(54)	Automotive heat exchanger

(57) An automotive heat exchanger (1) has respective flowpath arrays (2,3) for a first fluid medium and a second fluid medium (air). A series of tubes (2) for the first fluid medium are formed of joined mating plates (4,5), the tubes (2) having open ends and a flowpath extending between the open ends, adjacent tubes (2) having spaced external surface portions defining the flowpath array (3) for the air fluid medium. The tubes (2) advantageously have relatively wide open mouth portions (4a) leading to a narrower tube width (h) extending between the open ends.
