<p>There is referred to an arrangement of a heat exchanger construction (10), comprising two plates having a given breadth and with a substantially constant mutual spacing which are wound in the form of a spiral about an axis (22) to form two separate helical fluid loops each with central axial openings, which openings each define inlets or outlets to the two fluid loops. The arrangement is characterised by two heat exchanger units (34, 32) having mutual mirror-image oriented windings about respective axes, and the two outer plates (40, 42) in the one unit (32) are connected to the two equivalent outer plates in the other unit (34), and in a contact line or surface (36, 44) between the helical units there is a fluid-tight sealing between the units. There are also referred to a method and an apparatus for the production of a heat exchanger construction.</p> |
