Abstract
A bank of plates for a heat exchanger, of the type comprising a stack of parallel plates each having smooth-surface edges and an undulated central portion forming, with the associated plates, a dual circuit for countercurrent flow of two independent fluids. The bank is composed of a plurality of superposed elements, each formed by a pair of plates which are joined together. The superposed elements are connected to each other via a continuous or discontinuous longitudinal weld bead.
Claims11
A bank of plates for a heat exchanger, said bank comprising a plurality of superposed elements each formed by a pair of parallel plates, each said pair including an upper plate and a lower plate having contiguous longitudinal edges and transverse edges including at least one contiguous portion, each of said parallel plates including an undulated central portion so as to form, with an associated plate of a said pair of parallel plates, a circuit for current flow of a first fluid, an adjacent pair of parallel plates forming a circuit for countercurrent flow of a second fluid, said superposed elements each formed by a pair of parallel plates being linked to each other by at least one longitudinal spacer arranged between said longitudinal edges of adjacent superposed elements formed by a pair of plates and by a corner cleat arranged at corners of said adjacent superposed elements formed by a pair of plates, said longitudinal edges and said corners of each said pair of plates being fixed to said spacers and said corner cleats by a continuous weld bead extending parallel to a direction of flow of said first and second fluids.
