Description

Technical Field

[0001] This utility model relates to the field of hot channels, and in particular to closed hot channels with adjustable flow angles. Background Technology

[0002] Enclosed hot aisles are core components of cooling systems in data centers, high-density server rooms, and industrial equipment. Their function is to create directional airflow paths, efficiently dissipating heat generated by equipment to the external environment and preventing localized temperature rises caused by hot air recirculation. By optimizing airflow organization, hot aisles can significantly improve heat dissipation efficiency, reduce cooling energy consumption, and decrease the failure rate of equipment due to overheating. In emergency scenarios such as fires, hot aisles must also have rapid smoke extraction capabilities to ensure personnel safety and reduce the risk of equipment damage.

[0003] Existing enclosed hot aisle structures typically consist of a frame structure, fixed baffles, and end doors. Cabinet mounting positions are located on the side walls of the frame, and fixed baffles or louvered structures are installed on the top to guide hot air flow towards the return air system. The baffles are mostly made of metal or plastic and are welded or riveted to the frame at a fixed angle; some designs use manually adjustable baffles.

[0004] Fixed deflectors cannot adjust their angle according to real-time temperature distribution, which can easily create turbulence or dead air zones, exacerbating the heat dissipation pressure on the equipment. In the event of a fire, fixed deflectors cannot quickly switch to the fully open state, obstructing the smoke exhaust channel, prolonging the smoke retention time, and increasing the risk of secondary disasters. Manually adjusting the deflectors requires stopping the machine, and there is a lack of precise control basis, making it difficult to match dynamically changing heat dissipation needs, resulting in high maintenance costs. Utility Model Content

[0005] In order to overcome the shortcomings of existing technical solutions, this utility model provides a closed thermal channel with adjustable flow angle, which can effectively solve the technical problem of automatic adjustment of the flow guide plate angle.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An adjustable-angle enclosed hot passage includes a passage frame, skylight components, and passage end doors. The skylight components are installed at the upper end of the passage frame. Cabinet mounting sections are provided on the side walls of the passage frame. The middle section of the passage frame is a hot flow passage, and the passage end doors are located at both ends of the hot flow passage. The key feature is that several sets of skylight components are provided, installed side-by-side. Each skylight component is connected to a return air duct. Each skylight component includes a keel support, spoilers, and servo motors. The return air duct connects to the hot flow passage through the keel support. The spoilers consist of three or more pieces. Spoilers are arranged at equal intervals in the keel support. The spoilers are connected to the keel support through a rotating shaft. The spoilers are equipped with flip arms. The servo is installed on the side wall of the keel support. The swing arm of the servo is connected to the flip arm through a connecting rod. When the swing arm rotates, it drives the flip arm through the connecting rod, so that three or more spoilers flip around their respective rotating shafts. The flip angle of each spoiler is the same. Temperature sensors and smoke sensors corresponding to the sunroof assembly are installed in the heat flow passage. A controller is installed in the passage frame. The servo, temperature sensor and smoke sensor are electrically connected to the controller.

[0008] Furthermore, the surface of the keel support is provided with a sensor light that shines in the direction of the heat flow passage and lights up when the sensor light detects that there are workers in the heat flow passage.

[0009] Furthermore, an axial flow fan is installed in the return air duct, and the axial flow fan is electrically connected to the controller.

[0010] Furthermore, the swing arm and the flip arm are provided with a ball head at one end near the connecting rod, and the surface of the connecting rod is provided with a ball socket corresponding to the ball head.

[0011] Furthermore, sealing gaskets are provided between the return air duct, the hot air passage, and the keel support.

[0012] Furthermore, the two ends of the rotating shaft are provided with self-lubricating components, which include an oil-impregnated copper sleeve and an annular oil reservoir, and the annular oil reservoir is filled with high-temperature resistant grease.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the temperature of the entire heat flow passage is controlled by several skylight components, each skylight component controls the hot air flow in a separate area, the temperature distribution in the heat flow passage is monitored in real time by temperature sensors, the controller dynamically calculates the optimal airflow angle based on temperature gradient data, and drives the servo motor to synchronously adjust the flip angle of multiple baffles, so that the airflow path is precisely matched with the heat dissipation requirements of the equipment. The flip-adjustable baffles effectively eliminate the turbulence generated by traditional fixed baffles. Three or more baffles deflect in concert to form directional airflow, which increases the hot air return flow and avoids local temperature rise caused by hot air stagnation. When the smoke sensor detects a fire signal, the controller immediately triggers the emergency mode, and all baffles are synchronously flipped to the fully open state to form an unobstructed smoke exhaust channel. In the fully open state, the baffles are parallel to the return air duct. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] The following is combined Figures 1-5 The adjustable flow-guiding angle closed thermal channel of this utility model is described in detail below:

