Innovative Heat Sink / Heat Storage Component Made of Aluminum Foam and Phase Change Material (PCM)
The continuous growth of the demand for primary energy, predominantly derived from fossil sources, is causing severe environmental problems. However, over two-thirds of this energy is immediately dissipated as waste heat, released into the environment without any utilisation, such as during electricity production, combustion engines, and metallurgy. Paradoxically, instead of harnessing such excess heat, additional primary energy sources are used for heating purposes in buildings. Furthermore, the waste heat might pose a high risk of overheating, resulting in frequent failure of high-powered electrical and electronic devices.
This technology addresses the issue by capturing and storing the heat in a special heat sink or battery. The stored energy can be easily transported (by land transport without pipelines) and utilised at specific locations when required. The waste heat with lower temperature can be re-used, leading to substantial savings in primary energy. When integrated into the packaging of heat-generating devices (e.g., battery chargers, power electronics, etc.), excess heat is efficiently absorbed without a significant increase in device temperature. The absorbed heat is gradually emitted into the surroundings as the device's power diminishes. Charging the package with heat can maintain the optimal working temperature during cold season, enhancing the overall performance.
The ideal collaboration partners include manufacturers of thermal batteries, heating or cooling systems, and components that generate high levels of heat, such as chargers and electronic devices. Potential partners also encompass companies involved in the production of waste heat, seeking viable alternatives to supply to suitable customers.
