“…The vapor moves to the condenser by convection and changes into liquid, which flows back to the evaporator by the wick structure that provides capillary pumping for the circulation. The design and simulation of the heat pipe are based on the methodology presented in [18] and [19]. The requirement for capillary pumping was not considered in this work, as it was assumed that the heat pipes were correctly designed for the use in the battery module in question.…”

In the design and operation of batteries, effective heat transfer and protection against high operation temperatures are significant issues affecting the lifetime of the battery. This is particularly the case for batteries intended for hybrid machines, where the peak power and current requirements are high. This paper introduces a structure of the thermal protection system for the high-power lithium-ion batteries to be applied to hybrid machines and a methodology for their optimization. The proposed structure is based on the use of metal plates and heat pipes, providing an opportunity to decrease the nonuniform temperature distribution in pouch-type cells. The efficiency of the proposed thermal control system is verified by modeling in Comsol Multiphysics, which is connected to MATLAB for the optimization of the placement and number of heat pipes. Multidimensional unconstrained nonlinear minimization is applied during the optimization in MATLAB.

“…Therefore, in the modeling, the heat pipe is considered as a thermal superconductor with a very high thermal conductivity in the axial direction. The thermal conductivity of the heat pipe in the axial direction is calculated similarly as in [18] and [19] by using the following equation:…”

“…The results showed the addition of Al 2 O 3 nanoparticles in DI water reduced the thermal resistance by about 15 and 22% for 10 and 25 W heat loads respectively compared with DI water. Elnaggar et al (2011) used a finned heat pipe of U-shape for CPU cooling in PCs. Air velocity, power input and inclination angle were varied to study the thermal performance of heat pipe.…”

“…In addition, the specific simplified models in the literature are shown in Table 1. Elnaggar et al [22] simulated the U-shape heat pipes radiator used for computer cooling by the finite element simulation method. The effects of the air velocity, power input and heat pipe orientation on the performance of finned heat pipes were analyzed.…”

With the rapid increase of power densities of electronic components, the traditional heat dissipation method of air forced convection has reached a heat transfer limit. As efficient phase change heat exchangers, vapor chambers have become an important guarantee for the development of high-power electronic components. Aluminum vapor chambers have become the future development trend because they are more lightweight and less expensive. In order to study the suitable simplified model of the aluminum vapor chamber in the radiating system, the testing system is established to test the thermal characteristics of the vapor chamber. First, six simplified models of the vapor chamber are proposed. Then, the thermal characteristics of the simplified models are simulated by STAR CCM+ software. Next, the error of the thermal resistance of the simplified model and the real vapor chamber is analyzed. Finally, a most suitable simplified model is obtained in the cooling system.
