Air-applying device having a case with an air inlet port, a cooling unit having the air-applying device, and an electronic apparatus having the air-applying device

   
   

An air-applying device has an impeller having a center of rotation, and a case which contains the impeller. The case includes a first edge defining an inlet port of air which exposes the center of rotation, a second edge defining an outlet port of air, and a high-pressure region which presents upon operational rotation of said impeller. The high-pressure region is located within the case along a peripheral portion of the impeller. A distance between the center of rotation of the impeller and the first edge is shorter in the direction from the center of rotation to a center of the high-pressure region than from the center of rotation to region other than the high-pressure region.
