A housing 10 of a vehicular camera assembly cools a heat-generating element of the camera assembly. The housing has a thermally conductive hollow body with integral circular and rectangular segments. Sets of thermally conductive ribs 102,102’,103 are on an outer surface of at least one of the segments generally adjacent the heat-generating element. The sets of ribs alternate their respective orientation, lengths and depths defining sets of air guiding channels 104 of alternating lengths and depths from one segment to another. The circular segment of housing may have a first set of thermally conductive ribs protruding radially, defining a first set of air guiding channels of non-uniform cross-sections. The rectangular segment of housing may have a second set of thermally conductive ribs protruding axially, defining a second set of air guiding channels of non-uniform cross-section. The circular segment may have the first set of air guiding channels and the rectangular segment may have the second set of air guiding channels with none of the orientation, depth or length of the first set of air guiding channels being the same as those of the second set of air guiding channels. A process of obtaining this housing includes forging the described features.
