Title (EN) A HEAT EXCHANGER PLATE, A PAIR OF TWO HEAT EXCHANGER PLATES, AND PLATE PACKAGE FOR A PLATE HEAT EXCHANGER
(FR) PLAQUE D’ÉCHANGE THERMIQUE, PAIRE DE DEUX PLAQUES D’ÉCHANGE THERMIQUE ET ENSEMBLE DE PLAQUES POUR ÉCHANGEUR THERMIQUE À PLAQUES
Abstract:
(EN) The invention refers to a heat exchanger plate (11 ), a pair of heat exchanger plates, and a plate package for a plate heat exchanger. Each heat exchanger plate comprises a heat transfer area (33) and a distribution area (34) which adjoins the heat transfer area along a borderline (35). The distribution area has projections and depressions abutting depressions and projections, respectively, on a distribution area of adjacent heat exchanger plates. The heat transfer area has projections (51 ) and depressions (52) abutting depressions and projections, respectively, on a heat transfer area of adjacent heat exchanger plates for forming first contact surfaces positioned at a first distance from each other along a direction substantially parallel with the borderline. The heat transfer area comprises a transition area (58), which adjoins the distribution area along the borderline and has projections and depressions abutting depressions and projections, respectively, of a heat transfer area of adjacent heat exchanger plates for forming second contact surfaces at a second distance from each other along the first direction. The sec- ond distance is significantly shorter than the first distance.
(FR) L’invention concerne une plaque d’échange thermique (11), une paire de plaques d’échange thermique et un ensemble de plaques pour échangeur thermique à plaques. Chaque plaque d’échange thermique comprend une zone de transfert thermique (33) et une zone de distribution (34) jouxtant la zone de transfert thermique le long d’une ligne de séparation (35). La zone de distribution présente des projections et des dépressions aboutant contre des dépressions et des projections, respectivement, sur une zone de distribution de plaques d’échange thermique adjacentes. La zone de transfert thermique possède des projections (51) et des dépressions (52) aboutant contre des dépressions et des projections, respectivement, sur une zone de transfert thermique de plaques d’échange thermique adjacentes pour constituer de premières surfaces de contact positionnées à une première distance l’une de l’autre dans une direction sensiblement parallèle à la ligne de séparation. La zone de transfert thermique comprend une zone de transition (58), jouxtant la zone de distribution le long de la ligne de séparation et possède des projections et des dépressions aboutant contre des dépressions et des projections, respectivement, d’une zone de transfert thermique de plaques d’échange thermique adjacentes pour constituer de secondes surfaces de contact à une seconde distance l’une de l’autre dans la première direction. La seconde distance est notablement plus courte que la première distance.
