Description
Technical Field
[0001] This utility model relates to the field of computer room ventilation technology, and in particular to an airflow optimization guide plate for enclosed computer room passages. Background Technology
[0002] Airflow optimization deflectors in enclosed computer room aisles are key components used to optimize airflow organization within these aisles. They are typically installed under the raised floor, at the cold aisle entrance, or inside server racks. Through proper design of their shape, angle, and installation location, they can effectively guide cold air precisely to heat-generating equipment, reducing airflow short-circuiting and turbulence. Deflectors significantly improve the uniformity of airflow distribution in the computer room, reduce the probability of localized hotspots, increase cooling efficiency, and contribute to the stable and energy-efficient operation of the computer room.
[0003] However, the fixed installation angle of the airflow optimization guide plate in the closed passage of the computer room makes it difficult for the guide plate to adapt to the new airflow organization requirements when the equipment layout is adjusted or new equipment is added, which may result in insufficient or excessive cold air distribution in some areas, forming new hot spots or wasting energy. This reduces the adaptability of the guide plate to different operating conditions and the flexibility of airflow optimization, making it difficult to continuously match the dynamic heat dissipation requirements of the computer room to maintain the best cooling effect. Utility Model Content
[0004] The purpose of this invention is to solve the problem that in the existing technology, the airflow optimization guide plate for the closed passage of the computer room has a fixed installation angle. When the equipment layout is adjusted or new equipment is added, which leads to changes in heat dissipation requirements, the guide plate with a fixed angle is difficult to adapt to the new airflow organization requirements. This can easily cause insufficient or excessive cold air distribution in some areas, forming new hot spots or wasting energy. This reduces the adaptability of the guide plate to different operating conditions and the flexibility of airflow optimization, and makes it difficult to continuously match the dynamic heat dissipation requirements of the computer room to maintain the best cooling effect. Therefore, this invention proposes an airflow optimization guide plate for the closed passage of the computer room.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: an airflow optimization guide plate for a closed passageway in a computer room, comprising a ventilation duct, an air inlet, and a flow-blocking device. The air inlet is located at one end of the ventilation duct. The flow-blocking device includes a baffle plate, which is rotatably connected to the ventilation duct. A traction rope is fixedly connected to one end of the baffle plate, and the end of the traction rope away from the baffle plate passes through the ventilation duct. A bracket is fixedly connected to the lower surface of the ventilation duct, and a rotating rod is rotatably connected to the surface of the bracket. The end of the traction rope away from the baffle plate is fixedly connected to the rotating rod. Wheels are rotatably connected to both ends of the ventilation duct, and the wheels contact the traction rope. A motor is fixedly connected to the lower surface of the ventilation duct. By setting the flow-blocking device, the motor can drive the auxiliary gear and the main gear to drive the rotating rod to wind or release the traction rope, thereby rotating the baffle plate to flexibly adjust the flow-guiding angle and adapt to the airflow guidance requirements under different working conditions. Furthermore, a return spring can reset the baffle plate when the motor rotates in the opposite direction.
[0006] Preferably, the drive end of the motor is fixedly connected to a secondary gear, and the surface of the rotating rod is fixedly connected to a primary gear. The primary gear and the secondary gear are meshed together. By setting the motor, the secondary gear is driven to rotate, which in turn drives the primary gear to rotate, thereby causing the rotating rod to rotate. This enables the traction rope to be wound up or unwound, thereby driving the baffle to rotate or causing it to move in the opposite direction under the action of the return spring, thereby adjusting the angle of the guide plate and controlling the opening and closing of the ventilation duct and the guide angle.
[0007] Preferably, there are two baffles arranged symmetrically. By setting the baffles, they can rotate to change the guiding angle, thereby adjusting the direction and distribution of airflow, so as to guide and regulate the airflow in the ventilation duct. At the same time, when they are used in conjunction with the column, they can completely close the ventilation duct and play the role of sealing the duct.
[0008] Preferably, a return spring is fixedly connected to one end of the baffle, and the end of the return spring away from the baffle is fixedly connected to the ventilation duct. By setting the return spring, the angle of the guide plate can be flexibly adjusted to meet the airflow guidance requirements under different working conditions and improve the adaptability and flexibility of airflow optimization.
