Cooling System And Cooling Method For Cooling Components Of A Power Electronics

Cooling system and cooling method for cooling components of a power electronics The invention relates to a cooling system for cooling components (10) of power electronics installed on board an aircraft, in particular a passenger aircraft, comprising a cooling device (30) which is to be coupled in a heat-transmitting and planar manner to the components of the power electronics, and which cooling device (30) comprises at least two heat sinks (32, 34, 36, 38, 39, 50) fluidly isolated from one another, the cooling system further comprising at least two cooling circuits each including a cooling fluid source, wherein the at least two heat sinks of the cooling device (30) can be separately supplied with cooling fluids from different cooling fluid sources, and wherein the cooling system is configured such that no phase transition of the cooling fluids within the cooling circuits occurs, during operation of the cooling system. The invention also relates to a method for cooling components of power electronics.
