Title:
ENERGY CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/056074
Kind Code:
A1
Abstract:
An energy conversion device equipped with a conduit unit (10), an input unit (20), and an output unit (30). The conduit unit is filled with a medium capable of undergoing a gas-liquid phase change, and is able to transmit acoustic energy by means of the medium. The input unit is provided in the conduit unit, is able to receive an input of heat energy, and converts the heat energy to acoustic energy. The output unit is provided in the conduit unit and converts the acoustic energy to another type of energy. The input unit is provided with regeneration units (23, 24, and 25) that are capable of exhibiting a temperature gradient on the basis of the input of heat energy, and that cause the medium to change to a gas phase and a liquid phase on the basis of the temperature gradient. The regeneration units are provided with medium retention members (23c, 24b) that are able to retain and discharge the medium.
