<p>An air-air heat exchanger (1) and an air-freon heat exchanger (2) form an element of a dryer for compressed air, both exchangers (1, 2) have the configuration of a winding; the length thereof is of one spiral and a half. The air-air heat exchanger (1) comprises an outer pipe (3) and at least three inner pipes (4), whereas the air-freon exchanger (2) comprises an outer pipe (3) and a coaxial inner pipe (5) inside which are arranged pipes (4) in contact between each other. Both exchangers are provided with a sleeve (6); the manifolds (8, 9) are connected approximately perpendicularly to the sleeve (6). </p> |
