Patent ID: 7558063

Claim:
A server with a flexible cooling scheme, comprising: a case having an inside and an outside; a first fan positioned inside the case and configured to draw gas from a first area inside the case and force the gas past a first area to be cooled; a first opening in the case configured to allow gas from outside the case to enter the first area; when the server is in a first cooling configuration the first fan is configured to force the gas past the first area to be cooled and out to the outside of the case through a second opening in the case; when the server is in a second cooling configuration, the server further comprises: a heat exchanger located in the first area and configured to seal the first opening in the case thereby preventing outside gas from entering the first area; a sealing device configured to seal the second opening thereby redirecting the first fan to force the gas past the first area to be cooled and back into the first area, thereby re-circulating the gas inside the case.
