摘要:
There is presented an arrangement for cooling components of a subsea electric system. The arrangement comprises a tank filled with a dielectric fluid. The arrangement comprises at least one electric component located in the tank. The arrangement comprises a first heat exchanger located outside the tank and in fluid contact with the tank, and during operation arranged to be in thermal contact with sea water. The arrangement comprises a pump arranged to force a flow of the dielectric fluid through the first heat exchanger. The arrangement is configured such that during operation the dielectric fluid receives heat from the at least one electric component, flows from the tank into the first heat exchanger, flows through the first heat exchanger to transfer heat to the sea water, and flows back from the first heat exchanger into the tank through the pump. The flow of the dielectric fluid in the tank and around the at least one electric component is by natural convection.

摘要:
A cooling system for cooling of a heat generating electrical component, in particular to reduce the likelihood of overheating of electrical components or chemical breakdown of coolant fluid. The cooling system has a coolant liquid to absorb excess energy from the heat generating electrical component, the coolant liquid having an energy input threshold above which chemical breakdown of the coolant liquid occurs. A cooling module defines a volume containing the coolant liquid, wherein the heat generating electrical component is mounted within the volume and immersed in the coolant liquid. A power input is arranged to supply power into the cooling module to the heat generating electrical component, and a power regulator is provided external to the volume of the cooling module and connected to the power input so as to regulate the power supplied into the cooling module. Cooling systems are also described having coolant liquid comprising dissolved oxygen, having at least one element arranged within the volume comprising aluminium and/or aluminium oxide, and/or having a sealed volume with at least one seal which opens at a predetermined pressure or temperature corresponding to a temperature below the temperature at which the coolant liquid breaks down.

The present invention relates to the cooling of power electric and/or electronic components, in particular to a heat exchanger system (200) for moving heat from a heat source (120) comprising at least one of an electric and an electronic component (120). The heat exchanger system (200) comprises a first cooling circuit (210) that is formed as a loop-type thermo siphon comprising a first coolant with at least partially changes phases between the liquid state and a vaporous state in an operating state of the first cooling circuit (210) when heated up above a vaporization point of the first coolant. The first cooling circuit (210) has a first interface (212) for receiving a thermal load from the heat source (120) that is thermally connected to the first interface (212) and has a second interface (214) for releasing a major portion of said thermal load. The first interface (212) acts as a first evaporator (131) and the second interface (214) acts as a first condenser (133) in an operating state of the first cooling circuit (210). The heat exchanger system (200) further comprises a second cooling circuit (212) that is formed as a loop-type thermo siphon comprising a second coolant which at least partially changes phases between a liquid state and a vapor state, an operating state of the second cooling circuit (220) when heated up above a vaporization point of the second coolant. The second cooling circuit (212) has a third interface (216) that is thermally connected to the second interface (214). The second cooling circuit (220) has a fourth interface (218) for releasing the major portion of said thermal load taken up at the third interface (216). The third interface (216) acts as a second evaporator (212) and the fourth interface (218) acts as a second condenser (222) in an operating state of the second cooling circuit (212).
