PURPOSE:To reduce the amount of oil in an oil room by the radiation effect of rib-shaped radiating plates by positioning these plates at both sides of the oil room with the bases of their fins facing each other and internally connecting the fins and the oil room. CONSTITUTION:A multiple of fins 3 are formed by bending a steel sheet in consecutive corrugation, and the upper and lower portions of the fins are pressed against each other at their respective extremities and by welding or other means they are made oiltight to form rib-shaped radiating plates 4A, 4B. An oil room 12 is made by bending the small flat plate portion between these radiating plates such that the width of its end portion 12a is made narrower than that of the base portion 12b. Choking plates 7 are fixed by welding at the upper and lower faces of the oil room 12, allowing the oil room to be connected internally to the fins of the radiating plates. The oil room's base portion 12b is also connected internally to a tank 1 to form a radiator. |
