Abstract
The invention discloses a vacuum collector tube, which comprises an elliptical inner glass tube and a circular cover glass tube. The circular bottom of the elliptical inner glass tube is enclosed; the surface of the elliptical inner glass tube is plated with a solar selective absorption coating; the opening end of the elliptical inner glass tube is connected with the opening end of the circular cover glass tube in a sealing way; the circular bottom of the elliptical inner glass tube is provided with a spring support frame which is fixed with the inner wall of the cover glass tube in a tensioning way; a vacuum sandwich is formed between the elliptical inner glass tube and the circular cover glass tube, and the vacuum degree of the sandwich is maintained by a getter. The vacuum collector tube has the advantages of quick temperature rise, high heat exchange efficiency, low consumption of glass materials.
Description
Technical field
The present invention relates to a kind of vacuum heat collection pipe that is used for the true water heater of the sun.
Background technology
The regular solar vacuum heat collection pipe is all with inside and outside concentric structure; Through interior outer glass pipe sealing-in; The mode that interlayer vacuumizes is made, because the disc structure has maximum cubical content, so has bigger water capacity in the vacuum tube; Thereby cause the vacuum tube can't fast lifting thermal siphon pressure head, cause the not high shortcoming of heat exchange efficiency.
Summary of the invention
The shortcoming that the present invention will solve in the existing vacuum heat collection pipe can't fast lifting thermal siphon pressure head, heat exchange efficiency is not high provides a kind of fast lifting thermal siphon pressure head, vacuum heat collection pipe that heat exchange efficiency is not high.
Vacuum heat collection pipe; It is characterized in that: comprise oval inner glass tube and circular enclosure glass tube; Said oval inner glass tube round bottom sealed knot; Said oval inner glass tube surface is coated with solar selective absorbing coating, said oval inner glass tube openend and the sealing-in of cover glass tube openend, and said oval inner glass tube round bottom place is provided with spring bracing and the tensioning of cover glass tube inwall is fixed; Between said oval inner glass tube and the cover glass tube is a vacuum interlayer, and has getter to keep layer vacuum.
Further, described oval inner glass tube with the minor axis of cross section towards sunlight.
Further, said spring bracing comprises a plurality of spring card bases, and said annulus is provided with getter, and support frame as described above is placed in oval inner glass tube round bottom through the oval inner glass tube of card base support fixation, and said cover glass tube round bottom center position is provided with steam vent.
Pipe is compared with circular interior pipe in oval, under equal sensitive surface condition, and water capacity in the interior pipe, fast lifting siphon heat transfer rate reaches the effect that is rapidly heated, and the siphon heat exchange is more obvious, will significantly improve heat absorption efficiency.
Simultaneously, pipe is compared with interior pipe of circle in the ellipse, has materials and reduces and the constant characteristics of daylighting face, manages originally needed heat in temperature-rise period in helping reducing.The vacuum interlayer volume of inner and outer pipes interlayer also increases simultaneously, and vacuum tube has discharge quantity still less under the condition of high temperature, and therefore the maintenance to the vacuum in the vacuum tube interlayer also has good effect.
Advantage of the present invention: temperature rise is fast, the raising heat exchanger effectiveness, can reduce the consumption of glass material simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a cross-sectional view of the present invention.
The specific embodiment:
With reference to accompanying drawing:
Vacuum heat collection pipe of the present invention; Comprise oval inner glass tube 1 and circular enclosure glass tube 4; Said oval inner glass tube 1 round bottom sealed knot; Said oval inner glass tube 1 surface is coated with solar selective absorbing coating 2, said oval inner glass tube 1 openend and cover glass tube 4 openend sealing-ins, and said oval inner glass tube 1 round bottom place is provided with spring bracing 5 and fixes with cover glass tube 4 inwall tensionings; Be a vacuum interlayer 3 between said oval inner glass tube 1 and the cover glass tube 4, and have getter 6 to keep vacuum interlayer 3 vacuums.
Described oval inner glass tube 1 with the minor axis of cross section towards sunlight.Generally according to the strongest direction of noon sun be provided with described minor axis towards.In the time of in the morning with dusk sunlight oblique fire, oval inner glass tube will be with the inclination mode of deflection major axis towards sunlight, and light-receiving area diminishes.But, consider and using on the plane skylight of circular inner glass tube, after the penetrating of sunlight oblique fire, shading each other between the glass tube, the light-receiving area of long axis direction of the present invention reduces, and does not constitute technical inferior position.
Said spring bracing 5 comprises a plurality of spring card bases; The annulus of spring bracing 5 is provided with getter; Support frame as described above is placed in oval inner glass tube 1 round bottom through the oval inner glass tube 1 of card base support fixation, and said cover glass tube 4 round bottom center positions are provided with steam vent.
Pipe is compared with circular interior pipe in oval, under equal sensitive surface condition, and water capacity in the interior pipe, fast lifting siphon heat transfer rate reaches the effect that is rapidly heated, and the siphon heat exchange is more obvious, will significantly improve heat absorption efficiency.Experiment shows that under equal conditions, the present invention is higher by 30% than the vacuum heat collection pipe temperature rise speed that adopts circular interior pipe, and the siphon heat exchange phenomenon is powerful, and the siphon heat exchange effect is better.
The described content of this specification embodiment only is enumerating the way of realization of inventive concept; Should not being regarded as of protection scope of the present invention only limits to the concrete form that embodiment states, protection scope of the present invention also reach in those skilled in the art conceive according to the present invention the equivalent technologies means that can expect.
