An object of the utility model is to provide a can cushion vacuum tube expansion internal stress can directly carry out the bi-pass solar vacuum tube of taking the calabash knot that heats to the medium.
In order to solve the technical problem, the invention provides a two-way solar vacuum tube with a gourd tie, which is characterized by at least comprising a glass outer wall, a glass inner wall, a vacuum cavity, a sealing blind end and a gourd tie, wherein the vacuum tube is made of all-glass materials, two ends of the glass inner wall and two ends of the glass outer wall are sealed to form the sealing blind end, the vacuum cavity is formed between the glass inner wall and the glass outer wall, and the vacuum tube forms a completely through cavity along an axis.
Optionally, the inner glass wall is treated to form a selectively absorbing coating.
Optionally, the gourd knot can buffer or even eliminate internal stress generated by inconsistent expansion of the inner glass wall and the outer glass wall, and the possibility of damage to the vacuum tube due to the internal stress is reduced.
Alternatively, the gourd knots can be singly arranged to form a single gourd knot, and a plurality of the gourd knots can be arranged to form a gourd knot string.
Optionally, the gourd knot is located on the inner wall of the glass, and the gourd knot and the inner wall of the glass form a whole.
Optionally, the gourd knots can be protruded inwards from the inner wall of the glass, can be protruded outwards from the inner wall of the glass, and can be protruded bidirectionally from the inner wall of the glass.
Optionally, the cucurbit junction is in a shape of a plurality of bulges such as a sine curve, a cosine curve, a parabola and a triangle, or a combination of shapes.

Marking: 1. the glass comprises a glass outer wall, 2. a glass inner wall, 3. a vacuum cavity, 4. a sealed blind end, 5. a gourd knot, 6. a single gourd knot, 7. a gourd knot string, 8. a gourd knot inner bulge, 9. a gourd knot outer bulge and 10. a gourd knot bidirectional bulge.
Detailed Description
The technical solutions in the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
The utility model provides a two-way solar vacuum tube of area calabash knot, the vacuum tube includes glass outer wall 1, glass inner wall 2, vacuum cavity 3, sealed cecum 4, calabash knot 5 at least, the vacuum tube is full glass material, and the sealed cecum 4 that forms in the both ends of glass inner wall 2 and glass outer wall 1's both ends, forms vacuum cavity 3 between glass inner wall 2 and the glass outer wall 1, the vacuum tube forms the cavity that link up completely along the axis.
The outer surface of the glass inner wall 2 is treated to form a selective absorption coating, and heat is transferred to substances in the cavity through selective absorption of sunlight.
Because the selective absorption coating on the glass inner wall 2 can absorb solar energy, the temperature of the glass inner wall 2 is far higher than that of the glass outer wall 1 in the operation process, so that the glass inner wall 2 and the glass outer wall 1 expand unevenly, and internal stress capable of damaging a vacuum tube is formed. The gourd knot 5 can buffer and even eliminate internal stress generated by inconsistent expansion of the glass inner wall 2 and the glass outer wall 1, and the possibility of damage of the vacuum tube due to the internal stress is reduced.
The gourd knots 5 can be singly arranged to form 6 single gourd knots, and also can be arranged in a plurality of rows to form a gourd knot string 7.
The gourd knots 5 are positioned on the glass inner wall 2, the gourd knots 5 are obtained by carrying out corresponding process processing on the glass inner wall 2, and the gourd knots 5 and the glass inner wall 2 form a whole.
The gourd knots 5 can be formed into gourd knot inner bulges 8 by the inward bulges of the glass inner wall 2, the gourd knots 5 can also be formed into gourd knot outer bulges 9 by the outward bulges of the glass inner wall 2, and the gourd knots 5 can also be formed into gourd knot bidirectional bulges 10 by the bidirectional bulges of the glass inner wall 2.
The gourd knot 5 may be in the shape of a plurality of convex shapes such as sine curve, cosine curve, parabola shape, triangle shape, etc., or a combination of a plurality of shapes.
