What’s is finned tubular heating elements and what would happened if we add fin overall the tubular heating element?
Finned tubular electric heating element is a kind of path designed by using the principle of fluid thermodynamics to convert electric energy into heat energy. When heating the materials to be heated, the low-temperature fluid medium enters its input port under pressure through the pipeline, and takes away the high-temperature heat energy generated by the electric heating element during its operation along the specific heat exchange channel inside the electric heating container, Raise the temperature of the heated medium.
Properties of finned electric heating element: winding metal heat sink on the surface of ordinary element, the heat dissipation area is expanded by 2 ~ 3 times compared with ordinary element, that is, the allowable surface power load of finned element is 3 ~ 4 times that of ordinary element. The finned electric heating element is made of high-quality stainless steel, modified oxide powder, high resistance electric heating alloy wire, stainless steel heat sink and other materials through advanced production equipment and technology, and strict quality management is carried out. As the length of the element is shortened, the heat loss is reduced.
Compared with ordinary tubular heating element, sinton finned electric heating tubular heating element has the following advantages:
1. The heat dissipation area increased by 2.5 ~ 4 times and the pipe surface load increased by 1.5 ~ 2 times. It has the advantages of fast temperature rise, high thermal efficiency and long service life.
2. In the limited heating device, the power can reach 1.5 ~ 2 times of the light tube power, which greatly reduces the volume of the heating device and saves the cost of users. Finned electric heating elements are widely used in heating places of static flowing air. It is used for hot air, ventilation, drying room, heating, etc. in machinery manufacturing, automobile, textile, food, spraying, air conditioning and other industries
