철도차량용 발열시트 제작을 위한 필름형 발열체 발열 성능 평가

초록

In recent years, the application of heated seats has been gradually increasing in railway vehicles to improve passenger convenience. However, in the case of hot wire methods, energy efficiency is low, and there is a risk of fire owing to the corrosion of pyrogen during extended use. Thus, the application of surface heating technology, which is energy-efficient and favorable for face-to-face structures, is gradually expanding. This study assesses the applicability of film-type surface exothermic materials to the manufacture of heating sheets for railway vehicles. The exothermic film is applied to the rear of the plastic sheet used in urban railway vehicles, and the heating performance is quantitatively evaluated based on the applied voltage. The test results confirm that the exothermic film can be a good candidate for heating sheets with excellent heating performance and uniformity.
