PROBLEM TO BE SOLVED: To increase the efficiency of cooling a plurality of heating elements in a housing. SOLUTION: The outside air taken in by a cooling fan 110A is sent from an inlet port 201A to a guide portion 202A and flown along the guide portion 202A. One part of the air is exhausted from an exhaust port 203A and the other part of the air is exhausted from a branch port 204A. The air exhausted from the exhaust port 203A cools a heat sink 121A. The air exhausted from the branch port 204A cools a heat sink 141A. The duct can be applied, for example, to a cooling duct for electronic apparatus. COPYRIGHT: (C)2009,JPO&INPIT |
