Product advantage

     Solar energy (Solar) generally refers to the Sun's radiant energy  which is used as the modern general power generation. The water tank adopts stainless steel SUS304 food grade material, Corrosion resistance and durable .The brackets Using aluminum alloy material,USES the word "people" streamlined support, and combine the water tank, strong and durable .The vacuum tube is made of high quality high borosilicate, hard glass production,Good light transmittance,Heat faster Heat preservation is better. Our company can produces its own water tank bracket and vacuum tubes,Its products over the years committed to technology innovation,So the quality and service guaranteed and there are quite a preferential price.So many advantages is your best choose!

 

 

 

How it works

    The design of this type uses the all-glass evacuated solar collector tubes as the heat absorb element. The high vacuum degree of the clearance between the outer and inner tube can reduce the heat emission which caused by convection and conduction to a very low level. All-glass evacuated tube transfers sun energy into heat energy by high absorption rate and low emittance rate of layer films. Depend on the different density between the hot water and the cold water, a cycle created in the tube which hot water ascending and cold water descending status. Keeping natural circulation like this, the water in the tank will be heated. Flat plate collectors are an extension of the basic idea to place a collector in an 'oven'-like box. Here, a pipe is connected to the water tank and the water is circulated through this pipe and back into the tank. The water tank is now outside the collector that only contains the pipes. Since the surface-to-volume ratio increases sharply as the diameter of a pipe decreases, most flat-plate collectors have pipes less than 1 cm in diameter. The efficiency of the heating process is therefore sharply increased. The design of a flat-plate collector therefore typically takes the shape of a flat box with a robust glass top oriented towards the sun, enclosing a network of piping. In many flat-plate collectors the metal surface of the pipe is increased with flat metal flanges or even a large, flat metal plate to which the pipes are connected. Since the water in a flat-plate collector usually reaches temperatures much higher than that of an ICS, the problem of radiation of heat back to the environment is very important, even though a box-like 'oven' is used.

Q:Superconducting heat pipe solar collector temperature ok
Heat pipe collector can be used under the conditions of minus 50 ℃, can withstand pressure operation, but the heat pipe condensation side (heating side) surface area is only one hundred percent of the vacuum tube, easy to scale, heat transfer effect as vacuum tube, and the use of direct effect By the heat pipe itself, the quality and life of the impact of some heat pipe quality decline and attenuation problems,
Q:Is solar collector directly using solar energy?
As the solar light is more dispersed, we must try to put it together, so the collector is a key part of the use of solar energy devices.
Q:What is the principle of thermal conversion of solar collectors?
The basic principle is to collect solar radiation can use the greenhouse effect to heat objects and access to heat, such as plastic film, greenhouses, greenhouses and so on. At present, there are two kinds of solar energy collection devices: one is a flat type collector, such as solar water heaters, etc .; the other is a focus collector, such as reflective solar cookers, high temperature solar furnace.
Q:Solar collectors and tank water can not cycle what is the reason
Pipe clogged. If the exclusion of the other two cases, then the possibility of a large pipe block, including the pipeline frozen, debris blockage are possible, if the pump is easier to burn the pump, need special attention.
Q:With the tonnage of solar collectors and air to hot water which power consumption
resulting in no hot water in the rain and snow weather; and air to hot water works relative It is not affected by the sunshine, theoretically can be used throughout the year.
Q:How can solar collector system prevent wind?
The collector must be provided with proper wind protection, bolted or secure. Other components of the solar thermal water system are affected by the wind may cause damage or affect the normal operation of the system,
Q:Condensation type solar collectors and non-concentrating heaters
solar collectors can be divided into two types. Condenser collector A condenser is a solar collector that uses a reflector, a lens, or other optics to change the direction of solar radiation entering the lighting port and converge to the heat absorber
Q:Flat solar collector how, flat solar collector working principle introduced
The installation of the system search should ensure safety and functionality while taking into account the combination with the building.
Q:Where is the solar collector installed in the building?
Different local requirements and horizontal angle is not the same, in the north and the horizontal angle needs a little bigger.
Q:Flat solar collector is a good blue film, or good black chrome? It is best to specify.
The absorption ratio α and the emission ratio ε of the black chromium coating are 0.93-0.97 and 0.07-0.15, respectively, and α / ε is 6 to 13, and has excellent spectral selectivity.
