Apparatus for transfer of heat energy between a body surface and heat transfer fluid
First Claim
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.

Abstract
In apparatus for heat exchange to and from a body surface using a heat transfer liquid a heat exchanger comprises a plurality of elements within a casing connected axially against one another with spacer tube elements. Each element has its periphery spaced from the body surface to provide a flow gap for heat transfer fluid in heat exchange contact with the surface. The element have plenums separating each from one another forming connecting flow spaces for the heat transfer liquid between the heat transfer flow gap and inlet and outlet passages passing through the body. A preferred apparatus is a cylindrical rotor within a cylindrical stator with an annular processing space between them, the rotor containing a stack of heat exchange elements of the respective shape permitting high heat flux rates and uniform temperature distribution over the total rotor heat transfer surface.
