U Type Tube Solar Collector
1.Fully enclosed flow path, high toughness welding rods, fast heat transfer, corrosion-resistant, long lifespan.
2.Secondary heat exchange U-type metal flow path, high heat collection efficiency, quick heat transfer.
3.Pressurized operation, no water flow in pipes, no bursting in summer, no freezing in winter, leak-proof.
4.Customizable product size and structure for building integration.
U-Tube Solar Collector
The U-tube type utilizes vacuum tubes with internal U-shaped copper pipes to absorb solar heat and conduct it for heating and hot water applications. Heat is extracted efficiently from sunlight via the enclosed copper paths and aluminum fins.
Core Features
Operates under pressure, crafted with premium-grade materials
Modular customization available
Designed for high thermal conversion performance
Key Components
Fins: Made from 3003 anti-corrosion aluminum for fast, rust-free heat conduction
Flow Channel: Purple copper structure ensures superior conductivity and corrosion protection
