Abstract
The utility model relates to a solar water heater, in particular to a high efficiency solar water heater which comprises an insulation water tank, a vacuum heat colleting pipe, a support and a connecting pipeline. The vacuum heat colleting pipe includes an outer pipe, an inner pipe and a selective absorption coating which is arranged outside the inner pipe. The high efficiency solar water heater is characterized in that the outer pipe is in an annular shape, the inner pipe is in an ellipse shape, and the separation distance is kept between the inner pipe and the outer pipe. Because the inner pipe of the vacuum heat colleting pipe is in the ellipse shape, the sunlight can shoot at right angles into two sides of the inner pipe, and two sides of the heat collecting pipe can absorb more solar energy. Accordingly, the heat efficiency of the whole solar water heater is greatly improved.
Description
Technical field
The utility model is a kind of solar water heater, particularly a kind of efficient solar water heater.
Background technology
Solar water heater is a kind of device that utilizes solar energy cold water to be changed into hot water.Solar water heater is made up of attemperater, vacuum heat collection pipe, support, connecting pipe etc., solar energy is converted to heat energy mainly rely on vacuum heat collection pipe.The structure of vacuum heat collection pipe comprises outer tube, interior pipe, coating for selective absorption, and outer tube and interior pipe are two concentric pipes, and coating for selective absorption is the outside of pipe in being coated in, and water flows in the inside of interior pipe.The vacuum heat collection pipe of this concentric-ring pattern, there is following defective: when shining upon on thermal-collecting tube, because interior pipe is round, so interior pipe both sides almost become tangent state with sunshine, how many sunshines are the both sides of thermal-collecting tube in fact absorbed less than, cause the thermal efficiency of whole solar water heater to be had a greatly reduced quality.
Summary of the invention
The purpose of this utility model is to have the not high defective of the solar water heater thermal efficiency now in order to overcome, and the interior pipe of inventing a kind of vacuum heat collection pipe is oval-shaped efficient solar water heater.
The novel purpose of this use realizes as follows: described efficient solar water heater, form by attemperater, vacuum heat collection pipe, support, connecting pipe, vacuum heat collection pipe comprises outer tube, interior pipe and coating for selective absorption, coating for selective absorption is located at interior tube outside, it is characterized in that: described outer tube is a round tube, interior pipe is oval pipe, maintains spacing between interior pipe and the outer tube.
Good effect of the present utility model is as follows: because the interior pipe of vacuum heat collection pipe is oval, so sunshine can direct projection arrive interior pipe both sides, make the both sides of thermal-collecting tube can absorb more solar energy, this has just improved the thermal efficiency of whole solar water heater greatly.
Description of drawings
Fig. 1 is the utility model structured soil
Fig. 2 is the vacuum heat collection pipe cross-section structure
Among the figure: 1 attemperater, 2 vacuum heat collection pipes, 3 supports
Pipe in 4 connecting pipes, 5 outer tubes 6
7 coating for selective absorption
Concrete true mode
As shown in Figure 1, described efficient solar water heater, form by attemperater 1, vacuum heat collection pipe 2, support 3, connecting pipe 4, vacuum heat collection pipe 2 comprises outer tube 5, interior pipe 6 and coating for selective absorption 7, pipe 6 outsides in coating for selective absorption 7 is located at, it is characterized in that: described outer tube 5 is round tube, and interior pipe 6 is an oval pipe, maintains spacing between interior pipe 6 and the outer tube 5.
Because the interior pipe of vacuum heat collection pipe is oval, so sunshine can direct projection arrive interior pipe both sides, make the both sides of thermal-collecting tube can absorb more solar energy, this has just improved the thermal efficiency of whole solar water heater greatly.
