Simple distributor for inlet manifold of microchannel heat exchanger

A distributor for an inlet manifold of a microchannel heat exchanger, the distributor comprising:

• a nozzle adapted to be fluidically connected to an output of a supply tube of a refrigeration line of the heat exchanger within an inlet manifold of the heat exchanger, wherein the supply tube is at least partially disposed within the inlet manifold of the heat exchanger,
• the nozzle comprising:
• a first hollow portion having a round cross-section and adapted to be fluidically connected to the supply tube within the inlet manifold;
• and
• a second hollow portion having an oval or elliptical cross-section, wherein the second hollow portion is fluidically connected to the first hollow portion such that the nozzle gradually transitions from the first hollow portion to the second hollow portion within the inlet manifold and flow area of the nozzle reduces in a direction from the first hollow portion to the second hollow portion.
