PURPOSE:To support a good heat conductor box in a stable manner and facilitate insertion work of said good conductor box into an insulation box by inserting said good conductor box into said insulation box, allowing the good conductor box to slide on a rail member and screwing a front flange of the good conductor box into its fixed flange. CONSTITUTION:A good heat conductor box 3, on which insulation sheets 36 made of expanded polyethylene or the like are adhered on the surface of a cooled air passage side of a top board A, is inserted into an insulation box 1 from its front opening. On the other hand, when an outward-faced front flange 3F formed on the periphery edge of the front opening of an upper good conductor box 3 is placed into contact with a fixed flange 37 fixedly adhered on an inner side peripheral edge of an opening section of the insulation box 1 on the same plane with the front of U-shaped front angle 24, the insertion of the good conductor box is controlled. Under this state, the front flange 3F is screwed into the fixed flange 37 by way of a gasket in an enclosed manner, thereby finishing the fixing of the good conductor box 3. Similarly, a lower good conductor box 4 is inserted into the insulation box 1 from its front opening. |