[0022] An adjustable-angle enclosed hot passage includes a passage frame 1, a skylight assembly, and passage end doors 2. The skylight assembly is installed at the upper end of the passage frame 1. A cabinet mounting section 3 is provided on the side wall of the passage frame 1. The middle of the passage frame 1 is a hot flow passage 4. The passage end doors 2 are located at both ends of the hot flow passage 4. Three sets of skylight assemblies are provided, installed side-by-side. The skylight assembly is connected to a return air duct 5. The skylight assembly includes a keel support 6, spoilers 7, and a servo motor 8. The return air duct 5 is connected to the hot flow passage 4 through the keel support 6. Three spoilers 7 are provided, equidistantly arranged in the keel support 6. 7 is connected to the keel support 6 via the pivot 9. The spoiler 7 is equipped with a flip arm 11. The servo motor 8 is installed on the side wall of the keel support 6. The swing arm 12 of the servo motor 8 is connected to the flip arm 11 via the connecting rod 10. When the swing arm 12 rotates, it drives the flip arm 11 through the connecting rod 10, so that three or more spoilers 7 flip around their respective pivot 9. The flip angle of each spoiler 7 is the same. The heat flow passage 4 is equipped with a temperature sensor 17 and a smoke sensor 18 corresponding to the sunroof assembly. The passage frame 1 is equipped with a controller 16. The servo motor 8, the temperature sensor 17 and the smoke sensor 18 are electrically connected to the controller 16.

[0023] The rotating shaft 9 is equipped with self-lubricating components at both ends. The self-lubricating components include an oil-impregnated copper sleeve and an annular oil reservoir. The annular oil reservoir is filled with high-temperature resistant grease to prevent the rotating shaft 9 from jamming or wearing due to high-temperature dry friction, and to ensure that the spoiler 7 can still rotate smoothly in an environment above 85°C.

[0024] The temperature of the entire heat flow passage 4 is controlled by several skylight components. Each skylight component controls the hot air flow in a separate area. Temperature sensor 17 monitors the temperature distribution in the heat flow passage 4 in real time. Controller 16 dynamically calculates the optimal airflow angle based on temperature gradient data and drives servo motor 8 to synchronously adjust the flip angle of multiple baffles 7, so that the airflow path is precisely matched with the heat dissipation requirements of the equipment. The flip-adjustable baffles 7 effectively eliminate the turbulence generated by traditional fixed baffles. The three baffles 7 deflect in tandem to form directional airflow, which increases the hot air return flow and avoids local temperature rise caused by hot air stagnation. When smoke sensor 18 detects a fire signal, controller 16 immediately triggers emergency mode. All baffles 7 are simultaneously flipped to the fully open state to form an unobstructed smoke exhaust channel. In the fully open state, the baffles 7 are parallel to the return air duct 5.

[0025] The surface of the keel support 6 is provided with a sensor light 13, which shines in the direction of the heat flow passage 4. When the sensor light 13 detects that there are staff in the heat flow passage 4, it turns on to avoid misoperation or safety hazards caused by insufficient light, and achieves the effect of turning on the light when people come and turning off the light when people leave, thereby reducing energy consumption.

[0026] An axial flow fan 15 is installed inside the return air duct 5. The axial flow fan 15 is electrically connected to the controller 16. After being linked with the controller 16, the fan speed can be adjusted in real time according to the heat load. Under extreme temperature rise scenarios, it can force the hot air to be discharged, thereby improving the heat dissipation efficiency by 15%-30%. At the same time, it balances the pressure difference between the inside and outside of the system and reduces airflow turbulence. Sealing gaskets are installed between the return air duct 5, the hot flow passage 4, and the keel support 6, which can effectively prevent the mixing of hot and cold air and the intrusion of external dust, reducing airflow path loss by 8%-12%, while reducing dust accumulation inside the equipment and extending the cleaning and maintenance cycle.

[0027] The swing arm 12 and the tilting arm 11 are provided with ball heads at the ends near the connecting rod 10, and the surface of the connecting rod 10 is provided with ball sockets corresponding to the ball heads. This allows for adaptive deflection at multiple angles, eliminating the risk of jamming in traditional articulated structures, ensuring that the spoiler 7 operates accurately during long-term high-frequency adjustment, and reducing the mechanical failure rate.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
