Nano module thermal questions

[mhaskell]

I am working on the thermal design of the product which is using the nano module. We are operating with very little thermal margin, and need further detail than is provided in the jetson thermal design guide.

Could you supply the following?
• Do you have an existing CFD model of the module? If so in which format?
• Can you provide the JEDEC thermal package information for the TEGRA and DDR4 modules?
• The average power dissipation for the TEGRA and DDR4 modules, along with any other significant components. In particular, the components rated at 85°C max case (C1217, C344, U4, L502).
• Total module power dissipation, average and worst case.
• Board conductivity in XYZ dimensions.

Thank you.

Hi, what we provide till now are all in DLC, please check the docs there first: [url]https://developer.nvidia.com/embedded/downloads[/url]

Could you supply the following?
• Do you have an existing CFD model of the module? If so in which format?
We do thermal analysis on board / module level using thermal analysis software “ICEPAK”.

• Can you provide the JEDEC thermal package information for the TEGRA and DDR4 modules?
We can provide Theta JC and Theta JB values, there is detail info in thermal design guide.

• The average power dissipation for the TEGRA and DDR4 modules, along with any other significant components. In particular, the components rated at 85°C max case (C1217, C344, U4, L502).
For thermal solution we always specify “Average Power enabled at steady state”, the thermal control logic is listed in thermal design guide.

• Total module power dissipation, average and worst case.
Max 10W Total module power is based on Passive thermal solution – no fan. This is steady state average power dissipation. Customer can mount their own cooling fan and increase the max total module power limit

• Board conductivity in XYZ dimensions.
Please refer to thermal design guide for more info.

Thank you.
