Abstract
A tube has a plurality of coolant passages inside which are separated by inner struts at center into an inlet passage side and an outlet passage side in the longitudinal direction of a core. On one end side of the tube inserted in a header are formed an inlet port and an outlet port through the tube in the direction of core lamination on either of the inlet passage side and the outlet passage side. Inside the header is disposed a separator, with the tube in an inserted state, in a position for separation between the inlet port and the outlet port of each tube. Since the header interior is divided to the front and rear sides of the core, there are formed, in the header, an inlet chamber communicating with a coolant passage on the inlet passage side through an inlet port, and an outlet chamber communicating with a coolant passage on the outlet passage on the outlet side through the outlet port.
