Background technology
Radiator is widely used in LED, plasma display, computer CPU, IGBT, IPM,, frequency converter etc.Along with the increase of power, to radiator require increasingly high.With LED is example, in certain temperature range, and 10 ℃ of every reductions, its life-span just doubles.Existing heat spreader structures is complicated, and weight is big, volume is big, and useful life is short, and radiating effect is not good.
The utility model content
The purpose of the utility model provides that a kind of radiating rate is fast, in light weight, easy to assembly, cost is low and can guarantee the radiator new radiator of cooling rapidly.
The technical scheme of the utility model is: a kind of new radiator; Comprise radiator (1); It is characterized in that said radiator (1) is three-dimensional netted graphite foam or reticulated vitreous carbon (RVC); Said three-dimensional netted graphite foam or reticulated vitreous carbon have the open-celled structure that is interconnected, and carbon content is 10%～100%.
Below radiator (1), be provided with heat-conducting layer (2).
Said radiator (1) is tabular, block, tubulose or radial with heat-conducting layer (2).
Said radiator (1) is provided with heat pipe (5) or fan (6).
The effect of the utility model is: the radiator of new radiator is three-dimensional netted graphite foam or reticulated vitreous carbon, and three-dimensional netted graphite foam or reticulated vitreous carbon have the open-celled structure that is interconnected.Have following characteristics: (1) because its material is three-dimensional netted graphite or reticulated vitreous carbon, material has high-termal conductivity; (2) because be open-celled structure, make heat sink material have the area of dissipation of super large; (3) open-celled structure makes it very easily form convection current with surrounding environment, thereby radiating rate is accelerated.
Add heat pipe on the three-dimensional netted graphite foam (or reticulated vitreous carbon), purpose is to be transmitted to the heat of thermal source on the radiator of above-mentioned material through heat pipe fast.The purpose that adds fan is to accelerate the heat exchange of radiator and surrounding environment, thereby reaches the purpose of quick heat radiating.
In general, have the advantages that the diffusing speed of radiator is fast, in light weight, easy to assembly, cost is low and can guarantee the rapid cooling of radiator.
