It can be understood that in the related art, the scheme of using the thermocouple to perform single-side point distribution has single experimental data and certain contingency, and because the heat dissipation rates of the fluids on the two sides of the IGBT shell 11 are different, the experimental data obtained by the scheme cannot accurately represent the overall temperature rise data of the IGBT.
And the utility model provides a IGBT device, owing to the fluid heat dissipation rate who considers 11 both sides of IGBT casing varies, consequently the device has set up first thermocouple 2 respectively and second thermocouple 3 in 11 both sides of IGBT's casing and has carried out the temperature rise and detect, and so, on the one hand, the temperature rise data of 11 both sides of IGBT casing are monitored simultaneously, make the temperature rise data that the experiment obtained more representative, and on the other hand, the data that this device obtained are also not single-point measurement's single data, but a plurality of data of multiple spot measurement, consequently, more the accuracy.