[0009] Preferably, a limiting component is provided at one end of the ventilation duct. The limiting component includes a bending rod, which is fixedly connected to the ventilation duct. A column is slidably connected to the surface of the bending rod. A sliding hole is formed on the surface of the bending rod, and a retaining ring is fitted onto the surface of the bending rod. The retaining ring is slidably connected to the sliding hole. By setting the limiting component, when the baffle completely closes the ventilation duct, it is pressed against the column. The column retracts the bending rod to reduce over-rotation and facilitate the duct closure. When the baffle unfolds, the pressure spring causes the column to extend again, ensuring accurate positioning of the baffle.
[0010] Preferably, the column is fixedly connected to the retaining ring, and the bending rod is set in an "L" shape. By setting the column, the column is pressed and cooperated with the baffle during the rotation of the baffle. The column restricts the rotation position of the baffle through its own extension and contraction, preventing the baffle from rotating excessively. This ensures that the baffle can accurately seal the ventilation duct when closed and provides stable limiting support for the baffle when unfolded, ensuring the accuracy of the working position of the baffle.
[0011] Preferably, a pressure spring is fitted onto the surface of the bent rod, and the two ends of the pressure spring are fixedly connected to the bent rod and the retaining ring, respectively.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] In this invention, by setting up a flow-blocking device, when the angle of the guide plate needs to be adjusted, the motor is started. The motor drives the secondary gear to rotate, which in turn drives the main gear to rotate. The rotation of the main gear drives the rotating rod to rotate, and the rotation of the rotating rod simultaneously drives the traction rope to wind up. The winding of the traction rope causes the baffle to rotate, and the angle of the guide plate changes as the baffle rotates. Once the appropriate position is reached, the motor can be turned off. When the motor rotates in the opposite direction, the rotating rod releases the traction rope, the baffle is unrestrained, and the return spring generates elastic force to squeeze the baffle to move in the opposite direction. By setting up the flow-blocking device, the motor can drive the secondary gear and the main gear to drive the rotating rod to wind up or release the traction rope, thereby realizing the rotation of the baffle to flexibly adjust the guide angle and adapt to the airflow guidance requirements under different working conditions. Moreover, the return spring can reset the baffle when the motor rotates in the opposite direction.
[0014] In this invention, by setting a limiting component, when the baffle completely closes the ventilation duct, it presses against the column, causing the column to retract into the bent rod under force, reducing the possibility of the baffle rotating too far and facilitating the closure of the ventilation duct. When the baffle unfolds, the pressure spring generates elastic force to press the column to extend again. By setting a limiting component, when the baffle completely closes the ventilation duct, it presses against the column, causing the column to retract into the bent rod, reducing the possibility of excessive rotation and facilitating the closure of the duct. When the baffle unfolds, the pressure spring causes the column to extend again, ensuring accurate positioning of the baffle. Attached Figure Description

[0021] Please see Figures 1-5 This utility model provides a technical solution: an airflow optimization guide plate for a closed passage in a computer room, including a ventilation duct 1, an air inlet 2 and a baffle device 3, wherein the air inlet 2 is located at one end of the ventilation duct 1.
[0022] In this embodiment: the flow-blocking device 3 includes a baffle 31, which is rotatably connected to the ventilation duct 1. One end of the baffle 31 is fixedly connected to a traction rope 34, and the end of the traction rope 34 away from the baffle 31 passes through the ventilation duct 1. A bracket 35 is fixedly connected to the lower surface of the ventilation duct 1, and a rotating rod 32 is rotatably connected to the surface of the bracket 35. The end of the traction rope 34 away from the baffle 31 is fixedly connected to the rotating rod 32. Both ends of the ventilation duct 1 are rotatably connected to wheels 36, which contact the traction rope 34. A motor 37 is fixedly connected to the lower surface of the ventilation duct 1. By setting the flow-blocking device 3, the motor 37 can drive the secondary gear 38 and the main gear 33 to drive the rotating rod 32 to wind up or release the traction rope 34, thereby enabling the baffle 31 to rotate to flexibly adjust the guiding angle and adapt to the airflow guidance requirements under different working conditions. The reset spring 310 can reset the baffle 31 when the motor 37 rotates in the opposite direction.
[0023] Specifically, a secondary gear 38 is fixedly connected to the drive end of the motor 37, and a main gear 33 is fixedly connected to the surface of the rotating rod 32. The main gear 33 and the secondary gear 38 are meshed together. By setting the motor 37, the secondary gear 38 is driven to rotate, which in turn drives the main gear 33 to rotate, thereby causing the rotating rod 32 to rotate, realizing the winding or unwinding of the traction rope 34. This drives the baffle 31 to rotate or to move in the opposite direction under the action of the return spring 310, thereby adjusting the angle of the guide plate and controlling the opening and closing of the ventilation duct 1 and the guide angle.
