Abstract

Estructura de carcasa para una turbomáquina, que rodea al menos de forma anular un canal de flujo (14) en el que se disponen álabes de guía y rotor, en donde la estructura de carcasa presenta una pared interior que delimita el canal de flujo (2) y una pared exterior posterior opuesta al área circundante (I), en donde separado de la pared interior se forma al menos un canal de aire de refrigeración (6) que presenta al menos un elemento de guía de aire (5, 15), en donde el canal de aire de refrigeración circula exclusivamente separado de la pared interior, caracterizada porque en el lado radialmente exterior de la pared interior está dispuesta una chapa de protección térmica (3) y entre la chapa de protección térmica y el canal de aire de refrigeración está dispuesto un aislamiento (4).
