ABSTRACT:
The invention relates to a fuel preheater, especially for use in diesel engines of motor vehicles, in which the fuel, as a first fluid medium, is heated by absorbing heat from a second fluid medium of higher temperature, and in which the two media are carried through the preheater in separate passages. The preheater has a core which consists substantially of a set of walls of meandering cross section which forms two groups of parallel passages opening alternately on one longitudinal side and the other longitudinal side and running between the individual walls of the set the passages of one group being all open on the same side. The core is disposed between two covers covering the open longitudinal sides of the passages. In the core and/or in at least one of the covers there are disposed, for each of the two media, a distributor passage connecting together the passages of one group at the end side to an inlet from the outside and a collecting passage with an outlet to the outside, plus, at least one a portion of the walls of the core, ribs running substantially perpendicular to the direction of flow of the particular medium and projecting into the interior of the passages.
