Patent ID: 7318325

Claim:
A condenser, comprising: a heat transfer surface, wherein the condenser acts as a heat exchanger so that heat is removed from a compressed refrigerant by a first external fluid in thermal contact with the heat transfer surface of the condenser; and a means for flowing the first external fluid across the heat transfer surface of the condenser, wherein the flow of the first external fluid is substantially parallel with the heat transfer surface of the condenser, wherein the flow of the compressed refrigerant is substantially perpendicular to the flow of the first external fluid, wherein the condenser comprises a second surface, wherein the second surface is substantially parallel to the heat transfer surface, wherein the condenser has a substantially tubular shape having a first end and a second end, wherein the heat transfer surface is on the exterior side of the substantially tubular shaped condenser and the second surface is on the interior side of the substantially tubular shaped condenser, and wherein a volume is formed by the second surface of the substantially tubular shaped condenser.
