Abstract:
A modular cooling system for an electronics enclosure mounting a plurality of heat generating electronic components; the cooling system comprising:a plurality of cooling modules selectively mountable into the electronics enclosure, each of the cooling modules comprising an evaporative cold plate including an evaporative flow path to direct a working fluid through the cold plate in heat exchange relation with electronic components associated with the cold plate to reject heat from the electronic components to the working fluid, a condenser including a condensing flow path to direct the working fluid through the condenser in heat exchange relation with a cooling liquid to reject heat from the working fluid to the cooling liquid, a cooling liquid inlet connection, a cooling liquid outlet connection, and a cooling liquid flow path to direct the cooling liquid through the condenser from the cooling liquid inlet to the cooling liquid outlet in heat exchange relation with the working fluid in the condensing flow path to reject heat from the working fluid to the cooling liquid, a vapor conduit connecting the evaporative cold plate to the condenser to direct vapor phase working fluid from the evaporative flow path to the condensing flow path, and a liquid conduit connecting the condenser to the evaporative cold plate to direct liquid phase working fluid from the condensing flow path to the evaporative flow path; a cooling liquid supply manifold including a plurality of cooling liquid supply connections, each of the supply connections configured to connect with the cooling liquid inlet connection of one of said cooling modules to supply cooling liquid thereto; and a cooling liquid return manifold including a plurality of cooling liquid return connections, each of the return connections configured to connect with the cooling liquid outlet connection of one of said cooling modules to receive cooling liquid therefrom.
