Condenser fin structures facilitating vapor condensation cooling of coolant

摘要

Vapor condensers and cooling apparatuses facilitating vapor condensation cooling of a coolant employed in cooling an electronic device or electronic subsystem. The vapor condenser includes a thermally conductive base structure having an operational orientation when the condenser is facilitating vapor condensate formation, and a plurality of thermally conductive condenser fins extending from the thermally conductive base structure. The plurality of thermally conductive condenser fins have a varying cross-sectional perimeter along at least a portion of their length. The cross-sectional perimeters of the plurality of thermally conductive condenser fins are configured to increase in a direction of condensate travel through the thermally conductive base structure.

1. A cooling apparatus comprising:
a heat exchanger comprising a compartment in fluid communication with a cooling loop; and a vapor condenser disposed within the compartment of the heat exchanger to facilitate vapor condensate formation from vaporized coolant within the compartment, the vapor condenser comprising a thermally conductive base structure having a vertical orientation, and a plurality of condenser fins extending from the thermally conductive base structure into the compartment, the plurality of thermally conductive condenser fins having a varying transverse cross-sectional perimeter along at least a portion of their length, wherein the transverse cross-sectional perimeters of the plurality of thermally conductive condenser fins increase in a direction of condensate travel as the vapor condenser facilitates vapor condensate formation on the plurality of thermally conductive condenser fins within the compartment.
