Description

Technical Field

[0001] This utility model relates to the field of outdoor cabinet technology, and more specifically, to an air passage structure for an outdoor cabinet. Background Technology

[0002] With the rapid development of information technology and intelligent devices, outdoor server racks have become an important component of various infrastructures such as communications, power, and monitoring. These racks are typically deployed outdoors to protect the electronic equipment within from environmental interference and ensure stable operation. To prevent overheating and maintain a suitable temperature, server racks require effective airflow management systems to ensure good ventilation. Simultaneously, since server racks are often outdoors, facing harsh weather conditions such as wind, rain, and dust, their airflow systems must also be dustproof and waterproof. How to ensure ventilation while preventing dust and moisture from entering the server rack is a key focus of current technological development.

[0003] Existing outdoor server racks typically rely on ventilation fans and vents for air circulation, which generally depend on direct airflow to the external environment. Using fans to extract air from the rack makes it difficult to ensure dust and water resistance during efficient ventilation, resulting in moisture or dust entering the rack and affecting the stability of the equipment inside.

[0004] Therefore, there is a need to provide an air passage structure for outdoor cabinets to solve the problem that existing outdoor cabinets cannot ensure dust and water resistance during efficient air exchange. Utility Model Content

[0005] The main objective of this invention is to provide an air passage structure for an outdoor cabinet, aiming to solve the technical problems mentioned in the background section.

[0006] The present invention adopts the following technical solution:

[0007] An air duct structure for an outdoor server rack, comprising:

[0008] The cabinet body has mounting holes on its upper surface;

[0009] A ventilation assembly is embedded in the mounting hole. The ventilation assembly includes a ventilation bracket, which is fixedly connected to the cabinet. The ventilation bracket has a ventilation hole, and a ventilation fan is provided at the bottom of the ventilation bracket corresponding to the ventilation hole. A plurality of press-fit studs are provided on the upper surface of the ventilation bracket, and a locking screw is connected to the top of each press-fit stud. A ventilation cover is fitted onto the plurality of press-fit studs. The ventilation cover is slidably connected to the press-fit nut through a sliding hole. The diameter of the sliding hole is larger than the diameter of the press-fit nut, so that the ventilation cover slides in accordance with the working state of the ventilation fan.

[0010] Furthermore, a fixing cover is provided above the ventilation component, the fixing cover covers the ventilation component, and the periphery of the fixing cover is sealed to the cabinet.

[0011] Furthermore, a canopy is provided above the fixed cover, and a receiving cavity is provided inside the canopy. The canopy is fixedly connected to the cabinet along one side of the receiving cavity.

[0012] Furthermore, a number of drainage holes are provided on the periphery of the canopy near the end of the cabinet, and the upper surface of the fixed cover is higher than the number of drainage holes in the vertical direction.

[0013] Furthermore, the ventilation holes are four symmetrically arranged fan-shaped holes, the radius of the four fan-shaped holes is smaller than the radius of the ventilation cover, and the fan-shaped holes are coaxially arranged with the ventilation cover.

[0014] Furthermore, the inner bottom wall of the cabinet is provided with several waste liquid tanks, and several hanging plates are provided above the waste liquid tanks. The hanging plates are fixedly connected to the cabinet, and gap air ducts are provided between the several hanging plates. A voltage stabilizer, an uninterruptible power supply device and an electrical cabinet are respectively provided on one side of the several hanging plates.

[0015] Furthermore, an air conditioning unit is provided on the rear end face of the cabinet. An air intake and an air outlet are provided on one side of the air conditioning unit in a vertical direction. The air outlet is located below the air intake and is positioned corresponding to the upper end face of the waste liquid tank. An air circulation port is provided in the middle of the cabinet. The air intake and the air circulation port are positioned corresponding to each other so that the cold airflow is discharged from the air outlet, passes over the waste liquid tank, flows to the air circulation port, and is then diverted from the air circulation port to the gap air duct and the air intake for circulation.

