Abstract

A method for determining a plurality of fluid flow characteristic curves of a heat-dissipating system, wherein each fluid flow characteristic curve is a relationship curve of one of an air pressure and an air flow and the air pressure and a rotating speed of the heat-dissipating system. The method includes steps of (a) determining a first fluid characteristic curve of the heat-dissipating system at a first condition, (b) obtaining a first variable and a second variable according to the first fluid characteristic curve, (c) calculating relative values of the air pressure, the air flow, the first variable and the second variable for obtaining a plurality of coefficients of a specific equation, (d) determining a third variable and a fourth variable of the heat-dissipating system at a second condition, and (e) replacing the first variable and the second variable of the specific equation with the third variable and the fourth variable respectively for obtaining a second fluid characteristic curve of the heat-dissipating system at the second condition.
