Abstract

The invention relates to a cooling device of a solar battery system. The solar battery system comprises a solar battery component array consisting of at least two solar battery components, wherein each solar battery component is provided with a solar battery laminating part and a frame, and is also provided with an attachment layer; the attachment layer is connected with the frame; a space is arranged between the solar battery laminating part and the attachment layer; cooling liquid flows in the space and realizes internal and external circulation in the space by at least two opening holes; the opening holes are a cooling-liquid inlet and a cooling-liquid outlet respectively; and the cooling liquid circulates among all the solar battery components by channels which are connected in series and / or in parallel. The cooling device has the advantages that the solar battery components are lower in temperature, high in generating capacity, uniform in temperature and almost can not generate hot-spot effect, and back plates and EVA of the components are long in service life; the cooling-liquid inlet and the cooling-liquid outlet are arranged on the frame, the adjacent solar battery components can be tightly attached, so that the use of pipelines is reduced, the cost is saved and the space utilization ratio is improved.
