Abstract

The invention discloses a device for enhancing heat dissipation of a water surface photovoltaic module by using a phase change material, which comprises a photovoltaic module, a phase change material,a metal box and a floating body material. The phase change material is encapsulated in the metal box and placed on the back of the photovoltaic module, and the floating body material is pasted on thebottom of the metal box. The invention combines the phase change material with the water surface photovoltaic module, utilizes the principle that the phase change material absorbs heat in the phase change process and the temperature maintains stable and unchanged, not only can the temperature of the photovoltaic board be prevented from being too high, the power generation efficiency of the photovoltaic module is improved, but also the service life of the photovoltaic module can be prolonged, and the preparation process of the device is simple, and the device is suitable for large-scale production.

Description

technical field [0001] The invention relates to a device for enhancing the heat dissipation of a photovoltaic module on a water surface by using a phase change material, and belongs to the field of photovoltaic modules. Background technique [0002] The increasing demand for energy in social development has led to the extreme shortage of fossil fuels such as coal and oil and the increasingly prominent environmental problems. Clean energy has received more and more attention. As a kind of clean energy, solar energy has the advantages of non-pollution and renewable. Photovoltaic power generation is a kind of solar energy utilization, which has the advantages of safety, reliability, no noise, and no pollution emissions. However, due to the low energy density of solar energy, traditional ground photovoltaic power plants need to occupy a large amount of land resources, making the cost of power generation too high. The emergence of water surface photovoltaics provides a solution...
