Patent attributes
A cooling system, for cooling a plurality of server boards, includes at least one main two-phase fluid circuit, with a descending pipe, an ascending pipe, a loop bottom connector and an upper portion thermally coupled with at least one heat rendering exchanger. The cooling system also includes at least one evaporator coupled to a hot source to be cooled down in the server boards, a plurality of local circuits respectively serving one of the server boards and operating in bypass with respect to the main circuit. Each local circuit includes, on the one hand, a first branch, forming a feed-in on the descending pipe and, on the other hand, a second branch forming a fluid return in the ascending pipe of the main circuit, as well as an auxiliary circuit internal to the server board connected to one or several evaporator(s).
