The technical problems to be solved in the utility model is to provide a kind of photovoltaic conflux box structure of improvement, can solve the deficiencies in the prior art, under the prerequisite of degree of protection not destroying photovoltaic combiner box IP65, decreases because hermetically-sealed construction is to the impact brought of dispelling the heat.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of photovoltaic conflux box structure of improvement, comprise casing, the arranged outside of described casing has outer liner plate, space is provided with between casing and outer liner plate, the top in space communicates with the external world, the outside of casing tilts upward and is provided with several outer fin, the angle of outer fin and casing is 20 ° ~ 45 °, outer fin is provided with the first through hole of vertical direction, the bottom surface of outer fin is provided with two leading chutes, the top of each leading chute is connected with two secondary guiding gutters, beyond two leading chutes, the center line of fin is that symmetry axis is symmetrical arranged, angle between two secondary guiding gutters is 35 ° ~ 55 °, outer liner plate is provided with the second through hole, the axis of the second through hole and the angle of outer fin are 75 °, the inner side of casing is provided with and outer fin interior fin one to one, interior fin is cambered surface, heat generating components Elastic Contact in the top cambered surface of interior fin and casing, casing is provided with several third through-holes, interior fin and outer fin are rigidly connected in third through-hole, sealing ring is provided with in third through-hole.
As preferably, the bottom in the space between described casing and outer liner plate is provided with rhone.
As preferably, to being arranged with two baffle plates in the sidewall of described rhone, two baffle plates tilt towards offside respectively, and two baffle plate in the vertical directions partly overlap; The top in the space between described casing and outer liner plate is provided with screen pack.
The beneficial effect adopting technique scheme to bring is: the utility model, at the outer liner plate of casing arranged outside, makes to be formed with space of dispelling the heat between casing and outer liner plate.The heat of box house is passed to heat radiation position, space by interior fin and outer fin, temperature in heat radiation space is raised, air heats forms the air-flow upwards flowed, and extraneous cold air constantly fills into heat radiation space from the second through hole, forms a lasting radiating airflow and circulates.Cold air upwards flows along the second through hole, contact with the bottom surface of outer fin after entering heat radiation space, and then enter secondary guiding gutter along leading chute, finally flow out from the both sides diffusion of outer fin, first through hole can provide a passage upwards flowed to hot-air, thus make a heat radiation space inside formation cold air constantly enter and carry out heat exchange with outer fin, the circulating path that the air that then temperature raises upwards flows out along the first through hole.This circulating path obviously can accelerate the flowing velocity of air, improves the heat exchanger effectiveness of outer fin, thus reaches the effect to quick heat radiating cooling in casing.When external environment wind speed is larger, air-flow at a high speed flows into from the second through hole, forms regions of turbulent flow, better heat-radiation effect by air-flow interaction in heat radiation space of leading chute and secondary guiding gutter.The direct Elastic Contact of heat generating components in interior fin and casing, can improve heat conduction efficiency, sealing ring can ensure that the IP65 degree of protection of casing is not destroyed.Rhone can prevent the space ponding between casing and outer liner plate.Two baffle plates be crisscross arranged can prevent introduced contaminants from directly entering rhone and produce blocking while playing drainage effect, and screen pack can reduce the space that extraneous impurity descends slowly and lightly between inlet body and outer liner plate.
