Abstract (en)
[origin: WO03022415A2] In methods and apparatus for heat exchange to and from a body surface using a heat transfer fluid the fluid is impinged on the surface from a plurality of delivery inlets in the form of a corresponding plurality of spaced delivery streams and is immediately removed from the plenum upon rebounding from the surface through a plurality of spaced removal outlets distributed among the delivery streams, thus establishing corresponding very short uninterrupted flow paths between each inlet and its removal outlet/s. Preferably, the fluid stream velocity is sufficient for it to penetrate and disrupt a fluid boundary layer on the body surface. Each delivery inlet may have its outlet to the surface spaced from 0.001cm to 0.2cm (0.0004in to 0.08in) from that surface. Each delivery inlet may produce a jet impinging the surface of from 0.3cm to 1.5cm (0,12in to 0.6in) diameter. The delivery streams may impinge a flat body surface from a right angle to an acute angle, while when the body surface is curved the delivery streams may impinge from a right angle to one that is tangential thereto. A particular apparatus with which the heat exchanger may be used has a cylindrical rotor rotating within a cylindrical stator so that the body surface is cylindrical; the rotor diameter may be from 0.1cm to 500cm (0.04in to 200ins).
