Abstract

A heat exchanger arrangement ( 2 ) comprises at least one heat exchanger ( 4 ) including at least one substantially horizontally oriented manifold ( 6 a, 6 b ) forming an upper side of the at least one heat exchanger ( 4 ), the at least one manifold ( 6 a, 6 b ) having lateral end portions ( 8 ); and a support structure ( 10 ) including a main portion comprising, at least partially, a metallic material, and manifold support portions ( 14 ) associated to respective lateral end portions ( 8 ) of the at least one manifold ( 6 a, 6 b ). The manifold support portions ( 14 ) are made at least partially from a non-metallic material and configured to receive the lateral end portions ( 8 ) of the at least one manifold ( 6 a, 6 b ) for preventing the at least one manifold ( 6 a, 6 b ) from contacting any metallic portions of the support structure ( 10 ).
