1. A cooling system for cooling a heat generating component, the cooling system comprising:
a main cooling arrangement thermally coupled to the heat generating component, and configured for collecting thermal energy of the heat generating component via a main heat transfer fluid; and
a backup cooling arrangement thermally coupled to the main cooling arrangement, the backup cooling arrangement comprising:
at least one fluid path configured for conducting a backup heat transfer fluid;
a thermal fuse disposed within at least a portion of the at least one fluid path, the thermal fuse changing from a solid state to a melted state and selectively enabling a flow of the backup heat transfer fluid in the at least one fluid path of the backup cooling arrangement in response to its temperature being above a temperature threshold, the backup heat transfer fluid being configured to, upon flowing in the at least one fluid path, collect thermal energy from the main cooling arrangement.
