An intake/outlet passage forming plate is provided with an entrance/exit section onto which an expansion valve is mounted. A first coolant passage communicates between one side of the intake/outlet section and one end of a coolant path and a second coolant passage that connects the other side of the intake/outlet section and the other end of the coolant path via a communicating pipe. With this structure, the shapes of the first and second coolant passages in the intake/outlet passage forming plate can be changed, making it possible to have the entrance/exit section, onto which the expansion valve is mounted, communicate freely with the outflow/inflow sides of the coolant path. Also, by providing a plurality of tanks to communicate between the communicating pipe and the tank groups at one end of the coolant path, and by changing the communicating positions, the heat exchanging capacity is improved.
