This discussion explains the nuances well: https://english.stackexchange.com/questions/28752/whats-the-difference-between-collaborate-and-cooperate

They are different. 'Collaborate' means working together - you'd use it for scientists from different fields or institutions teaming up to work on a research project. (NB - it's also used in a negative sense in the context of war, when citizens of an occupied country help the enemy - but I don't think this is the use you are thinking of) 'Co-operate' means to act in a way which is helpful to another party, to do what that other party wants them to do, or not to obstruct them. You might see a notice somewhere asking people not to open the windows while the airconditioning is on because the company wants to save energy, and this would be followed by the phrase 'thank you for your co-operation' ie don't prevent us from saving energy. With 'co-operate' it's always a case of A wants to do something, and B acts in a way which doesn't obstruct them. That said, there may be cases where either could be used.

Simply, and without any sort of language qualifications or anything, I would say that 'collaborate' means two or more people putting intellectual ideas together, and 'cooperate' means two or more people working together to achieve a pre-set task.
