Thermal Flow simulation for PCB

Jatin Sharma Feb 25, 2015 5:36 AM

I am doing a thermal flow simulation study for a PCB enclosed in a closed box, i have datasheet of the components that are being used.

I am not able to figure out what values i would be putting in the simulation for temperature of the individual components.

I really need some help here.

Thanks...

what is the goal of your analysis? generally with electronics cooling it is to find the temperature of the components.

so normally you would input what the power is going into the components and based on the flow, you will get the temperature of the components.

  Hi Jered,
  
  Thanks for the reply, í am running this kind of simulation for the first time. I have an enclosed PCB inside a plastic part, i want to check what temperature it will reach in a certain time. So, that i can design the heat sink accordingly. I have datasheets of the components, but i am not able to figure out what values to put as inputs for temperature/power. Because as a golden rule for simulation, if i will put garbage, i will get garbage.
  
  Thanks,

    you should talk to your EEs. they will be able to tell you what power the components will use
