The invention belongs to the field of automobiles, and discloses a vehicle windshield defrosting system utilizing automobile tail gas waste heat. The system comprises an electromagnetic valve, a maincontrol chip, a centrifugal fan and a vehicle-mounted storage battery, and the electromagnetic valve, the main control chip and the centrifugal fan are all powered by the vehicle-mounted storage battery; the electromagnetic valve is a two-position three-way pneumatic electromagnetic valve, the coil control end of the electromagnetic valve is connected with the output end of the main control chip,the electromagnetic valve is provided with an air inlet, an air outlet and an air exhaust mouth, the air inlet and the air exhaust mouth of the electromagnetic valve both communicate with an automobile exhaust pipeline, the air exhaust mouth is in a normally open state when the electromagnetic valve is closed, and the air outlet of the electromagnetic valve is connected with the centrifugal fan; and the vehicle-mounted storage battery is connected with the centrifugal fan through an electronic switch S1, and the electronic switch S1 is connected with a manual switch of a control panel in the automobile. Tail gas is led to the centrifugal fan through the electromagnetic valve and the electromagnetic valve control circuit, effective defrosting can be conducted on the front windshield by spraying out gas through the centrifugal fan, tail gas utilization can be achieved, and low-cost defrosting can also be achieved.

    本发明属于汽车领域,公开了一种利用汽车尾气余热的车辆挡风玻璃除霜系统,包括电磁阀、主控芯片、离心风机和车载蓄电池,所述电磁阀、主控芯片和离心风机均由车载蓄电池供电;所述电磁阀为两位三通气动电磁阀,电磁阀的线圈控制端连接主控芯片的输出端,电磁阀设有进气口、出气口和排气口,电磁阀的进气口和排气口均与汽车排气管道连通,电磁阀关闭时排气口为常开状态,电磁阀的出气口连接离心风机;车载蓄电池经电子开关S1后连接离心风机,电子开关S1连接汽车内控制面板的手动开关。本发明通过电磁阀和电磁阀控制电路将尾气引至离心风机,通过离心风机喷出气体即可对前挡风玻璃进行有效除霜,既能实现尾气利用,又能低成本除霜。
