HEAT RADIATION STRUCTURE OF RACK-MOUNT APPARATUS

PROBLEM TO BE SOLVED: To obtain higher heat radiation effect of a heat radiation structure of a rack-mount apparatus through easier shielding of heat by saving the number of assembling processes with a simplified structure and improving mounting efficiency. SOLUTION: Within the internal side of the rack body 1 including a front door 2 and a rear door 3, a plurality of racks 6 are provided and heat convection plates 7 are also provided among the racks 6, and each rack 6 accommodates a plurality of printed circuit boards 5 on which electronic components are mounted. The heat convection plate 7 is formed by integrating the heat convection part 8, and a rack guide 9 having both end-portions of U-shape and the heat convection part 8 is inclined toward the lower side 11 of the rear surface of the upper stage rack 6b from the upper side 10 of the front surface of the lower rack 6a. The heat generated from the printed circuit board 5 in the rack 6 is guided to rise along the heat convection plate 7 giving no influence on the upper stage rack and is radiated to the external side. Since each rack 6 is mounted on the rack guide 9 and is supported thereby, the number of assembling steps can be reduced. COPYRIGHT: (C)2004,JPO&NCIPI
