COOLING DEVICE WITH LIQUID FOR ELECTRONIC CARDS, IN PARTICULAR FOR HIGH PERFORMANCE PROCESSING UNITS

摘要

Cooling device with liquid for electronic cards (16), in particular for high- performance processing units, comprising at least a hydraulic circuit (13) in which a heat-carrying fluid flows in order to extract the heat produced by electronic components (18) and/or hot spots (20) present on an associated electronic card (16). The device comprises a cooling plate (12) mechanically coupled to the electronic card (16) so as to be inserted in a containing rack (30) of the processing unit. The plate (12) has a heat extraction surface (24) facing and partly in contact, or at least in close proximity, with the electronic components (18) and/or the hot spots (20). The hydraulic circuit (13) is made in the thickness of the plate (12) and has a geometric grid development, along which a plurality of hydraulic sub-circuits (13a) are disposed and switching means (42) to define desired paths. The plate (12) has sliding guide means (15) able to cooperate with corresponding alignment means (31) of the containing rack (30),
