Abstract
The utility model discloses an all-glass solar heat pipe with silica sand against splashing, which comprises an outer glass pipe and an inner glass pipe with an absorbing coating coated on the outer wall, wherein the sandwich layer of the outer glass pipe and the inner glass pipe is vacuum; and the inner glass pipe is vacuumized and is provided with a heat-conducting medium therein. The all-glass solar heat pipe further comprises a condensation tube; the end parts of both the outer glass pipe and the inner glass pipe are in melt sealing to form an end surface which is in connection with the condensation tube in a melt sealing manner; and the condensation tube is communicated with the inner glass pipe with a small quantity of silica sand at the bottom thereof. The all-glass solar heat pipe has the advantages of simple structure, good heat collection effect and long service life.
Description
Technical field
The utility model relates to a kind of solar energy heat collection pipe, is specifically related to the anti-full-glass solar energy heat pipe that splashes of a kind of employing silica sand.
Background technology
At present, shortage along with non-renewable energy resources, more and more obtain people's attention such as this regenerative resource of solar energy, therefore solar water heater is widely used and popularize, and the vacuum heat collection pipe that is applied to solar water heater along with the raising of consumer demand also in constantly improvement.The full-glass solar energy heat pipe is that an inside and outside bimetallic tube and mono-layer tube form, and is the condition of high vacuum degree interlayer between inner and outer pipes, and interior tube cavity has rough vacuum.Inside and outside bimetallic tube one end is solar energy heat collection pipe, i.e. evaporator section, and mono-layer tube one end is condensation segment, i.e. heat exchange segment.The end of existing full-glass solar energy heat pipe outer tube section on inner pipe is melting sealed with its outer wall, and melting sealed sentencing down is that inside and outside bimetallic tube is evaporator section, and is condensation segment for mono-layer tube more than melting sealed place.This kind structure very easily causes the melting sealed place fracture of outer tube and inner tube, and service life is short.
Summary of the invention
Technical problem to be solved in the utility model is to provide the anti-full-glass solar energy heat pipe that splashes of a kind of employing silica sand, and simple in structure, Heat-collecting effect is good, long service life.
The technical scheme that the utility model technical solution problem adopts is: the anti-full-glass solar energy heat pipe that splashes of a kind of employing silica sand, comprise glass outer tube and glass inner tube, scribble absorber coatings on described glass inner tube outer wall, be set to vacuum in the interlayer of described glass outer tube and glass inner tube, vacuumize and be provided with heat-conducting medium in described glass inner tube, also comprise condenser pipe, described glass outer tube and glass inner tube end are melting sealed, form end face, described end face is connected with condenser pipe is melting sealed; Be provided with a small amount of silica sand bottom described condenser pipe and glass inner tube perforation, described glass inner tube.
As further improvement, the end between described glass outer tube and glass inner tube is provided with metal clasp.
As further improvement, described condenser pipe top is provided with metal cap.
Outer tube external diameter of the present utility model is Φ 58cm, and long 180cm, inner tube external diameter are Φ 47cm, long 177.5cm, and the condenser pipe external diameter can be Φ 47～Φ 58cm, long 12cm; Metal clasp is arranged at apart from inner and outer pipes port 3～4cm place.
In the utility model, the vacuum in the interlayer of glass outer tube and glass inner tube end is 5.0 * 10
-3Pa; Vacuum in glass inner tube is generally 1.0 * 10
-2Pa.
The beneficial effects of the utility model are: be comprised of three glass tubes, glass outer tube and glass inner tube top are melting sealed, form end face, and condenser pipe is connected with end face is melting sealed again, and namely easy fracture not, increase the service life; Be provided with a small amount of silica sand bottom glass inner tube, can prevent effectively that the medium that causes when inner tube is overheated from splashing and causing interior tracheal rupture, effectively increase the service life; Metal clasp is fixing glass outer tube and glass inner tube effectively, helps the melting sealed of glass outer tube and glass inner tube; The metal cap at condenser pipe top can accelerate heat radiation, and protection pore not received heat impacts.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Below in conjunction with accompanying drawing, the utility model is described further.
The specific embodiment
As shown in Figure 1, the anti-full-glass solar energy heat pipe that splashes of a kind of employing silica sand comprises that external diameter is the glass outer tube 1 of Φ 58cm, long 180cm, and external diameter is that glass inner tube 2 and the external diameter of Φ 47cm, long 177.5cm is Φ 50cm, the condenser pipe 6 of long 12cm.Scribble absorber coatings on glass inner tube 2 outer walls; End between glass outer tube 1 and glass inner tube 2 is provided with metal clasp 5, and is then that glass outer tube 1 and glass inner tube 2 ends is melting sealed with fixing glass outer tube 1 and glass inner tube 2, forms end face 4; This end face 4 is fused together with condenser pipe 6, and formation is tightly connected, and condenser pipe 6 connects with glass inner tube 2.Be set to vacuum in the interlayer of glass outer tube 1 and glass inner tube 2, vacuumize and be provided with heat-conducting medium length in glass inner tube 2 and be provided with a small amount of silica sand 3 in glass inner tube 2 bottoms; Also be provided with metal cap 7 at condenser pipe 6 tops.
