Description
技术领域technical field
本实用新型涉及结构工艺技术领域，特别涉及一种光伏逆变器机柜。The utility model relates to the technical field of structure technology, in particular to a photovoltaic inverter cabinet.
背景技术Background technique
伴随科技的日益发展，不同需求规格的逆变器应用而生。现有技术中，为了节能环保各式各样的光伏逆变器也进入市场。然而，光伏逆变器受现有技术制约，其逆变效率普遍在97％左右。大功率的光伏逆变器发热功率很大。在现今这个工业小型化的时代，高功率密度的光伏逆变器散热解决方案是一个技术难点。对于可在室外环境工作的大功率光伏逆变器，解决散热问题更是艰难。With the increasing development of science and technology, the application of inverters with different requirements and specifications has emerged. In the prior art, various photovoltaic inverters have entered the market for energy saving and environmental protection. However, photovoltaic inverters are limited by existing technologies, and their inverter efficiency is generally around 97%. High-power photovoltaic inverters generate a lot of heat. In today's era of industrial miniaturization, the heat dissipation solution for high power density photovoltaic inverters is a technical difficulty. For high-power photovoltaic inverters that can work in outdoor environments, it is even more difficult to solve the problem of heat dissipation.
现在技术中，大功率的室外光伏逆变器较少，多为小功率自冷形式。逆变部分通过机壳与外界空气隔离，功率器件安装在很大的散热基板上。通过此种形式达到室外工作和散热的目的。然而，现有技术中散热基板笨重，多为铝或铝合金材质，制造成本很高，且此种方式无法延伸应用于大功率的光伏逆变器。In the current technology, there are few high-power outdoor photovoltaic inverters, and most of them are low-power self-cooling forms. The inverter part is isolated from the outside air through the casing, and the power devices are installed on a large heat dissipation substrate. Through this form, the purpose of outdoor work and heat dissipation is achieved. However, the heat dissipation substrates in the prior art are bulky, mostly made of aluminum or aluminum alloy, and the manufacturing cost is high, and this method cannot be extended and applied to high-power photovoltaic inverters.
现有技术中，部分室外大功率光伏逆变器采用水冷形式，通过使用水冷热交换器来满足散热需求。但是，室外大功率光伏逆变器的结构工艺很复杂，水冷热交换器成本很高。In the prior art, some outdoor high-power photovoltaic inverters are water-cooled, and a water-cooled heat exchanger is used to meet heat dissipation requirements. However, the structure and process of outdoor high-power photovoltaic inverters are very complicated, and the cost of water-cooled heat exchangers is very high.
