Abstract
The utility model relates to a full glass vacuum solar heat collecting pipe with a contracted opening. The diameter of a pipe body on the opening end of the full glass vacuum solar heat collecting pipe with a contracted opening is reduced to form the shape of a contracted opening. The full glass vacuum solar heat collecting pipe with a contracted opening is used for assembling a solar energy water heater, the full glass vacuum solar heat collecting pipes with contracted openings can be close arranged, and the integral heat collecting efficiency can be enhanced.
Description
The utility model relates to a kind of vacuum solar collector tubes.
Up to now, the employed vacuum heat collection pipe of solar water heater is all near column type, and pipe diameter equates.Because water heater water butt bucket wall will have certain mechanical strength; Owing between the thermal-collecting tube of circular hole on the bucket wall and insertion thicker sealing ring is arranged, therefore, the water heater thermal-collecting tube that is assembled into can not closely be arranged again, and bigger at interval, solar energy utilization ratio is not high.Some water heater is lined with reflector at the thermal-collecting tube back side, but because the restriction of the reflecting rate of reflector material own adds that long-term use back dust and other materials pollute, reflecting effect is relatively poor.
The purpose of this utility model is improved vacuum heat collection pipe, and a kind of reducing complete glass vacuum sun thermal-collecting tube that can increase solar water heater integrated collecting efficiency is provided.
For achieving the above object, in the process of making vacuum heat collection pipe, with the reduced of one section body of vacuum heat collection pipe openend.Fig. 1 is a profile of the present utility model.Thermal-collecting tube is made up of glass round tube in the reducing (1) and the outer glass round tube (4) of reducing, interlayer (3) is evacuated between inner and outer pipe, the outer surface of pipe constituted absorber in solar energy selective sorbent surface (2) was deposited on, and solar energy is converted to heat energy, the heat-transfer fluid in the heating inner glass tube.This thermal-collecting tube adopts single-ended opening design, and the annular sealing by fusing of the inner and outer pipe of reducing one end is got up, and pipe other end is airtight hemispherical round end in it, has the spring clip (5) of getter (6), the inner glass tube round end is bearing in the exhaust inner end of outer glass pipe.Breathing film (7) is deposited on the exhaust inner end of outer glass pipe.
Because thermal-collecting tube inserts the reduced of water butt part, sealing ring no longer causes the interval between the thermal-collecting tube, and thermal-collecting tube can closely be arranged, and solar water heater has increased effective collector area, has improved whole collecting efficiency.Corresponding the reducing of thermal-collecting tube patchhole diameter on the water butt increased the intensity of water butt.
Below in conjunction with Fig. 2 an embodiment of the present utility model is described.
Fig. 2 has made broken section for selecting solar water heater front view of the present utility model for use to water butt, sealing ring and vacuum heat-collecting tube portion.Form the water heater water butt jointly by inner bag (1), insulation material (2), shell (3), sealing ring (4) is embedded on the circular hole of inner bag (1) reservation, after the reducing position of vacuum heat collection pipe (6) puts case ring (5), insert in the sealing ring (4) on the water butt, thermal-collecting tube closed end and water butt all are fixed on the support (7), and (8) are the inlet tube and outlet tube of water heater.
As can be seen from Figure 2, use solar water heater of the present utility model, thermal-collecting tube can closely be arranged, under the identical situation of water heater overall dimensions, more thermal-collecting tube can be installed, increased effective collector area, improved whole collecting efficiency, and saved the reflector at the thermal-collecting tube back side, simplified the structure, reduced cost.
