Abstract
The utility model discloses a solar energy vacuum heat collecting tube which comprises a glass outer tube and a metal inner tube. The end portion of the glass outer tube and the end portion of the inner tube are provided with a metal end cover. The outer surface of the metal end cover is covered by an annular heat insulation pad. The solar energy vacuum heat collecting tube has the advantages that the heat insulation pad is tightly attached to the metal end cover of vacuum heat collecting tube, the metal end cover is prevented from being directly contacted with air, heat transmission of the metal end cover and the external world is effectively isolated, heat losses are reduced, and heat collecting efficiency is improved.
Description
Technical field
The utility model relates to a kind of solar vacuum heat-collecting pipe.
Background technology
The vacuum heat collection pipe of using in the existing medium and high temperature solar groove type light and heat collection system is made of glass outer tube, metal inner pipe, metal end.Sunshine is on the interior pipe absorber of focus irradiation at every vacuum heat collection pipe, and the heat transfer medium flows in the absorber conducts heat to application end.Mid portion relies on the high vacuum between inner and outer pipes to be down to its heat loss minimum, but, the metal end at two ends is because be metal material, if do not do heat insulation processing, in the heat transfer process, the heat in the interior pipe reaches metal end through three kinds of thermaltransmission modes (hot conduction, thermal convection current, heat radiation), if metal end contacts with air, this part heat will scatter and disappear fast, thereby has increased the heat loss of described vacuum heat collection pipe.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of minimizing thermal loss, improves the solar vacuum heat-collecting pipe of collecting efficiency.
The utility model is realized by following measure:
A kind of solar vacuum heat-collecting pipe of the present utility model comprises glass outer tube and metal inner pipe, glass
Outer tube and metal inner pipe end are provided with metal end, and the outer surface of described metal end is coated with the heat insulating mattress of annular.
Above-mentioned heat insulating mattress is made by the aerosil felt insulation.
The thickness of above-mentioned heat insulating mattress is 3 ~ 6mm.
The beneficial effects of the utility model are: heat insulating mattress is close on the metal end of vacuum heat collection pipe, prevent that metal end from directly contacting with air, effectively completely cut off the heat transmission of crown cap with the external world, reduce the thermal loss of described vacuum heat collection pipe self, increased the collecting efficiency of vacuum heat collection pipe.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1 glass outer tube, 2 heat insulating mattress, 3 metal ends, 4 metal inner pipes.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.
Fig. 1 shows structural representation of the present utility model.Metal end 3 is as connecting the intermediate member of glass outer tube 1 with metal inner pipe 4.Annular heat insulating mattress 2 has covered the exposed aerial parts of metal end 3 fully, make metal end 3 can not be directly and air carry out heat exchange.Heat insulating mattress is made by the aerosil felt insulation.Through overtesting, when the thickness of heat insulating mattress 2 is 3 ~ 6mm, best results.
Contain aeroge and silicon in the aerosil felt insulation, aeroge is good heat insulator, and it almost can block the transfer of heat of being brought by three kinds of heat transfer types (hot conduction, thermal convection current, heat radiation).The component ratio of air accounts for more than 99.8% at least in the aeroge, and air is the non-conductor of heat, so they are good heat conduction barrier materials.Because silicon also is the non-conductor of heat, so the thermal conductivity factor of silicon gel only is: 0.013 ~ 0.025W/(mk).With regard to the mode of thermal convection current, because air can't be crossed over gel surface row convection action, it also is good thermal convection current barrier material.Therefore the utility model selects for use the aerosil felt insulation as the raw material of heat insulating mattress.
Heat insulating mattress 2 prevents that metal end 3 from directly contacting with air and carry out heat exchange, reduces the thermal loss of described vacuum heat collection pipe self, has increased the collecting efficiency of described vacuum heat collection pipe.
The preferred embodiment of this patent should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the art of this patent principle, can also make some improvement and replacement, and these improvement and replacement also should be considered as the protection domain of this patent.
