Title
(EN) HEAT TRANSFER PLATE
(FR) PLAQUE DE TRANSFERT DE CHALEUR
Abstract
(EN)
A heat transfer plate (2a) is provided. It comprises a first end portion (8), a second end portion (16) and a center portion (24) arranged in succession along a longitudinal center axis (L) of the heat transfer plate (2a). The center portion (24) comprises a heat transfer area (26) provided with a heat transfer pattern comprising support ridges (60) and support valleys (62). The support ridges (60) and support valleys (62) longitudinally extend parallel to the longitudinal center axis (L) of the heat transfer plate (2a). The support ridges (60) and support valleys (62) are alternately arranged along a number = x of separated imaginary longitudinal straight lines (64) extending parallel to the longitudinal center axis (L) of the heat transfer plate (2a) and along a number of separated imaginary transverse straight lines (66) extending perpendicular to the longitudinal center axis (L) of the heat transfer plate (2a). The heat transfer pattern further comprises turbulence ridges (68) and turbulence valleys (70). The heat transfer plate (2a) is characterized in that at least a plurality of the turbulence ridges (68) and turbulence valleys (70) along at least a center portion (68a, 70a) of their longitudinal extension extend inclined in relation to the transverse imaginary straight lines (66).

L'invention concerne une plaque de transfert de chaleur (2a). Ladite plaque comprend une première partie d'extrémité (8), une seconde partie d'extrémité (16) et une partie centrale (24) agencées successivement le long d'un axe central longitudinal (L) de la plaque de transfert de chaleur (2a). La partie centrale (24) comprend une zone de transfert de chaleur (26) munie d'un motif de transfert de chaleur comprenant des crêtes de support (60) et des creux de support (62). Les crêtes de support (60) et les creux de support (62) s'étendent longitudinalement parallèlement à l'axe central longitudinal (L) de la plaque de transfert de chaleur (2a). Les crêtes de support (60) et les creux de support (62) sont agencés en alternance le long d'un nombre = x de lignes droites longitudinales imaginaires séparées (64) s'étendant parallèlement à l'axe central longitudinal (L) de la plaque de transfert de chaleur (2a), et le long d'un certain nombre de lignes droites transversales imaginaires séparées (66) s'étendant perpendiculairement à l'axe central longitudinal (L) de la plaque de transfert de chaleur (2a). Le motif de transfert de chaleur comprend en outre des crêtes de turbulence (68) et des creux de turbulence (70). La plaque de transfert de chaleur (2a) est caractérisée en ce qu'au moins une pluralité des crêtes de turbulence (68) et des creux de turbulence (70), le long d'au moins une partie centrale (68a, 70a) de leur extension longitudinale, s'étendent de manière inclinée par rapport aux lignes droites imaginaires transversales (66).
