Abstract: An impingement cooling device including a distributor plate, a manifold, and a heat spreader. The distributor plate includes a first side, a second side opposite the first side, a plurality of injection ports extending through the distributor plate from the first side to the second side, and a plurality of extraction ports extending through the distributor plate from the first side to the second side. The manifold is coupled to the distributor plate and includes a partition wall separating the plurality of injection ports and the plurality of extraction ports on the first side. The heat spreader at least partially covers an object to be cooled and includes a top surface configured to oppose the second side of the distributor plate. The heat spreader further includes a surface feature on the top surface configured to increase heat transfer therefrom.

Abstract: An apparatus having first, second, and third chambers and a plurality of receiving channels is disclosed. The first chamber includes a device surface to be cooled. The second chamber has a first surface positioned opposite to the device surface to be cooled, the first surface including a plurality of jet openings adapted to spray a coolant on the device surface when the second chamber is pressured with the coolant. The third chamber is adapted to receive coolant that left the first chamber. Each of the receiving channels has a first end in the first chamber and a second end in the third chamber. Each of the receiving channels is adjacent to a corresponding one of the jet openings and is positioned to remove coolant dispersed into the first chamber by that jet opening.
