Abstract
A heat exchanger that includes a first manifold; a second manifold; a plurality of refrigerant tubes configured to fluidically couple the first and second manifolds; a plurality of fins placed between the plurality of refrigerant tubes, such that the fins and refrigerant tubes define a core having a plurality of open channels that allow air to flow there through; and a water-shedding device positioned approximate to the first manifold with a separation distance being maintained there between. At least a portion of the water-shedding device extends into one or more fin free windows located between the plurality of refrigerant tubes, such that condensate is extracted from between the refrigerant tubes.
Claims18
A heat exchanger comprising:
- a first manifold;
- a second manifold;
- a plurality of refrigerant tubes configured to fluidically couple the first and second manifolds;
- a plurality of fins placed between the plurality of refrigerant tubes, such that the fins and refrigerant tubes define a core having a plurality of open channels that allow air to flow there through;
- and
- a water-shedding device positioned approximate to the first manifold with a separation distance being maintained there between;
- wherein at least a portion of the water-shedding device extends into one or more fin free windows located between the plurality of refrigerant tubes, such that condensate is extracted from between the refrigerant tubes;
- wherein the water-shedding device includes a first end having width w1 and a second end having width w2 wherein w2>w1, such that an angled gradient is created and the extracted condensate flows down the gradient.
A water-shedding device for use with a heat exchanger that includes a core defined by a plurality of refrigerant tubes and fins located between first and second manifolds,
- the water-shedding device configured such that a separation distance is maintained when the device is fastened to the first manifold, and
- at least a portion of the water-shedding device extends into one or more fin free windows located between the plurality of refrigerant tubes, such that condensate is extracted from between the refrigerant tubes;
- wherein the water-shedding device includes a first end having width w1 and a second end having width w2, wherein w2>w1, such that an angled gradient is created and the extracted condensate flows down the gradient.
