Stainless steel heating element

Advantages of stainless steel finned electric heating tubes:

Compared with ordinary heating tubes, the finned tubular heating tube has the following advantages, the heat dissipation area of the finned tubular heating tube is increased by 2.5~4 times compared with the ordinary light pipe, and the surface load is increased by 2~3 times compared with the light pipe, and the heat loss of the heat sink electric heating device is reduced due to the shortening of the length of the heat sink electric heating device. Under the same power conditions as the fluorescent tube, it has the advantages of fast heating, high thermal efficiency and long service life. In the limited heating device, it can accommodate the total power of 2~3 times the capacity of the superluminous tube, which greatly reduces the volume of the heating device and saves the user's cost
