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 heat exchanger system, comprising:
a heat exchanger coil;
a cover disposed above the heat exchanger coil and forming a void between the heat exchanger coil and the cover, wherein the cover comprises a venturi orifice configured to direct air through a center of the heat exchanger coil;
a base of a substructure comprising a clamp having a first arm and a second arm, wherein 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 substructure coupled to the base and abutting the cover of the heat exchanger system, wherein the base and the vertical member extend within the void between the heat exchanger coil and the cover, the vertical member is biased against the cover and conforms to a geometry of the void, and the base and vertical member are configured to block air flowing through the heat exchanger from flowing through the void.
2. The heat exchanger system of claim 1 , wherein the vertical member and the base are integrated into a single piece.
3. The heat exchanger system of claim 2 , wherein the base is configured to receive the heat exchanger coil.
4. The heat exchanger system of claim 2 , wherein the base and the vertical member comprise a first cross sectional shape configured to conform to a second cross sectional shape of the void between the heat exchanger and the cover.
5. The heat exchanger system of claim 1 , wherein an angle between the vertical member and the base is between 80 degrees and 110 degrees.
6. The heat exchanger system of claim 1 , wherein an angle between the vertical member and the base is less than 90 degrees.
7. The heat exchanger system of claim 1 , wherein the first arm is configured to exert a first biasing force against a first surface of the heat exchanger coil and the second arm is configured to exert a second biasing force against a second surface of the heat exchanger coil.
8. The heat exchanger system of claim 1 , wherein the vertical member is coupled to the cover via a fastener extending through the vertical member and the cover.
9. A heat exchanger, comprising:
a heat exchanger coil;
a cover disposed above the heat exchanger coil and comprising a venturi orifice configured to direct air through a center of the heat exchanger coil; and
a substructure disposed between the heat exchanger coil and the cover, wherein the substructure comprises a base adjacent to the heat exchanger coil and a vertical member adjacent to the cover, wherein the base of the substructure comprises a first arm and a second arm, and wherein the first arm and the second arm are configured to cooperatively apply a clamping force to the heat exchanger coil, wherein the substructure is configured to block air from flowing through a void between the heat exchanger coil and the cover, and wherein the substructure comprises a compliant material compressed against the cover and conforming to a geometry of the void between the heat exchanger coil and the cover.
10. The heat exchanger of claim 9 , wherein the substructure is coupled to the cover via an interference fit.
