Design, fabrication and testing of mini flexible heat pipe

Prototypes of flexible heat pipes have been designed and fabricated to provide extra freedoms in bending, twisting, oscillating and deforming to overcome the constraints in the compact electronics with awkward space layout. Visualizations of the two-phase flow patterns inside the heat pipe together...
