Description

Technical Field

[0001] This utility model relates to the field of computer desks for computer rooms, specifically a computer desk for computer rooms. Background Technology

[0002] A computer room desk is a special workbench or rack designed specifically for data centers, server rooms, control centers, and other locations that require the centralized deployment and management of a large number of computer devices. It is fundamentally different from the computer desks we use in our daily offices or homes. Its core design philosophy is functionality, stability, heat dissipation, and manageability, rather than aesthetics or comfort. A computer room desk is a professional term; it does not refer to an isolated table, but rather a key component of the data center infrastructure. It aims to create an efficient, orderly, and secure working environment for IT administrators, ensuring that valuable servers and network equipment can be maintained in a timely and convenient manner, while maintaining the overall cleanliness and standardization of the data center. A computer room desk is a rack-mounted workbench specifically used for placing, organizing, and maintaining servers, network equipment, and other IT equipment within the data center. The existing authorization announcement number CN222091097U2 discloses a computer desk for a computer room, including a main body for placing a computer monitor and storing miscellaneous items, and a limiting device for supporting and restricting rotation located at the bottom rear of the main body. A rotating device is rotatably mounted on the top of the limiting device, allowing the computer host to be rolled and flipped out of its interface. The rotating device includes a host housing with a door on one side, an operating window at the top of the door, and a lock behind the operating window. This computer desk for a computer room, by allowing the host interface to be flipped out, not only facilitates the installation of the host but also the addition of peripherals; the rolling support for flipping makes the flipping smoother and facilitates the removal of the host; and the rotation-restricting device ensures stability during use. Existing computer desks for computer rooms have the following problems: When using a computer desk in a computer room, the computer host will emit a lot of heat inside the chassis. The heat will be trapped inside the chassis and cannot be effectively and quickly dissipated through the heat dissipation holes on the outer surface of the chassis. Therefore, we propose a new type of computer desk for computer rooms. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a computer desk for computer rooms. When using the computer desk, the heat will be discharged efficiently and quickly through active and passive heat dissipation, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a computer desk for a computer room, including a placement rack, a support plate at the upper end of the placement rack, a chassis inside the rear side of the placement rack, a mounting rack at the rear end of the placement rack, and a heat dissipation mechanism; The heat dissipation mechanism includes a rotating shaft, guide vanes, exhaust fans, sprockets, chains, and a protective cover. The rotating shaft is rotatably connected to the front side between the upper and lower inner walls of the mounting frame. Guide vanes are fixedly fitted in the middle of the rotating shaft. Exhaust fans are installed at the air inlets at the rear end of the mounting frame. Two sprockets are fixedly fitted at the lower end of the rotating shaft. The two sprockets, which are laterally adjacent and at the same level, are connected by chain drive. A protective cover is installed at the lower end of the mounting frame. The sprockets and chains are located inside the protective cover. When using the computer desk in the computer room, the hot air will be efficiently and quickly discharged through active and passive heat dissipation.

[0005] Furthermore, a control switch group is provided on the left side of the front end of the chassis. The input end of the control switch group is electrically connected to an external power source, and the input end of the exhaust fan is electrically connected to the output end of the control switch group, providing electrical connections for various electrical components.

[0006] Furthermore, the heat dissipation mechanism also includes a drive assembly, which includes a gear, a rotating column, a bracket, a one-third gear ring, and a half gear. The gear is fixedly connected to the lower end of the central rotating shaft. The rotating column is rotatably connected to the middle of the lower end of the protective cover. The bracket is fixedly fitted on the middle of the outer surface of the rotating column. The one-third gear ring is fixedly fitted on the outer surface of the bracket. The half gear is fixedly fitted on the outer surface of the rotating column. The one-third gear ring and the half gear are both installed in conjunction with the gear to provide a transmission connection.

[0007] Furthermore, the drive assembly also includes a motor and a circular cover. The circular cover is located in the middle of the lower end of the protective cover, and the motor is located at the lower end of the circular cover. The upper end of the output shaft of the motor is fixedly connected to the lower end of the rotating column, and the input end of the motor is electrically connected to the output end of the control switch group to provide rotation drive.

[0008] Furthermore, the upper rear side of the support plate is provided with symmetrical cable routing ports to facilitate cable routing.

[0009] Furthermore, a door is hinged to the center of the front end of the chassis, facilitating the installation of the computer host.

[0010] Furthermore, the outer surface of the chassis and the outer surface of the chassis door are respectively provided with evenly distributed heat dissipation holes to facilitate heat dissipation.

