Description

Technical Field

[0001] This utility model relates to the field of AI computer cabinet technology, specifically an AI computer cabinet with adjustable heat dissipation airflow. Background Technology

[0002] With the rapid development of artificial intelligence (AI) technology, the demand for high-performance computing equipment (such as GPU servers, AI training clusters, etc.) is increasing. These devices generate a lot of heat during operation. If heat dissipation is not timely, the device temperature will be too high, which will affect computing performance, shorten hardware lifespan, and even cause failure. Therefore, the heat dissipation design of AI computer cabinets is particularly critical.

[0003] Traditional server rack cooling solutions typically employ a fixed air duct structure, relying on forced exhaust by fans or natural convection for heat dissipation. However, this design suffers from several drawbacks: cooling efficiency is not adjustable; the fixed air duct cannot dynamically adjust the heat dissipation area based on internal temperature changes, leading to excessive heat dissipation at low temperatures, wasting energy, and insufficient heat dissipation at high temperatures, impacting equipment stability. Reliance on active cooling devices necessitates the additional configuration of temperature-controlled fans or air conditioning systems in most racks, increasing energy consumption and increasing the risk of mechanical component failure due to prolonged operation. Insufficient protection is also a concern, as air inlets are usually designed to remain open, making them prone to dust accumulation or moisture buildup when not in operation, affecting heat dissipation and equipment safety. Utility Model Content

[0004] The purpose of this invention is to provide an AI computer cabinet with an adjustable heat dissipation duct, which has the effects of adaptive temperature regulation and simple and reliable structure.

[0006] A further feature of this invention is that a slide rail is fixedly provided at the bottom of the mounting frame, and a slide block that is slidably connected to the slide rail is fixedly provided at the bottom end of the transmission gear plate.

[0007] A further feature of this invention is that: a connecting seat is fixedly provided at one end of the bimetallic strip near the transmission arm, the connecting seat is rotatably connected to one end of the transmission arm, and a mounting seat is fixedly provided at the other end of the bimetallic strip away from the transmission arm, the mounting seat being fixedly connected to one side inner wall of the cabinet.

[0008] A further feature of this invention is that: one end of the transmission arm is fixedly provided with a connecting shaft one that is rotatably connected to the top of the connecting seat, and the other end of the transmission arm is fixedly provided with a connecting shaft two that is rotatably connected to the top of the transmission gear plate at a position away from the bimetallic strip.

[0009] A further feature of this invention is that the bottom of the side of the mounting frame is provided with a transmission groove corresponding to the transmission gear.

[0010] A further feature of this invention is that air inlet slots are provided on both sides of the cabinet, and air inlet covers are fixedly installed inside the air inlet slots.

[0011] A further feature of this invention is that: both sides of the cabinet are fixedly provided with limiting frames, and the inside of the limiting frames is provided with a split protective plate, and the surface of the protective plate is provided with a handle.

[0012] A further feature of this invention is that: fixed seats are fixedly provided at both ends of the limiting frame, and the fixed seats are fixedly connected to the side of the cabinet by fixing bolts.

[0014] In summary, this utility model has the following beneficial effects: The adaptive temperature regulation of this utility model uses a bimetallic strip to sense temperature changes inside the cabinet, automatically driving the transmission arm and transmission gear plate to rotate the adjustment plate, achieving stepless adjustment of the opening and closing angle of the heat dissipation duct. When the temperature rises, the duct expands to enhance heat dissipation; when the temperature drops, the duct shrinks to reduce energy consumption. No manual intervention or additional power is required, making it energy-efficient and highly effective. The structure is simple and reliable, employing a gear and tooth plate transmission and a slide rail guide mechanism to ensure smooth and highly synchronized rotation of the adjustment plate. The direct linkage design between the bimetallic strip and the mechanical transmission components eliminates complex circuits or sensors, reducing the failure rate and maintenance costs. Multiple protection functions are provided: a sliding protective plate is provided on the outside of the air inlet hood, with the opening and closing states fixed by limit screws and locking nuts. When not in operation, it can be closed to prevent dust and moisture. The protective plate adopts a split design, making disassembly and assembly convenient and facilitating cleaning or maintenance of the air inlet hood. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings of the embodiments thereof.

[0024] Please see Figures 1-7 In this embodiment of the present invention, an AI computer cabinet with adjustable heat dissipation ducts includes a cabinet body 1. A mounting frame 2 is fixedly installed on the top of the back of the cabinet body 1. Multiple heat dissipation ducts 201 are provided inside the mounting frame 2. An adjustment plate 202 is rotatably installed inside the heat dissipation ducts 201 via a rotating shaft 203. A transmission gear 204 is fixedly installed at the bottom of the rotating shaft 203. A transmission toothed plate 207 is slidably installed at the bottom of the mounting frame 2, meshing with the transmission gear 204. When the transmission toothed plate 207 moves, it can drive the transmission gear 204 to rotate, thereby driving the opening and closing angle of the adjustment plate 202 to adjust the heat dissipation area of ​​the heat dissipation ducts 201. A bimetallic strip 209 is installed inside the cabinet body 1. One end of the bimetallic strip 209 is connected to one end of the transmission toothed plate 207 via a transmission arm 2012. When heated, the bimetallic strip 209 bends towards the heat dissipation ducts 201, and under the action of the transmission arm 2012, it pulls the transmission toothed plate 207 to move.

