Abstract
The utility model discloses a solar energy vacuum tube, including an external tube, which is characterized in that the external tube contains an internal tube inside, the two terminals of the internal tube have openings, the terminal ends of the external and internal tubes are in seal connection, a sealed space is formed between the external and internal tubes and at least one scalable section is arranged on the internal tube. The utility model vacuum tube is conducive to the flow of heat absorption media, which is characterized by none foreign substances and high heat collecting efficiency. The scalable section of the vacuum tube makes it difficult to break the tube.
Description
Technical field
The utility model belongs to technical field of solar, relates to a kind of solar energy vacuum tube.
Background technology
Solar water heater is with safety, convenient, advantage such as pollution-free is widely used, solar vacuum-tube water heater is subjected to consumer's welcome deeply with its high efficiency, the primary structure of solar vacuum-tube water heater is the vacuum tube of installing on water tank in groups, vacuum tube is an end opening, the sealing of one end, wherein openend is inserted in the storage tank, and sealed end is installed on the tailstock, fix by support, not connected between the vacuum tube, its working method is single work, the water heating of the internal pipe of heat collecting vacuum pipe, because the proportion difference of hot and cold water, produce circulation, because single work, water circulates in the interior pipe of every vacuum tube, it is not smooth to circulate, the heat energy exchange of can not effectively flowing, overheated also can the causing of vacuum tube broken, and causes vacuum tube to damage, if contain impurity in the water, then sink to the pipe end easily, can not impurity be taken away, can cause water pollution for a long time by flowing, easy incrustation in the vacuum tube descends the vacuum tube collecting efficiency simultaneously.
The utility model content
The purpose of this utility model provide a kind of easy for installation, both ends open, solar energy vacuum tube.
The further purpose of the utility model provides a kind of difference solar energy vacuum tube that the vacuum tube that brings breaks that expands with heat and contract with cold of eliminating.
The utility model is realized above-mentioned purpose by the following technical solutions: a kind of solar energy vacuum tube, comprise outer tube, and be set with interior pipe in the outer tube, interior pipe both ends open, be tightly connected between outer tube and the inner tube face, form confined space between outer tube and the interior pipe, interior pipe is provided with one section telescopic section at least.
An end of pipe in telescopic section is arranged on.
Telescopic section is a bending tube.
Telescopic section is the serpentine pipe.
Telescopic section is a spiral element.
Telescopic section be the middle part diameter greater than the two ends diameter " in " the font pipe.
" in " the font pipe is better by elasticity, heat proof material is made, two ends are connected with the interior seal of tube respectively.
Vacuum tube both ends open of the present utility model, two ends can be inserted in tube connector or the storage tank respectively, form the peripheral passage of a vacuum tube-storage tank-tube connector-vacuum tube, by the different characteristic of the cold and hot proportion of water itself, hot water upwards flows, cold water flows downward, hot water upwards flows into storage tank in the vacuum tube, and the cold water of storage tank bottom enters into vacuum tube by tube connector, behind the absorption heat, enter storage tank again, move in circles.The good fluidity of water, the heat exchange efficiency height makes water in the storage tank improve temperature in the short time, and simultaneously, impurity is difficult for being deposited in the vacuum tube in the water, has improved the collecting efficiency of vacuum tube.In addition, vacuum tube is generally made by glass, during tubulation, the inner and outer pipe two ends directly link together, because interior pipe has applied heat-absorbing material, make the coefficient of expansion difference of inner and outer pipe, the difference of expanding with heat and contract with cold causes breaking of inner and outer pipe easily, the interior pipe of the utility model vacuum tube is provided with telescopic section, leans on the distortion of telescopic section to absorb the different variation of expanding with heat and contract with cold and bringing of inner and outer pipe, can not cause breaking of vacuum tube.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of second kind of embodiment of the present utility model;
Fig. 3 is the structural representation of the third embodiment of the present utility model;
Fig. 4 is the structural representation of the 4th kind of embodiment of the present utility model.
The specific embodiment
As Fig. 1,2,3, solar energy vacuum tube shown in 4 comprises outer tube 1, pipe 2 in being set with in the outer tube 1, interior pipe 2 both ends opens, be tightly connected between outer tube 1 and interior pipe 2 end faces, form confined space between outer tube 1 and the interior pipe 2, the end of interior pipe 2 is provided with one section telescopic section 3, telescopic section 3 is a bending tube, in pipe 2 make by glass, it is tubular that telescopic section 3 is directly at one end made bending, bending tube can be " S " pipe, spiral element or other form bending tubes, another kind of mode for be equipped with at interior pipe 2 one ends the middle part diameter greater than the two ends diameter " in " font pipe 3, " in " font pipe 3 can be better by elasticity, heat-resisting material is made, for example metallic copper, thin slices such as stainless steel are made, " in " font pipe 3 two ends insert in pipe 2 and seal by fluid sealant.Being provided with of telescopic section can absorb expanding with heat and contract with cold of inner and outer pipe 1,2 and bring different the variation, reduces breaking of vacuum tube.
