The finned tube is to improve the heat exchange efficiency. By adding fins on the surface of the heat exchange tube, the outer surface area (or inner surface area) of the heat exchange tube is increased, so as to achieve the purpose of improving the heat exchange efficiency. Such a heat exchange tube . Usually used for heat exchange between liquid and gas.
Finned tube is a heat exchange element. As a heat exchange element, finned tubes usually work under high-temperature flue gas conditions for a long time. For example, the finned tubes usually used in boiler or harsh environments, high temperature and high pressure, and in a corrosive atmosphere. This requires that the finned tubes should have high anti-corrosion properties, Anti-wear properties, lower contact resistance, higher Stability and anti-dusting ability.
There are many types of finned tubes, and new varieties are constantly emerging. According to the classification of processing technology, there are extruded fin tube; high frequency welded finned tubes; rolled formed finned tubes; suit formed finned tubes ; cast finned tubes; tension wound finned tubes; Inserted tubes.
According to the shape of the fins, there are square finned tubes; circular finned tubes; spiral finned tubes; longitudinal finned tubes; corrugated finned tubes; spiral serrated fins Helical Serrated Finned Tubes; pin-shaped finned tubes; integral plate-shaped finned tubes; inner finned tubes.
According to whether the fin material of the finned tube is the same as that of the base tube, it can be divided into: single metal finned tube, bimetallic composite finned tube.
Single metal finned tubes are classified by material into copper finned tubes; aluminum finned tubes; carbon steel finned tubes; stainless steel finned tubes; cast steel finned tubes.

How to choose the right DC charging solution for your business
The demand for fast and efficient electric vehicle (EV) charging solutions is growing rapidly, just like the global shift toward electric mobility. As more people switch to electric cars, businesses are looking for ways to offer EV charging at their locations—whether it's a gas station, retail store, or fleet depot. In this evolving landscape, DC fast charging has emerged as a top choice for many due to its speed and efficiency.
But with so many options available, it’s essential to understand your business needs before making a decision. DC charging isn’t one-size-fits-all, and what works for one business may not work for another. Whether you're targeting individual drivers or managing a fleet, there are several key factors to consider when choosing the right DC charging solution.
For commercial use, the first question to ask is: How long do your customers stay? If they’re passing through, like at a highway gas station, high-power DC chargers (180 kW or more) make sense. But if they're staying longer, such as at a restaurant or shopping center, a lower power output (50–90 kW) might be more cost-effective.
Another important factor is the type of EVs your customers drive. Some vehicles have larger batteries and require higher power outputs, while others can’t even benefit from ultra-fast chargers. Also, the charging connectors matter—CCS2 is now the standard in Europe, but CHAdeMO is still used in some regions, so offering multiple port options can improve accessibility.
Where you install the charging stations also matters. There are two main types of DC charging systems: standalone and split. Standalone units are compact and self-contained, while split systems allow for higher power output and greater flexibility. Depending on your space and needs, either could be suitable.
Payment methods are another consideration. Offering flexible options like RFID, apps, or contactless payments can enhance the customer experience and encourage repeat visits.
Looking ahead, the number of EVs on the road will continue to rise. That means your charging infrastructure must be scalable. Modular DC charging stations, like the EVBox Troniq Modular, let you start small and expand as demand grows.
For fleet operators, the process is slightly different. You already know your vehicles’ specifications, dwell times, and routes, which makes planning easier. However, as your fleet expands, scalability becomes even more critical. A modular approach allows you to grow your charging network without overinvesting upfront.
In conclusion, investing in modular DC charging solutions offers the best long-term value. It gives you the flexibility to adapt to future growth, meet changing EV technologies, and provide a reliable service to your customers. By offering DC charging, you not only support the transition to electric mobility but also position your business as a forward-thinking leader in the industry.
