Description

Technical Field

[0001] The present invention relates to the technical field of air cooling for new energy products, and specifically to a combined air-cooled housing. Background Art

[0002] With the rapid development of fields such as 5G communication, data centers, industrial control, and new energy equipment, the power density and integration degree of power electronic devices (such as inverters, frequency converters, servers, power modules, etc.) have been continuously increasing, and the heat generation per unit volume has increased significantly. For example, in the high-frequency switching power supplies of communication base stations and the high-density server clusters in data centers, a large amount of heat is generated when the core components such as internal chips and circuit boards are operating. If the heat cannot be dissipated in time, it will cause the temperature of the equipment to be too high. Air cooling (forced air convection) is one of the most important heat dissipation methods for medium and small power electronic / electrical equipment (such as communication equipment, servers, frequency converters, inverters, power modules, industrial computers, charging piles, LED lighting, etc.) due to its relatively low cost, simple implementation, mature technology, and easy maintenance.

[0003] The heat generation areas of the air-cooled housing are different, which will also make the heat absorption areas of the heat dissipation fins different. Due to the fixed installation of the fans on the housing surface, the output direction of the air flow will be fixed. At this time, the air flow generated in the gaps between multiple groups of fans is small, which is not convenient for cooling the heat dissipation fins. Moreover, the air flow generated during fan cooling may bring external dust into the housing, causing the dust to gradually accumulate on the surface of the heat dissipation fins, forming a heat insulation layer, hindering the effective transfer of heat, thereby reducing the heat dissipation efficiency of the fans and causing the temperature inside the housing to rise.

[0004] In view of the above problems, there is an urgent need for innovative design on the original basis. Summary of the Invention

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Please refer to Figures 1-11, the present invention provides a technical solution: a combined air-cooled housing, including a box body 1, a top plate 2 is installed on the top end of the box body 1 through bolts, heat dissipation fins 3 are installed at the bottom of the box body 1, a first cover 4 is installed at the bottom of the box body 1, a second cover 5 is installed at the bottom of the first cover 4, a first adjustment platform 6 is installed at the bottom of the first cover 4 on the side away from the second cover 5, a fan 7 is slidably limited inside the first cover 4, an adjustment plate 9 is slidably limited at the bottom end inside the first cover 4, a first electric push rod 8 is installed on the front surface of the first cover 4, and the extending end of the first electric push rod 8 is connected to the adjustment plate 9. A temperature reduction and cleaning component is arranged inside the first cover 4 and the second cover 5, and a dust removal and cleaning mechanism is arranged on the left side of the first cover 4; The temperature reduction and cleaning component includes a rotating plate 101 rotatably connected inside the first cover 4, and also includes a switching plate 103 rotatably connected inside the notch at the bottom end of the first cover 4. A first gear 104 and a second gear 105 are rotatably connected to the rear end of the first cover 4. A second electric push rod 106 is installed on the rear surface of the first cover 4, and a rack 107 is installed at the extending end of the second electric push rod 106. The rack 107 meshes with the first gear 104 and the second gear 105. A second adjustment platform 108 is installed inside the second cover 5, and a baffle 109 is slidably limited at the top end inside the second cover 5. The inside of the baffle 109 is threadedly connected to the lead screw inside the second adjustment platform 108. The temperature reduction and cleaning component can locally cool the heat dissipation fins 3 while cleaning the dust on the surface of the heat dissipation fins 3, and perform centralized heat dissipation on the high-temperature areas of the heat dissipation fins 3, avoiding energy waste that may be caused by overall heat dissipation.

