Patent number: 8809697Abstract: An electronics enclosure is disclosed that provides passive cooling of electronic components while reducing electromagnetic interference (EMI) emissions. The electronics enclosure includes an electronics assembly with at least one electronic component and a heat sink coupled to the electronics assembly. The heat sink has a base portion configured to thermally couple to the at least one electronic component when the heat sink is coupled to the electronic assembly. The electronics enclosure also includes a conductive enclosure forming an enclosed volume around the electronics assembly. The enclosure has a first opening configured to fit around the heat sink and at least one second opening. All non-conductive passages from the volume to the external environment have at least one cross-sectional opening having a continuous conductive perimeter with a maximum linear length within the opening of less than one quarter wavelength of a determined maximum shielding frequency.Type: GrantFiled: May 5, 2011Date of Patent: August 19, 2014Assignee: CareFusion 303, Inc.Inventors: David H.
