Modern LG refrigerators increasingly adopt dual-evaporator cooling systems to deliver superior food preservation, temperature stability, and energy efficiency. At the core of the fresh food compartment in this architecture is the aluminum evaporator coil, a critical heat exchange component responsible for precise cooling and humidity control.
Unlike conventional single-evaporator refrigerators, LG’s dual-evaporator system uses two independent evaporator coils:
One evaporator dedicated to the fresh food compartment
One evaporator dedicated to the freezer compartment
This separation prevents air mixing between compartments, significantly reducing odor transfer while allowing each zone to operate at its optimal temperature and humidity level.
The aluminum evaporator coil used in the fresh food section is specifically engineered for stable operation at higher temperatures compared to freezer evaporators, ensuring vegetables, fruits, and dairy products remain fresh longer.
The aluminum evaporator coil for LG refrigerator fresh food compartments typically features:
All-aluminum construction
Aluminum tubes and aluminum fins provide excellent thermal conductivity while reducing overall weight compared to copper-based designs.
Compact multi-row serpentine layout
Maximizes heat transfer surface area within limited cabinet space, supporting uniform airflow and fast temperature pull-down.
High-density louvered fins
Optimized fin spacing enhances air-side heat exchange efficiency while maintaining low frost accumulation in fresh food environments.
Integrated refrigerant distribution
Designed to work seamlessly with capillary tubes or expansion devices used in LG refrigeration platforms.
Corrosion-resistant surface
Aluminum material offers natural corrosion resistance, suitable for high-humidity fresh food compartments.
Aluminum evaporator coils deliver several performance benefits in LG dual-evaporator refrigerators:
Stable and precise temperature control
Maintains a narrow temperature band, reducing temperature fluctuations that can accelerate food spoilage.
Optimized humidity management
Supports higher relative humidity compared to freezer sections, helping keep fruits and vegetables crisp and hydrated.
Energy-efficient operation
High heat transfer efficiency reduces compressor run time, contributing to lower overall energy consumption.
Fast cooling recovery
Quickly restores target temperature after door openings, improving user experience and food safety.
These aluminum evaporator coils are commonly used in:
LG French door refrigerators
Side-by-side refrigerators
Bottom freezer refrigerators with dual-evaporator architecture
They can be supplied as:
OEM components for new refrigerator manufacturing
Replacement evaporator coils for service and aftersales markets
Custom-designed coils based on specific LG models, cooling capacity, and refrigerant type (R600a, R134a, etc.)
High-quality aluminum evaporator coils are produced using:
Precision tube forming and bending
Mechanical or expansion fin bonding
Helium leak testing for refrigerant tightness
Performance validation under simulated refrigerator operating conditions
Strict dimensional and thermal performance control ensures full compatibility with LG refrigerator airflow ducts, fan systems, and defrost strategies.
Aluminum evaporator coils play a vital role in the performance of LG dual-evaporator refrigerators, particularly in the fresh food section where temperature and humidity precision are critical. With lightweight construction, high heat transfer efficiency, and excellent corrosion resistance, aluminum evaporator coils are an ideal solution for modern energy-efficient refrigerator designs.
For OEM manufacturers and replacement part suppliers, customized aluminum evaporator coils provide a reliable, cost-effective, and performance-driven solution tailored to LG refrigerator platforms.
