Abstract
An improved heat sink is used to cool electrical and electronic components that generate heat. The heat sink comprises at least one primary corrugated fin pack having a continuous series of vertically extending fins defining channels between adjacent pairs of the vertically extending fins. At least one secondary corrugated fin pack fits within the channels of the primary corrugated fin pack, creating a fin pack matrix. The fin pack matrix is then attached to a base plate.
Claims20
An improved heat sink comprising:
- at least one primary corrugated fin pack having a continuous series of primary vertically extending fins defining channels between adjacent pairs of the primary vertically extending fins;
- at least one secondary corrugated fin pack having a continuous series of secondary vertically extending fins, wherein the at least one secondary corrugated fin pack fits within the channels of the at least one primary corrugated fin pack;
- a fin pack matrix created by inserting the at least one secondary corrugated fin pack in between adjacent pairs of the vertically extending fins of the at least one primary corrugated fin pack;
- at least one base plate, wherein heat is conducted from the at least one base plate into the at least one primary corrugated fin pack and then into the at least one secondary corrugated fin pack;
- and
- means for attaching the fin pack matrix to the at least one base plate.
A method for cooling one or more heat-generating electrical or electronic components, the method comprising the steps of:
- providing at least one primary corrugated fin pack having vertically extending fins defining channels between adjacent pairs of the vertically extending fins;
- providing at least one secondary corrugated fin pack having vertically extending fins, wherein the vertically extending fins of the at least one primary corrugated fin pack are thicker and wider-spaced than the vertically extending fins of the at least one secondary corrugated fin pack;
- inserting the at least one secondary corrugated fin pack in the channels of the at least one primary corrugated fin pack to create a fin pack matrix;
- and
- attaching the fin pack matrix to at least one base plate, wherein heat is conducted from the at least one base plate into the at least one primary corrugated fin pack and then into the at least one secondary corrugated fin pack.
