Abstract:
1. A system, comprising: a first and second electronic circuit board respectively disposed to define a narrow gap there between; at least one nozzle configured to spray an atomized liquid such that a flow of the atomized liquid and a vapor is induced through the narrow gap; a heat exchanger configured to condense some of the vapor to liquid, thus defining a condensate; a capillary device and a liquid conduit that is slidably engaged with a support member, wherein the capillary device is configured to route at least some of the condensate into the liquid conduit and wherein the capillary device comprises multiple wick structures connected by a liquid bridge to separate liquid and vapor from the flow exiting the narrow gap, the liquid bridge being configured to route condensed vapor away from at least one of the first and second electronic circuit boards and toward the liquid conduit; and a housing configured to guide a circulation of at least some of the vapor flowing out of the narrow gap away from the heat exchanger and into proximity with the at least one nozzle, wherein the heat exchanger is mechanically coupled to the housing to provide a substantially vapor tight seal with the housing.
