PURPOSE: To prevent a manifold from turning when fluid flow tubes are fitted thereto. CONSTITUTION: In the tubular wall 1 having a number of through apertures 3 arranged in the axial direction and fitted with the fluid flow tubes of a heat exchanger, the apertures are located on the side of a contact plane P parallel with the axis of the tubular wall 1. The contact plane P abuts against the tubular wall 1 at least two contact parts A, B spaced apart in the circumferential fringe direction thus preventing a manifold from turning when fluid flow tubes are fitted thereto. |
