Abstract
A heat exchanger for cooling a heat generating device is provided that includes a plurality of plates each defining at least one through-bore. The plates are laminated together to form a stack so that a plurality of enclosed chambers are formed by an alignment of a first portion of the through-bores within the block, and a plurality of passageways are formed by an alignment of a second portion of the through-bores within the stack such that at least one of the passageways is arranged in fluid communication with at least two of the chambers. A baffle-plate is disposed within a portion of the stack so as to form a chamber boundary and thereby to define a circuitous fluid flow path between the chambers through the at least one passageway. A fluid entrance port is defined in a first outer one of the plates and arranged in fluid communication with one of the chambers, and a fluid exit port is also defined in a second outer one of the plates and arranged in fluid communication with another one of the chambers.
