Abstract
The utility model relates to a solar vacuum tube with a reflector, for improving the heating efficiency, the position relation between a vacuum tube and a reflecting plate is solved, The solar vacuum tube is the solar vacuum tube with the reflector, which comprises an inner glass tube and a cover glass tube, wherein an absorbing layer is arranged on the external surface of the inner glass pipe. A mirror surface coating is arranged on the external surface of the lower half portion of a cover glass shaft, mirror surface coating materials are aluminum or silver, and the axial length of the mirror surface coating is more than a half of the length of the cover glass tube. The mirror surface coating with high reflectance is sprayed or is plated on the external wall of the lower half portion of the cover glass tube of the vacuum tube, which forms a sunlight focusing mirror, the principle of concentrating light and collecting heat through reflection is utilized, firstly, heat of sunlight is reflected into a heat absorbing pipe in the inner for improving the heat collecting efficiency, secondly, the radiating heat from the inner glass pipe is reflected backwards for increasing the temperature protection effect. The tube can not reduce the reflecting efficiency due to pollution, can not increase the wind resistance due to the reflecting plate, the manufacturing cost is low and the manufacturing technique is good.
Description
Technical field
The utility model relates to a kind of solar energy vacuum tube.
Background technology
The vacuum tube of existing solar vacuum-tube water heater and the relation of reflector mainly contain three kinds of situations: 1, reflector is installed in the vacuum tube below, this reflector is most of to be made with aluminium skin or stainless sheet steel, be installed on the support of carrying vacuum tube and water tank, be under the vacuum tube.The major defect of this assembling is: contaminated easily, lose reflecting effect; Windage is big, and solar water heater is easily blown to turn over; Cost is higher; The difficult reflector of installing of engineering module.2, reflector is installed on the interlayer of inner and outer pipes, and the vacuum tube reflective surface of this band reflector is less, and complicated difficult popularization of manufacture craft.3, reflecting material on the latter half of the inwall of vestlet sprays outside vacuum tube is made speculum and is come reflected sunlight.This also fails to promote because of factors such as technology always and opens.
Summary of the invention
In order to solve the position relation of vacuum tube and reflector, improve the thermal efficiency, the utility model provides a kind of new construction to have the solar energy vacuum tube of reflective mirror.
Solar energy vacuum tube with reflective mirror comprises inner glass tube and cover glass tube, and the outer surface of inner glass tube is established absorber coatings,
The outer surface of the axial the latter half of described cover glass tube is provided with reflecting layer.
Described reflecting layer material is aluminium or silver.
The axial length of described reflecting layer is the over half of cover glass tube length.
The utility model sprays or plates the reflecting layer of one deck high reflectance on the outer wall of the latter half of vacuum tube cover glass tube, form the sunlight focus lamp, utilize reflecting condensation thermal-arrest principle, A, the reflect heat of sunshine is improved collecting efficiency to inner endothermic tube; B, will reflect back, increase heat insulation effect from the radiations heat energy of inner glass tube.The utility model can not reduce reflecting rate because of polluting; Can not cause windage to strengthen because of reflector; Its production cost is low, and anufacturability is good.
