here is a pick of the pump that drives the glycol through the chiller that chills the x-ray tube. this chiller can dissipate the heat from a 5264 khu Dunlee x-ray tube in a matter of minutes... notice how the pump is insulated only around the inlet & outlet with no insulation around the motor

Btw how powerful is that pump?

I would like to insulation in a MRI machine :) some nice liquid helium in there + LN2

(Just to make it clear to everyone that is a ct scanner not the same thing thay use for looking at bones)

really not sure how powerful the pump is, but i could check tomorrow.. actually CT is better for imaging bones and MRI is better for anything soft tissue... I also do MRI's :D

but most of our smaller pumps the motor and impeller are inside the housing. Where that the motor is external and has a shaft for the impeller. thereby making the chilled fluid not effecting the motor so it donr need insulating. on our setups if we dont then the pump housing will sweat/freeze up I guess you could place the pump in a basin and drain it periodically.

i didn't get a pic of ventilation fans in the case that this pump is contained in but they are pretty heavy duty. the mag 5 pump i'm using will be insulated in the same fashion as the pump above leaving the back open and instead of a ventilation system i'm going to use active cooling in the form of a fan blowing on the back of the motor to cool it.

not realy, besides injections of contrast and the like.
