Abstract
A roof structure for a power module of a locomotive is disclosed. The roof structure may have an upper roof layer and at least a portion of the upper roof layer may have a first set of cooling passages. The roof structure may further have a lower roof layer at least partially positioned below the upper roof layer and at least a portion of the lower roof layer may have a second set of cooling passages. Each of the cooling passages of the first set of cooling passages may not overlap a cooling passage of second set of cooling passages.
Claims20
A roof structure for a power module of a locomotive, the roof structure comprising:
- an upper roof layer, at least a portion of the upper roof layer including a first set of cooling passages;
- and
- a lower roof layer at least partially positioned below the upper roof layer, at least a portion of the lower roof layer including a second set of cooling passages, wherein each of the cooling passages of the first set of cooling passages does not overlap a cooling passage of second set of cooling passages.
A method of cooling a power module for a locomotive, the power module having a plurality of walls and a roof structure, the method comprising:
- allowing a flow of cooling air to pass through at least a portion of at least one of the plurality of walls;
- directing the flow of cooling air over at least a portion of the power module;
- expelling the flow of cooling air through the roof structure, such that the flow of cooling air passes through a lower roof layer via a first set of cooling passages and through an upper roof layer via a second set of cooling passages;
- and
- collecting a majority of environmental elements that pass through the second set of cooling passages, such that the majority of environmental elements are prevented from passing through the roof structure into the power module.
A power module for a locomotive, the power module comprising:
- a frame;
- a generator set supported by the frame;
- an enclosure covering the frame and including a plurality of walls and a roof structure, the roof structure comprising:
- a first roof section including a plurality of cooling passages configured to expel heat generated by the power system through the first roof section and limiting environmental elements from entering the power module through the first roof section;
- and
- a second roof section removeably positioned adjacent the first roof section and including a solid surface.
