Technical Field

The invention relates to a liquid cooling system, in particular to an offshore liquid cooling system based on a wind driven generator and a hydrogen-oxygen fuel cell.

Background

An offshore wind turbine is an electric device which converts wind energy into mechanical work, and the mechanical work drives a rotor to rotate so as to finally output alternating current. In the operation process of the offshore wind turbine, some electronic devices of the offshore wind turbine generate a large amount of heat, such as IGBT modules, and the like, so that cooling equipment is required to cool the electronic devices to ensure the normal operation of the heat generating devices. At present, electronic devices of offshore wind driven generators are generally cooled by a liquid cooling system, charged ions often exist in cooling liquid in the liquid cooling system for power electronic devices, and if the number of the charged ions in the cooling liquid is large and the resistivity is low, a circuit short circuit is easy to form, so that the normal operation of the devices is influenced.

In order to solve this problem, a resin deionization apparatus is generally installed in a liquid cooling system for power electronics to remove charged ions in the cooling liquid and maintain the cooling liquid in a desired resistivity range. In order to ensure the effectiveness of the resin deionization device, the resin of the resin deionization device needs to be replaced frequently, and the offshore wind turbine generator is often located in a remote sea area, so that the cost for replacing the resin of the resin deionization device frequently is extremely high, the operation is inconvenient, and the cooling system needs to be shut down frequently when the resin of the resin deionization device is replaced frequently, and the normal operation of the cooling system is influenced.

On the other hand, although the wind power utilization rate is high, the wind abandoning rate of the wind power is high, and especially the wind abandoning rate of the offshore wind driven generator is very large at night, which causes energy waste.
