Foam substructure for a heat exchanger
A heat exchanger system includes a heat exchanger coil, a base of a foam structure including a clamp with a first arm and a second arm, where the first arm and the second arm are configured to exert a clamping force against the heat exchanger coil, and a vertical member of the foam substructure coupled to the base and abutting a cover of the heat exchanger system, where the base and the vertical member are configured to block air flowing through the heat exchanger from flowing into a void between the heat exchanger coil and the cover.
1. A heating, ventilating, air-conditioning, and/or refrigeration (HVAC&R) system, comprising:
a foam substructure disposed between a heat exchanger coil and a cover of a heat exchanger, wherein the foam substructure comprises:
a base comprising a sloped surface and a lipped portion extending from the sloped surface, wherein the base is configured to be positioned proximate to the heat exchanger coil, the base has a first shape configured to at least partially conform to a second shape of the heat exchanger coil, and the sloped surface and the lipped portion are configured to block air from flowing between the heat exchanger coil and the cover of the heat exchanger; and
an inner ring extending from the base and configured to be coupled to the cover of the heat exchanger.
2. The HVAC&R system of claim 1 , wherein the base comprises foam and the inner ring comprises rubber.
3. The HVAC&R system of claim 1 , wherein the sloped surface comprises a first height a first distance from the heat exchanger coil and a second height a second distance from the heat exchanger coil, wherein the first height is greater than the second height and the first distance is greater than the second distance.
4. The HVAC&R system of claim 1 , wherein the base and the inner ring are formed from a single piece.
5. The HVAC&R system of claim 1 , wherein the base and the inner ring are integrated into multiple pieces configured to couple to one another.
6. The HVAC&R system of claim 5 , wherein the multiple pieces comprise a first end piece, a second end piece, and a center piece.
7. The HVAC&R system of claim 6 , wherein the first end piece and the second end piece each comprise an extension member configured to be received by a corresponding notch in the center piece.
8. The HVAC&R system of claim 1 , wherein the lipped portion is configured to contact a vertical surface of the cover of the heat exchanger.
9. The HVAC&R system of claim 1 , wherein the inner ring is configured to couple to the cover of the heat exchanger via a fastener.
