Description

Flexible reflector for increasing heat collection capacity of solar heat collector

Technical Field

The utility model belongs to the technical field of vacuum tube solar energy thermal-arrest, a flexible reflector panel for increasing solar collector thermal-arrest is related to.

Background

The vacuum tube solar heat collector comprises a heat preservation water tank, a vacuum heat collecting tube and a bracket. The empty heat collecting pipe collects photo-thermal heat and conducts the heat to a heat storage medium (water) in the water tank through microcirculation of floating hot water and sinking cold water, the water (or antifreeze) in the water tank transfers the heat away through a pipeline, and the heat is supplied to a bathing terminal or a heating terminal (floor heating, fan coil, radiating fin and the like) indoors for heating.

Most vacuum tube solar heat collectors in the current market adopt vacuum glass tubes with the diameter phi of 58mm, the lengths of the vacuum glass tubes are different, the distance between the vacuum glass tubes is 75-80 mm, and gaps of about 17-22 mm exist between the vacuum glass tubes. At about noon, sunlight is directly projected or is close to the direct projection period, and sunlight can be projected to the rear end of the heat collector through the gap between the vacuum tubes. At the moment, the actual lighting area of the vacuum tube heat collector is the sum of the outline lighting area and the clearance area between the vacuum tubes, and is smaller than the rated lighting area.

In tile roof installation solar engineering, the tread of an installer can cause cracks of tiles (tiny cracks are usually invisible, unobvious and neglected), and water leakage is caused.

Tile and flat roof roofs may leak water due to cracks in the tiles or flat roof after long structural fatigue caused by increased local area loads after installation of solar energy.

Therefore, how to solve the defects of the prior art is a subject of the present invention.

SUMMERY OF THE UTILITY MODEL

The utility model aims at having above-mentioned problem to current technique, having proposed a flexible reflector panel for increasing solar collector thermal-arrest, effectively combining butyl basic unit and aluminium foil, the actual daylighting area who has solved vacuum tube heat collector is less than rated daylighting area, causes the problem that the utilization ratio is low, the thermal-arrest performance is poor to the solar energy, has also solved the problem that the roofing of tiles leaks with the flat roof simultaneously.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a flexible reflector panel for increasing solar collector thermal-arrest, includes butyl base layer, aluminium foil, waterproof sealing layer one, waterproof sealing layer two, the butyl layer is pasted on the roofing floor through waterproof sealing layer one, the aluminium foil is pasted on butyl base layer through waterproof sealing layer two.

The butyl layer is a butyl rubber waterproof layer, in the field of building waterproofing, the butyl rubber is comprehensively popularized and used for replacing asphalt with an environment-friendly name, and the butyl rubber has good chemical stability and thermal stability and is most outstanding in air tightness and water tightness. Its permeability to air is only 1/7 for natural rubber and 1/5 for styrene-butadiene rubber, while its permeability to steam is 1/200 for natural rubber and 1/140 for styrene-butadiene rubber. The first waterproof sealing layer adopts a waterproof sealant special for buildings, the T-shaped base layer and the tile roof or the flat roof floor are fully stuck together under the condition that the roof floor is kept flat and fully dry and the roof floor does not contain dust, grease and other sundries, and the good effects of water leakage prevention of the roof and heat insulation are achieved. And the second waterproof sealing layer adopts a T-shaped base layer and special waterproof sealant for aluminum foil to effectively paste the aluminum foil on the T-shaped base layer. Through the test when the roofing be 3% ~ 4% to the reflectivity of sunshine when the roofing is black, be 6% ~ 8% to the reflectivity of sunshine when the roofing is white, use the utility model discloses to the reflectivity of sunshine for reaching 10% ~ 13%, will the utility model discloses install in vacuum tube heat collector below, effectively improved vacuum tube heat collector's collecting efficiency on the actual daylighting unit area to the aluminium foil is not so strong to the reflection of sunshine does not like specular reflection or refraction, and is similar to the diffuse reflection, makes sunshine diffuse to different directions, makes vacuum tube's side, the reflection of sunshine can both be received to the bottom, sets up and also can not cause light pollution to the city sky at the roof, the effectual environment that has protected.

Preferably, the thickness of the butyl base layer is 1.5-3.0 mm. The thickness setting of butyl basic unit is at 1.5 ~ 3.0mm, can not waste the material when making its performance reach the best requirement, and accords with the waterproof standard requirement of building and can not cause pressure and harm to the building itself, and possesses certain heat preservation, thermal-insulated effect.

Preferably, the aluminum foil has a thickness of 0.025 to 0.1 mm. The aluminum foil is too thin and is dried by wind for a long time, so that the service life is short, and the practical effect cannot be achieved. The excessive thickness of the aluminum foil can increase the use cost, but does not increase the corresponding beneficial effects.

Preferably, the aluminum foil is a semi-rigid foil. The aluminum foil can be divided into hard foil, semi-hard foil and soft foil according to the state, the hard foil is hard to cause poor plasticity, the construction and installation are inconvenient if the roof is fluctuated and protruded, and the soft foil is soft in texture, so that the aluminum foil is easy to damage and not durable in most application fields such as packaging, compounding, electrical materials and the like.

Compared with the prior art, the utility model has the advantages of it is following:

1. the utilization rate of solar energy is effectively improved, the sunlight can be reflected to the vacuum tube, and the heat collection efficiency of the vacuum tube solar heat collector is effectively improved;

2. the roof is effectively prevented from water leakage;

3. the heat preservation and insulation effect is good;

4. energy saving, environmental protection and no pollution;

5. convenient installation and simple use.