[0011] Compared with the prior art, the beneficial effects of this utility model are: this computer desk for the computer room has the following advantages: Driven by the motor, the rotating column drives the one-third gear ring and the half gear to rotate. When the one-third gear ring meshes with the gear, the gear rotates clockwise; when the half gear meshes with the gear, the gear rotates counterclockwise. This causes the rotating shaft to rotate in both directions. The rotating shaft, through the transmission of sprockets and chains, drives the other rotating shafts to adjust the tilt angle of the guide vanes. By changing the angle and controlling the direction, it adapts to the heat dissipation needs of different areas of the chassis. Driven by the exhaust fan, negative pressure is formed through active air extraction. External cold air is drawn in from the air inlet, guided by the guide vanes, and precisely blown to the location of the chassis to exchange heat with the heat-generating components inside the chassis, carrying away the heat. When using a computer desk in the computer room, the hot air is efficiently and quickly expelled through the coordinated active and passive heat dissipation. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-9 This embodiment provides a technical solution: a computer desk for a computer room, including a placement rack 1, a support plate 2 at the upper end of the placement rack 1, a chassis 3 inside the rear side of the placement rack 1, a mounting rack 4 at the rear end of the placement rack 1, and a heat dissipation mechanism 5. A control switch group 8 is provided on the left side of the front end of the chassis 3. The input end of the control switch group 8 is electrically connected to the external power supply, and the input end of the exhaust fan 53 is electrically connected to the output end of the control switch group 8 to ensure the electrical connection of each electrical appliance. Cooling mechanism 5 includes a rotating shaft 51, guide vanes 52, exhaust fans 53, sprockets 54, chains 55, and a protective cover 56. The rotating shaft 51 is rotatably connected to the front side between the upper and lower inner walls of the mounting bracket 4. Guide vanes 52 are fixedly fitted onto the middle part of the rotating shaft 51. Exhaust fans 53 are respectively installed at the air inlets at the rear end of the mounting bracket 4. Two sprockets 54 are fixedly fitted onto the lower end of the rotating shaft 51. The two sprockets 54, which are laterally adjacent and located at the same level, are connected by chains 55. The lower end of frame 4 is equipped with a protective cover 56. The sprocket 54 and chain 55 are both located inside the protective cover 56. (The protective cover 56 encloses the sprocket 54, chain 55, and other transmission components to prevent dust accumulation from affecting transmission accuracy and to avoid accidental contact with moving parts, thus preventing safety risks.) Through the engagement of the one-third gear ring 574 and the half-gear 575 with the gear 571, the central rotating shaft 51 will rotate. The lower end of the central rotating shaft 51 is fixed with a sprocket 54, which is connected to the adjacent lateral shaft via a chain 55. Furthermore, the sprockets 54 of other rotating shafts 51 at the same level form a transmission connection, ultimately driving all rotating shafts 51 to rotate synchronously. A guide vane 52 is fixedly sleeved in the middle of each rotating shaft 51. When the rotating shaft 51 rotates, the guide vane 52 adjusts its tilt angle synchronously. By changing the angle, the direction of airflow entering the mounting bracket 4 can be controlled to adapt to the heat dissipation needs of different areas of the chassis 3. The exhaust fan 53 is installed at the air inlet at the rear end of the mounting bracket 4. Then, by controlling the control switch group 8, the exhaust fan 53 operates and forms a negative pressure through active air extraction. External cold air is drawn in from the air inlet at the rear end of the mounting bracket 4, guided by the guide vane 52, and precisely blown to the position of the chassis 3 to exchange heat with the heat-generating components inside the chassis 3, carrying away the heat. Finally, the hot air is discharged from other gaps or heat dissipation holes 9 in the chassis 3, completing the cycle of cold air absorption and heat dissipation. The heat dissipation holes 9 on the outer surface of the chassis 3 and the chassis door 7 form a passive heat dissipation channel. On the one hand, it cooperates with the cold air drawn in by the exhaust fan 53 to enter the chassis 3, and on the other hand, it can naturally dissipate some heat, complementing the active heat dissipation. The heat dissipation mechanism 5 also includes a drive assembly 57, which includes a gear 571, a rotating column 572, a bracket 573, a one-third gear ring 574, and a half gear 575. The gear 571 is fixedly connected to the lower end of the central rotating shaft 51. The rotating column 572 is rotatably connected to the middle of the lower end of the protective cover 56. The bracket 573 is fixedly sleeved on the middle of the outer surface of the rotating column 572. The one-third gear ring 574 is fixedly sleeved on the outer surface of the bracket 573. The half gear 575 and the one-third gear ring are fixedly sleeved on the outer surface of the rotating column 572. Gears 574 and 575 are both installed in conjunction with gear 571. The drive assembly 57 also includes a motor 576 and a circular cover 577. The circular cover 577 is located in the middle of the lower end of the protective cover 56, and the motor 576 is located at the lower end of the circular cover 577. The upper end of the output shaft of the motor 576 is fixedly connected to the lower end of the rotating column 572. The input end of the motor 576 is electrically connected to the output end of the control switch group 8. Then, when the computer host is running, a large amount of heat will be generated. The heat will be dissipated by the heat sink built into the computer host, and the heat will remain inside the chassis 3. Then, by regulating the control switch group 8, the motor 576 operates. The output shaft of the motor 576 drives the lower rotating column 572 to rotate. The one-third gear ring 574 and the half gear 575 rotate synchronously with the rotating column 572. The one-third gear ring 574 and the half gear 575 alternately mesh with the gear 571 at the lower end of the central rotating shaft 51. When the one-third gear ring 574 meshes with the gear 571, it drives the gear 571 to rotate clockwise around the central rotating shaft 51. When the one-third gear ring 574 disengages, the half gear... 575 then meshes with gear 571, causing gear 571 to rotate counterclockwise around the central axis 51. The two states alternate. (The number of teeth on the one-third gear ring 574 is equal to the number of teeth on the half gear 575, and the number of teeth on gear 571 is equal to (the number of teeth on the one-third gear ring 574 and the number of teeth on the half gear 575 * 2). Therefore, when the one-third gear ring 574 meshes with gear 571, it causes gear 571 to rotate 180 degrees clockwise, and when the half gear 575 meshes with gear 571, it causes gear 571 to rotate 180 degrees counterclockwise.) The support plate 2 has symmetrical ribbon cable ports 6 on the rear side of the upper end. Then, place the monitor on the upper end of the support plate 2, and then pass the connecting cable through the ribbon cable port 6 to connect the computer host and the monitor. The front of the chassis 3 is hinged to the middle of the door 7. The outer surface of the chassis 3 and the outer surface of the door 7 are respectively provided with evenly distributed heat dissipation holes 9. When using the computer desk in the computer room, first open the door 7, and then place the computer host inside the chassis 3.

