염화칼슘에 의한 라디에이터 엔드 탱크 크랙에 대한 실험적 고찰

Radiator end tank made with PA66 is cracked under very low stress when end tank is exposed to de-icing products especially CaCl₂. This phenomenon is called as ESC (Environment Stress Cracking). The effect of radiator internal and external conditions and tank shape on radiator tank crack by CaCl₂ is studied in this paper. Down flow type radiator is more vulnerable than cross flow radiator. Lots of CaCl₂ accelerate the end tank crack.. And no coolant is in the radiator, no crack was found.
