Title: Plate-fin panel heat exchanger and panel components thereof

Abstract

A plate-fin panel for a heat exchanger may be either formed as an aluminum extrusion or fabricated from a corrugated metal sheet sandwiched between two flat metal sheets. The extruded aluminum version may be clad with protective sheet metal jackets made of, or coated with, a corrosion resistant Cu-Ni alloy. Individual panel sections can be joined together by tongue and groove engagement to obtain a total desired panel width if available extrusion press or rolling mill capacity is insufficient. The plate-fin panels are assembled into slotted headering plates, and a layer of synthetic plastics potting compound seals dissimilar metal joints against electrolytic corrosion as well as leakage and provides sufficient adhesive strength to reduce or eliminate the need for welding the panels to the headers. Mechanical brush or hydraulic jet apparatus is capable of continuously or intermittently cleaning slime or encrustations from all panel surfaces exposed to seawater.

  • This patent describes a stackable plate heat exchanger comprising heat exchange plates made from sheet metal. Each of the heat exchange plates has a center part which is used for heat exchange and is provided with parallel wavelike impressions which extend transversely to a longitudinal axis of the plate. The wavelike impressions of neighboring plates cross one another, the wavelike impressions being in juxtaposition to each other and being arranged in circular wave fields which are dense and cover substantially the center part of the plate. Wavelike impressions form a predetermined angle with respect to the longitudinal axis of themore » plate, whereby a heat exchanger having a predetermined thermal length is obtained.« less
  • A fluidized bed is disclosed heat exchanger having a perforated support plate supporting relatively lightweight absorbent material particles and relatively heavy fuel ash particles includes a drain through which a flow of air defining a separating air screen retains the adsorbent material particles in the bed but allows the fuel ash particles to fall into the drain.
  • In a heat exchanger panel for use in a solar energy collector system, said panel comprising a plurality of spaced parallel individual tubular passageways connecting opposed headers defined by numerous island-like bonded portions connected by a plurality of tubular channels passing therebetween, the boundaries of said headers defining a generally triangular shape with at least one of said boundaries being inclined with respect to an edge of said panel, said headers including entry and exit portions to said panel, siad entry and exit portions being laterally displaced from the center of said panel to permit a heat exchange medium tomore » flow into said panel and across said headers so that said medium flows through each of the plurality of spaced parallel indiviual tubular passageways connecting said headers; and said parallel individual tubular passageways being interconnected by further tubular interconnecting portions spaced from said headers the improvement wherein said tubular interconnecting portions are arranged across said panel at an inclination generally corresponding to the inclination of said at least one boundary.« less
  • The ornamental design for a three tube heat exchanger panel, as shown and described.
  • A heat exchanger assembly is described for a gas fired furnace and the like comprising: a heat exchanger unit including opposed clamshell sections joined to each other to form an enclosure defining a combustion chamber; an opening into the chamber delimited by a substantially continuous rim formed by wall portions of the opposed sections, the rim being delimited by means forming a shoulder extending in a radial direction internally around the opening in the heat exchanger unit; and a plate member having an opening therein corresponding to the opening in the heat exchanger unit and delimited by a seamless flangemore » extending around the opening in the plate member. The flange is proportioned to fit within the opening in the heat exchanger unit. It extends into the chamber and is folded radially outwardly with respect to a central axis of the opening in the plate member into an expanded metal engagement with a backsurface of the means forming the shoulder in the heat exchanger unit to form a substantially rigid leakproof joint between the heat exchanger unit and the plate member. A method is described of securing a heat exchanger unit for a furnace to a plate member, comprising providing the heat exchanger unit as a relatively thin walled sheet metal structure defining a chamber for the flow of fluid to be in heat exchange relationship with the walls of the heat exchanger unit and, at least one opening into the chamber through a wall of the heat exchanger unit.« less
