Abstract

The ball has a casing made of steel, and including two parts (100a, 100b). A ball opening (102) is provided in a part (102a) for incidence radiation. A ceramic-insulation layer (106) is provided on a side of a steel hopper (104). An inner mass (108) is arranged below the steel hopper, and is made of hard metal such as tungsten-carbide, titanium or platinum. A focal point-interception surface (110) is arranged at an upper side of the mass. The ball is heated by an optical lens i.e. Fresnel-lens. A focal point of the Fresnel-lens is focused by the opening on a mass core.

Description

Die Erfindung ermöglicht es, Sonnenenergie optisch zu bündeln, um solare Hitze in einem Metall-Ball für einen längeren Zeitraum zu speichern.The Invention allows to visually bundle solar energy to store solar heat in a metal ball for a long period of time.

Der Brennpunkt einer Fresnel-Linse wird durch eine Ball-(Kugel-)Öffnung auf den im Inneren des Balles befindlichen Massekern fokussiert.Of the Focus of a Fresnel lens is through a ball (ball) opening focused in the interior of the ball located in the ground core.

In wenigen Minuten erreicht der innere Kern die höchste Temperaturkonzentration, so dass das Speichermedium, z. B. Salz schmilzt. Bei Kristallisierung (Gefrieren) des Speichermediums (u. a. Salz) wird eine hohe Hitze abgegeben. Auf diese Weise ist der Ball optimal als Wärmetauscher zu nutzen.In a few minutes, the inner core reaches the highest temperature concentration, so that the storage medium, z. B. Salt melts. In crystallization (Freezing) the storage medium (including salt) becomes a high heat issued. In this way, the ball is optimal as a heat exchanger to use.

Die Ballgröße, die Wandstärke, die innere Masse und das Speichermedium sind je nach Anforderung (Parameter) zu optimieren.The Ball size, the Wall thickness, the internal mass and the storage medium are according to the requirement (Parameter) to optimize.

Der Ball ist immer wieder aufladbar und bietet aufgrund seiner Form und Beweglichkeit vielfältige, thermische Anwendungen.Of the Ball is always rechargeable and offers due to its shape and mobility diverse, thermal applications.
