Abstract
The utility model provides an improved all-glass internal condensation vacuum solar collector which consists of a double-layer glass vacuum inner tube, an outer tube and an elastic bracket support arranged between the inner tube and the outer tube; the improved all-glass internal condensation vacuum solar collector is characterized in that the shape of the outer tube is designed to be of a shape like a pulled Chinese character 'Zhong' which is thin in the two ends and thick in the middle; the inner tube is of a cylinder shape and is sleeved with the two ends of the outer tube; and a reflector is coaxially arranged between the inner tube and the outer tube. The technical scheme adopted by the improved all-glass internal condensation vacuum solar collector is as follows: as the outer tube adopts an externally expanded shape like a Chinese character 'Zhong', the heat absorption area is enlarged; meanwhile, a space is created for arranging the reflector between the inner tube and the outer tube; partial sunshine entering the area of the outer tube is directly absorbed by the inner tube and another part of sunshine is reflected into the inner tube and the outer tube and absorbed by a vacuum cavity through the paraboloid of the reflector at the lower surface of the inner tube; therefore, the solar collection efficiency of the vacuum solar collector is greatly improved.
Description
Technical field
The utility model relates to light collecting vacuum heat collection pipe in a kind of improved full glass, belongs to the solar energy heat collection pipe technical field.
Background technology
What have the used vacuum tube of vacuum pipe solar water heater now all is the cylindrical glass tube of intussusception, and the upper end sealing is coated with absorption film on the inner tubal wall, and the shortcoming of this structure is that the insulation after the interior pipe heat absorption only relies on by means of vacuum heat-insulating layer, and insulating efficiency haves much room for improvement.
Summary of the invention
The purpose of this utility model is to provide light collecting vacuum heat collection pipe in a kind of improved full glass, enlarges outer vacuum tube and increases the heat absorption daylighting area, sets up reflector simultaneously to improve insulating efficiency.
The technical solution of the utility model is achieved in that light collecting vacuum heat collection pipe in this improved full glass, by managing in the double-glass vacuum, the elastic support that is provided with between outer tube and the inner and outer pipe supports and constitutes, it is characterized in that: the outer tube shaped design be elongation thick between the detail of two ends " in " font, interior pipe is for cylindrical, with the socket of outer tube two ends.
Light collecting vacuum heat collection pipe in the described improved full glass axially is provided with reflector between inner and outer pipe.
The below of pipe sunny slope in light collecting vacuum heat collection pipe in the described improved full glass, one or two parabola of described reflector are arranged at.
Light collecting vacuum heat collection pipe in the described improved full glass, the inwall of interior pipe or outer wall have light-absorbing coating in order to absorb sunlight.
Light collecting vacuum heat collection pipe in the described improved full glass, described elastic support are arranged at the fixing interior pipe of an end of thermal-collecting tube.
The technical solution adopted in the utility model, because adopting, outer tube extends out middle word shape, enlarged endotherm area, opened up the space between the inner and outer pipes reflector being set simultaneously, a sunlight part that enters the outer tube zone is directly absorbed by interior pipe, the reflector parabolic reflector of another part below interior pipe to inner and outer pipes vacuum chamber absorbs, thereby can improve the collecting efficiency of vacuum heat collection pipe greatly.
Description of drawings
Fig. 1 is the generalized section of the utility model thermal-collecting tube
Fig. 2 is the A-A view of Fig. 1
Among the figure: 1, outer tube 2, interior pipe 3, reflector 4, elastic support
The specific embodiment
Fig. 1 is the structural representation of light collecting vacuum heat collection pipe in the improved full glass of the utility model, innovative point be the outer tube 1 at double-deck solar energy vacuum tube be designed to elongation thick between the detail of two ends " in " font, interior pipe 2 is cylindrical, form with outer tube 1 rounding off sintering, be convenient to install and fix the two ends socket.Reflector 3 axially is set between inner and outer pipe.
There is light-absorbing coating the below of pipe sunny slope in one or two parabola of reflector 3 is arranged at, the inwall of interior pipe 2 or outer wall in order to absorb sunlight, and elastic support 4 is arranged at the fixing interior pipe of an end of thermal-collecting tube, as shown in Figure 2.
Foregoing description only proposes as the enforceable technical scheme of light collecting vacuum tube thermal-collecting tube in the improved full glass of the utility model, not as the single restrictive condition to its structure itself.
