TL;DR: Inverse heat conduction method (IHCM) is one of the most effective approaches to obtain the boiling heat transfer coefficient from measured results in this paper, which focuses on its application in cryogenic boiling heattransfer.
Abstract: Inverse heat conduction method (IHCM) is one of the most effective approaches to obtaining the boiling heat transfer coefficient from measured results. This paper focuses on its application in cryogenic boiling heat transfer. Experiments were conducted on the heat transfer of a stainless steel block in a liquid nitrogen bath, with the assumption of a 1D conduction condition to realize fast acquisition of the temperature of the test points inside the block. With the inverse-heat conduction theory and the explicit finite difference model, a solving program was developed to calculate the heat flux and the boiling heat transfer coefficient of a stainless steel block in liquid nitrogen bath based on the temperature acquisition data. Considering the oscillating data and some unsmooth transition points in the inverse-heat-conduction calculation result of the heat-transfer coefficient, a two-step data-fitting procedure was proposed to obtain the expression for the boiling heat transfer coefficients. The coefficient was then verified for accuracy by a comparison between the simulation results using this expression and the verifying experimental results of a stainless steel block. The maximum error with a revised segment fitting is around 6%, which verifies the feasibility of using IHCM to measure the boiling heat transfer coefficient in liquid nitrogen bath.

TL;DR: In this paper, a battery thermal management system (BTMS) with heat pipe and phase-change liquid to control temperature and inhibit thermal runaway (TR) is presented. But, the results show that the proposed BTMS inhibits TR and its propagation effectively, the temperature of overcharge-cell surface remains below 185°C, and it remains above 60°C for only 14

TL;DR: In this article, a two-component heat transfer fluid comprising a carrier fluid and a plurality of discrete reversible latent energy transition material particles is proposed to obtain enhanced heat transfer in a closed loop thermodynamic system, where the fluid slurry is circulated about the loop and the loop is tuned so that a minimum temperature differential exists between the thermal source and sink.
Abstract: A method of obtaining enhanced heat transfer in a closed loop thermodynamic system is disclosed. A two-component heat transfer fluid comprising a carrier fluid and a plurality of discrete reversible latent energy transition material particles. The fluid slurry is circulated about the loop and the loop is tuned so that a minimum temperature differential exists between the thermal source and sink in order to maximize the latent heat transport by adjustment of the heat transfer fluid flow rate, the rate of thermal energy input into the heat transfer fluid and the rate of cooling of heat transfer fluid.

TL;DR: In this paper, a thin capillary liquid transport structure is encased within relatively thick sections of a plastic bonded aluminum powder wick, formed of two layers of fine mesh screen separated only by small, randomly located, powdered metal granules.
Abstract: A high permeability wick structure for heat pipes. A thin capillary liquid transport structure is encased within relatively thick sections of a plastic bonded aluminum powder wick. The capillary structure is formed of two layers of fine mesh screen separated only by small, randomly located, powdered metal granules. The capillary liquid transport structure can be built in numerous cross sectional configurations, including annular rings or spoke like radial sections.
