<P>PROBLEM TO BE SOLVED: To reduce draft resistance of air introduced to an air inlet of a centrifugal blower from another end side of a lower face of a substrate housed in a housing in which housing height is made lower as it goes from one end side to the other end side. <P>SOLUTION: An electronic device has: a body housing 24 whose housing height is made lower as it goes from a back wall to a front wall; and a motherboard 104 housed in the body housing 24 along an upper wall 24A of the body housing 24 in which an electronic component is mounted on a lower face 104A facing a second lower wall part 24H of the body housing 24, and an opening 104B penetrating in a plate thickness direction is formed. Further, the electronic device has a centrifugal fan 140 including air inlets 148A, 148B provided on both sides in an axial direction of a moving blade with the plate thickness direction of the substrate being the axial direction and arranged in the opening 104B. A distance between an edge part 148C of a front wall side D5 in the respective air inlets 148A, 148B and the upper wall 24A is shorter than a distance between an edge part 148D of a back wall side D4 in the respective air inlets 148A, 148B and the upper wall 24A. <P>COPYRIGHT: (C)2013,JPO&INPIT |
