Abstract

Un échangeur de chaleur comprend une structure de division conçue pour définir, au moins en partie, un premier volume et un second volume. La structure de division est conçue pour permettre un écoulement d'un fluide de travail entre le premier volume et le second volume et conçue pour commander un rapport d'une pression amont dans le premier volume sur une pression aval dans le second volume par induction d'une résistance aérodynamique dans un écoulement du fluide de travail entre le premier volume et le second volume. Dans certains modes de réalisation, l'écoulement du fluide de travail entre le premier volume et le second volume s'effectue le long d'un trajet d'écoulement de retour défini au moins en partie par la structure de division, et le trajet d'écoulement de retour est un trajet sinueux ou convoluté.
