BTE Solar: Professional Manufacturer And Exporter of Semi-Finished Solar Heat Absorbing Fins

Product Introduction: The core heat-conducting component of the solar thermal system

As a professional manufacturer deeply engaged in the thermal energy field for many years, we are dedicated to providing high-performance solar heat-absorbing fin semi-finished products for global solar collector brands and assembly plants. This product is the core component of solar vacuum tubes or flat plate collectors, directly responsible for absorbing solar energy and efficiently transferring it to the internal copper or aluminum heat pipes. It is the key to determining the efficiency of the entire solar thermal system.

Our semi-finished heat-absorbing fins are made of high-quality 1070/1060 aluminum alloy or TU1 oxygen-free copper strips, and are manufactured through precision rolling, high-speed stamping and advanced surface treatment processes (such as selective absorption coating anodizing). The products are exported in the form of coil or fixed-length sheet materials, providing customers with great production flexibility in subsequent cutting, bending, welding with heat pipes and overall assembly. This OEM/ODM cooperation model enables you to respond quickly to the diverse demands of the market, optimize the efficiency of your own supply chain, and focus on the development of brand and terminal markets.

Core product advantage: Why choose our heat-absorbing fins?

Outstanding heat conduction efficiency and stability

High thermal conductivity materials (aluminum alloy/copper) are carefully selected to ensure that heat can be rapidly and evenly transferred from the fin surface to the flow channel. Through strict process control, we ensure the stability of the material's crystal phase structure, thus maintaining excellent energy conversion efficiency even in long-term high-temperature working environments and directly increasing the heat gain of the entire solar water heating system.

Excellent surface treatment and high absorption ratio

For aluminum fins, we offer advanced selective absorption coating anodizing treatment. This coating features a high solar energy absorption rate (α≥0.93) and a low infrared emissivity (ε≤0.12), maximizing the capture and retention of solar energy and reducing thermal radiation loss. It serves as a technical guarantee for achieving high efficiency in collectors.

Precise geometric dimensions and consistency

High-precision molds and automated stamping production lines are adopted to ensure that the thickness, fin spacing and flatness of each fin all comply with strict design tolerances. The consistency of this batch production ensures that your automated welding and assembly lines can operate smoothly, significantly reducing the defect rate of production and improving the qualification rate of the final products.

Strong customized design and adaptation capabilities

We possess strong mold development capabilities and rapid prototyping experience. Whether it is vacuum tube collectors of different pipe diameters or flat-plate collectors of various specifications, we can provide the most suitable fin shape, size and thickness solutions based on your heat pipe structure and fluid dynamics requirements, achieving seamless integration and the best thermal performance matching.

Significant cost-effectiveness and supply chain optimization

By purchasing our semi-finished products, you don't need to invest in expensive precision rolling mills, stamping equipment and anodizing production lines. This greatly reduces your investment in fixed assets and unit production costs. Meanwhile, our stable supply capacity and efficient logistics response can help you reduce raw material inventory and achieve lean production.

Success cases and applications

Our semi-finished solar heat-absorbing fins have been widely applied in solar hot water projects in many countries and regions around the world, and we have established stable cooperative partnerships with numerous well-known brands.

Case One: Cooperation with a well-known European collector brand

A Latin America region is seeking an aluminum fin with high absorption rate and long service life for its new generation of high-efficiency flat-plate collectors. In accordance with its strict EN12975 standard, we have developed fins with a specific alloy formula and adopted our unique blue titanium coated anodizing process. Over the past three years of cooperation, our products, with their outstanding stability and consistency, have helped this client successfully upgrade the energy efficiency grade of its products and consolidate its position in the high-end market.

Case Two: Development of Emerging Markets in Southeast Asia

A Vietnamese start-up company hopes to quickly enter the household solar energy market with a more cost-effective solution. We recommended an economical and efficient standardized fin semi-finished product solution for it and provided detailed technical guidance, enabling it to flexibly assemble using local labor. This cooperation has significantly lowered the customer's start-up threshold and production costs, enabling their products to rapidly gain market share in a short period of time.

These successful cases fully demonstrate the reliability of our products, the adaptability of our technologies and the flexibility of our services as international suppliers. No matter where you are or what technical challenges you face, we have the confidence and ability to become your most reliable partner for "Made in China".
