III. Groundbreaking Core Technologies — Establishing Industry Leadership

The excellent performance of the EFPC High-Efficiency Integrated Large Flat-Plate Collector stems from the groundbreaking innovations of three core technologies:

1. Selective Absorption Coating Technology — Thermal Efficiency Reaching 0.813

Shengtuoke is the world's only manufacturer that produces both "blue film" and "black film" — core materials for solar thermal applications. It has always regarded material innovation as the foundation of product research and development. The company is not only a developer and manufacturer of flat-plate solar products but also masters the production technology of core materials, ensuring controllable product quality and optimal performance from the source.

The selective absorption coating used in the EFPC High-Efficiency Integrated Large Flat-Plate Collector is the result of years of research and optimization. This special coating can maximize the absorption of solar radiation while suppressing heat radiation loss, realizing efficient photothermal conversion. Strictly tested by a national-level laboratory in China, the product's thermal efficiency reaches an industry-leading level of 0.813, ensuring that the product maintains excellent heat collection performance under various environmental conditions.

2. Finite Element Method-Based Full Flow Channel Design Optimization — Powerful and Stable Thermal Output

The EFPC High-Efficiency Integrated Large Flat-Plate Collector adopts an advanced finite element analysis method. Through a large number of simulation calculations and experimental verifications, it selects the optimal heat transfer factor layout scheme and fully optimizes the flow channel design. This scientific R&D method ensures more uniform heat distribution inside the collector and significantly improves heat transfer efficiency.

The optimized flow channel design enables the collector to maintain powerful and stable thermal output even under harsh working conditions with large temperature differences, avoiding the problem of performance degradation of traditional collectors under extreme conditions. This innovative design scheme has won the Shandong Provincial Science and Technology Progress Award, reflecting its groundbreaking contribution in the technical field.

3. Innovative Heat Insulation Chamber Technology — Low Heat Loss and Better Adaptability to Large Temperature Differences

The EFPC High-Efficiency Integrated Large Flat-Plate Collector innovatively applies the "heat insulation chamber" technology. Through integrated overall design, it fully optimizes the thermal insulation performance of the product. This technology effectively reduces the heat loss of the collector during operation and standby, resulting in a product heat loss coefficient of only 2.2, which is much lower than the industry average.

The heat insulation chamber technology enables the product to maintain excellent performance under harsh climate conditions. Whether in the cold northern winters or continental climate areas with large day-night temperature differences, it can ensure the efficient and stable operation of the heat collection system, greatly expanding the applicable geographical scope of the product.
