Abstract
The present invention discloses a refrigerated container with an anti-collision plate. The refrigerated container comprises a side wall having an inner side plate and an outer side plate. The anti-collision plate is arranged at a lower portion of a surface of the inner side plate facing the outer side plate. The anti-collision plate is formed with depressed portions and protruded portions at its upper edge. The depressed portions and the protruded portions may be in shape of rectangle, triangle, trapezoid or wave. By arranging depressed portions and protruded portions at the upper edge of the anti-collision plate, the conventional linear type abrupt change of cross-section of the inner side plate at the upper edge of the anti-collision plate becomes a curvilinear type abrupt change of cross-section, and thus the extent of concentration of stress of the inner side plate at the abrupt change of cross-section is significantly lowered. Consequently, the strength and rigidity of the inner side plate are increased, thereby increasing a damage resistance of the side walls against the disadvantageous external force and improving the safety performance and service life of the refrigerated container.