[0016] Furthermore, each of the waste liquid tanks is equipped with an exhaust pipe, and the exhaust pipes are connected in parallel to the exhaust gas pipe. The exhaust gas pipe penetrates the bottom of the cabinet through a waterproof connector, and the waterproof connector is fixedly connected to the cabinet.

[0017] Beneficial effects:

[0018] This utility model provides an airflow structure for an outdoor server rack. By creating mounting holes on the upper surface of the rack and embedding ventilation components within these holes, effective ventilation is achieved while maintaining dust and water resistance. The ventilation component includes a ventilation bracket, which is fixedly connected to the rack and has ventilation holes. Together with a ventilation fan located at the bottom, it facilitates effective airflow. When the ventilation fan is activated, it quickly expels hot air from the rack, preventing overheating and ensuring the stable operation of the electronic components inside. A locking stud on the upper surface of the ventilation bracket, in conjunction with a locking screw, provides a limiting function. The ventilation cover is slidably connected to the locking stud via a sliding hole, allowing the cover to automatically open and close according to the fan's operating status. When the fan is powered on, the airflow lifts the cover, providing effective ventilation. When the fan is powered off, the cover automatically returns to its original position due to gravity, sealing tightly and preventing dust and moisture from entering the rack, thus improving the protection and stability of the equipment inside.

[0031] Reference Figures 1 to 3 This utility model proposes an air passage structure for an outdoor cabinet, comprising:

[0032] Cabinet 1, wherein the upper end face of the cabinet 1 is provided with mounting holes;

[0033] A ventilation assembly 2 is embedded in the mounting hole. The ventilation assembly 2 includes a ventilation bracket 210, which is fixedly connected to the cabinet 1. The ventilation bracket 210 has a ventilation hole 211. A ventilation fan 220 is provided at the bottom of the ventilation bracket 210 corresponding to the ventilation hole 211. A plurality of press-fit studs 230 are provided on the upper surface of the ventilation bracket 210. A locking screw 240 is connected to the top of each press-fit stud 230. A ventilation cover 250 is fitted onto the plurality of press-fit studs 230. The ventilation cover 250 is slidably connected to the press-fit nut through a sliding hole. The diameter of the sliding hole is larger than the diameter of the press-fit nut, so that the ventilation cover 250 slides in conjunction with the working state of the ventilation fan 220.

[0034] In the above embodiment, the air passage structure of the outdoor cabinet achieves effective airflow management while maintaining dust and water resistance by opening mounting holes on the upper surface of the cabinet 1 and embedding ventilation components 2 in the mounting holes. The ventilation component 2 includes a ventilation bracket 210, which is fixedly connected to the cabinet 1 to ensure its stability. The ventilation bracket 210 has ventilation holes 211, which, together with the ventilation fan 220 at the bottom, effectively exhaust hot air from inside the cabinet, preventing overheating and ensuring the normal operation of the electronic components inside the cabinet. Several press-fit studs 230 are provided on the upper surface of the ventilation bracket 210, which, in conjunction with locking screws 240, provide a stable fixation, ensuring the stability of the ventilation component 2 during long-term operation.

[0035] The ventilation cover 250 of the ventilation assembly 2 is slidably connected to the rivet nut via a sliding hole. The diameter of the sliding hole is larger than the diameter of the rivet nut, allowing the ventilation cover 250 to automatically open and close according to the operating status of the ventilation fan 220. When the fan starts, the ventilation cover 250 is blown up by the airflow, providing sufficient ventilation and promoting air circulation inside the cabinet. When the fan is powered off, the ventilation cover 250 automatically returns to its closed state due to gravity, tightly sealing to prevent external dust and moisture from entering the cabinet. The air passage structure of the outdoor cabinet ensures ventilation while effectively preventing external environmental damage to the equipment inside the cabinet, enhancing the cabinet's dustproof and waterproof performance, and improving the protection and operational stability of the equipment inside the cabinet.

