Title:
TRACTION CONVERTER COOLING SYSTEM BASED ON BOILING HEAT TRANSFER
Document Type and Number:
WIPO Patent Application WO/2021/223424
Kind Code:
A1
Abstract:
A traction converter cooling system based on boiling heat transfer. The traction converter cooling system comprises a pump (1), a main loop flow adjusting device (2), a filter (4), a cold plate (8), a pressure stabilizing box (11), a condenser flow adjusting device (12), a condenser (14), and a monitoring device etc.. An outlet of the pump (1) is communicated with an inlet of the cold plate (8) by means of a cold plate inlet main pipeline (5); the filter (4) is provided on the cold plate inlet main pipeline (5); the main loop flow adjusting device (2) is provided between the pump (1) and the filter (4); an outlet of the cold plate (8) is communicated with the pressure stabilizing box (11) by means of a cold plate outlet main pipeline (10); the pressure stabilizing box (11) is communicated with an inlet of the condenser (14) by means of a condenser inlet pipeline (13); the condenser flow adjusting device (12) is provided on the condenser inlet pipeline (13); and an outlet of the condenser (14) is communicated with the inlet of the pump (1) by means of a condenser outlet pipeline (16). The traction converter cooling system has the advantages of being high in heat transfer efficiency, high in heat transfer capacity, compact in structure, low in noise and power consumption, simple in structure and the like.
