Abstract
A heat exchanger includes a metal tube and a composite polymer fin in thermal contact with the metal tube. The fin is formed of a polymer and a thermally conductive filler such that the fin has a thermal conductivity greater than or equal to 0.5 Watts per meter Kelvin.
Claims18
A heat exchanger comprising:
- a metal tube;
- and
- a composite polymer fin in thermal contact with the metal tube, the composite polymer fin being formed of a polymer and a thermally conductive filler such that the composite polymer fin has a thermal conductivity greater than or equal to 0.5 Watts per meter Kelvin, wherein the thermally conductive filler includes particles that are partially embedded within the polymer and partially protrude from a first surface of the polymer and the first surface of the polymer is coated with a metallic coating.
A heat exchanger comprising:
- a plurality of metal tubes;
- and
- a plurality of composite polymer fins in thermal contact with the metal tubes, the composite polymer fins being formed of polymer and a thermally conductive filler such that the composite polymer fins have a thermal conductivity greater than or equal to 0.5 Watts per meter Kelvin, wherein the thermally conductive filler includes particles that are partially embedded within the polymer and partially protrude from a first surface of the polymer and the first surface of the polymer is coated with a metallic coating.
