PARABOLIC ANTENNA DEVICE WIND GUIDE DEVICE, PARABOLIC ANTENNA DEVICE, AND COOLING METHOD FOR PARABOLIC ANTENNA DEVICE

摘要

To increase the heat dissipation efficiency of a circuit while suppressing the increase in size and weight of a circuit device of a parabolic antenna device.SOLUTION: An air guide device 8 attached to a parabolic antenna device 1 has a guide surface 22. The guide surface 22 is arranged through a gap 20 and a taper back surface 14 of a reflector 5 toward a circuit device mounting portion 12 on the back side of the reflector 5 from the opening edge portion 13a on the front side of the reflector 5 of the parabolic antenna device 1. The gap 20 between the guide surface 22 and the taper back surface 14 constitutes a ventilation passage for introducing wind (cooling air) 21 from the opening edge portion 13a side toward the circuit device mounting portion 12. When the cooling air 21 is blown onto the circuit device 7, the heat dissipation efficiency of the circuit device 7 is improved.SELECTED DRAWING: Figure 3
