Oil cooling, water cooling
Thread Content
I’m ignorant; I’ve been working for some time now but still don’t understand many things. Fortunately, I have my colleagues here to help me:D Now I would like to ask: I’ve seen that the cooling systems for fan shafts can be either oil-cooled or water-cooled. I’d like to ask the experts what requirements there are in this regard
There are mainly two points: 1. The boiling points of the two media are different; the boiling point of oil is much higher (water boils at 100 degrees, and the boiling points of heat transfer oils with different compositions also vary). Therefore, oil cooling can be used in applications where temperatures are above 100 degrees； 2 The difference in thermal conductivity is too large; oil has a poorer cooling effect than water. Water cooling is economical and clean, but oil cooling can be used for applications at higher temperatures
