Abstract

A fin-type heat transfer device (1), in particular for vehicle applications, has fins (2) stacked onto one another spaced in a stack direction (5), which form a fin stack. The fins each form a plurality of openings (4) surrounded by collars (3), and the collars of adjacent fins are coupled to one another. In the region of the coupled collars, a channel (6), each of a channel system (7) for a first flow path (8) of a first fluid, is formed and between adjacent fins a second flow path (9) of a second fluid is formed, and with end plates (10) on ends of the fin stack that are distant from one another in the stack direction. The channels are fluidically connected to one another within the end plates. The fin-type heat transfer device (1) makes possible a cost-effective and simple production and assembly through a tubeless construction.
