Description
Technical field
The utility model relates to a kind of modular construction of photovoltaic generating system, specifically a kind of photovoltaic DC-to-AC converter waterproof radiating structure.
Background technology
In photovoltaic generating system, the reliability service of outdoor power system case has important function.But the problem of outdoor power system maximum is to guarantee the heat radiation of casing at present, also will avoid simultaneously rainwater to infiltrate casing, and the components and parts in the casing are caused damage.Present outdoor power system case is in the side of casing or positive offer heat dissipation channel and guarantee to dispel the heat, is difficult to like this guarantee that rainwater can not infiltrate in the casing from heat dissipation channel.In addition, the unreasonable discharging of components and parts in the casing causes components and parts heat radiation phase mutual interference in the casing, and the heat that can not timely and effectively each components and parts in the casing be distributed is discharged.
The utility model content
Technical problem to be solved in the utility model is; a kind of good ventilation and heat ability that both had is provided; can carry out again stronger water-tight protection, the photovoltaic DC-to-AC converter waterproof radiating structure that the equipment operational reliability is high to the circuit element that comprises power cell simultaneously.
Photovoltaic DC-to-AC converter waterproof radiating structure of the present utility model includes a casing, and casing is epicoele and cavity of resorption by the baffle for separating at middle part, and the IGBT element and the wiring board that consist of inverter circuit are installed in the described epicoele; Radiator also is installed in the casing, described radiator is comprised of radiator base and the radiating fin that is connected to the radiator base back side, described radiator base is arranged in epicoele, and the opening that radiating fin passes dividing plate enters in the cavity of resorption, and the edge of opening of radiator base and dividing plate is tightly connected; Described IGBT element is connected with the positive contact of radiator base; Be respectively arranged with air intake blower fan and air draft shutter on a pair of relative wallboard of described cavity of resorption, in the air channel of described radiating fin between air intake blower fan and air draft shutter.
Be provided with water joint on the described dividing plate, the power supply lead wire process water joint of described air intake blower fan is connected with the wiring board in the epicoele.
Also be provided with waterproof vent valve on the described dividing plate, be used for discharging the steam of epicoele.
Difference, weak control circuit and the forceful electric power main circuit that the utility model requires for the different components degree of protection isolated and the requirement of shielding and the requirement of power device heat radiation mutually, the overall structure of product is divided into the Dual-layer cavity, realizes mutual isolation, shielding and independent sealed; Its epicoele has good waterproof sealing, has satisfied the higher waterproof requirement of the elements such as IGBT, has guaranteed simultaneously the rapid discharge of system thermal by the cooling system of cavity of resorption, has improved the operational reliability of system.
