Do you know the harm caused by IGBT module overheating?

Do you know the harm caused by IGBT module overheating? IGBT module itself has a certain power, the module itself will generate heat, the overall performance and reliability of IGBT module are affected by temperature. Design rules are often used to compare failure rate figures.According to the design guidelines, one of the design rules shows that the failure rate will double for every 10℃ rise in temperature when the component is operating in an environment above 65℃.So cooling IGBT module is also extremely important work!

IGBT module is high power semiconductor devices, loss power makes the heat more, combined with the IGBT junction temperature should not exceed 125 ℃, should not be long term work at higher temperatures, usually large current through the IGBT module, switching frequency is higher, leads to the wastage of the IGBT device is big also, if the heat is not spread out in time, make the device junction temperature over 125 ℃, IGBT module should not be long-term work under the critical temperature, the damage is bad IGBT heat sink temperature overheat is IGBT damage to affect the operation of the machine work.IGBT overheat may be the cause of bad driving waveform or current is too large or too high switch frequency, also may be due to poor heat dissipation condition, that in the case of cooling bad this plus the corresponding thermal design scheme of the heat sinkis given priority to with transfer and the temperature of the module to allow faster cooling, the purpose of the heat sink is to increase the cooling area, so that the IGBT power device heat is transferred to the air. LORI heat sink products also include IGBT heat sink, we cooperate with many industry users, to provide them with high quality IGBT heat sink, IGBT water cold plate, IGBT heat pipe heat sink and so on.

If IGBT module heat dissipation is not good and the temperature is too hot, it will directly damage or affect the operation of the whole machine. Come to LORI, we have a professional thermal management engineers can provide you with IGBT accurate thermal countermeasures, let your IGBT module away from the danger of overheating, LORI heat sink has always been committed to the development and production of a variety of high power electronic heat sink including IGBT,  to provide users with better products, better services.
