Abstract

The invention relates to a heat exchanger (or a motor vehicle, comprising a first flow path (1) with a number of flow conduits (6) for conducting a fluid to be cooled, a deflection region (13), situated downstream of the first flow path (1) and a second flow path (2), situated downstream ol the deflection region (13). According to the invention, the flow conduits (6) of the first flow path (1) continue in the deflection region (13) and the second (low path (2) as continuous separate flow conduits (6). The invention also relates to a flow conduit (41, 41′, 61, 61′, 71, 71′, 81, 81′, 91, 91′) for a heat exchanger (30,40) for exchanging heat between a first fluid (31) and a second fluid (33). The aim of the invention is to guarantee an improved transfer of heat with a simultaneous acceptable pressure drop, whilst reducing the blocking risk.
