ISO7741: Risk for immersion cooling analyzement

Erick Hong

Part Number: ISO7741

Tool/software:

Hello experts, 

I am Erick, sales in Taiwan, I would like to kindly request for your help with analyze or give me any feedback if there could be any risk to put ISO7741DWR in immersion cooling.

The immersion cooling process is soaking the server in a non-conductive liquid, conducting heat through direct contact with the hot part and the flow of the liquid, eliminates the need for dissipating the heat part.

The below information may help you to analyze the impact putting device in  the selective immersion cooling.

    Hello,

    Thank you for your patience.

    We have not specifically tested with the mentioned liquid, so we cannot guarantee anything, however what we believe to be the case is the following:

    From a high voltage perspective, The liquid is non-conducting, and I would assume by definition be less conductive than air for high voltage purposes. So theoretically this should be better to reduce through-air arcing for high voltage performance.

    In terms of physical degradation, we would recommend to check with the vendor on certificates or data in relation to “non-corrosive” or “non-reacting” used in these environments and use-cases. 

    Overall, we would in general think this is ok but again cannot guarantee our device interaction with the fluid you have mentioned.

    Regards,
