Abstract
Disclosed is a liquid cooling system for use with MRI positioned video projectors to dissipate heat from the projector light source through liquid cooling. The system includes a heat sink body for mounting to the projector light source, the heat sink body constructed of a material to transfer heat away from the projector light. A remotely mounted motor-driven pump provides fluid circulation, the pump is constructed and/or mounted so as to not to be effected by the MRI magnetic field. The pump is coupled to the heat sink block by use of flexible tubing that is constructed and arranged to provide heat transfer to the environment thereby maintaining the projector light source temperature at a reduced level. A liquid reservoir is fluidly coupled to the pump intake for use in maintaining liquid levels at an optimum position.

An apparatus for use in cooling a video projector light source in an MRI environment, the apparatus comprising:
- a heat sink block having an internal chamber with an inlet and an outlet, said heat sink block constructed and arranged for securement to a video projector light source mounted within a video projector housing;
- a fluid pump remotely positioned from said video projector housing, said fluid pump having an outtake coupled to said heat sink block input, and pump intake coupled to said heat sink output;
- and
- a pump motor electrically coupled to said video projector to cause operation of said pump for recirculating fluid between said pump and heat sink block when the video light source is operating;
- wherein heat from a projector light source secured to said heat sink block is transferred to the fluid and dissipated during the recirculation of the fluid.
An apparatus for use in cooling a video projector light source in an MRI environment, the apparatus comprising:
- a heat sink block having an internal chamber with an inlet and an outlet, said heat sink block constructed and arranged for securement to a video projector light source mounted within a video projector housing;
- a fluid pump positioned at least ten feet from said video projector housing, said fluid pump having an outtake coupled to said heat sink block input by a first flexible tube, and said pump intake is coupled to said heat sink output by a second flexible tube;
- a pump motor electrically coupled to said video projector to cause operation of said pump for recirculating fluid between said pump and heat sink block when the video light source is operating;
- and a liquid reservoir for use in maintaining a fluid level within the recirculating fluid;
- wherein heat from an LCOS, LPD, LED or the like projector light source secured to said heat sink block is transferred to the fluid and dissipated during the recirculation of the fluid.
