FIELD OF THE DISCLOSURE
[0001] The present invention relates generally to the field of thermal management systems for passenger transport vehicles, and more particularly to a thermal management system for a sleeper coach bus having a rear engine compartment.
BACKGROUND OF THE INVENTION

[0002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
[0003] In existing rear-engine sleeper coach buses, the rearmost passenger berth(s) are subjected to significant , Claims:I/We claim,
1. A thermal management system (100) for a sleeper coach bus having a rear engine compartment (108), the system comprising:
a passive enclosed cool air ducting arrangement (102) configured to minimize heat transfer from the engine compartment (108) to the rear passenger berth mattress (106),
wherein the system includes at least one closed steel air duct (104) extending along a bottom surface of at least one rear berth (106), and at least one closed steel air duct (104) extending vertically along a rear wall of a berth section facing the sun heat,
and wherein the closed steel air duct (104) are sealed, non-ventilated, air recirculating steel air channels forming a conduction-based thermal barrier between the engine compartment (108) and the rear passenger berth mattress without airflow communication.
2. The thermal management system (100) for a sleeper coach bus as claimed in claim 1, wherein the closed steel air duct (104) act as a low-temperature buffer layer that reduces conductive and convect
