ABSTRACT:
A heat exchanger includes first tubes and a second tube in a casing. The first tubes and the second tube are arranged in layers such that first spaces are provided between the adjacent first tubes and a second space is defined on a periphery of the second tube. Ends of the first tubes and the second tube are connected to a core plate such that first fluid passages defined inside of the first tubes and the second tube are in communication with a connection flange and the first and second spaces are separated from the connection flange. The casing includes an expansion that is in communication with the first spaces, and a side wall that is in contact with a side wall of an end first tube that is located adjacent to the second tube such that the second space is separated from the first spaces and the communication chamber.
