Chinatungsten offers special high conductivity and low thermal expansion metals and ceramic materials. All materials are available as finished components and in sheet form. Metals are available either as composites or as laminated sheets.<br /> A heat spreader is most often simply a copper plate, having high thermal conductivity. Functionally, it is a heat exchanger that moves heat between a heat source and a secondary heat exchanger whose surface area and geometry are more favorable. By definition, the heat is "spread out", such that the secondary heat exchanger increases the heat capacity of the assembly. These properties make it a better match for an air heat exchanger, since the low heat conduction for air in convection is matched with higher surface area.</p> <p>A tungsten copper heat spreader is generally used when the heat source tends to have a high heat-flux density, (high heat flow per unit area), and for whatever reason, heat can not be conducted away effectively by the secondary heat exchanger. For instance, this may be because it is air-cooled, giving it a lower heat transfer coefficient than if it were liquid-cooled. A high enough heat exchanger transfer coefficient is sufficient to avoid the need for a heat spreader.</p> <p>Two memory modules encased in aluminum heat spreaders. The use of a heat spreader is an important part of an economically optimal design for transferring heat from high to low heat flux media. Examples include:</p> <p>A copper-clad bottom on a stove-top cooking container made of steel or stainless steel. <br /> Air-cooling integrated circuits such as a microprocessor. <br /> Air-cooling a photovoltaic cell in a concentrated photovoltaics system.</p>  <div class="clear"></div> </div>   <div class="related-posts clearfix"> <h4 class="related-posts-more">Related Products:</h4> <div class="nobottommargin"> <div class="mpost clearfix"> <div class="entry-image"><a href="http://www.tungsten-copper.com/tungsten-copper-submount.html" target="_blank"><img src="pic/Tungsten Copper Heat Sink.jpg" alt="Tungsten Copper Submount Picture" title="Tungsten Copper Submount Picture"></a></div> <div class="entry-c"> <div class="entry-title"> <h4><a href="http://www.tungsten-copper.com/tungsten-copper-submount.html" target="_blank">Tungsten Copper Submount</a></h4> </div> <div class="entry-content">The coefficient of thermal expansion (CTE) of the composite can be designed by controlling the content of tungsten, matching that of the materials, such as Ceramics (Al2O3, BeO), Semiconductors (Si), Metals (Kovar), etc. </div> </div> </div> <div class="mpost clearfix"> <div class="entry-image"><a href="http://tungsten-copper-dart.com/tungsten-copper-dart-billets.html" target="_blank"><img src="pic/tungsten-dart-001.jpg" alt="Tungsten Copper Dart Billets Picture" title="Tungsten Copper Dart Billets Picture"></a></div> <div class="entry-c"> <div class="entry-title"> <h4><a href="http://tungsten-copper-dart.com/tungsten-copper-dart-billets.html" target="_blank">Tungsten Copper Dart Billets</a></h4> </div> <div class="entry-content">Tungsten alloy Billets are actually tungsten cylinder rods after surface grinding by center-less processing, and their weights are varied from different tungsten contents and rod sizes. </div> </div> </div> <div class="mpost clearfix"> <div class="entry-image"><a href="http://tungsten-copper-block.com/tungsten-copper-W70-blocks.html" target="_blank"><img src="pic/tungsten-copper-W70-blocks.jpg" alt="Tungsten copper W70 block Picture" title="Tungsten copper W70 block Picture"></a></div> <div class="entry-c"> <div class="entry-title"> <h4><a href="http://tungsten-copper-block.com/tungsten-copper-W70-blocks.html" target="_blank">Tungsten copper W70 block</a></h4> </div> <div class="entry-content">Tungsten copper W70 block has excellent mechanical strength and electric erosive resistance. </div> </div> </div> <div class="mpost clearfix"> <div class="entry-image"><a href="http://tungsten-copper-military.com/Tungsten-Copper-Military-Nozzle.html" target="_blank"><img src="pic/tungsten-copper-military-nozzle-02.jpg" alt="Tungsten Copper Military Throat Insert Picture" title="Tungsten Copper Military Throat Insert Picture"></a></div> <div class="entry-c"> <div class="entry-title"> <h4><a href="http://tungsten-copper-military.com/Tungsten-Copper-Military-Nozzle.html" target="_blank">Tungsten Copper Military Throat Insert</a></h4> </div> <div class="entry-content">Tungsten copper nozzle is the important part of thrust chamber.
