Abstract
An apparatus includes a chimney cooler having a housing. The housing includes a base and sidewalls. The base is configured to support one or more heat-generating components. The sidewalls extend from the base, and each sidewall includes multiple channels. Each channel defines a serpentine flow path configured to receive a fluid coolant. The sidewalls may be lofted away from the heat-generating component(s) as the sidewalls extend from the base. An inlet for each channel may be contoured to promote inertial flow of the fluid coolant into the serpentine flow path. An outlet for each channel may be contoured to promote inertial flow of the fluid coolant exiting the serpentine flow path. Channels at and adjacent to primary objective surfaces of the housing may share a common inlet. The channels at the primary objective surfaces of the housing may have larger outlets relative to the channels adjacent to the primary objective surfaces of the housing.
