Abstract
A recuperative or restorative spiral heat exchanger with separating walls spirally extending between fluid streams of medium having an exploitable temperature gradient. Each two adjacent separating walls enclose between themselves a flow duct for one of the two streams of medium and the spiral space between two flow ducts forms the path of flow for the other stream of medium. The spiral is provided in the form of a multiple or multi-channel spiral by arranging a plurality of flow ducts. In particular, the spiral heat exchanger consists of two multiple spirals with opposed directions of current.
Claims3
A recuperative spiral heat exchanger, comprising:
- two interconected multi-channel spirals having opposed directions of spirals and composed of a multiplicity of spirally-extending, spaced-apart separating walls, each adjacent pair of which define a flow duct therebetween used in an alternate fashion for one of two oppositely flowing streams of medium, said two spirals together forming substantially S-shaped flow ducts lying substantially in the same plane,
- a closed housing in which said two spirals are arranged, and
- inflow and outflow openings for said flow ducts, said inflow openings being disposed in said housing approximately at the center of one of said spirals and said outflow openings being disposed in said housing approximately at the center of said other spiral.
