Spiral heat exchanger

摘要

The invention relates to a spiral heat exchanger including a spiral body formed by at least one spiral sheet wound to form a first spiral-shaped flow channel for a first medium, and a second spiral-shaped flow channel for a second medium. The spiral body is enclosed by a substantially cylindrical shell with connecting elements communicating with the first flow channel and the second flow channel. The shell includes at least two shell parts, and the spiral body is provided with at least one fixedly attached flange on its outer peripheral surface, whereupon the at least two shell parts are removably attached.

主权项

1. A system of spiral heat exchangers arranged in series or in parallel, wherein the spiral heat exchangers comprise a spiral body in which at least one spiral sheet is configured to define at least a first spiral-shaped flow channel for a first medium and a second spiral-shaped flow channel for a second medium, wherein the spiral body possesses opposite ends and an outer peripheral surface, wherein the spiral body is enclosed by a shell provided with connecting elements communicating with the first flow channel and the second flow channel, the shell comprising at least two shell parts, and the spiral body being provided with at least one flange possessing an inner periphery that is fixedly attached onto the outer peripheral surface of the spiral body at an intermediate location between the opposite ends of the spiral body so that portions of the spiral body are positioned on opposite sides of the flange, the at least two shell parts being releasably coupled to each other, and the spiral heat exchangers being coaxially arranged and connected to one another.
