The present invention relates to a heater device of an electric vehicle. The heater device of an electric vehicle comprises: a circulation pump for circulating supplied water; a heating element for heating the circulated water; a water temperature sensor for measuring the temperature of the water heated by the heating element; a supply joint for distributing the water heated by the heating element to a plurality of heaters for supplying the hot water into a vehicle; an inflow joint for collecting cold water cooled by the plurality of heaters and feeding back the collected cold water to the circulation pump; a controller for controlling the heating element for the temperature measured by the water temperature sensor to satisfy a set temperature value; and a power supply unit for supplying electricity to a resistor. In addition, a heat exchange portion is provided with the plurality of heating elements, and provided with a heat exchange pipe portion surrounding the plurality of heating elements.

    본 발명은,공급된 워터를 순환시키는 순환펌프;와 상기 순환되는 워터를 가열하는 발열체;와 상기 발열체에 의해 가열된 온수의 온도를 측정하기 위한 수온센서;와 상기 발열체에 의해 가열된 온수를 차내에 공급하는 복수의 히터에 분배하는 공급조인트;와 상기 복수의 히터에서 냉각된 냉수를 수집하여 상기 순환펌프에 피드백하는 입수조인트;및 상기 수온센서에서 측정된 측정온도가 설정온도값을 만족하도록 상기 발열체를 조절하는 제어부;와 상기 저항기에 전기를 공급하는 전원부;를 포함하여 이루어지는 것을 특징으로 하는 전기차량의 히터장치에 관한것이다. 또한 상기 열교환부에는 상기 발열체가 복수개 구비되고 상기 복수의 발열체를 감싸는 열교환배관부가 구비되는 것을 특징으로 하는 전기차량의 히터장치에 관한것이다.
