Problems solved by technology

[0002] In the prior art, household compact solar water heaters all use conventional all-glass vacuum solar collector tubes, which are glass vacuum tube structures with one end closed and the other open. To increase the light-receiving surface of the conventional all-glass vacuum solar collector tube to receive the sun, the method of increasing the diameter of the inner tube is generally adopted, but the diameter of the inner tube increases, and its capacity increases significantly, thereby increasing the water capacity, but the water capacity The increase in the amount of light does not match the increase in the light-receiving surface, which will cause low water temperature. Under the same solar radiation, the water temperature in the large-size inner tube is lower than the water temperature in the small-size inner tube, which affects the effective external For heat supply, the thermal efficiency is low instead, and the collected solar energy will cause unnecessary loss and cannot be fully utilized in time; It is equipped with an inner tank to reduce the water capacity of the inner tube and increase the water temperature. The disadvantage is that the consumables increase and the production cost increases; in addition, the structure of the inner tube has not changed for decades, and it has always been smooth with a circular radial section. Straight tube shape, its main disadvantage is that the light-receiving surface area and heat transfer area of ​​the inner tube of the vacuum tube are small. Low water pressure, axial bending resistance and sunburst resistance

Embodiment Construction

[0015] Further explain in detail in conjunction with accompanying drawings;

[0016] As shown in Figure 1, there is a vacuum chamber 3 between the outer pipe 1 and the inner pipe 2, the outer surface of the inner pipe 2 has an absorbing coating 4, the positioning steel bracket 5 of the inner pipe 2 is installed in the vacuum chamber 3, and there is The getter 6 has a connection opening 7 at the upper end; the wall of the inner tube 2 is in the shape of a polyhedron.

[0017] As shown in Figure 2, the face of the polyhedral cylinder that the wall of inner tube 2 is is plane, and the radial section of inner tube 2 is equilateral polygonal form, and the intersecting line of adjacent surface is arc transition; The number of faces is preferably more than four sides including four sides; the distance between the peak of the polyhedral cylinder and the inner wall of the outer tube 1 is S, and S must be greater than zero, generally 2 to 6mm. The radial section of the inner tube 2 It ...

Abstract

A special-shaped inner tube all-glass vacuum solar-energy collecting tube is characterized in that: the wall of inner tube (2) is a polyhedral cylinder axially extending along the inner tube (2); the inner and outer faces of the wall of inner tube (2) are relative to the cylinder; the radial section of inner tube (2) is relative to the polyhedral cylinder of the wall of inner tube (2); the face of polyhedral cylinder is plane, or the convex arc or the concave arc. The invention has the advantages in the replace function on the general full-glass vacuum solar-energy collecting tube, to improve the inner and outer faces of inner tube (2), to improve heat adsorption, reduce the water volume of inner tube, improve the heat efficiency and improve the strength, while it can resist the inner water pressure, the axial bend and the explosion. The invention has simple production and low cost.
