Abstract
The utility model relates to a composition unit of a photovoltaic power generation system and specifically relates to an enclosed photovoltaic inversion unit cabinet. The enclosed photovoltaic inversion unit cabinet comprises a cabinet body, wherein an inner chamber of the cabinet body is divided into a front cabinet and a back cabinet by a baffle plate, the front cabinet is mounted with a power unit device, a lower portion of the back cabinet is provided with an air inlet chamber communicated with an air inlet, an upper portion of the back cabinet is provided with an air outlet chamber which is communicated with an air outlet and a fan at a top portion, the air inlet chamber and the air outlet chamber are communicated through a segment of air channel, the power unit device is mounted on a heat radiator base plate which is arranged at a front side face of the baffle plate, a back face of the heat radiation base plate is connected with heat radiation fins, and the heat radiation fins penetrate through the baffle plate to enter the air channel. The enclosed photovoltaic inversion unit cabinet not only realizes effective heat radiation of a power unit through heat radiation air flow, but also can make moisture and corrosivity gas not enter mounting space of the power unit, and thereby protection capability is improved.
Description
Technical field
The utility model relates to the component units of photovoltaic generating system, specifically is a kind of hermetic type photovoltaic inversion unit cabinet.
Background technology
In the high-power photovoltaic synchronization inverter, the composition form of power inverting unit has multiple, depends primarily on the arrangement of IGBT module and the composition form of control figure plate.Power cell is as the core cell of photovoltaic combining inverter, wherein the drive plate of IGBT module, control with digiboard and be incorporated into the power networks very high to environmental requirement with digiboard etc., particularly when photovoltaic DC-to-AC converter during for particular surroundingss such as coastal, plateau, northern areas.And photovoltaic DC-to-AC converter substantially all is the mode of taking wind-cooling heat dissipating at present, and the mode of wind-cooling heat dissipating has just determined airborne aqueous vapor, salt fog, conductive particle etc. can appear in the photovoltaic DC-to-AC converter, will give in the cabinet senser particularly the PCB digiboard bring threat.
Therefore should the cabinet high-protection level, make inverter air-cooled circulation consider essential intake again.The method that aqueous vapor is removed in current inverter cabinet design mainly takes to increase in the cabinet heater and Temperature Humidity Sensor, the mode of removing salt fog is that digiboard is carried out protective treatment, these all are interim measure, can't the radical change aqueous vapor, circulation in cabinet such as salt fog, conductive particle occurs.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of seal that can either improve the inversion unit device is provided, and strengthens its insulating protection ability, can guarantee the hermetic type photovoltaic inversion unit cabinet that the heat radiation of inversion unit device requires again.
Hermetic type photovoltaic inversion unit cabinet of the present utility model includes cabinet, and cabinet and back cabinet two parts were equipped with the power cell device before the cabinet inner chamber was divided into by dividing plate in the preceding cabinet; Cabinet bottom, described back is provided with the air-inlet cavity that is communicated with air inlet, after cashier's office in a shop portion be provided with the air-out chamber that is communicated with the blower fan at air outlet and top, be connected by one section air channel between air-inlet cavity and the air-out chamber; Described power cell device is installed on the radiator base plate that is positioned on the described dividing plate leading flank, and the back side of described radiator base plate is connected with radiating fin, and radiating fin passes dividing plate and extend in the described air channel.
The utility model is by separating air-cooled passage and the installing space of power cell mutually, and the radiating fin of radiator is placed in the air channel, make radiating airflow when effectively taking away the power cell heat, can not make the installing space of steam and corrosive gas ingoing power unit, thereby strengthen protective capacities.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Hermetic type photovoltaic inversion unit cabinet of the present utility model includes cabinet 1, and cabinet 11 and back cabinet 12 two parts were equipped with power cell device 2 before the cabinet inner chamber was divided into by dividing plate 10 in the preceding cabinet; Cabinet 12 bottoms, described back are provided with the air-inlet cavity 13 that is communicated with air inlet, after cashier's office in a shop portion be provided with the air-out chamber 14 that is communicated with the blower fan 3 at air outlet and top, be connected by one section air channel 15 between air-inlet cavity 13 and the air-out chamber 14; Power cell device 2 is installed on the radiator base plate 4 that is positioned on dividing plate 10 leading flanks, and the back side of radiator base plate 4 is connected with radiating fin 41, and radiating fin 41 passes dividing plate 10 and extend in the air channel 15.
