Title (EN) HEAT EXCHANGER
(FR) ÉCHANGEUR DE CHALEUR
Abstract:
(EN) A heat exchanger (4) has fluid flow channels (6) with at least one heat exchanging surface (10) which has an undulating surface section for which the surface profile varies along a predetermined direction such that at a first edge (E1) the surface profile follows a first transverse wave (20), at a second edge (E)2 the surface profile follows a second transverse wave (22) and at an intermediate point I between the edges the surface profile follows a third transverse wave (24). The third transverse wave (24) has a different phase, frequency or amplitude to the first and second transverse waves so that chevron-shaped ridges and valleys are formed. This improves the mixing of fluid passing through the channel and hence the heat exchange efficiency.
(FR) La présente invention concerne un échangeur de chaleur (4) comportant des canaux d'écoulement de fluide (6) dotés d'au moins une surface d'échange de chaleur (10) qui a une section surface ondulée pour laquelle le profil de surface varie le long d'une direction prédéfinie de telle sorte qu'au niveau d'un premier bord (E1), le profil de surface suit une première onde transversale (20), qu'au niveau d'un second bord (E2), le profil de surface suit une deuxième onde transversale (22), et qu'au niveau d'un point intermédiaire I entre les bords, le profil de surface suit une troisième onde transversale (24). La troisième onde transversale (24) présente une phase, une fréquence ou une amplitude différente par rapport aux première et deuxièmes ondes transversales de telle sorte que des crêtes et des creux en forme de chevron sont formés. Ceci améliore le mélange de fluide traversant le canal et, par conséquent, l'efficacité d'échange de chaleur.
