1. A heat exchanger comprising:
- (a) a hollow drum through which a heating or heated medium can be circulated,(b) means rotably mounting said hollow drum within an outer casing, inlet means for introducing fluid into said outer casing,(c) an outlet means for discharging said fluid after being heated from said outer casing,(d) a plurality of hollow and disc-like projections mounted on the outer peripheral surface of said hollow drum,(e) first partition means dividing the interior of said hollow drum into supply and discharge passages,(f) a supply port for each projection at said peripheral wall of said hollow drum communicating with said supply passage and a discharge port for each projection at said peripheral wall of said hollow drum communicating with said discharge passage, whereby said heating medium supply and discharge passages each communicate with the interior of hollow portions of said projections,(g) second partition means within each of said hollow disc-like projections between a supply port and a discharge port thereof for directing fluid around the interior of said projection from said supply port to said discharge port, said second partition means comprising a solid radial wall disposed between said supply port and said discharge port, said solid radial wall defining a C-shaped fluid passage in said disc-like partition and(h) a plurality of perforated radial walls disposed in said C-shaped fluid passage in a circumferentially spaced-apart manner, said each perforated radial wall having a multiplicity of small communicating apertures through which said fluid passes and circumferential wall disposed within said C-shaped fluid passage dividing said flow passage into inner and outer flow passages.

Abstract
This invention provides a structure of a heat exchanger in which a hollow drum, into which a heating or heated medium can be charged, is rotatably housed in a cylindrical outer casing, a large number of hollow projections are formed on the outer peripheral surface of the hollow drum, heating medium supply and discharge passages defined by a partition are provided within the hollow drum, and these heating medium supply and discharge passages communicate with hollow portions of the projections.
