ABSTRACT:
A heat exchanger is provided for dissipating heat from a fluid. The heat exchanger includes a plurality of stacked pairs of plates. Each pair of plates includes a first plate and a second plate. The first plate extends along a first axis and has first and second sides. The first side of the first plate has a generally sinusoidal recess therein that extends along the first axis. The second plate extends along a second axis and has first and second sides. The first side of the second plate has a generally sinusoidal recess therein that extends along the second axis and that is out of phase with the sinusoidal recesses in the first side of the first plate. The first side of the first plate and the first side of the second plate form a mating relationship with each other such that the recess in the first side of the first plate communicates with the recess in the first side of the second plate at a plurality of axially spaced locations.
