Abstract
A cooling system for apparatus powered by electricity, that generates a substantial amount of heat during operation, and the heat must be dissipated to avoid failure of electrical and/or electronic components, such as semiconductor devices and integrated circuits, comprising the electrical apparatus. The cooling system employs liquid ice impinged on a heat sink thermally coupled with electrical apparatus. The attendant phase changes of the liquid ice first to water and then to steam remove a substantial amount of waste heat to prevent failure of the electrical apparatus.
Claims18
A cooling system for thermally conducting and removing high heat flux waste heat from electrical apparatus, comprising:
- liquid ice at a predetermined pressure;
- a heat transfer plate having a first side thermally coupled with the electrical apparatus, the heat transfer plate being constructed from a thermally conductive material with high tensile strength to enable efficient heat transfer by thermal conduction;
- a circulation subsystem that contains the liquid ice, the heat transfer plate comprising a structural component of the circulation subsystem;
- and
- means for impinging the liquid ice on a second side of the heat transfer plate opposite the side on which the electronic apparatus is disposed.
