Characterization of polypropylene pulsating heat stripes: Effects of orientation, heat transfer fluid, and loop geometry

A parametric analysis of the thermal performance flat polypropylene pulsating heat pipes (PHPs) is presented. In particular, was characterized for with different number turns serpentine channel, orientations respect to gravity, and containing transfer fluids. The dependence polymeric PHPs on design parameters poorly understood date. development by high mechanical flexibility will have significant impact management smartphones, portable electronics, deployable systems such as cube satellites. Several prototype channel were fabricated bonding together three sheets selective transmission laser welding, after cutting out a in central sheet. devices supplying an ascending/descending stepped power ramp evaporator, measuring corresponding equivalent resistance between evaporator condenser.
