Abstract

L'invention porte sur un dispositif de fonte de neige par entrée d'air frais d'un train, le dispositif comprenant un réseau d'entrée d'air (1), un séparateur d'eau de pluie (2), et un dispositif de chauffage. Le séparateur d'eau de pluie (2) est disposé derrière le réseau d'entrée d'air, et est pourvu d'un canal d'entrée d'air de type labyrinthe et de trous de drainage d'eau (206). Le côté, proche du réseau d'entrée d'air, dans le séparateur d'eau de pluie est pourvu du dispositif de chauffage. Lorsqu'une accumulation de neige e est formée au niveau d'une entrée d'air du réseau d'entrée d'air, le dispositif de chauffage peut être démarré pour faire fondre la neige accumulée, et pendant ce temps, le canal d'entrée d'air de type labyrinthe du séparateur d'eau de pluie peut séparer l'eau transportée dans l'air d'entrée en raison de la neige de fusion et évacuer l'eau des trous de drainage d'eau (206). Le dispositif élimine la résistance d'entrée d'air, assure le volume d'air d'entrée d'un climatiseur, empêche également l'eau de la neige d'entrer dans un système de climatisation, et assure le fonctionnement du système de climatisation d'un train dans les conditions de travail de conditions météorologiques de tempête de neige et de basses températures. L'invention concerne en outre un train de chemin de fer équipé du dispositif de fonte de neige par entrée d'air frais.
