Title
(EN) HEAT TRANSFER PLATE AND GASKET
(FR) PLAQUE DE TRANSFERT DE CHALEUR ET JOINT D'ÉTANCHÉITÉ
Abstract
(EN)
A heat transfer plate (2) and a gasket (5) are provided. The heat transfer plate (2) comprises at least one first port hole area (44) and opposing front and back sides (4, 6), first and second planes (38, 40) defining the extension of the heat transfer plate (2). Each of said at least one first port hole area (44) comprises a first port hole (48) defined by an annular first inner edge (50) of the heat transfer plate (2), said first inner edge (50) consisting of a first and a second section (52, 54). Each of said at least one first port hole area (44) further comprises an annular first inner port portion (56) extending along the first and second sections (52, 54) of said first inner edge (50). The heat transfer plate (2) is characterized in that the first inner port portion (56) comprises, as seen from the front side (4) of the heat transfer plate (2), a number > 1 of first support projections (62) along the second section (54) of the first inner edge (50), each of said number of first support projections (62) comprising a first top portion (64) extending in the first plane (38), and the heat transfer plate (2) extends, within the first inner port portion (56) and outside said number of first support projections (62), at a distance ≠ 0 from the first and second planes (38, 40).
(FR)
L'invention concerne une plaque de transfert de chaleur (2) et un joint d'étanchéité (5). La plaque de transfert de chaleur (2) comprend au moins une première zone à orifices (44) et des côtés avant et arrière opposés (4, 6), des premier et second plans (38, 40) définissant l'extension de la plaque de transfert de chaleur (2). Chaque première zone à orifices (44) comprend un premier orifice (48) défini par un premier bord interne annulaire (50) de la plaque de transfert de chaleur (2), ledit premier bord interne (50) consistant en une première et une seconde section (52, 54). Chaque première zone à orifices (44) comprend en outre une première partie annulaire (56) d'orifice interne s'étendant le long des première et seconde sections (52, 54) dudit premier bord interne (50). La plaque de transfert de chaleur (2) est caractérisée en ce que la première partie (56) d'orifice interne comprend, comme vu depuis le côté avant (4) de la plaque de transfert de chaleur (2), un nombre > 1 de premières saillies de support (62) le long de la seconde section (54) du premier bord interne (50), chaque saillie parmi ledit nombre de premières saillies de support (62) comprenant une première partie supérieure (64) s'étendant dans le premier plan (38), et la plaque de transfert de chaleur (2) s'étend, à l'intérieur de la première partie (56) d'orifice interne et à l'extérieur dudit nombre de premières saillies de support (62), d'une distance ≠ 0 à partir des premier et second plans (38, 40).
