The header is provided with a pair of branched tubes (20), (21) respectively on both sides or a side of the passage (17) for heat- transfer medium. The tubes have respective valves (12), (13) and connect to passages (30), (31) for heat-transfer medium which have caps (32), into which fit the open ends of collector tubes(2) in sealing with an "O" ring (33) against liquid leak. Projective push means (10), (11) provided on the front of a supporter (7) open the valves (12), (13) to make passages (28), (29) through between the collectors and the header (1). Free of load, springs (22), (23) close the valves. Thus, partial damages of collector tubes may be easily replaced.
