1. A semiconductor device comprising:
- a coolant jacket comprising a passage through which a coolant flows inside said coolant jacket;
a first power module mounted on a first-surface member of said coolant jacket; and
a second power module mounted on a second-surface member of said coolant jacket, said second-surface member facing said first-surface member,wherein said coolant jacket comprises;
a first fin in contact with said first-surface member in said passage;
a second fin in contact with said second-surface member in said passage;
an intake opening through which said coolant is taken in from an outside;
an intake header configured to send said coolant entering from said intake opening to said first fin and said second fin;
a discharge opening through which said coolant is discharged to said outside; and
a discharge header configured to send, to said discharge opening, said coolant passing through said first fin and said second fin, andwherein said first power module and said second power module face each other through said first-surface member and said second-surface member, and through said first fin and said second fin.

Abstract
Provided is a semiconductor device having a small footprint, where the semiconductor device includes multiple power modules and a cooling structure for these power modules. The semiconductor device includes: a first power module on a first top plate of a coolant jacket; and a second power module on a second top plate of the coolant jacket, where the second top plate face the first top plate. The coolant jacket includes a first fin in contact with the first top plate in a passage, and a second fin in contact with the second top plate in the passage. The power modules face each other through the top plates and the fins.
