Micro LHP radiating system for integrated electrofluid power pump

Abstract

The invention discloses a micro loop heat pipe (LHP) radiating system for an integrated electrofluid power pump. The system comprises an electrohydrodynamic (EHD) evaporator, an EHD condensator, a steam pipeline, a liquid pipeline and the like. A high-voltage electrode and a porous metal sintering plate which are separated by using an insulating partition plate and are parallel to an evaporation plane are arranged in the EHD evaporator, wherein the high-voltage electrode is used for reinforcing the evaporation and the heat transfer of the evaporator; and the porous metal sintering plate can improve the reflowing speed of a liquid working medium. The evaporator has the advantages of small size, compact structure, no mechanical power and the like. A machining column with a roughened surfaceand a high-voltage electrode are arranged in the EHD condensator, wherein the machining column can accelerate the condensing speed of steam; and the high-voltage electrode improves the pumping efficiency of the liquid working medium. Therefore, the condensation and heat exchange efficiency of the micro LHP is greatly improved. The radiating system can fully and immediately cool electronic components and parts with high-heat flux density, thereby meeting radiating requirements on high-performance micro electronic components and parts.
