In view of this, the utility model is intended to propose a kind of high frequency switch power power unit box, can overcome deficiency of the prior art, ensures that power cell normally runs.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of high frequency switch power power unit box, comprises the casing with chamber door, is provided with the device installation portion of multiple vertical layout in described casing on cabinet wall, and each device installation portion interval is arranged, and is also provided with blower fan at the top of described casing.
Further, described device installation portion comprises the wiring board installation portion that the wiring board for the formation of power cell control module is installed, and the IGBT module installation portion that the IGBT module for forming high-frequency inverter circuit is installed.
Further, in described casing, be fixed with the dividing plate vertically arranged, be formed with gap between described dividing plate and casing top, described wiring board installation portion is located on dividing plate.
Further, described device installation portion comprises multiple insulation connection seats that are triangular in shape or rectangular arrangement.
Further, be provided with air inlet in the bottom of described casing, described air inlet comprises the slotted eye that multiple tracks is arranged side by side.
Further, described air inlet is provided with screen pack.
Further, in described casing, casing buttress brace is provided with.
Relative to prior art, the utility model has following advantage:
High frequency switch power power unit box of the present utility model is by the vertical layout of device installation portion, and blower fan is set at casing top, what blower fan can be made to produce distinguished and admirablely flows more smoothly between each device, dust is avoided to adhere on device, and the dust on device is taken away by distinguished and admirable, the problem causing power cell operational failure because of dust attachment can be solved thus.Device installation portion adopts insulation connection seat can ensure the reliable setting of device at casing body.Air inlet is multiple slotted eyes be arranged side by side, and can make the distinguished and admirable comparatively even of each device place in casing, to ensure cooling to each device and cleaning effect.The structural strength that buttress brace also can strengthen casing is set in casing.
