Abstract

PURPOSE:To obtain the light small-sized oil tank having large mechanical strength and a large radiant area without increasing the thickness of finny projecting sections by using a corrugated radiator plate in which flanges are mounted at both ends of a continuous finny projecting section group formed by bending an iron plate in corrugated shape. CONSTITUTION:The thin steel plate 1 is bent and the projecting sections 1a are formed continuously at regular intervals, and the flanges 1b are mounted at both ends. The corrugated radiator plates 11, 12 are opposed and used as short side side walls, a corrugated radiator plate 13 is employed as the long side side wall of the bottom, a slat- shaped side wall 14 is arranged, and mutually adjacent end sections are welded one another in an oil-tight manner by flange sections. Both sides of the short side side walls 11, 12 are positioned at sections more external than the base sections 13a, 14a of the long side side walls 13, 14, bushings 5 are mounted to the base section 14a of the side wall 14, and a cable duct 6 is set up. According to this constitution, finny projecting sections 25 can also be formed inside the cable duct, the external form can be reduced by the fixed quantity of radiation, and the tank can correspond to the inner pressure of the tank without increasing plate thickness and can be lightened.
