WIPO Patent Application WO/2021/157875
Kind Code:
A1
Abstract:
A sub module is disclosed. A sub module according to an embodiment of the present invention comprises an explosion-proof frame unit. A case unit of the explosion-proof frame unit accommodates an IGBT. A conductive bus bar is coupled to the case unit so as to surround same. Therefore, the hardness of the case unit is reinforced and, even if the accommodated IGBT explodes, debris is not discharged to the outside. The case unit has a plurality of inner communication grooves and outer communication grooves. The inner communication grooves and the outer communication grooves are arranged to cross each other. A buffer space part is formed between the inner communication grooves and the outer communication grooves. Therefore, even if the IGBT explodes, debris is not arbitrarily discharged.
