Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of computer room cooling technology, and more specifically, to an electrically retractable skylight for computer room cooling ducts. Background Technology

[0002] Traditional data centers mostly use natural ventilation or ordinary mechanical ventilation. Natural ventilation relies on the ventilation openings of the data center building and is greatly affected by outdoor climate conditions. In severe weather conditions such as high temperature and high humidity, it cannot effectively cool the data center and it is difficult to accurately control the ventilation volume and direction. Although ordinary mechanical ventilation uses equipment such as fans, the air outlets are fixed and the cold air is unevenly distributed, often leading to local overheating in the data center. In some large data centers, the corner areas are significantly hotter than other areas because it is difficult for cold air to reach them, resulting in frequent equipment failures. As data center construction moves towards higher integration and density, the requirements for ventilation and heat dissipation systems are becoming increasingly stringent. On the one hand, it is necessary to ensure that cool air can evenly and efficiently cover every corner of the data center to meet the heat dissipation needs of different devices. On the other hand, it is necessary to have intelligent adjustment functions to automatically adjust the ventilation status according to real-time environmental parameters in the data center and reduce energy consumption. Against this backdrop, the electric tilting skylight for data center cooling ducts has emerged. Through innovative circulating air supply components and intelligent and controllable air outlet tilting components, it provides a new and effective solution to the problem of data center ventilation and heat dissipation, aiming to break the limitations of traditional ventilation methods and ensure that the data center is always at a stable and suitable operating temperature in complex environments. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide an electrically reversible skylight for computer room cooling ducts, which solves the technical problems in the prior art where traditional computer rooms mostly use natural ventilation or ordinary mechanical ventilation. Natural ventilation relies on the ventilation openings of the computer room building, is greatly affected by outdoor climate conditions, and cannot effectively cool the computer room under harsh weather conditions such as high temperature and high humidity, and it is difficult to accurately control the ventilation volume and direction.

[0004] According to one aspect, at least one embodiment of this disclosure provides an electrically retractable skylight for a computer room cooling duct, including... A ventilation hood, wherein the side wall of the ventilation hood is provided with a mounting plate; An air outlet tilting assembly is disposed on the outer side wall of the air duct; A circulating air supply assembly is disposed on the air hood; The air outlet flipping assembly includes an air outlet, which is opened on the outer side wall of the air hood. A positioning shaft is provided on the inner side wall of the air hood, and a connecting sleeve is fitted on the positioning shaft. An air outlet plate is provided on the side wall of the connecting sleeve, and the air outlet is embedded inside the air outlet. The air outlet and the air outlet plate are sealed and fitted together. There are several air outlets, and several air outlets are evenly opened on the outer side wall of the air hood.

[0005] As a further technical solution, a drive disc is provided inside the air duct, and a connecting rod is connected to the side wall of the drive disc by a pin. The end of the connecting rod is connected to the air outlet plate by a pin.

[0006] As a further technical solution, the circulating air supply assembly includes an air inlet pipe, which is disposed on the upper end face of the air hood, and a connecting groove is provided at the end of the air inlet pipe.

[0007] As a further technical solution, the air hood has a U-shaped structure, and the air inlet pipes are arranged on opposite sides of the upper end face of the air hood. There are two air inlet pipes, and each of the two air inlet pipes has a connecting groove.

[0008] As a further technical solution, the two ends of the linkage are provided with through tubes, and the inside of the through tubes is provided with through shafts, which are connected to the drive disc by pins.

[0009] As a further technical solution, the side wall of the air outlet plate is provided with a mounting frame, and the mounting frame is connected to the through shaft by a pin.

[0010] As a further technical solution, a limiting plate is provided on the side wall of the positioning shaft, and the limiting plate is in contact with the connecting sleeve.

[0011] As a further technical solution, the air outlet plate has an arc-shaped structure, and the outer contour of the air outlet plate matches the outer contour of the air duct.

