摘要： A cooling system capable of adequately press-quenching an extruded product of heat-treatable aluminum alloy immediately after extrusion without causing deformation and warpage in its cross section. The cooling system consists of a compressor 22 and a plurality of compressed air amplifiers 21 which are arranged in lines around and along the passage of the extruded product. The compressed air amplifiers 21a placed farthest from the exit are modified such that the compressed . air conduit 26 is provided with a hose 36 for water supply. The compressed air amplifiers 21 and 21a receive compressed air at a certain flow rate from the compressor 22, and then they direct cooling air to the surface of the extruded product at an amplified flow rate. The thus generated cooling air cools the extruded product several times faster than fan cooling. In addition, cooling air ejected from the compressed air amplifiers arranged farthest from the exist of the extruder contains mist which rapidly cools the extruded product.
