This utility model relates to a heat exchange structure for an industrial robot chassis, comprising a long, narrow space within the chassis, air inlets staggered along the height direction with outer and inner side plates respectively, and a heat exchange mechanism sealed within the long, narrow space and spaced apart from the two air inlets. Each air inlet is connected to a fan for supplying air into the long, narrow space. Air outlets are provided on both the outer and inner side plates, staggered along the height direction. In use, the heat exchange plates separate the outside environment from the chassis cavity. Air inside the chassis cavity is blown onto the heat exchange plates by a fan, exchanges heat with the plates, and then returns to the chassis through the outlets on the inner side plates. Outside air is sent into the long, narrow space by another fan, absorbs heat from the heat exchange plates, and is then discharged from the outlets on the outer side plates. This achieves heat exchange while preventing outside air from entering the chassis, meeting practical requirements.
