Abstract
A heat exchange comprises a battery of rectilinear tubes of synthetic plastic material connected at their respective ends to headers. At least one of the headers is fixed to the wall of the tower and the remainder of the exchanger is mounted by suspension members to allow free expansion of the tubes of the battery.
Claims9
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 and including inlet and outlet means for the first fluid comprising an inlet collector and an outlet collector to which the respective ends of each of said tubes are connected, said tubes being coiled to-and-fro in vertical planes extending in the longitudinal direction of the battery, a rigid support structure, means connecting the inlet collector and the outlet collector to the rigid support structure, said suspension members including first hooking points on each of said spacer devices, means connecting the lower ends of the suspension members to the first hooking points, second hooking points for each of the suspension members, said second hooking points positioned above the first hooking points of the spacer devices and horizontally offset in a direction to continuously urge its connected spacer device and the tubes supported therein away from the rigid support structure to thereby maintain the horizontal path of said battery of tubes during expansion and contraction of the tubes thereof, and wherein at least some of said spacer devices are intermediate the ends of said battery and urged away from said rigid support structure by said suspension members and wherein each of said spacer devices comprises a rigid frame having openings for support and passage of said tubes.
A heat exchanger as claimed in claim 7, comprising a plurality of tubes coiled to-and-fro and disposed parallel to each other in each of said vertical planes.
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 including means for directing the first fluid through said tubes, said means including a first water box and a second water box to which the tubes are connected in a sealed manner, a rigid support structure connected to the first water box, said suspension members including first hooking points on each of said spacer devices, means connecting the lower ends of the suspension members to the first hooking points, second hooking points for each of the suspension members, said second hooking points positioned above the first hooking points on the spacer devices and horizontally offset in a direction to continuously urge its connected spacer devices and the tubes supported therein away from the rigid support structure to thereby maintain the horizontal path of said battery of tubes during expansion and contraction of the tubes thereof, and wherein at least some of said spacer devices are intermediate the ends of said battery and urged away from said rigid support structure by said suspension members and wherein each of said spacer devices comprises a rigid frame having openings for support and passage of said tubes.
