A cooling fan (100) of the present invention has a thermal fuse terminal (60) that forms an arc-shaped groove (65A) and a thermal fuse (50) having a contact pin (50-1). A contact portion formed by fitting the contact pin (50-1) to the arc-shaped groove (65A) concentrates conductive heat of radiant heat and the conductive heat generated in the thermal fuse terminal (60) when the contact portion is heated to a high temperature. The concentrated conductive heat is rapidly transmitted to the thermal fuse (50), and the thermal fuse (50) of a heat conduction type resistor (1) is quickly opened. In a situation such as restraint on a motor (100-1), an effective fail safety operation may allow prevention of damage to parts due to radiant heat, a reduction in heat damage, and securement of customer safety, and in particular, when motor conditions are limited in a low temperature zone, the delay of thermal fuse disconnection can be greatly reduced, thus securing robustness to the most important safety. 본 발명의 냉각팬(100)은 접점 핀(50-1)을 구비한 써멀 퓨즈(50)와 호형상 안착홈(65A)을 형성한 써멀 퓨즈 단자(60)를 갖추고, 접점 핀(50-1)이 안착홈(65A)에 끼워져 형성하는 접합부위가 고온 상승 시 써멀 퓨즈 단자(60)에서 발생되는 복사열과 전도열 중 전도열을 집중시키며, 집중된 전도열이 써멀 퓨즈(50)로 신속히 전달됨으로써 써멀 퓨즈(50)의 신속한 단락이 일어나는 열전도형 레지스터(1)를 갖춤으로써 모터(100-1)의 구속과 같은 상황에서 효과적인 FAIL SAFETY 작동으로 복사열에 의한 부품 소손 방지, 열해 개선, 고객 안전성 확보가 가능하고, 특히 저온 지역에서의 모터 구속 조건 시 써멀 퓨즈 단락 지연을 크게 단축함으로써 가장 중요시 되는 안전에 대한 강건성이 확보되는 특징을 갖는다.
