ABSTRACT:
A communication device which has high cooling efficiency and can be reduced in size and weight. The communication device in which a plurality of electronic circuit boards are mounted to a back wiring board (BWB) includes a casing containing the electronic circuit boards as a unit, an intake fan unit for introducing air into the casing to cool the electronic circuit boards, and a discharge fan unit having a plurality of blower fans each arranged such that air intake and discharge directions thereof form an angle of nearly 90 degrees, the blower fans discharging the air introduced into the casing. Combined use of an axial fan and the blower fans permits air to be introduced into and discharged from the casing from rear and front sides, respectively, of the casing, whereby spaces that the fan units occupy in the communication device can be reduced.
