The preparation method that an aspect of of the present present invention provides a kind of New Multi-scale aluminum flat rubber belting heat pipe, comprises the following steps:
S1 aluminum flat rubber belting heat pipe extrusion die die sinking；
Extrusion die is carried out, dries by S2；
Dried extrusion die surface is carried out electrochemical corrosion by S3；
Extrusion die surface after corrosion treatmentCorrosion Science is carried out, dries by S4;
S5 uses the extrusion die through surface roughening, disposable extruded, obtains the aluminum flat rubber belting heat pipe with multiple dimensioned microchannels.
Wherein, step S3 includes the process to extrusion die surface roughening, is specially and is energized at extrusion die two ends, and is completely immersed in caustic.Described caustic is the acid with extrusion die surface generation chemical reaction or base reagent.

The disposable extruded aluminum flat rubber belting heat pipe that obtains is carried out secondary broaching by S3, obtains the aluminum flat rubber belting heat pipe with multiple dimensioned microchannels.
Wherein, the broaching tool surface that in step S3, broaching uses has small blade.
Adopt the New Multi-scale aluminum flat rubber belting heat pipe that preparation method of the present invention is prepared from, including aluminum flat rubber belting heat pipe body, having some heat transfer paths inside described aluminum flat rubber belting heat pipe body, described heat transfer path surface configuration has groove, in described flute surfaces distribution microchannels.
Further, the internal both sides of described aluminum flat rubber belting heat pipe body are semicircular cavities.
Further, described heat transfer path is longitudinally through in described aluminum flat rubber belting heat pipe body and be parallel to each other.
Further, it is provided with reinforcement between adjacent two passages of described heat transfer path.
Further, described flute surfaces is uniformly covered with microchannels.
Compared with prior art, the method have the advantages that
Being parallel on heat pipe direction and have a plurality of separate heat transfer path in New Multi-scale aluminum flat rubber belting heat pipe of the present invention, each independent heat transfer path inherence is parallel to channel direction and is uniform-distribution with again a plurality of groove, possesses high permeability and low backflow resistance.And by extrusion die surface roughening or to extrusion secondary broaching, the flute surfaces being distributed in independent heat transfer path is made to form the microchannels group being evenly distributed, obtain continuous and sufficiently large capillary structure, this capillary structure greatly strengthen capillary attraction, significantly improves the heat transfer of aluminum flat rubber belting heat pipe, mass-transfer performance.
Technical measure is simple and easy to do, with low cost, it is simple to popularization and application.
