Abstract
The utility model discloses a kind of solar water heater vacuum-tube, including cover glass tube and inner glass tube, it is vacuum between cover glass tube and inner glass tube that cover glass tube and inner glass tube, which are two concentric circles glass tubes,；Inner glass tube is shorter in length than cover glass tube, and inner glass tube both ends are equipped with the pipeline of the water tank for being connected to solar water heater, length of the length of inner glass tube plus the length of its both ends pipeline and equal to cover glass tube；Utility model has the advantages that the technical program replaces original part inner glass tube with the pipeline at inner glass tube both ends, greatly reduce the contact area of inner glass tube both ends and water tank and air, to reduce the area of heat conduction and heat radiation, greatly improve heat preservation duration and heat insulation effect, the outer surface of inner glass tube is divided into two regions simultaneously, half, for keeping the temperature, greatly improves the heat insulation effect of vacuum tube and does not influence heat conduction efficiency for heat transfer half.
Description
Technical field
The utility model relates to a kind of solar water heater, especially a kind of solar water heater vacuum-tube.
Background technique
In today that global energy situation is nervous, climate warming seriously threatens economic development and people's life health, the world
New energy substitution strategy is all being sought by each state, obtains superiority in the hope of sustainable development and in development in the future.Too
Sun can with its cleaning, continually, safety etc. significant advantages, become focal point.In the development of solar energy industry, solar energy
The heat utilization switch technology of water heater is undoubtedly the most mature, but heating method has the following problems: on the one hand, in vacuum
When there is no water in pipe, once there is cold water entrance, there are problems that bombing；On the other hand, the heat of vacuum tube is very big, it is easy to go out
Existing scale, to influence heating effect.
Utility model content
The purpose of this utility model provides a kind of solar water heater vacuum-tube of good heat insulating, solves above-mentioned existing skill
One or more in art problem.
In order to solve the above technical problems, the technical solution of the utility model are as follows: a kind of solar water heater vacuum-tube, wound
New point is: including cover glass tube and inner glass tube, cover glass tube and inner glass tube are two concentric circles glass tubes, cover glass tube
It is vacuum between inner glass tube；Inner glass tube is shorter in length than cover glass tube, and inner glass tube both ends are equipped with for being connected to too
The pipeline of the water tank of positive energy water heater, length of the length of inner glass tube plus the length of its both ends pipeline and equal to cover glass tube
Degree；
The 180 degree cambered surface of the direct sunlight of inner glass tube is equipped with absorber coatings, the 180 degree cambered surface of the backlight of inner glass tube
It is equipped with insulating layer, the thickness of insulating layer is twice of the thickness of absorber coatings.
In some embodiments, the difference of the radius of the radius and inner glass tube of cover glass tube is 1.6cm.
In some embodiments, the difference of the radius of the holding of cover glass tube and inner glass tube both ends pipeline is 4cm.
Utility model has the advantages that the technical program replaces glass in original part with the pipeline at inner glass tube both ends
Glass pipe, the very big contact area for reducing inner glass tube both ends and water tank and air, to reduce the face of heat conduction and heat radiation
Product greatly improves heat preservation duration and heat insulation effect, while the outer surface of inner glass tube is divided into two regions, and half is used
In heat transfer half for keeping the temperature, greatly improves the heat insulation effect of vacuum tube and do not influence heat conduction efficiency.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of solar water heater vacuum-tube of the utility model.
Fig. 2 is a kind of cross-sectional view of solar water heater vacuum-tube of the utility model.
Specific embodiment
With reference to the accompanying drawings of the specification, the utility model is described in more detail.
A kind of solar water heater vacuum-tube as depicted in figs. 1 and 2, including cover glass tube 1 and inner glass tube 2, cover glass
Glass pipe 1 and inner glass tube 2 are two concentric circles glass tubes, are vacuum between cover glass tube 1 and inner glass tube 2；Inner glass tube 2
It is shorter in length than cover glass tube 1,2 both ends of inner glass tube are equipped with the pipeline 3 of the water tank for being connected to solar water heater, interior glass
Length of the length of pipe 2 plus the length of its both ends pipeline 3 and equal to cover glass tube 1；The 180 of the direct sunlight of inner glass tube 2
It spends cambered surface and is equipped with absorber coatings 21, the 180 degree cambered surface of the backlight of inner glass tube 2 is equipped with insulating layer 22, the thickness of insulating layer 22
Degree is twice of the thickness of absorber coatings 21.
In some embodiments, the difference of the radius of the radius of cover glass tube 1 and inner glass tube 2 is 1.6cm.
In some embodiments, the difference of the radius of 2 both ends pipeline 3 of the holding of cover glass tube 1 and inner glass tube is 4cm.
Utility model has the advantages that the pipeline 3 at the technical program 2 both ends of inner glass tube replaces in original part
Glass tube 2, the very big contact area for reducing 2 both ends of inner glass tube and water tank and air, to reduce heat conduction and heat radiation
Area, greatly improve heat preservation duration and heat insulation effect, while the outer surface of inner glass tube 2 is divided into two regions,
Half, for keeping the temperature, greatly improves the heat insulation effect of vacuum tube and does not influence heat conduction efficiency for heat transfer half.
The protection scope of the present invention is defined by the appended claims and their equivalents.The above is only this
The preferred embodiment of utility model, it is noted that those skilled in the art, created not departing from the utility model
Under the premise of design, some similar deformation and improvement can be made, these also should be regarded as the protection scope of the utility model
Within.
