“…To further enhance the heat transfer performance of the heat pipe, researchers have optimally enhanced the heat pipe through different optimization methods. As shown in Figure 20 a [ 93 ], Li used helical coils to flexibly match different heat pipe shells and found that the local lateral temperature difference in the heat pipe may be optimized under zero gravity. Jafari et al [ 94 ] developed a mathematical model using the genetic algorithm II optimization method to optimize the structural parameters of the sieve wick with the design parameters as decision variables.…”

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.

As an efficient heat exchange component, the gravity heat pipe can effectively control the accumulated temperature inside gangue dumps and enable reuse of transferred heat. This study establishes a similar simulation experimental platform for gravity heat pipes to control gangue dumps and thermoelectric generation. The influence of wind speed on the start-up performance and isothermal performance of gravity heat pipes is analyzed, along with the impact of wind speed on their thermoelectric generation performance. Initially, the optimal working fluid height and heating height are determined, followed by a comparison and analysis of the isothermal performance, start-up performance, and thermoelectric generation performance of the gravity heat pipe under different wind speeds. The results indicate that at a wind speed of 1.0 m/s, the gravity heat pipe exhibits better start-up and isothermal performance. At a wind speed of 2.0 m/s, the thermoelectric power generation reaches its peak. In the range of 1.0~2.0 m/s wind speeds, the curve of thermoelectric generation exhibits the most fluctuations.
