  • Publication number: 20220170701
    Abstract: A direct heat exchange and material transfer apparatus having a plurality of columns, a single stack of at least two solid metal plates of rectangular section, the plates being substantially all of the same shape and dimensions and parallel to a determined direction, each plate being separated from the adjacent plate, at least in a first direct heat exchange and material transfer zone of the apparatus, by a group of hollow metal columns that are aligned and have a section which is polygonal and has at least two parallel surfaces, the channels being parallel to the determined direction and contiguous with one another, the columns of each group each being in contact with the two metal plates on either side of the group, at least some of the columns of a group containing a material and heat exchange means.

  • Publication number: 20220134304
    Abstract: A method for manufacturing a heat and material exchange apparatus having a plurality of columns and by a series of at least three metal plates of rectangular section, the plates being substantially all of the same shape and dimensions, each plate being separated from the adjacent plate by a group of hollow metal columns that are aligned and have a section which is polygonal, the columns of each group being parallel to one another, at least some of the columns of a group containing a material and heat exchange means, at least the parts of the plates which are in contact with the columns being coated with a brazing material wherein the plates are secured to the columns by placing the exchange apparatus in a furnace and by heating the furnace in order to braze the apparatus to form a parallelepipedal block.

  • Publication number: 20220082448
    Abstract: The invention relates to a heat exchanger of the brazed plate and fin type comprising a stack of plates arranged parallel to one another and to a longitudinal direction so as to define, between the plates, a plurality of passages suitable for the flow of at least a first fluid in the longitudinal direction, at least one exchange structure of corrugated shape being arranged between two successive plates and having corrugation crests and corrugation troughs connected alternately by a succession of fins.

  • Publication number: 20220011052
    Abstract: The invention relates to a method for manufacturing a brazed plate type heat exchanger comprising the following steps: a) stacking, with a clearance, a plurality of plates parallel to each other so as to define, between said plates, a plurality of passages suitable for the flow of at least one fluid, said passages being delimited by peripheral edges and at least one passage comprising at least one zone to be supported emerging towards the outside of the passage through at least one opening of a peripheral edge; b) arranging at least one support member in the zone to be supported; c) brazing the stack of plates comprising the support member; and d) removing the support member from the zone to be supported through the opening. According to the invention, the support member is deformable and, in step d), a traction force is exerted on the support member so as to cause a deformation in at least one part of the support member and a translation movement of the support member towards the outside of the passage.
