Definitions

  • Heat-exchangers of conventional type comprise two sets of fluid channels separated by heat conducting walls, such as metal walls, whereby a hot fluid passing through one set of channels transfers some of its heat through the walls to a cooler fluid passing through the other set of channels.
  • the fluid may be a liquid, a vapour or a gas.
  • the present invention is concerned with a heat-exchanger in which the heat-conducting walls are readily available for replacement and/or cleansing of deposits.
  • a heat-exchanger comprises a set of parallel, spaced-­apart heat-conducting plates defining between them a set of fluid flow channels, a frame member surrounding and engaging the entire peripheries of each of the plates, first inlet passages through the frame member opening into alternate flow channels through which a fluid may be introduced into the alternate flow channels, first outlet passages through the frame member opening into the alternate flow channels through which the fluid may be discharged from the alternate flow channels, second inlet passages through the frame member opening into intermediate flow channels between and immediately adjacent to the alternate flow channels through which a second fluid may be introduced into the intermediate flow channels and second outlet passages through the frame member opening into the intermediate flow channels through which the second fluid may be discharged characterised in that each plate is readily detachable from its engagement with the frame member and a portion of the frame member is readily removable from the frame member whereby the plates can be readily withdrawn and replaced.
  • the frame member is rectangular in shape and correspondingly rectangular plates are kept parallel and separated from each other by their peripheries being held within grooves formed in the inner surface of the frame member.
  • One side of the rectangular frame member is removable or preferably hinged so that the plates are exposed and can be readily withdrawn from the grooves by hand for cleaning or replacement.
  • the plates are preferably of metal such as aluminium.
  • first inlet passages and the first outlet passages lie on opposite sides of the frame member and the second inlet passages and second outlet passages lie on further opposite sides of the frame member such that the fluid flowing in the alternate flow channels travels at right angles to the second fluid flowing in the intermediate flow channel.
  • one set of the inlet passages are confined to a portion of the frame member near one end of the heat-exchanger and the corresponding set of outlet passages are confined to a portion of the opposite side of the frame member near the other end of the heat-exchanger such that fluid passing through the flow channel corresponding with the sets of inlet and outlet passages travels partly at right angles to the partly parallel with the fluid passing through the other flow channels.
  • the heat-exchanger body 1 is box-like in shape, consisting of a rectangular frame member 2, which in turn consists of a vertical frame 3, a top frame 4, a bottom frame 5, and a door member 6 hinged to frames 3 and 4, and two end members 7,8.
  • Frames 3,4 and 5 have grooves 9, formed on the inside to receive the peripheral edges of plain metal plates 10, (for example, of aluminium) of a series 11 of such plates 10, and hold within the body 1 the series 11 of plates 10, in parallel spaced relationship, so forming channels 12, between the plates 10, through which fluids can flow as explained below.
  • the door member 6, has rubber strips 13, mounted in such a position as to make contact, on closing, with the exposed edges of the plates 10, so as to ensure that each plate 10 is firmly engaged within the body 1 so that each channel 12 is sealed from each other channel 12.
  • inlet passages 14, pass through the frame 4 into each alternate channel 12 (designated as 12A) and outlet passages 15, pass from each channel 12A through the frame 5.
  • inlet passages 16 pass through the frame 3 into channels 12 (designated as 12B) which are between the immediately adjacent to the channels 12A, and outlet passages 17, are formed in the door member 6, which open into channels 12B when the door is closed.
  • hot fluid for example hot exhaust air from an industrial plant
  • a second fluid passes into the channels 12B through the inlet passages 16, and out of the outlet passages 17, in a direction at right angles to the direction of the fluid in the channels 12A.
  • the second fluid (for example, fresh air being drawn into an industrial plant) is at a lower temperature than the fluid flowing in the channels 12A and it is heated by heat transferred from the fluid in the channels 12A through the plates 10, into the channels 12B.
  • the deposit of any unwanted material on the plates 10 from the hot fluid is discouraged by the smooth surface of the plates and the "washing down" action of the fluid passing vertically downwards through the channels 12A.
  • FIG 2 there is illustrated an alternative construction for achieving a substantially counter-current flow of the fluid and second fluid.
  • the heat-exchanger 18 of Figure 2 is of similar construction to the heat-exchanger 1 of Figure 1, except that in the frame 3 the inlet passages 16 are confined to a bottom portion of frame 3 while the outlet passages 17 are confined to a top portion of door member 6.
  • access to the channels 12A and 12B is made through the inlet passages 14, 16 and outlet through outlet passages 15, 17, by way of simple manifolds 19, 20, 21, and 22.
  • the direction of the fluid through the channels 12A is vertically downwards while the second fluid which passes through the channels 12B is partly horizontal but substantially vertically upwards (as shown by the line 23) thus providing the optimum conditions for an efficient heat-exchange through the plates 10.
  • the fluid and second fluid may be a liquid, a vapour or a gas.
  • the heat-exchanger in accordance with the invention is particularly useful in taking heat from exhaust gases leaving a stenter used for the orientation of plastic films and transfering the heat to fresh gases entering the stenter which are to be used for heat treatment of the films. Waste materials carried by the exhaust gases which condense on the plates 10 can readily be removed, from time to time, by sliding out the plates 10 and either cleaning immediately or replacing by clean plates 10.
  • two heat exchangers is parallel may be installed so that one can be operating while the other is being cleaned.
  • the plates 10 are preferably mounted within grooves formed in the frame member 2, other mountings, such as rubber or plastic tracks may be used providing that the plates 10 are readily removable and replaceable.
  • the heat-exchanger described above may be used for extracting heat from exhaust gases leaving a stenter used for the orientation of plastic film and transferring the extracted heat to fresh gases entering the stenter which are to be used for heat treatment of the film which is to be orientated.
