Abstract

본발명은 자율온도 제어형 고분자 발열전선에 관한 것으로서, 특히 기존의 절연자켓 내부에 별도의 내부절연 쟈켓을 형성하여 자율온도 제어 특성을 향상시킨 고분자 발열전선에 관한 것이다.The present invention relates to an autothermal temperature controlled polymer heating wire, and more particularly, to a polymer heating wire which improves autonomous temperature control characteristics by forming a separate internal insulation jacket inside an existing insulating jacket.

즉, 본발명은 종래의 덤벨형과 유사한 형태로 성형된 발열체 외부에 발열체를 이루는 고분자 재료의 동일하거나 비슷한 열팽창 특성을 갖는 고분자 재료로 내부절연 쟈켓을 형성하되, 발열체의 형상이 종래의 플랫형과 유사한 형태로 되게 형성함으로써 내부절연 쟈켓의 팽창과 수축에 의한 기계적인 힘이 발열체에 작용하여 자율온도 제어특성이 향상되도록 한 것이다.That is, the present invention forms an inner insulation jacket with a polymer material having the same or similar thermal expansion properties of the polymer material forming the heating element on the outside of the heating element molded in a similar form to the conventional dumbbell type, but the shape of the heating element is By forming it in a similar form, the mechanical force caused by the expansion and contraction of the inner insulation jacket acts on the heating element to improve the autonomous temperature control characteristic.
