a second conduit provided in parallel with the first conduit;
a first aperture provided in the first conduit for supplying the refrigerant to one of the heat receivers;
a first blocking object provided below the first aperture for blocking the first conduit;
a first communication opening provided above the first aperture and communicating the first conduit and the second conduit;
a second communication opening provided below the first blocking object and communicating the first conduit and the second conduit; and
a second blocking object provided below the second communication opening for blocking the second conduit.

2. A refrigerant supply device comprising:
a plurality of refrigerant supply devices according to claim 1 in a series.

3. The refrigerant supply device according to claim 1 ,
further comprising lids for respectively blocking the first conduit and the second conduit at ends closer to a lowest tier of the first conduit and the second conduit.

4. A cooling device comprising:
a refrigerant supply device according to claim 1 ,
a heat receiver connected with the first aperture, and
a gas phase tube connected with the heat receiver for exhausting
the gas phase refrigerant from the heat receiver.

5. A cooling system comprising:
a cooling device according to claim 4 and
a radiator interposed between the gas phase tube and the refrigerant supply device for releasing heat of the refrigerant.

6. The cooling system according to claim 5 ,
wherein the refrigerant used in the cooling system is an insulating material.

7. A method of supplying refrigerant using a refrigerant supply device according to claim 1 , comprising:
storing the refrigerant in the first conduit by the first blocking object;
supplying the refrigerant through the first aperture to one of the heat receivers;
allowing the refrigerant to overflow through the first communication opening to the second conduit;
keeping the refrigerant in the second conduit by the second blocking object; and
allowing the refrigerant to overflow through the second communication opening to the first conduit.

8. A method of supplying refrigerant, comprising:
conducting the method of supplying refrigerant according to claim 7 in a series to supply the refrigerant evenly among a plurality of the heat receivers.

9. A method of controlling the cooling system according to claim 5 , comprising:
supplying liquid phase refrigerant from the refrigerant supply device to the heat receivers;
bringing the refrigerant to a boil by giving the heat receivers heat from an object to be cooled;
returning the evaporated refrigerant through the gas phase tube to the radiator;
liquefying the refrigerant by releasing heat of the refrigerant with the radiator; and
returning the refrigerant to the refrigerant supply device.

10. The refrigerant supply device according to claim 2 , further comprising lids for respectively blocking the first conduit and the second conduit at ends closer to a lowest tier of the first conduit and the second conduit.

11. A cooling device comprising:
a refrigerant supply device according to claim 2 ,
a heat receiver connected with the first aperture, and

storing the refrigerant in the first conduit by the first blocking object;
supplying the refrigerant through the first aperture to one of the heat receivers;
allowing the refrigerant to overflow through the first communication opening to the second conduit;
keeping the refrigerant in the second conduit by the second blocking object; and
allowing the refrigerant to overflow through the second communication opening to the first conduit.

14. A method of supplying refrigerant using a refrigerant supply device according to claim 3 , comprising:
storing the refrigerant in the first conduit by the first blocking object;
supplying the refrigerant through the first aperture to one of the heat receivers;
allowing the refrigerant to overflow through the first communication opening to the second conduit;
keeping the refrigerant in the second conduit by the second blocking object; and
allowing the refrigerant to overflow through the second communication opening to the first conduit.

15. A method of controlling the cooling system according to claim 6 , comprising:
supplying liquid phase refrigerant from the refrigerant supply device to the heat receivers;
bringing the refrigerant to a boil by giving the heat receivers heat from an object to be cooled;
returning the evaporated refrigerant through the gas phase tube to the radiator;
liquefying the refrigerant by releasing heat of the refrigerant with the radiator; and
returning the refrigerant to the refrigerant supply device.
