PROBLEM TO BE SOLVED: To raise the occupation area of a cooling coil device for a regenerative cooling tower, and besides, raise the heat exchange efficiency. SOLUTION: A cooling coil device 24 has a plurality of cooling coil stacks 26 which are equipped with V-shaped coil pipe circuits 32 and 60 arranged at each plane between the longitudinal axis of a cooling tower 10 and the housing and are in multilayer. Each fan part arranged within each plane rectangular to the longitudinal axis is provided with a coil pipe circuit, and the inlet port 46 and the outlet port 52 of the coil pipe circuit are coupled with a manifold, and refrigerant fluid circulates through coil pipe circuit, and cools the phase transition fluid within a cooling tower 10. A plurality of coil pipe circuits are drawn up in vertical direction, and preferably U-shaped segments on one side being the first coil pipe circuits are drawn up vertically apart from the coil pipe circuits on the other side, thus this coil device disperses the cooling capacity of a cooling stream more equally, and stabilizes and solidifies the phase transition fluid on each coil pipe circuit or in its vicinity more equally. |
