Description

Technical Field

[0001] This invention relates to the field of server rack technology, specifically to a server rack cooling device and server rack. Background Technology

[0002] A server rack is a freestanding or self-supporting enclosure used to house electrical or electronic equipment. Server racks typically feature doors, removable or non-removable side panels, and a back panel. They are an indispensable component of electrical equipment and serve as the carrier for electrical control devices. They are generally made of cold-rolled steel or alloy steel. They provide protection against water, dust, and electromagnetic interference for the stored equipment. Servers, switches, power supplies, and other equipment inside the rack generate a significant amount of heat during operation. If this heat accumulates, the temperature can rise rapidly. Installing a cooling air conditioner inside the rack actively cools the equipment and maintains the internal temperature within a controllable range, preventing overheating that could lead to equipment throttling, restarting, or damage.

[0003] However, when fixing the cooling air conditioner to the cabinet, the operator needs to lift the air conditioner by hand to align the mounting holes on the air conditioner with the mounting holes on the cabinet. During the lifting process, the hand will shake, which slows down the alignment of the mounting holes, making it more difficult to fix the air conditioner and does not reduce the workload of the operator. In addition, when the cooling air conditioner is installed too high, the downward flow of cold air is obstructed, and the equipment installed at the bottom of the cabinet cannot be adequately cooled, which can easily cause the temperature at the bottom of the cabinet to be too high, which is not conducive to improving the heat dissipation effect of the equipment. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a cooling device for a server rack and a server rack.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a cooling device and a cabinet, including a cabinet body, on which a cooling air conditioner is fixedly installed; two support mechanisms are symmetrically fixed on the side wall of the cabinet body near the cooling air conditioner; and two ventilation mechanisms are connected to the cabinet body.

[0006] Specifically, the support mechanism includes fixed frames and insertion holes. Two fixed frames are symmetrically fixedly installed on the side wall of the cabinet near the cooling air conditioner. Several insertion holes are equidistantly arranged on the fixed frames. Insert rods are engaged at the insertion holes. Limit blocks are threadedly installed at the ends of the insertion rods. Brackets are fixedly connected to the insertion rods. The bottom end of the cooling air conditioner contacts the brackets. A locking block is fixedly installed on the brackets and is engaged with the fixed frames. A connecting rod is fixedly installed on the locking block. A sleeve rod is slidably connected to the connecting rod. The end of the sleeve rod away from the connecting rod is engaged with the insertion rod. A protective cover is engaged with the limit block and the connecting rod. The insertion rod is engaged with the fixed frames. The end of the sleeve rod away from the connecting rod contacts the end of the limit block. The support mechanism also includes slots. Two sets of slots are symmetrically arranged on both sides of the protective cover. The protective cover abuts against the side wall of the cabinet.

[0007] Specifically, the ventilation mechanism includes a ventilation screen and a connecting shaft. Ventilation screens are fixedly installed on both sides of the cabinet. A connecting shaft is rotatably installed on the ventilation screen. A sealing plate is fixedly connected to the connecting shaft. An installation block is fixedly connected to the inner wall of the cabinet away from the ventilation screen.

[0008] Specifically, a drive mechanism is rotatably mounted inside the mounting block. The drive mechanism includes a rotating rod and a chuck. The rotating rod and the chuck are fixedly connected to the connecting shaft. A motor is fixedly mounted on the mounting block. The output end of the motor is fixedly connected to a rotating shaft via a coupling. A turntable is fixedly mounted on the rotating shaft. A stop rod is fixedly connected to the turntable, and the turntable and the chuck are rotatably connected. The rotating shaft, connecting shaft, and sealing plate are all rotatably connected to the mounting block. The contact area between the chuck and the turntable has a serrated structure. The ventilation mesh is connected to the interior of the cabinet through the mounting block. The motor is located on the side wall of the mounting block away from the ventilation mesh.

[0009] Specifically, an installation mechanism is fixed inside the cabinet. The installation mechanism includes a vertical pole and a fixing block. Two sets of fixing blocks are fixedly connected inside the cabinet. A vertical pole is fixedly installed on the fixing block. The vertical pole has a slot. A locking plate is installed in the slot. Several slots are equidistantly arranged on the side wall of the vertical pole away from the fixing block. The part where the locking plate engages with the vertical pole has an inclined structure. The installation mechanism also includes a sealing gasket. A sealing gasket is adhered to the part of the cabinet near the cooling air conditioner, and the sealing gasket is in contact with the cooling air conditioner.