[0025] In this embodiment, preferably, a slide rail 206 is fixedly provided at the bottom of the mounting frame 2, and a slide seat 208 that is slidably connected to the slide rail 206 is fixedly provided at the bottom end of the transmission tooth plate 207. The sliding cooperation between the slide seat 208 and the slide rail 206 guides the movement of the transmission tooth plate 207.

[0026] In this embodiment, preferably, a connecting seat 2011 is fixedly provided at one end of the bimetallic strip 209 near the transmission arm 2012, and the connecting seat 2011 is rotatably connected to one end of the transmission arm 2012. A mounting seat 2010 is fixedly provided at the other end of the bimetallic strip 209 away from the transmission arm 2012. The mounting seat 2010 is fixedly connected to one side inner wall of the cabinet 1 to fix the position of the bimetallic strip 209 and not interfere with the bending of the end of the bimetallic strip 209.

[0027] In this embodiment, preferably, one end of the transmission arm 2012 is fixedly provided with a connecting shaft 1 that is rotatably connected to the top end of the connecting seat 2011, and the other end of the transmission arm 2012 is fixedly provided with a connecting shaft 2 that is rotatably connected to the top end of the transmission gear plate 207 away from the bimetallic strip 209, thereby limiting the position of the transmission arm 2012 and causing it to drive the transmission gear plate 207 to move.

[0028] In this embodiment, preferably, the bottom of the side of the mounting frame 2 is provided with a transmission groove 205 corresponding to the transmission gear 204, which can install the transmission gear 204 without interfering with the rotation of the transmission gear 204.

[0029] In this embodiment, preferably, air inlet slots are provided on both sides of the cabinet 1, and an air inlet cover 3 is fixedly installed inside the air inlet slot to assist the outside cold air to enter the interior of the cabinet 1 and improve heat dissipation efficiency.

[0030] In this embodiment, preferably, both sides of the cabinet 1 are fixedly provided with limiting frames 301, and the inside of the limiting frame 301 is provided with a split protective plate 305. The protective plate 305 can protect the air inlet cover 3 when the cabinet 1 is not in use. The surface of the protective plate 305 is provided with a handle 306, which makes it easy to push the protective plate 305 to open and close.

[0031] In this embodiment, preferably, the two ends of the limiting frame 301 are fixedly provided with fixing seats 302, and the fixing seats 302 are fixedly connected to the side of the cabinet 1 by fixing bolts 303, which facilitates the quick disassembly of the limiting frame 301, thereby allowing the protective plate 305 to be disassembled and assembled.

[0032] In this embodiment, preferably, the surface of the limiting frame 301 is provided with a limiting groove 304, and one end of the protective plate 305 is fixedly provided with a limiting screw 307 that slides in the limiting groove 304, so as not to interfere with the opening and closing of the protective plate 305. The end of the limiting screw 307 is provided with a locking nut 308. The threaded engagement between the locking nut 308 and the limiting screw 307 can limit the opening of the protective plate 305 and prevent it from moving on its own.

[0033] In use, when the temperature inside cabinet 1 rises due to the operation of the AI ​​computing device, the bimetallic strip 209 fixed to the inner wall of cabinet 1 deforms due to heat, and its free end bends towards the heat dissipation duct 201. The bimetallic strip 209 is hinged to the transmission arm 2012 through the connecting seat 2011. During the deformation process, it pulls the transmission arm 2012 to move, which in turn drives the transmission gear plate 207, which is hinged to the other end of the transmission arm 2012, to slide horizontally along the slide rail 206. The movement of the transmission gear plate 207 drives the transmission gear 204 meshing with it to rotate. The transmission gear 204 is fixed on the rotating shaft 203, thereby driving the adjusting plate 202 to rotate within the heat dissipation duct 201. The higher the temperature, the greater the bending amplitude of the bimetallic strip 209, the greater the displacement of the transmission gear plate 207, the greater the opening angle of the adjusting plate 202, the larger the ventilation area of ​​the heat dissipation duct 201, and the faster the heat dissipation. When the temperature drops... When the temperature is low, the bimetallic strip 209 retracts, the transmission gear plate 207 moves in the opposite direction, and the adjusting plate 202 closes to reduce the area of ​​the heat dissipation duct 201 and maintain a suitable temperature inside the cabinet. The air inlet covers 3 on both sides of the cabinet 1 introduce external cold air through the air inlet slots, forming a convection heat dissipation path from bottom to top. In the non-working state, the protective plate 305 can be manually pushed to slide along the limit frame 301 to the closed position, and the limit screw 307 is fixed by the locking nut 308 to close the air inlet cover 3 and prevent dust from entering. When working, the protective plate 305 is pulled open and locked to ensure unobstructed air intake. The sliding cooperation between the slide block 208 and the slide rail 206 ensures that the transmission gear plate 207 moves without deviation. The transmission gear 204 is embedded in the transmission groove 205 of the mounting frame 2, which ensures meshing accuracy and prevents dislocation. The bimetallic strip 209 is fixed by the mounting base 2010, and only the free end participates in deformation transmission to avoid overall displacement interference.

[0034] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
