Description

Technical Field

[0001] This utility model belongs to the field of cold aisle technology for data centers, specifically a horizontal sliding type electrically reset cold aisle skylight. Background Technology

[0002] Currently, cold aisle systems are one of the main solutions to address the challenging issues of high energy consumption, localized hotspots, and security protection in data center server rack clusters. Skylights are a key component of cold aisle systems. Traditional skylights have a tilting structure, utilizing gravity and electromagnetic locks to close and open. When the skylight opens, the heavier side moves downwards and the lighter side moves upwards. If there are obstacles of insufficient height above the skylight's trajectory or a tall person standing below, collisions can easily occur, causing injury or equipment damage. Furthermore, the open skylight is located in the middle of the frame, making it difficult for personnel to pass through to inspect equipment above, and also hindering the rapid entry of fire suppression gases into the aisle. In addition, since the closing of the skylight relies on the magnetic force of the electromagnetic lock, there are high technical requirements for the reliability of the electromagnetic lock and the stability of the skylight frame structure. When the magnetic force is insufficient to resist the gravity of the skylight, the skylight will open on its own. Data center server rooms are generally unattended for long periods of time, and the skylight opening on its own may not be discovered until much later. This will lead to an increase in air conditioning cooling capacity and increased energy consumption in the server room, which also violates the original intention of building a cold aisle system.

[0003] In view of this, a horizontal sliding type electrically reset cold aisle skylight is proposed. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given the following technical problems in the existing technology: the traditional up-and-down flip-up skylight has high requirements for the height of the cold aisle, inconvenience for personnel passage, difficulty in the entry of fire-fighting gases, and the risk of self-opening;

[0006] A horizontal sliding type electrically reset cold aisle skylight is proposed. It uses a motor to drive gears and a rubber transmission belt to move, and then the rubber transmission belt drives the skylight to move horizontally reciprocally along the width of the aisle. This significantly reduces the height requirements of the cold aisle when the skylight is opened, while also facilitating personnel passage, allowing fire-fighting gases to enter the aisle, and eliminating the risk of cold air leakage from the upper part of the cold aisle after the skylight opens on its own. This contributes to the energy conservation and emission reduction goals of the computer room.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a horizontal sliding type electrically reset cold aisle skylight, including a cabinet body, a skylight sliding guide rail and a gear fixing plate;

[0008] The sunroof sliding guide rail is mounted on a pair of cabinet bodies, and the gear fixing plate is located on the central axis of the pair of sunroof sliding guide rails;

[0009] The gear fixing plate is equipped with a driving gear, a driven gear, and a motor mounting plate. The motor mounting plate is installed on the top surface of one end of the gear fixing plate, and a motor is installed on the motor mounting plate. The motor and the driving gear are connected by a positioning pin shaft. The driving gear and the driven gear are connected and driven by a rubber transmission belt. A sunroof fixing component is clamped on the rubber transmission belt, and a sunroof is installed on the sunroof fixing component. The two are connected by screws, and the two sides of the sunroof are connected to the inner edge of the sunroof sliding guide rail.

[0010] As a preferred technical solution for a horizontally sliding, electrically reset cold aisle skylight, the gear fixing plate is mounted on the cabinet body, and the number of gear fixing plates is one pair.

[0011] As a preferred technical solution for a horizontally sliding, electrically reset cold aisle sunroof, the gear fixing plate is designed in an inverted π shape, and both ends of the gear fixing plate are equipped with press-fit studs. The gear fixing plate is equipped with a driving gear and a driven gear through the press-fit studs.

[0012] As a preferred technical solution for a horizontally sliding, electrically reset cold aisle sunroof, the top surface of the gear fixing plate is provided with a motor mounting plate fixing hole, the edge of the motor mounting plate is milled with a first fixing hole, the motor housing has a motor mounting ear, and the motor mounting plate is milled with a second fixing hole.

[0013] As a preferred technical solution for a horizontally sliding electric reset cold aisle sunroof, a positioning pin shaft is installed at the output position of the motor, a first circular hole with a thickness of half is opened on one side of the center position of the drive gear, the press-fit stud is inserted into the first circular hole, and a positioning pin hole with a thickness of half is opened on the other side of the center position of the drive gear, the positioning pin shaft is connected to the positioning pin hole.

[0014] As a preferred technical solution for a horizontally sliding, electrically reset cold aisle sunroof, the passive gear has a second circular hole with the same thickness as the passive gear in the center, and the press-fit stud is inserted into the second circular hole.

[0015] As a preferred technical solution for a horizontally sliding, electrically reset cold aisle sunroof, the sunroof fixing component is designed in a T-shape, with a belt groove at the end of the sunroof fixing component facing the rubber transmission belt, and a sunroof limiting groove on the upper surface of the sunroof fixing component.

[0016] The beneficial effects of this utility model are as follows: The horizontal sliding skylight can minimize the requirements for the height dimension of the cold aisle, reducing the risk of personnel injury and equipment damage; when the skylight is open, the top of the cold aisle can obtain the largest possible maintenance opening and facilitate the entry of fire-fighting gas into the aisle; the skylight can remain closed in the event of a power outage or equipment failure, ensuring that the cold aisle remains sealed and avoiding waste of cold air; the motor does not consume electrical energy when not running, thereby reducing the energy consumption of the cold aisle system and extending its service life; the opening and closing of the skylight are all controlled by the motor by the electronic control unit, eliminating the need for manual operation, reducing the workload of computer room maintenance personnel, and saving labor costs.