[0010] The beneficial effects of this invention are:

[0011] (1) The cooling device and cabinet of the present invention fixes the support mechanism to the back of the cabinet. When installing the cooling air conditioner, it is placed on the support mechanism, which can support the operator when fixing the cooling air conditioner to the cabinet, which helps to reduce the burden of the operator lifting the cooling air conditioner. That is, the operator can use the fixing bolts to symmetrically install two fixing brackets on the back of the cabinet, and then insert the plug rod on the bracket into the plug hole provided in the fixing bracket. Since several plug holes are equidistantly arranged, the height of the bracket can be adjusted according to the required fixing height of the cooling air conditioner. When the plug rod is inserted into the fixing bracket and the bracket is in contact with the fixing bracket, the bracket can be rotated, and the bracket drives the locking block fixed on the side wall to rotate. The mechanism rotates, allowing the locking block to engage with the fixed frame, facilitating quick installation of the bracket. A connecting rod is fixed to the locking block, and a sleeve rod mounted on the side wall of the sliding connecting rod moves to contact the end of the connecting rod away from the locking block. This sleeve rod can then be sleeved onto the side wall of the insertion rod, pushing it towards the fixed frame until it contacts the side wall of the locking block. At this point, a limit block is threaded onto the end of the insertion rod to secure the sleeve rod, thus improving the stability of the bracket. The cooling air conditioner is placed on top of the two brackets, providing support. This ensures stability when the operator installs the cooling air conditioner into the cabinet using fixing bolts, reducing the workload of manually lifting the cooling air conditioner.

[0012] (2) The cooling device and cabinet of the cabinet described in this invention, through the installation mechanism, allows the height of the installation mechanism to be adjusted according to the size of the electrical components when installing electrical components into the cabinet, which is beneficial to improving the utilization efficiency of the cabinet. That is: when installing electrical components into the cabinet, the height of the card plate can be adjusted according to the size of the electrical components. Two sets of fixing blocks are installed in the cabinet, and the fixing blocks are fixed together with the uprights, so that the uprights can be installed in the cabinet. Align the two ends of the card plate with the card slots provided in the uprights, and push the card plate towards the cooling air conditioner, so that the card plate and the uprights can be engaged and connected, thereby allowing the uprights to support the card plate. The part of the card plate that contacts the uprights is set with a sloping structure, which can increase the contact area between the card plate and the uprights, thereby making the card plate support the electrical components better.

[0013] (3) The cooling device and cabinet of the present invention, during the use of the cabinet, the ventilation mechanism is driven by the drive mechanism to rotate, so that the outside air is discharged into the cabinet through the ventilation mechanism, which is conducive to improving the air circulation at the bottom of the cabinet. That is, during the use of the cabinet, when the heat at the bottom of the cabinet increases, the motor switch fixed on the mounting block can be turned on, the motor drives the rotating shaft to rotate in the mounting block, the rotating shaft drives the turntable fixed on the side wall to rotate, during the rotation of the turntable, the abutment fixed on the top can abut against the rotating rod installed on the connecting shaft when rotating with the turntable, the abutment pushes the rotating rod to rotate, so that the chuck fixed on the connecting shaft... As the turntable rotates along its side wall, when the groove inside the turntable engages with the protrusion on the chuck, the turntable drives the chuck to rotate. The connecting shaft is fixed together with the sealing plate. After the rotating rod drives the connecting shaft to rotate 180 degrees, the connecting shaft drives the sealing plate to rotate 180 degrees. The sealing plate rotates along the ventilation mesh installed inside the cabinet. When the sealing plate and the ventilation mesh are perpendicular, the ventilation mesh can connect with the inside of the cabinet, allowing hot air at the bottom of the cabinet to be discharged through the ventilation mesh, and allowing cold air from the outside to be introduced into the cabinet through the ventilation mesh. This improves air circulation at the bottom of the cabinet and enhances the cabinet's heat dissipation effect. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the present invention provides a cooling device and cabinet for a server rack, comprising a cabinet body 1, on which a cooling air conditioner 3 is fixedly installed; two support mechanisms 5 are symmetrically fixed on the side wall of the cabinet body 1 near the cooling air conditioner 3; and two ventilation mechanisms 4 are connected to the cabinet body 1.

