Patent number: 8665591Abstract: A system for an electronic device includes a housing having one or more walls that define an internal region. An outlet port is fluidically coupled to the internal region of the housing, which allows emission of a fluid from the internal region of the housing as a first flow at a first temperature. A merging element, fluidically coupled to the outlet port, merges the first flow with a second flow, which has a second temperature that is less than the first temperature.Type: GrantFiled: December 21, 2010Date of Patent: March 4, 2014Assignee: General Electric CompanyInventors: Richard Bourgeois, Kristopher Frutschy, Mohamed Sakami, William Waters, Mao Leng
