    If you could actually make it leak free then some low pressure refrigerant would probably make more sense than water.

    Actually in many ways water is an excellent refrigerant if you don't mind working at sub-atmospheric pressure. The latent heat of vapourization is remarkably high, so the mass of refrigerant required for a given power is low, and it's non-toxic, doesn't do global warming, etc. It does, however, have one problem. It freezes…

    Also quite corrosive if there is oxygen available.

    true. In fact, there are remarkably few things that water won't attack, given an oxidizer such as oxygen and the right pH… It's about as close to a universal solvent as there is (although it can be slow).
