PURPOSE:To eliminate any drop in a flow velocity of running air at the time of passing through a radiator as well as to aim at a rise of heat exchanger effectiveness, by setting up a cooling fin of the radiator so as to cause a lot of ventilating holes to be formed by this cooling fin to become parallel with the running air. CONSTITUTION:A radiator 20 is a parallelogram of long lengthwise in side from tilting an upper part of a radiator core 20c frontward, and it is formed so as to cause its vertical lines to become parallel with running air, while a cooling fin 20d is set up inside this radiator core 20c. A radiator hose 18 taking in cooling water becoming high temperature after cooling an engine is connected to an upper part of the radiator 20, while another radiator hose 19 feeding the engine with the cooling water becoming low temperature after heat exchange with the running air at the radiator 20 is connected to the lower part, respectively. And, at the time of passing through a lot of ventilating holes, it receives no resistance of the cooling fin 20d and its direction is not varied at all so that its flow velocity is in no case dropped. |