[0036] refer to Figure 2 In one embodiment, a fixing cover 3 is provided above the ventilation component 2, the fixing cover 3 covers the ventilation component 2, and the periphery of the fixing cover 3 is sealed to the cabinet 1.

[0037] In the above embodiment, a fixing cover 3 is provided above the ventilation component 2, covering the ventilation component 2, and the fixing cover 3 is sealed to the cabinet 1 on all sides. The fixing cover 3 enhances the stability of the ventilation component 2 and ensures its protective performance in harsh environments. The closed structure of the fixing cover 3 effectively isolates the external environment from interference with the ventilation structure, preventing rainwater or dust from directly entering the ventilation component 2 and extending its service life. In addition, the sealed connection of the fixing cover 3 ensures that the airflow system inside the cabinet is not affected by external pollutants, thereby improving the dust and water resistance during the ventilation process and ensuring the safe and stable operation of the equipment inside the cabinet.

[0038] refer to Figure 1 In one example, a canopy 4 is provided above the fixed cover 3, and a receiving cavity is provided inside the canopy 4. The canopy 4 is fixedly connected to the cabinet 1 along one side of the receiving cavity.

[0039] In the above embodiment, a canopy 4 is provided above the fixed cover 3, and a receiving cavity is provided inside the canopy 4. The canopy 4 is fixedly connected to the cabinet 1 along one side of the receiving cavity. The canopy 4 provides an additional protective layer for the ventilation assembly 2, and further optimizes the airflow path through the space of the receiving cavity, ensuring the ventilation effect of the ventilation assembly 2 during operation. The receiving cavity can effectively circulate air, enhance the stability and smoothness of airflow, thereby improving the air exchange efficiency inside the cabinet.

[0040] In one embodiment, a plurality of drainage holes are provided on the periphery of the canopy 4 near the end of the cabinet 1, and the upper surface of the fixed cover 3 is higher than the plurality of drainage holes in the vertical direction.

[0041] In the above embodiment, several drainage holes are provided on the periphery of the canopy 4 near the end of the cabinet 1, and the upper surface of the fixing cover 3 is higher than these drainage holes in the height direction. The drainage holes are mainly used to guide the water that may accumulate on the canopy 4 in windy and rainy weather to drain out, preventing water droplets from accumulating and entering the cabinet. The drainage holes are designed to be relatively low, and through reasonable guidance, ensure that water can drain out smoothly without affecting the normal airflow. Since the height of the fixing cover 3 is set higher than the drainage holes, water can effectively flow out from the drainage holes without causing water accumulation or backflow.

[0042] refer to Figure 3 In one embodiment, the ventilation holes 211 are four symmetrically arranged fan-shaped holes, the radius of the four fan-shaped holes is smaller than the radius of the ventilation cover 250, and the fan-shaped holes are coaxially arranged with the ventilation cover 250.

[0043] In the above embodiment, the ventilation holes 211 are four symmetrically arranged fan-shaped holes, the radius of which is smaller than the radius of the ventilation cover 250. These fan-shaped holes are coaxially arranged with the ventilation cover 250, allowing the ventilation cover 250 to completely cover the fan-shaped holes during operation. This allows the ventilation cover 250 to be blown up by the ventilation fan 220. The symmetrical arrangement of the four fan-shaped holes effectively balances the airflow direction, making the ventilation process more stable and efficient. It also prevents uneven airflow distribution and effectively improves the air quality inside the cabinet.

[0044] refer to Figure 4 In one embodiment, the inner bottom wall of the cabinet 1 is provided with a plurality of waste liquid tanks 5, and a plurality of hanging plates 6 are provided above the waste liquid tanks 5. The hanging plates 6 are fixedly connected to the cabinet 1, and gap air ducts 7 are provided between the plurality of hanging plates 6. A voltage stabilizer 8, an uninterruptible power supply device 9 and an electrical cabinet 10 are respectively provided on one side of the plurality of hanging plates 6.

