How to Choose Extruded Fin Tubes and Embedded Fin Tubes

What are Extruded Fin Tubes?

Extruded fin tubes, also known as bimetallic rolled composite fin tubes, are high-efficiency heat transfer components consisting of a base tube and tightly bonded aluminum fins. The base tube is available in a variety of materials, including carbon steel, 스테인리스, or copper, to meet the needs of different operating environments and application scenarios.

What are Embedded Fin Tubes?

Embedded fin tubes are manufactured by pre-machined spiral grooves of a specific width and depth into the steel tube. Then, a steel strip is inlaid onto the tube on a lathe. During the winding process, a certain preload forces the steel strip tightly within the spiral grooves, ensuring a certain contact area between the strip and the tube.

The manufacturing process for G-type embedded fin tubes has multiple impacts on cost. Material procurement cost is a significant factor, with high-quality raw materials relatively expensive. The complexity of the processing directly determines production efficiency and labor costs.

예를 들어, the precision inlay process requires higher technical requirements and equipment investment. Depreciation and maintenance costs of production equipment are also factored into product costs.

What are the differences between extruded fin tubes and embedded fin tubes?

1. Structurally, extruded fin tubes are made of aluminum alloy and are typically formed using mechanical rolling or stretching. Embedded fin tubes, 다른 한편으로는, have multiple grooves machined directly into the surface of the steel tube, creating a fin-like structure.

2. Functionally, extruded fin tubes have a high thermal conductivity and excellent heat conduction properties, making them often used in applications requiring efficient heat transfer, such as air conditioners and radiators.

Due to their unique structure, embedded fin tubes can provide a large heat dissipation area within a smaller space, making them particularly suitable for space-constrained applications, such as computer CPU coolers.

3. Extruded fin tubes and embedded fin tubes also differ in manufacturing processes, costs, and service life.

예를 들어, extruded fin tubes have a relatively simple manufacturing process and lower costs, but a relatively short service life; embedded fin tubes, 다른 한편으로는, have a more complex manufacturing process and higher costs, but a longer service life.

Extruded fin tubes and embedded fin tubes each have their own characteristics and scope of use. When choosing, it is necessary to make comprehensive considerations based on the specific application scenario and needs.
