Abstract

The invention discloses a cooling type solar battery assembly and a manufacturing technology of the cooling type solar battery assembly. The solar battery assembly is formed by connecting solar photovoltaic glass, a first cooling packaging adhesive film, a battery piece, a second cooling packaging adhesive film, a thin PET insulating film, a third cooling packaging adhesive film, a metal cooling back plate, structural adhesive and a metal supporting beam sequentially from top to bottom. The manufacturing technology comprises the steps of stacking, defect inspection, lamination and installation of a junction box and the supporting beam. Compared with an existing conventional solar battery assembly, the cooling type solar battery assembly effectively improves heat conduction and cooling by the adoption of cooling packaging adhesive films of high heat conductivity in cooperation with the metal cooling back plate of high heat transfer coefficients; in this way, the output power of the solar battery assembly is effectively increased, and power generation benefits are increased; besides, the manufacturing technology also has the advantages that the technological method is advanced, and technological equipment is simple.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a heat dissipation type solar cell assembly and its manufacturing process. Background technique [0002] Traditional solar cell modules generally use EVA (Ethylene-Vinyl Acetate copolymer ethylene-vinyl acetate copolymer) to encapsulate and protect the cells, and use high weather resistance fluorine film material as the back sheet to protect the components from the erosion of external environmental conditions. The use of the above materials can ensure that the service life of the components meets the requirements of 25 years. [0003] However, due to the average heat transfer and heat dissipation performance of the above two polymer materials, the heat generated by the module when it generates electricity outdoors cannot be effectively dissipated, and the accumulated heat greatly reduces the electrical output performance of the module. Contents of the invention [0004] Th...
