Abstract

The utility model discloses a radiating structure of a cast photovoltaic inverter box body. The radiating structure comprises a radiation fin, a fan, a component and an air duct system, wherein the radiation fin is arranged on one side of the box body, the air duct system is connected below the radiation fin, and the fan is arranged below one end of the air duct system. The radiating structure has simple structure and convenience in use, the radiation fin is designed to be in arc shape transition and extend leftwards and rightwards, and an upper surface of the radiation fin is of a V shape, thus the radiation area is added, the danger that rainfalls directly pour onto the fan is avoided, and the wind resistance of the overall radiation system is lowered, additionally, a temperature of the radiation fin is enabled to be more uniform under the driving of air current of the fan from bottom to top, radiation effect is excellent, and the service life of the photovoltaic inverter box body is more effectively prolonged.

Description

The photovoltaic DC-to-AC converter casing radiator structure of die casting
Technical field
The utility model relates to a kind of photovoltaic DC-to-AC converter casing radiator structure, relates in particular to a kind of photovoltaic DC-to-AC converter casing radiator structure of die casting.
Background technology
Photovoltaic DC-to-AC converter is a photovoltaic generating system core power regulating element, occupies the system cost ratio at 10%-15%, and higher technology content is arranged.The electronic devices and components of photovoltaic DC-to-AC converter all are encapsulated in the inverter casing; Can play the effect of firm and protection component; But components and parts are encapsulated in the narrow space; Problem shows especially out thereupon, and the subject matter of inverter casing existence at present is to guarantee the heat radiation of components and parts in the casing and the IP degree of protection of casing, and then components and parts are caused damage.Radiating mode commonly used at present is to add radiator fan casing to be dispelled the heat with the heat radiation wing in the casing outside, in order to meet the principle that thermal current flows from the bottom up, is placed on heat radiation wing bottom to fan usually; The wind that lets fan blow out flows from the bottom up; So just need to solve the fan waterproof problem, drench on the fan along radiating fin, normally on vertical radiating fin, cross out a fin in order to stop rainwater; But this lets meeting hinder the discharge of hot-air, causes radiating effect bad.
The utility model content
The utility model provides a kind of photovoltaic DC-to-AC converter casing radiator structure of die casting to above-mentioned deficiency, and purpose is: a kind of good heat dissipation effect is provided, fan is had a photovoltaic DC-to-AC converter casing of the aluminium alloy compression casting of water-proof function simultaneously.
The technical solution of the utility model:
A kind of photovoltaic DC-to-AC converter casing radiator structure of die casting; Comprise radiating fin, fan, components and parts, ducting system; It is characterized in that: said casing simultaneously is provided with radiating fin, and the radiating fin below is connected with ducting system, and ducting system one end below is equipped with fan.
Said ducting system is made up of two muscle, peripheral frame and independent air channel cover plates in air channel that form with casing die casting.
The said radiating fin curved from the bottom up transition in bottom is stretched to the left and right sides, and the upper surface forming V-shape.
The quantity of said ducting system is at least one.
Said number of fans is at least one.
Said two distances with the muscle of casing formation from bottom to top enlarge gradually, and original position is positioned at the front end of fan, and final position and two radiating fins join, and can connect the radiating fin of diverse location with the difference of casing radiating fin high temperature concentrated position.
Said photovoltaic DC-to-AC converter casing is to be formed by aluminium alloy compression casting.
Said air channel cover plate is close to two muscle and air channel external surrounding frame.
The beneficial effect of the utility model
The utility model is simple in structure, and arc-shaped transition and two ends stretching, extension to the left and right and upper surface forming V-shape are arranged to radiating fin in the use aspect; So not only increased area of dissipation but also had and prevented that rainwater from directly drenching the danger on fan; Thereby also reduced the windage of entire heat dissipation system, in addition through fan airstream from down and on drive under, make heatsink temperature more even; Good heat dissipation effect has more effectively prolonged photovoltaic DC-to-AC converter casing useful life.

Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the utility model radiating fin.
Fig. 3 is the utility model air channel cover plate scheme of installation.
Wherein: 1, radiating fin; 2, fan; 3, muscle; 4, frame; 5, air channel cover plate; 6, casing.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further description.
To shown in Figure 3, the photovoltaic DC-to-AC converter casing radiator structure of a kind of die casting of the utility model comprises radiating fin 1 like Fig. 1; The curved from the bottom up transition in radiating fin 1 bottom is stretched to the left and right sides, and the top forming V-shape, fan 2, components and parts, ducting system; Ducting system is made up of two muscle 3, peripheral frame 4 and independent air channel cover plates 5 in air channel that form with casing die casting, is provided with radiating fin 1 in casing 6 one sides, and radiating fin 1 below is connected with ducting system; Ducting system one end below is equipped with 2, two distances with the muscle 3 of casing formation of fan and from bottom to top enlarges gradually, and original position is positioned at the front end of fan 2; Final position and two radiating fins 1 join; The radiating fin 1 that can connect diverse location with the difference of casing radiating fin 1 high temperature concentrated position, air channel cover plate 5 are close to two muscle 3 and air channel external surrounding frame 4, and the quantity of said ducting system is at least one; The quantity of fan 2 is at least one, and said photovoltaic DC-to-AC converter casing 6 is to be formed by aluminium alloy compression casting.
The concrete course of work:
The heat that produces in the components and parts course of work in the photovoltaic DC-to-AC converter casing 6 is equipped with fan 2 through ducting system one end below; Fan 2 is directly dried to radiating fin 1 through ducting system; The air-flow that blows out along the fin 1 of arc-shaped transition from the right and left air-out; Form convection current with cool exterior air, casing 6 radiating fins 1 are formed better heat radiating effect.In addition; When rainwater vertically falls; Can drench at upper surface to become on the radiating fin 1 of " V " shape, current are concentrated from upper surface " V " shape radiating fin 1 low side and are flowed out then, and cover plate 5 back sides are wandered on the ground along the air channel then; Current can directly not wandered on the fan 2, therefore fan 2 are had the rainproof effect of good dash.
