Vehicle fan shroud de-icing assembly
A vehicle fan shroud de-icing assembly includes a vehicle radiator, a fan shroud installed to the radiator, a fan and a heat providing member. The fan is installed to the fan shroud adjacent to the radiator and is configured to selectively move air between heat transferring fins of the radiator. The heat providing member is attached to one of the radiator and the fan shroud. The heat providing member is positioned and configured to provide heat to the fan shroud and/or radiator in order to melt ice, show and shush retained within the fan shroud or on surfaces of the radiator.
1. A vehicle fan shroud de-icing assembly, comprising:
a vehicle engine;
a vehicle radiator connected to the vehicle engine via coolant hoses that direct coolant to and from the vehicle engine;
a fan shroud installed to the radiator;
a fan installed to the fan shroud and configured to selectively move air between heat transferring fins of the radiator; and
a heat providing member attached to the fan shroud proximate the radiator, the heat providing member providing heat to the fan shroud and an exterior area of the radiator melting ice, snow and slush retained within the fan shroud and on an exterior surface of the radiator, the heat providing member running parallel and separate from the coolant hoses and the radiator.
2. The vehicle fan shroud de-icing assembly according to claim 1 , wherein
the vehicle engine includes coolant passageways connected to the coolant hoses that are connected to the radiator.
3. The vehicle fan shroud de-icing assembly according to claim 2 , wherein
the heat providing member includes a coolant flow pipe connected to the coolant passageways of the vehicle engine, the coolant passageways of the vehicle engine defining the heat source of the heat providing member, with coolant from the vehicle engine flowing through the coolant flow pipe.
4. The vehicle fan shroud de-icing assembly according to claim 3 , wherein
the coolant flow pipe receives coolant directly from the coolant passageways of the vehicle engine.
5. The vehicle fan shroud de-icing assembly according to claim 3 , further comprising
a coolant temperature sensor configured to measure temperature of coolant flowing through the coolant passageways of the vehicle engine;
a control valve located between the engine coolant passageways of the vehicle engine and the coolant flow pipe and being configured to switch between an open state allowing coolant flow from the engine coolant passageway to the coolant flow pipe and a closed state preventing coolant flow from the engine coolant passageway to the coolant flow pipe; and
an electronic controller connected to the coolant temperature sensor and the control valve switching the control valve to the open state in response to predetermined criteria related to the measured coolant temperature.
6. The vehicle fan shroud de-icing assembly according to claim 3 , wherein
the coolant flow pipe includes a plurality of heat exchanging fins extending therefrom.
7. The vehicle fan shroud de-icing assembly according to claim 1 , wherein
the fan installed to the fan shroud defines an airflow direction when operating defining upstream and downstream relative to the airflow direction, and
the heat providing member is installed to the fan shroud downstream of the radiator.
8. The vehicle fan shroud de-icing assembly according to claim 7 , wherein
the heat providing member is installed to the fan shroud below the fan.
9. The vehicle fan shroud de-icing assembly according to claim 7 , wherein
the fan includes fan blades that are at least partially encircled by a portion of the fan shroud, and
the heat providing member is installed to the fan shroud downstream of the fan blades.
10. The vehicle fan shroud de-icing assembly according to claim 7 , wherein
the heat providing member is installed to the fan shroud below the fan blades.
11. The vehicle fan shroud de-icing assembly according to claim 1 , wherein
the heat providing member attached directly to a lower tank portion of the radiator.
12. The vehicle fan shroud de-icing assembly according to claim 11 , wherein
the coolant flow pipe includes a plurality of heat exchanging fins extending therefrom.
13. The vehicle fan shroud de-icing assembly according to claim 1 , wherein
the heat source of the heat providing member is an electric heater within the heat providing member.
14. The vehicle fan shroud de-icing assembly according to claim 13 , wherein
the electric heater is installed to a lower section of the fan shroud below the fan.
15. The vehicle fan shroud de-icing assembly according to claim 13 , further comprising
a coolant temperature sensor configured to measure temperature of coolant flowing through the coolant passageways of the vehicle engine; and
an electronic controller connected to the coolant temperature sensor and the electric heater, the electronic controller being configured to operate the electric heater in response to predetermined criteria related to the measured coolant temperature.
