360 reflecting CPC- reflector increases 15% heat-collecting efficiency

In order to increase the efficiency of the vacuum tube col lector, a highly reflecting and weather proof CPC-reflector ( Compound Parabolic Concentrator ) is placed behind the vacuum tubes . This special mirror geometry ensures that even at unfavorable irradiation angles direct and diffuse sunlight will fall onto the absorber. This CPC-reflector made in Germany can improve the heat-collecting efficiency by 15%.

The CPC-reflector is produced from a metal sheet with protective coating using accurate roll forming technology and enamel mirror technology. The special coating on the mirror is a valid anti – corrosion proces sing for the reflect or.

Due to unique fastening technology the CPC-reflector can be exchanged without using tools .

Vacuum tube collector without CPC-reflector

for water, space and process heating and solar cooling with 90oC ~ 130oC temperature requirement.

The vacuum tube collect or without CPC-reflector has high energy yield due to special collector structure that contains vacuum tubes with highly selective absorber layer, U-shaped copper pipes inside vacuum tube for heat transport and aluminum heat transfer plate between copper pipes and vacuum tubes .

Compared to the series with CPC-relfector, this type of collector is specially developed for specific installation area and climate environment that needs to be protected against strong wind or heavy snow.

Advantages and benefits

  • Rapid thermal conductivity.
  • Operating at minimum ambient temperature of – 30oC to maximum operating temperature of 90oC.
  • Season independent operation depending on the heat transfer medium.
  • High flexibility due to the different widths and lengths of the collectors.
  • Pressurized and non-pressurized operation.
  • Anti-freezing medium in the solar circulaion loop to ensure hot water on cold days.
  • Short installation times due to complete preassembled collectors.
  • Manageable module sizes for a high performance.
  • Flow and return pipes may be filled on the left or the right side of the manifold.

Heat pipes for minimum ambient temperatures of -30oC
The vacuum heat pipe technology uses the maximum fraction of solar irradiation at minimum ambient temper atures of – 30oC and maximum operating temperatures to 90oC.

Sunlight is captured by the coated vacuum tubes which absorb the radiation as heat and conduct it to the heat pipe through aluminum heat trans fer plate. The heat trans fer medium inside heat pipes vaporizes and the vapor rapidely rises to the top. releasing the heat and condenses to for mali quid and returns to the pipe bottom where it evaporated again and repeats in cycle.

With high purity copper material , the heat pipe features excellent corrosion resistance and can stand high temperature over 250oC. Due to rapid heat conductivity evacuated heat pipe collectors are suit able for solar thermal applications in cooler areas with low ambient temperatures. *

* actual operating ambient temperature is in dependence on respective heat trans fer medium.
