Title (EN) PLATE‑TYPE HEAT EXCHANGER, PARTICULARLY FOR MOTOR VEHICLES
(FR) ECHANGEUR DE CHALEUR A PLAQUES, NOTAMMENT POUR VEHICULES AUTOMOBILES
Abstract: front page image
(EN)A heat exchanger (10) comprises an alternating stack of first plates (12) and of second plates (14) respectively provided with first corrugations (16) separated from one another by a first spacing (P1) and of second corrugations (18) separated from one another by a second spacing (P2) which is different from the first spacing (P1). This thus defines, between the plates, first circulation passages with a first passage cross section suited to a first fluid (F1) which alternate with second circulation passages which have a second passage cross section suited to a second fluid (F2). The invention applies particularly to heat exchangers for motor vehicles.
(FR)Un échangeur de chaleur (10) comprend un empilement alterné de premières plaques (12) et de secondes plaques (14) munies respectivement de premières ondulations (16) distantes entre elles d'un premier pas (P1) et de secondes ondulations (18) distantes entre elles d'un second pas (P2), qui est différent du premier pas (P1). On définit ainsi, entre les plaques, des premiers canaux de circulation ayant une première section de passage adaptée à premier fluide (F1) qui alternent avec des seconds canaux de circulation ayant une seconde section de passage adaptée à un second fluide (F2). L'invention s'applique en particulier aux échangeurs de chaleur pour véhicules automobiles.
