The present invention relates to an electrothermal heater. By improving a structure of the heater, a cooling efficiency of a heat sink for cooling an insulated gate bipolar transistor (IGBT) element can be increased, and at the same time the present invention is able to prevent a heat exchange loss of a heater due to installation of a frame of the heat sink and a decrease in a blowing amount inside a vehicle, despite the fact that the heat sink is installed in the frame of the heater. To this end, the present invention comprises: a frame; and a control portion for controlling a heat generation amount of a heating portion installed inside the frame. In addition, the heat sink for cooling the control portion is included in which the heat sink is embedded in the frame while being connected to the control portion to emit heat of the control portion. Also, an air passing means is further provided to form a passage of air on the side of the frame and the heat sink so that the air on an upstream side of the electrothermal heater can be heat-exchanged while passing through the frame and the heat sink built in the frame.

    본 발명은 전열히터에 관한 것으로서, 히터의 구조를 개선함으로써, IGBT 소자 냉각용 히트싱크의 냉각효율을 높일 수 있음과 동시에, 히트싱크를 히터의 프레임에 설치함에도 불구하고, 히트싱크의 프레임 설치로 인한 히터의 열교환 손실과, 차실내의 송풍량 저하를 방지할 수 있도록 하는 것을 목적으로 한다. 이러한 목적을 달성하기 위하여 본 발명은, 프레임과 프레임의 내측에 설치되는 발열부와 발열부의 발열량을 제어하는 제어부를 포함하는 전열히터에 있어서, 제어부를 냉각시키기 위한 히트싱크를 포함하며; 히트싱크는, 제어부와 연결된 상태에서 프레임에 내장되어, 제어부의 열을 방출하고; 전열히터의 상류측 공기가, 프레임과, 프레임에 내장된 히트싱크를 통과하면서 열교환될 수 있도록, 프레임과 히트싱크측에 공기의 통로를 형성하는 공기통과수단을 더 구비한다.
