Abstract

Continuous, chaotic convection mixer, convection heat exchanger and convection reactor The invention relates to a device (1), in particular for mixing, for heat exchange or for carrying out reactions, having one or more through-flow elements (2) which have a center line (3) in the direction of flow, wherein the element(s) (2) is/are at least partially shaped or arranged such that the curve (9) formed by the center line(s) (3) approximately satisfies the following parametric representation: ##EQU1## the parameters and constants having the following meaning: PA1 .differential.(t) position vector in a Cartesian coordinate system, PA1 t parameter along the curve (9), -.infin..ltoreq.t.ltoreq.+.infin., PA1 [t] integral fraction of t, PA1 a(t) a radius of curvature (10), where 0<.vertline.a(t).vertline.<.infin., PA1 c(t) a spacing parameter, where 0<.vertline.c(t).vertline.<.infin..
