High Performance Flat Plate Collector

High-performance flat plate collectors are efficient devices for utilizing solar energy, consisting of core components such as absorber plates, transparent covers, insulation layers, and casings. They absorb solar radiation through the absorber plate and convert it into thermal energy. The transparent cover reduces heat loss through radiation and convection, while the insulation layer further minimizes heat conduction loss, thereby efficiently heating the internal flowing working fluid (such as water or air). Compared with traditional flat plate collectors, they have advantages in flow channel design, insulation materials, absorber film layers, and structural design, resulting in higher heat collection efficiency, lower heat loss, and better overall performance. They are widely used in solar water heating systems, building heating, and other fields, and are one of the key equipment for achieving efficient utilization of solar energy.

Application Scenarios

Domestic hot water/heating: Families need stable hot water supply and winter heating guarantee, with a population size of mostly 3-5 people, and are sensitive to energy costs. The collector can adapt to different 户型 heating areas and meet the comfort needs of home life.
Swimming pool constant temperature: Whether it is a private pool or a small commercial pool, it needs to maintain a comfortable water temperature of 26-28℃, and the environment is mostly humid. The collector can adapt to this condition and match different pool sizes to achieve stable water temperature.
Hotel, hospital, office building hot water/heating: With dense personnel, the demand for hot water and heating is large and concentrated, and there are high requirements for equipment stability and installation efficiency. The collector can form a large-scale system, be quickly installed, and operate stably for a long time.
Industrial preheating: There are various processes in industrial production that require preheating materials or media. The site environment is complex, and there are requirements for equipment durability and flexibility in heat collection scale. The collector can meet the preheating needs of different production scales.
Agricultural drying: In agricultural production, it is necessary to dry agricultural products such as grains, fruits and vegetables, and Chinese medicinal materials. There are high requirements for the stability of drying temperature, and most of the drying is carried out in rural sites. The collector is easy to install and can adapt to different drying volume requirements.
