Abstract
The utility model discloses a kind of solar vacuum heat-collecting pipe, comprising outer tube and interior pipe, is vacuum heat-insulating layer between outer tube and interior pipe, and described outer tube outer surface scribbles anti-film, rupture pressure disc skin is provided with antireflective coating, described interior pipe is corrugated or zigzag structure, and described inner tube outer surface scribbles one deck absorption film, described interior pipe one end conducting, the other end is closed, one end of conducting is provided with separator tube, and described separator tube one end and outer tube are fixed, and the other end and interior pipe are fixed.Solar vacuum heat-collecting pipe of the present utility model effectively can increase outer wall of inner tube area and increase endothermic effect when thermal-collecting tube inner tube length is constant, improve the conversion ratio of solar energy, and can avoid occurring blasted pipe phenomenon, reasonable in design, safe and reliable.
Description
Technical field
The utility model relates to technical field of solar water heaters, specifically belongs to a kind of solar vacuum heat-collecting pipe.
Background technology
Solar water heater, with its environmental protection, low-carbon (LC), sanitation and hygiene, the feature such as safe and reliable, is more and more subject to consumers.Solar water heater produces hot water and mainly relies on vacuum heat collection pipe, and vacuum heat collection pipe is the heat collecting element in solar energy heating hydrophone, and vacuum heat collection pipe gathers solar energy, is heated up by the water in water tank.
Current vacuum heat collection pipe is all pipe in long straight drum-shaped, this interior pipe be received in accept sunlight time, the conversion ratio of solar energy is very low, and collecting efficiency is not generally higher than 50%.In addition, there is crackly problem in existing solar vacuum heat-collecting pipe, in the winter time the freezing situation of vacuum heat collection pipe often can occur, ambient temperature decline after, the water in vacuum tube can condense, freeze, by vacuum tube bursting by freezing after volumetric expansion.And the expansion rate of inner and outer tubes is inconsistent, when being heated, both contact positions produce irregular stress, easily cause outer glass tube to break, often easily form bombing.
Utility model content
The purpose of this utility model there is provided a kind of solar vacuum heat-collecting pipe, effectively can increase outer wall of inner tube area when thermal-collecting tube inner tube length is constant and increase endothermic effect, improve the conversion ratio of solar energy, and can avoid occurring blasted pipe phenomenon, reasonable in design, safe and reliable.
The technical solution adopted in the utility model is as follows:
A kind of solar vacuum heat-collecting pipe, comprising outer tube and interior pipe, is vacuum heat-insulating layer between outer tube and interior pipe, and described outer tube outer surface scribbles anti-film, rupture pressure disc skin is provided with antireflective coating, described interior pipe is corrugated or zigzag structure, and described inner tube outer surface scribbles one deck absorption film, described interior pipe one end conducting, the other end is closed, one end of conducting is provided with separator tube, and described separator tube one end and outer tube are fixed, and the other end and interior pipe are fixed.
Described interior pipe is corrugated is transverse wave structure, and cross section is circular.
Described interior pipe zigzag is horizontal sawtooth structure, and cross section is circular.
Described separator tube has three.
Described separator tube is made up of stainless steel material
Compared with the prior art, the beneficial effects of the utility model are as follows:
Solar vacuum heat-collecting pipe of the present utility model, interior pipe adopts transverse wave structure, and interior pipe unit length was managed in the past, but tube wall area increases, cross section is circular not by the impact of lighting angle, and endothermic effect is better, ripple struction processing and fabricating is convenient, is convenient to produce; And scribbling anti-film at the outer surface of outer tube, rupture pressure disc skin is provided with antireflective coating, and inner tube outer surface scribbles one deck absorption film, can improve the solar collecting performance of thermal-collecting tube further, improves the conversion ratio of solar energy; Meanwhile, tube outer surface scribbles anti-film outside, is provided with separator tube between interior pipe and outer tube, and like this when inner and outer tubes expanded by heating, avoid outer tube bombing, usage safety performance is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
See accompanying drawing, a kind of solar vacuum heat-collecting pipe, comprise outer tube 1 and interior pipe 2, it is vacuum heat-insulating layer 3 between outer tube and interior pipe, described outer tube 1 outer surface scribbles anti-film, rupture pressure disc skin is provided with antireflective coating, described interior pipe 2 is corrugated or zigzag structure, cross section is circular, described interior pipe 2 outer surface scribbles one deck absorption film, described interior pipe 2 one end conducting, the other end is closed, one end of conducting is provided with three separator tubes 4, described separator tube 4 one end and outer tube 1 are fixed, the other end and interior pipe 2 are fixed, described separator tube 4 is made up of stainless steel material.Interior pipe 2 of the present utility model adopts transverse wave structure, and interior pipe 2 unit length was managed in the past, but tube wall area increases, and cross section is circular, and not by the impact of lighting angle, endothermic effect is better, and ripple struction processing and fabricating conveniently, is convenient to produce; And scribbling anti-film at the outer surface of outer tube 1, rupture pressure disc skin is provided with antireflective coating, and interior pipe 2 outer surface scribbles one deck absorption film, can improve the solar collecting performance of thermal-collecting tube further, improves the conversion ratio of solar energy; Meanwhile, scribble anti-film at outer tube 1 outer surface, be provided with separator tube 4 between interior pipe 2 and outer tube 1, like this when interior pipe 2 and outer tube 1 expanded by heating, avoid outer tube bombing, usage safety performance is good.
