Abstract

A heat sink is disclosed which consists of a permanently sealed container which contains LiClO₄.3R₂ O, NH₄ Al(SO₄)₂.12R₂ O or (COOH)₂.2R₂ O, where R is hydrogen or deuterium. The heat sink can be used in combination with a radiator to protect electronic circuitry or other equipment from temporary overheating.

Claims

1. A method of storing heat comprising repeatedly transferring heat to a heat sink which comprises a compound selected from the group consisting of LiClO₄.3R₂ O and (COOH)₂.2R₂ O, where 100% of each R is independently selected from 0 to 100% hydrogen and 0 to 100% deuterium.

2. A method according to claim 1 wherein said compound is LiClO₄.3H₂ O.

3. A method according to claim 1 wherein said compound is (COOH)₂.2H₂ O.

4. A method according to claim 1 wherein said compound is (COOH)₂.2D₂ O.

5. A method of protecting electronic circuitry from temporary overheating comprising (1) transferring heat from said circuit to a heat sink comprising a compound selected from the group consisting of LiClO4.3R₂ O and (COOH)₂ .2R₂ O, where 100% of each R is independently selected from 0 to 100% hydrogen and 0 to 100% deuterium;

and (2) radiating said heat away from said heat sink.

6. A method according to claim 5 wherein said compound is LiClO₄.3H₂ O.

7. A method according to claim 5 wherein said compound is (COOH)₂.2H₂ O.

8. A method according to claim 5 wherein said compound is (COOH)₂.2D₂ O.
