Liquid cooled heat exchanger with enhanced flow
First Claim
1. A liquid-cooled heat sink comprising:
- a housing including a side wall extending from the perimeter of a bottom wall and a lid sized to engage said peripheral side wall so as to form a chamber within said housing;
a fluid inlet port and a fluid outlet port defined through said lid so as to be in fluid communication with said chamber; and
a fin comprising a plurality of corrugations positioned within said chamber so that at least one of said corrugations engages said bottom wall and at least one of said corrugations is secured to a surface of said lid, wherein at least one hole is defined through at least one of said corrugations and arranged so as to receive at least one pin when said fin is positioned within said chamber such that a portion of said corrugation and said surface of said lid engage said pin, so that said fin is fixed in position within said housing.

Abstract
A liquid-cooled heat sink is provided having a cooling housing including a peripheral side wall extending from the perimeter of a bottom wall and a lid sized to engage the peripheral side wall so as to form a chamber. A fluid inlet port and a fluid outlet port are defined through the lid, and disposed in fluid communication with the chamber. In one embodiment, a plurality of pins project outwardly from the bottom wall so as to be positioned within the chamber and arranged in a staggered pattern. The pins include an end that engages the undersurface of the lid. In an alternative embodiment, a corrugated fin having a plurality of corrugations is positioned within the chamber so that at least one of the corrugations engages the bottom wall and at least one of the corrugations engages the under surface of the lid.
