What is finned electric heating tube?

Fin type electric heating tube (heat sink electric heating tube) is made of high-quality stainless steel, high-temperature magnesium oxide powder, electric heating alloy wire, metal heat sink and other materials, and is manufactured through advanced production equipment and processes, with strict quality management. This series of products can be installed in blowing ducts or other stationary, flowing air heating occasions. Compared with ordinary components, the heat dissipation area of finned electric heating tubes has increased by 2-3 times, which means that the surface power load allowed by finned components is 3-4 times that of ordinary components. Due to the shortened length of the component, its own heat loss is greatly reduced. Under the same power conditions, it has the advantages of fast heating, uniform heating, good heat dissipation performance, high thermal efficiency, long service life, small heating device volume, and low cost. Reasonable design has been carried out according to user requirements for easy installation.

Fin type electric heating tube is composed of fins wrapped around the outer surface of the heating tube to dissipate heat.

Fin heating tubes are generally used in dry burning working environments, so what role do fins play in fin heating tubes
What about it?
The function of fins is to increase the heat dissipation area of the heating tube, that is, to increase the contact surface with the air. This can improve the heat transfer efficiency of finned electric heating tubes. Compared with heating tubes without fins, the heat transfer efficiency is greatly reduced. In practical applications, stainless steel fins are the most commonly used.
The surface temperature of the electric heating tube is an important factor affecting the service life of the heating tube in a dry burning working environment. If a finned electric heating tube is used to accelerate the heat dissipation on the surface of the heating tube, the surface temperature of the heating tube will decrease, thereby increasing the service life of the heating tube.

Used for ovens! Air conditioning equipment and drying oven heating generally use air as the heating medium.

Compared with bare pipes, it has the following advantages
 1. In limited heating devices, the power can reach 1.5 to 2 times that of the light tube, greatly reducing the size of the heating device and saving users costs. Fin type electric heating tubes are widely used in places where static flowing air is heated. Used in industries such as mechanical manufacturing, automotive, textile, food, spraying, air conditioning, etc. for hot air, ventilation, drying rooms, heating, etc.

2. The heat dissipation area of the finned electric heating tube has increased by 2.5-4 times, and the surface load of the tube has increased by 1.5-2 times. And it has the advantages of fast heating, high thermal efficiency, and long service life.
