1. a kind of semiconductor module cooler,The semiconductor module cooler provides refrigerant externally to water jacket, and the semiconductor element configured in its outer surface is enteredRow cooling, it is characterised in that including:

  • Radiator, the radiator carry out thermally coupled with the semiconductor element;

    First flow path, the first flow path are configured in the water jacket, and extension is proceeded by from the refrigerant introducing port of upstream side, andGuide portion is configured with, the guide portion, which has, to be used to guide inclination of the refrigerant to a side flow of the radiatorFace;

    Second flow path, the second flow path to be configured side by side and in a manner of interval in the water jacket with the first flow path,The second flow path extends towards refrigerant outlet, and formed with the side wall parallel with another side of the radiator;

    3rd stream, the position of the connection first flow path and the second flow path that the 3rd stream is formed in the water jacketPut, and be configured with the radiator;

    AndFlow velocity adjustable plate, the flow velocity adjustable plate are configured in the second flow path, and are formed as described another with the radiatorOne side interval and it is parallel to each other,The refrigerant introducing port and the refrigerant outlet are formed on the same wall of the water jacket,From the 3rd stream discharge refrigerant flow velocity due to this from the refrigerant impingement flow speed adjustable plate that the 3rd stream is discharged whenCaused pressure and reduce.
