Abstract
An apparatus and a method for cooling a digital mirror device are disclosed. For example, the apparatus includes a digital mirror device (DMD), a thermal pad, wherein a first side of the thermal pad is coupled to a bottom of a housing of the DMD and a cooling block coupled to a second side of the thermal pad that is opposite the first side. The cooling block includes a plate that includes a plurality of openings that generates a liquid jet of a liquid that is forced through the plurality of openings towards a side of the cooling block coupled to the thermal pad.
Claims13
A method for cooling a digital mirror device (DMD), comprising:
- measuring a temperature of the DMD;
- determining that the temperature of the DMD is above a threshold;
- and
- providing a liquid through a cooling loop to a cooling block of the DMD, the cooling block comprising a plate having a plurality of openings that generates a liquid jet of the liquid that is forced through the plurality of openings towards a side of the cooling block coupled to the DMD, wherein the liquid is delivered through the plurality of openings at 0.3 gallons per minute (qpm) to 0.5 gpm at 19 pounds per square inch (psi) to 50 psi, wherein the plurality of openings has a diameter of 0.25 millimeters (mm) to 0.5mm.
A laser imaging module (LIM), comprising:
- a digital mirror device (DMD);
- a thermal pad, wherein a first side of the thermal pad is coupled to a bottom of a housing of the DMD;
- a cooling loop that delivers a liquid;
- and
- a cooling block coupled to the thermal pad and the cooling loop, wherein the cooling block comprises:
- a plate comprising a plurality of openings, wherein a diameter of each one of the plurality of openings is 0.25 millimeters (mm) to 0.5 mm to deliver 0.3 gallons per minute (gpm) to 0.5 gpm of the liquid at 19 pounds per square inch (psi) to 50 psi through the plurality of openings towards a side of the cooling block coupled to the thermal pad.
