Welded B-Type Tubes for Radiators are used for radiators. Their core function is to maximize the heat dissipation area in a limited space, improve structural strength and pressure resistance, evenly distribute heat medium, and reduce leakage risks. They are the core components of industrial radiators and automotive cooling systems.
1、 Core structure
Section B: A metal sheet is rolled and folded into a "B" - shaped section, with a welded reinforced partition in the middle to form a double cavity flow path.
Welding Forming: High frequency welding or brazing is used, with high joint strength and good sealing.
Double row layout: The B-type light pipe is a double row steel pipe connected in parallel, with welded boxes at both ends to form a winding flow channel.
2、 Five core roles
1. Efficient heat dissipation (core)
Heat dissipation area increased by 50% or more: Within the same space, the heat dissipation area of a double row (Type A) is increased by more than 50% compared to a single row (Type A), and the heat exchange efficiency is improved by 25% or more.
Uniform heat distribution: Double chamber/double row flow paths make the distribution of heat medium (water/steam) more uniform, and the spatial temperature difference is controlled within * * ± 1.5 ℃ * * (Type A ± 3 ℃).
Convection enhancement: B-shaped cross-section/double row structure optimizes air convection, resulting in fast heating and stable heat dissipation.
2. High strength and high pressure resistance
Internally reinforced partition: The welded partition in the middle forms a "reinforced beam", which increases deformation resistance and explosive pressure resistance by more than 30%.
Pressure bearing 1.0-1.6MPa: far exceeding Type A (1.0MPa), suitable for high-pressure conditions such as steam (0.8-1.0MPa) and high-temperature hot water.
Thin material high strength: With high structural strength, thinner materials can be used, reducing weight by 20% -30%, lowering costs and saving energy.
3. Flow path optimization and low resistance conveying
Dual chamber parallel connection: Short and smooth flow path, low medium flow resistance, high cycle efficiency, and low energy consumption.
Diagonal flow in the header: The inlet/outlet of the upper and lower headers are distributed diagonally, forcing the heat medium to be evenly divided and avoiding local overheating/undercooling.
4. Reliable sealing, leak prevention, and long lifespan
Fully welded structure: The joints between the pipes and the header, as well as the pipe body, are all welded, with zero leakage risk and suitable for high-pressure/high-temperature media.
Hard brazing/high-frequency welding: The weld seam has high strength, temperature and corrosion resistance, and the service life is extended by more than 40% compared to ordinary welded pipes.
Anti vibration/anti impact: The overall rigidity is good, and it has strong anti vibration and anti impact capabilities in automotive/industrial scenarios.
5. Wide adaptability, easy installation and maintenance
Multi scenario adaptation: automotive radiators, industrial light pipes, greenhouse/workshop heating, engineering machinery cooling.
Flexible customization: pipe diameter (57-108mm), wall thickness (3.5-5mm), length can be customized, both wall mounted and floor mounted.
Easy maintenance: The smooth surface is not prone to dust and scaling, easy to clean, and has low maintenance costs in the later stage.
3、 Typical applications
Car cooling: radiator tank, intercooler, oil cooler, suitable for high pressure and vibration conditions.
Industrial heating: workshops, warehouses, greenhouses, steam/hot water systems, efficient heating for large spaces.
Construction machinery: Excavators, loaders, radiators, resistant to vibration and high pressure.
