ABSTRACT:
The present invention provides a shroud for cooling a heatsink that is associated with a heat generating electrical component. Conventionally, the heatsink has a base portion with a first side and an oppositely disposed second side. The first side has cooling projections with outer ends that extend from the first side with the second side being attached to the heat generating electrical component. The shroud of the present invention comprises a wall that may be comprised of a thermoplastic or metallic material, The wall extends about and covers a portion of the cooling projections to form a passage for a flow of fluid about the cooling projections. The passage has a varying cross-sectional area to maximize the flow of the fluid about the cooling projections, to thereby enhance transfer of heat from the cooling projections to the fluid flowing through the passage. In one aspect, the varying cross-sectional area is formed by at least one of the walls surround the cooling projections having a concave shape projecting toward the cooling projections.
