Abstract
A kind of annular radiator, the annular radiator is mounted on aircraft engine duct outer wall, including outside shaping frame (1), duct abutting joint frame (4) and it is alternately arranged the air duct (2) and oil pathway (3) between shaping frame (1) and duct abutting joint frame (4) on the outside.The annular radiator of the utility model occupies little space, and does not influence the distribution in flow field in engine duct, and hot side lubricating oil enters radiator from oil inlet, flows through oil pathway, is flowed out from oil outlet；The cold air stream of aircraft engine duct is exchanged heat through air duct, two kinds of fluids by dividing wall type heat exchange, so as to achieve the purpose that radiate to lubricating oil medium, meets the requirement of aero-engine.
Description
Technical field
The utility model is related to heat spreader structures more particularly to a kind of annulars on aircraft engine duct outer wall
Radiator.
Background technology
Aircraft engine oil radiator relies primarily on fuel oil and lubricating oil radiator and regular air oil cooler to lubricating oil
It radiates.However, with the raising that the increase and fuel-economizing (cruise duration) of aeroengine power require, fuel oil is used as to boat
The heat sink apparent deficiency of empty motor oil heat dissipation, fuel oil radiator have been unable to meet requirement, and regular air lubricating oil
Radiator occupied space is big, and power limited, it is impossible to meet the requirement of aero-engine.
Utility model content
The purpose of this utility model is to provide a kind of annular radiator on aircraft engine duct outer wall, with reality
Existing air lubricating oil heat exchange, while space is saved, and do not influence the power of aero-engine in itself.
The above-mentioned purpose of the utility model is achieved through the following technical solutions：
A kind of annular radiator, the annular radiator are mounted on aircraft engine duct outer wall, are molded including outside
Frame and duct abutting joint frame and the air duct being alternately arranged between shaping frame on the outside and duct abutting joint frame and cunning
Oily channel.
Further, the air duct is identical with the number of oil pathway or the number of air duct is led to than lubricating oil
The number in road is big by 1.
Further, the air duct and oil pathway are all with radiating fin, increasing heat radiation area, and increase channel
Bearing capacity.
Further, the shape of the radiating fin is rectangular saw-tooth wave, triangular wave or sine wave shape, to increase heat dissipation
Area.
Further, the material of the annular radiator is aluminium alloy, can reduce the weight of radiator.
Further, the annular radiator is spliced by multistage, in order to process.
The annular radiator of the utility model is mounted on aircraft engine duct, is occupied little space, is not influenced engine
The distribution in flow field in duct.Hot side lubricating oil enters radiator from oil inlet, flows through oil pathway, is flowed out from oil outlet；Fly
Through air duct, built-in fin increases heat dissipation area and increases the coefficient of heat transfer simultaneously the cold air stream of machine engine duct, and two
Kind fluid is exchanged heat by dividing wall type heat exchange, so as to achieve the purpose that radiate to lubricating oil medium, meets aero-engine
It is required that.
Description of the drawings
Fig. 1 is the integrally-built schematic diagram for the annular radiator for representing the utility model；
Fig. 2 is the enlarged diagram at the A in Fig. 1；
Fig. 3 is the schematic diagram of the air duct or oil pathway in the annular radiator for represent the utility model.
Specific embodiment
Below with reference to the accompanying drawings, the technical solution of the utility model is described in detail in conjunction with the embodiments.
Fig. 1 schematically illustrates the overall structure of the annular radiator of the utility model, and Fig. 2 is that the amplification at the A in Fig. 1 is shown
It is intended to.As shown in the figure, in the present embodiment, the annular radiator of the utility model is the cyclic annular aluminum plate of large size of diameter 640mm
Fin type heat exchanger including outside shaping frame 1, duct abutting joint frame 4 and is alternately arranged shaping frame 1 and duct on the outside
3 air ducts 2 and 2 oil pathways 3 between abutting joint frame 4.Wherein, air duct 2 and oil pathway 3 are by 8 He of fin
Partition board 7 forms, with increasing heat radiation area, as shown in Figure 3.Air duct 2 and oil pathway 3 are alternately to be superimposed, then as one
A integral installation is on the outside between shaping frame 1 and duct abutting joint frame 4.
In embodiment, the material of the annular radiator of the utility model be aluminium alloy, such as 6061 aluminium alloys or other
The aluminium alloy of series can reduce the weight of radiator, but titanium alloy or stainless steel material also can be selected.Fin shape can be square
The shapes such as shape sawtooth wave, triangular wave, sine wave, with increasing heat radiation area, preferably rectangular saw-tooth wave.
In embodiment, the annular radiator of the utility model is spliced by 3 sections, in order to process, it is of course also possible to
It is spliced by 2 sections or more sections, if possible, can be also processed and formed at one time.
Although the situation of 3 air ducts and 2 oil pathways is illustrated in this example, but the utility model is not limited to
This, can be increased and decreased as the case may be, and the number of the air duct 2 and oil pathway 3 can be identical, but usual air
The number of channel is bigger than the number of oil pathway by 1.
When product works, hot side lubricating oil enters radiator from lubricating oil ozzle import 5, oil pathway 3 is flowed through, from oil pipe
6 outflow of mouth outlet；The cold air stream of aircraft engine duct increases heat dissipation area and increases simultaneously through air duct 2, built-in fin 8
The coefficient of heat transfer is added, two kinds of fluids are exchanged heat by dividing wall type heat exchange, so as to achieve the purpose that radiate to lubricating oil medium.
Although described above is the principle and specific embodiment of the utility model, in the upper of the utility model
It states under guidance, those skilled in the art can carry out various improvement and deformation on the basis of above-described embodiment, and these are improved
Or deformation fall it is within the protection scope of the present utility model.It will be understood by those skilled in the art that above-mentioned specific description is
In order to explain the purpose of this utility model, it is not intended to limit the utility model.The scope of protection of the utility model will by right
It asks and its equivalent limits.
