Condenser with a built-in receiver

In a condenser for a refrigerant fluid circuit, said condenser comprising a plurality of tubes having opposite first and second open ends, a plurality of fin units disposed between said plurality of tubes, first and second header pipes fixedly disposed at said opposite ends respectively, said open ends of said tubes disposed in fluid communication with the interior of said header pipes, said first header pipe having an inlet means for linking the condenser to an external element of the circuit, said second header pipe having an outlet means for linking the condenser to an external element of the circuit, the improvement comprising:

• said second header pipe having first and second open ends, said outlet means having a channel therethrough for hermetically closing said first end of said second header pipe except for said channel, an accumulating means for accumulating refrigerant fluid disposed at and closing said second open end of said second header pipe, and a pipe member having open ends and disposed within said second header pipe, one open end of said pipe member extending beyond said second open end of said second header pipe and terminating within said accumulating means, a second open end of said pipe member hermetically linked to said channel of said outlet means.

In a refrigerant circuit comprising a compressor, a condenser, an expansion element and an evaporator sequentially disposed, the improvement wherein said condenser comprises first and second header pipes and a heat exchanging region, said heat exchanging region further including a plurality of tubes disposed between said first and second header pipes and a plurality of fin units disposed between adjacent tubes, said condenser further comprising an integrally formed receiver disposed adjacent said heat exchanging region and a pipe member disposed in said second header pipe and having a first open end linked to said evaporator and a second open end, said receiver comprising an accumulating tank disposed in fluid communication with said second open end of said pipe member.
