How Do Finned Heat Exchangers Meet Heat Exchange Requirements?

Finned Heat Exchanger: Core Heat Exchange Equipment Adapted to Customer Needs

Finned heat exchangers, with their advantages of high-efficiency heat exchange and compact structure, have become commonly used equipment in industrial heat exchange scenarios. This customer's requirements were clearly defined: a customized finned heat exchanger suitable for heat exchange between hot water and air. The parameters for both the hot water and air sides, as well as the core specifications of the heat exchanger, were clearly defined, balancing heat exchange efficiency and equipment adaptability to meet the heat exchange needs of a specific production scenario.

 

Operating Parameters: Core Operating Conditions for the Hot Water Side

The hot water side parameters of this finned heat exchanger are fixed to ensure stable heat exchange. The hot water flow rate is 3.5 t/h, the inlet temperature reaches 100℃, the outlet temperature is approximately 60℃, and the heat exchange temperature difference is 40℃, allowing for stable heat release and providing sufficient heat source for air heating. The hot water side parameter settings dictate that the heat exchanger must possess excellent heat transfer capabilities to meet the heat exchange requirements of high-temperature hot water.

 

Operating Parameters: Target Requirements for Heat Exchange on the Air Side

The air side, as the other medium in the heat exchange, has clearly defined parameters that fit the actual scenario. The air flow rate is 20,000 m³/h, the inlet temperature is based on the local annual average temperature of 18℃, and the outlet temperature is required to reach approximately 52℃, with a temperature rise of 34℃. Stable temperature rise must be achieved by absorbing the heat released from the hot water to meet the temperature requirements of subsequent air utilization.

 

Heat Exchanger Core Specifications: Material and Heat Exchange Capacity
The heat exchanger specifications are precisely matched to the operating conditions, with scientifically sound materials and heat exchange parameters. Carbon steel is used for the tubing, and aluminum is used for the fins, balancing corrosion resistance and heat exchange efficiency. The total heat exchange area reaches 164.5㎡, with a heat transfer capacity of 207kW, efficiently achieving heat exchange between hot water and air, ensuring that the temperatures of the media on both sides reach the preset target.

 

Heat Exchanger Structure: External Dimensions and Installation Fit
The finned heat exchanger has fixed external dimensions, adapting to on-site installation requirements. Measuring 1675mm × 1000mm × 1095mm (length × width × height), this compact heat exchanger occupies a small area, facilitating installation on industrial sites. Its compact design also reduces heat loss, further improving heat exchange efficiency and adapting to the customer's site space requirements.

 

Finned Heat Exchanger: Summary of Operating Condition Adaptability
The customized finned heat exchanger's parameters are precisely tailored to the customer's needs. From the operating parameters on the hot water and air sides to the specifications of materials, heat exchange area, and overall dimensions, everything is designed around high-efficiency heat exchange and stable operation. It achieves a heat transfer capacity of 207kW to meet the medium's temperature rise requirements, while its optimized material and dimensional design adapts to both on-site installation and long-term operation needs.
