Claims
- 1. In a method for cooling a substance to be cooled, by using heat transfer means, the improvement comprising the use of a heat conducting body being in a two-phase state of liquid and solid uniformly throughout the body at a temperature of said substance and disposed between said substance and the heat transfer means, said heat conducting body having a coefficient of viscosity greater then 3,000 centipoise at the operating temperature of said substance.
- 2. A method according to claim 1, wherein said heat conducting body consists essentially of 50-94 weight % indium and 50-6 weight % gallium.
- 3. A method according to claim 1, wherein said heat conducting body consists essentially of 20-60 weight % tin and 80-40 weight % gallium.
- 4. A method of cooling a heat generating substance, used in a space vehicle, by transferring heat from the heat generating substance to another, fixed substance having high heat conductivity, said method comprising the steps of:
- using a fixed mechanical joint for mechanically jointing the heat generating substance and the fixed substance; and
- using a heat conducting body, which is a mixture comprising 50 to 94 weight percent indium and the balance gallium which is in a state of a two-phase field of liquid and solid uniformly throughout the body, in the fixed mechanical joint so as to be disposed substantially between the heat generating substance and the fixed substance.
- 5. A method according to claim 4, wherein said heat conducting body has coefficient of viscosity greater than 3,000 centipoise at a temperature less than 40.degree. C. in a vacuum.
- 6. A method according to claim 4, wherein said heat conducting body has a vapor pressure less than 10.sup.-32 Torr in a perfect vacuum.
- 7. A method of cooling a heat generating substance, used in space, by transferring heat from the heat generating substance to another fixed substance having high heat conductivity, said method comprising the steps of:
- using a fixed mechanical joint for mechanically jointing the heat generating substance and the fixed substance; and
- using a heat conducting body, which is a mixture comprising 20 to 60 weight percent tin and the balance gallium which is in a state of a two-phase field of liquid and solid uniformly throughout the body, in the fixed mechanical joint so as to be disposed substantially between the heat generating substance and the fixed substance.
- 8. A method according to claim 7, wherein said heat conducting body has a coefficient of viscosity greater than 3,000 centipoise at a temperature less than 40.degree. C. in a vacuum circumstances.
- 9. A method according to claim 7, wherein said heat conducting body has a vapor pressure less than 10.sup.-36 Torr in a perfect vacuum.
- 10. A method of cooling a heat generating substance, used in a space vehicle, by transferring heat from the heat generating substance to a rotatable substance, having high heat conductivity, said method comprising the steps of:
- using a rotatable mechanical joint for mechanically jointing the heat generating substance and the rotatable substance; and
- using a heat conducting body, which is a mixture comprising 50 to 94 percent indium and the balance gallium and which is in a state of two-phase field of liquid and solid uniformly throughout the body, in the rotatable mechanical joints so as to be disposed substantially between the heat generating substance and the rotatable substance.
- 11. A method according to claim 10, wherein said heat conducting body has coefficient or viscosity greater than 3,000 centipoise at a temperature less than 40.degree. C. in a vacuum.
- 12. A method according to claim 10, wherein said heat conducting body has a vapor pressure less than 10.sup.-32 Torr in a perfect vacuum.
- 13. A method of cooling a heat generating substance, used in a space vehicle, by transferring heat from the heat generating substance to a rotatable fixed substance, having high heat conductivity, said method comprising the steps of:
- using a rotatable mechanical joint for mechanically jointing the heat generating substance and the rotatable substance; and
- using a heat conducting body, being a mixture comprising 20 to 60 weight percent tin and the balance gallium and which is in a state of a two-phase field of liquid and solid uniformly throughout the body, in the rotatable mechanical joint so as to be disposed substantially between the heat generating substance and the rotatable substance.
- 14. A method according to claim 13, wherein said heat conducting body has a coefficient of viscosity greater than 3,000 centipoise at a temperature less than 40.degree. C. in a vacuum.
- 15. A method according to claim 13, wherein said heat conducting body has a vapor pressure less than 10.sup.-36 Torr in a perfect vacuum.
