A finned electric heating tube is a type of electric energy that is converted into heat to heat a material to be heated. During operation, the low-temperature fluid medium enters its input port under the action of pressure through the pipeline, along the specific heat exchange flow path inside the electric heating vessel, and uses the path designed by the fluid thermodynamics principle to take away the high-temperature heat energy generated in the work of the electric heating element. The temperature of the heated medium is raised, and the finned electric heating tube outlet is obtained as a high temperature medium required by the process. The finned tubular electric heating element is a metal heat sink wound on the surface of an ordinary component. Compared with the common component, the heat dissipation area is expanded by 2 to 3 times, that is, the surface power load allowed by the fin component is 3 to 4 times that of the common component. . Due to the shortening of the length of the component, the heat loss of the component is reduced, and under the same power conditions, the utility model has the advantages of rapid temperature rise, high thermal efficiency, long service life, small volume of the heating device and low cost. It can be installed in a blow duct or other stationary, flowing air heating.
