Abstract:
1. An outside air introduction grill unit for inducting a natural convection in an air influx room of a vehicle, comprising: at least an outside air inlet formed in an inner side of the air influx room and including at least a slot and a protruding portion to partially cover the at least a slot to directly induct air into the air influx room; and at least an outside air outlet formed in the inner side of the air influx room and including a plurality of slots and a protruding portion to partially cover the plurality of slots to directly induct air in the air influx room to the outside so that the air flowing into the air influx room circulates in the air influx room and is discharged by natural convection; wherein the outside air inlets and the outside air outlets are spaced apart from each other; wherein the protruding portion of the at least an outside air inlet and the protruding portion of the at least an outside air outlet are aligned in opposite direction therebetween; and wherein an outside air introduction grill is provided between a compressor and an air tank which receives compressed air generated in the compressor operated in conjunction with an engine through a pipe line, stores the compressed air, and supplies the compressed air to a compressed air using device to constitute a bottom side of an APU room including an air drier which reduces a temperature by a flow of the compressed air and collects and discharges moisture, so that the air is introduced through the outside air inlets into the APU room to induct the natural convection, and then discharged through the outside air outlets to the outside.
