Abstract:
1. Apparatus for transferring heat energy to and from a body surface respectively from and to heat transfer fluid that is introduced into and removed from a space bounded by the body surface for heat transfer contact with the body surface, the apparatus comprising: a body providing a body surface of cylindrical transverse cross section that is to be contacted by heat transfer fluid; a plurality of hear exchanger elements within a casing having a shape that provides between each of said plurality of heat exchanger elements and the body surface a flow gap for flow of heat transfer fluid between the periphery of the elements and the body surface in heat transfer contact with the body surface, each of the connecting tubes, including a first set of heat exchanger elements connected by a first connecting tube and a second set of heat exchanger element connected by a second connecting tube being less than the longitudinal length of each of the heat exchanger elements; a first plenum at one end of the flow gap from which heat transfer fluid can flow through the flow gap, or into which heat transfer fluid can flow from the flow gap; a second plenum at the other end of the flow gap respectively into which heat transfer fluid can flow from the flow gap, or from which heat transfer fluid can flow into the flow gap.
