Electrically isolated heat dissipating junction box

摘要

A junction box used for making electrical connections to a photovoltaic panel. The junction box has two chambers including a first chamber and a second chamber and a wall common to and separating both chambers. The wall may be adapted to have an electrical connection therethrough. The two lids are adapted to seal respectively the two chambers. The two lids are on opposite sides of the junction box relative to the photovoltaic panel. The two lids may be attachable using different sealing processes to a different level of hermeticity. The first chamber may be adapted to receive a circuit board. The junction box may include supports for mounting a printed circuit board in the first chamber. The second chamber is configured for electrical connection to the photovoltaic panel. A metal heat sink may be bonded inside the first chamber. The first chamber is adapted to receive a circuit board for electrical power conversion, and the metal heat sink is adapted to dissipate heat generated by the circuit board.

1. A junction box comprising:
a first chamber comprising a circuit board designed to convert electrical power from one or more power outputs of a photovoltaic panel; a second chamber comprising an electrical connection designed to receive the electrical power from the one or more power outputs of the photovoltaic panel; a wall common to and separating the first chamber and the second chamber; a first lid designed to seal the first chamber against ingress of water or humidity with a first level of hermeticity; and a second lid designed to seal the second chamber against ingress of water or humidity with a second level of hermeticity different from the first level of hermeticity.