[0012] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the circulating air supply component adopts a dual-inlet duct design, with the inlet ducts distributed on opposite sides of the upper surface of the air hood. This allows cold air to enter the air hood more quickly and evenly, avoiding problems such as local cold air accumulation or insufficient supply. At the same time, several evenly distributed air outlets, together with a flip-out air outlet plate, can accurately deliver cold air to various areas of the computer room, including corners that are difficult to reach with traditional ventilation methods. This effectively solves the problem of local overheating, ensures that the equipment in the computer room is heated evenly, and significantly improves the overall heat dissipation efficiency. Through a linkage system composed of a drive plate, linkage rod, and other structures, the air outlet plate can be electrically flipped. This not only allows for quick control of the opening and closing of the air outlets but also precise adjustment of the flip angle of the air outlet plate, thereby flexibly changing the cold air volume and airflow direction. This precise control capability allows the computer room to make targeted adjustments according to the heat dissipation needs of different equipment and real-time temperature changes, meeting diverse ventilation requirements.

[0021] like Figures 1-3 As shown, it illustrates an electrically retractable skylight for a computer room cooling duct, comprising: The ventilation hood 1 has a mounting plate 2 on its side wall; Air outlet flip assembly 3 is disposed on the outer side wall of air duct 1; The circulating air supply component 4 is installed on the air hood 1; The air outlet flipping assembly 3 includes an air outlet 3-1, which is located on the outer side wall of the air hood 1. A positioning shaft 3-2 is provided on the inner side wall of the air hood 1. A connecting sleeve 3-3 is fitted on the positioning shaft 3-2. An air outlet plate 3-4 is provided on the side wall of the connecting sleeve 3-3. The air outlet plate 3-4 is embedded in the air outlet 3-1. The air outlet 3-1 and the air outlet plate 3-4 are sealed and fitted together. There are several air outlets 3-1, which are evenly distributed on the outer side wall of the air hood 1.

[0022] The circulating air supply assembly 4 includes an air inlet pipe 4-1, which is located on the upper surface of the air hood 1, and a connecting groove 4-2 is provided at the end of the air inlet pipe 4-1.

[0023] In some examples, air inlet pipes 4-1 are respectively installed on opposite sides of the upper end face of the hood 1, for a total of two air inlet pipes 4-1. A mounting plate 2 is installed on the side wall of the hood 1. The mounting plate 2 is used for subsequent installation of other related components, providing an installation foundation for the integration of the entire system. Its specific location and dimensions are precisely designed and manufactured according to the actual layout and installation requirements of the computer room. Several air outlets 3-1 are evenly opened on the outer side wall of the hood 1. These air outlets 3-1 provide channels for the cold air to flow out. A positioning shaft 3-2 is installed on the inner wall of the fan cover 1 corresponding to each air outlet 3-1. A connecting sleeve 3-3 is fitted onto the positioning shaft 3-2, and the connecting sleeve 3-3 can rotate flexibly on the positioning shaft 3-2. An air outlet plate 3-4 is installed on the side wall of the connecting sleeve 3-3. The air outlet plate 3-4 is embedded inside the air outlet 3-1, and the air outlet 3-1 and the air outlet plate 3-4 are sealed together to ensure that cold air can only flow out of the air outlet 3-1 through the adjustment of the air outlet plate 3-4, avoiding cold air leakage and affecting the cooling effect. The air inlet pipe 4-1 of the circulating air supply component 4 is located on the upper surface of the air hood 1. The end of the air inlet pipe 4-1 is provided with a connecting groove 4-2. There are two air inlet pipes 4-1, located on opposite sides of the upper surface of the air hood 1. This layout allows the cold air to enter the air hood 1 more evenly, and then be distributed to various parts of the computer room through the air outlet tilting component 3. The connecting groove 4-2 is used to connect to the external cold air source pipe to introduce cold air. Its interface specifications and dimensions are customized according to the external pipe standard to ensure the tightness and sealing of the connection and prevent cold air leakage. The air inlet pipe 4-1 is connected to the cooling system pipe of the computer room through the connecting groove 4-2. The cold air generated by the cooling system is transported to the air inlet pipe 4-1 through the pipe, then enters the air hood 1, and then flows to the area in the computer room that needs cooling through the air outlet tilting component 3, forming a complete cold air circulation supply path. During the connection process, the connection of the pipe must be strictly sealed and pressure tested to ensure the normal operation of the entire circulating air supply system.

