Product Details

Product Introduction:

The Heat Pipe Solar Collector is built for exceptional performance and long-term reliability, featuring a closed-loop design that minimizes corrosion, eliminates leakage risks, and ensures extended service life. Its high-grade construction makes it ideal for both residential installations and demanding commercial solar thermal projects.

Using ultra-conductive metal heat pipes, the system ensures fast thermal transfer and impressive energy conversion, even during cold or overcast weather. Because the heat transfer process happens without water flow inside the pipes, it eliminates risks such as winter freezing or summer pressure bursts.

Adaptable to a wide range of architectural and engineering needs, this solar collector can be customized for size, angle, and layout. It is an excellent choice for centralized water heating systems in large facilities, such as hotels, hospitals, schools, and sports centers—providing stable, eco-friendly heating year-round.

Note:

(1) Rated efficiency:The total irradiance on the daylighting surface of the collector is 1000W/m²,and the temperature difference between the average temperature of the collector and the ambient air temperature is 50℃.Calculate the efficiency value of the solar collector according to the instantaneous efficiency equation of the collector's daylighting area.

(2) Rated power:The total irradiance of the collector lighting plane is 1000w/m²,and the collector power when the temperature difference between the average collector temperature and the ambient air temperature is 50°C is equal to the product of the rated efficiency and theday lighting area and 1000W/m² .
