Reasons for high BYD Qin igbt temperature

1. Poor heat dissipation: due to the irrational design of the radiator or poor contact between the radiator and the IGBT, etc., resulting in the IGBT can not be timely dissipated when working, which caused the over-temperature. For this situation, you can take the redesign of the heat sink or improve the heat sink manufacturing process and other methods to solve.

2. Working environment temperature is too high: in a high-temperature environment, the cooling effect of the IGBT will be greatly reduced, thus causing over-temperature. This needs to improve the working environment of the vehicle, such as increasing vents or strengthening measures such as air conditioning.

3. Over-current or over-voltage: When the IGBT is working, if the current or voltage is too large, it will increase the internal temperature of the IGBT, thus causing over-temperature. This requires checking whether the operating current and voltage of the IGBT are within the normal range, and taking appropriate measures to solve the problem.

4. The quality of the IGBT itself: If the IGBT itself has manufacturing defects or damage, it can also cause over-temperature. This requires inspection and repair of the IGBT, such as replacing the faulty IGBT or repair and other measures.
