Not certain how well it would work for the cooling application, but in the past I used windshield washer water pumps (and their plastic fluid containers) to inject water into a turbocharged 1976 Honda Civic.  The pump system  was designed for “hostile” environment use under the hood of a automobile.  Not certain whether it develops enough pressure to give a good atomized spray.  But, they were relative cheap and available.

This hobby and list sure does bring together a varied assortment of professions.
    I might just try one of those later if no one else has yet. I have allot to do before I'm there yet, so I'll not worry about it yet.

Laprascopic Surgery is the surgery through the cameras.  They inflate the abdominal cavity with CO2 and insert instruments through small holes to take out the appendix or gall bladder or whatever.  The pump used brings in the irrigation fluid, which is later sucked back out.

 

Someone mentioned that duty cycle may be an issue.  That is probably true because in surgery the pumps are never used more than a minute or two, and are meant to be disposable.  They also may not last very long in an under cowl or corrosive environment.
