Micro-channel aluminum flat tube, also known as "parallel flow aluminum flat tube", is a thin-wall porous flat tubular high efficiency heat exchanger material, with excellent thermal conductivity and good corrosion resistance, mainly used in a variety of automotive, air conditioning, refrigerator and other systems. It is a pipeline component carrying a new type of environmentally friendly refrigerant, and it is also a new type of efficient heat exchanger material.
I. Structure and characteristics of micro-channel aluminum flat tube
The inside of the aluminum flat tube is composed of a plurality of tiny channels, which are rectangular, triangular, circular and other forms, and the width of the channel is usually less than 0.5mm. After special treatment, the inside of the micro-channel aluminum flat tube can form a uniform aluminum oxide protective layer to improve the corrosion resistance. At the same time, the wall thickness of the micro-channel aluminum flat tube is generally less than 0.2mm, and the heat conduction performance is high.
Second, the application field of micro-channel aluminum flat tube
1. Automotive sector
Microchannel aluminum flat tubes are widely used in evaporators and condensers in automotive air conditioning systems. Compared with traditional copper and aluminum tubes, the micro-channel aluminum flat tube has better heat conduction performance, can achieve faster cooling effect, and can reduce the weight and space of the system.
2. Air conditioning field
Micro-channel aluminum flat tube is also widely used in the evaporator and condenser of air conditioning system. Compared with traditional copper tube and aluminum tube, micro-channel aluminum flat tube can improve the heat exchange efficiency of the system and reduce the energy consumption and operating cost of the system.
3.Refrigerator field The micro-channel aluminum flat tube is used in the condenser and evaporator in the refrigerator, which can improve the refrigeration effect, reduce energy consumption and noise, and reduce the volume and weight of the refrigerator compared with the traditional copper tube and aluminum tube.
4. Electronic equipment field
Micro channel aluminum flat tube is also used in electronic equipment radiator, compared with the traditional copper tube, aluminum tube, micro channel aluminum flat tube can improve the heat dissipation efficiency, reduce the temperature rise of the equipment, thus extending the service life of the equipment.
