The heat radiation structure comprises an IGBT module radiator arranged on the top of a cabinet of the photovoltaic inverter. A forward centrifugal fan module is arranged below the IGBT module radiator, and is communicated with the IGBT module radiator through an air duct. An electric reactor is arranged at a middle position of the bottom of the cabinet of the photovoltaic inverter, and air inlets are arranged on the front and back sides of the bottom of the cabinet of the photovoltaic inverter. The photovoltaic inverter is advantaged by high power density, modularization, simple and compact structure, high heat radiation efficiency and low heat radiation cost.
Description
Technical field
The utility model relates to photovoltaic DC-to-AC converter technical field, is specifically related to a kind of radiating 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 radiating structure of photovoltaic DC-to-AC converter, and its complete machine has advantages of that power density is high, modularization, simple and compact for structure, 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 radiating structure of photovoltaic DC-to-AC converter, comprise the IGBT module heat radiator 1 that is placed in photovoltaic DC-to-AC converter enclosure top, forward centrifugal blower fan module 2 is placed in IGBT module heat radiator 1 below and is communicated with it by guide duct, reactor 3 is placed in middle position, photovoltaic DC-to-AC converter rack bottom, and before and after photovoltaic DC-to-AC converter rack bottom, both sides have air inlet 4.
Described forward centrifugal blower fan module 2 comprises horizontally disposed two forward centrifugal blower fans.
Described air inlet 4 is provided with Air Filter.
Compared to the prior art, tool has the following advantages the utility model:
1) single rack is both integrated IGBT modular structure assembly, simultaneously also integrated reactor, makes unit compact conformation, and power density effectively improves, and in addition, modularized design makes product maintenance convenient, has stronger competitiveness in industry.
2) heat radiation of whole rack has only adopted lower-cost two forward centrifugal blower fans, is not to need Side plate of machine cabinet, compact conformation, and simple and convenient many inverter parallel operation of framework, have saved a large amount of material costs;
3) complete machine air channel adopts bottom in and top out, before and after rack, the cold air of both sides is under fluid inertia force effect, strengthened the heat radiation of reactor, again under fluid negative-pressure power and buoyancy lift effect, air is after forward direction centrifugal blower accelerates, form high-speed air flow, the heat radiation of strengthening IGBT module, effectively improves complete machine radiating efficiency.
Accompanying drawing explanation
Accompanying drawing is the radiating 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 radiating structure of a kind of photovoltaic DC-to-AC converter of the utility model, comprise the IGBT module heat radiator 1 that is placed in photovoltaic DC-to-AC converter enclosure top, forward centrifugal blower fan module 2 is placed in IGBT module heat radiator 1 below and is communicated with it by guide duct, reactor 3 is placed in middle position, photovoltaic DC-to-AC converter rack bottom, and before and after photovoltaic DC-to-AC converter rack bottom, both sides have air inlet 4.
As preferred implementation of the present utility model, described forward centrifugal blower fan module 2 comprises horizontally disposed two forward centrifugal blower fans.Not not so just to need Side plate of machine cabinet, compact conformation, simple and convenient many inverter parallel operation of framework, have saved a large amount of material costs.
As preferred implementation of the present utility model, described air inlet 4 is provided with Air Filter.Prevent that dust from entering rack.
Operation principle of the present utility model is: cold wind enters rack from the air inlet 4 of both sides, front and back, rack bottom, under fluid inertia force effect, first cooling reactor 3, again under fluid negative-pressure power and buoyancy lift effect, enter forward centrifugal blower fan module 2, after forward direction centrifugal blower module 2 CENTRIFUGAL ACCELERATING, high-speed air flow enters the fin channels of IGBT module heat radiator 1, take away the heat of IGBT module, finally from the air outlet of enclosure top, flow out.
