Description

Technical Field

[0001] This utility model relates to the field of electrical facility technology, specifically an outdoor cabinet for airflow heat dissipation. Background Technology

[0002] Outdoor server racks are cabinets made of metal or non-metal materials that are directly exposed to natural climate conditions. Unauthorized personnel are not permitted to enter or operate the equipment. These racks provide an outdoor physical working environment and security system for wireless communication or wired network workstations. Suitable for outdoor environments such as roadsides, parks, rooftops, mountainous areas, and flat ground, these racks can accommodate base station equipment, power supply equipment, batteries, temperature control equipment, transmission equipment, and other supporting equipment, or provide installation space and heat exchange capacity for these devices. They provide reliable mechanical and environmental protection for the normal operation of the internal equipment.

[0003] A search revealed an outdoor server rack with airflow cooling disclosed in application number 202320974251.4. This rack includes a cabinet body and doors fitted onto the cabinet body. The cabinet body includes side panels, a bottom frame at the bottom of the side panels, and a top frame at the top of the side panels. The side panels are characterized by a double-layer structure, comprising an inner layer and an outer layer, with an airflow channel between them. The top and bottom frames are open, allowing airflow exchange with the outside environment. The bottom frame has airflow holes communicating with the airflow channel of the side panels, and the top frame has an airflow cavity communicating with the airflow channel of the side panels. Stable heat dissipation of the rack is achieved through the airflow communication between the top frame, bottom frame, and side panels. This application achieves airflow flow by configuring the airflow communication between the top frame, bottom frame, and side panels, as well as airflow exchange with the outside environment. This airflow removes heat from multiple surfaces and the interior of the rack, achieving rapid heat dissipation. It is scientifically sound, structurally simple, and easy to use.

[0004] However, the above method still has the following drawbacks in actual use: it achieves airflow by setting up airflow communication between the top frame, bottom frame, and side panels and airflow exchange with the outside, but the top frame and bottom frame are both open, and rainwater and dust can easily enter the inside of the cabinet and damage the components. In addition, relying solely on natural wind power to achieve airflow has limited heat dissipation effect and makes it difficult to quickly dissipate the heat accumulated inside the cabinet.

[0026] The present invention will be further described below with reference to the accompanying drawings of the embodiments thereof.

[0027] Please see Figures 1-8In this embodiment of the utility model, an outdoor airflow cooling cabinet includes a cabinet body 1. Support bases 101 are fixedly provided on both sides of the bottom of the cabinet body 1, preventing the bottom of the cabinet body 1 from contacting the ground and preventing rainwater erosion. A rust-proof layer is coated on the surface of the support bases 101 to prevent rainwater corrosion and improve their service life. A cabinet door is hinged to the front of the cabinet body 1, and a transparent observation window made of explosion-proof glass is provided in the middle of the door. This window is not easily damaged when the internal temperature of the cabinet body 1 rises, allowing real-time observation of the internal conditions of the cabinet body 1. The cabinet body 1 also has partitions on both sides inside. The partition 2 forms an airflow cooling chamber between the partition 2 and the side wall of the cabinet body 1. The surface of the partition 2 is provided with ventilation slots 201, allowing heat inside the cabinet body 1 to be exhausted to the outside through the ventilation slots 201 on one side of the partition 2, while allowing cool air from the other side to enter the cabinet body 1 through the ventilation slots 201 on the other side of the partition 2. This achieves air circulation and heat exchange, preventing heat accumulation inside the cabinet body 1. The airflow cooling chamber is equipped with multiple rotating fan blades 206. When the fan blades 206 on both sides rotate, air convection quickly dissipates the heat inside the cabinet body 1. To dissipate heat, multiple ventilation pipes 205 are fixed on both sides of the cabinet body 1, with the external portions of the ventilation pipes 205 angled downwards. This prevents dust and rainwater from entering the cabinet body 1 through the ventilation pipes 205, thus preventing damage to internal components and improving protection. A protective box 3 is located at the top of the cabinet body 1. Inside the protective box 3 is a drive motor 304 that drives multiple ventilation fan blades 206 to rotate simultaneously. The drive shaft of the drive motor 304 synchronously rotates the multiple ventilation fan blades 206, quickly dissipating heat from inside the cabinet body 1, improving heat dissipation efficiency, and also protecting the motor. Moving the motor to the outside of the cabinet body 1 prevents the heat generated by the motor from entering the interior of the cabinet body 1. Furthermore, the rotation of multiple ventilation fan blades 206 is driven by a single motor, reducing energy consumption. The cabinet body 1 is equipped with a temperature controller (not shown in the figure, and the temperature controller is existing technology, and its model is not publicly available; a suitable model can be selected according to actual needs). The detection end of the temperature controller is located on the inner wall of the cabinet body 1, and the drive motor 304 is electrically connected to the temperature controller. The temperature controller automatically controls the drive motor 304 and monitors the temperature inside the cabinet body 1 in real time, achieving intelligent control.

