Heat exchanger with double vibration isolation
First Claim
1. A heat exchanger assembly, comprising:
- an enclosure having an enclosure wall;
a first heat exchanger disposed within said enclosure;
a vibration isolation plate interposed between said enclosure wall and said first heat exchanger;
a first resilient member coupling said first heat exchanger to said vibration isolation plate;
a second resilient member coupling said vibration isolation plate to said enclosure wall; and
wherein said vibration isolation plate is thicker than said enclosure wall.

Abstract
A heat exchanger within a sheet metal enclosure includes mounting structure that provides double vibration isolation to minimize noise. The mounting structure includes at least one resilient vibration isolator that couples the heat exchanger to a vibration isolation plate, and includes other similar isolators that couple the plate to the enclosure. The mass of the plate is sufficient to somewhat emulate a dual mass/spring system having two degrees of freedom. To this end, the plate is preferably thicker than the sheet metal walls of the enclosure. The double vibration isolated heat exchanger is especially applicable to systems having several heat pumps that are mounted overhead. In some embodiments, the heat pump'"'"'s refrigerant compressor is also resiliently mounted to the vibration isolation plate.