[0021] As an implementation manner of the present invention, the heat dissipation fins 3 are located inside the first cover 4, a cover plate 11 is installed on the left side of the first cover 4, and air vent grooves are opened on the surface of the cover plate 11. The opening of the air vent grooves on the surface of the cover plate 11 forms an air inlet for the fan 7, which can initially block external dust; As an implementation manner of the present invention, the number of fans 7 is three groups, and the three groups of fans 7 are evenly distributed inside the first cover 4. The convex blocks at the bottom ends of the fans 7 are threadedly connected to the lead screws inside the first adjustment platform 6, and temperature sensors are installed on the output end surfaces of the fans 7. The three groups of fans 7 can evenly cool the inside of the first cover 4, thereby improving the temperature reduction effect on the heat dissipation fins 3; As an implementation manner of the present invention, air vent holes are opened at the bottom end inside the first cover 4, and air vent holes with the same specifications as the inside of the first cover 4 are opened inside the adjustment plate 9. The air vent holes at the bottom end inside the first cover 4 and the air vent holes inside the adjustment plate 9 are staggered. The opening of the air vent holes inside the first cover 4 and the adjustment plate 9 can flexibly adjust the diameter of the output air flow; As an implementation manner of the present invention, the internal rotating shaft of the rotating plate 101 penetrates through the side end of the first housing 4 and is connected to the first gear 104, and the internal rotating shaft of the opening and closing plate 103 penetrates through the side end of the first housing 4 and is connected to the second gear 105. When the rack 107 drives the first gear 104 and the second gear 105 to rotate synchronously, the rotating plate 101 and the opening and closing plate 103 can be driven to rotate synchronously; As an implementation manner of the present invention, an extension plate 102 is limitedly slid in the internal chute of the rotating plate 101. A spring is installed on the inner wall of the chute of the extension plate 102, and the other end of the spring is connected to the extension plate 102. An arc-shaped groove is opened on the inner side wall of the first housing 4. A convex block is installed at the side end of the extension plate 102, and the convex block is limitedly slid in the arc-shaped groove inside the first housing 4. When the rotating plate 101 rotates, the extension plate 102 can be extended to allow air flow to enter the second housing 5; As an implementation manner of the present invention, the dust removal and cleaning mechanism includes a scraper 122 that is limitedly slid on the surface of the cover plate 11, and also includes a cleaning table 123 installed in the bottom groove of the box body 1. A first oil cavity 124 is opened inside the bottom end of the cleaning table 123. A first piston rod 125 is limitedly slid inside the first oil cavity 124. A scraping table 126 is installed at the bottom end of the first piston rod 125. A second oil cavity 127 is opened inside the top end of the cleaning table 123. A second piston rod 128 is limitedly slid inside the second oil cavity 127. The dust removal and cleaning mechanism can clean the air inlet of the fan 7 to avoid dust accumulation at the air inlet and reduce the problem of dust adhering to the surface of the heat dissipation fins 3; As an implementation manner of the present invention, a moving table 121 is installed at the side end of the first housing 4. The scraper 122 is threadedly connected to the internal lead screw of the moving table 121. The scraper 122 is closely attached to the surface of the cover plate 11. The cleaning table 123 is limitedly slid in the bottom groove of the box body 1. The end of the second piston rod 128 is connected to the side wall of the bottom groove of the box body 1. The first oil cavity 124 is communicated with the second oil cavity 127. When the cleaning table 123 moves, it can clean the scraper 122; The airflow generated in the gaps between multiple groups of fans 7 is small, which is not convenient for cooling the heat dissipation fins 3. The airflow generated during the cooling of the fans 7 may bring external dust into the housing, causing the dust to gradually accumulate on the surface of the heat dissipation fins 3. The specific implementation method is as follows. When the heat dissipation fins 3 absorb the heat generated inside the box body 1, the controller drives the fans 7 to work, and drives the screw rod inside the first adjustment table 6 to rotate through the motor. The screw rod drives the fans 7 to reciprocate inside the first housing 4 to evenly cool the heat dissipation fins 3. While the motor drives the screw rod inside the first adjustment table 6 to rotate, the controller will drive the screw rod inside the moving platform 121 to rotate reciprocally through the motor, driving the screw rod inside the moving platform 121 to rotate reciprocally, and driving the scraper 122 to move on the surface of the cover plate 11. When the scraper 122 touches the scraping platform 126, at this time, the scraping platform 126 squeezes the first piston rod 125 to inject the oil liquid inside the first oil chamber 124 into the second oil chamber 127. The increase in the oil liquid inside the second oil chamber 127 squeezes the second piston rod 128, causing the second piston rod 128 to extend from the inside of the second oil chamber 127. The extension of the second piston rod 128 drives the cleaning platform 123 to slide in a limited manner in the bottom groove of the box body 1. The movement of the cleaning platform 123 drives the scraping platform 126 to move synchronously to clean the dust on the top of the scraper 122. When the scraper 122 moves downward, the scraping platform 126 loses the contact force, and the spring drives the scraping platform 126 to automatically reset. When the scraping platform 126 resets, it returns the oil liquid inside the second oil chamber 127 to the first oil chamber 124. At this time, the oil liquid inside the second oil chamber 127 returns to its original state, causing the second piston rod 128 to drive the cleaning platform 123 to automatically reset.

