Twisted Tube Heat Exchanger is to strengthen the turbulence of the flowing gas/fluid, so that the gas and the tube wall contact thoroughly. In addition to enhancing heat transfer, the twisted tube heat exchanger also has the advantages of reducing scaling, self-supporting between tube bundles, no baffle plate elements and so on.
With that being said, novel Twisted Tube Heat Exchanger is much more efficient than conventional tubular heat exchanger, or Shell And Tube Heat Exchanger. Twisted tube heat exchangers are also used in applications where the fluids are corrosive or contain particulates, as they are better able to handle these conditions than other types of shell and tube heat exchangers or Air Heat Exchanger.
Twisted tube heat exchangers are constructed from a series of twisted tubes arranged around a central tube. The tubes are twisted in such a way that the fluid will change direction multiple times as it passes through the exchanger. This increases the turbulence of the fluid and creates a larger surface area for the heat exchange, which increases the efficiency of the exchanger.
The shell is usually made from a thick metal such as carbon steel, which increases the durability of the exchanger.

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, mirroring the global shift toward electric mobility. As more people switch to EVs, businesses are increasingly looking for scalable and reliable options to offer charging at their locations. Among the many choices available, DC fast charging has emerged as a top solution due to its speed and efficiency.
DC charging, often referred to as fast or ultra-fast charging, can power up an EV in just minutes, making it ideal for customers who need a quick charge and are willing to prioritize convenience. However, with so many options on the market, it’s essential to understand your business needs before making a decision.
So, which businesses can benefit from DC charging? There are two primary use cases: commercial charging and fleet operations. Whether you're aiming to attract EV drivers to your location or manage a fleet of vehicles, DC charging offers a powerful solution that can be tailored to fit your specific requirements.
For commercial charging, consider the following key questions:
**1. How long do your customers stay at your location?**
This is one of the most critical factors. If your customers are only there for a short time, like those stopping at a highway gas station, high-power DC stations (e.g., 180 kW or more) may be necessary. On the other hand, if your customers are staying longer—such as at a restaurant or retail store—a lower power output (like 50 kW or 90 kW) could be sufficient and more cost-effective.
**2. What type of EVs do your customers drive?**
Different EVs have different battery sizes and connector types (e.g., CCS2 vs. CHAdeMO). Understanding the types of vehicles your customers use will help you choose the right charging infrastructure. For example, buses or delivery vans may require higher power outputs than passenger cars.
**3. Where can you install the charging stations?**
There are two main DC charging architectures: standalone and split systems. Standalone units are compact but may not deliver the highest power. Split systems, which separate the user interface from the power unit, can provide greater flexibility and higher power outputs.
**4. What payment methods do you prefer?**
Offering multiple payment options—like RFID cards, apps, or payment terminals—can enhance customer experience and encourage repeat visits. The ease of payment plays a big role in how customers perceive your service.
**5. What does the future hold for EV adoption?**
With electric vehicle numbers rising exponentially, your DC charging system should be able to grow with demand. Modular solutions, such as EVBox Troniq Modular, allow you to start small and expand as needed, ensuring long-term scalability.
For fleet operators, the considerations are similar but often more predictable. You’ll have better control over vehicle types, charging times, and routes, allowing you to build a more strategic and scalable charging plan.
In conclusion, while the right DC charging solution depends on various factors, investing in modular hardware is a smart move. It gives you the flexibility to adapt as the EV market evolves. By offering DC charging, you not only reduce range anxiety but also position your business as a leader in the electric mobility revolution.
