Condenser for automotive air conditioning systems
First Claim
1. An air conditioning system condenser, comprising:
- a condenser first header having an outer peripheral surface;
a condenser second header;
a plurality of parallel flat plate pipes positioned between said first and second headers, said flat plate pipes having flat surfaces;
corrugated fins positioned between said flat plate pipes and contacting said flat surfaces; and
first union joint means on said first header for discharging refrigerant in said first header to a condenser refrigeration circuit, said first union joint means comprising a union portion for connection with the condenser refrigeration circuit, a fixed portion having a receiving surface fitted on said outer peripheral surface, and a liquid-refrigerant extended discharge outlet pipe connected to said union portion, said extended discharge outlet pipe extending downwardly within said first header to a position adjacent an inside bottom of said first header.

Abstract
A condenser, for use in automotive air conditioning systems, including a first header, a second header, a plurality of parallel flat plate pipes arranged between the first and second headers, and corrugated fins between the flat plate pipes for contacting the flat surfaces thereof. A second union joint on the second header introduces refrigerant into the second header. A first union joint on the first header discharges refrigerant to a refrigeration circuit. The first union joint includes a union portion for connecting the first union joint with the refrigeration circuit, a fixed portion with a receiving surface which is fitted on the outer peripheral surface of the first header, and a pipe which is connected to the union portion. The pipe extends downwardly within the first header to the bottom of the first header, and thus, the first union joint discharging liquid refrigerant can be disposed anywhere on the first header.
