Cooling waterway system and offshore wind power converter

Abstract

The invention discloses a cooling water path system which comprises a gas pressure stabilizing device, a heating device and a heat exchanger, the gas pressure stabilizing device comprises a water tank, a water pump connected with the water tank and a gas supplementing pump, the water tank is provided with a gas inlet, the gas supplementing pump is arranged on the gas inlet, and the heat exchanger is arranged on the gas inlet. The heating device and the heat exchanger are connected through a first pipeline, the first pipeline is further provided with a water pump used for driving the first pipeline to conduct water cooling flowing, and the water tank is connected to the first pipeline through a second pipeline. The cooling water path system can achieve automatic air supply and exhaust to adjust the system pressure, is high in reliability and long in service life, solves the problem that an expansion tank needs frequent manual air supply, solves the problem that a pressure stabilizing device needs to be installed at the highest point of the system, and enables the whole water cooling system to be more compact and flexible in structural arrangement.

Description

technical field [0001] The invention relates to the technical field of high-power power electronic equipment, in particular to a cooling waterway system and an offshore wind power converter. Background technique [0002] In the field of high-power power electronic equipment, such as wind power and variable frequency drive, with the increase of equipment power density, heat dissipation has become a very difficult problem. For high-power power electronic equipment, the simple air cooling technology can no longer meet the cooling requirements, and liquid cooling is a more effective method than air cooling. Liquid cooling continuously provides cooling medium with stable pressure and flow rate to the system through the circulating cooling system. Commonly used cooling systems are divided into open systems and closed systems. Open cooling systems have problems such as scaling, corrosion, and large water consumption. Therefore, closed circulation cooling systems have become the de...
