Patent ID: 8024942

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 along the heat transfer surface of the condenser such that the flow of the first external fluid along the heat transfer surface 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 has a substantially tubular shape having a first end and a second end, wherein the flow of the first external fluid along the heat transfer surface is in a direction from the first end of the condenser to the second end of the condenser, wherein the first external fluid flows along the heat transfer surface without having a component of flow of the first external fluid perpendicular to the heat transfer surface.
