A dynamic regulation method of a photovoltaic welding strip copper wire dual-phase cooling flow field

Abstract

The application discloses a dynamic regulation method for a photovoltaic welding strip copper wire dual-phase cooling flow field. The method comprises the following steps: temperature monitoring of a cooling environment, obtaining temperature data of the photovoltaic welding strip copper wire and a liquid cooling device respectively, calculating the required cooling load required by the copper wire in the current motion state to reach the preset cooling target; determining the cooling air flow dynamic state according to the spatial distribution characteristics of the required cooling load, and executing the first air cooling regulation to realize the global cooling uniformity control; obtaining the cooling medium heat exchange real-time data of the liquid cooling device, predicting the heat load trend and adjusting the flow state of the cooling medium; obtaining the humidity and temperature distribution data of the cooling environment, estimating the water vapor condensation state, and executing the second air cooling regulation to remove the local condensed water. The application realizes uniform cooling of the copper wire, actively manages the heat load of the liquid cooling system, and removes the condensed water in time, thereby improving the cooling efficiency and the copper wire surface quality, and being suitable for the wire drawing post-cooling process in the photovoltaic welding strip production.
