Patent ID: 8596089

Claim:
A refrigerant distribution plate comprising: a plurality of refrigerant inlet chambers formed inside the refrigerant distribution plate, the plurality of refrigerant inlet chambers coupled with a manifold to receive refrigerant entering the refrigerant distribution plate and to disperse the received refrigerant to the plurality of refrigerant inlet chambers, the plurality of refrigerant inlet chambers extending lengthwise from a first end of the refrigerant distribution plate to a second end of the refrigerant distribution plate, wherein refrigerant flows in a direction from the first end of the refrigerant distribution plate toward the second end of the refrigerant distribution plate within each of the plurality of refrigerant inlet chambers; a plurality of ridges disposed on a side of the refrigerant distribution plate, each ridge of the plurality of ridges extending from an outside end of the side of the refrigerant distribution plate such that adjacent ridges of the plurality of ridges form paths that extend from the refrigerant distribution plate to an evaporator core connected to the refrigerant distribution plate, each path being aligned with a flow row on the evaporator core, a plurality of hole sets, each of the plurality of hole sets formed between adjacent ridges, each of the hole sets fluidly communicating with one of the refrigerant inlet chambers located between adjacent ridges; and each one of the plurality of hole sets formed between adjacent ridges to form a refrigerant flow path to direct the refrigerant to the respective flow row on the evaporator core.