[0016] The working principle of the computer desk in the computer room provided by this utility model is as follows: When using the computer desk, first open the door 7, then place the computer host inside the chassis 3, then place the monitor on the upper end of the support plate 2, then pass the connecting cable through the ribbon cable port 6 to connect the computer host and the monitor. When the computer host is running, it will generate a lot of heat, which will be dissipated by the heat sink built into the computer host. The heat will remain inside the chassis 3, and then, through the control switch group 8, the motor 576 will operate. The output shaft of the motor 576 drives the lower rotating column 572. The gears rotate synchronously with the rotating column 572, with the one-third gear ring 574 and the one-half gear 575 meshing alternately with the gear 571 at the lower end of the central rotating shaft 51. When the one-third gear ring 574 meshes with the gear 571, it drives the gear 571 to rotate clockwise around the central rotating shaft 51. When the one-third gear ring 574 disengages, the one-half gear 575 immediately meshes with the gear 571, driving the gear 571 to rotate counterclockwise around the central rotating shaft 51. These two states alternate. The engagement of gears 575 and 571 drives the central rotating shaft 51 to rotate. A sprocket 54 is fixed to the lower end of the central rotating shaft 51. A chain 55 connects the central shaft 51 to the sprockets 54 of other horizontally adjacent rotating shafts 51, forming a transmission connection. This ultimately drives all rotating shafts 51 to rotate synchronously. A guide vane 52 is fixedly fitted in the middle of each rotating shaft 51. As the rotating shaft 51 rotates, the guide vane 52 adjusts its tilt angle accordingly. By changing the angle, the airflow direction entering the mounting bracket 4 can be controlled, adapting to the heat dissipation needs of different areas of the chassis 3. The exhaust fan 53 is installed at the rear end of the mounting bracket 4. At the air inlet, the fan 53 will operate by controlling the control switch group 8. The negative pressure is formed by active ventilation, and external cold air is drawn in from the air inlet at the rear end of the mounting bracket 4. After being guided by the guide vane 52, it is precisely blown to the position of the chassis 3, where it exchanges heat with the heat-generating components inside the chassis 3, carrying away the heat. Finally, the hot air is discharged from other gaps or heat dissipation holes 9 in the chassis 3, completing the cycle of cold air intake and heat exhaust. The heat dissipation holes 9 on the outer surface of the chassis 3 and the chassis door 7 form a passive heat dissipation channel. On the one hand, it works with the cold air drawn in by the fan 53 to enter the chassis 3, and on the other hand, it can naturally exhaust some heat, complementing the active heat dissipation.

[0017] It is worth noting that in the above embodiments, the exhaust fan 53 and the motor 576 disclosed can both be SF8025, the exhaust fan 53 can be RS-555, and the control switch group 8 is provided with switch buttons that correspond one-to-one with the exhaust fan 53 and the motor 576 and are used to control their switching operation.

[0018] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
