SEMICONDUCTOR COOLING APPARATUS
First Claim
1. A semiconductor cooling apparatus comprising:
- a tank forming body, the tank forming body including;
a first outer plate;
a second outer plate;
a middle plate arranged between the first outer plate and the second outer plate, an outer periphery of the first outer plate and an outer periphery of the second outer plate being brazed to the middle plate;
a first inner fin with a corrugated plate-like shape arranged between the first outer plate and the middle plate, the first inner fin being brazed to at least one of the first outer plate and the middle plate, a first cooling medium passage being defined between the first outer plate and the first inner fin, a second cooling medium passage being defined between the first inner fin and the middle plate; and
a second inner fin with a corrugated plate-like shape arranged between the second outer plate and the middle plate, the second inner fin being brazed to at least one of the second outer plate and the middle plate, a third cooling medium passage being defined between the second inner fin and the middle plate, a fourth cooling medium passage being defined between the second outer plate and the second inner fin, the middle plate having at least one through hole through which the second cooling medium passage and the third cooling medium passage communicate with each other; and
semiconductor power device mounting substrates each brazed to an outer surface of one of the first outer plate and the second outer plate, each semiconductor power device mounting substrate having an insulating substrate and metal layers formed on both surfaces of the insulating substrate, each semiconductor power device mounting substrate having a first surface on which a semiconductor power device is mounted and a second surface brazed to one of the first outer plate and the second outer plate.

Abstract
A semiconductor cooling apparatus having a tank forming body and semiconductor power device mounting substrates is disclosed. The tank forming body includes a first outer plate, a second outer plate, a middle plate, a first inner fin, and a second inner fin. The middle plate is brazed to the outer periphery of the first outer plate and the outer periphery of the second outer plate. The first inner fin is brazed to the first outer plate. A first cooling medium passage is defined between the first outer plate and the first inner fin. A second cooling medium passage is defined between the first inner fin and the middle plate. The second inner fin is brazed to the second outer plate. A third cooling medium passage is defined between the second inner fin and the middle plate. A fourth cooling medium passage is defined between the second outer plate and the second inner fin. The middle plate has a plurality of through holes through which a second cooling medium passage and a third cooling medium passage communicate with each other. Each one of the mounting substrates includes a first surface on which a semiconductor power device is mounted and a second surface brazed to one of the first outer plate and the second outer plate.
