Patent ID: 6929058

Claim:
A cold plate with an inlet and an outlet for a fluid comprising: a) a base having a groove having first and second ends, the first end being connected to the inlet and the second end connected to the outlet; b) a plate connected to the base covering the groove; and c) at least one vortex generator located on a surface of the plate and aligning with and extending into the groove of the base, each of the at least one vortex generator having a first pair of unparallel and symmetrical ribs, each of the first pair of unparallel and symmetrical ribs having: i) parallel front and rear surfaces extending perpendicular to the surface of the plate; ii) first, second, and third edges located between the parallel front and rear surfaces, the first edge being connected to the plate; and iii) a sharp portion located between the second and third edges and extending upwardly toward the base, first ends of the first pair of unparallel and symmetrical ribs are positioned a contraction distance apart, and second ends of the first pair of unparallel and symmetrical ribs are positioned a expansion distance apart, the fluid passing between the first pair of unparallel and symmetrical ribs, the contraction distance is smaller than the expansion distance.
