Abstract
La présente invention concerne un revêtement non-collant (1), qui empêche l'accumulation d'humidité gelée et qui est appliqué à des parties exposées à l'extérieur de systèmes de chauffage et de refroidissement où de la glace ou d'autres humidités gelées peuvent s'accumuler et gêner l'efficacité opérationnelle du système. Les tubes d'échange de chaleur (2) et les ailettes sont inclinés ou incurvés vers le bas. Un moyen ou une conception de tube ou de plaque capillaire optionnel est utilisé, laquelle plaque (12) possède une surface (17) extérieure (12) composée d'au moins des pointillés, des saillies, des tranchées et une surface plate. Un logement de coque protectrice en option (5) peut être formé pour offrir un effet de section contractée. L'invention concerne aussi un ventilateur électrique optionnel (9) pour améliorer le flux d'air pour l'échange de chaleur, un vibrateur électrique optionnel (10) pour mieux empêcher l'accumulation d'humidité gelée et une base inclinée vers le bas (8) pour éloigner l'humidité gelée qui tombe de l'équipement d'échange de chaleur.
