Cooling of heat dissipating components has become an important topic in the last decades. Sometimes a simple solution is possible, such as placing the critical component closer to the fan outlet. On the other hand this component will heat the air which has to cool the other components further away from the fan outlet. If a substrate bearing a one dimensional array of heat dissipating components, is cooled by forced convection only, an integral equation relating temperature and power is obtained. The forced convection will be modelled by a simple analytical wake function. It will be demonstrated that the integral equation can be solved analytically using fractional calculus.

 Before this paper, the authors have obtained the tangent median relation by using the trigonometric function equation. In this paper, on the basis of the linear positioning solution of one-dimensional equidistant double-base linear array, by proper approximate treatment of the strict solution, and by using the direction finding solution of single base path difference, the sinusoidal median relation of azimuth angle at three stations of the linear array is obtained. By using the sinusoidal median relation, the arithmetic mean solution of azimuth angle at three stations is obtained. All these results reveal the intrinsic correlation between the azimuth angles of one-dimensional linear array.
