Abstract: A refrigerated cargo container, comprising no moving parts, for use in transporting temperature sensitive cargoes in aircraft. The container has six insulated walls with an insulated door along part of one of the walls, preferably the container's front wall, to provide for an air-tight container when the door is closed. An insulated bunker, having an insulated wall about a portion of its outer surface and a heat exchange portion along its bottom surface, containing a coolant such as solid carbon dioxide, is located within one of the top corners of the insulated cargo container. An air inlet duct extends along the top wall of the insulated container to one side of the insulated bunker to allow warm air from the interior of the container and the cargo to flow into the inlet duct along the top wall of the container and to pass along the side and bottom of the coolant bunker where the warm air is cooled by the heat exchange portion of the bunker.
