High power heat sink with heat pipe advantages
The heat sink with heat pipe assembly was able to effectively dissipate the 6kW of heat while maintaining the IGBT under their rated temperature limits. In comparison, the extrusion was not able to meet the requirements.
The thermal resistance of the heat sink is determined by the thermal conductivity of the material and the effective area within the volume. When the volume of a solid aluminum or copper heat sink reaches 0.006m cubed, increasing its volume and area does not significantly reduce the thermal resistance. For discrete semiconductor devices with dual cooling, the thermal resistance of air-cooled all-copper or all-aluminum radiator can only reach 0.04℃/W, while that of heat sink with heat pipe can reach 0.01℃/W. Under the condition of natural convection cooling, the performance of heat sink with heat pipe can be improved more than ten times than that of solid heat sink.
With heat pipe as the core, this heat pipe thermal module, which is composed of heat sink, zipper fin and fan, can solve the heat dissipation problem caused by narrow space or too concentrated heat. The key parts is heat pipe that is an efficient heat conduction device made by using the principle of low pressure liquid phase change. Its heat transfer efficiency is dozens to hundreds of times that of traditional metals, can quickly take heat away from the heat source.
Heat pipe heat sinks in the power electronics field can be classified as follows according to the techniques used:
Heat pipe+Profile :Made from the base material of the thick tubular aluminum sleeve inserted into the fluid treatment tube, the aluminum fin material completely wraps the heat pipe , so there is no risk of electrical corrosion at the root of the fin (between the heat pipe and the fin). As the only interface between heat and cold sources, extruded fin heat pipe is the core of heat transfer. When the heat transfer capacity of the two liquids is far apart, fins or grooves can be used for heat exchange between the two liquids, and fins can be added to the surface in contact with air to increase the heat flux density between the two fluids.
Heat pipe+zipper fin heat sink
The fins are welded, made of stamping material aluminum or copper, and folded into a shape with interlocking slots.The folding fin can transfer high thermal energy and has more than 3000 different configurations. Larger surface area, more flexible design and more stable structure than extruded fins, allowing very high fin density and length-width ratio, thus increasing surface area and better cooling. Zipper fins also increase design flexibility, especially for pipes that integrate heat pipes, fans, or blowers
Heat pipe+ Copper plate
Heat pipe heat sink solved such as high power CPU, laptop CPU far end heat dissipation, mature technology, high reliability, the cost is also rapidly reduced with the growth of the consumption, the industry has begun to widely use at present. Some manufacturers in their high power consumption IC devices, high heat flux density modules and other applications have also adopted this kind of heat dissipation problem.
