Flat plate solar panel core with efficient heat collection function and preparation method thereof

Abstract

The invention provides a flat plate solar panel core with an efficient heat collection function and a preparation method thereof, and relates to the technical field of solar energy utilization. The flat plate solar panel core comprises a heat collection plate and a heat conduction pipe; the heat conduction pipe is welded with an aluminum strip, the aluminum strip is provided with a groove matchedwith the heat conduction pipe, and the groove enables the heat conduction pipe to be embedded in the aluminum strip, and the heat conduction pipe is welded to the back face of the heat collection plate through the aluminum strip. The flat plate solar panel core with an efficient heat collection function and the preparation method thereof have the advantages that the groove is adopted, so that theheat transfer area is maximized, the heat transfer efficiency is greatly improved; the heat conduction pipe is welded to the aluminum strip through ultrasonic waves so that the connection between theheat conduction pipe and the aluminum strip is firm, and the situation of descending of the heat transfer efficiency can be prevented; the aluminum strip is adopted to be welded to the back face of the heat collection plate, thereby improving the heat collection efficiency of the heat collection plate, and making the appearance of the heat collection plate attractive; therefore, the connection ofthe solar panel core is firm, the heat transfer efficiency is high, the cost is lower, and the appearance quality of the surface of the heat collection plate is not affected.

Description

Problems solved by technology

As an important part of heat conversion and transmission, the heat collector plate core has a direct impact on the performance of flat-panel solar collectors due to its structure and performance. However, most of the current flat-plate solar plate cores are welded by ultrasonic front welding or laser back welding. , the front welding destroys the heat-absorbing coating and affects the appearance of the collector. Laser welding belongs to spot welding, the heat exchange area is small and the equipment is complicated, and maintenance is not easy, which limits the widening of the application range of solar collectors.
