Sealed type photovoltaic junction box with rapid heat dissipation

Abstract

The invention relates to a sealed type photovoltaic junction box with rapid heat dissipation, which comprises a box body, a box cover and a metal terminal that is sealed inside the box body and the box cover and is provided with a diode. The box body and the box cover are sealed with silicone, a sealant filling region is arranged at the upper part of the box cover and is sealed through a sealant filling upper cover which is provided with a sealant filling hole at the middle part thereof, an adhesive groove is arranged on the periphery of the box cover, the box body adopts hollowed design, a vent hole is arranged in the middle of the box body, adhesive bulges matched with the adhesive groove are arranged on the periphery of the box body, an upper wire clamping semicircular slot and a lowerwire clamping semicircular slot that are matched with each other in the vertical direction are arranged on each side surface of the box body and the box cover, the metal terminal adopts large-area thin-sheet design, and cables are connected with the two ends of the metal terminal and are placed inside the wire clamping semicircular slots. The sealed type photovoltaic junction box provided by the invention adopts silicone sealing, thereby resulting in better sealing performance, improved waterproof and dustproof capacity, good heat dissipation performance, and the like.

Description

Technical field: [0001] The invention relates to a junction box, in particular to a sealed fast heat dissipation photovoltaic junction box. Background technique: [0002] At present, most of the traditional connection methods between the junction box and the battery slice of the module are made of silica gel, and the back of the box body is bonded to the battery slice, which causes the heat generated by the junction box to be transferred to the battery slice, which will affect the service life of the module; and Most of the traditional junction box sealing methods are sealed with silicone rings. After long-term use, the silicone rings are likely to age and not be waterproof. Invention content: [0003] The purpose of the present invention is to provide a photovoltaic junction box with good sealing performance, rapid heat dissipation, and enabling the photovoltaic module to work as efficiently as possible within the effective service life period. [0004] The technical sol...