[0029] Specifically, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the support mechanism 5 includes a fixed frame 505 and insertion holes 506. Two fixed frames 505 are symmetrically fixedly installed on the side wall of the cabinet 1 near the cooling air conditioner 3. Several insertion holes 506 are equally spaced on the fixed frame 505. Insertion rods 509 are engaged in the insertion holes 506. Limiting blocks 502 are threaded onto the ends of the insertion rods 509. A bracket 508 is fixedly connected to the insertion rods 509. The fixed frame 505 is installed on the back of the cabinet 1 using fixing bolts, and then the insertion rods 509 are inserted into the fixed frame 505. Since the insertion holes 506 are equally spaced, they can be adjusted according to the cooling air conditioner 3. Adjustment 3 requires adjusting the height of the bracket 508 to a fixed height; the bottom end of the cooling air conditioner 3 contacts the bracket 508, placing the cooling air conditioner 3 on top of the two brackets 508 for support. This ensures the cooling air conditioner 3 is stable when installed in the cabinet 1 using fixing bolts, reducing the operator's workload in lifting the cooling air conditioner 3; a locking block 507 is fixedly installed on the bracket 508, and the locking block 507 engages with the fixing frame 505. The insertion rod 509 is inserted into the fixing frame 505, connecting the bracket 508 to the fixing frame 505. When the bracket 505 is in the abutting state, the bracket 508 can be rotated, causing the bracket 508 to rotate and the locking block 507 to engage with the fixed bracket 505 after rotation, thus facilitating the quick installation of the bracket 508. A connecting rod 504 is fixedly installed on the locking block 507, and a sleeve rod 510 is slidably connected to the connecting rod 504. The end of the sleeve rod 510 opposite to the connecting rod 504 is engaged with the insertion rod 509. A protective cover 501 is engaged on the limiting block 502 and the connecting rod 504. The protective cover 501 abuts against the side wall of the cabinet 1. The protective cover 501 is symmetrically arranged on both sides. There are two sets of slots 503. The insertion rod 509 is engaged with the fixing frame 505. The end of the sleeve rod 510 away from the connecting rod 504 contacts the end of the limiting block 502. When the sleeve rod 510 moves to abut against the end of the connecting rod 504 away from the locking block 507, the end of the sleeve rod 510 away from the connecting rod 504 can be sleeved onto the side wall of the insertion rod 509. Push the sleeve rod 510 towards the fixing frame 505 so that it contacts the side wall of the locking block 507. At this time, the limiting block 502 is threaded onto the end of the insertion rod 509 to fix the sleeve rod 510, thereby improving the stability of the bracket 508.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 9 , Figure 10 and Figure 11As shown, the ventilation mechanism 4 includes a ventilation mesh 401 and a connecting shaft 403. Ventilation meshes 401 are fixedly installed on both sides of the cabinet 1. The connecting shaft 403 is rotatably installed on the ventilation mesh 401. A sealing plate 404 is fixedly connected to the connecting shaft 403. An installation block 402 is fixedly connected to the inner wall of the cabinet 1 away from the ventilation mesh 401. The sealing plate 404 rotates along the ventilation mesh 401. When the sealing plate 404 and the ventilation mesh 401 are in a perpendicular state, the ventilation mesh 401 can be connected to the interior of the cabinet 1.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 7 , Figure 9 and Figure 10 As shown, a drive mechanism 6 is rotatably mounted inside the mounting block 402. The drive mechanism 6 includes a rotating rod 602 and a chuck 603. The rotating rod 602 and the chuck 603 are fixedly connected to the connecting shaft 403. A motor 601 is fixedly mounted on the mounting block 402. The output end of the motor 601 is fixedly connected to a rotating shaft 605 via a coupling. A turntable 606 is fixedly mounted on the rotating shaft 605. A stop rod 604 is fixedly connected to the turntable 606, and the turntable 606 is rotatably connected to the chuck 603. The rotating shaft 605, the connecting shaft 403, and the sealing plate 404 are all rotatably connected to the mounting block 402. The motor 601 drives the rotating shaft 605 to rotate within the mounting block 402. When the turntable 606 rotates, the abutment 604 fixed at the top of the turntable 606 can abut against the rotating rod 602 on the connecting shaft 403. The abutment 604 pushes the rotating rod 602 to rotate, causing the chuck 603 fixed on the connecting shaft 403 to rotate along the side wall of the turntable 606. When the groove provided in the turntable 606 engages with the protrusion on the chuck 603, the turntable 606 can drive the chuck 603 to rotate. After the rotating rod 602 drives the connecting shaft 403 to rotate 180 degrees, the connecting shaft 403 can drive the sealing plate 404 to rotate 180 degrees. The sealing plate 404 rotates along the ventilation mesh 401 installed in the cabinet 1. When the sealing plate 404 and the ventilation mesh 401 are in a perpendicular state, the ventilation mesh 401 can be connected to the interior of the cabinet 1.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, an installation mechanism 2 is fixed inside the cabinet 1. The installation mechanism 2 includes a vertical rod 201 and a fixing block 203. Two sets of fixing blocks 203 are fixedly connected inside the cabinet 1. The vertical rod 201 is fixedly installed on the fixing block 203. The vertical rod 201 is provided with a slot 204. A locking plate 202 is engaged in the slot 204. By aligning the two ends of the locking plate 202 with the slot 204 and pushing the locking plate 202 towards the cooling air conditioner 3, the locking plate 202 can be engaged with the vertical rod 201, thereby making the vertical rod 201... The card plate 202 is supported; several card slots 204 are equidistantly arranged on the side wall of the upright 201 away from the fixing block 203. The part of the card plate 202 that engages with the upright 201 is set with an inclined structure, which can increase the contact area between the card plate 202 and the upright 201, thereby making the supporting effect of the card plate 202 on the electrical components better; a sealing gasket 205 is adhered to the part of the cabinet 1 near the cooling air conditioner 3, and the sealing gasket 205 abuts against the cooling air conditioner 3. The setting of the sealing gasket 205 can improve the sealing between the cooling air conditioner 3 and the cabinet 1.

