Abstract

An electronic component enclosure includes a plurality of wall structures defining outer walls of the enclosure. Each wall structure has an internal fluid channel for circulation of cooling fluid. The enclosure further includes at least one partition structure disposed within the outer walls and having an internal fluid channel in sealed fluid communication with the internal fluid channel of at least one of the plurality of wall structures. The internal fluid channel of at least one of the plurality of wall structures and the internal fluid channel of the at least one partition structure defines a continuous fluid circulation path between a fluid inflow port and a fluid outflow port.
