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.

An industrial heat exchange system includes a cooling tower having an exterior wall and a top aperture. An exhaust fan is positioned near the top aperture. A mixing space of the cooling tower is positioned below the exhaust fan. An ambient air inlet extends through the exterior wall for providing outside air into the mixing space. A manufacturing air inlet extends through the exterior wall for providing heated air into the mixing space. The outside air and the heated air combine within the mixing space to define control air that is maintained above a minimum temperature. The heated air is delivered through an air duct extending from a manufacturing facility to the manufacturing air inlet.

The present invention provides a packing sheet, a packing module and a cooling tower. The packing module has: stacked first flow path and second flow path which exchange heat between water sprayed from above and air flowing from below to above; a first import portion for importing water sprayed from one side of the packing module in a width direction into the first flow path; a second import portion for importing water sprayed from the other side of the packing module in the width direction 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 in the width direction 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 in the width direction for discharging. In accordance with the present invention, two flow paths in the packing module can operate in different operation modes, so that water or wind can flow through one flow path to cool water while only air can flow through the other flow path to realize heat exchange through partition walls, thereby reducing fog discharge when wet air is discharged to the atmosphere.
