Title: SOLAR RECEIVER USING HEAT PIPES AND GRANULAR THERMAL STORAGE MEDIUM
Abstract:
A receiver for a concentrating solar power plant uses heat pipes to transfer thermal energy to a heat transfer medium in a chamber. An evaporation zone of each of the heat pipes is outside the chamber, and the heat pipes extend through a front wall of the chamber so that their condensation zones are inside the chamber. The heat transfer medium substantially surrounds the heat pipes. In some installations, the total surface area of the heat pipes within the heat transfer medium may be larger than the projected area of the ends of the plurality of heat pipes receiving solar radiation onto the plane of the aperture of the receiver. In some installations, the heat transfer medium is a granular heat transfer medium, and the heat transfer medium and the heat pipes form a moving bed heat exchanger.
