Abstract
Description
Technical Field
[0001] This utility model relates to the field of communication and power equipment protection technology, specifically to an outdoor integrated cabinet. Background Technology
[0002] With the large-scale construction of infrastructure such as rail transit, communication base stations, and smart grids, the demand for outdoor equipment cabinets is increasing. Outdoor cabinets are exposed to harsh environments such as high temperature, high humidity, dust, rain, and snow for extended periods, and must have good protective performance and heat dissipation capabilities, while also considering ease of construction and efficiency of subsequent operation and maintenance.
[0003] Traditional server rack cooling systems typically use a single air conditioner. If the air conditioner malfunctions, the temperature inside the rack will rise rapidly, potentially causing equipment downtime or damage, resulting in insufficient system reliability. Existing racks lack effective isolation and protection in the cable entry area at the bottom. Power cables, signal cables, and fiber optic cables share the same entry channel, which can easily cause electromagnetic interference. Furthermore, the large opening at the bottom allows rainwater, dust, and rodents to enter, affecting the stable operation of the system. In addition, traditional rack doors are often externally mounted to the rack body, with the doors protruding from the outer surface of the rack, resulting in weak pry resistance and insufficient physical security. Utility Model Content
[0004] The purpose of this utility model is to provide an outdoor integrated cabinet to solve the problems of poor heat dissipation and insufficient cable entry protection in existing cabinets.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: an outdoor integrated cabinet, including a first cabinet, a second cabinet, a base and a top cover arranged side by side;

The base is fixedly connected to the bottom of the main structure of the cabinet, and the top cover is embedded and connected to the top of the main structure of the cabinet.
[0007] An electric air valve is installed at the entrance of the sealed air exchange channel. The electric air valve is electrically connected to the air conditioning controller of the dual air conditioning cooling system. When any air conditioner fails, the air conditioning controller drives the electric air valve to open automatically, so as to connect the internal space of the first cabinet and the second cabinet for heat exchange.
[0008] Furthermore, the base has a cable protection compartment inside, a flange outlet on the base, and the rest of the base is sealed.
[0009] Furthermore, a drain hole is provided at the bottom of the base, and a rubber plug is installed inside the drain hole.

[0024] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0025] like Figures 1 to 3 As shown, an outdoor integrated cabinet includes a first cabinet 1, a second cabinet 2, a base 3, and a top cover 4 arranged side by side.
[0026] Both the first cabinet 1 and the second cabinet 2 are enclosed cabinets with independent doors 10, connected horizontally side-by-side by bolt pairs to form the main cabinet structure. The external dimensions (width × depth × height) of the main cabinet structure are approximately 1302mm × 800mm × 1529mm, with an effective internal installation space of no less than 30U, providing ample installation space for equipment processing units, UPS and battery packs, surge protection components, video surveillance devices, communication modules, and power access equipment. The entire unit has a waterproof and dustproof rating of no less than IP55, and a drainage hole is provided at the bottom to prevent water accumulation inside the cabinet under extreme rainfall conditions; the drainage hole is equipped with a rubber plug.
[0027] The base 3 is fixedly connected to the bottom of the main structure of the cabinet, serving as the load-bearing foundation and cable protection unit for the entire cabinet. The base 3 is made of 4mm thick steel plate, is completely enclosed, has high structural strength, and also has rodent-proof, dust-proof and bottom heat insulation functions.
[0028] The top cover 4 is embedded and connected to the top of the main structure of the cabinet. The embedded connection method effectively prevents external prying and improves the physical safety level of the whole machine.
[0029] The inner wall of the main cabinet structure is equipped with a heat insulation layer, which is made of heat insulation cotton. The heat insulation layer is attached and fixed to the inner wall of the main cabinet structure to reduce the heat conduction caused by direct sunlight and reduce the energy consumption of air conditioning. The base 3 forms a bottom heat insulation space with the main cabinet structure, further blocking the conduction of heat from the ground to the cabinet.
[0030] The first cabinet 1 and the second cabinet 2 are each equipped with an air conditioner. The two air conditioners form a dual air conditioning cooling system, which is redundant and backup for each other. Under normal working conditions, the two air conditioners work together to maintain a constant temperature inside the cabinet.
