Abstract
The utility model discloses a double corrugated vacuum solar heat collection pipe. An inner layer or an outer layer of a covering glass pipe is divided into equal parts, each equal part is a longitudinal strip-shaped concave face or a convex face, the outer layer or the inner layer of an inner glass pipe is divided into corresponding equal parts, and each equal part is a longitudinal strip-shaped convex face or a concave face. According to the double corrugated vacuum solar heat collection pipe, the inner structure of the heat collection pipe is changed on the basis that the external dimension of a vacuum pipe is not changed, strip-shaped corrugations are increased, therefore the strength, the vacuum degree and the heat collection quantity of the heat collection pipe are effectively increased, and heat loss is reduced.
Description
Affiliated technical field
The utility model relates to a kind of solar water heating system, particularly a kind of thermal-collecting tube of solar water heater.
Background technology
Thermal-collecting tube is one of solar water heating system critical component.At present, the employed thermal-collecting tube of solar water heating system mainly is comprised of common annular inner glass tube and cover glass tube, heat-collecting pipe vacuum degree and structural strength are general, and in the restriceted envelope of heat-collecting pipe vacuum interlayer, the area of solar selective absorbing coating is a fixed value, therefore the heat-collecting capacity of ordinary construction thermal-collecting tube is relatively fixing, and vacuum is general, and certain heat loss is arranged.
The utility model content
The utility model purpose is to overcome the deficiencies in the prior art, and a kind of Effective Raise vacuum is provided, and reduces heat transmission, reduces the dual damascene vacuum solar collector tubes of heat loss.
The technical scheme that its technical problem that solves the utility model adopts is: be divided into equal portions at cover glass tube nexine or skin, every equal portions are longitudinal strip concave surface or convex surface, inner glass tube skin or nexine are divided into corresponding equal portions, and every equal portions are longitudinal strip convex surface or concave surface.
The equal portions value of described cover glass tube nexine or skin, inner glass tube skin or nexine is 8-100.
The utility model reduces heat and transmits and heat loss in order to increase heat-collecting pipe vacuum degree, structural strength and heat-collecting capacity, has adopted the dual damascene thermal-collecting tube of interior glass bellows and cover glass bellows.The cover glass tube concave surface has scattering process to light, and the inner glass tube convex surface scribbles solar selective absorbing coating, and the convex surface projection has effectively increased the area of solar selective absorbing coating.Many longitudinal stripes structurally can effectively increase the intensity of thermal-collecting tube simultaneously; The bellows strength increase so that the vacuum of bellows can further increase, transmits and minimizing is hot, and thermal loss is reduced.
The utility model changes the thermal-collecting tube internal structure on the basis of not changing the vacuum tube apparent size, increases the strip ripple, thereby effectively increases intensity, vacuum and the heat-collecting capacity of thermal-collecting tube, reduces heat loss.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model section of structure.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment 2, and in Fig. 1, Fig. 2, the utility model is fixed with support member 6 between the nexine 5 of cover glass tube 1 and the skin 3 of inner glass tube 2 in vacuum interlayer 4, are used for fixed support inner glass tube 2.Skin at cover glass tube 1 is divided into 8 equal portions, and each equal portions is the longitudinal strip convex surface, and the nexine of inner glass tube 2 is divided into corresponding 8 equal portions, and each equal portions is the longitudinal strip convex surface.
Embodiment 3, and in Fig. 1, Fig. 2, the utility model is fixed with support member 6 between the nexine 5 of cover glass tube 1 and the skin 3 of inner glass tube 2 in vacuum interlayer 4, are used for fixed support inner glass tube 2.Be divided into 100 equal portions at cover glass tube nexine 5, each equal portions is the longitudinal strip convex surface, and the nexine of inner glass tube 2 is divided into corresponding 100 equal portions, and each equal portions is the longitudinal strip convex surface.
Claims (2)
