natural graphite sheet heat sinks with embedded heat pipes

Thermo Cool

An advantage of folded fin heat sinks is the ability to combine aluminum and copper to tailor the performance of the heat sink to the particular application. If the heat must be spread over a large heat sink base, copper can be used for its high conductivity, yet the heat sink fins can be produced from aluminum, due to its low weight and cost.

If you're using graphite sheets, you could probably also use some heat pipes. Order them together and save on shipping! Third-party verification document showing 1820.559W/mK in the raw material which lowers to 1600W/mK once packaged into the sheet product.

Generating Power from Pavement

They have also looked into using series of heat sinks similar to those used in some residential floorboard heating systems. Professor Mallick and others on his research team began exploring the power generation capacity of asphalt using a series of computer models, but have moved on to small and large scale tests in the laboratory and outdoors in natural conditions.

Graphite Heatsinks: Like Copper Without the Weight

These natural graphite-based heatsinks have been used trouble-free in production power electronics applications since August 2003. To date, production applications include the cooling of discrete T0-247 devices dissipating approximately 50 W; Ku-band satellite transceiver units dissipating about 210 W; and Peltier devices handling about 150 W.

By incorporating heat pipes onto the surface of an air cooled heat sink, high concentration of heat from power electronics can be spread out over a larger area are very quickly. This technique can greatly improve the cooling performance of the heat sink for applications such as SiC and Power Amplifier.

Natural Graphite Sheet Heat Sinks with Embedded Heat

Natural graphite sheet (NGS) is a candidate material for lightweight, high-performance heat sinks. We show that the low through–plane thermal conductivity can be mitigated by using heat pipes. In the measured configuration, the thermal resistance of an NGS heat sink with embedded heat pipes is comparable to that of a geometrically-identical aluminum one.

A review on the applications of micro

In modern heat transfer systems, thermal storage not only causes the balance between demand and supply, but also improves the heat transfer efficiency in these systems. In the present study, a comprehensive review of the applications of micro- or nano-encapsulated phase change slurries (MPCMs/NPCMs), as well as their effects on thermal storage and heat transfer enhancement, has

Thermal properties of graphite

The thermal properties of conductivity and expansion are strongly influenced by the anisotropy of the graphite crystal. The thermal conductivity (K) is the time rate of transfer of heat by conduction. In graphite, it occurs essentially by lattice vibration and is represented by the following relationship: Eq (1) K=bCpvL Where b= a constant C= specific heat per unit volume of the crystal v

Thermal Management Options for Mobile Devices

A more sophisticated type of heat sink, a heat spreader, works by transferring heat from its source to a secondary heat exchanger featuring a larger surface area and geometry. Typically, a flat plate that's formed out of a thermally conductive material, such as graphite, is used to draw heat and pass it to the mobile device's external metal chassis and, ultimately, into the environment.
