Heat exchanger, in particular for an atmospheric cooling tower

A heat exchanger for exchanging heat between a first fluid and at least a second fluid, of the type comprising a horizontal battery of tubes of substantial length supported at intervals by spacer devices, said first fluid circulating through said tubes and said second fluid passing through said battery transversely with respect to the tubes, wherein said battery is suspended in at least a part of its length from suspension members to which said spacer devices are suspended, lower hooking points on the spacer devices for said suspension members, upper hooking points for said suspension members, said upper hooking points offset toward the other end of the battery relative to the vertical from lower hooking points on the spacer devices, wherein the tubes of said battery are rectilinear and the battery has included first and second header means one at each end of the tubes of said battery, said first header fixed on said support structure, and said battery including the second header is suspended freely in the remainder of its length, further wherein said suspension members are oriented in the longitudinal direction of the battery, and wherein said upper hooking points are offset toward said second header relative to the vertical from said lower hooking devices.
