<P>PROBLEM TO BE SOLVED: To provide a technology for reducing the weight of a radiator while maintaining the cooling performance. <P>SOLUTION: Regions A-D surrounded by solid lines show the areas of a radiator 60 having different fin pitches. The areas A-D are determined according to the amount of travel wind at respective positions of the radiator 60. The area A is a small fin pitch area having a fin pitch of 2.00 mm. The area B is a medium fin pitch area having a fin pitch of 2.75 mm. The area C is a large fin pitch area having a fin pitch of 3.50 mm. The area D is a still larger fin pitch area having a fin pitch of 4.00 mm. As a whole of the radiator, the weight of the radiator is reduced while maintaining the cooling performance. <P>COPYRIGHT: (C)2013,JPO&INPIT |
