Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
Embodiment one: a kind of three-phase inverter, the radiator fan 11 comprising box body, be arranged at the multiple device in box body and be arranged on box body, wherein, device comprise inverter power device 3 and boost power device 4 are installed power amplifier board 5, exchange export EMI plate 6, direct current exports EMI plate 7, display screen 8, inductance box, inductance box radiator and main radiator 10.
As shown in Figure 3, box body comprises inner box 1 and is arranged at the outter box 2 of inner box 1 side.Inner box 1 and outter box 2 are made up of box body and lid respectively.
As shown in Figure 1, power amplifier board 5, interchange export EMI plate 6, direct current exports EMI plate 7 and display screen 8 is arranged in inner box 1, inverter power device 3 on power amplifier board 5 and boost power device 4 are staggeredly set, and exchange the side that output EMI plate 6, display screen 8 and direct current output EMI plate 7 are set in turn in power amplifier board 5.More preferred scheme is that inner box 1 is divided into upper cavity and lower chamber, and upper cavity and lower chamber are equipped with lid respectively.Power amplifier board 5 is arranged in upper cavity, exchanges output EMI plate 6, display screen 8 and direct current output EMI plate 7 and be arranged in lower chamber.
As shown in Figure 2, inductance box, inductance box radiator and main radiator 10 are arranged in outter box 2, the setting corresponding with power amplifier board 5 of main radiator 10, and inductance box and inductance box radiator 9 are arranged at the side of main radiator 10.Two radiator fans 11 of inverter are arranged at the sidepiece of power amplifier board 5 and main radiator 10, and offer louvre 12 on the both sides sidewall of the outter box 2 corresponding to inductance box and inductance box radiator 9.
Present design Integral Thought is the mentality of designing that inverter inner box 1 separates with outter box 2.Wherein inner box 1 mainly places each PCBA board, and outter box 2 mainly places radiator.Two stage power device is placed by offset, effectively reduces power device working temperature.Inductance box radiator carries out semiclosed design with between inner box 1 by box body itself, reduces inductance box to inner box 1 radiations heat energy, reduces temperature in box body.Perforate on outter box 2 simultaneously about inductance box radiator, accelerates the flowing of inductance box ambient air, reduces inductance box working temperature.The main heating element of inner box 1 is kept at a distance simultaneously, is in staggered distribution, inner box 1 homogeneous temperature is distributed, and solves a too high problem of other places temperature in inner box 1.
