Abstract
In one instance, an isolator for a heating, ventilating, and cooling (HVAC) system is provided that is a formed plastic member that is disposed between dissimilar metals of the bottom of the condenser and a base pan that supports the condenser or between two dissimilar metals of another HVAC heat exchanger. The isolator separates the two dissimilar metals involved from each of those components and also provides gaps or apertures to drain any water that otherwise might become standing water that potentially causes oxidation or increased oxidation. Other aspects are disclosed.
Claims6
A method for isolating a first metal of a heat exchanger of a heating ventilating and air cooling (HVAC) system from a second metal of a support portion of the HVAC system, wherein the first metal is different from the second metal, the method comprising:
- releaseably coupling a plastic isolator to a bottom longitudinal edge of the heat exchanger, wherein the heat exchanger forms a parallelepiped member;
- disposing the heat exchanger on the support portion of the HVAC system with the plastic isolator against the support portion;
- and
- wherein the plastic isolator comprises:
- a plastic member having a substantially u-shaped lateral cross section formed by opposing side walls,
- wherein the opposing side walls run parallel to the bottom longitudinal edge of the heat exchanger when coupled, and having a receiving area defining an interior;
- wherein a center portion of the u-shaped lateral cross section forms the receiving area and is substantially flat, and
- wherein the plastic member has a longitudinal length, which is a long dimension of the plastic isolator that runs parallel to the bottom longitudinal edge of the heat exchanger when coupled.
