旋涡式制冷器可用来冷却熔焊或堆焊零件,可对切削刀具降温以提高其耐久性,可对数控机床的电子部件进行冷却以提高其工作稳定性。旋涡式制冷器以压缩空气系统的压缩空气作为能源。旋涡式制冷器为一管形件(见图)。管子的环形腔中设有一旋涡件,其通道具有矩形截面,截面宽b,高h。管子壳体通道的外端焊着压缩空气引入接头。在壳体的环形腔中,用螺母2固定着直径 Vortex coolers can be used to cool the weld or build-up parts, cool the cutting tool to improve durability, and cool the electronics of the CNC machine to improve its operational stability. Vortex coolers use compressed air from a compressed air system as their energy source. The vortex cooler is a tube (see photo). A vortex element is arranged in the annular cavity of the pipe, the channel of the pipe has a rectangular section, a section b and a height h. The outer end of the channel of the shell of the tube is welded with compressed air and introduced into the joint. In the annular chamber of the housing, the diameter is fixed with a nut 2
