Description
Technical field
The utility model is related to a kind of evacuated collector tubes, more particularly, to a kind of improved evacuated collector tube, belong to the sun
It can technical field of heating.
Background technology
At present, well known evacuated collector tube is applied on solar thermal collector mostly, and the vacuum tube is by with vacuum interlayer
Glass tube walls and hollow cavity are formed.Water is placed in the tube chamber of vacuum tube and is contacted with inside pipe wall, when there is sunlight, vacuum
Water in pipe cavity is heated up, you can provides a user hot water.However water is few or even anhydrous in the vacuum tube, and vacuum
Pipe and the adstante febre under sunlight, since glass is difficult to the cold and hot fierceness of bearing temperature when cold water enters vacuum tube cavity
Variation be easy for bombing, as long as and a vacuum pipe from breakage whole system cannot be run in system, so existing glass material
The vacuum tube collector of matter is far from its due effect of performance, therefore it is necessary to the prior art is improved and is created completely
Newly.
Although existing Chinese patent application CN201120308642.6 discloses a kind of evacuated collector tube and vacuum collector is true
Empty set heat pipe and vacuum collector primarily to overcome vacuum tube occur bombing so that influence system operation the defects of, but should
Type has the following problems：
1. low heat exchange efficiency
Since its operation principle is to form free convection driving force by the temperature difference of vacuum tube in itself, make water in thermal branch pipe
Interior flowing, and since the thermal branch pipe draw ratio is very big, so that the flow resistance of free convection is very big, branch pipe Nei Shui and pipe
The heat exchange efficiency of wall is relatively low.
2. safety in utilization is poor
When water is few or even anhydrous in vacuum tube, and vacuum tube adstante febre under sunlight, once cold water enters vacuum
Bombing is easy for since glass is difficult to the cold and hot fierce variation of bearing temperature during pipe cavity, as long as and a vacuum tube is fried in system
Pipe whole system cannot be run, it is possible to be sent out the phenomenon that vacuum tube during use has " thermal explosion " or " cold quick-fried "
It is raw.
If there is a vacuum tube to burst, the water in water tank can be released from the cut, and whole system is caused to paralyse.
3. vacuum tube easily abjection or easy to aging
On the one hand due between the liner of adjacent or opposite vacuum tube and coupling device without fixed connection apparatus, it is true
The operation principle of blank pipe is to form free convection driving force by the temperature difference of vacuum tube in itself, and water is made to be flowed in thermal branch pipe,
And since the thermal branch pipe draw ratio is very big, so that the flow resistance of free convection is very big, therefore each vacuum tube is easy
It comes off, and then influences the safety and reliability entirely to work；On the other hand due in the outer of thermal branch pipe outer end opening
Sealing ring is equipped between wall and the inner wall of vacuum tube, therefore, the design of the structure easily causes between thermal branch pipe and vacuum tube
Easy leak, sealing ring are easy to aging, and service life greatly shortens.
The heat exchange efficiency of water and tube wall is relatively low, vacuum tube easily bursts in order to overcome in existing branch pipe, causes whole
Easy leak, sealing ring are easy to aging between a systemic breakdown and thermal branch pipe and vacuum tube, and service life greatly shortens and very
Blank pipe holds caducous many shortcomings and deficiencies, and the utility model provides a kind of improved evacuated collector tube and vacuum collector,
Bear that outer impact energy force difference, heat production water are low, installation is complicated, easy to aging, service life is short, easily come off to solve the prior art
The technical problems such as leakage.
Therefore, it is improved that one kind that a kind of construction is simple, fixed, reliable operation and service life are longer need to be developed
Evacuated collector tube is the key that solve above-mentioned technical problem.
