Description
Technical field
The utility model relates to a kind of solar grid-connected inverter casing.
Background technology
In short supply due to conventional energy resource, and the pollution to natural environment, solar energy is paid attention to gradually, and it is considered to new energy technology the most promising in the world today.Solar grid-connected inverter is converted to electric energy by solar energy, is incorporated to public electric wire net, forms grid-connected photovoltaic power generation system, and the user on power supply network uses; Solar power system, clean environment firendly, inexhaustible.Solar grid-connected inverter internal main is wanted heater members: IGBT module, inductance, transformer, metal-oxide-semiconductor.Solar grid-connected inverter operational environment is not equipped with air-conditioning mostly at present, and some is also contained in outdoor, therefore the waterproof of solar grid-connected inverter, heat radiation is had higher requirement.The structure of the hermetically sealed body of employing having for waterproof, although this structure can waterproof, but be unfavorable for the dissipation of heat of internal body, cause air in body cannot normal circulation, circulation comes, and the stability of combining inverter and life-span have been produced to very large impact.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provide a kind of water resistance good, can effectively to dispelling the heat in body, improve solar grid-connected inverter performance, the solar grid-connected inverter casing mutually not restricting.
In order to achieve the above object, the utility model is achieved in that it is a kind of solar grid-connected inverter casing, is characterized in that comprising:
Face-piece is equipped with air inlet on left and right two walls of described face-piece;
Mounting box, described face-piece covers on mounting box, on left and right two walls of described mounting box, is equipped with air intake vent, and left and right two walls of mounting box and left and right two walls of face-piece are gapped;
Ventilating fan, described ventilating fan is arranged on lower wall or the upper wall of mounting box; And radiator, at the bottom of described radiator is close to the box of mounting box.
Bottom at described radiator is provided with radiator fan.
On described radiator, back bracket is installed, in described back bracket, is provided with dismountable hanger plate.
Described air inlet is located at the below of left and right two walls of face-piece; Described air intake vent is located at the top of left and right two walls of mounting box.
At the bottom of the box of described mounting box, have IGBT louvre.
The utility model advantage is compared with prior art: water resistance is good, can improve solar grid-connected inverter performance effectively to dispelling the heat in body, does not mutually restrict.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.At this, it should be noted that, for the explanation of these execution modes, be used for helping to understand the utility model, but do not form restriction of the present utility model.In addition,, in each execution mode of described the utility model, involved technical characterictic just can not interosculate as long as do not form each other conflict.
In the utility model is described, term " left side ", " right side ", " on " and orientation or the position relationship of the indication such as D score be based on orientation shown in the drawings or position relationship, it is only the utility model rather than require the utility model with specific orientation structure and operation, therefore can not be interpreted as restriction of the present utility model for convenience of description.
As shown in Figures 1 to 6, it is a kind of solar grid-connected inverter casing, comprising:
Face-piece 3 is equipped with air inlet 31 on left and right two walls of described face-piece 3, face-piece 3 upper and lower opening-like;
Ventilating fan 5, described ventilating fan 5 is arranged on lower wall or the upper wall of mounting box 4, and ventilating fan 5 can be discharged the hot-air in mounting box 4 outside mounting box 4 and face-piece 3; And
During work, extraneous air enters from the air inlet 31 of face-piece 3, by gap 34 and air intake vent 41, enter in mounting box 4 successively again, heat in last mounting box 4 is discharged by ventilating fan 5, can be effectively to dispelling the heat in mounting box 4, prevent that rainwater from wafing in mounting box 4, improved the safety and stability performance of solar grid-connected inverter.
In the present embodiment, in order further mounting box 4 to be dispelled the heat, on bottom or the top of described radiator 1, radiator fan 7 is installed; During work, radiator fan 7 can accelerate the loose gesture of radiator 1.
In the present embodiment, for the ease of installing, on described radiator 1, back bracket 2 is installed, in described back bracket 2, is provided with dismountable hanger plate 6.
In the present embodiment, for more effective, prevent that rainwater from wafing in mounting box 4, described air inlet 31 is located at the below of left and right two walls of face-piece 3; Described air intake vent 41 is located at the top of left and right two walls of mounting box 4.The air intake vent up and down 41 of this dislocation and air inlet 31 can effectively prevent that rainwater from wafing into the erosion of 4 pairs of internal components of mounting box.
In the present embodiment, for mounting box 4 is better dispelled the heat, at the bottom of the box of described mounting box 4, have louvre 42.
Below by reference to the accompanying drawings execution mode of the present utility model is made to detailed description, but the utility model is not limited to described execution mode.For the ordinary skill in the art, in the situation that not departing from principle of the present utility model and aim, these execution modes being carried out to multiple variation, modification, replacement and distortion still falls within protection range of the present utility model.
