摘要：The paper deals with the problem with flowing of cooling air using a phenomenon called the Coanda effect. With the help of the designed device, it is possible to generate an oriented air flow for cooling, using the Coanda effect. By means of the formed oriented air stream, it is possible to cool the pipes after heating, i.e. after welding, bending or heat treatment. The experimental part consists of designs and comparisons of design solutions of the device in the program ANSYS Fluent where the analysis of the problem of impact cooling and various device designs and measurement of actual values.
