Arrayed fin cooler

An arrayed fin cooling system for removing heat from a component, comprising:

• a plurality of discrete cooling fins, wherein each discrete cooling fin includes an inner edge, an outer edge, opposed cooling surfaces that are spaced apart by a distance that decreases from the outer edge to the inner edge, a leading edge, and a trailing edge,
• the cooling fins are connected with one another along a portion of their cooling surfaces with their inner edges positioned proximate to one another such that the cooling fins diverge from one another in a radially outward direction to define an air path between adjacent cooling fins,
• wherein the trailing edge includes a radial fin, a first aerodynamically profiled surface, and a plurality of spaced apart cooling projections positioned between the first aerodynamically profiled surface and the inner edge, and
• wherein the leading edge includes a base adapted to connect with the component so that heat is transferred from the component to the cooling fin, a second aerodynamically profiled surface, and a slot positioned between the base and the second aerodynamically profiled surface;
• a base ring including a collar profile that complements the slot, the collar profile is in contact with the slot of each cooling fin and retains the cooling fins in fixed relation with one another;
• and
• a radial shield including an upper edge and a lower edge separated by a distance, the radial shield is in contact with a portion of the outer edges of the cooling fins, and the radial shield defines an air inlet between the lower edge and the second aerodynamically profiled surface and defines an air outlet between the upper edge and the radial fin, and
• wherein heat is removed from the component by an air inflow through the air inlet, the radial shield channels the air inflow through the air path and over the cooling surfaces, the first aerodynamically profiled surface redirects a portion of the air inflow over the cooling projections, and the radial shield is operative to channel the air inflow into an air outflow that exits through the air outlet and along an axis that is substantially parallel with the inner edges.
