Inverter heat dissipation device for photovoltaic power generation

Abstract

The invention relates to the technical field of electrical equipment, and discloses an inverter heat dissipation device for photovoltaic power generation. The inverter heat dissipation device comprises a heat dissipation outer shell, wherein an inverter controller is arranged at the bottom part of the interior of the heat dissipation outer shell, heat dissipation blocks are arranged on the front side and the rear side of the inverter controller, heat pipes are evenly arranged in the heat dissipation blocks, temperature sensing pipes are arranged on the heat pipes of the heat dissipation blocksat intervals, each temperature sensing pipe comprises a pipe body, a bimetallic strip is arranged in each pipe body, a sealing ring is arranged on the upper portion of each pipe body, a front bevel gear at the upper end of each bimetallic strip is in meshed connection with a dial, a rear bevel gear at the upper end of each bimetallic strip is in meshed connection with a worm, and the right side of each worm is in meshed connection with an adjusting gear. According to the inverter heat dissipation device for photovoltaic power generation, when the temperature exceeds an early warning value, aslip sheet connector deflects to the resistor disc insulation section, a heat dissipation circuit is disconnected, a protector controls a disconnection connecting rod to reset rightwards and disconnect main power supply of an inverter circuit, an inverter controller can be prevented from being burnt, and the service life of the inverter circuit is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an inverter cooling device for photovoltaic power generation. Background technique [0002] With the continuous innovation of photovoltaic cell technology, the latest monocrystalline silicon solar photovoltaic cells have not only greatly improved their efficiency, but also lowered the cost of power generation of photovoltaic power plants below that of traditional thermal power plants, becoming the main force of energy-saving and environmentally friendly new energy power generation. At the same time, with the packaging technology The life of the photovoltaic module has also been greatly improved, and the design life of the inverter originally designed for matching with the photovoltaic module has not matched. The life of electrical components is shorter than that of photovoltaic components, and the inverter has to be replaced, which will increase the cost. Contents ...
