A beginner in heat exchange has a question
Thread Content
Dear experts, I work in the field of vehicle cooling system design. The radiators used are generally tube-and-fin type radiators; only the cooling medium flows through these radiators. The engine oil inside the engine can be considered a heat source, and the heat carried away by the cooling medium passes through the radiator, after which forced convection by a fan is used to dissipate this heat into the atmosphere. I’ve made an analogy: the oil circuits inside the engine and the water circuits of the cooling medium function in a similar way to those in a shell-and-tube radiator. I have a question: how is the heat carried away by the cold fluid ultimately dissipated? Is there an external water tower that continuously supplies cold fluid, or is it also dissipated through forced air cooling? I don’t have much experience with industrial cooling systems, so I would be very grateful if you could help me understand this !
It depends on how much cooling capacity you need; if that isn’t sufficient, you can choose a different refrigerant

So that means it’s directly dispersed into the environment, right? If a balance can be achieved, then no external forced cooling is needed, is that what it means? So if balance cannot be achieved, how can heat be dissipated? Could you give some specific examples? Thank you
Cars have water cooling systems and fans to cool them down, as well as air cooling that occurs during driving. For normal use, a car is sufficient; as for extreme situations, it’s hard to say
The flow of air carried away the heat.
