Definitions

  • the present invention relates to a heat exchanger
  • a heat exchanger of the crossflow type construction of a plurality of equally spaced parallel plates having corresponding pairs of their opposite edges bent toward one another and seamed to gether to provide opposite side walls cooperating with adjacent plates to define a series of channels for the passage of two heat exchange media, the side walls of alternate channels being disposed at right angles to the side walls of the other channels so that flow of one heat exchange medium through said alternate channels takes place at right angles to the flow of the other medium through said other channels.
  • the adjacent channels convey two separated media, between which media heat is exchanged from the heating medium to the medium to be heated directly through the plates which define the channels, and it will be obvious that any direct mixing of the media is to be avoided. as such mixing would result in a reduction of the ef flciency of the heat exchanger.
  • the present invention has as one of its objects, the provision of means for eliminating leakage between the edges of two mutually adjacent channels.
  • the present invention is characterized by the provision of a U-shaped channel member disposed along a marginal edge of the heat exchanger and extending transversely of all of said channels, said U-shaped channel member having its open side facing outwardly with one of its legs resting on the side walls defining alternate channels, and said one leg having its free or outer edge extending coincident to a line along the marginal edge of the heat exchanger and welded along said marof the walls defining said ginal edge to the end edges channels, the U-shaped channel member and the welded seam serving to seal the marginal edge of the heat exchanger and to prevent leakage of the heat exchange media between the edges of two mutually adjacent channels.
  • the present invention is also characterized by the provision of a channel iron of L-shaped cross section, one flange of which is passed through the open side of the aforementioned U-shaped channel member and is disposed between the legs thereof, and the other flange of which is provided with spaced holes for the reception of bolts or like fastening means, whereby said channel iron may be secured to a suitable framework or support and thus serve as a means for supporting the heat exchanger in operative position.
  • the reference letters A designate the channels or spaces of the heat exchanger through which the passage of the heat exchange medium has a vertical direction of flow as indicated by the arrows V.
  • the reference letters B designate, on the other hand, the channels or spaces of the heat exchanger through which the passage of the heat exchange medium has a horizontal direction arly indicated by the arrows V and H appearing in the accompanying drawing.
  • a U-shaped channel member 1 extends along a marginal edge of the heat exchanger and is disposed transversely of all the channels, said U-shaped channel member having its open side facing outwardly, and having one of its side flanges resting on the side walls of alternate channels B, B.
  • the free or outer edge of the said one flange extends coincident to a line along said marginal edge and is welded as indicated by the reference numeral 2 to the alined edges 5a, 5b and 6a, 6b of the side walls of channels B and A, respectively.
  • the U-shaped channel member 1 and the welded seam 2 serve to seal the marginal edges of the channels A and B of the heat exchanger and prevent leakage of the heat exfhange media between the edges of two adjacent channe s.
  • the other flange of angle iron 3 i. e. the vertical flange as viewed in the accompanying drawing, projects downwardly in spaced parallel relation to the adjacent side of the heat exchanger below said marginal edges, said downwardly projecting flange having holes therein by means of which the angle iron may be bolted or otherwise secured to a framework or other supporting structure, whereby said angle iron, due to its engagement between the flanges of the U-shaped channel member 1, serves as a means for supporting the heat exchanger.
  • I extend the outer, end wall of the outermost channel A above the top of the heat exchanger and bend this extended portion outwardly at right angles to the plane of said outer end wall to form an outwardly extending, horizontal flange 9 which overlies the horizontal flange of a second angle iron 8 secured to a suitable framework or support.
  • aplurality ofequally spaced'parallel .plates havingcorresponding pairs of their opposite edges bent toward one another. and. seamed together to provide. opposite side walls cooperating with adjacent plates, to define aseries of channels for the passage of two heat exchange media, the side walls of alternate channels being disposed at right angles re the side walls of the other channels so that flow of one heat exchange medium through said alternate channels takes place at right angles to flow of the other medium through said other channels
  • a U shaped channel member secured along one marginal edge of the heat exchanger and extending longitudinally along said marginal edge and transversely of all of said channels, said U-shaped channel member having its open side facing outwardly with respect to the adjacent side of said heat exchanger and having one of its flanges resting onthe side walls of the alternate channels and said one flange having its free edge extending coincident to a line along said one marginal edge and welded to the end edges of the side walls defining said channels, and an angle iron of substantially L-shaped transverse cross
