The heat exchanger frame of flat tube composition and some fins being arranged in heat exchanger frame, its
In：Header is provided with the conduit for inserting flat tube, and multiple microchannels are contained in flat tube inside
Structure.
Gap between described fin and header is provided with anticorrosive, the anticorrosion material
Material is preferably sponge or plastics, and to prevent fin from being contacted with header, the electrochemistry to be formed is rotten
Erosion.
Described fin is formed by surface treated aluminum foil rolling, and fin width is than between flat tube
Can be that shutter form can also be other high-efficiency fin forms away from big 0.01-0.03mm.
Described surface treatment is applied using various existing surface treatment widely used in air conditioner industry
Cover coating realization.
Compared with existing micro-channel heat exchanger manufacture, the invention has the advantages that：Cold extrusion work
Skill can connect header and flat tube, complete the shaping of micro-channel heat exchanger framework, it is to avoid
The high energy consumption of soldering, eliminates the large scale equipments such as soldering oven, improves production efficiency and reduces
Cost.Fin and flat tube are connected rather than welding using viscose material so that fin is entered
Row surface treatment has may.Fin raw material can use hydrophilic (or hydrophobic) as needed
Aluminium foil, improves heat exchanger draining, frosting, anti-corrosion and Soot Performance.
