Description

Technical Field

[0001] This invention relates to the field of heat dissipation cabinet technology, and in particular to a double-layer airflow circulating heat dissipation cabinet. Background Technology

[0002] Server racks are widely used to install servers, switches, power distribution equipment, and communication equipment. The internal electronic components generate a lot of heat during operation. If the heat cannot be dissipated in time, the temperature inside the rack will rise, which will lead to a decrease in equipment performance, unstable operation, or even failure.

[0003] Currently, most server racks use natural heat dissipation methods such as front and rear ventilation or side openings. When cold air enters the rack, it easily mixes with hot air. The hot air stagnates in the upper part of the rack and forms eddies, resulting in uneven temperature distribution and excessively high temperatures in some areas, which affects the normal operation and lifespan of the equipment.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a double-layer airflow circulating heat dissipation cabinet. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a double-layer air duct circulating heat dissipation cabinet to solve the problem of uneven temperature distribution and excessively high temperature in local areas, which affects the normal operation and service life of the equipment.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0007] A dual-layer air duct circulating heat dissipation cabinet includes a main unit, a heat dissipation mechanism for dissipating heat inside the main unit, an airflow blowing mechanism for blowing airflow inside the main unit, and a circulation auxiliary mechanism for assisting airflow circulation.

[0008] The complete machine includes a cabinet, an installation plate is fixedly installed inside the cabinet, and support columns are fixedly installed at the four corners of the bottom of the installation plate. The support columns are fixedly connected to the bottom of the inner cavity of the cabinet, and the bottom of the installation plate is set as a grid.

[0009] The heat dissipation mechanism includes a motor, which is located at the bottom of the mounting plate. The motor is fixedly connected to a transmission shaft via an output shaft. Multiple first fan blades are fixedly mounted on the outside of the transmission shaft. The transmission shaft is rotatably connected to the bottom of the mounting plate via bearings. An active bevel gear is fixedly mounted on the outside of the transmission shaft. Multiple ventilation openings are provided on both sides of the mounting plate. Multiple semiconductor cooling chips are fixedly mounted inside the cabinet.

[0010] The airflow blowing mechanism includes multiple fixed seats, each of which is fixedly connected to the inner wall of the cabinet. Two opposite fixed seats are respectively located on one side of multiple ventilation openings. A guide shaft is rotatably connected between two fixed seats via bearings. Multiple first mounting brackets are fixedly mounted on the guide shaft. A first micro motor is fixedly mounted on one side of the first mounting bracket. The first micro motor is fixedly connected to a micro motor connecting shaft via an output shaft. Multiple second fan blades are fixedly mounted on the outside of the micro motor connecting shaft.

[0011] In order to solve the problem of power transmission from the active bevel gear to the horizontal shaft, a horizontal shaft is provided on both sides of the transmission shaft. The horizontal shaft is located at the top of multiple first fan blades. One end of the horizontal shaft is rotatably connected to the inner wall of the cabinet through a bearing. The other end of the horizontal shaft is fixedly provided with a driven bevel gear. The driven bevel gear is located on one side of the active bevel gear and meshes with the active bevel gear.

[0012] To address the issue of stable support for the horizontal axis, a connecting seat is rotatably connected to the outside of the horizontal axis via a bearing, and the top of the connecting seat is fixedly connected to the bottom of the mounting plate.

[0013] To address the issue of cam installation, a cam is fixedly mounted on the outside of the horizontal shaft. The cam is located near the side wall of the cabinet. Four vertical rods are fixedly mounted inside the cabinet, with each of the four vertical rods positioned at one of the four corners inside the cabinet.

[0014] To address the issue of rack and pinion lifting drive, a sliding sleeve is fitted around the outside of the vertical rod, and a rack is fixedly mounted on one side of the sliding sleeve. Two gears are fixedly mounted on the outside of each of the multiple guide shafts, and the gears are located on one side of the rack and mesh with it.

[0015] In order to solve the problem of stable lifting of the lifting plate, a lifting plate is fixed between the two opposing sliding sleeves. The lifting plate is located on the top of the cam and contacts the cam.

[0016] To address the installation issue of the top circulation mechanism, the circulation auxiliary mechanism includes two fixed shafts, which are respectively located on both sides of the top of the cabinet's inner cavity. Each fixed shaft has an ear plate fixedly attached to both ends, and the top of the ear plate is fixedly connected to the top of the cabinet's inner cavity.

[0017] To address the issue of top airflow circulation drive, multiple second mounting brackets are fixedly mounted on one side of the fixed shaft, and a second micro motor is fixedly mounted on one side of the second mounting bracket. The second micro motor is fixedly connected to a rotating rod via an output shaft, and multiple third fan blades are fixedly mounted on the outside of the rotating rod.