[0024] When the computer room requires cooling, the cooling system starts, and cold air enters the air hood 1 through the connecting slot 4-2 on the air inlet pipe 4-1. At this time, the drive plate 3-5 starts to rotate under the drive of the motor (not mentioned, assuming a drive motor exists). The rotation of the drive plate 3-5 is transmitted to the air outlet plate 3-4 through the connecting rod 3-6. The connecting rod 3-6 pulls the air outlet plate 3-4 to rotate around the positioning shaft 3-2, causing the air outlet 3-1 to open. Cold air is blown out from the air outlet 3-1 into the computer room to dissipate heat from the equipment inside. By controlling the rotation angle and speed of the drive plate 3-5, the tilting of the air outlet plate 3-4 can be precisely adjusted. The rotation angle and opening size of the air outlet 3-1 control the air volume and direction of the cold air to meet the cooling needs of different areas and equipment in the computer room. When cooling is not needed or the circulation path of the cold air needs to be adjusted, the drive plate 3-5 rotates in the opposite direction, which drives the air outlet plate 3-4 to rotate in the opposite direction through the linkage rod 3-6, closing the air outlet 3-1 and stopping the output of cold air. At the same time, the operation of the entire system can be linked with the environmental monitoring system of the computer room, automatically adjusting the working status of the air outlet flip component 3 and the circulating air supply component 4 according to the temperature, humidity and other parameters in the computer room, so as to realize intelligent computer room cooling management.

[0025] like Figures 1-3 As shown in the figure, this embodiment proposes that the interior of the air hood 1 is provided with a drive disk 3-5, and the side wall of the drive disk 3-5 is connected to a connecting rod 3-6 by a pin. The end of the connecting rod 3-6 is connected to the air outlet plate 3-4 by a pin.

[0026] In some examples, a drive disc 3-5 is installed inside the duct 1. The drive disc 3-5 is the core drive component that controls the rotation of the air outlet plate 3-4. It is driven by a motor, and the end of the linkage rod 3-6 is also connected to the air outlet plate 3-4 through a pin.

[0027] For example, such as Figure 1 As shown, the hood 1 has a U-shaped structure. The air inlet pipes 4-1 are set on opposite sides of the upper end face of the hood 1. There are two air inlet pipes 4-1, and each air inlet pipe 4-1 has a connecting groove 4-2.

[0028] In some examples, the duct 1 is a key structural component of the entire system, and it adopts a U-shaped structure. This shape design helps to guide the direction of airflow, making it circulate more efficiently within the computer room.

[0029] For example, such as Figure 3 As shown, there are through tubes 5 at opposite ends of the linkage 3-6, and through shafts 6 are installed inside the through tubes 5. The through shafts 6 are connected to the drive disc 3-5 by pins.

[0030] In some examples, the sidewall of the drive disc 3-5 is connected to the linkage 3-6 by a pin. The two ends of the linkage 3-6 have through tubes 5, and through tubes 5 are installed inside the through tubes 5. The through tubes 6 are connected to the drive disc 3-5 by a pin. This connection method ensures that the linkage 3-6 and the drive disc 3-5 can transmit power stably.

[0031] For example, such as Figure 2 As shown, the side wall of the air outlet plate 3-4 is provided with a mounting frame 7, and the mounting frame 7 is connected to the through shaft 6 by a pin.

[0032] In some examples, the side wall of the air outlet plate 3-4 is provided with a mounting bracket 7, which is connected to the through shaft 6 by a pin. When the drive disc 3-5 rotates, the air outlet plate 3-4 is driven to rotate around the positioning shaft 3-2 through the linkage rod 3-6, thereby realizing the opening and closing of the air outlet 3-1 and the adjustment of the air outlet angle.

