How the Aluminium Pipe Coil Works

The working principle of the Lynxcool Aluminium Pipe Coil is based on natural air circulation and efficient heat absorption.

Natural Convection Cooling Without Fans

The vertical fin channels guide air movement naturally. Cold air produced around the coil descends into the storage area, while warmer air rises toward the coil surface for continuous cooling.

Because no fan motor is required, the system reduces electricity consumption and avoids additional heat generated by fan operation.

High Humidity Preservation for Sensitive Products

Traditional fan evaporators may increase air movement and accelerate moisture loss from stored products. The low air velocity of the aluminium pipe coil helps reduce dehydration, making it suitable for fruits, vegetables, seafood, and fresh food storage.

Stable Temperature Distribution Inside Cold Rooms

The aluminium body provides good thermal conductivity and cold storage capability. This helps reduce frequent temperature changes caused by compressor cycling and improves temperature stability during daily operation.

Where Aluminium Pipe Coil Is Used

The Lynxcool Aluminium Pipe Coil is mainly applied in cold rooms where product quality depends on stable temperature and humidity conditions.

Fresh Food and Agricultural Storage

Used for fruits, vegetables, flowers, and agricultural products requiring high humidity preservation. The gentle natural airflow helps reduce moisture loss and maintain product appearance during storage.

Seafood and Meat Cold Storage

Suitable for seafood warehouses, meat storage rooms, and frozen food facilities. The fanless structure reduces airflow speed, helping minimize surface drying during storage.

Pharmaceutical and Biological Storage

The system can be applied in temperature-controlled rooms for pharmaceuticals and biological materials where stable temperature conditions and clean operating environments are required.

Commercial and Industrial Cold Rooms

For warehouses and processing facilities requiring low-noise refrigeration equipment, the aluminium pipe coil provides a simple structure with fewer moving components and reduced maintenance requirements.

Why Choose a Fanless Aluminium Coil Design

Cold storage operators often face problems such as product weight loss, uneven temperature, energy consumption, and maintenance caused by traditional air coolers. The aluminium pipe coil design addresses these issues through a simpler cooling structure.

Lower Operating Energy Consumption

Without fan motors running continuously, the system reduces electrical consumption and removes fan-related maintenance costs.

Reduced Product Moisture Loss

The gentle airflow environment helps maintain product humidity, which is important for fresh produce, seafood, and other moisture-sensitive goods.

Simplified Maintenance Requirements

Fewer mechanical components mean fewer potential failure points. Routine inspection mainly focuses on coil cleanliness, refrigerant condition, and defrost performance.

Engineering Design Details

The Lynxcool Aluminium Pipe Coil is developed with a focus on heat transfer efficiency, corrosion resistance, and stable operation in cold storage environments. The design combines aluminium alloy material, special fin geometry, and optimized refrigerant channels to achieve reliable performance without forced airflow.

Outer Fin and Inner Thread Tube Structure

The coil adopts an outer-fin and inner-thread tube design. The external fins increase the contact area with surrounding air, improving natural convection heat exchange, while the internal threaded surface improves refrigerant flow and reduces resistance inside the tube.

This structure helps achieve efficient heat transfer with a lower refrigerant charge compared with conventional smooth tube designs.

Aluminium Alloy Construction for Better Thermal Response

Aluminium alloy provides excellent thermal conductivity while keeping the overall coil weight lower than traditional steel tube structures.

The lightweight construction simplifies installation and reduces the load on cold room supporting structures. The aluminium surface can also be treated with special coatings to improve corrosion resistance in humid environments.

Natural Air Circulation Design

The vertical fin arrangement creates a continuous air circulation path inside the cold room. Cold air naturally moves downward from the coil surface, while warmer air rises to complete the circulation process.

This airflow pattern avoids strong direct air blowing, which is beneficial for products requiring controlled humidity and reduced surface drying.

Compatible with Multiple Refrigeration Systems

The Lynxcool Aluminium Pipe Coil can be configured for different refrigeration systems, including common HFC refrigerants and ammonia refrigeration applications.

For industrial refrigeration projects using R717 ammonia systems, aluminium construction helps avoid copper-ammonia compatibility issues and provides a suitable material solution for long-term operation.

Integrated Electric Defrost Structure

For applications operating below freezing temperature, frost accumulation management is essential. The coil can be equipped with electric heating elements and drip trays to support efficient defrosting.

The defrost system helps maintain heat transfer performance and reduces operational interruptions caused by excessive frost formation.

Technical Parameters

Installation and Selection Considerations

Proper selection and installation directly affect cooling performance. Lynxcool recommends evaluating cold room size, product load, operating temperature, and refrigeration system before selecting the coil model.

Cold Room Layout

The coil should be installed with sufficient ceiling clearance to allow natural air circulation. A recommended clearance of 150–200 mm helps maintain the chimney effect and improves airflow movement.

Selecting Tube Diameter and Fin Configuration

Smaller diameter coils are suitable for medium cooling requirements, while larger diameter tubes and additional fin surfaces are recommended for larger cold rooms with higher heat loads.

Refrigerant Distribution Planning

For longer tube layouts exceeding recommended single-pass lengths, parallel circuits and proper refrigerant distribution methods should be considered to maintain balanced cooling performance.

Defrost Management

Defrost frequency depends on operating temperature, humidity level, and frost accumulation. Regular monitoring helps maintain heat transfer efficiency and reduces unnecessary energy consumption.

Manufacturing and Quality Control

Lynxcool controls the manufacturing process of aluminium pipe coils from material selection to final inspection. Each unit is produced according to defined production procedures to ensure consistency between different batches.

Material Inspection

Aluminium alloy materials are checked before production to confirm dimensional accuracy and suitability for refrigeration applications.

Production Process Control

The manufacturing process includes tube forming, fin pressing, assembly, connection processing, and surface treatment. Production control helps maintain stable heat transfer performance and structural quality.

Factory Testing Before Delivery

Each coil undergoes pressure and leakage testing before shipment. Inspection records help customers confirm product quality and installation readiness.
