PROBLEM TO BE SOLVED: To reduce the occurrence of draft resistance and to increase a circulation airflow by a method wherein a plate to smooth guide air in a chamber over the upper surface of an end wall is arranged at a corner part comprising the upper surface of the end wall and the inner surface of an inside outside partition wall and air in the chamber lowering through a draft trunk is smoothly guided over the upper surface of the end wall. SOLUTION: Plates 50 and 50 to smoothly guide air in a chamber over an upper surface F are arranged at a corner part comprised by the inner surface of an inside output partition wall 41 and an upper surface F of an end wall 1B and formed at the lower parts of a draft trunk 48 and 49. A corner part between the upper surface of a floor wall 1A of a container 1 and the inner surface of an end wall 1B forms a smooth curved surface 51. Air in the chamber lowering through the draft trunks 48 and 49 during operation of a refrigerating unit 100 smoothly convert a direction to a horizontal in such a manner to be guided by the plate 50 and the smooth curved surface 51 and returns in a chamber through the gap of a T-rail 43 and is raised through the gap of a cargo 35. This constitution lowers draft resistance and increases a circulation airflow. |