[0022] Working principle: When the heat dissipation fins 3 absorb the heat generated inside the box body 1, the controller drives the fan 7 to work, and drives the screw rod inside the first adjustment table 6 to rotate through the motor. The screw rod drives the fan 7 to reciprocate inside the first housing 4 to evenly cool the heat dissipation fins 3. While the motor drives the screw rod inside the first adjustment table 6 to rotate, the controller will drive the screw rod inside the moving table 121 to reciprocate through the motor, driving the screw rod inside the moving table 121 to reciprocate, and driving the scraper 122 to move on the surface of the cover plate 11. When the scraper 122 touches the scraping table 126, at this time the scraping table 126 squeezes the first piston rod 125 to inject the oil liquid inside the first oil chamber 124 into the second oil chamber 127. The increased oil liquid inside the second oil chamber 127 squeezes the second piston rod 128, causing the second piston rod 128 to extend from the inside of the second oil chamber 127. The extension of the second piston rod 128 drives the cleaning table 123 to slide in a limited manner in the bottom groove of the box body 1. The movement of the cleaning table 123 drives the scraping table 126 to move synchronously to clean the dust on the top of the scraper 122. When the scraper 122 moves downward, the scraping table 126 loses the resistance, and the spring drives the scraping table 126 to automatically reset. When the scraping table 126 resets, it transports the oil liquid inside the second oil chamber 127 back to the first oil chamber 124. At this time, the oil liquid inside the second oil chamber 127 returns to its original state, causing the second piston rod 128 to drive the cleaning table 123 to automatically reset; When the surface temperature sensor of the fan 7 detects local high temperature on the heat dissipation fins 3, the controller drives the extending end of the first electric push rod 8 to push the adjusting plate 9 to move at the bottom of the first housing 4, so that the ventilation holes inside the adjusting plate 9 gradually coincide with the ventilation holes inside the first housing 4. After the motor drives the screw rod inside the first adjustment table 6 to drive the fan 7 to rotate to the high temperature area, at this time the motor at the side end of the first adjustment table 6 stops working. While the motor at the side end of the first adjustment table 6 stops working, the controller drives the motor to drive the screw rod inside the second adjustment table 108 to rotate. The rotation of the screw rod drives the baffle 109 to move until the baffle 109 moves to block the ventilation holes near the high temperature area, and then the motor at the side end of the second adjustment table 108 stops operating. At the same time, the controller drives the extending end of the second electric push rod 106 to extend to drive the rack 107 to move downward. When the rack 107 moves downward, it drives the first gear 104 and the second gear 105 to rotate synchronously. When the first gear 104 rotates, it drives the rotating plate 101 to rotate. At this time, the extension plate 102 inside the rotating plate 101 slides in a limited manner in the arc-shaped groove at the side end of the first housing 4. When the rotating plate 101 rotates 90°, the extension plate 102 extends out of the rotating plate 101 to block the cavity at the side end of the first housing 4. When the second gear 105 rotates, it drives the opening and closing plate 103 to rotate to open the notch at the bottom end of the first housing 4. The airflow generated by the fan 7 is blocked by the rotating plate 101 and the extension plate 102 and enters the second housing 5 from the notch at the bottom end of the first housing 4, and then is discharged through the ventilation holes inside the first housing 4 and the adjusting plate 9. While locally cooling the heat dissipation fins 3, it can clean the dust attached to the surface of the heat dissipation fins 3.
