Abstract: An energy absorbing member (20) is formed of an aluminum alloy extruded material having a substantially quadrangular outer shape. Straight portions of a pair of long sides of a quadrangular shape are each segmented into three side walls (21a, 21b, 21c) by two arcuate internal projections (26) that project inward. Vertices of opposing internal projections (26) are joined by a rib (25). Accordingly, the energy absorbing member (20) is configured to have a shape in which three cylindrical portions having hollow portions (24a, 24b, 24c) are joined. Arc-shaped internal projections (23) that each project inward are provided in four corners of the quadrangular shape.

Abstract: A coolant passageway (2) of a heat sink (1) has a coolant lead-in part (21), a coolant lead-out part (22), coolant-contact parts (23), coolant-transit parts (25), and connecting parts (24). The coolant-contact parts (23) are disposed spaced apart from one another along a coolant path leading from the coolant lead-in part (21) to the coolant lead-out part (22) and are configured such that they bring the coolant into contact with a cooling-wall part. The coolant-transit parts (25) are disposed between adjacent coolant-contact parts (23) and are configured such that the coolant can transit from upstream-side coolant-contact parts (23) to downstream-side coolant-contact parts (23) in the coolant paths. The connecting parts (24) are interposed between the coolant-transit parts (25) and the coolant-contact parts (23) and have a passageway cross-sectional area that is smaller than those of the coolant-contact parts (23) and the coolant-transit parts (25).
