Stainless steel low thread fin tube for heat exchanger

Internally threaded fin tube

1. Working principle of stainless steel low thread fin tube

Stainless steel low-thread fin tube is a heat transfer device. Its working principle is to transfer heat through convection heat transfer between the tube wall and the fins.

The stainless steel low-thread fin tube has a lower fin height, a larger surface area, and a smaller pitch, which results in increased turbulence when the gas flows through the fins, thereby increasing the heat transfer coefficient.

2. Structural form of stainless steel low thread fin tube

The structural form of stainless steel low-thread finned tubes generally includes an inner and an outer two-layer tube shell, and the middle layer is covered with evenly distributed fins. The height of the fins is low and the pitch is small, usually 2.5~5mm, which is 1/3~1/2 smaller than ordinary fin tubes. The fins are generally sail-shaped, sheet-shaped or crown-shaped, and their materials are generally aluminum alloy. , copper alloy, carbon steel and stainless steel, etc.

3. Advantages and characteristics of stainless steel low-thread finned tubes

Compared with traditional fin tubes, stainless steel low-thread fin tubes have the following advantages:

A.Better heat transfer performance.

Due to its low fin height and small pitch, it can increase the turbulence of the heat exchange channel and improve the heat transfer coefficient, thereby achieving better heat transfer effects.

B.Lower aerodynamic noise.

The stainless steel low-thread fin tube has a lower fin height and a smaller pitch, which reduces the friction of the airflow on the fins and reduces the generation of noise.

C.Higher strength and stability.

The stainless steel low-thread fin tube has a tighter fin design and a stronger structure, thereby increasing its load-bearing capacity and operational stability.

D.Save more space.

Stainless steel low thread finned tubes have lower fin height and smaller pitch, which can reduce the size of the heat exchanger and save space.

To sum up, the stainless steel low-thread fin tube is a new type of pressurized heat transfer device. Its fin height is lower, the pitch is smaller, it has better heat transfer efficiency and lower aerodynamic noise, and it is widely used in Various industrial fields have broad development prospects.