[0033] For example, such as Figure 2 As shown, a limiting disc 8 is provided on the side wall of the positioning shaft 3-2, and the limiting disc 8 is in contact with the connecting sleeve 3-3.

[0034] In some examples, a limiting plate 8 is provided on the side wall of the positioning shaft 3-2. The limiting plate 8 contacts the connecting sleeve 3-3. The main function of the limiting plate 8 is to limit the axial movement range of the connecting sleeve 3-3 on the positioning shaft 3-2, ensure the stability and accuracy of the air outlet plate 3-4 during the flipping process, and prevent the air outlet plate 3-4 from flipping abnormally due to excessive movement of the connecting sleeve 3-3.

[0035] For example, such as Figure 2 As shown, the air outlet plate 3-4 has an arc-shaped structure, and the outer contour of the air outlet plate 3-4 matches the outer contour of the air hood 1.

[0036] In some examples, the air outlet 3-4 is designed as an arc-shaped structure, with its outer contour matching the outer contour of the hood 1. This design not only ensures the harmony of appearance, but more importantly, it can better match the structure of the hood 1 when the air outlet 3-4 is flipped, reducing airflow resistance.

[0037] When in use, the core working principle of this computer room cold air duct electric tilting skylight is to introduce cold air through the circulating air supply component 4, and then use the electric adjustment of the air outlet tilting component 3 to achieve precise distribution and efficient circulation of cold air in the computer room. At the same time, the structural design ensures the stability and sealing of the operation. From the perspective of cold air introduction and delivery, the circulating air supply component 4 plays a key role. The cold air generated by the external refrigeration system enters the air inlet pipe 4-1 through the connecting groove 4-2 at the end of the air inlet pipe 4-1. Since the two air inlet pipes 4-1 are respectively set on opposite sides of the upper surface of the U-shaped air hood 1, the cold air can flow into the air hood 1 more evenly, laying the foundation for subsequent cold air distribution. The air outlet flip assembly 3 is responsible for regulating the output of cold air. The drive disk 3-5 is the core of the power source. When it rotates under the drive of the motor, the connecting rod 3-6 connected by the pin will move accordingly. The through shaft 6 at both ends of the connecting rod 3-6 forms a linkage structure with the drive disk 3-5 and the mounting frame 7 of the air outlet plate 3-4. When the connecting rod 3-6 is driven by the drive disk 3-5, it will pull the air outlet plate 3-4 to rotate around the positioning shaft 3-2. At this time, the air outlet plate 3-4, which was originally sealed and attached to the air outlet 3-1, flips, the air outlet 3-1 is opened, and the cold air in the air hood 1 is delivered to the machine room through the air outlet 3-1.

[0038] During the adjustment process, the limit plate 8 restricts the axial movement of the connecting sleeve 3-3 to ensure the stability of the air outlet plate 3-4 when it is flipped, and avoids sealing failure or abnormal airflow due to displacement. By controlling the rotation angle of the drive plate 3-5, the flipping range of the air outlet plate 3-4 can be precisely adjusted, thereby changing the opening size and air outlet angle of the air outlet 3-1, so as to achieve precise control of the cold air volume and air supply direction to adapt to the heat dissipation needs of different areas of the computer room.

[0039] When the computer room does not require cooling or the cold air circulation path needs to be adjusted, the drive plate 3-5 rotates in the reverse direction, and the linkage rod 3-6 pushes the air outlet plate 3-4 to reset, so that it re-seals and fits against the air outlet 3-1, closing the air outlet 3-1, blocking the cold air output, and reducing energy waste. In addition, the system can be linked with the computer room environment monitoring system to automatically control the operating status of the drive plate 3-5 and the circulating air supply component 4 based on real-time monitored parameters such as temperature and humidity, so as to realize intelligent cold air supply management and ensure that the computer room equipment operates efficiently in a suitable temperature environment.
