Background technology
Inverter is that direct current energy (battery, accumulator jar) is transformed into alternating current (generally 220v50HZ sine or square wave).Popular says, inverter is a kind of device that unidirectional current (DC) is converted into alternating current (AC).It is made up of inverter bridge, control logic and filter circuit.It is widely used in air-conditioning, home theater, electric wheel, electric tool, sewing machine, DVD, VCD, computer, TV, washing machine, smoke exhaust ventilator, refrigerator, videocorder, masseur, fan, illumination etc., therefore inverter application in daily life is the most extensive.
In the photovoltaic application of solar energy, parallel network power generation is the important development trend of photovoltaic application, it has also become the principal mode of photovoltaic application.At present, existing photovoltaic combining inverter mostly is low power device, photovoltaic is confluxed after the DC current exported filters and carry out DC/AC conversion through overcurrent vreaker, it is connected to the grid by AC circuit breaker after carrying out ac filter again, in actual use, photovoltaic combining inverter can distribute a lot of heat, and the housing radiating effect of existing photovoltaic combining inverter is poor, and photovoltaic combining inverter easily burns out.
Summary of the invention
In order to overcome defect of the prior art, the purpose of this utility model is to provide that a kind of thermal diffusivity is good, the housing of the photovoltaic combining inverter of simple in construction.
The purpose of this utility model is achieved in that
The housing of photovoltaic combining inverter, the protecgulum being located on back cover including back cover and lid；The left plate inwall of described back cover and right plate inwall are respectively arranged with fin one and fin two, and on described fin one and fin two, equal array is provided with polygonal through hole；It is provided with the louvre of multiple penetrating setting on described left plate and right plate, the lateral surface of described left plate and right plate is provided with waterproof ventilated membrane.
Use after said structure, the radiating effect that can increase in housing is set by fin one and fin two, increase radiating effect further by arranging of polygonal through hole simultaneously；Arranging of waterproof ventilated membrane can make housing while heat radiation, and extraneous rainwater, impurity will not enter into enclosure interior, increase service life.
This utility model is further arranged to: the outer surface of described back cover and the outer surface of protecgulum are provided with antirust coat.
After using said structure, back cover and protecgulum can be avoided to be corroded, increase back cover and the service life of protecgulum.
This utility model is further arranged to: the outside of the left plate of described back cover and the right plate of back cover is respectively arranged with cover plate one and cover plate two, and described cover plate one and cover plate two are provided with the through hole one being correspondingly arranged with louvre.
After using said structure, add the structural strength of housing, heat can be also allowed for simultaneously and outwardly distributed by through hole one, improve radiating effect.
This utility model is further arranged to: offer the ventilation slot of penetrating setting on the base plate of described back cover, and described ventilation slot is covered with heat sink, and described heat sink is provided with many radiating ribs.
After using said structure, increase thermal diffusivity further.
This utility model is further arranged to: described polygonal through hole is equilateral triangle.
After using said structure, while increasing thermal diffusivity, improve structural stability.
This utility model is further arranged to: described polygonal through hole is regular hexagon.
After using said structure, material can also be reduced while increasing thermal diffusivity, and improve structural stability.
