Description
Technical field
The utility model relates to the solar water heater parts, especially solar water heater cumulative vacuum tube.
Background technology
Traditional vacuum tube for solar water heater, its structure is made up of outer glass pipe, vacuum layer, the inner glass tube of column type, and interior glass outer surface is with heat absorbing coating.In order to increase the thermal-arrest ability of heat collecting vacuum pipe, Chinese patent CN200420107759 discloses a kind of " heat collecting vacuum pipe has the solar water heater in optically focused reflecting layer ", it plates the coat of metal on the inner surface of outer glass pipe bottom, in addition, Chinese patent ZL200820215438.1 disclosed " vacuum tube for solar water heater ", inner glass tube is designed rhombus or ellipse or rectangle or polygon, and the inwall at outer glass pipe has added reflector simultaneously.Their deficiency is that all the angle of the installation of solar energy is difficult to be consistent with the focal line of design; long deviation is arranged,, play the effect of gathering or focusing on though can adjust horizontal sunlight; but the offset issue of having ignored vertical sunlight, so Heat-collecting effect is not good.
Summary of the invention
The utility model just for overcoming above-mentioned deficiency, provide a kind of daylighting area many, reflective focal line is managed in thermal-arrest, keep the long-time good solar energy vacuum tube of Heat-collecting effect that highly overlaps, the main improvement is that the inwall reflector surface of outer glass pipe is equipped with the spill embossed pattern, concave is a camber line in this pattern, best results.Specifically implement like this: solar water heater cumulative vacuum tube, the outer glass pipe, vacuum layer, the inner glass tube that comprise column type, interior glass outer surface is with heat absorbing coating, the inwall of the outer glass pipe of column type is provided with reflector, it is characterized in that the reflector surface is equipped with the concave shaped embossed pattern.The utility model is arranged on the embossing on column type outer glass pipe inwall reflector surface, can limit the reflection angle of vertical sunlight effectively, in light is controlled in the active set heat rating of pipe, not allow its loss, utilized sunlight more, improve quantity of heat production, the focal line that it has corrected reflector is consistent itself and thermal-arrest inner glass tube, have overlapping for a long time, do not allow it that deviation is arranged, utilized the sunshine on the caustic so expeditiously, can accomplish heat production rapidly for a long time.
The interior concave of the utility model concave shaped embossed pattern is designed to camber line, best results, the size of radian is decided with the distance of inner and outer pipes, such concave shaped embossed designs, similarly be a plurality of solar cookers that dwindle, not only adjusted sunlight longitudinally effectively, and sunlight is focused on, make guarantee in focal line and the thermal-arrest hold overlapping for a long time, heat production more efficiently.
The concave shaped embossed pattern that the utility model is arranged on the outer glass pipe inwall reflector of high column type is highdensity concave shaped embossed pattern, and concave is a camber line in the pattern, rectifying effect the best.
By on the outer glass pipe inwall reflector of column type, the concave shaped embossed pattern being set, corrected the focal line of reflector, itself and thermal-arrest inner glass tube are consistent, can keep the overlapping for a long time deviation that do not have, Heat-collecting effect is good.
