El cálculo matemático exacto del perfil de temperatura y por ende de la eficiencia de la aleta con sección transversal no uniforme implica la solución de una ecuación diferencial de Bessel modificada. En este artículo se presenta e implementa una alternativa de cálculo de las funciones de Bessel modificadas de primera y segunda clase que resultan de resolver la ecuación diferencial y que permite la valoración de la eficiencia de la aleta. Se utilizan cuadraturas de Gauss y de Laguerre para la integración numérica de las funciones modificadas de Bessel de cualquier orden. Esta alternativa puede considerarse como una forma más elaborada y precisa, con respecto a las propuestas convencionales para la solución del problema.
