low profile heat sinks copper heat sinks fuse holders LOW PROFILE HEAT SINKS Low profile heat sinks assemblies are perfect for meeting this challenge. The low profile heat sink removes the heat from the heat source to the fin stack where it is dissipated to the environment either by nature convection or forced convection. Most of the assemblies are consist of low profile heat sinks or metal plate, heat pipe, slim blower,or thermal interface material. Low profile heat sinks are designed to meet the specific demands of tough-to-cool electronic components with low air velocity flows. The above standard series were designed as low profile heat sinks and do not necessarily meets the specifications of any particular machine. Use of these "low profile heat sinks" is the responsibility of the customer. The new series fin pattern was designed for low profile, high performance heatsinks. To meet the next generation thermal requirements with a low profile heat sink, we will describe three heat sink technologies. Additionally, the thermal performance achieved by these type of prototype low profile heat sinks exceeded the thermal performance levels for all the submitted competitive designs and prototypes, which utilized similar fluid phase change technologies.
