Process :stamping + sodering+insert heat pipe .
Folded fins are created by a progressive stamping method. The fins are then bonded to a base with thermally conductive epoxy, brazing, welding, or similar metallurgical bonds, to create a heat sink. 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.
A typical heat pipe consists of a copper tube in which the inner walls are lined with a wick structure. The heat pipe is charged with de-ionized water and then vacuum sealed. This gives the water a lower boiling point. When the heat pipe is heated at one end, the working fluid evaporates from liquid to vapor (phase change).The vapor travels through the hollow core of the heat pipe to the other end of the heat pipe, where heat energy is being removed by a heat sink or other means. Here, the vapor condenses back to liquid and releases heat at the same time.
The liquid then travels back to the original end of the heat pipe via the wick by capillary action.
Folded fin heat sinks can be customized with heat pipes and integral ducts to enhance thermal performance
The applications of folded fin heat sinks :
High density cooling of power modules
IGBT’s or transistors
Heatsink design and analysis
