Abstract
The utility model discloses a radiating structure for an anti-reverse diode in a photovoltaic combiner box. The radiating structure comprises a case and a radiator, wherein the radiator is arranged on the outer wall of the case, the case is provided with mounting holes for mounting the anti-reverse diode at a position where the radiator is mounted, and the anti-reverse diode is mounted on the radiator through the mounting holes. The radiating structure is simple in structure, adopts a structure that the radiator is arranged externally so that fins thereof are exposed out of the case and the heat produced by the anti-reverse diode can be directed exchanged with the outside for radiation, realizes the sealing of the case by painting weather-proof sealant between the radiator and the case, and ensures that the protection class of the case can reach IP65, thereby improving the reliability and prolonging the service life of the photovoltaic combiner box, and being worthy of popularization and application.
Description
Technical field
The utility model relates to a kind of radiator structure, is specifically related to the radiator structure that uses on a kind of counnter attack diode, belongs to the radiator structure design field.
Background technology
The work under bad environment of photovoltaic header box, than higher, in order to guarantee the water proof and dust proof performance of cabinet, the general employing is installed in the mounting means of header box cabinet inside with the counnter attack diode with radiator at present to the requirement of shelter of cabinet.Because the counnter attack diode is big in the caloric value of the course of work, there is the problem that can't realize good heat exchange with the outside in this layout, and header box cabinet inside heat accumulation causes the inner components and parts of counnter attack diode and header box to burn out easily.In actual use, header box tripping operation often occurs or burn and situation that photovoltaic module burns, have a strong impact on normal power generation efficient and the reliability of electricity generation system, therefore need the bad situation that causes circuit breaker trip and burn of counnter attack diode radiating that solves badly, reliability and the useful life of improving system works.
The utility model content
The purpose of this utility model is to propose at above-mentioned technical problem a kind of simple and compact for structure, can effectively improve the radiator structure of the photovoltaic header box counnter attack diode of counnter attack diode radiating situation, stability and reliability when improving header box work.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of radiator structure of photovoltaic header box counnter attack diode comprises cabinet, radiator; Described radiator is arranged on the described cabinet outer wall, described cabinet offers the installing hole that the counnter attack diode is installed in described radiator installation place, the counnter attack diode is installed on the described radiator by described installing hole, the heat that the counnter attack diode produces is dispersed by the outside fin realization of the radiator nature that is installed on the described cabinet outer wall, guaranteed the operate as normal of system.
As further improvement of the utility model, described plate radiator and the cabinet back side connect by fastening bolt and to interconnect fixingly, guarantee that radiator is fixed on the described cabinet outer wall reliably.
As further improvement of the utility model, described radiator and cabinet junction are provided with one deck weather proofing sealant, the strictness sealing is carried out in slit between described radiator and the cabinet, satisfied the requirement of the waterproof and dustproof of photovoltaic header box, make the degree of protection of photovoltaic header box reach IP65, reach the desired degree of protection of photovoltaic header box.
As further improvement of the utility model, described radiator is plate radiator.
The utility model is simple in structure, adopt external its fin that makes of radiator directly to expose the heat externally directly exchange heat radiation rapidly that the structure in the cabinet outside produces the counnter attack diode, and by between radiator and cabinet by smearing weather proofing sealant, realize the sealing of cabinet, guarantee that the cabinet degree of protection reaches IP65, improved reliability and the useful life of photovoltaic header box, be worthy of popularization.
