Provided are a make-up air ventilation method and device for a single board panel with forward and reverse ventilation air ducts. The method comprises: inserting single boards (21) in a front and back arrangement into a shelf (11), wherein the single board (21) in the shelf (11) is provided with a forward air duct and a reverse air duct, wherein both air ducts are venting air ducts, and wherein a make-up air ventilation hole (210) is disposed at two ends of a single board panel for make-up air ventilation; and using two rows of blocking members (31, 32) to block the make-up air ventilation holes (210) on a front face and a rear face of the shelf (11) at a side near a shelf fan (110), wherein one of the blocking members (31, 32) corresponds to one of the single boards (21) inserted into a slot of the shelf. Under a complex architecture where single boards with forward and reverse ventilation air ducts are arranged in a front-and-back system or a single-plane orthogonal system, the invention realizes an enhancement of make-up air ventilation and heat dissipation of a panel and overcomes an inability of providing make-up air ventilation in the two systems due to a specific air duct arrangement of the single board. The invention thereby improves a heat dissipation capacity of the single board and the system, improves product competitiveness, and is able to prevent human error and enhance reliability.
Description
technical field [0001] The invention relates to the field of single-board box inserts, in particular to a method and device for replenishing air on a single-board front and back ventilation duct panel. Background technique [0002] With the continuous improvement of the forwarding capability of bearer network products, the product architecture has appeared a single-board front-to-back insertion system and a single-sided mirrored orthogonal system. The single board has two layout directions in the same subrack. The complex system architecture and heat dissipation system make the single There are two directions of board-level air ducts, namely, from right to left and from left to right. Especially when the two board-level air ducts are exhaust air ducts, if you want to open holes in the panel to supplement air and enhance heat dissipation, air ducts will appear. Short circuit problem. [0003] figure 1 It is a schematic diagram of the short circuit of the air duct caused by ...
