PASSIVE COOLING SYSTEM FOR PHOTO VOLTAIC MODULES

摘要

The present invention discloses a cooling fin assembly for Photo Voltaic Solar (PVS) panels providing an improved passive cooling of the PVS panels. Cooling fins as such do provide a good local cooling effect underneath the contacting surface of the fins. However, due to uneven air streams around the cooling fins, the temperature difference across a transversal direction relative to the direction of the fins may be high. This causes a severe degradation of the cooling systems effectiveness, and the resulting output form the PVS panel. According to the disclosure of this invention, an arrangement of transversal heat conducting materials provides a heat bridge providing a thermal relaxation time below a predefined threshold across the whole back side of the PVS panel, thereby improving the overall cooling effect of the PVS panel.
