Abstract: This patent document describes techniques are related to an apparatus for an electronics box for an in-flight entertainment system. The electronics box comprises: a sealed enclosure including electronic components for the in-flight entertainment system disposed in a commercial passenger vehicle; and a cooling structure disposed on a surface of the sealed enclosure and includes: a fan introducing air from outside into the cooling structure, the air creating an air passage that is external to the sealed enclosure and extending along the surface of the sealed enclosure; one or more heat dissipation elements disposed in the air passage and configured to dissipate heat generated by the electronic components; and a duct cover covering the fan and the one or more heat dissipation elements and having an air inlet through which the air enters into the cooling structure.

Abstract: This patent document describes techniques are related to an apparatus for an electronics box for an in-flight entertainment system. The electronics box comprises: a first module including a first group of electronic components for the in-flight entertainment system and having a housing accommodating a first board on which the first group of electronic components are disposed; and a second module detachably placed over the first module and having a second board on which a second group of electronic components for the in-flight entertainment system are disposed, the second board covered by a frame that forms a sealed enclosure with the housing, and wherein the first group of electronic components and the second group of electronic components are configured to provide power or data to at least one of the in-flight entertainment system that is located in a commercial passenger vehicle.
