Patent ID: 8817470

Claim:
An electronic device comprising: a circuit board having a component mounted thereon; a first side plate that includes an air intake port that introduces cooling air over the circuit board; and a second side plate that includes an air discharge port that discharges the cooling air from the circuit board, wherein the first side plate includes the air intake port at a position shifted from a position closest to the component, a direction in which the position of the air intake port is shifted corresponds to an angle of an intake stream of the cooling air with respect to the first side plate, the cooling air is supplied via an air intake duct at a predetermined angle that is greater than 0 degrees and less than 90 degrees with respect to the air intake port, and the first side plate includes the air intake port at the position where a center of the air intake port in a lengthening direction of the first side plate is arranged by offsetting toward an upstream side of the cooling air supplied to the air intake port against a center of the component in the lengthening direction of the first side plate.
