Abstract

The utility model relates to a full glass heat-pipe solar vacuum heat collecting pipe, belonging to a solar energy heat collecting pipe. One end of an inner glass pipe is in the shape of a circular top, and one end of a cover glass pipe is a closed end. A support member is arranged between the inner glass pipe and the cover glass pipe. The other end of the inner glass pipe and the other end of the cover glass pipe are dissolved and sealed to become an annular opening end. The cover glass pipe is extended on the opening end, and the end point which is extended is provided with a closing head. The interior of the inner glass pipe is filled with a heat conducting medium. A film plating layer is arranged on the inner glass pipe. Vacuum is between two glass pipes. The structure of a water heater is simple. Water is heated by the heat conducting medium. The inner glass pipe can not be directly contacted with water, scale deposit can not be accumulated on the inner glass pipe, the heating efficiency of the full glass heat-pipe solar vacuum heat collecting pipe is enhanced, and the condition that the crack of the inner glass pipe generates due to the scale deposit is avoided.

Description

The all-glass heat pipe vacuum solar collector pipe
The utility model relates to a kind of solar energy heat collection pipe, particularly a kind of heat-tube vacuum solar collector pipe.
At present, domestic all glass vacuum heat collection tube of solar energy, constitute by inner glass tube with coating for selective absorption and coaxial cover glass tube, inner glass tube one end is the domed shape of sealing, cover glass tube one end is a blind end, cover glass tube is enclosed within outside the inner glass tube, between inner glass tube domed shape and cover glass tube blind end, a supporting member is arranged, with interior glass/glass supporting, getter is arranged on the supporting member, the molten envelope of other end inner glass tube and cover glass tube becomes the openend of ring-type, and a plated film layer is arranged on inner glass tube, will be evacuated between the layer glass pipe, water can flow in the inner glass tube, heated water is through convection current in inner glass tube, circulation reaches the purpose that adds hot water, when using solar water heater for a long time, in the inwall of glass tube, produce incrustation scale, the thermal efficiency reduces, and is too thick as incrustation scale, also the situation that glass tube bursts may occur.
The purpose of this utility model is that a kind of incrustation scale, all-glass heat pipe vacuum solar collector pipe that the thermal efficiency is high of can not producing in inwall will be provided.
The purpose of this utility model is achieved in that the openend at thermal-collecting tube prolongs cover glass tube, the end points that prolongs has a closed head, the cover glass tube that prolongs seals inner glass tube, simultaneously inner glass tube is evacuated, and charges into heat-conducting medium in inner glass tube.
Owing to adopted such scheme, direct contact water not in the inner glass tube is not so just produce incrustation scale on the wall of inner glass tube; Owing to charged into heat-conducting medium in the inner glass tube, inner glass tube directly with the water heating, makes the big raising of the thermal efficiency with the heat in the heat-conducting medium, has reached the purpose of this utility model.This water heater is simple in structure, directly water is heated by heat-conducting medium, and inner glass tube is direct contact water not, and non-scaling on the inner glass tube has improved the thermal efficiency of heating, avoided because glass inner tube produces incrustation scale, and the situation of the interior pipe explosion that takes place takes place.
Be described further in conjunction with the embodiments with reference to the accompanying drawings below.
Accompanying drawing is a structure chart of the present utility model.
Embodiment: solar energy heat collection pipe, constitute by inner glass tube 1 with coating for selective absorption 2 and coaxial cover glass tube 4, inner glass tube 1 one ends are the domed shape of sealing, cover glass tube 4 one ends are blind end, at the blind end internal layer getter minute surface 7 that evapotranspires is arranged, cover glass tube 4 is enclosed within outside the inner glass tube 1, between inner glass tube 1 domed shape and cover glass tube 4 blind ends, a supporting member 5 is arranged, with interior glass/glass 1 supporting, getter 6 is arranged on the supporting member 5, and other end inner glass tube 1 and cover glass tube 4 molten envelopes become the openend of ring-type, at openend cover glass tube 4 are prolonged, the end points that prolongs has a closed head, the cover glass tube 4 that prolongs is evacuated inner glass tube 1 sealing simultaneously with inner glass tube 1, charge into heat-conducting medium 9 in inner glass tube 1, one plated film layer is arranged on inner glass tube 1, will be evacuated 3 between the layer glass pipe.

Claims (1)

1, a kind of all-glass heat pipe vacuum solar collector pipe, comprise inner glass tube, cover glass tube, supporting member, it is characterized in that: the openend at thermal-collecting tube prolongs cover glass tube, the end points that prolongs has a closed head, the cover glass tube that prolongs seals inner glass tube, simultaneously inner glass tube is evacuated, in inner glass tube, charges into heat-conducting medium.
