A study of flat plate heat pipe for LED array related to MCPCB design
The study of flat plate heat pipe for LED array aim
We have known MCPCB design usual use metal material, is there any alloy make a MCPCB?
In order to verify the performance of diamond powder PCB-FPHP, our experimental measured the PCB-FPHP and common MCPCB conducted with 3 different materials include Cu, Al and FPHP by IR camera.
The reasoning of flat plate heat pipe for LED array MCPCB design
If you have some MCPCB design experience, you may the reasoning of this study not easy.
First of all you should choose the material can heat dissipate very fast.
In this study, we use 30% diamond powder as the filler of dielectric layers and combined the PCB and flat plate heat pipe (PCB-FPHP) without metal base to enhance the effective thermal conductivity.
The result of flat plate heat pipe for LED array MCPCB design
Till read this part, you have known the most content of this study.
But most important is the result of this study, because it related to the MCPCB design material cools.
The experimental results show that the thermal resistance of PCB-FPHP is 36%, 78% and 86% lower than MCPCB-FPHP, MCPCB-Cu, and MCPCB-Al respectively.
It is obviously that the thermal resistance of a metal base and the thermal grease cannot be neglected, especially in high power application.
