Abstract
A high intensity cooling device is disclosed. The cooling device includes first and second superimposed laminations, with each of the laminations including a cavity having a spiral fin defining a spiral flow chamber. One of the flow chambers directs a coolant medium along an inwardly spiraling flow path, while the other of the flow chambers directs the coolant medium along an outwardly spiraling flow path, with the flow chambers being in flow communication. A coolant inlet communicates the coolant medium to the first flow chamber, and a coolant outlet communicates the coolant medium away from the second flow chamber. Thus, the coolant medium may be routed along a spiral flow path through each of the laminations.