[0028] In this embodiment, preferably, the partition plate 2 has folded edges on all sides, and the folded edges are connected to the inner wall of the cabinet body 1 by fixing screws, which facilitates the disassembly and assembly of the partition plate 2. A dustproof plate 203 is snapped onto the side of the partition plate 2 near the ventilation pipe 205 to block the dust entering through the ventilation pipe 205 and prevent it from entering the interior of the cabinet body 1 and causing damage to the components.

[0029] In this embodiment, preferably, the inner side of the partition plate 2 is fixedly provided with a slot 202, and the side of the dustproof plate 203 is fixedly provided with a locking edge 204 that engages with the slot 202. The position of the dustproof plate 203 is limited by the cooperation between the locking edge 204 and the slot 202, and the dustproof plate 203 can be quickly removed for cleaning when the partition plate 2 is disassembled.

[0030] In this embodiment, preferably, a mounting shaft 207 is fixedly provided in the middle of the ventilation fan blade 206. The mounting shaft 207 is rotatably connected to the inner wall of the cabinet body 1 through a bearing. A driven bevel gear 208 is fixedly provided at the end of the mounting shaft 207. Mounting shafts 209 are rotatably provided on both sides inside the cabinet body 1. A driving bevel gear 2010 is fixedly provided on the surface of the mounting shaft 209 and meshes with the driven bevel gear 208. When the mounting shaft 209 rotates, it drives the driving bevel gear 2010 to rotate. Thus, under the meshing action of the driving bevel gear 2010 and the driven bevel gear 208, the mounting shaft 207 rotates, thereby driving the ventilation fan blade 206 to rotate rapidly, which plays a role in ventilation and heat dissipation.

[0031] In this embodiment, preferably, the top of the second mounting shaft 209 penetrates the top wall of the cabinet body 1, and a sealed bearing is installed at the connection between the two. A driven gear 2011 is fixedly provided at the top of the second mounting shaft 209, and a motor frame 303 is fixedly provided on the inner wall of the top of the protective box 3. The drive motor 304 is fixedly provided at the bottom of the motor frame 303. The drive shaft of the drive motor 304 is fixedly provided with a drive gear 305 that meshes with the driven gear 2011. When the drive motor 304 is working, it drives the drive gear 305 to rotate. Under the meshing cooperation of the drive gear 305 and the driven gear 2011, the two second mounting shafts 209 rotate synchronously.

[0032] In this embodiment, preferably, the top of the protective box 3 is provided with a heat dissipation groove 306 to ventilate and dissipate the heat generated when the drive motor 304 is working. The heat dissipation groove 306 is placed on the top and can be protected by the rainproof top 4. Compared with the side, rainwater and dust are not easy to enter under the action of the rainproof top 4. The surface of the heat dissipation groove 306 is provided with a dustproof plate 307 to block dust in the air and prevent dust from entering the interior of the protective box 3. The dustproof plate 307 is connected to the top of the protective box 3 by fixing screws, which facilitates the installation and removal of the dustproof plate 307.

