Abstract
The invention relates to a supporting and connecting piece for a micro-diameter thin wall pipe and a partition board of a heat exchanger. The supporting and connecting piece is processed through a block piece. The supporting and connecting piece is processed through the following steps: first, two kinds of irregular square grooves, namely long square grooves and short square grooves, are processed along a length direction, the two kinds of the square grooves mutually and alternately appear, then circular holes are processed in the center perpendicular to the surfaces of the grooves, one circular hole is processed in each short square groove, two circular holes are processed in each long square groove, to be specific, the fifteen circular holes are processed in the ten grooves, namely the five long square grooves and the five short square grooves, the spaces between every two holes are the same, and finally, rounding is performed on the two sides of the supporting piece. The purpose of processing the square grooves and the circular holes is to enable the partition board to be inserted in and fixed on the supporting and connecting piece, and the purpose of the rounding is to enable the supporting and connecting piece to be uniformly mounted between an inner annular pipe and an outer annular pipe of the heat exchanger. The supporting and connecting piece disclosed by the invention provides support and connection for the micro-diameter thin wall pipe and the partition board. Through the adoption of the supporting and connecting piece, the possibility that the micro-diameter thin wall pipe is influenced by air currents to generate disturbance under actual working conditions is avoided, and the structure stability and the high-efficiency heat exchange coefficient of the heat exchanger under the actual working conditions are ensured.
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 can reach the cooling performance of coupling.Therefore, one of efficient heat transmission equipment main goal in research becoming researchers.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 difficult to reach requirement, must work out the heat exchanger that a kind of structure is compacter, the coefficient of heat transfer is higher for this reason.The structure of this new type heat exchanger mainly contains inner and outer rings pipe, arm, micro-footpath light-wall pipe, and inlet/outlet pipe composition.Because micro-footpath light-wall pipe can be subject to very strong flow perturbation under actual condition, make it that side direction or transverse shifting occur, thus need to add dividing plate between the light-wall pipe of micro-footpath, the gap between the light-wall pipe of micro-footpath is remained unchanged.But these dividing plates do not have supporting-point, can not bearing load, so need 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, welded 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 each parts relative positional accuracy, or some function such as complete independently shelf, bracket, workbench.Supporting connecting piece basic demand: should have enough Static stiffness, higher rigidity-weight ratio, have good dynamic characteristic, its solid-state properties is declined and overlapped with excited frequency and resonate, and should have good Characteristics of Thermal deformation etc.
Because Novel heat exchanger structure is compact, micro-footpath light-wall pipe and dividing plate only have several millimeters apart between ring-shaped round pipe, 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 the situation that disturbance occurs heat exchanger micro-footpath light-wall pipe under actual condition, a kind of supporting connecting piece being applicable to 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.
