Abstract
A heat sink is disclosed for use with a heat exchanger employing a circular fan which forces air in a volute path about a central axis. The heat sink includes a plurality of heat exchanging sections disposed in the path about the axis. Each heat exchanging section includes a thermally conductive sheet folded into alternating ridges and troughs defining generally parallel spaced fins. The heat exchanging sections are oriented such that the fins of each section are at an angle to the fins of an adjacent section.

A heat sink for use with a heat exchanger employing a circular fan which forces air in a volute path about a central axis, comprising:
- a plurality of heat exchanging sections disposed in said path about said axis,
- each heat exchanging section including a thermally conductive sheet folded into alternating ridges and troughs defining generally parallel spaced fins, and
- said heat exchanging sections being oriented such that the fins of each section are at an angle to the fins of an adjacent section.
A heat sink for use with a heat exchanger employing a circular fan which forces air in a volute path about a central axis, comprising:
- a plurality of generally rectangular heat exchanging sections disposed in said path about said axis,
- each heat exchanging section including a thermally conductive sheet folded into alternating ridges and troughs defining generally parallel spaced fins, and
- said heat exchanging sections being oriented such that the fins of each section are generally perpendicular to the fins of an adjacent section.
A heat exchanger assembly, comprising:
- a housing;
- a circular fan mounted on the housing for forcing air in a volute path about a central axis;
- and
- a heat sink assembly including
- a plurality of heat exchanging sections disposed in said path about said axis, each heat exchanging section including a thermally conductive sheet folded into alternating ridges and troughs defining generally parallel spaced fins, and said heat exchanging sections being oriented such that the fins of each section are at an angle to the fins of an adjacent section.
