Abstract
Abstract A fluid heat exchanger for cooling an electronic component having a housing for receiving heat from the electronic component in which the housing has a fluid inlet and an outlet at opposite ends of the housing. The cross-sectional area of the housing for conveying fluid from the inlet to the outlet decreases from the inlet to the outlet thereby reducing pressure drop without sacrificing thermal performance. The cross-sectional area may be decreased by tilting a top of the housing relative to a bottom, or providing a plurality of fins separated by channels in which the cross-sectional area of the channels decreases from the inlet to the outlet.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
97 words
A fluid heat exchanger for cooling an electronic component comprising, a housing having a base for receiving heat from an electronic component and having first and second opposing ends, a fluid inlet at the first end and a fluid outlet at the second end, a plurality of spaced fins connected to the base and extending from the inlet to the outlet, said fins separated by fluid channels in which the cross-sectional area of the channels decreases from the inlet to the outlet, and wherein the cross-sectional area of the fins increases from the inlet to the outlet.
Claim 2
Dependent Claim
97 words
A fluid heat exchanger for cooling an electronic component comprising, a housing having a base for receiving heat from an electronic component and having first and second opposing ends, a fluid inlet at the first end and a fluid outlet at the second end, a plurality of spaced fins connected to the base and extending from the inlet to the outlet, said fins separated by fluid channels in which the cross-sectional area of the channels decreases from the inlet to the outlet, and wherein the cross-sectional area of the fins increases from the inlet to the outlet.
Claim 3
Dependent Claim
108 words
A fluid heat exchanger for cooling an electronic component comprising, a housing having a base for receiving heat from an electronic component and having first and second opposing ends, a fluid inlet at the first end and a fluid outlet at the second end, a plurality of spaced fins connected to the base and extending from the inlet to the outlet, said fins separated by fluid channels in which the cross-sectional area of the channels decreases from the inlet to the outlet, and wherein said fluid channels are formed by the fins which are tapered in a direction parallel to said base from the inlet to the outlet.
Claim 4
Dependent Claim
108 words
A fluid heat exchanger for cooling an electronic component comprising, a housing having a base for receiving heat from an electronic component and having first and second opposing ends, a fluid inlet at the first end and a fluid outlet at the second end, a plurality of spaced fins connected to the base and extending from the inlet to the outlet, said fins separated by fluid channels in which the cross-sectional area of the channels decreases from the inlet to the outlet, and wherein said fluid channels are formed by the fins which are tapered in a direction parallel to said base from the inlet to the outlet.
Claim 5
Dependent Claim
131 words
A fluid heat exchanger for cooling an electronic component comprising, a housing for receiving heat from an electronic component, said housing having a fluid inlet and a fluid outlet at opposite ends of the housing, the cross-sectional area perpendicular to the direction of fluid flow in the housing for conveying fluid from the inlet to the outlet decreasing from the inlet to the outlet, the housing includes a top and a wall, said wall adapted to be positioned adjacent said electronic component in a heat conducting relationship, a plurality of fins, separated by channels, positioned in the housing and connected to the wall, said channels intersecting a single plane extending parallel to said wall, and the cross-sectional width of the channels in the plane decreasing from the inlet to the outlet.
