| 1. A wind velocity measuring device for inclusion in an electronic apparatus including cooled objects and cooling fans for
cooling the cooled objects and measuring a wind velocity of air blown to the cooled objects, the wind velocity measuring device
comprising:
a wind velocity measuring unit that measures a wind velocity of air; and
an air circulating unit that circulates a portion of the air blown to the cooled objects,
wherein the air circulating unit includes a wind velocity measurement channel that receives inner air at a front stage side
of the circulation direction of the air previous to cooling the cooled objects, and barrier portions that extend to cross
the wind velocity measurement channel and an exhaust port that discharges the inner air provided by the wind velocity measurement
channel to the outside, and
the wind velocity measuring unit measures a wind velocity of the air within the wind velocity measurement channel between
the barrier portions and the exhaust port of the air circulating unit.
