Abstract
A heat exchanger (10) for indirectly heating, drying and cooling materials comprises a hollow rotor (40) having an inlet (46) of heating and cooling medium and an outlet (47) of the medium or its condensate, a casing mounted on the hollow rotor, a plurality of disc-shaped base boards (20), a plurality of annular ducts (21, 23; 22, 24) projected from both side surfaces (11, 12) of the base boards (20), the duct forming a passage communicating with the inlet (46) and the outlet (47), arranged so as to be partly superposed sequentially on both front and back surfaces (11, 12) of the base board (20) from the inner peripheral edges to the outer peripheral edges of the base boards (20) in such a manner that partition plates for shielding the ducts (21, 23; 22, 24) being provided in the superposed positions.
Claims18
A heat exchanger comprising a hollow rotor having an inlet of heating and cooling medium and an outlet of the medium or its condensate, a casing mounted on the hollow rotor,
- a plurality of disc-shaped base boards, a plurality of annular ducts projected from both side surfaces of the base boards,
- said duct forming a passage communicating with the inlet and the outlet, arranged so as to be partly superposed sequentially on both front and back surfaces of the base board from the inner peripheral edges to the outer peripheral edges of the base boards in such a manner that partition plates for shielding the ducts being provided in the superposed positions in the ducts and inserting holes communicating between the front side and back side ducts being perforated at the base boards through the partition plates.
A heat exchanger comprising
- a hollow rotor having an inlet for a heat exchange medium and an outlet for the heat exchange medium;
- at least one disc-shaped base board mounted on said rotor;
- a plurality of concentric annular ducts mounted on opposite sides of said base board in partially overlapping relation;
- at least one pair of partitions disposed in each duct in circumferentially spaced relation to divide said duct into a primary chamber and a secondary chamber;
- an inlet opening in said rotor communicating said rotor inlet with said primary chamber of an innermost duct to deliver the heat exchange medium thereto;
- an outlet opening in said rotor communicating said secondary chamber of said innermost duct with said rotor outlet to exhaust heat exchange medium therethrough;
- and
- a plurality of openings in said base board, each said opening communicating one chamber of one duct with one chamber of an overlapping duct to define a flow path of the heat exchange medium from said primary chamber of said innermost duct sequentially through said primary chambers of the remaining ducts and then through said secondary chambers of said remaining ducts to said secondary chamber of said innermost duct.
A base board for a heat exchanger comprising
- a disc-shaped base board;
- a plurality of concentric annular ducts mounted in alternating manner on opposite sides of said base board and in partially overlapping relation;
- at least one pair of partitions in each duct to divide said duct into a primary chamber and a second chamber;
- and
- a plurality of openings in said base board, each said opening communicating one chamber of one duct with one chamber of an overlapping duct to define a flow path for a heat exchange medium sequentially through said primary chambers of ducts and then sequentially through said second chambers of said ducts.
