Description
Technical field
The present invention relates to a kind of supporting connecting piece for heat exchanger micro-footpath light-wall pipe and dividing plate, it is applicable to play location to micro-footpath light-wall pipe and dividing plate and provide carrying effect, belongs to aviation Astronautics technical field.
Background technology
Along with the continuous lifting of aero-engine dynamic property, its cooling system also must be able to reach the cooling performance of coupling. Therefore, one of efficient heat transmission equipment main goal in research becoming researcheres. Novel aero-engine has the feature such as High Mach number, high heat exchange efficiency, and the requirement of this heat exchanger is higher, and traditional heat exchanger is extremely difficult to requirement, must work out, for this, the heat exchanger that a kind of structure is compacter, the coefficient of heat transfer is higher. The structure of this new type heat exchanger mainly has inner and outer rings pipe, arm, micro-footpath light-wall pipe, and inlet/outlet pipe composition. Owing to micro-footpath light-wall pipe can be subject to very strong flow perturbation under actual condition so that it is laterally or transverse movement occurs, thus needing to add dividing plate between the light-wall pipe of micro-footpath, the gap between the light-wall pipe of micro-footpath is made to remain unchanged. But these dividing plates do not have supporting-point, it is impossible to bearing load, so needing to increase supporting connecting piece in dividing plate both sides.
Traditional supporting member is of a great variety. Support class, case shell class, frame class, flat-type can be divided into by make; Monoblock type and assembled can be divided into by structure; Cast type, welding type, bolt type etc. can be divided into by manufacture method. Member structure, plate and shell structure and entity structure can be divided into by mechanical model. The main function of supporting member has supporting and installs each parts, and bear various static force (gravity) and dynamic force (cutting force, vibration force), ensure some function such as each parts relative positional accuracy, or complete independently shelf, bracket, workbench. Supporting connecting piece basic demand: should having enough Static stiffness, higher rigidity-weight ratio, have good dynamic characteristic, its solid-state properties is not put and overlapped with excited frequency and resonate, and should have good Characteristics of Thermal deformation etc.
Owing to Novel heat exchanger structure is compact, micro-footpath light-wall pipe and dividing plate are between ring-shaped round pipe only several millimeters, and need supporting connecting piece can be supplied to the effect of membrane support and connection, and traditional supporting member is difficult to apply in this new type heat exchanger. For the support member of new exclusive must be studied. The present invention is directed to heat exchanger micro-footpath light-wall pipe and the situation of disturbance occurs under actual condition, a kind of supporting connecting piece suitable in new type heat exchanger micro-footpath light-wall pipe and dividing plate is proposed, this supporting member can be arranged in heat exchanger well, and provides carrying to micro-footpath light-wall pipe and dividing plate.

Pitch of holes is identical. Last at support member both sides rounding. The purpose of processing square groove and circular hole is to make dividing plate be inserted into and be fixed on support connector. Rounding is in order to supporting connecting piece can be arranged between heat exchanger inside-and-outside ring pipe.
Fig. 3 is supporting connecting piece and heat exchanger assembling schematic diagram. It includes micro-footpath light-wall pipe, supporting connecting piece, internal ring pipe, outer shroud pipe and arm. A pair arm is separately mounted on internal ring pipe and outer shroud pipe. Micro-footpath light-wall pipe in the shape of a spiral, is drawn from internal ring arm, sequentially passes through the dividing plate being inserted in supporting connecting piece groove, arrives outer shroud arm. Making spacing between the light-wall pipe of micro-footpath remain unchanged by dividing plate, dividing plate inserts in supporting connecting piece square groove, is fixed by screw. Supporting connecting piece is connected between internal ring pipe and outer shroud pipe, has 10 groups of supporting connecting pieces, and is evenly distributed between internal ring pipe and outer shroud pipe.
Wherein, in Fig. 1 and 2, supporting connecting piece overall dimensions is 2mm �� 2mm �� 48mm, and short, rectangular slot parallel-segment length respectively 2.7mm and 5.4mm, groove width is 1mm. Circularhole diameter is 1mm, and in first groove, the circular hole heart is 5.707mm from part left surface, and between circular hole, spacing is 2.7mm, and each round hole axial and X-axis positive direction angle are shown in chart. Through-thickness chamfering is R7mm.
Wherein, in Fig. 3, first supporting connecting piece is 15 �� with X-axis positive direction angle, and between supporting connecting piece, angle is 36 ��, and supporting connecting piece and center of circle closest approach distance are 155mm.
(3) advantage and effect
The present invention is based in heat exchanger micro-footpath light-wall pipe and by air-flow, disturbance is occurred under actual condition, bring it about laterally or transverse movement, cause that micro-footpath light-wall pipe trembles, mutual spacing is made to change, have a strong impact on the coefficient of heat transfer and the service life of heat exchanger, the novel supporting connecting piece of design specialized, advantage is mainly reflected in: supporting connecting piece reasonable layout is in heat exchanger between internal ring pipe and outer shroud pipe, and the impact of heat exchanger total quality is not as big; Dividing plate is inserted in supporting connecting piece square groove, dividing plate is made to be linked together by supporting connecting piece and inner and outer ring pipe, there is provided carrying can to micro-footpath light-wall pipe and dividing plate, efficiently solve micro-footpath light-wall pipe and the dividing plate perturbed problem under actual condition, make the structure of heat exchanger more stable and firmly, it is ensured that heat exchanger the stablizing of the coefficient of heat transfer under actual condition.
