Specifications

Flat panel solar thermal collector 
Low iron tempered glass 
Core: all Copper, ultrasonic welding. 
Coating: black chrome

Flat panel solar thermal collector 
consist of glazed, flat, dark surfaced absorber plate which contains copper tubing. The Plate absorbs incoming solar heat energy and the casing minimises heat loss. A fluid is circulated through the tubing and this fluid heats up as it passes by the absorber plate.


Feature:

1) Absorptance: ≥95%±2%. 
2) Material:thickness:low iron rohbic tempered glass x thickness: 3.2mm. 
3) Glass sheet size: 1988×988 mm. 
4) Glass transmittance: 87%~91%.  
6) Insulation material:Rock wool. 
7) Back sheet material: Zincification plate0.3mm; embosseo Aluminum0.5mm. 
8) Cross area: 2 m2. 
9) Heat absorber area: 1.8 m2. 
10) Fluid content: 2L. 
11) Maximumpressure: 1 Mpa. 
12) Operation temperature: -40~150°C.


Flat Plate Collectors

Flat plate collectors are the most common solar thermal collectors. They are most appropriate for low temperature applications, such as domestic hot water heating. Flat plate series water heaters maximizes solar heat gain, minimizes heat losses, and provides for the most efficient heat transfer from absorber plate to tube.

Flat Plate Solar Collectors are a glazed collectors which

feature a coating which maximizes heat absorption, aluminum framing which can withstand heavy weight and is weather resistant, and interior fiberglass insulation which allows for greater efficiency. The combination the latest energy efficiency technology and a strong heat exposure allow for optimal heat transfer and makes these lights the highest in BTU performance.

An important asset of flat plate solar collectors is their versatility. Their excellent efficiency makes them also suitable for the operation of larger systems for commercial or public use. Solar Flat Plate collectors are typically recommend for use in warmer climates simply because they are designed with larger absorber areas that are not insulated from the colder weather.

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:What is the principle of thermal conversion of solar collectors?
The most common solar collectors are non-concentrating flat type collectors. Its heat absorber body is basically flat shape, the area of heat absorption and the lighting area is approximately equal, its structure as shown in Figure (a) is the use of greenhouse effect of non-concentrating type collector. Enriched CO2 in the greenhouse can improve the greenhouse effect. Condenser type collector using the principle of focusing, that is, the use of light reflection and refraction principle, the use of reflectors or refractors to change the direction of the sun, the sun focused on the heat sink in the small area of the heat absorber, increase the unit area Of the radiation intensity, so that the collector to obtain a higher temperature.
Q:What is the working principle of flat solar collectors?
The basic working principle of flat solar collectors is very simple. Generally speaking, the sun through the transparent cover plate to the surface coated with absorbent layer on the heat absorber, in which most of the solar radiation can be absorbed by the absorber, into heat, and to the fluid channel in the working fluid.
Q:The characteristics of flat solar collectors
Therefore, in the same lighting area and daylight intensity, flat solar water heater daily average efficiency is generally higher than the vacuum tube solar water heater daily average efficiency of more than 6%. Three is a good pressure performance.
Q:How can solar collector system prevent wind?
Solar collectors are the core components of the solar thermal system. Solar collectors absorb light from solar radiation, generate a lot of heat, provide a steady stream of power, it is like people's "heart", the heart once stopped beating, people Can not live, then the solar collector once damaged, the hot water system will lose their vitality
Q:Condensation type solar collectors and non-concentrating heaters
according to whether to track the sun, according to whether there is a vacuum space; According to the collector type of heat transfer, the solar collectors can be divided into two types. Liquid collector air collector according to enter the mouth of the solar radiation is to change the direction of classification According to the solar radiation into the lighting port to change direction,
Q:Flat solar collector how, flat solar collector working principle introduced
Set up reliable lightning protection measures. 5) The storage tank base must be located on the load-bearing wall (beam) of the building and reserved for fixing parts. The gap between the embedded part and the base, the application of fine stone concrete filling dense. 6) storage tank application anchor bolts and foundation connection firmly.
Q:Where is the solar collector installed in the building?
There are flat-plate collectors and vacuum tube collectors, as well as medium-high temperature trough collectors in different forms, the installation site requirements are not the same; but generally according to geographical location, towards the basic south.
Q:The introduction of flat solar water heater
The collector and the water tank are separated from each other. The collector can be flexibly installed on the roof, skylight, balcony or wall, and it is not limited by the position and has reached the perfect combination with the high-rise building and the environment.
Q:Flat solar collector is a good blue film, or good black chrome? It is best to specify.
However, the current plating black chrome process, the current density (15 ~ 200A / dm2), the solution conductivity is poor, plating will produce a lot of Joule heat, cooling and ventilation need to maintain normal production. In addition, the black chrome plated in the non-copper pieces, you need to pre-copper, and then plating bright nickel, and finally black chrome, the higher production costs.
