Study on Multi-field Coupling Characteristics of Heat Transfer Stress Model for Photovoltaic Panels
For the design and disassembly of photovoltaic panels,multiple sets of temperature sensors and thermal in-frared imagers are used to measure the temperature distribution on the surface of photovoltaic panels.Using the measured data of the temperature distribution on the surface of the photovoltaic panel as a reference,the multi-field coupling simu-lation was carried out using the heat-flow-force coupling model.The results show that the ambient temperature is an im-portant factor affecting the use of photovoltaic panels.The external ambient temperature is positively related to the sur-face temperature of photovoltaic panels,and the temperature difference between the cover plate and the back plate will gradually increase with the increase of the external temperature,and its reaches maximum 30℃ at 13:00.At this time,the shape variable of photovoltaic panels will also become larger.The vortex changed the direction of the fluid movement in the channel,resulting in uneven heat transfer of the fluid,and the temperature fluctuations caused stress fluctuations,resulting in uneven stress around the photovoltaic panel.
