photovoltaic inverter

The photovoltaic industry and 5G communication industry are developing more and more rapidly, and the energy consumption of products is also increasing. In addition to optimizing the product structure, the heat dissipation performance of the die-cast photovoltaic inverter shell also requires higher and higher thermal conductivity of the die-cast aluminum alloy.

Characteristics of photovoltaic inverter

The photovoltaic inverter can also be called a grid-connected string inverter. The inverter solar inverter can only generate electricity during the day and will also be affected by factors such as weather. Therefore, it is generally necessary to use it with an energy storage inverter to store excess electricity and release the stored electricity during peak load to reduce the pressure on the power grid.

With the rapid development of the photovoltaic power generation industry at home and abroad, the annual average growth rate of solar energy inverter is 10-50%. The current mainstream trend is to take the integration of photovoltaic storage as the main development direction, effectively solving some of the disadvantages of intermittent, high volatility, low controllability, etc. of photovoltaic power generation, and effectively alleviating the contradiction between the continuity of power generation and the intermittent nature of power consumption.

Structural components of the inverter

The structural components of the solar inverter inverter mainly include plastic parts, die-casting parts, radiators, heat sinks and other accessories.

The heat dissipation structural parts of solar converter for inverter are processed by profile processing, heating the metal to a semi-solid state, and then stretched and extruded by a mold. The products produced have advantages such as good extensibility, heat dissipation performance and surface quality.

The structural parts of photovoltaic inverter shell are formed by die casting, and the metal solution is injected into the metal mold under high pressure to form a casting. It has the characteristics of high wear resistance and high strength, and the molding structure is relatively complex, and the cost is relatively low.

The photovoltaic industry has certain requirements for precision structural parts, mainly including inverter structures, wire assemblies, photovoltaic brackets and other accessories. In the evolution trend of photovoltaic products constantly fitting with buildings, the degree of integration of photovoltaic products is getting higher and higher, which also puts higher requirements on precision structural parts.

HY's advantages

The two major features of the photovoltaic inverter shell are: the first is the use of high-quality aluminum alloy materials for die-casting; the second is that the depth of the heat dissipation ribs on the back of the shell exceeds 40-70mm, while the thickness is only about 1mm.

The three major difficulties in the development of the die-casting mold for the pv inverter shell include: the first is that the viscosity of the thermal conductive material is high and it is easy to stick to the mold; the second is that the ribs are deep and thin, and the molding defect rate is high; the third is that the ribs are deep, the mold structure is complex, and the ribs are not ejected smoothly.

HY's main products include precision die-casting structural parts, precision injection molding structural parts, profile stamping structural parts and other categories of structural parts, as well as metal molds, plastic molds and other categories of molds. The core products are widely used in photovoltaics, security, automobiles, consumer electronics and other fields.
