Abstract
The utility model discloses a reducing energy gathering all-glass vacuum heat collection tube, which comprises an outer tube and an inner tube, wherein a vacuum sandwich layer is arranged between the outer tube and the inner tube; the outer wall of the inner tube is coated with a selective absorption coating; the cross sections of the outer tube and the inner tube are eccentric circles; a highly reflective silver mirror is coated on the inner wall of the outer tube on one side close to the inner tube; and a nozzle section of the outer tube is reducing and is hermetically connected with the inner tube. Compared with the conventional products, the reducing energy gathering all-glass vacuum heat collection tube has the advantages of capabilities of increasing the heat collection area and fully utilizing solar heat energy, high heat efficiency, quick heating and starting, good thermal insulation and good social benefit and economic benefit.
Description
Technical field
The utility model relates to a kind of vacuum heat collection pipe of solar water heater, especially a kind of energy collecting type all-glass vacuum thermal-collecting tube of undergauge.
Background technology
Solar water heater is because its energy-conserving and environment-protective, aboundresources and be widely used in life, but the vacuum tube that general solar water heater uses, mainly be to absorb solar heat by the coating for selective absorption that is coated in outer wall of inner tube, endotherm area is less, and the utilization rate of solar energy is not high; On the other hand, because vacuum tube mouth of pipe section is identical with the pipe shaft diameter, it is larger to be installed on the incubator gap between each vacuum tube, need to take larger roof area.
The utility model content
Technical problem to be solved in the utility model is, overcomes the above defective, provide a kind of thermal efficiency high, start soon, heat radiation is few, the undergauge cumulative all-glass vacuum thermal-collecting tube that is used for solar water heater that temperature retention time is long.
In order to solve the above technical problem, a kind of undergauge cumulative of the utility model all-glass vacuum thermal-collecting tube, comprise outer tube and inner tube, it is vacuum interlayer between outer tube and the inner tube, outer wall in inner tube scribbles coating for selective absorption, the cross section of described outer tube and inner tube is off-centre operation, and outer tube scribbles high reflection silver mirror from the inwall of the nearly side of inner tube, and the mouth of pipe section of outer tube is undergauge shape and inner tube sealing-in.
Undergauge cumulative all-glass vacuum thermal-collecting tube described in the utility model, described outer tube scribbles high reflection silver mirror on the inwall of the nearly side of inner tube, sunlight shines high reflection silver mirror face, be reflected on the coating for selective absorption of inner tube, be heat energy with transform light energy, guaranteed enough collector areas, maximally utilised solar heat, the thermal efficiency is high; The outer tube mouth of pipe is the undergauge shape, is convenient to thermal-collecting tube solid matter on incubator, reduces the solar energy area occupied, also is convenient to install; Diameter of inner pipe freely is as the criterion with the current smoothness, outer tube only otherwise more thick better in the normal situation about using of impact, vacuum interlayer between the inner and outer pipes is large, heat insulation effect significantly improves, collector area is large, inner tube is filled with water, and few intensification is quite fast, even if winter, broken sky are as long as there is just energy output hot water of faint sunlight.
The beneficial effects of the utility model: the utility model is compared with existing product, increased the vacuum interlayer between collector area and the inner and outer pipes, heat absorption is many, high insulating effect, and inner tube is thin, heating starting is fast, the thermal efficiency is high, and the mouth of pipe is the undergauge shape, is convenient to thermal-collecting tube solid matter on incubator, reduce the solar energy area occupied, also be convenient to install.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
A kind of undergauge cumulative of the utility model all-glass vacuum thermal-collecting tube, comprise outer tube 1 and inner tube 2, be vacuum interlayer between outer tube 1 and the inner tube 2, outer wall in inner tube 2 scribbles coating for selective absorption 3, the cross section of described outer tube 1 and inner tube 2 is off-centre operation, outer tube 1 scribbles high reflection silver mirror 4 from the inwall of the nearly side of inner tube 2, and the mouth of pipe section of outer tube 1 is undergauge shape and inner tube sealing-in.
Embodiment: outer tube 1 described in the utility model and inner tube 2 are all made with satisfactory glass, and the diameter of described inner tube 2 is 2/3rds of outer tube 1 diameter.At first with the outer tube undergauge or connect tubule, then plate high reflection silver mirror 4 at outer tube 1 inwall half cycle, as condenser mirror, the inner tube 2 that to plate again coating for selective absorption 3 is assembled in the outer tube 1 from scribbling the side of high reflection silver mirror 4 close to, inner tube 2 is dropped on the optically focused focus of high reflection silver mirror 4, the mouth of pipe is done the round end sealing get final product.Inner tube center line described in the utility model deflection outer tube scribbles the half cycle of silver mirror, is eccentric shape, and the center line behind the center line of inner tube and the outer mouth of pipe undergauge is coaxial.
It below only is a kind of embodiment of the present utility model; the size of inner and outer tubes described in the utility model does not limit; the inner tube selection standard is freely to be as the criterion with the current smoothness; and the standard of outer tube is not affect normal use to be the bigger the better; as long as used the above structure, all should fall into protection domain of the present utility model.
