An automotive condenser is disclosed as having vertically upstanding first and second headers communicating with inlet and outlet connections, respectively, and generally horizontally disposed tubes connected into such headers, wherein the second header is dimensioned to permit refrigerant gas to separate from refrigerant liquid to provide an upper volume of refrigerant gas and a lower volume of refrigerant liquid. The condenser may be provided with at least one horizontally extending subcooling tube placing the lower volume in flow communication with the outlet.

A refrigeration condenser comprising in combination: first and second generally vertically upstanding headers; a plurality of generally horizontally disposed condenser tubes, at least certain of said tubes having inlet ends connected into said first header and outlet ends connected into said second header and forming parallel refrigerant gas conducting flow paths connecting said first and second headers; a refrigerant gas inlet communicating with said inlet ends and a refrigerant liquid outlet communicating with a lower portion of said second header; said second header being dimensioned of sufficiently large internal cross-sectional area such that when said condenser is charged with sufficient refrigerant to maintain a liquid to gas interface above said refrigerant liquid outlet refrigerant gas is permitted to substantially separate from refrigerant liquid produced from said refrigerant gas passing through said tubes to produce an upper volume of refrigerant gas and a sufficient lower volume of refrigerant liquid within said second header and the velocity of refrigerant liquid flowing towards said refrigerant liquid outlet is not sufficient to sweep refrigerant gas entering said lower volume from the lowermost of said flow paths, flowing under the influence of gravity from the lower volume to the upper volume, through said refrigerant liquid outlet.
