Abstract
A system for cooling a slurry compound used during polishing and grinding is disclosed. In one embodiment, the system includes a cooling module, such as a refrigeration unit, connected to a heat-transfer device, such as a metal coil. The cooling module cools the heat-transfer device. The heat-transfer device cools the slurry compound.
Claims21
An apparatus comprising:
- a container to hold a surface polishing slurry compound that is to be circulated;
- a heat-transfer device captured in thermal proximity to the container to cool the surface polishing slurry compound when the surface polishing slurry compound circulates to the container, and
- a cooling module connected to the heat-transfer device, the cooling module to cool the heat-transfer device as the heat-transfer device cools the surface polishing slurry compound.
An apparatus, comprising:
- a hand-held surface polishing tool;
- a container to hold a surface polishing slurry compound, the surface polishing slurry compound to be circulated from the container through the hand-held surface polishing tool and back to the container;
- a heat-transfer device captured in thermal proximity to the container to cool the surface polishing slurry compound when the surface polishing slurry compound circulates back to the container;
- a cooling module connected to a heat-transfer device to cool the heat-transfer device, the cooling module including coolant to be circulated between the cooling module and the heat-transfer device through a circulating line;
- and
- a portable framework to hold the container, the heat-transfer device, and the cooling module.

A method comprising:
- transporting a surface polishing slurry compound, to be circulated, from a portable container, to a surface polishing tool;
- polishing a surface with the surface polishing tool utilizing the surface polishing slurry compound to cool the surface during polishing, the surface polishing slurry compound thus becoming heated;
- transporting the heated surface polishing slurry compound out of the surface polishing tool to the portable container;
- monitoring the temperature of the surface polishing slurry compound to determine if the temperature of the surface polishing slurry compound has reached a predetermined level;
- and
- cooling the polishing slurry compound when the heated polishing slurry compound is transported to the portable container by capturing heat from the slurry compound via a heat-transfer device, captured in thermal proximity to the surface polishing slurry compound.
