DETAILED DESCRIPTION

[0036] A transport container for transporting temperature-sensitive transport goods, comprises an interior for receiving the transport goods and an enclosure enclosing the interior and comprising a heat insulation, wherein at least one latent heat accumulator and at least one active temperature-control element are provided for controlling the temperature in the interior, characterized in that the enclosure is designed as a multilayer enclosure, wherein the heat insulation, the latent heat accumulator, and optionally the active temperature-control element, are configured as mutually separate, superimposed layers of the enclosure.

[0037] A transport container can include at least two, in particular all three, layers superimposed in heat-conducting connection with one another. In particular, with respect to at least two of the superimposed layers, in heat-conducting connection comprises full-surface contact as between such at least two of the superimposed layers.

[0038] In a transport container, the latent heat accumulator layer (9), the insulation layer (8), and optionally the active temperature-control layer (7), can each enclose the interior completely.

[0039] A transport container can comprise a polygonally shaped structure, such as a parallelepiped. For instance, transport container can comprise a rectangular parallelepiped structure in which the enclosure comprises six walls. Each of which walls can be designed with multiple layers, e.g., at least three layers comprising a latent heat accumulator layer, an insulation layer and an active temperature-control layer.

[0040] A transport container can include an access door. A wall can be designed as door. For example, with a parallelepiped structure, one of the six walls can be designed as a door.

[0041] A transport container can include an active temperature-control layer configured for converting electric energy into heat to be released or absorbed.

[0042] A transport container can include an active temperature-control layer comprising Peltier elements, a heat exchanger cooperating with a thermodynamic cycle process, in particular a compression refrigerating machine, or magnetic cooling.

[0043] A transport container can include the insulation layer disposed between the further outwardly disposed temperature-control layer and the further inwardly disposed latent heat accumulator layer.

[0044] A transport container can include a insulation layer disposed further outwards than the temperature-control layer and the latent heat accumulator layer.

[0045] A transport container can include a temperature-control layer disposed between the external insulation layer and the latent heat accumulator layer.

[0046] A transport container can include a latent heat accumulator layer disposed between the external insulation layer and the temperature-control layer.

[0047] A transport container can include an energy distribution layer comprising a highly heat-conductive material arranged within the energy distribution layer for uniformly distributing thermal energy acting on the container from outside. The energy distribution layer is preferably disposed further outside than the latent heat accumulator layer.

[0048] A transport container can include a further energy distribution layer. For example, one energy distribution layer can be disposed on either side of the latent heat accumulator layer.

[0049] FIG. 1 depicts a parallelepiped-shaped transport container 1 whose walls are denoted by 2, 3, 4, 5 and 6. On the sixth side, the transport container 1 is shown open to visualize the layered structure of the walls. The open side can, for instance, be closed by a door having the same layered structure as the walls 2, 3, 4, 5 and 6. All of the six walls of the transport container 1 have identical layered structures. The layered structure comprises an outer layer 7, an intermediate layer 8, and an inner layer 9.

[0050] According to a first variant, layer 7 is an active temperature-control element, e.g. a layer provided with Peltier elements, layer 8 is an insulation layer, and layer 9 constitutes a latent heat accumulator layer.

[0051] According to a second variant, layer 7 is an insulation layer, layer 8 is an active temperature-control element, and layer 9 is a latent heat accumulator layer.

[0052] According to a third variant, layer 7 is an insulation layer, layer 8 is a latent heat accumulator layer, and layer 9 is an active temperature-control element.
