In high-temperature thermal oil heating and cooling systems, laser-welded finned tube heat exchangers are a superior high-end solution: They solve the pain points of traditional finned tubes, such as high-temperature weld detachment, vibration failure, heat transfer attenuation, and pipe deformation and leakage, offering superior heat transfer efficiency, stability, and service life. They are suitable for industrial production lines and large thermal oil furnace systems with high requirements for continuous operation, energy saving, and low failure rates. For medium-temperature (<280℃) conventional operating conditions with limited budgets, high-frequency welding can be used as an alternative.
