Frequently Asked Questions

Using Genie: Project Conditions

I have a range of environmental conditions, what should I tell Aavid Genie?

For conservative results, use the harshest potential conditions that are likely to affect your heat sink. Typically this means the highest elevation and highest temperature that the devices or end product will experience. Our blog post about the range of environmental conditions goes into more depth on this topic.

What does the Genie mean by “Working Envelope”?

This is the volume you have available for your heat sink. If you don’t have a fixed volume that you are working with, try using the largest preferred volume for your heat sink. Be sure to take into consideration any existing enclosures or ducts as those may dictate specific dimensions available to you. Our blog post about the working envelope and heat sink volume goes into more depth on this topic.

How does Aavid Genie define depth?

In Aavid Genie, “depth” is the flow length of the fins. In other words, the depth is the direction perpendicular to the heat sink profile.

What does the Genie mean by “Total Load of Devices”?

Your device may be powered by 100W but is only dissipating 20W as heat. The 20W is what the heat sink will need to dissipate, so that is what your input to Aavid Genie should be. Our blog post about power dissipation of heat sources details the difference.

How do I know what my Maximum Pressure Drop is?

Consider what is producing your airflow. If you aren’t using a fan, you have minimal pressure drop available to you. If you are using a fan or blower, you will need to consider a fan curve (PQ Curve). If you have an air flow for a whole system, you will need to consider the other elements in your system in relation to the fan curve.

I have multiple devices, what should I input as the Total Heat Source Size?

In the project conditions page, Aavid Genie allows you to customize the size of your device. This is only to get an estimation of the power density and its effect on heat spreading in the base. You should select dimensions that will generate a footprint area equivalent to the sum of the footprint area all the devices will have on your base.

Why does Aavid Genie only apply Radiation to Natural Convection cases?

Aavid Genie will only apply the effects of radiation to heat sinks that have no forced flow, or are removing heat by natural convection. This is because the effect of radiation is a noticeable portion of heat transfer during natural convection, but fairly insignificant in forced convection situations.

I’m not sure if I should use the Maximum Case Temperature or Thermal Resistance?

It depends upon what value you have available to you, but they both will produce a maximum case temperature. If you have neither of these values, the Maximum Case Temperature may be the easier one to calculate from the datasheet of your device. Read more about calculating these values in our blog post.
