High thermal conductivity: Due to the micro-channel structure, the Aluminum Radiator Flat Tube has a larger surface area and smaller fluid channels, enhancing its thermal conductivity and facilitating faster heat transfer.
Low fluid resistance: The micro-channel design reduces fluid resistance, minimizing pressure drop within the system and enhancing overall system efficiency.
Lightweight high strength: Aluminum material, known for its strength and hardness, combined with the micro-channel structure, results in lightweight yet durable Micro-channel tubes for heat exchangers.
High stability: Utilizing advanced manufacturing technology and materials, Micro-channel Aluminum Tubes withstand challenging environments, maintaining high stability and reliability.
Good controllability: Customizable micro-channel structure and internal design enable precise control of heat dissipation and transfer, meeting specific performance requirements.
Good corrosion resistance: Aluminum exhibits excellent corrosion resistance, ensuring prolonged use even in humid and corrosive environments.
Good security: Modular design minimizes safety issues like water leakage, ensuring user safety.
Energy saving and environmental protection: High-efficiency heat transfer properties reduce energy consumption, aligning with energy-saving and environmental protection goals.
The usage of micro-channel aluminum tubes in the automotive field
Car engine cooling system: aluminum microchannel flat tube can be used as radiators for car engines. Compared with traditional radiators, micro-channel radiators have a better heat dissipation effect and can achieve higher heat dissipation performance in the same size, thereby improving the fuel economy of the car, reducing emissions, and extending the service life of the engine.
Automobile air-conditioning system: aluminum microchannel tube can be used in evaporators and condensers in automobile air-conditioning systems. In the air-conditioning system, the high-efficiency heat transfer characteristics of the micro-channel aluminum flat tube can improve the cooling effect, so that the interior of the car can be cooled more quickly and more evenly, and the efficiency of the air-conditioning system can be improved to reduce fuel consumption and emissions.
Car transmission radiator: the car transmission generates a lot of heat during long-term operation, so a radiator is needed to dissipate the heat. The Micro-channel tubes can be used in the radiator of the automobile transmission. Through its high-efficiency heat transfer characteristics, it can improve the heat dissipation effect and ensure the normal operation of the automobile transmission.
Car turbocharger radiator: a turbocharger is a device that boosts engine output through supercharging, and generates a lot of heat when it runs inside. The Ultra Precision Micro-channel Aluminum Flat Tubes can be used in the radiator of the automobile turbocharger, and through its high-efficiency heat transfer characteristics, the temperature of the turbocharger can be reduced to ensure its normal operation.
Car seat cooling systems: some high-end cars have cooling systems on the seats to provide more comfort in hot weather. The Extra wide Parallel Flow Aluminum Flat Tube can be used in the car seat cooling system, through its high-efficiency heat transfer characteristics, it can improve the cooling effect and ensure the comfort of passengers.
In addition, the Parallel Flow Aluminium Flat Tube can also be used in automotive battery radiators, hydraulic system radiators and other fields to ensure the efficient operation and safety performance of the car.
Key items for purchasing automotive micro-channel aluminum flat tubes
