Cooling system for tanks

1. A tank assembly having heat-generating equipment contained therein, comprising:

a tank having an opening,

wherein the tank includes a first tank and a second tank,

wherein the first tank houses a disconnector switch, and

wherein the second tank houses a circuit breaker operatively connected to the disconnector switch; and

a thermal siphon fixed to the tank adjacent to the opening,

wherein the thermal siphon contains a liquid and a gas, and

wherein the thermal siphon has a cooling portion.

2. The tank assembly of claim 1 , wherein the tank assembly is part of a gas-insulated medium voltage switchgear assembly.

3. The tank assembly of claim 1 , wherein the thermal siphon and tank are welded or brazed together.

4. The tank assembly of claim 1 , wherein the thermal siphon and tank are bolted together, and sealed with a gasket.

5. The tank assembly of claim 1 , wherein the thermal siphon forms a closed loop.

6. The tank assembly of claim 5 , further including at least one hose attached to the cooling portion.

7. A tank assembly having heat-generating equipment contained therein, comprising:

a tank having an opening;

wherein the tank houses a disconnector switch and a circuit breaker operatively connected to the disconnector switch;

a heat pipe having a side fixed to the tank and sealing the opening,

wherein an interior of the heat pipe contains a liquid and a gas,

wherein the sealing of the opening of the tank prevents the liquid and the gas from entering the tank,

wherein the heat pipe extends beyond a side of the tank, and

wherein the heat pipe has a cooling portion.

8. The tank assembly of claim 7 , further including a plurality of heat pipes located adjacent to the tank.

9. The tank assembly of claim 7 , further including a fin stack fixed to the heat pipe, wherein the fin stack includes fins extending from the heat pipe.

10. The tank assembly of claim 9 , wherein the fin stack is configured to dissipate heat to an airflow passing between the fins.

11. The tank assembly of claim 7 , wherein the tank includes a first tank and a second tank, wherein the first tank houses a disconnector switch and wherein the second tank houses a circuit breaker operatively connected to the disconnector switch.

12. A tank assembly having heat-generating equipment contained therein, comprising:

a tank having an opening, wherein the tank houses at least one of a disconnector switch and a circuit breaker; and

a thermal siphon having a side fixed to the tank and sealing the opening,

wherein an interior of the thermal siphon contains a liquid and a gas,

wherein the sealing of the opening of the tank prevents the liquid and the gas from entering the tank, and

wherein the thermal siphon has a cooling portion.

13. The tank assembly of claim 12 , further comprising a fin stack fixed to a portion of the thermal siphon, wherein the fin stack includes at least one fin extending outwardly from the thermal siphon.

14. The tank assembly of claim 12 , wherein the tank includes a first flange and the thermal siphon includes a second flange, and wherein the first flange is bolted to the second flange.

15. The tank assembly of claim 14 , further comprising a gasket disposed between the first flange and the second flange.

16. The tank assembly of claim 12 , wherein the tank houses a disconnector switch.

17. The tank assembly of claim 12 , wherein the tank houses a circuit breaker.

18. The tank assembly of claim 12 , wherein the thermal siphon has a main body containing the liquid, and wherein the cooling portion extends away from the main body.

19. The tank assembly of claim 12 , wherein the liquid is a dielectric liquid, and wherein the thermal siphon includes walls contains an insulating material.

20. The tank assembly of claim 12 , wherein the tank includes a first tank and a second tank, wherein the first tank houses a disconnector switch and wherein the second tank houses a circuit breaker operatively connected to the disconnector switch.
