Abstract
A novel edge cooling corrugated unit is composed of an auxiliary corrugated plate I, an auxiliary corrugated plate II and a main corrugated plate. The main corrugated plate in an arc shape is corrugated, the auxiliary corrugated plate I is arranged at one end of the main corrugated plate, and the auxiliary corrugated plate II is arranged at the other end of the main corrugated plate. Besides, the auxiliary corrugated plate I is in corrugated shape, a taper feather edge is formed at the end opening of the auxiliary corrugated plate I, and a flange is arranged at the edge of the auxiliary corrugated plate I; the auxiliary corrugated plate II is also in corrugated shape, a taper feather edge is formed at the end opening of the auxiliary corrugated plate II, and a body of the auxiliary corrugated plate II is in an arc shape; and the crest of the main corrugated plate is circular. Therefore, the novel edge cooling corrugated unit is simple in structure and fine in cooling effect.
Description
Technical field:
The utility model relates to a kind of undulator, and the cold limit of particularly a kind of aircraft undulator has the good cooling results characteristics.
Background technique:
Exhaust duct cooling system at aircraft is applied to cold limit undulator widely.Existing cold limit undulator is made by corrugated sheet, and its shortcoming is after it is shaped, and that ripple shrinks is unstable, easy deformation and do not reach the effect of heat radiation.
The model utility content:
At the technical deficiency of existing the said goods, the purpose of this utility model provides a kind of novel cold limit undulator, and it is made up of complementary wave card I, complementary wave card II, main corrugated sheet.
The technological scheme that its technical problem that solves the utility model adopts is: corrugated sheet is made circular arc, becomes corrugated, and main corrugated sheet one end is provided with complementary wave card I, and the other end is provided with complementary wave card II.
Described complementary wave card I is a corrugated, and port section is made the tapering featheredge, and complementary wave card edge is provided with flange;
Described complementary wave card II is a corrugated, and port section is made the tapering featheredge, and plate body is made the circular arc mouth.
The crest of described corrugated sheet is the circle shape.
The utility model beneficial effect: simple in structure, good cooling results.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is a unitary moulding structural representation of the present utility model;
Among the figure 1, complementary wave card I 2, complementary wave card II 3, main corrugated sheet
Embodiment:
As shown in Figure 1, the utility model is a kind of novel cold limit undulator, it is by complementary wave card I 1, complementary wave card II 2, main corrugated sheet 3 is formed, main corrugated sheet 3 one ends are provided with complementary wave card I 1, one end is provided with complementary wave card II 2, described main corrugated sheet 3 is a circular arc, become corrugated, the port section of described complementary wave card I 1 is made the tapering featheredge, complementary wave card edge is provided with flange, and complementary wave card II 3 is for being corrugated, and port section is made the tapering featheredge, plate body is made the circular arc mouth, the crest of described corrugated sheet is circle shape, complementary wave card I 2, the limit mouth of complementary wave card II 3 overlaps mutually, and unitary moulding is a circular arc, the few waveform in two ends has characteristics such as cooling effect is obvious.
