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,
• wherein the first and second flow paths are stacked, and occupy the approximately full width of the packing module in the width direction, respectively,
• wherein the packing module further comprises:
• first primary packing sheets, which limit the formation of the first flow path;
• second primary packing sheets, which limit the formation of the second flow path and arranged in an alternative direction with the first primary packing sheets;
• and
• partition sheets, which separate the first primary packing sheets from the second primary packing sheets,
• wherein the first and second import portions and/or the first and second export portions are formed as a triangular shape having a vertex angle pointing to the outside of the packing module when viewed in a stack direction of the packing module,
• wherein the partition sheets comprise:
• first partition sheets, which are located on one side of the first primary packing sheets and matched with the first primary packing sheets to form a first module group;
• and
• second partition sheets, which are located on one side of the second primary packing sheets and matched with the second primary packing sheets to form a second module group;
• and
• the first module group and the second module group are stacked to form the packing module, and
• wherein when the first and second module groups are stacked, export portion water-retaining ribs are formed on the outer surfaces of the first and second folding groups of the first and second export portions.

• and the first module group and the second module group are stacked to the packing module;
• in the upper portion of the packing module:
• when viewed in the stack direction of the packing sheets, the packing module forms, in a vertical direction, upper flow guide portions with an upper triangle having a vertex angle pointing to the upper side of the packing module, and upper longitudinal flow guide portions communicating a bevel edge of the upper triangle on an inflow side;
• in the lower portion of the packing module:
• when viewed in the stack direction of the packing sheets, the packing module forms, in a vertical direction, lower flow guide portions with a lower triangle having a vertex angle pointing to the lower side of the packing module, and lower longitudinal flow guide portions communicating a bevel edge of the upper triangle on an outflow side;
• the first primary packing sheets guide, at the upper flow guide portions, water from a bevel edge on one side as the bevel edge on the inflow side to the middle part of the approximately full width of the first primary packing sheets, and guide, at the lower flow guide portions, the water from the middle part of the approximately full width of the first primary packing sheets to a bevel edge on the other side as the bevel edge on the outflow side or the bevel edge on the one side;
• for the first primary packing sheets, the upper longitudinal flow guide portions are arranged at positions corresponding to the bevel edge on the one side, and the lower longitudinal flow guide portions are arranged at position corresponding to the bevel edge on the other side or the bevel edge on the one side;
• the second primary packing sheets guide, at the upper flow guide portions, water from a bevel edge on the other side as the bevel edge on the inflow side to the middle part of the approximately full width of the second primary packing sheets, and guide, at the lower flow guide portions, the water from the middle part of the approximately full width of the second primary packing sheets to a bevel edge on one side as the bevel edge on the outflow side or the bevel edge on the other side;
• and
• for the second primary packing sheets, the upper longitudinal flow guide portions are arranged at positions corresponding to the bevel edge on the other side, and the lower longitudinal flow guide portions are arranged at positions corresponding to the bevel edge on the one side or the bevel edge on the other side.
