Abstract
The utility model discloses a modular inversion core structure for a photovoltaic grid-connected inversion apparatus. The modular inversion core structure comprises a cabinet, in which there sets of die boxes are fixedly arranged via a support. Each die box comprises a bottom plate. A heat radiator is fixed at one side of the bottom plate, and power units are uniformly disposed at the other side of the bottom plate and on the heat radiator. One side of the bottom plate where the power units are located is provided with a series of heat-radiating auxiliary holes. A fan is arranged right below the heat radiator. An air duct is formed between the heat radiator and the fan. The modular inversion core structure of the utility model, which has a simple structure and is convenient to manufacture, install, debug and maintain, can effectively solve the cooling problem of power components, which therefore can work safely and stably for a long period of time.
