Abstract: A freight container for transporting articles at a predetermined temperature is provided with a Peltier element (1) within heat isolating walls. Under control of a control module (2), the Peltier element (1) can be energized by a battery (3) in order to collect or emit heat from/to the inside of the container. The container has an outside supporting frame that keeps the container from collapsing The Peltier element is connected to the supporting frame, via a heat spreader (4), and one or more heat pipes (5) extending through at least one of said insulating walls. Thus, the frame is used emit or collect heat to/from the outside environment of the container. The container, moreover, may comprise photovoltaic means (8) outside the container, on wall panels that are supported by the frame, for converting light into electric energy which can be fed to said Peltier element.
