<p><P>PROBLEM TO BE SOLVED: To simplify assembling of a heat exchanger. <P>SOLUTION: This heat exchanger (10) includes at least one header box (12, 14) delimiting a first chamber (42) for a first fluid (F<SB>1</SB>) and a second chamber (44) for a second fluid (F<SB>2</SB>), as well as a core (16) of tubes ending into the header box (12, 14) and comprising at least one first tube (18) communicating with the first chamber (42) of the collecting box (12, 14) and at least one second tube (20) communicating with the second chamber (44) of the collecting box (12, 14), the first tube (18) being coupled with the second tube (20) to constitute a module (22) allowing a heat transfer between the first tube (18) and the second tube (20). Ends (32) of the second tube (20) are off-set with respect to ends (30) of the first tube (18), so that the ends (30) of the first tube (18) and the ends (32) of the second tube (20) can be received in an alternate way in insertion holes (34) of the header box (12, 14), the holes (34) being spaced with a constant pitch (P). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
