the utility model is to provide a kind of and helps to improve radiating effect and use the function of bringing into play power device ideally and increase the service life, help embodying easy accessibility and use the inverter that reduces dismounting operation intensity.
The task of
the utility model is accomplished like this; A kind of inverter; Comprise inversion unit and the installation base plate that is used to supply to install said inversion unit; Be characterised in that: said inversion unit has several, and is installed in side by side on the said installation base plate with the state of each interval.
in one of the utility model concrete embodiment, described several inversion units respectively comprise a power device and a heat abstractor, and power device is arranged on the heat abstractor, and heat abstractor is fixed on the described installation base plate.
are in another concrete embodiment of the utility model; Described heat abstractor comprises first, second side plate, top board and fan; First, second side plate is fixed on the described installation base plate parallelly, and a side of the length direction of top board and the top of first side plate are fixed, and the top of the opposite side and second side plate is fixed; Fan is fixed between first, second side plate, and the power device of described inversion unit is fixed on the said top board.
in another concrete embodiment of the utility model, described power device is IGBT (insulated gate bipolar transistor).
in another concrete embodiment of the utility model, described installation base plate is provided with a wind channel tube, and this wind channel tube is corresponding to the position of the air outlet of said heat abstractor, and communicates with the air outlet of said fan.
Also having among the concrete embodiment of
the utility model; Described inversion unit have one independently the air channel prop up part; Each inversion unit correspondence separately independently the air channel prop up part; This air channel is propped up part and is installed in corresponding to the position of the air outlet of said heat abstractor and installs on the base plate, and communicates with the air outlet of said fan.
The technical scheme that
the utility model provides is owing to installed inversion unit on the base plate for several modes of installing with each interval are installed on side by side by the integrated structure design in the prior art; Can alleviate the operation intensity in the disassembly process; And can improve the radiating effect of inverter, ensure the job stability of power device and increase the service life.
Description of drawings
Fig. 1 is the example structure figure of the utility model.
Fig. 2 is the installation diagram of Fig. 1.
Fig. 3 is another example structure figure of the utility model.
Embodiment
The technical spirit and the beneficial effect of the utility model can fully be understood in order to make the public in
; The applicant will combine accompanying drawing that the embodiment of the utility model is described in detail below; But the applicant is not the restriction to technical scheme to the description of embodiment, anyly makes form but not the variation of essence all should be regarded as the protection range of the utility model according to the utility model design.
see also Fig. 1 and Fig. 2; Provided one base plate 2 has been installed; Several separate and inversion units 1 that structure is identical are installed on this installation base plate 2, and present embodiment is three inversion units 1, these three inversion unit 1 spaces and installation side by side.On installation base plate 2, also be fixed with a wind channel tube 21, the heat that each inversion unit 1 produces is drawn by this wind channel tube 21.Hence one can see that, because incorporate inversion unit is separated into three independently inversion units 1, because the volume of each independent inversion unit 1 is less, helps making things convenient for I&M, and help improving radiating effect.
aforesaid three inversion units 1 respectively comprise a power device 11 and a heat abstractor 12, and power device 11 is located on the heat abstractor 12.Heat abstractor 12 comprises first, second side plate 121,122, top board 123 and fan 124; First, second side plate 121,122 parallel being fixed on are installed on the base plate 2; One side of the length direction of top board 123 and the top of first side plate 121 are fixed; And the top of the opposite side of length direction and second side plate 122 is fixed, and fan 124 is fixing with first, second side plate 121,122 through fan bearing 1241.Preferably, the card base 12411 of fan bearing 1241 is snapped in the draw-in groove 22 of aforesaid installation base plate 2 (Fig. 2 shows), and fan bearing 1241 is connected with first, second side plate 121,122 through screw, thereby forms the passage that makes progress and blow.This snap fit is simple in structure, and is easy for installation, can realize positive dismounting, helps the replacing and the maintenance of fan 124.Fan 124 adopts the blowing mode, and hot blast is blowed to aforesaid wind channel tube 21, is discharged by wind channel tube 21, and radiating effect is got a promotion.Aforesaid power device 11 is fixed on the top board 123, and power device is IGBT (insulated gate bipolar transistor).
see also Fig. 3, another embodiment of the utility model, aforementioned three inversion units 1 respectively correspondence separately independently the air channel prop up part 3; This air channel is propped up part 3 and is installed in corresponding to the position of the air outlet of said heat abstractor 12 and installs on the base plate 2; And communicate with the air outlet of said fan 124, fan 124 adopts the blowing mode, hot blast is blowed to aforesaid air channel prop up part 3; Propping up part 3 by the air channel discharges; And independent separately air draft between each inversion unit 1, mutually noninterfere makes radiating effect be significantly improved.
In sum; There is weak point in the utility model to high-power photovoltaic DC-to-AC converter inversion unit radiator structure design in present, and a kind of more rational inverter is provided, and traditional integrated inversion unit is divided into three independently inversion unit 1 designs; Promptly three groups of power devices 11 are respectively installed on three separate heat abstractors 12; The heat radiation that can guarantee inverter like this is even, makes the power device 11 can steady operation, and prolongs its useful life; Above-mentioned design also make each independently inversion unit 1 volume reduce, make things convenient for Workshop Production to install
