Can a fan be used at high altitude?
This “Lessons Learned” addresses a cooling problem recently encountered while testing a fan cooled enclosure at high altitude. While we have successfully designed many systems over the years that use fans, this design was unique due to the requirement to operate at altitudes as high as 80 KFT using cold plates.
How does fan dissipation decrease at high altitude?
Rotron’s data also showed that the fan power dissipation decreases with increasing altitude from approximately 38 Watts at sea level to 10 Watts at 80 KFT.
What happens to the CFM when the altitude increases?
“As the altitude (or pressure) changes, the CFM flow through the box will remain the same if a constant speed fan is used. When the altitude is increased, the air density is decreased and therefore, the weight flow is decreased.
How is heat exchanger performance affected at altitude?
The air temperature rise (advection) and the heat exchanger performance (convection) are both adversely affected by decreasing density. By accounting for the variation in air properties, fan performance, system pressure drop, advection and convection the feasibility of air cooling at altitude can be readily determined from commonly available data.

Is it possible for a Jeep Compass to overheat?
Has anyone had their jeep overheat?Maybe been through the dealership about this issue?I’m hoping it’s only a sensor.
What to do if your Jeep Compass radiator fan is not working?
The first thing that you would want to do is locate the fuse for your Compass’s radiator fan and make sure that it hasn’t blown. If it is blown, replacing the fuse will only solve the problem for a very limited period of time. Unless the wiring issue is fixed, the fuse will blow again.
