Hi, Please help me. Which is the temperature that needs to be changed for the internal device to cool down. I tried many variants but the result is the same. SimScale Login Log in to your SimScale account. SimScale makes high-fidelity engineering simulation technically and economicall…

Hey there, thanks for the explanation, it is clear now! I think you could improve your model here, please follow this suggestions: Reduce the flow region to fit only the chest. In this way, the fan locations would be only faces that we will use later for boundary conditions. Apply a Power source …

Hi Oliver! Thanks for using the forum! This looks like a very interesting project, and I would like to help. Could you please elaborate on the description? What is the cooling strategy? What temperature can be controlled?

Hi! Naturally. it is a chest containing IT units. The whole crate is in an air-conditioned room with this air I want to cool the inside of the crate. My idea would be that three fans would do this task on both sides. I want to keep the devices from boiling with twenty degrees of air. This twenty de…

Hi Ggiraldof! Thank you for trying to help. I tried to go through this but I mess something up. You can view? The simulation runs nicely but the temperature is not a good thing SimScale Login Log in to your SimScale account. SimScale makes high-fidelity engineering simulation technica…

Hello, The fan curve configuration looks unexpected to me. Usually, the custom fan boundary condition is defined to the inlet OR to the outlet (but not both). For instance, let’s say that we have a custom fan BC for the inlet. For the outlet, I would normally expect either a pressure outlet bounda…

Hello, I tried what you recommended but the same result. The temperature has dropped but the body is now showing no temperature change. What could be the problem? I want to achieve that if I put in an IT device that heats up to 50 degrees Celsius, then these fans will be able to cool it down. It…

Well, since the power source is being defined to a huge volume (instead of a small part, like a chip), then the temperatures will be on the low side. Furthermore, given the large thermal conductivity of aluminum, there won’t be large gradients. Feel free to set some result controls , otherwise you w…

Thanks for the answer! What do you think about giving it as a wall? I mean, it’s a server unit that works at 50 degrees. I care if I put one or more IT units in a box that is blown from both sides by fans to be satisfied with this cooling or larger fans need answers.

Well, it depends on your objectives and the scenario that you have in real life. What I can tell you is: for electronics cooling, the typical approach is to use a power source (only to the part which is effectively dissipating heat).

Hi there!

I suggested above to perform a test with simple flow inlet/pressure outlet BCs, can you please send me the link to such model?
