[0002] With the rapid development of information processing and other technologies, the functions and performance of electronic equipment are constantly improving, and the heat consumption of electronic equipment is also increasing. As the most commonly used physical carrier unit of electronic equipment, cabinets have higher requirements for their heat dissipation capabilities. On the other hand, air cooling has become the most widely used heat dissipation method for electronic equipment cabinets due to its convenience and economy. High heat dissipation capacity often brings high noise from the cooling fan, affecting the user experience of the debugging operator.

[0003] In view of the high heat dissipation requirements and high fan noise of electronic equipment, traditional electronic equipment cabinets have the following problems: 1. Traditional electronic equipment cabinets mainly have two structural forms. One is the front and rear mesh door cabinet. The cabinet body is not equipped with a fan and only relies on the equipment's own fan for heat dissipation. It is not suitable for equipment with left and right heat dissipation directions and has limited use conditions. The other is the front and rear steel plate door / glass door cabinet. The cabinet has bottom air intake and top air outlet. The top of the cabinet is usually equipped with 4 to 6 axial flow fans for exhaust. The heat dissipation capacity is within 2kW, which cannot meet the high heat dissipation requirements of electronic equipment at this stage. 2. Traditional electronic equipment cabinets usually use porous sound-absorbing materials to stick on the inner wall of the cabinet to reduce noise. This has a certain effect on medium and high frequency noise, but is limited by the material properties and cannot solve the medium and low frequency noise problem. In addition, noise leakage from the single-layer steel plate / glass at the cabinet inlet and outlet and the front and rear doors also affects the overall sound insulation performance of the cabinet.

The linkage door lock is equipped with a handle. After the lock core is rotated 180 degrees to open, the handle automatically pops up by pressing a button, and the handle is used to open and close the front door and the rear door. It should be noted that the linkage door lock can be replaced with a magnetic sealing strip and an external handle according to needs to realize the convenient opening and closing of the front door and the rear door.
