A Review of MHP Technology and Its Research Status in Cooling of Li-Ion Power Battery and PEMFC
A lithium-ion (Li-ion) power battery and proton exchange membrane fuel cell (PEMFC) have an excellent electrical conversion performance, which makes them a hot spot in the new energy power research field. Electricity is generated inside the battery through an electrochemical reaction, during which time a large amount of heat is also generated. The ideal operating temperature of a Li-ion battery and PEMFC falls into a small range, but the operations require a high temperature uniformity. Efficient cooling technology can be used to timely discharge the heat generated and control the temperature field change inside the battery, thus ensuring the battery's efficient and stable performance. The micro heat pipe (MHP) is currently a more efficient passive cooling equipment with high heat fluxes and a high thermal conductivity through the phase change heat transfer of working fluid. The development and research status of an MHP and its application in the cooling of a Li-ion power battery and PEMFC are reviewed in this paper.
