Abstract
The utility model relates to the technical field of solar energy-utilizing equipment, in particular to a unit for improving the heat-collecting efficiency of solar vacuum tubes. The unit consists of two sunlight reflectors positioned behind the solar vacuum tubes, and is characterized in that the two sunlight reflectors are mounted at the same height as the solar vacuum tubes, and make an includedangle with each other; and the included angle between the two sunlight reflectors ranges from 96 degrees to 106 degrees. The utility model has the advantages of low cost, good effect, high universality and easy popularization.
Description
(1) technical field
The utility model relates to technical field of solar energy utilization equipment, particularly a kind of device that improves the solar energy vacuum tube collecting efficiency.
(2) background technology
Solar energy vacuum tube heat collector has occupied about 80% the market share with its particular performances in Chinese field of solar collectors, use more and more wider.At present, the solar energy vacuum tube heat collector thermal-arrest only depends on the front in the face of the sun to absorb the sunshine thermal-arrest, and this has just limited its caloric receptivity, causes whole heat absorption efficiency not high, has also caused back to the wasting of resources of the heat collecting vacuum pipe of sun one side.
(3) summary of the invention
The utility model provides a kind of device that effectively utilizes sunshine to improve the solar energy vacuum tube collecting efficiency in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of device that improves the solar energy vacuum tube collecting efficiency, comprise the two surface sunlight reflecting plates that are positioned at the solar energy vacuum tube back, its special character is: the setting height(from bottom) of two surface sunlight reflecting plates is the same with solar energy vacuum tube high, has angle between the two surface sunlight reflecting plates.
Effect was better when the angular range between the two surface sunlight reflecting plates of the present utility model was 96 °-106 °.
Because the particular requirement that solar energy vacuum tube heat collector is installed all will be reserved 50 millimeter even bigger space between vacuum tube and the vacuum tube, this just may for utilizing vacuum tube back side thermal-arrest to provide.
The utility model is in the solar energy vacuum tube heat collector back, setting height(from bottom) is the same with vacuum tube collector high, have two surface sunlight reflecting plates of certain angle, sunshine sees through the space between the tube and tube, shine on the sunshine reflecting plate, the reverberation comprehensive function shines the back side of vacuum tube collector, make the solar energy vacuum tube back side absorb sunshine, solar energy vacuum tube two sides heat absorption like this, solar energy vacuum tube heat collector heat absorption efficiency than only positive heat absorption has improved more than 30%, and cost has only increased about 5%.
The utility model cost is low, and is effective, and highly versatile is beneficial to popularization.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1 solar energy vacuum tube, 2 sunshine reflecting plates, 3 angles.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises that the setting height(from bottom) of two surface sunlight reflecting plates, 2, the two surface sunlight reflecting plates 2 that are positioned at solar energy vacuum tube 1 back is the same high with solar energy vacuum tube 1, has angle 3 between the two; Angle 3 scopes between the two surface sunlight reflecting plates 2 are 96 °-106 °.
It is as follows to compare test between the A example as B example of the present invention and prior art:
A example: with the solar water heater that 15 45*1500 vacuum tubes are made, heat collector surface 1475*1500,95 millimeters of tube and tube centre-to-centre spacing;
B example: with the solar water heater of 15 45*1500 vacuum tubes making, heat collector surface 1475*1500,95 millimeters of tube and tube centre-to-centre spacing, the back has installed two blocks of high 150 millimeters, wide 962 millimeters solar energy reflection plates (width multiply by angle according to 1475 and calculates, and angle effect between 96 to 106 degree is best) additional.
The A example has been measured respectively under identical external condition with the B example, adds the water of uniform temp, the weight of the hot water that produces when in the identical time, being increased to identical temperature, and experimental result sees Table 1.
Table 1
By 1500 millimeters of solar energy vacuum tube heat collector back setting height(from bottom)s, wide 962 millimeters, angle 3 is two surface sunlight reflecting plates 2 of 100 degree, sunshine sees through the space between the tube and tube, shine on the sunshine reflecting plate 2, the reverberation comprehensive function shines solar energy vacuum tube 1 back side, make solar energy vacuum tube 1 back side absorb sunshine, like this, the heat absorption of solar energy vacuum tube 1 two sides, solar energy vacuum tube heat collector heat absorption efficiency than only positive heat absorption has improved more than 30%, has good social benefit.
Claims (2)
1. device that improves the solar energy vacuum tube collecting efficiency, comprise the two surface sunlight reflecting plates (2) that are positioned at solar energy vacuum tube (1) back, it is characterized in that: the setting height(from bottom) of two surface sunlight reflecting plates (2) is the same high with solar energy vacuum tube (1), has angle (3) between the two surface sunlight reflecting plates (2).
2. the device of raising solar energy vacuum tube collecting efficiency according to claim 1 is characterized in that: angle (3) scope between the two surface sunlight reflecting plates (2) is 96 °-106.
