Definitions

  • My invention relates to heat exchangers, and particularly to rotary heat exchangers for extracting heat from a heated fluid column and transferring it to a cooler fluid col- 5 umn.
  • One application of the invention is in extracting heat from hot waste gases, and transferring it to a column of air, although it is to be understood that it is applicable to numerous other uses.
  • I provide a rotary heat exchanger which divides the columns of fluid travelling it into thin streams. Each stream passes through the heat exchanger without distortion, in a direction substantially parallel to the axis of its conduit. By this construction, the pressure drop across the heat exchanger does not difler materially from that in adjacent sections of the fluid conduit.
  • the heat exchanger is constituted by a plurality of continuously rotating spaced disks or plates that project into the fluid conduits, between which the heat exchange takes place. All portions of the plates are simultaneously undergoing a change in thermal condition.
  • the single figure of the accompanying drawing is a longitudinal sectional view through the casing of heating ducts with a heat exchanger embodying my invention disposed therein.
  • a plurality of heat exchangers 2 each comprising a plurality of spaced disks mounted on a shaft 3 are disposed in a central heating duct 4 for transmitting fluid such as hot air.
  • the heat exchangers 2 project through partition walls 5 defining the inner conduit, and inte outer 'ducts 6 in which a fluid is moving in opposite directions to that in the duct 4.
  • the heat exchangers 2 are rotated they become heated in the duct 4 and as they move into the ducts 6 they transfer the stored thermal energy to the fluid in the ducts 6.
  • the heat exchangers2 are preferably rotated so that the hottest sections of ings 8 through which the disks of the heat I exchangers 2 extend.
  • the bars 7 are secured.
  • baflies 10 are mounted near the overlapping sections of the heat exchangers. The presence of the baffles 10 insures that fluid traversing the heat exchangers must follow a path having a sufiicient length to insure an efiicient heat trans- By having the heat exchangers in overlapping relation at their edges, a material reduction in the overall dimensions of the ducts 4 and 6 is obtained.
  • the invention is particularly applicable to fire boxes, chimneys, the exhaust from heat treating devices and the like, where it is desired to utilize the escaping heat for heating another fluid such as air.
  • outer fluid conduits disposed along the edges of the inner conduit, and heat exchangin mechanism operative between the inner an outer conduits comprising a plurality of disks arranged in groups and rotating in the inner and outer conduits, the individual disks of the difl'erent groups being in overlapping relation, whereby the disks of one group space the'disks of another group.
