The Comparison of Wound Fins and Square Fins

The finned electric heating tube expands the heat dissipation area through the fins, so as to accelerate the heat dissipation. The fins wound in the finned electric heating tube are mainly divided into steel band wound fins and square fins. Which of the two is better? Here we first distinguish the two differences from the appearance:

Through the above two pictures, we can clearly see the main difference them. In fact, we can conclude from the pictures that it must be a square fin type electric heating tube. Square fin-type electric heating tube refers to the installation of rectangular stainless steel fins (generally 25*50mm thickness 0.3-0.4mm) on the basis of U-shaped heating tube, where the distance between fins and fins is generally 5-6.5mm . The diameter of the U-shaped heating tube is generally 8-8.5mm. The square fin type electric heating tube is widely used in the air duct air heater. Because the gap between the fin and the fin is relatively large, the heat dissipation effect is much better than that of the wound fin.
