Photovoltaic array liquid cooling system

Abstract

The invention discloses a photovoltaic array liquid cooling system. Assembly modules can be flexibly connected in series and in parallel by adopting independent modular liquid cooling plates, the flow channel resistance is small, installation and construction are easy, the operation and maintenance cost is reduced, and the purchase cost of parts is reduced through modularization and standardization; the heat-conducting silica gel pad is adopted to eliminate uneven cold and hot temperature of the photovoltaic module caused by the cooling flow channel, so that the performance of the module is stabilized and the generating capacity is improved; an independent centralized cooling water tower is adopted, no heat exchanger needs to be additionally arranged, the burden of an assembly square matrix is reduced, and the fault risk is greatly eliminated; the reservoir has a water purification function, so water quality is improved, blockage of a loop pipeline is avoided, and through scale generation of a liquid cooling plate, cooling power is reduced; and the independent photovoltaic power supply system can automatically and synchronously work with a cooling circulation system of a photovoltaic power station.
