A heat exchange apparatus is provided with an indirect evaporative heat exchange section. The indirect evaporative heat exchange section includes a series of serpentine tubes, and an evaporative liquid is passed downwardly onto the indirect heat exchange section. The evaporative liquid is collected in a sump and then pumped upwardly to be distributed again across the indirect heat exchange section.

An improved heat exchange apparatus is provided with an indirect evaporative heat exchange section including a series of serpentine tubes with run sections and return bend sections of both normal and increased height. A direct heat exchange section may be provided in the vertical spacing between run sections formed by the increased height return bends.

The present invention relates to a cooling tower for cooling water, improved to evenly spray the cooling-water, wherein each component is manufactured in a modularized form and then each module is integrated and installed at an installation site to correspond to the scale of the cooling tower. The cooling tower includes a water tank, a filling material, a cooling-water circulation facility, an eliminator, and a fan, wherein, between the filling material and the water tank, an air intake port through which external air is introduced and a guide having a concave cross-sectional shape to guide the introduced air to the center using a pressure difference between the inside and the outside thereof are additionally provided so that cooling efficiency of the cooling-water can be improved and productivity of the cooling tower as well as convenience in transportation and installation can be maximized.

A double wall panel member for use in a panel wall is provided which includes a tongue-configured end and a groove-configured end. The panel member includes a first outer wall spaced laterally from a second outer wall, and the groove-configured end has a first groove wall portion extending from the first outer wall and a second groove wall portion extending from the second outer wall, where the first groove wall portion extends further outward than the second groove wall portion. When connected, the wall panel members are assembled with the groove end pointing or oriented upward (not downward) and the tongue end pointing or oriented downward (not upward).

A packing module includes first and second flow paths which exchange heat between water sprayed from above and air flowing from below; a first import portion for importing water sprayed from one side of the packing module into the first flow path; a second import portion for importing water sprayed from the other side of the packing module into the second flow path; a first export portion for guiding water flowing out from the first water path to one side of the packing module for discharging; and, a second export portion for guiding water flowing out from the second water path to the other side of the packing module for discharging. Two flow paths in the packing module operate in different operation modes, so that water or wind flows through one flow path to cool water while air flows through the other flow path for heat exchange through partition walls.

A cooling tower structure having a concrete perimeter foundation wall with a perimeter rebar grouping. The structure includes at least four columns formed of CMU blocks with at least two columns being freestanding and positioned approximate corners of the foundation wall. Each column further includes a column rebar grouping being tied into the perimeter rebar grouping. At least three bond-beams formed of CMU blocks are connected between the columns at least four feet above the foundation. The bond-beams include beam rebar groupings tying into at least one of the column rebar groupings. The structure includes housing walls formed of CMU blocks extending upward from the bond beams. At least one fan is on at least one pedestal column positioned within the foundation wall, with a pedestal rebar grouping extending though the pedestal column from a concrete pedestal footing. A series of water collection troughs are positioned within the cooling tower above the fan and fill media is positioned in the cooling tower above the collection troughs.
