Abstract

A side flow cooling device is disclosed. The side flow cooling device includes a heat mass with arms extending therefrom and a mounting surface for connecting the heat mass with a component to be cooled. The heat mass and the arms include a plurality of fins extending outward therefrom and aligned with a vertical axis of the heat mass. The fins have cooling surfaces and a slot between adjacent fins that are aligned with a longitudinal axis of the heat mass. A fan or the like can be connected with a side face of the cooling device to generate an air flow that is substantially along the longitudinal axis. The air flow wets over the cooling surfaces of the fins, on exposed portions of the heat mass, and on exposed portions of the arms to dissipate heat from the heat mass. The heat mass is not covered by the fan and therefore the fins can populate a substantial portion of a surface area of the heat mass thereby increasing the surface area available for cooling.

Dependent claims

A side flow cooling device for dissipating heat from a component, comprising:

a heat mass including a top surface, a mounting surface adapted to thermally connect the heat mass with the component, opposed side surfaces, and opposed end surfaces;
an arm in contact with the heat mass and extending outward of the opposed side surfaces, the arm including a upper surface and a lower surface;
a rib connected with the arm and extending downward of the arm;
a wing connected with the rib and extending outward therefrom, the wing adapted to the connect the side flow cooling device with the component;
a plurality of fins substantially aligned with a vertical axis of the heat mass and connected with the top surface of the heat mass and the upper and lower surfaces of the arm,
each fin including opposed cooling surfaces, a top edge, opposed end edges that define a first side face and a second side face of the side flow cooling device, the fins are spaced apart to define a slot therebetween, and the slot and the opposed cooling surfaces are substantially aligned with a longitudinal axis of the heat mass, and
wherein an air flow entering either of the first or second side faces in a direction substantially along the longitudinal axis passes through the slots and wets over the opposed cooling surfaces and the heat mass to dissipate heat from the heat mass.
