| 摘要 |
The invention relates to a junction box which safely carries off the heat produced in the bypass diodes (1), MOSFETs or suitable power semi-conductors of a solar module. Said junction box comprises a housing (2, 3) that consists of a base body (2) and a housing cover (3) that can be placed thereon. At least one receiving chamber (5) is arranged on at least one lateral wall of the base body (2) and protrudes in a distal manner from the lateral wall. In the at least one receiving chamber (5), at least one electric component (1) that is surrounded by an insulating cover (7) is arranged, said component resting firmly on the inner side of the receiving chamber (5) and on the housing cover (3). The cover (3) is made of extruded aluminium, comprises cooling ribs and overlaps the contour of the base body (2). The junction box can be used for solar modules with bypass flows from upto 16 A and higher. |
