Abstract

The utility model relates to the technical field of energy storage converters, and discloses a liquid cooling energy storage converter, which is characterized in that an inversion power device, a power inductor and a heat exchanger are arranged on a liquid cooling plate in a coplanar manner to form a single-layer planar design, and a first fan, a second fan, a third fan and a fourth fan form a closed circulating heat dissipation loop. Therefore, the height of the module is greatly reduced, the occupation of the height space in the container can be obviously reduced, and the heat dissipation requirement can be met; meanwhile, the two liquid cooling energy storage converters can be stacked up and down in the container for installation, wire outgoing of the modules is more convenient, system layout is more reasonable and compact, system power density and integration degree are improved, wiring and assembling processes are simplified, and overall performance and reliability of the energy storage alternating current and direct current all-in-one machine are enhanced.
