A plate type heat exchanger (10), particularly a liquid cooled charge air cooler for an internal combustion engine, comprising a stack (12) of pairs (14, 18) of plates (16, 20, 22), each pair of plates having mating edges and a concave region delimited by said edges to define a fluid passage between said pair of plates, said plates having tubular projections defining an inlet for entering fluid to said passage and an outlet for exiting fluid from said passage to thereby establish a direction of fluid flow, said stack (12) having a pair (18) of end plates (20, 22) which are fixed together, said pair (18) of end plates (20, 22) defining an inlet and an outlet tubular portions to be connected with the inlet and outlet of the other plates (16), on one side, and to an inlet and outlet connecting pipes (38, 40), on the other side, characterized in that at least one insert piece is arranged between the two end plates (20, 22), around the inlet and outlet tubular portions, in order to reinforce the assembly of the two end plates (20, 22) in the region of inlet/outlet connection. |
