Abstract
An all-glass vacuum solar collector tube relates to solar heat utilization technical field, in particular to heat collector tube structure technical field of solar water heater. The all-glass vacuum solar collector tube comprises an outer glass tube and an inner glass tube; one end of the outer glass tube is connected with one end of the inner glass tube mutually, a vacuum cavity is formed between the inner and outer glass tubes, a selective heat-absorbing coating is arranged on the external surface of the inner glass tube, a segment of inner glass tube is cylindrical and the other segment is shaped like a flat cylinder, one end of the cylindrical segment is connected with the outer glass tube. As the large surface of the solar collector tube faces to sun, the sunshine irradiation area is not reduced basically, as a segment of inner glass tube is shaped like a flat cylinder, the inner capacity of the inner glass tube is effectively reduced compared with cylindrical structure in prior art, the interior medium storage in use is effectively reduced so that the heat exchange efficiency is improved, namely the heat utilization rate is improved.
Description
Technical field
The utility model relates to the thermal-collecting tube technical field of structures of solar energy heat utilization technical field, particularly solar water heater.
Background technology
The thermal-collecting tube of the existing solar water heater that generally adopts is the vacuum type double-layer glass tube mostly, sunlight is radiated at the outer surface of inner layer glass tube by outer layer glass tube, because the outer surface of inner layer glass tube scribbles the selective heat-absorbing layer, under its effect, transform light energy becomes heat energy, the heat conduction of the interior media (being generally water) by inner layer glass tube makes that water heats up in the water tank, and people use hot water.In order to accept sunlight to greatest extent, the caliber of present inner layer glass tube is bigger, causes the temperature rise speed of inner layer glass tube slower, and is little with water temperature difference in the water tank, can not in time that inner layer glass tube is higher warm water and water tank carry out convection current.And if directly dwindle the caliber of inner layer glass tube, then its area of accepting light irradiation directly is affected, and still can not obtain desirable effect.
The utility model content
The utility model purpose is to design a kind ofly can maximum area accept illumination, again can be by reducing all glass vacuum heat collection tube of solar energy of inner layer glass tube medium amount.
The utility model comprises outer glass pipe and inner glass tube, one end of described outer glass pipe and an end of inner glass tube interconnect, between inside and outside glass tube, vacuum chamber is set, the outer surface of inner glass tube is provided with selective heat absorbing coating, one section of described inner glass tube is cylindrical, another section is oblate cylindricality, and a described columniform end is connected with outer glass pipe.
During installation, the oblate cylindrical portion of inner glass tube of the present utility model faced sun greatly.Because the difference in interior outer glass pipe footpath, inner glass tube of the present utility model links to each other with outer glass pipe by cylindrical segment, and oblate cylindrical portion is the active set hot arc of inner glass tube.Owing to face sun greatly, do not reduce the terrestrial solar radiation area substantially, owing to make oblate cylindricality, more originally cylindrical, its internal volume is effectively reduced, and effective minimizing that can practical interior media storage can improve heat exchanger effectiveness, promptly improves heat utilization efficiency.
The inner surface setting projection entad of the oblate cylindrical portion of inner glass tube described in the utility model, described projection is extended on the length direction of inner glass tube.Because projection has increased the contact area of inner glass tube and Qi Nei medium, can improve the rate of heat exchange of inner glass tube and its interior medium, and increase intensity.
In addition, the outer surface of the oblate cylindrical portion of inner glass tube described in the utility model also can be provided with projection, and described projection is extended on the length direction of inner glass tube.
Describedly oblately can be ellipse, also can be for oval.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the left side view of Fig. 1.
Fig. 3 is that a kind of A-A of Fig. 1 is to sectional drawing.
Fig. 4 is that the another kind of A-A of Fig. 1 is to sectional drawing.
The specific embodiment
As shown in Figure 1, 2, the utility model is provided with circular outer glass pipe 1 and inner glass tube 2,2 one sections cylindrical 2-1 of inner glass tube, and another section is oblate cylindricality 2-2, and an end of its cylindrical 2-1 section and an end of outer glass pipe 1 seal welding mutually.Vacuum chamber 3 is set between inside and outside glass tube, and the outer surface of inner glass tube 2 is provided with selective heat absorbing coating.
As shown in Figure 3, the cross section that is oblate cylindricality 2-2 section of inner glass tube 2 also can be oval (also claiming runway shape) for oval.
As shown in Figure 4, the inner surface of the oblate cylindricality 2-2 section of inner glass tube 2 is provided with some protruding 2-3 entad, and each protruding 2-3 extends to form raised line on the length direction of inner glass tube 2.In addition, the outer surface of oblate cylindricality 2-2 section also is provided with some protruding 2-4, and each protruding 2-4 extends to form raised line on the length direction of inner glass tube 2.
