DEVICE FOR TREATING METAL WORKPIECES WITH COOLING GAS

In order to achieve an increase in energy efficiency and quicker quenching of workpieces in a device for treating metal workpieces with cooling gas, consisting of a horizontally arranged cylindrical housing (1) having at least one closable opening for inserting and removing the workpieces to be treated, having a quenching chamber (2) for receiving the workpieces to be treated located inside the housing (1), having two high-performance fans (5 and 6 ) arranged laterally and outside the quenching chamber (2) for guiding a cooling gas through the quenching chamber (2), and having two heat exchangers (11 and 12) for cooling the cooling gas, according to the present invention, it is proposed that each heat exchanger (11 or 12) is allocated to a high-performance fan (5 or 6) and that closable guiding devices (17 and 18) are arranged above and below the quenching chamber (2). 用于用冷却气体处理金属工件的设备包括：平放设置的圆柱形壳体(1)，所述壳体具有至少个用于将要处理的工件引入和引出的可封闭的开口；位于壳体(1)内部的淬火腔室(2)，所述淬火腔室用于容纳要处理的工件；两个侧向地设置在淬火腔室(2)外部的高功率鼓风机(5和6)，所述高功率鼓风机用于引导冷