[0031] The base 3 has a sealed air exchange channel 5 inside, with both ends of the sealed air exchange channel 5 connected to the internal spaces of the first cabinet 1 and the second cabinet 2, respectively. An electric air valve is installed at the opening of the sealed air exchange channel 5, and the electric air valve is electrically connected to the air conditioning controller of the dual air conditioning cooling system. Under normal operating conditions, the sealed air exchange channel 5 is closed, and the internal spaces of the first cabinet 1 and the second cabinet 2 are independent. When any air conditioner malfunctions, the air conditioning controller detects the fault signal and outputs the signal to the drive actuator of the electric air valve, causing the electric air valve to open automatically, connecting the internal spaces of the first cabinet 1 and the second cabinet 2. The normally operating air conditioner then undertakes the heat exchange task between the two cabinets, maintaining a stable temperature inside the cabinet, thus achieving seamless redundancy switching of the cooling system without interrupting equipment operation.
[0032] The first cabinet 1 and the second cabinet 2 are also equipped with redundant ventilation ducts. The redundant ventilation ducts are independent of the sealed air exchange channel 5. The redundant ventilation ducts are equipped with self-starting cooling fans 7. When the temperature inside the cabinet exceeds the preset threshold, the cooling fans 7 will start automatically to provide auxiliary heat dissipation and further ensure the safe operation of the equipment inside the cabinet.
[0033] Both the cabinet door 10 of the first cabinet 1 and the cabinet door 10 of the second cabinet 2 are hinged to the frame of their respective cabinets, enabling a double-door operation that facilitates the installation and maintenance of equipment inside the cabinets by maintenance personnel. The cabinet door 10 is embedded inside the cabinet frame, forming a fitted structure between the cabinet door 10 and the cabinet frame, effectively preventing external prying.
[0034] The base 3 has a cable protection compartment inside, which is used to centrally protect and manage the cables entering and leaving the cabinet. The base 3 has a flange cable outlet 6. Except for the flange cable outlet 6, the rest of the base 3 is sealed, forming a fully sealed bottom structure, which effectively prevents rainwater, sand and dust and rodents and insects from entering the cabinet from the bottom.
[0035] The cable protection compartment inside base 3 has multiple independent cable inlets. Preferably, these include dedicated channels for power cables, signal cables, and optical fibers, which are independently isolated from each other to avoid electromagnetic interference between power cables and signal cables, thus improving the stability of system communication and power supply. The flange outlets 6 are equipped with bidirectional flanges, allowing for on-site adjustment of the cable outlet direction according to terrain and interface orientation requirements, enhancing installation flexibility.
[0036] The main structure of the cabinet is equipped with a door-opening sensor lighting device. This device is linked to the opening and closing of the cabinet door 10 via a sensor switch located on the door frame. The light automatically turns on when the cabinet door 10 is opened. When the cabinet door 10 is opened, the sensor switch is triggered, and the lighting device automatically turns on to provide illumination for maintenance personnel. When the cabinet door 10 is closed, the lighting device automatically turns off to save energy.
[0037] The main structure of the cabinet has internal sensor mounting positions for installing at least one of video sensors, smoke sensors, or water immersion sensors, which can be flexibly configured according to actual needs. The cabinet also has reserved installation space and wiring ports for an environmental monitoring host, supporting integration with a remote status management system to achieve real-time monitoring and remote management of environmental parameters inside the cabinet.
[0038] Before installing the server rack, the ground foundation must be constructed. The foundation should be made of C30 concrete, reinforced concrete structure, with main reinforcement diameter Φ20mm and auxiliary reinforcement diameter Φ10mm. The foundation should be at least 100mm above the ground. The foundation depth in the corresponding area at the bottom of the server rack should be at least 400mm, and the depth in other areas should be at least 200mm. The site area should be 2000mm long and 1800mm wide. L-shaped fastening bolts with a specification of M18×500mm should be pre-embedded in the foundation.
[0039] After the foundation construction is completed and reaches the design strength, align the base 3 with the ground foundation using pre-embedded L-shaped fastening bolts and tighten with nuts. The nuts should be located inside the base 3 and not exposed to the outside to prevent unauthorized disassembly or damage. After the base 3 is installed and leveled, fix the first cabinet 1 and the second cabinet 2 to the base 3 in sequence using mounting bolts. Finally, insert the top cover 4 to complete the assembly. The inner side of the cabinet should be at least 5 meters away from the center line of the wiring, and the cabinet door 10 should not open towards the wiring to ensure safe operation and maintenance.
[0040] Additionally, it should be noted that components not described in detail in this article are existing technologies.
[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
