Power supply device
First Claim
1. A power supply device comprising:
- a housing having a first bottom surface, a first side wall extending upwards from a peripheral edge of the first bottom surface, a second bottom surface provided on the first side wall above the first bottom surface, a second side wall extending upwards from a peripheral edge of the second bottom surface, and a coolant channel provided below the second bottom surface so that coolant flows through the coolant channel;
a main substrate contained in an interior of the housing, wherein electronic components are provided on a first main surface and a part of a second main surface, which is opposite the first main surface, is arranged on the second bottom surface of the housing while facing the second bottom surface; and
a coil component contained in the interior of the housing and electrically connected to the main substrate, whereinthe interior of the housing is delimited into a first space surrounded by the first bottom surface and the first side wall, and a second space provided above the first space and surrounded by the second bottom surface and the second side wall,the coil component is arranged in the first space,the electronic components provided on the first main surface of the main substrate are arranged in the second spacer, andthe coolant channel is provided along the first side wall above the first bottom surface.

Abstract
In a power supply device 1, a first space R1 and a second space R2 are delimited, a coil component 20 is arranged in the first space R1, and heat-generating components and components having weak resistance to heat are arranged in the second space R2. The power supply device 1 is configured to contain the coil component 20 in the first space R1 so that ambient air of the coil component 20 can contact a first side wall 72, which constitutes the first space R1, making it possible to expect discharge of heat to coolant in a coolant channel W via the first side wall 72. Therefore, heat can be discharged from the ambient air of the coil component, the temperature of which has been raised by heat generation, towards the coolant efficiently.
