Embodiment
Below with reference to Figure of description and specific embodiment the utility model is described in further details.
Concrete application example 1 as shown in Figure 1, the utility model is used for the cabinet of outdoor type photovoltaic power generation equipment, comprise cabinet 6 and lamina tecti assembly 1, the photovoltaic inversion unit 7 of photovoltaic power generation equipment is installed on the inside of cabinet 6, and lamina tecti assembly 1 is installed on the top of cabinet 6.Photovoltaic inversion unit 7 should comprise power cell and several non-power unit components according to routine, and power cell and other all non-power unit components all have separately independently exhaust blower and air channel.(this example is on the side of cabinet 6) offers main wind inlet channel 8 and an auxiliary wind inlet channel 10 on the cabinet 6, offers a plurality of auxiliary air inlets 9 that are communicated with this auxiliary wind inlet channel 10 at cabinet 6.One end of main wind inlet channel 8 is communicated with outside air or extraneous cooling wind regime, and the other end is communicated with the air channel of power cell; One end of auxiliary wind inlet channel 10 and outside air or extraneous cooling wind regime are communicated with, the other end with the air channel connection of corresponding non-power unit component.Lamina tecti assembly 1 comprises and covers housing 11 and be opened in two wind guide channels 3 that cover in the housing 11, the entrance point of a wind guide channel 3 is communicated with main wind inlet channel 8, the entrance point of another wind guide channel 3 is communicated with auxiliary wind inlet channel 10, and the port of export of each wind guide channel 3 is equipped with the air outlet 4 that is communicated with cabinet outward.
Be appreciated that also plural auxiliary wind inlet channel 10 can be set according to actual needs the independent ventiduct of each auxiliary wind inlet channel 10 corresponding non-power unit component; And also corresponding wind guide channel 3, namely the quantity of wind guide channel 3 equals all auxiliary wind inlet channels 10 and main wind inlet channel 8 sums in the lamina tecti assembly 1.The structure of this form also should belong within the protection range of the present utility model.
In the present embodiment, windproof anti-filling device 2 all is set in that each wind guide channel 3 is interior, only allow air-flow from wind guide channel 3 discharged to the external world, and do not allow air-flow to enter cabinet 6 through wind guide channel 3.This windproof anti-filling device 2 can adopt the structure of unidirectional valve and so on, gets final product with the demand that satisfies above-mentioned windproof anti-filling.
In the present embodiment, the openend of main air inlet 5 vertically arranges down on the main wind inlet channel 8.Main air inlet 5 end faces of main wind inlet channel 8 down prolong, and can fully prevent the wind and rain suction.
Further, can also around cabinet 6, reach the top and adopt heat-insulating fire-proofing material, to improve its adaptability.
Further, can also be provided with the sand-proof net at main air inlet 5 and auxiliary air inlet 9 places, to improve its sand prevention ability.
Further, corner structural design camber or the oblique angle form in each air channel can be reduced windage, improve the water conservancy diversion effect.
During work, the cold air outside the cabinet enters from the air inlet of main wind inlet channel 8, through the independent ventiduct of photovoltaic inversion unit 7 internal power unit, after cooling off the power cell in its air channel, enter the wind guide channel 3 in the lamina tecti assembly 1, through behind the windproof anti-filling device 2, discharge from air outlet 4.
Simultaneously, the outer cold air of cabinet enters from more than one auxiliary wind inlet channel 10, through the independent ventiduct of other non-power unit components in the photovoltaic inversion unit 7, cool off the device in its air channel after, enter in the lamina tecti assembly 1 corresponding with it wind guide channel 3, through behind the windproof anti-filling device 2, discharge from air outlet 4.
By above structure, the photovoltaic inversion unit 7 that air requirement is large, wind speed is high includes power cell from main wind inlet channel 8 air intakes independently, thereby the intake of all the other auxiliary wind inlet channels 10 is reduced, wind speed reduces a lot, the size of auxiliary like this wind inlet channel 10, size can reduce a lot, have effectively improved the sand-proof of whole cabinet 6, the effect of rainwater-proof.Simultaneously, several wind guide channels 3 in the lid housing 11 are separate, and cooled air-out does not interfere with each other.
As shown in Figure 2, be concrete application example 2 of the present utility model, just be with the difference of concrete application example 1: cabinet 6 interior left and right two the photovoltaic inversion units 7 of having arranged, so external main wind inlet channel 8 is also corresponding left and rightly respectively to arrange one, the wind guide channel 3 in the lid housing 11 also corresponding increase from the air-out of middle two ends.
Below only be preferred implementation of the present utility model, protection range of the present utility model also not only is confined to above-described embodiment, and all technical schemes that belongs under the utility model thinking all belong to protection range of the present utility model.Should be pointed out that for those skilled in the art the some improvements and modifications not breaking away under the utility model principle prerequisite should be considered as protection range of the present utility model.
