  • Publication number: 20200031199
    Abstract: A PTC heater includes PTC heater parts in which heater rods and radiation fins are alternately arranged. A frame is formed along a circumference to support the PTC heater parts. IGBT elements are installed on the frame and selectively apply a battery current to each of the heater rods to adjust the heat generation amount of the heater rods. A control module is installed on the frame and controls the IGBT elements to adjust the heat generation amount of the heater rods according to a target temperature value. A heat sink is installed on the frame, is connected with the IGBT elements for heat-exchange, is formed to pass the PTC heater parts in the horizontal direction and radiate heat of the IGBT elements through the flowing air inside the air conditioning case.
