AI Technical Summary

Benefits of technology

The present patent provides a system for cooling a power generation system of a locomotive using an alternator and an engine system. The system includes a fan for cooling both the alternator and the engine system. The system also includes sensing modules to determine the temperature of the alternator and the engine system, and a controller that regulates the air flow based on the temperature readings. The technical effect of this system is to improve the cooling efficiency of the power generation system, which can help to increase the reliability and durability of the system.

Problems solved by technology

When the heat generated by these components reach their respective thermal limits, the components can start malfunctioning or a complete breakdown / failure of the component eventually takes place.
The use of components generating less heat is both costlier and demanding as it requires regularly replacing / updating systems for changes in power requirement.
The secondary cooling systems improve the overall cooling while affecting the overall efficiency of the machine.

Embodiment Construction

[0012]Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0013]FIG. 1 illustrates a machine 100. In an embodiment, the machine 100 is a locomotive. The locomotive 100 may include diesel-fueled electric locomotive or dual-fueled electric locomotive. The locomotive 100 may include single locomotive, multiple locomotives, a train moved by single locomotive, a train moved by multiple locomotives and any other arrangement of locomotives. As shown in FIG. 1, the locomotive 100 may include a system for cooling 102 (not shown). The locomotive 100 may further include first compartment 104, a fan 106 positioned in the first compartment 104, a power compartment 108, a power generation system 110, one or more wheels 112, one or more traction motors 114, and a controller 116. The fan 106 may provid...

Abstract

A system for cooling a power generation system of a locomotive. The power generation system includes an alternator and an engine system. The alternator is coupled to the engine system. The engine system comprises one or more components. The system includes a fan providing air flow, a first sensing module to determine a first temperature of the alternator, a second sensing module to determine a second temperature of the one or more components of the engine system, and a controller. The controller regulates the air flow based on the first temperature and the second temperature.

Description

TECHNICAL FIELD[0001]The present disclosure relates generally to the field of locomotives. In particular, the present disclosure relates to a system for cooling components of a locomotive.BACKGROUND[0002]Machines have several components generating heat during their operation. The components may include engine systems, alternators and auxiliary motors driving fan(s) / blower(s). When the heat generated by these components reach their respective thermal limits, the components can start malfunctioning or a complete breakdown / failure of the component eventually takes place.[0003]The heat generated must be regulated by either using components generating less heat and / or by making heat dissipation more effective. The use of components generating less heat is both costlier and demanding as it requires regularly replacing / updating systems for changes in power requirement. In general, primary cooling systems having a radiator type arrangement are used to dissipate heat being generated by the c...
