Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables efficient maintenance and heat dissipation in high-density energy conversion systems by allowing easy access to upper containers and ensuring effective airflow, while maintaining structural stability and safety.

Implementation Method 1

second alignment elements for placing a second container on a placement area of the frame structure. The first alignment elements are configured, in one embodiment, as standardized container corners, for example, corner castings, used for cargo containers. Analogously, the second alignment elements are configured, in one embodiment, in a shape that enables the standardized container corners to be arranged in an aligned and fixed manner, for example, as so-called twistlocks.

Methodology Applied
Scientific EffectMechanical Fastening: Mechanical Fastener

Implementation Method 2

A height of the platform between 30 cm and 1 m can generally ensure sufficient heat dissipation. A further improvement in heat dissipation from the energy conversion system can be achieved in that the standing area is formed by inserting base plates in the form of load gratings into the frame structure. Since load gratings are air-permeable, air exchange is also ensured in the vertical direction.

AI summary

The disclosure relates to a platform for the space-saving formation of an energy conversion system. In this, containers are stacked one above the other as housings of components of the energy conversion system with the platform arranged between the containers, wherein the platform has a frame structure which has, on a first side, first alignment elements for placing the platform on a first container and, on a second side, opposite the first side, of the frame structure, second alignment elements for placing a second container on a placement area of the frame structure. The first and second alignment elements are arranged in such a way that they result in an arrangement, which is laterally centered and vertically spaced apart by a height (H) of the platform, of the second container above the first container, wherein the frame structure forms a standing area, which circumferentially surrounds the placement area and is walkable by persons, as access to the second container. An energy conversion system can be designed as a stack of at least two containers as housings of components of the energy conversion system, between each of which containers such a platform is arranged.
