ABSTRACT:
A cooler-equipped printed circuit board, in which electronic devices arranged in a matrix form on the printed circuit board are covered with a sealed case held in liquidtight contact with the board and having a coolant channel from an inlet port and an outlet port made in the case. Barriers are provided in the coolant channel to change the direction of flow of the coolant to stir it and make its temperature uniform throughout it.
