METHOD OF HEAT DISSIPATING FOR PLUG-IN BOXES IN CABINET AND AIR-GUIDING APPARATUS

摘要

A method of heat dissipating for plug-in boxes (4, 5, 6) in a cabinet (3), an air-guiding apparatus and communication equipment. The pluralities of plug-in boxes (4, 5, 6) are mounted in the cabinet (3) from top to bottom. At least two branches of airflow for heat dissipating are guided into the plug-in boxes (4, 5, 6). Between two adjacent plug-in boxes, one branch of airflow that passes through a part of the plug-in boxes is guided out of the cabinet (3) and does not pass through the other plug-in boxes. One branch of airflow of at least two branches of airflow for heat dissipating is guided into another part of plug-in boxes to be heat-dissipated, and the airflow that is guided out of the cabinet (3) and the airflow that is guided into the cabinet (3) are intercrossed and separated each other. Therefore, to a certain extent it decreases the overlap of quantity of heat in the cabinet (3) along the direction of the airflow, and a plurality of plug-in boxes (4, 5, 6) in the cabinet (3) are heat-dissipated effectively.
