The cooling device includes an inner side with a plurality of projections for coupling to a corresponding side or portion of the electronic device. The cooling device includes side walls extending about at least a portion of the back portion and from the inner side. The side walls include an inner surface for coupling to sides or portions of the electronic device. The side walls include a plurality of cooling apertures therethrough, and cooling channels recessed in the second inner surface extending from each cooling aperture to at least the back portion. When the cooling device is coupled with the electronic device, the plurality of projections, cooling channels, and portions of the electronic device proximate thereto form a plurality of cooling pathways that extend between the plurality of cooling apertures. ## Claims ### Claim 1 A cooling device for an electronic device, the cooling device comprising: a back portion including a first outer surface and a first inner surface, the first inner surface including a plurality of projections for coupling to a back side of the electronic device when the cooling device is coupled to the electronic device; and side walls extending about at least a portion of the periphery of the back portion and from the first inner surface thereof including a second outer surface and a second inner surface for coupling to side surfaces of the electronic device when the cooling device is coupled to the electronic device, the side walls including a plurality of cooling apertures extending from the second inner surface to the second outer surface and a recessed cooling channel in the second inner surface extending from each cooling aperture at least to the back portion, and wherein when the cooling device is coupled to the electronic device, the plurality of projections, the cooling channels and the back side of the electronic device form a plurality of cooling pathways extending between the plurality of cooling apertures and along at least a portion of the back side of the electronic device. ### Claim 2 (depends on 1) The cooling device of claim 1, wherein a front side of the electronic device includes a display configured to be viewed in a first orientation of the electronic device, and wherein the plurality of cooling apertures include a first cooling aperture positioned above a second cooling aperture in the vertical direction when the cooling device is coupled to the electronic device and the electronic device is oriented in the first orientation. ### Claim 3 (depends on 2) The cooling device of claim 2, wherein the display is configured to be viewed in a second orientation of the electronic device, and wherein the plurality of cooling apertures include a first cooling aperture positioned above a second cooling aperture in the vertical direction when the cooling device is coupled to the electronic device and the electronic device is oriented in either of the first and the second orientations. ### Claim 4 (depends on 1) The cooling device of claim 1, wherein the majority of the first inner surface includes the plurality of projections. ### Claim 5 (depends on 1) The cooling device of claim 1, wherein at least 75 percent of the first inner surface includes the plurality of projections. ### Claim 6 (depends on 1) The cooling device of claim 1, wherein the first inner surface includes within the range of about 40 projections per square inch to about 120 projections per square inch. ### Claim 7 (depends on 1) The cooling device of claim 1, wherein each cooling channel extends on the first inner surface of the back portion proximate to the plurality of projections on the first inner surface. ### Claim 8 (depends on 1) The cooling device of claim 1, wherein the plurality of projections are spaced from each other on the first inner surface, and wherein at least some of the portions of the first inner surface void of the plurality of projections are substantially planar. ### Claim 9 (depends on 1) The cooling device of claim 1, wherein the plurality of projections are dome or conical shaped. ### Claim 10 (depends on 9) The cooling device of claim 9, wherein the projections are each defined by a radius of about 1.3 millimeters. ### Claim 11 (depends on 1) The cooling device of claim 1, wherein the plurality of projections are arranged in an evenly spaced grid pattern. ### Claim 12 (depends on 1) The cooling device of claim 1, wherein the back portion and the side walls are of one-piece construction. ### Claim 13 (depends on 1) The cooling device of claim 1, wherein the back portion and the side walls are formed of food-grade silicone. ### Claim 14 (depends on 1) The cooling device of claim 1, wherein the electronic device is a portable hand-held electronic device.
