El valor del coeficiente de transferencia de calor depende de varios factores, como las propiedades del fluido, su velocidad, la geometr\u00eda y el estado de la superficie.

Las superficies microsc\u00f3picamente irregulares introducen burbujas de aire en la interfaz, mientras que una presi\u00f3n insuficiente genera una alta resistencia interfacial. Estos factores aumentan la resistencia interfacial entre la fuente de calor, el material TIM y el disipador t\u00e9rmico.<\/p>\n<p>La resistencia de contacto se convierte en un factor importante cuando la capa de material de interfaz t\u00e9rmica (TIM) es muy delgada. La norma ASTM D5470 considera el efecto de la presi\u00f3n de contacto y las caracter\u00edsticas de la superficie de la muestra en las mediciones de las propiedades de transmisi\u00f3n t\u00e9rmica.

Las almohadillas de separaci\u00f3n blandas se comprimen contra superficies irregulares, mientras que un TIM m\u00e1s duro ofrece mayor estabilidad dimensional. Por lo tanto, la compresibilidad, la dureza y las propiedades de recuperaci\u00f3n son tan importantes como la conductividad t\u00e9rmica.<\/p>\n<p>Los ciclos t\u00e9rmicos pueden provocar la expansi\u00f3n y contracci\u00f3n de las piezas adyacentes. Un material de interfaz t\u00e9rmica (TIM) adecuado mantiene el contacto sin sufrir grandes deformaciones permanentes ni generar tensiones mec\u00e1nicas.

En capas de TIM uniformes, la resistencia est\u00e1 determinada por el espesor, la conductividad t\u00e9rmica y el \u00e1rea de contacto. Una capa delgada de TIM disminuye la resistencia volum\u00e9trica siempre que existan peque\u00f1os espacios entre las superficies de contacto.<\/p>\n<p>Las separaciones m\u00e1s grandes requieren capas TIM gruesas para asegurar que el contacto se mantenga en la interfaz.
