Description
Technical field
The present invention relates to the component units of photovoltaic generating system, specifically 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 that 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 again inverter air-cooled circulation consider essential intake.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, the circulation in cabinet such as salt fog, conductive particle occurs.
Summary of the invention
Technical problem to be solved by this invention is, a kind of seal that can either improve the inversion unit device is provided, and strengthens its insulating protection ability, can guarantee again the hermetic type photovoltaic inversion unit cabinet that the heat radiation of inversion unit device requires.
Hermetic type photovoltaic inversion unit cabinet of the present invention includes cabinet, and the cabinet inner chamber is front cabinet and rear cabinet two parts by baffle for separating, and the power cell device is installed in the front cabinet; Described rear cabinet bottom is provided with the air-inlet cavity that is communicated with air inlet, after cashier's office in a shop section 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 present invention 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.

Fig. 1 is structural representation of the present invention.
Embodiment
Hermetic type photovoltaic inversion unit cabinet of the present invention includes cabinet 1, and the cabinet inner chamber is divided into front cabinet 11 and rear cabinet 12 two parts by dividing plate 10, and power cell device 2 is installed in the front cabinet; Described rear cabinet 12 bottoms are provided with the air-inlet cavity 13 that is communicated with air inlet, after cashier's office in a shop section 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.
