지느러미 붙은 튜브: Manufacturing, Functions and Advantages

Introduction to Finned Tubes

Finned tubes are essential heat transfer components widely used in various industrial applications. These specialized tubes feature extended surfaces (fins) that significantly improve thermal efficiency in heat exchangers, air coolers, and other thermal systems.

Finned tubes are used to enhance heat transfer by adding fins to ordinary base tubes.

The base tubes of finned tubes can be steel tubes; stainless steel tubes; copper tubes, 등. The fins can also be steel strips; stainless steel strips, copper strips, aluminum strips, 등. Any heat exchanger that adds fins to the heat exchange tubes to increase the heat dissipation area.

The common finned tubes in our lives are divided into square finned tubes, spiral finned tubes, 세로 지느러미 붙은 관, spiral serrated finned tubes, and inner finned tubes. You can choose according to actual needs.

The material of the finned tube will also affect the heat transfer effect of the finned tube. From the classification of finned tube materials, there are single metal finned tubes and bimetallic composite finned tubes.

핀 튜브 Manufacturing Processes

1. Extruded Fins:
   • Aluminum fins are extruded directly from the tube material
   • Creates seamless, high-strength fin-tube bond
   • Most common for aluminum tubes
2. Embedded Fins:
   • Grooves are machined into the base tube
   • Fins are inserted and mechanically locked
   • Suitable for high-temperature applications
3. Wrapped Fins:
   • Metal strips are helically wound around the tube
   • Bonded through tension or adhesive
   • Cost-effective for large-scale production
4. Welded Fins:
   • Individual fins are welded to the base tube
   • Provides excellent thermal contact
   • Used in corrosive environments

핀 튜브 Key Functions

1. Enhanced Heat Transfer:
   • Increases surface area by 5-10 times compared to bare tubes
   • Improves convection heat transfer efficiency
2. Space Optimization:
