Abstract:
1. A refrigerant distribution device in an inlet header of a multiple tube heat exchanger of a refrigeration system, the system having an expansion device means that delivers a two-phase refrigerant fluid to the inlet header, the multiple tube heat exchanger having an outlet header that delivers a cooled refrigerant fluid that is substantially in a vapor state and a plurality of tubes in fluid communication between the inlet and outlet headers; the refrigerant distribution device including refrigerant flow into the inlet passage and a pressure difference between the inlet passage and the outlet header forcing a liquid flow through the one or more capillary liquid nozzles and a vapor flow through the one or more small diameter nozzles so that the vapor flow impinges upon the liquid flow upon emergence from the nozzles to create a homogeneous mixture of refrigerant extending over substantially the entire length of the inlet header to be delivered relatively uniformly through the plurality of tubes to the outlet header for efficient distribution of the refrigerant fluid.
