Claims7
A brazed condenser for an air conditioner comprising:
- a block of tubes and fins,
- two collecting tubes between which said block is arranged, each collecting tube being a one-piece tube,
- a tube-shaped collector which is mounted laterally with respect to one of the collecting tubes,
- tack-weld seams by which said one of the collecting tubes is connected with the tube-shaped collector, and
- a tube piece which is coaxial with the collector by which the collector is lengthened, the coaxial tube piece including an external longitudinal groove forming a contact surface for said one of the collecting tubes.
