Abstract

En la presente descripción se describe una empaquetadura para montar en un vástago de maquinaria. De acuerdo con un aspecto, el alojamiento de empaquetadura define una abertura central para la inserción de un vástago de maquinaria móvil con un conducto hueco que rodea la abertura central para formar un trayecto para el flujo de un refrigerante fluido. El conducto se proporciona con una abertura de puerto de entrada de fluido y una abertura de puerto de salida de fluido sobre la superficie exterior del alojamiento de empaquetadura, y se forma mediante un único conducto o mediante una pluralidad de conductos obtenidos a través del proceso de fabricación aditiva y conectados en serie o en paralelo para enrollarse alrededor de la abertura central.
