Which fan placement offers the most airflow for cooling electronics?
AI Thread Summary
The discussion centers on optimizing airflow for cooling electronics using two identical fans. The first arrangement is noted for overcoming more pressure, while the second arrangement is recognized for producing greater airflow. Effective cooling depends on achieving high mass flow rather than just high air velocity, particularly at critical locations. The design of vent placement significantly influences pressure differentials and overall cooling effectiveness. Ultimately, relocating exhaust vents to higher positions in the second option is suggested to enhance cooling performance.
Venus does not have a magnetosphere, so the Galactic Cosmic Rays (GCRs) environment shall be much worse than in a LEO environment. Looking to the std radiation models for Venus, the standard radiation-hard space level electronic component with tested immunity LET = 85 MeV-cm2/mg seems not enough, so, for example, a 1cm2 Si die will suffer considerable flux above this level during a long mission (10 years for example). So, the question is, usually we are not paying attention to latch-up...
Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile:

This is a fully stacked Starship (top) and Super Heavy (bottom). A couple of too-small-to-see cars near the bottom for scale, I also added a Saturn V and the Statue of Liberty for comparison. 120 meters tall, about 5000 tonnes when fully fueled. Twice the mass and over twice the thrust of Saturn V. The largest rocket ever built by mass, thrust, height, and payload capacity. N1 had the largest diameter.[/size]
But its size is not the revolutionary part. It is designed...
