The iterative upgrading of modern thermal management equipment sets higher requirements for the structural design, heat transfer efficiency and compatibility of heat exchange tubes. Traditional round tubes and ordinary flat tubes feature simple structures with limited heat exchange areas, making them unsuitable for manufacturing new lightweight and compact heat exchangers. As a new-generation core thermal management tube, microchannel extruded flat tubes are formed by integrated hot extrusion. These thin-walled multi-port heat exchange components are widely used in home appliance refrigeration, vehicle temperature control, industrial heat dissipation and other applications. Our company specializes in the R&D and mass production of microchannel extruded flat tubes. With mature extrusion, surface protection and precision machining technologies, we supply tubes in multiple specifications and support non-standard customization to meet supporting production demands for various heat exchange equipment.
Microchannel extruded flat tubes are manufactured from refined aluminum rods via integrated hot extrusion. The forming process eliminates joining and welding steps, delivering continuous tube bodies without assembly gaps. Multiple evenly distributed micro flow channels are arranged inside the tube. This multi-port structure expands the flow space for media and increases the contact area between tubes and working fluids to improve heat transfer efficiency for circulating heat exchange with refrigerants and coolants. The wall thickness can be uniformly controlled. The lightweight profile fits the industry trend toward smaller and lighter heat exchange equipment.
The physical properties of these components support long-term continuous thermal cycling. Extruded tube bodies maintain stable structural strength and withstand normal pressure fluctuations during operation, resisting deformation, bulging and cracking. Tubes undergo professional zinc spray anti-corrosion treatment to form a protective outer layer. This layer mitigates damage from humid environments and medium corrosion, slowing oxidation and aging for long-term service in demanding working conditions such as outdoor units, vehicle systems and high-humidity workshops. The tubes also have excellent bending performance and can be shaped to match pipeline layouts for complex routing assembly.
In terms of manufacturing, our standardized extrusion lines produce microchannel flat tubes in various dimensions. Tube width, thickness and internal port quantity can be adjusted according to equipment requirements, covering specifications for common consumer devices and large industrial heat exchangers. Production strictly controls extrusion temperature, forming speed and cooling cycles to guarantee consistent wall thickness and regular channel geometry. Tube defects are minimized to ensure uniform quality across batches for streamlined assembly by equipment manufacturers.
Microchannel extruded flat tubes serve a broad range of applications. For household appliances, they act as evaporator and condenser components in air conditioners, refrigerators, freezers and dishwashers, reducing internal pipeline footprint and optimizing overall equipment structure. In automotive thermal management, they are used in air conditioning and battery cooling circuits for passenger cars and new energy vehicles. Their lightweight characteristic cuts total equipment weight to satisfy automotive operating requirements. For industrial use, they are adopted in industrial cooling units, data center cooling systems and compact temperature control equipment.
Compared with conventional heat exchange tubes, microchannel extruded flat tubes offer superior space utilization. Their multi-channel structure achieves efficient heat transfer within confined spaces and helps reduce overall equipment size. Lower tube weight reduces raw material consumption, supporting the industry shift toward lightweight equipment. The sealed multi-port design stabilizes medium flow rates for smooth heat transfer during prolonged non-stop operation.
Our company provides bulk supply of standard microchannel extruded flat tubes and accepts custom orders based on customer drawings or samples. Tube specifications and forming processes can be adjusted to match equipment structures, heat transfer parameters and assembly requirements. All finished products pass multi-stage inspection before shipment, covering visual checks, dimensional verification, pressure resistance and anti-corrosion performance testing to screen qualified tubes. Backed by a robust production system, we efficiently deliver prototypes, small trial batches and large-volume orders, providing reliable tube supply for heat exchange equipment manufacturers.
