Abstract

Disclosed herein is a cooling system for two-dimensional array power converters. The cooling system includes: a plurality of power converters 110 arranged in two-dimension; a compressor 130 configured to generate compressed air; vortex tubes 150 each installed in the respective power converters, the vortex tubes configured to generate low-temperature air based on compressed air from the compressor; valves 140 installed between the compressor and the vortex tubes; temperature sensors 120 each installed in the respective power converters to measure temperature inside the power converters; and a controller 160 configured to determine whether to supply the low-temperature air into the power converters by using the vortex tubes, based on the temperature measured by the temperature sensors, and to control the valves depending on a result of the determination.

Description

technical field [0001] The present disclosure relates to a cooling system, and more particularly, to a cooling system for a two-dimensional array power converter capable of stably cooling power converters arranged in two dimensions by employing a vortex tube. Background technique [0002] When power converters are used in industrial sites, devices such as inverters for motor drives, solar inverters, energy storage systems (ESS), etc. generate heat when they are driven. [0003] Since heat generated when a power converter is driven causes performance degradation, shortened life, interruption, etc. of the device, there is a continuous need to develop a system for effectively cooling the device. [0004] Therefore, various cooling devices for cooling power converters have been proposed. Cooling devices can be classified into air-blown and water-cooled. [0005] The blown type is a method of forcibly dissipating heat generated by a power converter using a fan, which is also ca...
