Patent ID: 8347952

Claim:
A cooling mechanism comprising: a first heat exchanger including a forced-fluid driver, wherein the first heat exchanger is configured to pump heat from inside an enclosed area to outside of the enclosed area; a first fluid-flow port configured to accommodate a first fluid flow into the enclosed area; and a second fluid-flow port configured to accommodate a second fluid flow from the enclosed area, wherein the first fluid-flow port and the second fluid-flow port are approximately coplanar, and wherein both of the first fluid-flow port and the second fluid-flow port, are tapered to have an associated cross-sectional area which is smaller at an edge of the respective fluid-flow port which is proximate to the outside of the enclosed area than at an edge of the respective fluid-flow port which is proximate to the inside of the enclosed area, wherein the tapering of the first fluid-flow port and the second fluid-flow port reduces recirculation of heated fluid in the enclosed area.
