Method for cooling components subjected to high temperatures
View Patent ↗Heat is transferred away from the rollers and base of a printer heater by introducing chilled water into the rollers and the base. The paper upon which print has been applied remains at an elevated temperature so that the drying of the print is not delayed. A conventional roller is modified by having an annular cavity formed in its interior and providing fluid communication between the cavity and a chiller. A conventional base is modified by the addition of a serpentine passageway formed in its interior and providing fluid communication between the passageway and the chiller. Cold water provided by the chiller to the roller prevents breaking down of oil in the bearings of the roller. Cold water provided by the chiller to the base carries the heat from the base, increasing the safety of the workplace and extending the working lifetime of the base and its related parts.
1. A method for cooling components associated with a heater for a high-speed printer, comprising the steps of:
providing a flat base having a top surface, a bottom surface, and a straight configuration;
rotatably mounting a first roller to said base at a first end thereof and a second roller to said base at a second end thereof;
wrapping a conveyer means around said base so that said first and second rollers define a path of travel for said conveyor means;
positioning a heater in closely spaced relation to said top surface of said base;
positioning said heater so that said heater is in heat-transferring relation to said conveyor means;
forming at least one internal passageway in said base, said at least one internal passageway having an inlet and an outlet;
providing fluid communication between a source of chilled water and said at least one internal passageway;
connecting an outlet of said source of chilled water to said inlet of said at least one internal passageway;
connecting said outlet of said at least one internal passageway to an inlet of said source of chilled water; and
circulating said chilled water through said at least one internal passageway when said heater is operating so that said base is cooled.
