What is A Novel Fabrication Method for Polymeric Flat Plate Pulsating Heat Pipe via Additive Manufacturing about?

Advancements in material development and fabrication techniques have led to the production of a new generation of electronic devices that are flexible, compact, small-scale, and lightweight. Effective thermal control management is crucial to ensure their performance, reliability, and durability. This paper proposes the fabrication of a polymeric pulsating heat pipe (PPHP) using a common stereolithography technology. The heat transfer performance of three PPHPs with different channel configurations was compared at heating powers ranging from 5 to 30 W and at a constant filling ratio of 50 %, using FC-72 as the working fluid due to its compatibility with the solid material. All three PPHPs have eight turns and length, width, and thickness of 185 mm, 85 mm, and 2 mm, respectively. All experiments were conducted for four thermal hysteresis cycles. The findings revealed that pressure and temperature distributions displayed similar patterns and fluctuations in response to heating power for all the PPHPs. Despite the simple technique and the use of a standard plastic material, the thermal resistance ranged from 2.5 to 1.7 • C/W, i.e., the effective thermal conductivity was already more th
