Abstract
Abstract A fluid impingement heatsink structure in which a heatsink (30) has a plurality of cooling fins (34) and a substantially planar enveloping surface through which an impinging fluid flow may enter. A solid shroud (36) can be placed on the heatsink to cover the planar surface so that fluid then may flow serially across the cooling fins but is prevented from flowing in a direction perpendicular to the plane defined by the planar surface. When the shroud is mounted on the heatsink, the heatsink and shroud form a unitary heatsink structure.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
111 words
A fluid impingement heatsink structure (10, 30, 40) comprising: a) a heatsink having a base (15, 32, 42) and mounted thereon a plurality of cooling fins (12, 34, 44), said heatsink having at least one substantially planar enveloping surface through which fluid can flow; and characterized by: b) a solid shroud (20, 36, 46) removably connected to said heatsink and substantially covering said at least one planar enveloping surface thereof so that fluid can flow serially across said cooling fins but is prevented from flowing in a direction perpendicular to the plane defined by said planar surface when said shroud is mounted on said heatsink to form a unitary heatsink structure.
Claim 2
Dependent Claim
111 words
A fluid impingement heatsink structure (10, 30, 40) comprising: a) a heatsink having a base (15, 32, 42) and mounted thereon a plurality of cooling fins (12, 34, 44), said heatsink having at least one substantially planar enveloping surface through which fluid can flow; and characterized by: b) a solid shroud (20, 36, 46) removably connected to said heatsink and substantially covering said at least one planar enveloping surface thereof so that fluid can flow serially across said cooling fins but is prevented from flowing in a direction perpendicular to the plane defined by said planar surface when said shroud is mounted on said heatsink to form a unitary heatsink structure.
Claim 3
Dependent Claim
16 words
The fluid impingement heatsink structure in accordance with claim 1 wherein said fluid comprises a liquid.
Claim 4
Dependent Claim
24 words
The fluid impingement heatsink structure in accordance with claim 2 wherein said liquid is selected from the group comprising water, freon and liquid nitrogen.
Claim 5
Dependent Claim
16 words
The fluid impingement heatsink structure in accordance with claim 1 wherein said fluid comprises a gas.
Claim 6
Dependent Claim
17 words
The fluid impingement heatsink structure in accordance with claim 4 wherein said gas comprises air or helium.
Claim 7
Dependent Claim
25 words
The fluid impingement heatsink structure in accordance with claim 1 wherein said heatsink has a mounting plate (16) operatively connected thereto for receiving said shroud.
Claim 8
Dependent Claim
28 words
The fluid impingement heatsink structure in accordance with claim 6 wherein said shroud comprises attachment means (22, 26, 48, 50) for connecting said shroud to said mounting plate.
Claim 9
Dependent Claim
25 words
The fluid impingement heatsink structure in accordance with claim 1 further comprising: c) sealing means (24) operatively connected to said shroud to prevent fluid leakage.
Claim 10
Dependent Claim
21 words
The fluid impingement heatsink structure in accordance with claim 8 wherein said sealing means comprises a resilient material, such as rubber.
Claim 11
Dependent Claim
99 words
A fluid impingement heatsink structure in accordance with claim 1 comprising: a) a heatsink having a plurality of non-planar cooling fins (34), said heatsink having a base (32) and three substantially planar enveloping surfaces through which fluid can flow; and b) a solid shroud (36) removably connected to said heatsink for substantially covering said three planar surfaces thereof so that fluid can flow serially across said cooling fins but is prevented from flowing in directions perpendicular to the planes defined by said three enveloping surfaces when said shroud is mounted on said heatsink to form a unitary heatsink structure.
