Claim:
1. A cooling device, comprising: a rectangular parallelepiped housing having a longitudinal axis and in which a plurality of electronic components, including a heat generating electronic component, is housed, the plurality of electronic components being arranged along a longitudinal direction of the housing to have a first end of the electronic components arranged opposite a second end of the electronic components along the longitudinal direction; a plurality of heat-radiating side wall fins formed on an outer surface of a first side wall of the housing so as to each have a side longitudinal axis that extends in parallel with the longitudinal axis of the housing, at least one of the side wall fins extending along the side longitudinal axis thereof from the first end of the electronic components to the second end of the electronic components; a plurality of heat-radiating bottom fins formed on a bottom surface of a bottom portion of the housing so as to each have a bottom longitudinal axis that extends in parallel with the longitudinal axis of the housing, at least one of the bottom fins extending along the bottom longitudinal axis thereof from the first end to the second end; a cover member covering the plurality of heat-radiating side wall fins and the plurality of heat-radiating bottom fins from an outer side, the cover member forming a side wall cooling channel between the plurality of heat-radiating side wall fins, and further forming a bottom cooling channel between the bottom fins; a fluid introduction chamber attached to a second side wall of the housing, the fluid introduction chamber facing in a direction crossing the first side wall, and in a direction to face the second side wall so that the side wall cooling channel and the bottom cooling channel communicate with the fluid introduction chamber; and a coolant supply device externally attached to the chamber and supplying a coolant to the side wall and bottom cooling channels via the fluid introduction chamber, wherein the side wall fins and the bottom fins are formed in predetermined shapes, whereby an amount of the coolant supplied from the coolant supply device to the side wall cooling channel is adjusted and an amount of the coolant supplied from the coolant supply device to the bottom cooling channel is adjusted.
