Abstract
The utility model relates to a reflection condensation type solar vacuum tube which comprises an outer tube and an inner tube. The inner tube is installed inside the outer tube. A vacuum layer is formed between the outer tube and the inner tube. The inner tube is a transparent glass tube. The face, facing the sun, of the outer tube, is provided with a transparent arc-shaped plate, and the face, not facing the sun, of the outer tube, is provided with a reflection arc-shaped plate. The transparent arc-shaped plate and the reflection arc-shaped plate are of an integrated structure. The inner surface of the reflection arc-shaped plate is provided with two arc-shaped mirror reflection areas. An electric heating area is reserved between the two arc-shaped mirror reflection areas. Electric heating pieces are arranged inside the electric heating area and connected with power supply equipment. According to the reflection condensation type solar vacuum tube, sunlight entering the outer tube is reflected into the inner tube through the reflection arc-shaped plate for heating water, improves heat-collecting efficiency and acts together with the sunlight directly shining on the outer wall of the inner tube, rising speed of the environmental temperature inside the inner tube is accelerated, and therefore the heat-collecting efficiency is improved. Moreover, the electric heating pieces can provide electric heating energy when the sunlight is not enough and can be used for thawing snow on snowy days so that the vacuum tube can work normally.
Description
Technical field
The utility model relates to the solar energy vacuum tube technical field, especially a kind of reflecting condensation formula solar energy vacuum tube.
