<p>PROBLEM TO BE SOLVED: To provide an electric power conversion system which efficiently cools a semiconductor module.SOLUTION: An electric power conversion system 1 includes: a semiconductor module 2; a cooler 3 which cools the semiconductor module 2; and a pressing member 4 which holds the semiconductor module 2 with a cooling tube 32. The cooler 3 includes: the cooling tube 32 having a cooling surface 31 which contacts with the semiconductor module 2; and a pair of pipes 331, 332 which introduces/discharges a cooling medium into/from a refrigerant passage 321 formed in the cooling tube 32. The pressing member 4 includes: a module contact surface 41 which contacts with the semiconductor module 2; and pipe contact parts 42 which contact with the pair of pipes 331, 332. The pipe contact parts 42 respectively include groove-like recessed surfaces 421 formed along outer peripheral side surfaces of the pipes 331, 332. The groove-like recessed surfaces 421 make surface contact with the pipes 331, 332.</p> |
