Description
Technical field
The present invention relates to a kind of all-glass heat pipe vacuum solar energy heat collection pipes, belong to solar energy utilization technique field.
Background technique
Conventional all-glass heat pipe vacuum solar collector pipe, structure is as shown in Figure 1, by with solar selective absorbing coating
3 inner glass tube 2 and coaxial cover glass tube 5 are constituted, and one end of inner glass tube 2 is overhanging and constitutes condensation segment 1, and the other end is located at
Evaporator section 4 is constituted inside cover glass tube 5, the evaporator section 4 is closed domed shape, and by 5 sealed-off end of cover glass tube
Supporting member 6 with getter 8 supports；Heat absorption working medium 7 is injected in inner glass tube 2.
The all-glass heat pipe vacuum solar collector pipe that market today is produced and used, generally existing getter mirror surface A are blocked
The problem of, prevent the round end of inner glass tube 2 from obtaining the irradiation of the sun, the heating of the heat absorption working medium 7 at round end is affected, and makes
Solar energy collection tube starting speed is obtained to be affected.
Aiming at the problem that getter mirror surface A is blocked, those skilled in the art attempt using the side for shortening inner glass tube round end
Formula solves, it has been found that and though inner glass tube round end shorten how much, getter mirror surface A height always follows inner glass tube round end to become
Change direction and change, and getter mirror surface A always blocks inner glass tube round end 2-3cm, there is no any effects.
Summary of the invention
Therefore, the present invention is directed to above situation, provides a kind of fast actuated type all-glass heat pipe vacuum solar energy heat collection pipe, solves
The slow problem of certainly above-mentioned starting.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of fast actuated type all-glass heat pipe vacuum solar energy heat collection pipe, including inner glass tube and cover glass tube, in interior glass
Heat absorption working medium is injected in glass pipe, one end of inner glass tube is overhanging and constitutes condensation segment, the other end be located inside cover glass tube and
Evaporator section is constituted, the evaporator section is supported by the supporting member in cover glass tube with getter；
It is characterized by: round end inner wall of the direction towards the cover glass tube that evapotranspire of the getter.
The fast actuated type all-glass heat pipe vacuum solar energy heat collection pipe, in which: the getter is capable of forming from institute
State the getter mirror surface with certain length that the evaporator section of round end inner wall toward the inner glass tube of cover glass tube extends, the interior glass
The bottom round end of glass pipe is located at except the getter mirror surface.
The fast actuated type all-glass heat pipe vacuum solar energy heat collection pipe, in which: in the circle apart from the cover glass tube
Circumferentially heat rolling forms a circle internal projecting ring on the pipe shaft of the position of head inner wall certain distance, and the supporting member passes through the convex
Ring and position, the certain distance be greater than or equal to the certain length.
The fast actuated type all-glass heat pipe vacuum solar energy heat collection pipe, in which: the getter is capable of forming from institute
The getter mirror surface with certain length that the evaporator section of round end inner wall toward the inner glass tube of cover glass tube extends is stated, it is described certain
Distance is greater than or equal to the certain length.
Compared with prior art, by adopting the above technical scheme present invention has the advantage that: by by the suction
Round end inner wall of the direction towards the cover glass tube that evapotranspire of gas agent, the air-breathing for fixing the getter forming position and length
Then agent mirror surface makes the end of the condensation segment of the inner glass tube be located at the position except the getter mirror surface, can avoid
The getter mirror surface blocks, and improves the starting speed of thermal-collecting tube.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of conventional all-glass heat pipe vacuum solar collector pipe；
Fig. 2 is the structural schematic diagram of fast actuated type all-glass heat pipe vacuum solar energy heat collection pipe provided by the invention.
Description of symbols: condensation segment 1；Inner glass tube 2；Solar selective absorbing coating 3；Evaporator section 4；Cover glass tube 5；
Supporting member 6；Heat absorption working medium 7；Getter 8；Internal projecting ring 9；Round end inner wall 10；Getter mirror surface A, B.
Specific embodiment
In view of the above technical problems, designer of the invention discovery, the key factor for influencing getter mirror position are to inhale
The direction of evapotranspiring of gas agent 8 need to only fix getter 8 when the direction of evapotranspiring of getter 8 is towards 5 round end inner wall of cover glass tube
Position, the getter mirror surface B location after evapotranspiring be it is fixed, the length for changing inner glass tube will not influence getter mirror surface
The height of B adjusts inner glass tube length at this time, can avoid getter mirror surface B.
As shown in Fig. 2, the present invention provides a kind of fast actuated type all-glass heat pipe vacuum solar energy heat collection pipe, with the prior art
It is identical, the cover glass tube 5 including inner glass tube 2 and coaxial welding with solar selective absorbing coating 3, inner glass tube 2
One end is overhanging and constitutes condensation segment 1, and the other end is located at 5 inside of cover glass tube and constitutes evaporator section 4, and the evaporator section 4 is closing
Domed shape, and supported by the supporting member 6 with getter 8 in 5 sealed-off end of cover glass tube；It is injected in inner glass tube 2
Heat absorption working medium 7；
And present invention is characterized in that round end inner wall of the direction towards the cover glass tube 5 that evapotranspire of the getter 8
10, so that will form from what the evaporator section 4 of round end inner wall 10 toward the inner glass tube 2 of the cover glass tube 5 extended has both fixed length
The end of the evaporator section 4 of the inner glass tube 2 is shortened at this time, is located at the getter mirror surface by the getter mirror surface B of degree
Position except B can avoid blocking for the getter mirror surface B.
For the ease of controlling the certain length of getter mirror surface B, the present invention is in the round end apart from the cover glass tube 5
Circumferentially heat rolling forms a circle convex on the pipe shaft of the position of 10 certain distance of inner wall (being greater than or equal to the certain length)
The cross-sectional shape of ring 9, the internal projecting ring 9 is advisable with semicircle, and the supporting member 6 (i.e. clamp) passes through the internal projecting ring 9
Positioning, it is thus possible to which the depth of the round end of control evaporator section 4 in inner glass tube 2 and 5 welding of cover glass tube makes evaporator section 4
Round end is located at except getter mirror surface B.
Described above to be merely exemplary for the purpose of the present invention, and not restrictive, those of ordinary skill in the art understand,
Without departing from the spirit and scope defined by the claims, can many modifications may be made, variation or equivalent, but will all fall
Enter within protection scope of the present invention.
