Cooling system for tanks
A tank assembly has heat-generating equipment contained therein. The tank assembly includes a heat pipe having an opening, wherein an interior of the heat pipe contains a liquid and a gas. The tank assembly further includes a tank fixed to the heat pipe and sealing the opening of the heat pipe. The tank houses at least one of a disconnector switch and a circuit breaker operatively connected to the disconnector switch. The sealing of the opening of the heat pipe prevents the liquid and the gas from entering the tank. The heat pipe extends beyond a side of the tank, and has a cooling portion.
1. A tank assembly having heat-generating equipment contained therein, comprising: a thermal siphon having an opening, wherein the thermal siphon contains a liquid and a gas, and wherein the thermal siphon has a cooling portion; and a first closed tank and a second closed tank, wherein the first closed tank or the second closed tank is fixed to the thermal siphon such that a side of the first closed tank or the second closed tank seals the opening of the thermal siphon, wherein the first closed tank houses a disconnector switch, and wherein the second closed tank houses a circuit breaker operatively connected to the disconnector switch.
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 the first or second closed tank are welded or brazed together.
4. The tank assembly of claim 1 , wherein the thermal siphon and the first or second closed 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 thermal siphon having an opening, wherein an interior of the thermal siphon contains a liquid and a gas; and a tank fixed to the thermal siphon and sealing the opening of the thermal siphon, wherein the tank houses at least one of a disconnector switch and a circuit breaker, wherein the sealing of the opening of the thermal siphon prevents the liquid and the gas from entering the tank, wherein the thermal siphon extends beyond a side of the tank, and wherein the thermal siphon has a cooling portion.
8. The tank assembly of claim 7 , further including a plurality of thermal siphons located adjacent to the tank.
9. The tank assembly of claim 7 , further including a fin stack fixed to the thermal siphon, wherein the fin stack includes fins extending from the thermal siphon.
10. The tank assembly of claim 9 , wherein the fin stack is configured to dissipate heat to an airflow passing between fins of the fin stack.
11. The tank assembly of claim 7 , further comprising a second tank, wherein the second tank houses at least one of the disconnector switch and the circuit breaker.
12. A tank assembly having heat-generating equipment contained therein, comprising: a thermal siphon having an opening, wherein an interior of the thermal siphon contains a liquid and a gas; and a first tank fixed to the thermal siphon and sealing the opening of the thermal siphon, wherein the first tank houses at least one of a disconnector switch and a circuit breaker, wherein the sealing of the opening of the thermal siphon prevents the liquid and the gas from entering the first tank, wherein the thermal siphon has a cooling portion that includes electrically insulated walls.
13. The tank assembly of claim 12 , further comprising a fin stack fixed to the cooling portion of the thermal siphon.
14. The tank assembly of claim 12 , wherein the first tank includes a flange bolted to the thermal siphon.
15. The tank assembly of claim 12 , wherein the thermal siphon is embedded in a plate that is fixed to the first tank.
16. The tank assembly of claim 15 , further comprising a second thermal siphon embedded in the plate.
17. The tank assembly of claim 12 , wherein the liquid is a dielectric liquid.
18. The tank assembly of claim 12 , wherein the first tank houses a disconnector switch.
19. The tank assembly of claim 12 , wherein the first tank houses a disconnector switch.
20. The tank assembly of claim 12 , further comprising 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.
