Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Please referring to Fig. 1 to Fig. 7, the radiator structure 100 of the four-quadrant frequency converter that first embodiment of the present utility model provides comprises: box frame 110, be arranged on mounting panel 120, the switching tube 130 that is installed in mounting panel 120 1 sides, the radiator 140 that is installed in mounting panel 120 opposite sides and fan group 150 in the box frame 110.
The heat that produces during switching tube 130 work is delivered on the radiator 140 and at radiator 140 conducts, with even distribution.After radiator 140 carried out heat exchange with the cold wind that enters from air intake vent 112, temperature reduced, and continued to absorb the heat that passes over from switching tube 130, thereby assurance switching tube 130 is worked in normal temperature range.Under the swabbing action of fan group 150, discharge box frame 110 from air outlet 114 through the heated hot blast in radiator 140 backs.
Please referring to Fig. 8 to Figure 14, the radiator structure of the four-quadrant frequency converter that first embodiment of the present utility model provides comprises: box frame 210, be arranged on mounting panel 220 in the box frame 210, be installed in mounting panel 220 1 sides switching tube 230, be installed in the radiator 240,260 and fan group 250 of mounting panel 220 opposite sides.
The heat that produces during 230 work of inverse switch pipe is delivered on the radiator 240 and at radiator 240 conducts, with even distribution.After radiator 240 carried out heat exchange with the cold wind that enters from air intake vent 212, temperature reduced, and continued to absorb the heat that passes over from inverse switch pipe 230, thereby assurance inverse switch pipe 230 is worked in normal temperature range.Under the swabbing action of fan group 250, discharge box frames 210 from division board 270 belows process and from air outlet 214 through the heated hot blast in radiator 240 backs.The heat that produces during 230 work of rectifier switch pipe is delivered on the radiator 260 and at radiator 260 conducts, with even distribution.After radiator 260 carried out heat exchange with the cold wind that enters from side direction air intake vent 216, temperature reduced, and continued to absorb the heat that passes over from rectifier switch pipe 230, thereby assurance rectifier switch pipe 230 is worked in normal temperature range.Under the swabbing action of fan group 250, directly discharge box frame 210 from air outlet 214 through the heated hot blast in radiator 260 backs.
