Many people choose B-Tubes for Folded Radiator, which is characterized by high strength, good heat dissipation, lightweight, long service life, and excellent cost, especially suitable for automotive/construction machinery water tanks and compact heat exchange scenarios.
1、 Strong structure and high pressure resistance (core)
Seamless folding structure: The aluminum plate is rolled and folded into a "B" shape without side welds, avoiding the risk of cracking in traditional flat pipe welds.
Double layer bridging: The folded part is internally brazed to form a strong connecting bridge, with blast resistance 30% -50% higher than ordinary pipes, high pressure resistance, and vibration resistance.
Good structural rigidity: The overall rigidity is high, and it is not easy to expand or deform, suitable for high temperature/high pressure/heavy earthquake conditions (such as trucks and construction machinery).
2、 Higher heat dissipation efficiency
Larger heat exchange area: The B-shaped section has 15% -25% more heat dissipation area than the same width flat tube, providing stronger heat dissipation in a compact space.
Turbulence enhancement: The middle folding edge disturbs the coolant, reduces laminar flow, improves heat transfer coefficient, cools down faster, and reduces thermal resistance.
Fin contact is more stable: the folded side has a larger brazing area, the fins are firmly attached, not easily detached, and long-term heat dissipation is stable.
3、 Lightweight, compact, and highly adaptable
Thinner and lighter: thinner aluminum material (0.25-0.35 mm) can be used, reducing weight by 10% -20% with the same heat dissipation capacity, in line with the trend of lightweighting.
High space utilization: More space saving in the thickness direction, suitable for compact passenger cars and new energy vehicles with engine compartments.
Compatible with automation: suitable for high-speed rolling and brazing mass production, with good consistency and high yield rate.
4、 Long lifespan and good reliability
Stronger corrosion resistance: no weld seam reduces the weak points of corrosion; Folding the inner side forms a "protective layer", which is more resistant to coolant corrosion/scaling.
Excellent fatigue resistance: stress distribution is uniform, cold and hot cycles are not easy to crack, and the service life is 20% -40% longer than ordinary flat pipes.
Low maintenance cost: not easy to leak or block, low failure rate, and minimal downtime.
5、 Good economy
Low material cost: thin material+high efficiency, using fewer materials with the same properties and lower costs.
High production efficiency: one-time molding, eliminating the welding process, faster production, and less labor.
