Abstract
The utility model discloses a novel thermal-edge corrugation device, which consists of a secondary corrugated plate I, a secondary corrugated plate II and a primary corrugated plate. The whole corrugated plate is made into an arc-shaped corrugated form. One end of the primary corrugated plate is provided with the secondary corrugated plate I, and the other end of the primary corrugated plate is provided with the secondary corrugated plate II. The secondary corrugated plate I is corrugated, the port part is made into a tapered edge, and the edge of the plate is made into an oblique-angle form. The secondary corrugated plate II is corrugated, the port part is made into a tapered edge, one end of the plate body is cut into an arc-shaped opening, and the edge of the arc-shaped opening is in a beveling form. The wave crest of the whole corrugated plate is plane. The novel thermal-edge corrugation device has a simple structure and good cooling effect.
Description
Technical field:
The utility model relates to a kind of undulator, and the hot limit of particularly a kind of aircraft undulator has the good cooling results characteristics.
Background technique:
At the exhaust duct cooling system of aircraft, be widely applied to hot limit undulator.Existing hot limit undulator mainly is made of corrugated sheet, and its shortcoming is a corrugated sheet after it is shaped, ripple struction instability, 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 hot 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 integral body is made the circular arc 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 panel edges is made the rake angle shape;
Described complementary wave card II is a corrugated, and port section is made the tapering featheredge, and plate body one end-grain cutting has the circular arc mouth, and circular arc mouth edge is the shape of cutting sth. askew.
The crest of described corrugated sheet is flat 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 drawing 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 hot 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, described complementary wave card I 1 is a corrugated, and overlap is made the tapering featheredge, the edge angled shape of cutting sth. askew, described complementary wave card II 2 is a corrugated, and overlap is made the tapering featheredge, and plate body has been cut the circular arc mouth and the edge is the shape of cutting sth. askew, unitary moulding is a circular arc, has characteristics such as cooling effect is obvious.