[0033] In use, the operator can use fixing bolts to symmetrically install two fixing brackets 505 on the back of the cabinet 1. Then, the insertion rod 509 on the bracket 508 is inserted into the insertion hole 506 in the fixing bracket 505. Since the insertion holes 506 are equidistantly arranged, the height of the bracket 508 can be adjusted according to the required fixing height of the cooling air conditioner 3. When the insertion rod 509 is inserted into the fixing bracket 505 and the bracket 508 is in contact with the fixing bracket 505, the bracket 508 can be rotated. The bracket 508 drives the locking block 507 fixed on the side wall to rotate, and the locking block 507 can engage with the fixing bracket 505 after rotation, thus facilitating the quick installation of the bracket 508. A connecting rod 504 is fixed on the locking block 507, which slides... When the sleeve rod 510 installed on the side wall of the connecting rod 504 moves to abut against the end of the connecting rod 504 away from the locking block 507, the end of the sleeve rod 510 away from the connecting rod 504 can be sleeved onto the side wall of the insertion rod 509. Push the sleeve rod 510 towards the fixing bracket 505 so that it contacts the side wall of the locking block 507. At this time, the limiting block 502 is threaded onto the end of the insertion rod 509 to fix the sleeve rod 510, thereby improving the stability of the bracket 508. The cooling air conditioner 3 is placed on top of the two brackets 508, so that the brackets 508 support it. In this way, when the operator installs the cooling air conditioner 3 in the cabinet 1 with fixing bolts, the cooling air conditioner 3 can be in a stable state, and the workload of the operator in lifting the cooling air conditioner 3 is also reduced.

[0034] When installing electrical components into cabinet 1, the height of the mounting plate 202 can be adjusted according to the size of the electrical components. Two sets of fixing blocks 203 are installed inside cabinet 1. The fixing blocks 203 are fixed together with the uprights 201, allowing the uprights 201 to be installed inside cabinet 1. Align the two ends of the mounting plate 202 with the slots 204 provided in the uprights 201, and push the mounting plate 202 towards the cooling air conditioner 3. This will allow the mounting plate 202 to engage with the uprights 201, thereby allowing the uprights 201 to support the mounting plate 202. The part of the mounting plate 202 that contacts the uprights 201 has an inclined structure, which can increase the contact area between the mounting plate 202 and the uprights 201, thereby making the support effect of the mounting plate 202 on the electrical components better.

[0035] During the use of cabinet 1, when the heat at the bottom of cabinet 1 increases, the switch of motor 601 fixed on mounting block 402 can be turned on. Motor 601 drives rotating shaft 605 to rotate within mounting block 402. Rotating shaft 605 drives turntable 606 fixed on the side wall to rotate. During the rotation of turntable 606, the abutment rod 604 fixed at the top can abut against rotating rod 602 mounted on connecting shaft 403 as it rotates with turntable 606. Abutment rod 604 pushes rotating rod 602 to rotate, causing chuck 603 fixed on connecting shaft 403 to rotate along the side wall of turntable 606. When the groove in turntable 606 engages with the protrusion on chuck 603, the turntable can rotate. The 606 drives the chuck 603 to rotate. The connecting shaft 403 is fixed together with the sealing plate 404. After the rotating rod 602 drives the connecting shaft 403 to rotate 180 degrees, the connecting shaft 403 can drive the sealing plate 404 to rotate 180 degrees. The sealing plate 404 rotates along the ventilation net 401 installed inside the cabinet 1. When the sealing plate 404 and the ventilation net 401 are in a perpendicular state, the ventilation net 401 can be connected to the inside of the cabinet 1. This allows hot air at the bottom of the cabinet 1 to be discharged through the ventilation net 401, and also allows cold air from the outside to be introduced into the cabinet 1 through the ventilation net 401. This helps to improve the air circulation at the bottom of the cabinet 1 and improve the heat dissipation effect of the cabinet 1.
