Description

technical field [0001] The invention relates to the technical field of heating IGBT modules, in particular to an online heating device for IGBT modules. Background technique [0002] With the rise of new energy vehicles, IGBT modules, as the core components of vehicle drives, have increasingly stringent testing requirements. The temperature rise simulation in the test not only requires high parameters, but also requires better automation integration of heating equipment. [0003] The traditional IGBT module heating device mostly uses a single oven or a tunnel type chain plate heating furnace. The former is integrated in the automatic production line, which needs to be equipped with complicated manipulators or robots, and repeatedly opens the door, uploads and downloads heating in a single piece, which has low efficiency and large investment; the latter often occupies a large area due to the plate chain structure and air transmission efficiency, and can High consumption and ...
