An arrayed fin cooling system for removing waste heat from a component is disclosed. The arrayed fin cooling system includes plurality of discrete cooling fins that act as individual heat sinks. The cooling fins are arranged in a radial array so that the cooling fins diverge from one another to define an air path between adjacent cooling fins. Each cooling fin includes a base that is adapted to connect with a surface of the component to be cooled. Waste heat is transferred from the component to the cooling fin via the base. The cooling fins are surrounded at an outer edge by a radial shield that channels an air flow over the cooling fins to maximize the amount of air that passes over the cooling fins. The cooling fins can be manufactured at a low cost using processes such as stamping and forging.
