WebApr 12, 2024 · An electron tube (also known as a 'Vacuum tube', or a 'Valve' ) is a glass or metal enclosure in which electrons move through the vacuum or gas from one metal electrode to another. The vacuum tube is often used to amplify weak currents or act as a one-way valve (rectifier) for electric current. WebVacuum tubes are most effective in colder climates especially where freezing conditions occur. Our Sunrain solar vacuum tubes utilize a copper heat pipe in the center of the tube.Using special aluminum fins, the solar energy is transferred to the heat pipe which contains a small amount of liquid that is under a vacuum.
