Patent ID: 7934540

Claim:
An integrated liquid cooling unit for cooling an electronic device comprising: a liquid pump having an inlet and an outlet for circulating a coolant, a tube extending through a heat exchange leg defining an entrance and a return leg defining an exit with said legs being spaced, said tube having a flat cross-section having sides defining a tube width, said flat cross-section presenting an interior surface, an outside wall and an inside wall in each leg interconnected by said sides being rounded, said tube extending in a U-shape between said entrance and said exit, and including at least one flow interrupter disposed on said heat exchange leg of said tube and defining at least one rib extending across said interior surface and defining a rectangular recess extending across said inside wall of said heat exchange leg between said rounded sides and defining an un-recessed section of said heat exchange leg of said tube, and an adapter being an integral component rigidly connecting said liquid pump to said tube to prevent relative movement between said liquid pump and said tube and defining an input manifold establishing fluid communication between said outlet of said liquid pump and said heat exchange leg of said tube and an output manifold establishing fluid communication between said inlet of said liquid pump and said return leg of said tube.
