Description

Technical Field

[0001] The utility model relates to the technical field of communication engineering, and particularly relates to a communication cabinet. Background Art

[0002] A 5G communication cabinet refers to a cabinet made of metal or non-metal materials that is directly affected by natural climate and does not allow unauthorized operators to enter and operate. It provides an outdoor physical working environment and a safety system for wireless communication sites or wired network site workstations.

[0003] Since the equipment in the communication cabinet generates heat during long-term operation, which affects the normal operation of the equipment, it is necessary to take heat dissipation measures for the communication cabinet. Currently, detachable air filters are generally installed in the communication cabinet, but the internal structure of the communication cabinet is complex and the space is small, which brings inconvenience to the staff during disassembly. Content of the Utility Model

[0004] The purpose of the utility model is to provide a communication cabinet to solve the problem that detachable air filters are generally installed in the existing communication cabinet, but the internal structure of the communication cabinet is complex and the space is small, which brings inconvenience to the staff during disassembly.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A communication cabinet includes a cabinet body. A ventilation duct is provided on the back side inside the cabinet body. A connection frame is snap-connected to the front of the top of the ventilation duct. Motors are fixedly connected at equal intervals inside the connection frame. A fan blade is fixedly connected to the output end of the motor. An air intake grille is snap-connected to the bottom of the ventilation duct. An air filter element is filled above the air intake grille inside the ventilation duct. Line holes are provided at equal intervals at the bottom of the inner wall of the cabinet body, and a water stop ring is fixedly connected to the top of the line holes;

[0007] The air filter element includes a hollow cube. Outer dust filters are integrated on the front, back, left, and right of the hollow cube, and an inner dust filter is filled inside the hollow cube.

[0008] Preferably, limiting blocks are fixedly connected to the two side surfaces of the inner wall of the ventilation duct and above the air filter element.

[0009] Preferably, clamping blocks are fixedly connected at equal intervals to the back of the widest part of the internal channel of the air intake grille, and clamping grooves are provided at positions corresponding to the clamping blocks on the back of the cabinet body.

[0010] Preferably, the inner dust filter is designed in a corrugated shape.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the present utility model, an independent air duct is added to the back of the cabinet body, a fan with a motor directly driving the fan blades is added to the top of the air duct, and an air intake grille is snap-connected to the bottom of the air duct. The fan can suck external air from the air intake grille, and then blow it into the cabinet body after filtering dust through an air filter element, thereby realizing the heat dissipation inside the cabinet body. Moreover, the design of this independent air duct can effectively transition the internal space of the cabinet body and the external space, achieving the purpose of waterproofing and moisture-proofing. At the same time, the air filter element is externally disposed, and when the filter element needs to be replaced later, the air intake grille can be directly removed for replacement without entering the cabinet body for disassembly, thereby effectively eliminating the problem that the small internal space of the cabinet body is not conducive to filter element replacement.

[0013] 2. In the present utility model, by adding a water stop ring to the top of the wire hole, it can effectively reduce the entry of dust and rainwater into the cabinet body in harsh weather such as strong winds and heavy rains, further improving the dust-proof and waterproof effects of the communication cabinet.
