Description

Technical Field

[0001] The utility model relates to the technical field of current-sharing grids, in particular to a current-sharing grid for communication equipment. Background Art

[0002] In the thermal design of communication equipment, for solutions involving fan blowing for cooling, the general problem is that the air volume of each single board or module is not balanced. Generally, a communication equipment includes at least one chassis, and multiple single boards or modules are configured in the chassis. A duct is formed between two adjacent single boards or modules. Thus, each chassis contains multiple ducts (usually more than a dozen). In thermal design, it is generally desired that cold air can flow evenly through each duct.

[0003] For example, the patent number CN200520121080.2 discloses a current-sharing grid for communication equipment. The current-sharing grid for communication equipment is disposed between the fan air outlet and the chassis, and includes a frame and a dust-proof net. The frame is used to fix the dust-proof net. The dust-proof net preferably has a ventilation rate greater than 60%, and preferably uses a fireproof polyurethane net with a thickness of 8 - 12 mm. The frame can be made of metal or other materials, and includes a support plate and a pressing strip. The periphery of the support plate is preferably bent. To facilitate fixing the entire current-sharing grid on the fan chassis, convex packages are preferably punched on the support plate. For aesthetic purposes, a panel is preferably installed on the frame. When the fan blows for cooling in the utility model, the wind speed entering each duct of the chassis is more uniform, and the phenomenon of too high chip shell temperature caused by uneven wind speed in a local area no longer exists. The average temperature rise of the entire system is reduced, thereby improving the reliability of the entire system;

[0004] Since some communication equipment is large and the current-sharing grid does not match the size of the communication equipment, multiple current-sharing grids need to be spliced. However, the traditional splicing of current-sharing grids mostly uses bolts for fixation. After the bolts are fixed, it is not convenient for quick disassembly and assembly. Moreover, after the current-sharing grid is used for a long time, the holes inside the current-sharing grid will be blocked by dust, thus affecting the heat dissipation efficiency of the current-sharing grid.
