What is the heat transfer principle of laser welding stainless steel finned tube
For many users of finned tube, the heat transfer principle is unfamiliar to the machine. Next, we will follow the manufacturer of laser welded stainless steel finned tube Murphy to have a detailed understanding.
Laser welded stainless steel finned tube manufacturer Murphy said: to understand the heat transfer principle of finned tube, first to understand what is the heat transfer coefficient. Heat transfer coefficient refers to the heat transfer capacity per unit temperature difference and per unit heat exchange area, which can reflect the heat transfer capacity between the fluid and the wall.
Finned tube is a heat exchanger composed of round tube or smooth tube, so how to improve the heat transfer of round tube? One of the effective methods is to use the extended surface on the outer surface of the tube, that is, the flue gas side, to make the finned tube. It is assumed that the actual heat transfer area of finned tube is several times of the original outer surface area of smooth tube. Although the heat transfer coefficient of flue gas is still very low, the heat transfer effect reflected on the outer surface area of smooth tube will be greatly increased, so that the whole heat transfer process will be enhanced. When the total heat transfer is appropriate, the metal consumption of the equipment will be reduced and the economy will be improved.
