Description
Technical field
The utility model relates to photovoltaic DC-to-AC converter technical field, is specifically related to a kind of radiator structure of photovoltaic DC-to-AC converter.
Background technology
The heat radiation of traditional photovoltaic DC-to-AC converter all adopts forced air cooling, as: high power device IGBT modular structure assembly and reactor assembly are separately positioned on and in different cupboards, carry out cooling heat dissipation, complete machine apparent size is large, power density is little, owing to using a plurality of blower fan materials and cabinet body structure part, complete machine Material Cost is raise, thereby cause whole aircraft reliability to reduce (many materials cause), the market competitiveness also declines.
Summary of the invention
The shortcoming existing in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of radiator structure of photovoltaic DC-to-AC converter, and its complete machine has advantages of that power density is high, compact conformation, radiating efficiency is high and heat radiation cost is low.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of radiator structure of photovoltaic DC-to-AC converter, comprise the backward centrifugal blower 1 that is placed in photovoltaic DC-to-AC converter enclosure top rear side, be placed in the IGBT module heat radiator 2 of front side, photovoltaic DC-to-AC converter rack middle part, the rear side vertical baffle of described IGBT module heat radiator 2, two vertical side plates of lower horizontal dividing plate and photovoltaic DC-to-AC converter rack and Rear Door be fixing formation independent ventiduct 3 closely, division board 4 with ventilation via hole is positioned at the downside of IGBT module heat radiator 2 and is horizontally disposed with, at photovoltaic DC-to-AC converter rack downside, be provided with reactor 5, in photovoltaic DC-to-AC converter rack lower front side, be provided with air inlet 6.
Described air inlet 6 is provided with Air Filter.
Compared to the prior art, tool has the following advantages the utility model:
1) heat radiation of whole rack has only adopted a backward centrifugal blower, has both saved heat radiation cost, has also improved whole aircraft reliability simultaneously.
2) complete machine is both integrated IGBT module heat radiator, simultaneously also integrated reactor, makes complete machine radiator structure compact, and complete machine power density improves, and has effectively improved competitiveness in industry.
3) complete machine air channel adopts bottom in and top out, utilizes fluid shunting principle, both IGBT module has been carried out to effective cooling, has also strengthened the heat radiation of reactor under fluid buoyancy lift and fluid inertia force effect simultaneously, effectively improves complete machine radiating efficiency.And air channel is unobstructed, nothing heat is interfered.
Accompanying drawing explanation
Accompanying drawing is the radiator structure schematic diagram of the utility model photovoltaic DC-to-AC converter.
Embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail.
As shown in drawings, the radiator structure of a kind of photovoltaic DC-to-AC converter of the utility model, comprise the backward centrifugal blower 1 that is placed in photovoltaic DC-to-AC converter enclosure top rear side, be placed in the IGBT module heat radiator 2 of front side, photovoltaic DC-to-AC converter rack middle part, the rear side vertical baffle of described IGBT module heat radiator 2, two vertical side plates of lower horizontal dividing plate and photovoltaic DC-to-AC converter rack and Rear Door be fixing formation independent ventiduct 3 closely, division board 4 with ventilation via hole is positioned at the downside of IGBT module heat radiator 2 and is horizontally disposed with, at photovoltaic DC-to-AC converter rack downside, be provided with reactor 5, in photovoltaic DC-to-AC converter rack lower front side, be provided with air inlet 6.
As preferred implementation of the present utility model, described air inlet 6 is provided with Air Filter.Place dust and enter rack.
Operation principle of the present utility model is: cold wind enters rack from the air inlet 6 of rack bottom, part cold air carries out after cooling entering rear side independent ventiduct 3 from the division board 4 with ventilation via hole to reactor 5, another part cold air enters the fin channels of IGBT module heat radiator 2, take away after the heat of IGBT module, enter the independent ventiduct 3 of rack rear side, finally by the backward centrifugal blower 1 of enclosure top, hot-air is retracted to rack outside.
