Patent ID: 8780559

Claim:
An electrical device comprising: a housing comprising a housing inner surface that defines a cavity; a heat sink coupled to said housing and oriented along a first plane; at least one electrical component positioned within said housing cavity, said electrical component oriented along a second plane that is different than the first plane; and a heat exchange assembly coupled to said electrical component and said heat sink for adjusting a temperature of said electrical component, said heat exchange assembly comprising an evaporator section, a condenser section, and a transport section extending between said evaporator section and said condenser section for channeling a gaseous fluid of a working fluid between said evaporator section and said condenser section and for channeling a liquid fluid of the working fluid between said condenser section and said evaporator section, said heat exchange assembly is configured to bend along at least one bending axis oriented with respect to said transport section, wherein the heat exchange assembly further comprises: at least one sidewall having a sidewall inner surface; a plurality of fluid channels defined within said sidewall inner surface to channel the liquid fluid from said condenser section to said evaporator section; and at least one vapor channel defined within said sidewall inner surface to channel the gaseous fluid from said evaporator section to said condenser section; wherein said at least one vapor channel comprises a first side and a second side, said first side extends between a base end and an upper end and said second side extends between said base end and an adjacent upper end, said upper end and said adjacent upper end located on said sidewall inner surface, said upper end and said adjacent upper end are axially spaced along a transverse axis such that said at least one vapor channel comprises a width of each vapor channel measured between said upper end and said adjacent upper end and extends across at least one of the fluid channels, and wherein each vapor channel and each fluid channel extend continuously only along a longitudinal axis from said evaporator section to said condenser section, and wherein the plurality of fluid channels is on only one side of the at least one vapor channel.
