PURPOSE: A heater for air conditioners of vehicles is provided to improve heating efficiency of the heater by the integrated formation of a radiating unit. CONSTITUTION: A heater for air conditioners of vehicles comprises a plate-shaped positive temperature coefficient (PTC) element heating unit (210), and a plate-shaped radiating unit (220). The plate-shaped radiating unit is arranged in the upper or lower side of the PTC element heating unit relative to the fluid transfer direction, receives the heat from the PTC element heating unit, delivers the same to the fluid, and is arranged in the PTC element heating unit in parallel. The angle which is formed by a perpendicular line of the radiating unit and the transfer direction of fluid is less than 90 degrees. |
