Abstract: An example axial pump for delivering liquid coolant to cool an electronic device comprises a conduit defining a flow path from an inlet of the conduit to an outlet of the conduit and an impeller in the conduit. The impeller is rotatable about an axis of rotation parallel to the flow path. The pump also has a motor stator configured to drive rotation of the impeller body about the axis of rotation. In addition, the pump comprises an adjustment mechanism coupling the impeller to the conduit. The adjustment mechanism is actuatable to cause translation of the impeller relative to the conduit. This may allow for adjustment of a clearance between a blade tip of a blade of the impeller and a wall of the conduit.

Abstract: A heat removal apparatus may comprise a vapor chamber device and a cover coupled to the vapor chamber device. The vapor chamber device comprises a base, a folded fin structure coupled to the base, with the base and folded fin structure defining a vapor chamber containing a wick and a working fluid. The cover and the vapor chamber device define a liquid chamber configured to receive liquid coolant. The folded fin structure comprises a plurality of folded fins defining a first plurality of grooves on a first side of the folded fin structure and defining a second plurality of grooves on a second side of the folded fin structure. The first plurality of grooves are part of the vapor chamber. The second plurality of grooves are part of the liquid chamber.
