The present invention relates to a water heater device for an electric vehicle having a carbon-printed heating means. According to the present invention, a heating unit made of a metal material having high thermal conductivity is formed on the bottom surface of a chamber formed in a sealed zigzag shape to allow water introduced through an inlet to be moved, and a carbon-printed layer formed by printing carbon particles is installed in a lower surface of the heating unit. Therefore, water can be quickly heated while heat generated from the carbon-printed layer is transferred to the chamber through the heating unit during movement of the water in the chamber. In addition, the carbon-printed layer, in which carbon particles are printed by the thickness of several μm is used as a heating means such that the volume of the heating means can be remarkably reduced, and the size of the water heater device can also be remarkably reduced.

    본 발명은 카본이 인쇄된 발열수단을 구비한 전기차용 워터 히터장치에 관한 것으로서, 더욱 상세하게는 유입구로 유입된 워터가 이동할 수 있도록 밀폐된 지그재그 형태로 형성되는 챔버의 바닥면에 열전도성이 높은 금속재질로 이루어지는 가열부를 형성하고, 가열부의 저면에 카본입자를 인쇄하여 형성한 카본인쇄층을 설치하여 구성하므로서, 챔버 내부를 워터가 이동하는 동안 카본인쇄층에서 발생되는 열이 가열부를 통해 챔버로 전달되면서 빠른시간이 워터를 가열할 수 있으며, 발열수단으로서 카본입자를 수 ㎛ 의 두께로 인쇄한 카본인쇄층을 이용하게되므로 발열수단의 부피를 현저히 감소시킬 수 있게됨은 물론 워터 히터장치의 크기 또한 현저히 줄여줄 수 있도록 한 카본이 인쇄된 발열수단을 구비한 전기차용 워터 히터장치에 관한 것이다.
