Abstract:
A cooling device for dissipating heat from a component, comprising:a heat mass including a top surface and a mounting surface adapted to thermally connect the heat mass with the component; a plurality of fins connected with the top surface and substantially aligned with a vertical axis of the heat mass, each fin including opposed side surfaces, a top edge, a leading edge, and a trailing edge, the fins are spaced apart from one another to define a plurality of slots therebetween that are substantially aligned with a longitudinal axis of the heat mass; and an air shower including an air inlet extending into the air shower and terminating at a closed end to define an air impingement chamber therein, an injector face, and a plurality of disrupter orifices extending from the air impingement chamber to the injector face, the injector face is positioned adjacent to the top edges of the fins so that disrupter orifices are positioned over the slots; and wherein a second air flow enters the air impingement chamber through the air inlet and exits the air impingement chamber through the disrupter orifices, the second air flow enters the slots and impinges on a first air flow flowing through the slots, the second air flow induces turbulence in the first air flow and the turbulence is operative to disrupt a thermal boundary layer in the first air flow thereby increasing a rate of heat transfer from the fins and the heat mass to the first air flow.
