Packing sheet, packing module and cooling tower

A packing module having:

• 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;
• a first functional portion located between the first import portion and the first export portion;
• and
• a second functional portion located between the second import portion and the second export portion;
• the first functional portion and the second functional portion being formed on approximately full width of the packing sheet for heat exchange;
• the first import portion is formed to guide water flowing from one side of the packing module in the width direction to the first functional portion by using a flow guide slot arranged obliquely, so as to form a water film on surface of wall of the first functional portion;
• the second import portion is formed to guide water flowing from the other side of the packing module in the width direction to the second functional portion by using a flow guide slot arranged obliquely, so as to form a water film on surface of wall of the second functional portion.
