Description

Solar energy heating bipass

Technical field

It the utility model is related to a kind of solar energy heating bipass.

Background technology

Solar energy can be converted to thermal energy by solar energy heat collection pipe, full to play heating effect to the medium in thermal-collecting tube The life requirement of sufficient people.Inner tube is integrally formed glass tube on existing market, it in easily expanding, causing after heated Pipe easily explosion, therefore in the prior art, the inner tube of thermal-collecting tube is one end closing, the form of one end open, and the length of inner tube Degree is shorter, increases the overall construction intensity of inner tube with this, reduces the probability of explosion.But under the configuration state, in thermal-collecting tube Medium, that is, air cannot effectively circulate, cause it not to be fully utilized effectively, and inner tube compared with section cause its to be situated between The amount of storage of matter is relatively low, therefore there is improved space.

Utility model content

In view of the deficiencies of the prior art, the utility model provides a kind of solar energy heating bipass.

To achieve the above object, the utility model provides following technical solution：

A kind of solar energy heating bipass, including outer tube and inner tube, said inner tube have pipe one and pipe two, one He of pipe Expansion of metal knot is sealed between pipe two, pipe one is connected backwards to the end part seal of one end of expansion of metal knot and outer tube, and pipe two is carried on the back It is tightly connected, is formed between the outer wall of inner tube and the inner wall of outer tube closed to the other end of one end of expansion of metal knot and outer tube Cavity；Some locating rings are equipped with the closed cavity, there is multiple chimbs and multiple concave edges, the chimb on the locating ring Be even circumferential spread configuration with concave edge, and the inner wall of chimb and outer tube against, the outer wall of concave edge and inner tube against.Pass through gold Belong to expansion knot, the probability that inner tube bursts because heated can be effectively reduced, i.e., when the temperature of inner tube is excessive, expansion of metal knot meeting Appropriate deformation is produced, to offset thermal expansion power, therefore ensure that the stability of inner tube, it is appropriate so as to which the length of inner tube is carried out Lengthening, to adapt to the demand used, at the same the stability of inner tube improve after can also realize the effects of inner tube both ends pass through openings, Realize that the medium in inner tube can sufficiently circulate, realize making full use of for the medium in inner tube；On the other hand, on locating ring Chimb and outer tube against, and concave edge and inner tube against further ensure that pipe one and pipe two relative to the steady of outer tube It is qualitative, that is, the vibration amplitude of pipe one and pipe two in outer tube is reduced, so as to reduce between pipe one, Guan Eryu expansion of metal knots Sealing-in point produce cracking probability.

Preferably, the locating ring has two, one of them is another close to the position of Guan Yiyu expansion of metal knot sealing-ins The position of a close Guan Eryu expansion of metal knot sealing-ins.The setting can effectively reduce the vibrations at two sealing-ins of expansion of metal knot Amplitude, so as to ensure the stability of sealing-in between expansion of metal knot and pipe one and pipe two, reduces the probability of sealing-in point cracking, from And it ensure that the stability of inner tube entirety.

Preferably, the chimb and concave edge are arc-shaped setting., can chimb and the preferable bullet of concave edge generation under the setting Property deformation, effective cushioning effect is played with the vibrations to inner tube, so as to ensure that pipe one, Guan Eryu expansion of metal knot sealing-ins Stability.

Preferably, the outer surface of the pipe one, pipe two and expansion joint is equipped with heat-sink shell.The heat-sink shell can play effectively Heat-absorbing action, to play the effect of heating to the medium in inner tube.

Brief description of the drawings

The schematic diagram for the solar energy heating bipass that Fig. 1 is provided by the present embodiment；

The schematic diagram for the locating ring that Fig. 2 is provided by the present embodiment.

Embodiment

The utility model solar energy heating bipass is further described by Fig. 1 to Fig. 2.

A kind of solar energy heating bipass, including outer tube 1 and inner tube 2, said inner tube 2 have pipe 1 and pipe 2 21, institute State and expansion of metal knot 3 is sealed between pipe 1 and pipe 2 21, pipe 1 is backwards to one end of expansion of metal knot 3 and the end of outer tube 1 Portion is tightly connected, and pipe 2 21 is tightly connected backwards to the other end of one end and the outer tube 1 of expansion of metal knot 3, inner tube 2 outer wall and Closed cavity is formed between the inner wall of outer tube 1, while the both ends of inner tube are run through, medium can free flow, this implementation in inner tube In example, the medium in inner tube is air, i.e., the present embodiment is heated the air of inner tube using solar energy, and the air after heating is had Effect is used for greenhouse heat supply；Some locating rings 4 are equipped with the closed cavity, there are multiple 41 Hes of chimb on the locating ring 4 Multiple concave edges 42, the chimb 41 and concave edge 42 are even circumferential spread configuration, and chimb 41 and concave edge 42 are arranged at intervals, and Adjacent chimb 41 and concave edge 42 is connected；The inner wall of chimb 41 and outer tube 1 is against as shown in Fig. 2, the both sides of chimb 41 have rib Side 411, it is actual against when, be the seamed edge 411 of 41 both sides of chimb with the inner wall of outer tube 1 against the position between two lateral edges 411 Vacantly, which is that chimb 41 and concave edge 42 are connected side；Concave edge 42 and the outer wall of inner tube 2 are against as shown in Fig. 2, recessed When having minimum on 42 421, it is actual against when, the minimum side 421 of concave edge 42 and the outer wall of inner tube 2 against, it is above-mentioned against Mode can both ensure stability of the inner tube 2 in outer tube 1, can also reduce locating ring 4 and inner tube 2 and the contact area of outer tube 1, with The transmission of heat is reduced, reduces the thermal losses in inner tube 2.The length of pipe 1 is more than the length of pipe 2 21, and pipe 2 21 Length can carry out size selection according to needed for actual utilization, therefore under the action of expansion of metal knot 3, the length of inner tube 2 Two meters or more are can reach, and the coefficient of expansion is good, is not easy to burst.

Further, the locating ring 4 has two, one of them is close to pipe 1 and the position of 3 sealing-in of expansion of metal knot Put, i.e., the locating ring 4 is socketed on pipe 1, and from 4-8cm at 3 sealing-in of pipe 1 and expansion of metal knot, another is close to pipe two 21 with the position of 3 sealing-in of expansion of metal knot, i.e. the locating ring 4 is socketed on pipe 2 21, from 3 sealing-in of pipe 2 21 and expansion of metal knot Locate 4-8cm.
