Abstract
A cleaning apparatus having a container for holding a quantity of cleaning agent, which is vaporized and condensed to form an upper vapor layer. Essentially, the container is divided into a lower chamber, for holding the cleaning agent, and an upper chamber for containing the vapors. One or more heat pumps are adapted to establish a relatively low temperature in the upper region to condense the vapors released by the lower heating process. Multiple high thermally conductive shunting devices are coupled between the high temperature end of the heat pumps and the bottom portion of the container to transfer extracted heat from the upper portion to the lower portion, to augment the vaporization process.
