measure temperature on a Heat Sink

[CADone]

Hi,

I have few LEDs (Heat source) on a the base of a Heatsink. While the LEDs are turned ON, I need to simulate the Heat on the heatsink. The various temperatures on the various areas of the Heatsink.

1. Which is the addin I need to use for this?
2. Please suggest a bit on how to interpret the results & Corrective actions?

Thx

1. Cosmos (Simulation) can do this assuming you have above the free CosmosWorks. Any FEA package that can perform thermal analysis could also be used. (some free)
2. One of the first tutorials for the software probably has a similar analysis.

I hope this helps.

Rob,
Thanks for the reply. I noticed that there was another addin called Floworks. When I read the synopsis of this addin, it appeared to me that it could me more appropriate to my application than the simulation addin.

Basically, I my application I have electrical fixture. The lamp is a source of heat ( & Light ). The heat from the lamp has to be transfered to atomosphere via heatsink. DUring design Its important to measure various temp zones through out the assly.

Thx

Unless you are trying to model flow paths of wind current I believe that computational fluid dynamics (CFD) would be overkill. But it really depends on the complexity of your system and the cost of failure. If this is to design a heat sink for every Dell made then it's probably worth it but if it is to do this

then hand calcs and possibly some FEA are in order. I hope this helps.
