NOVELTY - A heat dissipation system comprises a heat dissipating assembly (16) including a heat dissipating portion (36) and heat emitting electrical component(s). Each heat emitting electrical component has a heat sink element. The heat dissipating portion is sufficiently proximate to at least an additional portion of the electrical component to further dissipate generated heat. The heat dissipating portion includes electrical contact(s) electrically connected to the electrical component.    USE - A heat dissipation system for photovoltaic array interconnection system used in a power distribution system.    ADVANTAGE - The system provides improved heat dissipation from the components within the junction box; is easily fabricated; and allows additional environmental protection for the electrical components present in the junction box. Multiple photovoltaic components may be connected to a single junction box. Components having increased heat emission and/or photovoltaic components having increased current capacity may be utilized within the junction box.    DETAILED DESCRIPTION - A heat dissipation system comprises a heat dissipating assembly (16) including a heat dissipating portion (36) and heat emitting electrical component(s). Each heat emitting electrical component has a heat sink element attached to the heat dissipating portion. The heat dissipating portion is sufficiently proximate to at least an additional portion of the electrical component to further dissipate generated heat. The heat dissipating portion includes electrical contact(s) electrically connected to the electrical component. An enclosure receives a portion of the heat dissipating portion and external power input wiring by electrical contact with the electrical contact. The heat emitting electrical component is a diode, TO-220 packaged diodes having heat sink tabs, or ITO-220AC diodes having plastic covered heat sinks. An INDEPENDENT CLAIM is included for interconnection system (10) for solar cell arrays in a power distribution system, comprising at least one electrical current producing device (preferably photovoltaic cell or photovoltaic array); and a junction box (12) connecting the current producing devices, and comprising an enclosure and a heat dissipating assembly.
