Cooling system for a sensor cleaning system
View Patent ↗A cooling system is for cooling a sensor cleaning system of a vehicle. the cooling system includes a collector configured to accommodate water, which reaches a windshield of the vehicle, a pump providing a flow force for moving the water accommodated in the collector along a conduit, and a cooling module to which water moving along the conduit flows and which surrounds a cooling target.
1. A cooling system for a sensor cleaning system of a vehicle, the cooling system comprising:
a collector configured to accommodate water which reaches a windshield of the vehicle;
a pump providing a flow force for moving the water accommodated in the collector along a conduit and configured to operate by driving a wiper rotatably mounted on the windshield by a driving shaft, wherein the pump comprises a piston configured to be directly pressed by the wiper;
a cooling module to which water moving along the conduit flows and which surrounds a cooling target; and
a rotating body mounted on the driving shaft, the rotating body being configured to press the piston by rotating the wiper, wherein the rotating body is configured to press the piston or release pressure from the piston by changing a portion or an area of the rotating body contacting the piston.
2. The cooling system of claim 1 , further comprising:
a windshield of a vehicle, wherein the collector is provided on a lower portion of a cowl top cover provided on a lower portion of the windshield.
3. The cooling system of claim 2 , wherein a passage is provided in the cowl top cover to cause upper and lower portions of the cowl top cover to communicate with each other, and wherein the collector is mounted below the passage.
4. The cooling system of claim 3 , wherein the passage has a shape of comb teeth or a shape of a lattice.
5. The cooling system of claim 1 , further comprising:
a windshield of a vehicle, wherein the water is collected in the collector by a wiper rotatably mounted on the windshield.
6. The cooling system of claim 1 , wherein the pump comprises:
a cylinder movably accommodating the piston; and
a spring accommodated in the cylinder to provide a restoring force to the piston.
7. The cooling system of claim 1 , wherein the rotating body is configured to contact the piston and to press the piston or release pressure from the piston by rotating the wiper.
8. The cooling system of claim 7 , wherein the rotating body comprises a protrusion, which protrudes towards the piston and maintains contact with the piston.
9. The cooling system of claim 8 , wherein the protrusion is configured to press the piston or release pressure from the piston by changing a portion or an area of the protrusion contacting the piston.
10. The cooling system of claim 1 , wherein the cooling module comprises:
an inlet connected to the conduit and configured to introduce the water to the cooling module; and
an outlet configured to discharge water that flows in the cooling module.
11. The cooling system of claim 1 , wherein the water is rainwater.
12. The cooling system of claim 1 , wherein the cooling target is a compressor, which provides compressed air that is sprayed onto a sensor of the vehicle.
