Embodiment Construction
[0046] By way of the above drawings, specific embodiments of the invention have been shown and will be described in more detail hereinafter. These drawings and written descriptions are not intended to limit the scope of the inventive concept in any way, but to illustrate the inventive concept for those skilled in the art by referring to specific embodiments.
[0047]An embodiment of the present invention provides a thermal management system for a vehicle-mounted converter, which adopts the idea of active thermal management, and creates a more comfortable working temperature environment for IGBT devices through a more reasonable water temperature control strategy and a more precise temperature sensor. Long-term work at the temperature of the radiator substrate is about 40°C, avoiding the long-term operation of the IGBT in a wide thermal cycle, thereby greatly improving the reliability of the on-board converter, and can also provide the performance of the IGBT device for the he...
