PURPOSE: A heat exchanger for vehicle is provided to improve heat radiation performance by setting a ratio of an internal heat exchange area and an external heat exchange area to a predetermined value. CONSTITUTION: A heat exchanger for vehicle comprises a plurality of tubes(111), a core, and a main tank. The plural tubes are arranged in parallel to an air flow direction. A heat exchange medium flows within the tube. The core includes a pin(112) interposed between the neighboring tubes. The main tank is located in top and bottom of the core, and connected to the tube. In one side of the main tank, an outlet pipe and an inlet pipe in which the heat exchange medium flows in and out are formed. |