[0045] In the above embodiment, several waste liquid tanks 5 are provided on the inner bottom wall of the cabinet 1, and multiple hanging plates 6 are provided above the waste liquid tanks 5. The hanging plates 6 are fixedly connected to the cabinet 1, and a certain distance is left between the hanging plates 6 to form a gap air duct 7. By setting multiple waste liquid tanks 5 and hanging plate 6 system in the cabinet 1, the internal space of the cabinet is rationally utilized to effectively treat waste liquid, while the gap air duct 7 promotes air flow and exhaust of exhaust gas. A voltage stabilizer 8, an uninterruptible power supply (UPS) device 9, and an electrical cabinet 10 are respectively set on one side of the hanging plate 6. The layout of multiple devices optimizes the use of the internal space of the cabinet, while the gap air duct 7 helps to remove the heat generated by the electronic equipment, maintain the temperature stability inside the cabinet, effectively avoid the accumulation of exhaust gas and heat, improve the working environment inside the cabinet, and extend the service life of various devices in the cabinet.

[0046] refer to Figure 5 In one embodiment, an air conditioning unit 11 is provided on the rear end face of the cabinet 1. An air intake 12 and an air outlet 13 are provided on one side of the air conditioning unit 11 in a vertical direction. The air outlet 13 is located below the air intake 12 and is located on the upper end face of the waste liquid tank 5. An air circulation port 14 is provided in the middle of the cabinet 1. The air intake 12 is corresponding to the air circulation port 14 so that the cold airflow is discharged from the air outlet 13, passes over the waste liquid tank 5 and flows to the air circulation port 14, and is diverted from the air circulation port 14 to the gap air duct 7 and the air intake 12 for circulation.

[0047] In the above embodiment, an air conditioning unit 11 is provided on the rear end face of the cabinet 1. An air intake 12 and an air outlet 13 are provided on one side of the air conditioning unit 11 in a vertical direction. The air outlet 13 is located below the air intake 12 and corresponds to the upper end face of the waste liquid tank 5. The design of the air conditioning unit 11 optimizes the flow path of the cold air. When cool air is discharged from the air outlet 13, it first flows through the waste liquid tank 5, carrying away the heat generated by the waste liquid tank 5. It then flows to the bottom of the cabinet and then upwards to the air vent 14. The air vent 14 is a cavity in the middle of the cabinet. Before the air vent 14, the airflow is divided into two parts: one part continues upwards to the mounting plate 6, voltage regulator 8, uninterruptible power supply (UPS) equipment 9, and electrical cabinet 10; the other part goes directly to the air intake 12 of the air conditioning unit 11. The airflow passing through the mounting plate 6 then returns and merges with the airflow from the air vent 14, flowing together towards the air intake 12, thus forming a circulating airflow path. This effectively removes heat from the cabinet while allowing the cool airflow to circulate continuously, maintaining a suitable temperature for the equipment throughout the cabinet. This structure helps ensure the stability of the equipment within the cabinet and prevents equipment failure due to overheating.

[0048] refer to Figure 6 In one embodiment, each of the waste liquid tanks 5 is provided with an exhaust pipe, and the exhaust pipes are connected in parallel to the exhaust pipe 15. The exhaust pipe 15 penetrates the bottom of the cabinet 1 through a waterproof connector, and the waterproof connector is fixedly connected to the cabinet 1.

[0049] In the above embodiment, each of the waste liquid tanks 5 is equipped with an exhaust pipe, and exhaust pipes 15 are connected in parallel to a single exhaust pipe 15. The exhaust pipe 15 penetrates the bottom of the cabinet 1 through a waterproof connector, which is fixedly connected to the cabinet 1. The exhaust pipe design ensures that the waste gas inside the waste liquid tanks 5 can be discharged in a timely and effective manner, preventing it from accumulating inside the cabinet and thus avoiding any impact on the equipment. The exhaust pipe 15 is fixedly connected to the cabinet 1 through the waterproof connector, effectively preventing the waste gas from being drawn back into the cabinet. At the same time, the design of the waterproof connector ensures the airtightness of the cabinet in harsh environments, preventing external moisture from penetrating into the cabinet.