[0033] In this embodiment, preferably, mounting plates 102 are fixedly provided on the top of both sides of the cabinet body 1, and mounting plates 301 are fixedly provided on the bottom of both sides of the protective box 3. Mounting bolts 302 are installed between mounting plates 301 and mounting plates 102, so that the protective box 3 can be disassembled, thereby periodically inspecting the drive motor 304 inside the protective box 3. Fixing holes that cooperate with mounting bolts 302 are provided on the surfaces of mounting plates 301 and mounting plates 102.

[0034] In this embodiment, preferably, a rainproof top 4 is provided on the top of the cabinet body 1, and a mounting post 401 is fixedly provided at the bottom of the rainproof top 4. A mounting plate 402 is fixedly provided at the bottom of the mounting post 401. The mounting plate 402 is connected to the top of the protective box 3 by mounting screws. The rainproof top 4 can protect the heat dissipation groove 306 on the top of the protective box 3 and prevent rainwater from entering the interior of the protective box 3.

[0035] In use, first install the dustproof plate 203 into the interior of the partition plate 2. Use the interlocking action between the edge 204 and the slot 202 to limit the position of the dustproof plate 203. Then install the partition plate 2 with the dustproof plate 203 installed into the interior of the cabinet body 1. Use the mounting screws to connect the folded edge of the partition plate 2 to the inner wall of the cabinet body 1, thereby limiting the position of the partition plate 2. Use the partition plates 2 on both sides to protect the ventilation fan blades 206 on both sides inside the cabinet body 1.

[0036] When the rack body 1 is in use, the heat generated by the internal components accumulates inside the rack body 1. A temperature controller inside the rack body 1 monitors the internal temperature in real time. When the internal temperature of the rack body 1 exceeds the set value of the temperature controller, the temperature controller automatically controls the drive motor 304 to operate. The drive motor 304 drives the drive gear 305 to rotate. Under the meshing engagement of the drive gear 305 and the driven gear 2011, the two mounting shafts 209 rotate synchronously. The rotation of the mounting shafts 209 drives the drive bevel gear 2010 to rotate, thus causing the drive bevel gear 2010 and the driven bevel gear 2010 to rotate. The meshing action of gear 208 drives the mounting shaft 207 to rotate, which in turn drives the ventilation fan blades 206 on both sides to rotate rapidly. The ventilation fan blades 206 on both sides exhaust in the same direction. The ventilation fan blade 206 on one side draws cold outside air into the airflow cooling chamber on one side through the ventilation pipe 205 on one side, and discharges it into the interior of the cabinet body 1 through the ventilation slot 201 of the corresponding partition plate 2. Under the action of the ventilation fan blade 206 on the other side, the heat inside the cabinet body 1 is drawn into the airflow cooling chamber on the other side, and then quickly discharged through the ventilation pipe 205 on the other side, realizing convection, accelerating the airflow, and quickly dissipating the heat inside the cabinet body 1.

[0037] It is particularly important to note that the external portion of the ventilation duct 205 is angled downwards to prevent dust and rainwater from entering the cabinet body 1, thus preventing damage to internal components and improving protection. The heat generated by the drive motor 304 is quickly dissipated through the heat dissipation duct 306. The heat dissipation duct 306 is positioned on the top and protected by the rainproof top 4. Compared to a side-mounted duct, the rainproof top 4 makes it less likely for rainwater and dust to enter. The surface of the heat dissipation duct 306 is equipped with a second dustproof plate 307 to block dust in the air and prevent it from entering the protective box 3. The second dustproof plate 307 is connected to the top of the protective box 3 by fixing screws, facilitating its removal and regular cleaning.

[0038] 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.
