining the location of excessively high temperature on the main body 5 of the electromechanical equipment, the controller 13 controls the electric hydraulic rod 26 to open. The electric hydraulic rod 26 compresses multiple heat dissipation fins 7 to the outside of the high-temperature area. In this way, the heat on the main body 5 of the electromechanical equipment is accelerated to be discharged through the L-shaped heat conduction plate 6 and multiple heat dissipation fins 7, which can improve the cooling efficiency. This invention uses a position adjustment mechanism to evenly concentrate multiple heat dissipation fins 7 on the outside of the excessively high temperature location, which can accelerate the heat dissipation speed at that location, improve the heat dissipation efficiency at that location, and further improve the cooling efficiency, making it highly practical.

[0045] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
