best selling air temperature vaporizer in China
The action principle of this finned tube is analyzed as follows, taking liquefied petroleum gas as the working medium for example: When liquefied petroleum gas flows in the tube (vertical axial direction from bottom to top), the liquid near the inner wall of the finned tube in the cold fluid first completes the heat exchange with the outside world and vaporizes into tiny bubbles. When the tiny bubbles gather into gas, they come out and reach boiling. However, due to the short contact time between the liquid petroleum gas and the wall, the flow in the tube only convective under the action of gravity. The wall temperature of the upper and lower parts of the whole finned tube is not uniform, resulting in the finned tube heat transfer coefficient is not greatly improved, and the overall heat exchange performance of the finned tube is not fully utilized, which is the shortcoming of several domestic liquefied petroleum gas air temperature gasifier finned tube. The ATC series of our company greatly improves the heat transfer coefficient of the finned tube by using the internal suction core and spiral guide strip technology, which is 5-2.0 times higher than that of the finned tube without this technology.
