Abstract

This invention discloses a solar heated vacuum tube providing heated air for multi-purpose applications.

Description

Solar Heated Vacuum Tube
Description of the Invention
The invention is described with the hel p of the drawings described below.
Description of the Drawings
Figure 1 is cross sectional view of the vacuum tube connected to a n oven. A: Vacuum tube, B: Air inlet to vacuum tube, C: Heated air outlet (with a fan), F: Trays holding material to be dried, G: Oven, K: Heated air enteringthe oven form the vacuum tube
Figure 2 is a preferred embodiment of the invention where the vacuum tube is kept in the focal point of a concave mirror's focal point. A: Vacuum tube, J: Incident radiation waves on the mirror, K: Heated air emanatingfrom the vacuum tube
Figure 3 is a picture of the invention where the vacuum tube in the focal point feeds a n oven with heated air.
Background and Description of the Invention
Hot air is used to for many drying applications, specifically in dry food industry. Conventionally, dry air is entered by electricity power, a burning gasses or fire wood.
Vacuum tubes have the capability to hold its' inside temperaturedue to its' construction characteristics.
In this invention, a vacuum tube is heated by radiation energy of the sun and the generated hot air inside the vacuum tube is channeled to an oven where dry air is needed. In a preferred embodiment, the vacuum tube is placed in the focal point of a concave mirror to enhance the heating process.
As shown in Figure l and Figure 2, the vacuum tube is placed in the focal point of the concave mirror. When the radiation waves are incident on the mirror surface, those rays reflected to the focal point. The heat collected at the focal point heats up the vacuum tube. The generated hot air inside the vacuum tube is channeled to the oven where hot air is needed.
To enhance performance, the mirror can be coupled with a solar tracking system so that the mirror is always facingthe sun.

Claims