[0018] To address the issue of installing the bottom motor, support legs are fixedly installed at all four corners of the bottom of the cabinet, and a motor mounting base is fixedly installed at the bottom of the cabinet, with the motor fixedly mounted on top of the motor mounting base.

[0019] To address the issue of centralized control, the cabinet is equipped with two doors via hinges, each with a handle. One of the doors is equipped with a programmable controller, which is electrically connected to a motor, a semiconductor cooling chip, multiple first micro motors, and multiple second micro motors.

[0020] The above technical solution has the following beneficial effects:

[0021] 1. This invention creates a double-layer air duct between the mounting plate and the cabinet by setting an installation plate inside the cabinet. A structure with a motor, drive shaft and first fan blade is set at the bottom of the mounting plate. The airflow enters the air duct through the bottom mesh of the mounting plate and is sent into the cabinet through the ventilation port, thereby transporting the heat generated by the electronic components upward and carrying it out, reducing the retention of hot air in the cabinet.

[0022] 2. This invention drives the active and driven bevel gears to rotate via the transmission shaft, causing the horizontal shaft and cam to rotate and push the lifting plate to move up and down. Then, through the meshing of the rack and gear, the guide shaft is driven to reciprocate in both forward and reverse directions, so that the blowing direction of the second fan blade is constantly changed. This allows for multi-angle airflow to dissipate heat from electronic components in different locations inside the cabinet, reducing the risk of local overheating.

[0023] 3. This invention cools the surrounding airflow by installing a semiconductor cooling chip inside the cabinet, and blows the air inside the cabinet back into the air duct through the third fan blade at the top to form a closed loop, so that the cold air continues to circulate inside the cabinet, thereby improving the overall heat dissipation efficiency and uniformity, and ensuring the normal operation and service life of the electronic components inside the cabinet.

[0038] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] See Figures 1-8 As shown, a double-layer air duct circulating heat dissipation cabinet of the present invention includes a whole unit 1, a heat dissipation mechanism 2 for dissipating heat inside the whole unit 1, an airflow blowing mechanism 3 for blowing airflow inside the whole unit 1, and a circulation auxiliary mechanism 4 for assisting airflow circulation.

[0040] The complete machine mechanism 1 includes a cabinet 101, an installation plate 106 is fixedly installed inside the cabinet 101, and support columns 107 are fixedly installed at the four corners of the bottom of the installation plate 106. The support columns 107 are fixedly connected to the bottom of the inner cavity of the cabinet 101, and the bottom of the installation plate 106 is set as a grid.

[0041] The heat dissipation mechanism 2 includes a motor 201, which is located at the bottom of the mounting plate 106. The motor 201 is fixedly connected to a transmission shaft 202 via an output shaft. Multiple first fan blades 206 are fixedly mounted on the outside of the transmission shaft 202. The transmission shaft 202 is rotatably connected to the bottom of the mounting plate 106 via bearings. An active bevel gear 207 is fixedly mounted on the outside of the transmission shaft 202. Multiple ventilation openings 204 are opened on both sides of the mounting plate 106. Multiple semiconductor cooling chips 203 are fixedly mounted inside the cabinet 101.

[0042] The cabinet 101 is fixedly provided with support legs 102 at the four corners of the bottom, and a motor mounting base 205 is fixedly provided at the bottom of the cabinet 101. The motor 201 is fixedly provided on the top of the motor mounting base 205.

[0043] The cabinet 101 is provided with two cabinet doors 105 via hinges. A handle 103 is fixedly provided on the cabinet door 105. A programmable controller 104 is provided on one of the cabinet doors 105. The programmable controller 104 is electrically connected to a motor 201, a semiconductor cooling chip 203, a plurality of first micro motors 313 and a plurality of second micro motors 403.

[0044] Working principle:

[0045] When using this invention, electronic components can be placed on the cabinet 101 and the mounting plate 106 inside the cabinet 101. Then, the motor 201 and the thermoelectric cooler 203 can be controlled by the programmable controller 104. The operation of the motor 201 drives the drive shaft 202 to rotate, and the rotation of the drive shaft 202 drives the first fan blade 206 to rotate. The rotation of the first fan blade 206 can generate wind power, which is transmitted to the inside of the cabinet 101 through the mesh on the mounting plate 106. At the same time, the airflow can also enter the air duct between the cabinet 101 and the mounting plate 106 through the bottom sides of the mounting plate 106. Then, the airflow can be transmitted to the inside of the cabinet 101 through the vent 204. The operation of the thermoelectric cooler 203 can cool the airflow around the thermoelectric cooler 203, so that the cooler airflow can be blown into the inside of the cabinet 101 through multiple second fan blades 315.

