Abstract

The invention discloses a photovoltaic inverter which comprises a cabinet body, a boosting module and an inversion module, wherein the boosting module and the inversion module are arranged in the cabinet body, and cooling fins are arranged on the boosting module and the inversion module. The photovoltaic inverter further comprises a fan which is arranged in the cabinet body. An air inlet and an air outlet are formed in the cabinet, and the fan enables gas to enter the cabinet body and to pass by the air inlet, the cooling fins and the air outlet in sequence. When the photovoltaic inverter works, modules with a larger heating amount are the boosting module and the inversion module, the heat generated by the boosting module and the inversion module can be transmitted to the cooling fins, the fan enables the gas to enter the cabinet body through the air inlet, to pass by the cooling fins and to flow out of the cabinet body through the air outlet. Each cooling fin can dissipate heat by itself, when the gas passes by the cooling fins, heat exchanging occurs between the cooling fins and the flowing gas, and the heat can be transmitted out of the cabinet body along with the flowing gas. Therefore, heat dissipating capacity of the cooling fins is greatly improved, a heat-dissipating effect is provided, and the heat-dissipating requirement of large-power photovoltaic inverters can be met.

Description

Technical field [0001] The present invention relates to the field of photovoltaic technology, in particular to a photovoltaic inverter. Background technique [0002] Photovoltaic power generation system is a power generation system that uses solar cells to directly convert solar energy into electrical energy. It is characterized by high reliability, long service life, no environmental pollution, independent power generation and grid-connected operation. [0003] The main components of the photovoltaic power generation system include the solar cell array, battery pack, charge and discharge controller, and inverter. In the presence of light, the solar cell array absorbs light energy and converts the light energy into electric energy; the battery pack stores the electric energy converted by the solar cell array; the charge and discharge controller can prevent the battery pack from overcharging or overdischarging; The device is responsible for converting direct current into alternatin...
