Abstract

PURPOSE: To increase the cooling effect considerably, by setting the pitch angle at the root associated with fan blade to 60°W70° while decreasing the pitch angle toward the tip of blade thereby reducing the resistance considerably.
CONSTITUTION: The pitch angle 91 at the portion r1=1.1r0W1.2r0 for the radius ro so the root effective as rotary blade of fan 4 or fixing base 30 of fan 3 is set in the range of 60°W70° where max. air flow is obtained with small noise, to provide conical air flow having point in front of fan 3. When setting the pitch angle θ1 it is set for the root at effective pitch angle section except the fan blade base of r1= 1.1r0W1,2r0 and reduced toward the tip of fan blade 4.
