specific implementation method
Below in conjunction with accompanying drawing, enforcement of the present utility model is further described:
The hollow sealing case material of micro heat pipe is copper or other high-thermal conductive metal.
Heat transfer medium in the hollow sealing housing of micro heat pipe is the water-based nano-fluid containing the nano particle such as metal and metal oxide.
The method such as chemical bath deposition, magnetron sputtering is adopted to construct nano array structure 6 at inside pipe wall after clearing up the inner surface of micro heat pipe seal casinghousing 4.For reducing thermal resistance, this nanostructured is based on high-thermal conductive metal and metal oxide, and nanostructure diameter is 10 ~ 50nm, is highly 50 ~ 200nm.
Pour into suitable nano fluid heat transferring medium after being vacuumized by micro heat pipe seal casinghousing, then close the mouth of pipe, form enclosure space.
When the seal casinghousing endotherm section 1 of micro heat pipe is heated, the nano fluid heat transferring medium rapid vaporization in seal casinghousing, steam flows to heat release section 3 under small pressure differential, in heat release section condensation, and releases heat, by capillarity, heat transfer medium is back to evaporator section 3.By this Rapid Circulation, heat can be come by conduction continuously.
The utility model by constructing nano array structure 6 in heat pipe, effectively increase structural table area, facilitate the heat flux transfer rate of evaporator section, construct nano array structure 6 and also add capillary pressure, facilitate heat transfer medium circulation, benefit heat transfer medium and reflux to evaporator section.In seal casinghousing, add heat transfer medium nano-fluid 5, add the capacity of heat transmission of heat transfer medium, more improve the heat transfer efficiency of micro heat pipe.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model is also not limited only to above-mentioned citing, and the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or alternative, also belong to protection domain of the present utility model.
