Abstract:
1. A cooling apparatus comprising: a shell having an interior hermetically storing water in a liquid form, and a port communicating with the interior of the shell and located above a surface of the water stored in the shell; a heat exchanging structure adapted to receive a substance to cool down, the heat exchanging structure being a chamber that is formed as a recessed region in the shell and is accessible from outside the shell for placement of the substance to cool down, the heat exchanging structure having one or more heat transfer walls, each of the heat transfer walls has a first surface in contact with the water stored in the shell and a second surface for contacting with the substance to cool down, and the chamber being mounted with a lid operable to upwardly close and open the chamber, the lid when opened exposing an interior of the chamber while the water remains hermetically sealed in the shell; and a vacuum pump connected with the port, the vacuum pump being activated to create a partial vacuum on the surface of the water in the liquid form, which causes a decrease in temperature of the water stored in the shell to a desirable cooling temperature, the water at the desirable cooling temperature thereby acting as a coolant for the substance received in the heat exchanging structure.