[0046] The airflow blowing mechanism 3 includes multiple fixed seats 306, all of which are fixedly connected to the inner wall of the cabinet 101. Two opposite fixed seats 306 are respectively located on one side of multiple ventilation openings 204. A guide shaft 310 is rotatably connected between the two fixed seats 306 through a bearing. Multiple first mounting brackets 312 are fixedly mounted on the guide shaft 310. A first micro motor 313 is fixedly mounted on one side of the first mounting bracket 312. The first micro motor 313 is fixedly connected to a micro motor connecting shaft 314 through an output shaft. Multiple second fan blades 315 are fixedly mounted on the outside of the micro motor connecting shaft 314.

[0047] A horizontal shaft 302 is provided on both sides of the drive shaft 202. The horizontal shaft 302 is located on the top of multiple first fan blades 206. One end of the horizontal shaft 302 is rotatably connected to the inner wall of the cabinet 101 through a bearing. The other end of the horizontal shaft 302 is fixedly provided with a driven bevel gear 301. The driven bevel gear 301 is located on one side of the driving bevel gear 207 and meshes with the driving bevel gear 207.

[0048] A connecting seat 303 is rotatably connected to the outside of the horizontal shaft 302 via a bearing, and the top of the connecting seat 303 is fixedly connected to the bottom of the mounting plate 106.

[0049] A cam 304 is fixedly provided on the outside of the horizontal axis 302. The cam 304 is located near the side wall of the cabinet 101. Four vertical rods 307 are fixedly provided inside the cabinet 101. The four vertical rods 307 are respectively located at the four corners inside the cabinet 101.

[0050] A sliding sleeve 308 is fitted on the outside of the vertical rod 307. A rack 309 is fixedly installed on one side of the sliding sleeve 308. Two gears 311 are fixedly installed on the outside of each of the multiple guide shafts 310. The gears 311 are located on one side of the rack 309 and mesh with the rack 309.

[0051] A lifting plate 305 is fixedly provided between two opposing sliding sleeves 308. The lifting plate 305 is located on the top of the cam 304 and contacts the cam 304.

[0052] Working principle:

[0053] Simultaneously, multiple first micro motors 313 can be controlled to work together via programmable controller 104. The operation of the first micro motors 313 drives the micro motor connecting shaft 314 to rotate. The rotation of the micro motor connecting shaft 314 drives multiple second fan blades 315 outside the micro motor connecting shaft 314 to rotate. The second fan blades 315 can blow the airflow in the air duct formed by the cabinet 101 and the mounting plate 106 into the cabinet 101. When the transmission shaft 202 rotates, it also drives the driving bevel gear 207 to rotate. The rotation of the driving bevel gear 207 drives the driven bevel gear 301 to rotate. The rotation of the driven bevel gear 301 drives the horizontal shaft 302 to rotate around the central axis of the horizontal shaft 302. The rotation of the horizontal shaft 302 drives the cam 304 to rotate. Because the cam 304 is in contact with the lifting plate 305, the cam 304 can continuously press against the lifting plate when it rotates. At the bottom of 305, due to the shape design of cam 304, when cam 304 rotates, it causes the lifting plate 305 at the top of cam 304 to move up and down. The movement of lifting plate 305 will drive the two sliding sleeves 308 to move up and down together. The movement of sliding sleeves 308 will drive the rack 309 to move. Because rack 309 meshes with gear 311, the movement of rack 309 will drive gear 311 to rotate. The rotation of gear 311 will drive guide shaft 310 to rotate around the central axis of guide shaft 310. Therefore, when lifting plate 305 moves up and down, guide shaft 310 will continuously rotate forward and reverse, thereby causing multiple first mounting brackets 312 and multiple first micro motors 313 on guide shaft 310 to rotate together. This can change the direction of airflow blown out by multiple second fan blades 315, and better dissipate heat from the electronic components inside cabinet 101.

[0054] The circulation auxiliary mechanism 4 includes two fixed shafts 404, which are respectively located on the top sides of the inner cavity of the cabinet 101. Ear plates 402 are fixedly provided at both ends of the fixed shafts 404, and the top of the ear plates 402 is fixedly connected to the top of the inner cavity of the cabinet 101.

[0055] A plurality of second mounting brackets 405 are fixedly provided on one side of the fixed shaft 404, and a second micro motor 403 is fixedly provided on one side of the second mounting bracket 405. The second micro motor 403 is fixedly connected to a rotating rod through an output shaft, and a plurality of third fan blades 401 are fixedly provided on the outside of the rotating rod.

[0056] Working principle:

[0057] The programmable controller 104 can control multiple second micro motors 403 to work together. The operation of the second micro motors 403 can drive the rotating rod to rotate, and the rotation of the rotating rod can drive multiple third fan blades 401 to rotate. The rotation of the third fan blades 401 can blow the air inside the cabinet 101 to the air duct between the cabinet 101 and the mounting plate 106, forming a closed loop.

[0058] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
