FIELD: mechanical engineering. ^ SUBSTANCE: thermo force post is designed for protection of parts and units from high density heat circuits including protection of sensors of working medium parametres, communicating lines, and also devices for spraying additional medium arranged in circuit of high rate high temperature actuating medium of power unit. The post has aerofoil and is mounted of the wall of the circuit on one side or on walls of the circuit on two opposite sides and consists of communicating cavities and channels including a channel of cooling agent supply located in its front part. A front part of the post is equipped with a rounded front edge with a lengthwise slit communicating with the cooling agent supply channel. Additionally the post contains a porous insertion installed in the slit of the front edge and attached to the latter by diffusion welding. The insertion is made with ratio of width to thickness within range from 2.0 to 4.0. ^ EFFECT: facilitating reduced consumption of cooling agent, operability of system, parts, units, communicating lines, and hydraulic and fuel mains arranged in post due to uniform distribution of cooling agent along whole area of cooled surface. ^ 5 cl, 5 dwg |
