Abstract

An evaporative cooling system for a radiator and method for retrofitting an existing radiator with an evaporative cooling system is provided. The cooling system includes at least one spray nozzle configured to be connected to the radiator upstream of a radiator core and configured to distribute a mist of water to the radiator core; a water source configured to hold water for conveyance to the at least one spray nozzle; and a conduit assembly for conveying water from the water source to the at least one spray nozzle. The evaporative cooling system provides a quick and inexpensive solution for cooling radiators in situations where short-term extreme temperature events occur.

First claim

The invention claimed is:

1. An evaporative cooling system for a radiator, the cooling system comprising:
at least one spray nozzle associated with the radiator and configured to distribute a mist of water to the radiator;
a water source configured to hold water for conveyance to the at least one spray nozzle; and
a conduit assembly for conveying water from the water source to the at least one spray nozzle, wherein the radiator includes a radiator core and the at least one spray nozzle is configured to distribute the mist of water to the radiator core, the radiator includes a fan for causing air to flow across the radiator core and wherein the at least one spray nozzle is positioned upstream from the fan, and the at least one spray nozzle is secured to a fan guard provided on the radiator.

2. The cooling system of claim 1 , wherein the at least one spray nozzle comprises a plurality of spray nozzles.

3. The cooling system of claim 2 , wherein the plurality of spray nozzles comprises at least six spray nozzles arranged in spaced relation with respect to each other.

4. The cooling system of claim 2 , wherein the plurality of nozzles are associated with the conduit assembly and in fluid communication with each other and wherein the plurality of nozzles are mounted in a circular arrangement.

5. The cooling system of claim 1 , wherein the at least one spray nozzle comprises a plurality of spray nozzles and the plurality of spray nozzles are secured to the fan guard at spaced relation with respect to each other.

6. The cooling system of claim 1 , including at least one thermocouple for monitoring the temperature of the radiator.

7. The cooling system of claim 6 , wherein the at least one thermocouple comprises a plurality of thermocouples including at least one thermocouple associated with the water entering a radiator core and at least one thermocouple associated with the water exiting the radiator core.

8. The cooling system of claim 1 , including a humidity sensor associated with the radiator.

9. The cooling system of claim 1 , wherein the at least one spray nozzle comprises six spray nozzles and wherein a flow rate of water through each of the spray nozzles is approximately 2.53 gallons per hour.

10. The cooling system of claim 1 , wherein the radiator with the cooling system has an increase of approximately 12%-13% in cooling effectiveness when compared to a radiator without the cooling system.

11. A method of retrofitting a radiator with an evaporative cooling system, said radiator including a radiator core, a fan, and a fan guard provided on the radiator, the method comprising:
securing at least one spray nozzle to the fan guard provided on the radiator upstream from the fan, the at least one spray nozzle configured to distribute a mist of water to the radiator;
providing a water source configured to hold water for conveyance to the at least one spray nozzle; and
providing a conduit assembly for conveying water from the water source to the at least one spray nozzle.

12. The method of claim 11 , wherein the at least one spray nozzle comprises a plurality of spray nozzles and the conduit assembly is configured for connecting the plurality of spray nozzles together in fluid communication and in spaced relation with respect to each other and wherein the method further includes securing the plurality of spray nozzles and at least a portion of the conduit assembly to the fan guard.

13. The method of claim 12 , wherein the conduit assembly includes a hose and the method includes connecting the hose to the water source and providing at least one adapter for controlling the flow of water between the plurality of spray nozzles.

14. The method of claim 11 , wherein the method comprises securing at least six water nozzles to the fan guard and wherein use of the evaporative cooling system results in a 2° C. drop in a temperature of the radiator and increases the cooling effectiveness of the radiator by approximately 12-13%.

15. A radiator and evaporative cooling system comprising a radiator having a radiator core, a fan, and a fan guard provided on the radiator and an evaporative cooling system comprising a least one spray nozzle and a conduit assembly, wherein the spray nozzle is configured to be secured at a location upstream from the radiator fan and wherein the conduit assembly is configured for conveying water from a water source to the at least one spray nozzle to enable the spray nozzle to distribute a mist of water to the radiator.

16. The system of claim 15 , wherein the at least one spray nozzle comprises a plurality of spray nozzles and wherein the plurality of spray nozzles are configured to be secured to the fan guard.

17. The system of claim 16 , wherein the plurality of spray nozzles comprises at least six nozzles.