[0024] Specifically, there are two baffles 31, which are symmetrically arranged. By setting the baffles 31, they can rotate to change the airflow angle, thereby adjusting the direction and distribution of airflow, so as to guide and regulate the airflow in the ventilation duct 1. At the same time, when they are used in conjunction with the column 392, they can completely close the ventilation duct 1, thus playing the role of sealing the duct.
[0025] Specifically, a return spring 310 is fixedly connected to one end of the baffle 31, and the end of the return spring 310 away from the baffle 31 is fixedly connected to the ventilation duct 1. By setting the return spring 310, the angle of the guide plate can be flexibly adjusted to meet the airflow guidance requirements under different working conditions and improve the adaptability and flexibility of airflow optimization.
[0026] Specifically, a limiting component 39 is provided at one end of the ventilation duct 1. The limiting component 39 includes a bending rod 391, which is fixedly connected to the ventilation duct 1. A column 392 is slidably connected to the surface of the bending rod 391. A sliding hole is opened on the surface of the bending rod 391, and a retaining ring 393 is fitted on the surface of the bending rod 391. The retaining ring 393 is slidably connected to the sliding hole.
[0027] In this embodiment: by setting a limiting component 39, when the baffle 31 completely closes the ventilation duct 1, it is pressed against the column 392, and the column 392 retracts the bending rod 391 to reduce over-rotation and facilitate the closure of the duct. When the baffle 31 unfolds, the pressure spring 394 causes the column 392 to extend again, ensuring that the baffle 31 is accurately positioned.
[0028] Specifically, the column 392 is fixedly connected to the retaining ring 393, and the bent rod 391 is set in an "L" shape.
[0029] In this embodiment: by setting up the column 392, the column 392 is pressed and cooperated with the baffle 31 during the rotation process. The column 392 restricts the rotation position of the baffle 31 through its own extension and retraction, preventing the baffle 31 from rotating excessively. This ensures that the baffle 31 can accurately seal the ventilation duct 1 when closed, and provides stable limiting support for the baffle 31 when unfolded, ensuring the accuracy of the working position of the baffle 31.
[0030] Specifically, a pressure spring 394 is fitted onto the surface of the bending rod 391, and the two ends of the pressure spring 394 are fixedly connected to the bending rod 391 and the retaining ring 393, respectively.
[0031] Working principle: By setting up the flow-blocking device 3, when the angle of the guide plate needs to be adjusted, the motor 37 is started. The motor 37 drives the secondary gear 38 to rotate, the secondary gear 38 drives the main gear 33 to rotate, the main gear 33 drives the rotating rod 32 to rotate, and the rotating rod 32 drives the traction rope 34 to wind up at the same time. The winding of the traction rope 34 drives the baffle 31 to rotate. When the baffle 31 rotates, the angle of the guide plate changes. When the appropriate position is reached, the motor 37 can be turned off. When the motor 37 rotates in the opposite direction, the rotating rod 32 releases the traction rope 34, the baffle 31 is unrestrained, and the return spring 310 generates elastic force to squeeze the baffle 31 to move in the opposite direction. By setting up the flow-blocking device 3, the motor 37 drives the secondary gear 38 and the main gear 33 to drive the rotating rod 32 to wind up or release the traction rope 34, so as to realize the rotation of the baffle 31 to flexibly adjust the guide angle, adapt to the airflow guidance requirements under different working conditions, and the return spring 310 can reset the baffle 31 when the motor 37 rotates in the opposite direction.
[0032] By setting the limiting component 39, when the baffle 31 completely closes the ventilation duct 1, it is pressed against the column 392. The column 392 is forced to retract into the bending rod 391, reducing the possibility of the baffle 31 rotating too far and facilitating the closure of the ventilation duct 1. When the baffle 31 unfolds, the pressure spring 394 generates elastic force to press the column 392 to extend again. By setting the limiting component 39, when the baffle 31 completely closes the ventilation duct 1, it is pressed against the column 392. The column 392 retracts into the bending rod 391, reducing the possibility of over-rotation and facilitating the closure of the duct. When the baffle 31 unfolds, the pressure spring 394 causes the column 392 to extend again, ensuring that the baffle 31 is accurately positioned.
