Abstract

The invention relates to a cooling system of a photovoltaic power generation module. The cooling system solves the technical problems that a current photovoltaic power generation module is over-high in running temperature and heat is lost and wasted. The cooling system comprises a photovoltaic power generation module and is characterized in that an absorber plate is arranged on one side of the photovoltaic power generation module, a working medium channel is arranged in the absorber plate, and the absorber plate is communicated with a compressor and a heat exchange device through a working medium conduit to form a loop. The running temperature of the photovoltaic power generation module is reduced, attenuation of a system is reduced, the service life of the system is prolonged, photovoltaic power generation efficiency is improved, the heat generated in running of the photovoltaic power generation module is recycled, and loss and waste of the heat are avoided.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a cooling system for photovoltaic power generation components. Background technique [0002] As a key industry for solar energy utilization, photovoltaics are now encountering the problems of low efficiency in converting sunlight into electricity and serious system attenuation in photovoltaic power generation systems.
