<p>A cooling system for an auxiliary filtering cabinet of a locomotive comprises a vehicle body (1) and an auxiliary filtering cabinet (2) disposed in the vehicle body (1). The auxiliary filtering cabinet (2) comprises a cabinet body (20), a mechanical device and a ventilation apparatus (5) disposed in the cabinet body (20). The lower portion of the cabinet body (20) is disposed with an air inlet (21), the upper portion thereof is disposed with an inner vehicle air outlet (22), and the top portion thereof is disposed with an outer vehicle air outlet (23); the top portion of the vehicle body (1) is disposed with a discharge opening (11) in communication with the outside, the outer vehicle air outlet (23) and the discharge opening (11) are connected through an air cylinder (3), the extra-vehicle air outlet (23) and the discharge opening (11) are switched into conduction through a valve (4), and the inner vehicle air outlet (22) is opened or closed through a windshield door (6); a controller controls the valve (4) and the windshield door (6) according to the temperature in the vehicle body (1) to operate so that the outer vehicle air outlet (23) and the discharge opening (11) are switched into conduction and at the same time the windshield door (6) closes the inner vehicle air outlet (22), or the outer vehicle air outlet (23) and the discharge opening (11) are isolated and at the same time the windshield door (6) opens the intra-vehicle air outlet (22). The cooling system for an auxiliary filtering cabinet of a locomotive can switch the ventilation system according to the environmental temperature, regulate the temperature of the mechanical device inside the auxiliary filtering cabinet of the locomotive, and ensure that the mechanical device runs stably and reliably.</p> |
