Patent ID: 7987900

Claim:
A heat exchange chamber comprising: an inlet for receiving a heat exchange medium flowing in a first flow direction in an initial line of flow; a plurality of walls defining a chamber interior which is in fluid communication with the inlet; a medium directing member, having an inclined surface facing the inlet, disposed at least partially within the chamber interior near the inlet to divert the medium from the initial line of flow to a second flow direction which is substantially perpendicular to the first flow direction so that the medium disperses within the chamber interior; and an outlet in fluid communication with the chamber interior for outputting the medium, the outlet having an opening rewardly facing the first flow direction, wherein the chamber is configured to cause the medium, subsequently to flowing in the first flow direction, to flow within the chamber interior in first and second generally semi-circular flow paths, each of which travels at least partially around a respective line segment extending from the inlet in the first flow direction and lies in a plane substantially perpendicular to the first flow direction, the first and second flow paths originating from a same region within the chamber interior and flowing in opposing generally semi-circular routes at least partially around the respective line segment.
