Embodiment Construction

[0025] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0026] see Figure 1 to Figure 4 shown.

[0027] A self-circulating cooling honeycomb base structure of the present invention comprises:

[0028] The seat body 1 of the honeycomb seat;

[0029] Casting forms a plurality of ribs 2 distributed at intervals on the bottom surface of the top groove of the seat body 1;

[0030] The front wall surface and the rear wall surface of the seat body 1 are respectively provided with front-end inlet grooves 11 and rear-end outlet grooves 12 for gas flow. Disturbance, thereby enhancing heat exchange and improving heat exchange efficiency, the top grooves of the seat body 1 between adjacent honeycomb seats pass through the front inlet groove 11 and the rear outlet groove 12 for gas exchange flow.

[0031] When adjacent honeycomb seats are installed, the rear end outlet groove 12 of the previous...

Abstract

The invention discloses a self-circulation cooling honeycomb base structure. The self-circulation cooling honeycomb base structure comprises a base body of a honeycomb base, and ribs distributed on the bottom surface of a top groove of the base body at intervals, a front end inlet groove and a rear end outlet groove for air to flow are correspondingly formed in the front wall face and the rear wall face of the base body, after air enters the top groove of the base body, turbulent flow is formed on the ribs distributed at intervals, and the top groove of the base body between adjacent honeycomb bases conducts air exchange flow through the front end inlet groove and the rear end outlet groove. Therefore, heat exchange is enhanced, the heat exchange efficiency is improved, The top groove of the base body between the honeycomb bases carry out gas exchange flow through the front end inlet groove and the rear end outlet groove, and gas can carry out efficient heat exchange among the honeycomb bases, so that the cooling effect of the honeycomb bases is improved, the temperature bearing capacity of the honeycomb bases is improved, and the problem that gas cannot perform efficient heat exchange among a plurality of honeycomb bases is solved.

Description

technical field [0001] The invention relates to a self-circulating cooling honeycomb base structure, which belongs to the technical field of aircraft engine honeycomb bases. Background technique [0002] Due to the pursuit of the thrust-to-weight ratio of modern engines, it is necessary to continuously increase the temperature of the hot-end parts of the engine to improve the thermal efficiency of the engine. The components are efficiently cooled. The honeycomb seat installed in the engine is one of the hot end stator parts. When the engine is running, the honeycomb seat will be subjected to heat conduction from the gas and frictional heat from the engine rotor blades, so it needs to be heated when the engine is running. Honeycomb base for cooling; [0003] In the Chinese patent publication number CN112523813A of the aero-engine turbine rim sealing structure, the airflow carries out integral heat dissipation and cooling on a plurality of honeycomb seats installed on the cas...
