Antenna plate cold conduction plate, millimeter wave radar cold conduction structure and temperature field simulation method thereof

The invention discloses an antenna board cold conduction board, which belongs to the field of radar, and comprises a cold conduction board body, one side surface of the cold conduction board body is provided with a heat conduction groove matched with the shape of an antenna PCB, and the other side surface of the cold conduction board body is provided with a plurality of ribs for increasing heat capacity. A heat dissipation channel is arranged between every two adjacent ribs, the antenna PCB is provided with a concentrated heat source area, one part of every two adjacent ribs is close to the concentrated heat source area to form a low-voltage area, and the other part of every two adjacent ribs is far away from the concentrated heat source area to form a high-voltage area. And cold air in the high-voltage area is blown to the low-voltage area along the heat dissipation channel. The invention also discloses a millimeter wave radar cold conduction structure and a temperature field simulation method, the antenna b
