Solution without heat pipe, higher temperature gradient and max temperature
Solution with heat pipes integration to the base of the heat sink, reduced temperature gradient and max temperature
Heat pipe integrated solutions will help to reduce overall temperature of your system by spreading the heat more evenly with lower temperature gradient. This is especially obvious when you have a very small heat source with high power (10 x 10 mm, above 50W).
Heat pipe integrated heat will be proposed for 3 types of applications:
1.) Limited space (notebook, laptop application)
2.) PCB with a lot of devices obstructing convection heat transfer OR need to transfer the heat to casing of application to further enhance heat transfer.
3) when customer asked for copper heat sink, we will proposed heat pipe integration to keep the weight and cost in control.
