Porous Structures in Heat Pipes

2017/4/11This work deals with heat pipes with porous wick structures and experiments depending on the wick structure porosity, because the porosity is one of the wick structure properties which has effect on the heat transport ability of the heat pipe. The work describes manufacturing porous wick structures for wick heat pipe by sintering of copper metal powders with various powder grain size

Thermal conductivity

The thermal conductivity of a material is a measure of its ability to conduct heat. It is commonly denoted by k {displaystyle k}, λ {displaystyle lambda }, or κ {displaystyle kappa } . Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity. For instance, metals

Feel the Heat: Thermal Design Trends in Medical Devices

In a heat pipe heat exchanger, heat spreads through a heat pipe and is dissipated through a finned heat sink, where it is rejected to the ambient atmosphere. T he impressive capabilities of twenty-first century medical technology, from imaging equipment to surgical instruments and automated immunoassays, are in many ways a tribute to the advances in microprocessor computing power.

Isothermal characteristics of a rectangular

The isothermal characteristics of a rectangular parallelepiped sodium heat pipe were investigated for high-temperature applications. The heat pipes was made of stainless steel of which the dimension was 140 m(L) 95m(W) 46m(H) and the thickness of the container was 5 mm. Both inner surfaces of evaporator and condenser were covered with screen meshes to help spread the liquid state working

Heat Pipes and Thermosyphons

Heat pipes are highly effective passive devices designed to transfer large quantities of heat through a small cross-sectional area over considerable distances, while operating nearly isothermally. Heat pipes are composed of a sealed container, lined internally with a wick and filled partially with a working fluid.

Heat Pipes for Thermal Management

Everything you need to know about heat pipes Heat Pipes are one of the most efficient ways to move heat, or thermal energy, from one point to another. These two-phase systems are typically used to cool areas or materials, even in outer space. Heat pipes were first developed for use by Los Alamos National Laboratory to supply heat to and remove waste heat from energy conversion systems.
