Description
Technical field
This utility model relates to aero engine technology field, particularly relates to a kind of wall body to be cooled
Structure, the turbo blade that this walled structure to be cooled is set and aero-engine.
Background technology
Turbine is one of important component part of aero-engine.
In order to obtain more preferable propulsive efficiency, before aero-turbine, temperature improves constantly, this
Turbo blade is made to be faced with the most severe working environment, therefore high in the urgent need to Development of Novel
The blade cooling structure of effect.Traditional turbo blade many employings internal impact, rib or turbulence columns are strong
Change internal cooling and the compound cooling structure form of outside gaseous film control.In recent years, gradually propose
Walled structure to be cooled is designed as the double-wall structure of impact aerating film, whole due to this structure
Body cooling effect is far above tradition methods for cooling, thus double-wall structure is gradually applied to reality
Blade.
Applicants have discovered that: prior art at least exists techniques below problem:
As it is shown in figure 1, common double-wall structure is to arrange at inwall (also referred to as inner layer wall) 71
Impact opening 73, outer wall (also referred to as outer wall) 72 arranges air film hole 74.Air-flow is from impact opening 73
Impact upper wall surface i.e. outer wall 72, i.e. from gas after the shortest distance that then flows between two layers of walls
Fenestra 74 flows out, and this makes cold air main impingement heat transfer effect that obtains in two layers of walls, and convection current
Heat transfer effect is more weak.Even if strengthening disturbance at two layers of walls intermediate arrangement rib or turbulence columns structure,
Owing to cold air flow distance is shorter, disturbance effect also income is little.Further, since outer wall 72
Thick relatively thin so that the generally air film hole 74 of double-wall structure all uses basis borehole structure.Circular hole
Jet is concentrated, and the air film exhibition of formation is the best to distribution, and the normal direction speed of air film hole 74 outlet jet
Degree is relatively big, and the air film of formation is difficult to preferably attach wall.
Additionally, the effect of the cooling for improving air film, prior art additionally provides a kind of at turbine
The technical scheme of the groove with exhibition stream function connected with air film hole is set on blade outer wall, logical
Cross the mode that groove improves the horizontal coverage effect of the air-flow that air film hole flows out, improve air film distribution
Homogeneity, but due to the usual thinner thickness of turbo blade outer wall, so the degree of depth of groove is shallower,
Fail to be effectively improved the coverage effect that air-flow is horizontal, and arranging of groove can be greatly reduced whirlpool
The intensity of impeller blade outer wall, causes turbo blade outer wall to reduce service life.
