Abstract
Abstract A radiator assembly for a locomotive is provided. The locomotive has an engine for driving the locomotive and a cooling water system for circulating cooling water through the engine to operatively control the temperature of the engine, the assembly including a radiator in fluid communication with the cooling system and a fan which selectively draws air through the radiator and into the inlet of the fan. The radiator assembly also includes a shutter for selectively controlling the drawn air flow through the radiator and a control system operatively attached to the shutter for actuating the shutter to control the drawn air flow in dependence on a determined control temperature. The control assembly is also operatively attached to the fan to select and set the speed of the fan in dependence on the determined control temperature.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
188 words
A radiator assembly for an engine having a cooling water system for circulating cooling water through the engine to operatively control the temperature of the engine, the assembly including: a radiator in fluid communication with the cooling system; a fan means, including a motor for driving said fan means, for selectively drawing air through the radiator and into the inlet of the fan means; a shutter means for selectively controlling the drawn air flow through the radiator; a motor shield for shielding the motor from relatively hot air exiting from the shutter means; air ducts situated about the motor for supplying relatively cool air to cool the motor; and control means comprising an engine control computer responsive to a water temperature sensor, an ambient air temperature sensor and an oil temperature sensor, the control means being operatively attached to the shutter means for actuating the shutter means to control the drawn air flow in dependence on a determined control temperature, the control means including means operatively attached to the fan means for selecting and setting the speed of the fan means in dependence on the determined control temperature.
Claim 2
Dependent Claim
188 words
A radiator assembly for an engine having a cooling water system for circulating cooling water through the engine to operatively control the temperature of the engine, the assembly including: a radiator in fluid communication with the cooling system; a fan means, including a motor for driving said fan means, for selectively drawing air through the radiator and into the inlet of the fan means; a shutter means for selectively controlling the drawn air flow through the radiator; a motor shield for shielding the motor from relatively hot air exiting from the shutter means; air ducts situated about the motor for supplying relatively cool air to cool the motor; and control means comprising an engine control computer responsive to a water temperature sensor, an ambient air temperature sensor and an oil temperature sensor, the control means being operatively attached to the shutter means for actuating the shutter means to control the drawn air flow in dependence on a determined control temperature, the control means including means operatively attached to the fan means for selecting and setting the speed of the fan means in dependence on the determined control temperature.
Claim 3
Dependent Claim
18 words
The assembly of claim 1 wherein the shutter means is disposed between the radiator means and fan means.
Claim 4
Dependent Claim
38 words
The assembly of claim 1 wherein the control means includes means for selecting a first control temperature level for comparison to the determined control temperature level in dependence on whether the determined control temperature is increasing or decreasing.
Claim 5
Dependent Claim
25 words
The assembly of claim 1 wherein the radiator is horizontally extending, and said motor shield is disposed between the fan means and the radiator means.
Claim 6
Dependent Claim
44 words
The assembly of claim 4 wherein the radiator assembly includes an air shield vertically extending about the sides of the radiator, and said air ducts extend generally horizontally from the base of the motor through the air shield for providing air to the motor.
Claim 7
Dependent Claim
40 words
The assembly of claim 1 wherein the radiator is generally flat and has two pairs of opposing sides, and the radiator includes at least one inlet and at least one outlet, the inlet being disposed diagonally across from the outlet.
Claim 8
Dependent Claim
34 words
The assembly of claim 6 wherein the pairs of sides of the radiator form a four sided parallelogram, one of the pair of opposing sides being offset to the other pair of opposing sides.
Claim 9
Dependent Claim
25 words
The assembly of claim 1 wherein the control means includes means for cycling the shutter means in dependence on the temperature of the ambient air.
Claim 10
Dependent Claim
23 words
The assembly of claim 1 wherein the control means includes means for cycling the shutter means in dependence on the determined control temperature.
