US 2006/0232935 A1 · Cooling pad for laptop computer

Abstract

A self contained laptop computer cooling pad that does not require any electrical power to operate and will effectively and efficiently reduce the operating temperature of the computer and reduce the heat being transferred into the user's lap. The cooling pad contains a phase-changing compound such as sodium sulfate decahydrate, sodium carbonate decahydrate, disodium phosphate dodecahydrate or sodium thiosulfate pentahydrate, and may be made of a soft, flexible material that will contain the phase-changing compound and prevent excess shifting within the cooling pad. The cooling pad is placed under the laptop computer when operating the computer to effectively transfer heat away from the computer by conduction and prevent passage onto the user. The cooling pad may be in the form of a sleeve to additionally provide padded storage for the computer when not in use.

A separate external cooling pad for a conventional laptop computer having a bottom surface through which heat is dissipated, the cooling pad comprising:

a generally planar rectangular-shaped flexible housing of a size corresponding to the bottom surface of the laptop computer;
the housing having a top portion divided into a plurality of approximately equal sized pockets;
phase change material disposed inside the pockets;
whereby the top portion of the cooling pad may be placed between the bottom surface of the laptop computer and the user's lap, to absorb the heat from the computer and preventing the heat from reaching the user.
