Abstract:
A cold plate assembly includes an inlet manifold layer, a target heat transfer layer, a second-pass heat transfer layer, and an outlet manifold layer. The inlet manifold layer includes a coolant fluid outlet and an inlet channel. The inlet channel includes a plurality of fluid inlet holes fluidly coupled to a plurality of impingement jet nozzles. The target heat transfer layer includes a plurality of target heat transfer cells having a plurality of target heat transfer layer microchannels extending in a radial direction from a central impingement region. The second-pass heat transfer layer includes a plurality of second-pass heat transfer cells having a plurality of second-pass heat transfer layer microchannels extending in a radial direction toward a central fluid outlet region, and one or more transition channels. The impingement jet nozzles are positioned through the central fluid outlet region. The outlet manifold layer includes an outlet channel having a plurality of fluid outlet holes.
