         9 . The evaporative cooling system of  claim 6 , wherein the height is between 3.75 mm and 4 mm. 
     
     
         10 . The evaporative cooling system of  claim 6 , wherein each of the linear undulations extends in a direction that is at an angle from horizontal. 
     
     
         11 . The evaporative cooling system of  claim 7 , wherein the air-water contact body is assembled such that alternating sheets of the plurality of sheets include linear undulations extending in a first direction and at a first angle from horizontal and intervening sheets of the plurality of sheets between the alternating sheets of the plurality of sheets include linear undulations extending in a second direction and at a second angle from horizontal. 
     
     
         12 . The evaporative cooling system of  claim 1 , wherein:
 the first direction and the second direction are different; and   the first angle and the second angle are the same.   
     
     
         13 . The evaporative cooling system of  claim 1 , wherein:
 the first direction and the second direction are different; and   the first angle and the second angle are different.   
     
     
         14 . The evaporative cooling system of  claim 6 , wherein the air-water contact body is an evaporative media pad. 
     
     
         15 . The evaporative cooling system of  claim 14 , wherein the evaporative media pad is composed of cellulose paper. 
     
     
         16 . The evaporative cooling system of  claim 14 , wherein the plurality of sheets are assembled such that the plurality of linear undulations of adjacent sheets are in contact with each other.
