Heat pipes are efficient heat transfer devices which can transport the heat over a distance with a small temperature gradient using the principle of the latent heat of vaporisation [1]. With the development of solar energy, the technology of combining the heat pipe with solar collector is widely being used in engineering and industrial applications. For instance, evacuated tube solar thermal collector [2], flat plate solar thermal collector [3] and Photovoltaic/thermal solar collector [4] can all integrated with the heat pipe. The MCHP can transfer the collected solar thermal energy from its evaporation end to the condensation end in order to produce hot water or hot air.Currently, the flat plate microchannel heat pipe (MCHP) is one of the most preferred heat pipes since it presents a greater heat transfer characteristics and better performance over the small temperature gradients owing to its micro-channel structure [5,6]. In addition, because of its flat-panel structure, which effectively combines with solar energy, it has gained the attention of the researchers. Deng et al. proposed a novel flat plate MCHP solar collector which produced excellent thermal performance during the experiments [7,8]. Hou et al. also studied a novel photovoltaic-thermal MCHP collector based on the experiment and simulation [9]. Li et al. presented a novel MCHP evacuated tube solar collector for the power and hot water generation [10]. Zhu et al. designed a flat-plate MCHP solar air collector [11]. Zhu et al. investigated the significance of using a MCHP heat exchanger for heat recovery in Simulation and experiment on thermal performance of a micro-channel heat pipe under different evaporator temperatures and tilt angles Guiqiang Li a, *

A numerical simulation model of embedded liquid microchannels for cooling 3D multi-core chips is established. For the thermal management problem when the operating power of a chip changes dynamically, an intelligent method combining BP neural network and genetic algorithm is used for distribution optimization of coolant flow under the condition with a fixed total mass flow rate. Firstly, a sample point dataset containing temperature field information is obtained by numerical calculation of convective heat transfer, and the constructed BP neural network is trained using these data. The “working condition–flow distribution–temperature” mapping relationship is predicted by the BP neural network. The genetic algorithm is further used to optimize the optimal flow distribution strategy to adapt to the dynamic change of power. Compared with the commonly used uniform flow distribution method, the intelligently optimized nonuniform flow distribution method can further reduce the temperature of the chip and improve the temperature uniformity of the chip.
