Solar Absorbers
Technical Advantages of Laser-Welded Solar Absorbers:
1. Zero Thermal Resistance: Metallurgical tube-plate fusion → 100% metal-to-metal contact.
2. Result: Thermal transfer efficiency >95%.
3. Leak-Proof Integrity: Continuous laser weld seam.
4. Result: Zero leakage over 25-year service life.
5. Extreme Corrosion Resistance: Full-sealed structure + inert-gas shielding → Passes salt spray.
6. Customization is supported according to customer requirements.
Solar Absorbers Working Principle:
The flat plate solar absorbers is a key core component that absorbs solar energy and converts it into heat energy, and transfers the heat to water.
The material, structure and surface heat absorption coating of the solar heat absorption core have a decisive influence on the performance of the water heater.
The requirements for the solar heat absorption plate are to have a certain pressure bearing capacity, good compatibility with water, and high thermal performance.

Technical Advantages of Laser-Welded Solar Absorbers:
1. Micro-Scale Melt Pool Fusion: Laser welding creates <0.5mm melt pools at absorber/riser interfaces. Extends Solar Absorbers service life beyond 25 years.
2. Seamless Architectural Integration: Zero visible weld lines → Maintains uniform surface topology. Enhanced aesthetics for building-integrated solar thermal systems.
3. Coating Integrity Preservation: Non-contact laser process prevents thermal degradation of spectrally selective coatings. Zero coating delamination at Solar Absorbers’ tube-plate joints .
4. High-Density Weld Matrix: 3mm staggered pitch welding → Achieves ≥98% conductive contact area. Solar Absorbers deliver >95% thermal transfer efficiency.
Production Line:
1. 100% Manufactory, 20+ years solar thermal industry experience
2. Leading R&D, The only company in China which can produce both blue solar coating and black solar coating.
3. Fast delivery within 2 weeks.
4. OEM & ODM orders.
Product Advantage Comparison:
Advanced technology, compared with other companies' products.
Using high frequency welding, no leakage | Too much laser point, easy to leakage | 1. The distance between two weldign spots is 3mm, more welding spots take high transmission to system. 2. Pipes and coating welded fimly have longer life span. | 1. The distance between two weldign spots is longer 10-12mm, lower transmission. 2. Pipes and coating will be dropped, working life is short. |
