矢印の如く外部に排出される。 Next, the radiator cooling water temperature reaches the specified temperature (80
℃), the temperature switch 16 closes, the current from the battery 17 flows to the electromagnetic valve 18 and the valve 18 closes, and air from the air pump 19 no longer flows into the hollow shaft 12 and no longer blows out from the hole 12a. The rotation of the hollow shaft 13 in the direction of winding up the shutter 2 is stopped. Therefore, the torsional force of the torsion coil spring 14 causes the hollow shaft 9 to rotate in a direction that involves the shutter 2, so that the front surface of the radiator 1 is opened. Also, as mentioned above, hole 1
When the hollow shaft 13 is rotated, the air blows out from the blade 2 at the lower part of the hollow shaft 13.
1 and is fed into the hollow shaft 12 from the hole 20,
It is discharged to the outside as shown by the arrow.
