Technical field
The present invention relates to the heat transfer technology field, relate in particular to a kind of aluminium cooler water inlet pipe and water outlet pipe syndeton
Background technology
At present, in fields such as railway traffic, engineering machinery and space flight, the used material of cooler mainly contains three kinds of materials such as copper alloy, aluminium alloy and stainless steel.With regard to three kinds of materials comparatively speaking, its heat conductivility of copper alloy is best, machinability is also relatively good, mechanical strength is moderate; The aluminium alloy heat conductivility takes second place, and machinability is relatively good, and its weight is the lightest, but mechanical strength is lower; Its heat conductivility of stainless steel is the poorest, machinability is the poorest, but mechanical strength is best.In addition, because the mineral resources of China's aluminium alloy are relatively abundant, raw-material cost is lower, therefore, in various fields, generally adopts the mother metal of aluminum alloy materials as cooler.
At present, the aluminium cooler construction is divided into plate-fin, board-like, fin-tube type.
Strip-fin oil cooler by aluminium alloy is formed mainly is made up of air fin, water fin, composite plate, strip of paper used for sealing, water inlet pipe and water outlet pipe and hydroecium etc.Difference according to heat eliminating medium is divided into oil cooling and water-cooled, and following water fin, two kinds of situation of oily fin are referred to as the water fin, and each component names is an example with the water-cooled medium all.Parts such as its air radiating fin, water-cooled fin, composite plate and strip of paper used for sealing adopt mechanical connection or welding technique to consist of a complete cooler through the cooling core body of vacuum brazing composition cooler between water inlet pipe and water outlet pipe, hydroecium and the cooling core body.
Panel cooler mainly is made up of frid, flat board and the water inlet pipe and water outlet pipe etc. of aluminium matter, and frid is formed the mainboard of panel cooler with dull and stereotyped through vacuum brazing, adopts the process of screw thread or welding to be connected between water inlet pipe and water outlet pipe and mainboard.When the restriction of the device space; Adopt thread seal property to be connected between the pipeline in cooler water inlet pipe and water outlet pipe and the device cooling system; The lower situation of mechanical performance in view of aluminium; Generally adopt the transition tube connector of carbon steel material or in the Inlet and outlet water aluminum pipe, steel-wire screw-socket is installed, and the accuracy of screw machining of the Inlet and outlet water aluminum pipe of this structure requires than higher, processing cost is high; In addition, this connected mode generally is not suitable for the requirement of repeated disassembled and assembled and thread seal, through repeatedly causing sealing to descend because of the interface insufficient strength behind the repair and maintenance.
Summary of the invention
The technical problem that the present invention solved provides a kind of aluminium cooler water inlet pipe and water outlet pipe syndeton that can adapt to repeated disassembled and assembled.
The technical scheme that the present invention adopts is an aluminium cooler water inlet pipe and water outlet pipe syndeton; Comprise water inlet pipe and water outlet pipe; The stiff end of water inlet pipe and water outlet pipe is connected with aluminium cooler mainboard; The other end of water inlet pipe and water outlet pipe is the syndeton suitable with pipeline, and said water inlet pipe and water outlet pipe is fixedly connected with the mode of mainboard through compression casting.
Said water inlet pipe and water outlet pipe integral body is cylindric, and the center has axial through hole, adopts carbon steel to process.
As optimal way, said syndeton is the screw thread on the water inlet pipe and water outlet pipe body.
Screw thread on the said water inlet pipe and water outlet pipe body is internal thread or external screw thread.
Said water inlet pipe and water outlet pipe stiff end is provided with reinforced engagement means.
Said reinforced engagement means is the technology groove that is provided with on the water inlet pipe and water outlet pipe outer surface.
Said technology groove comprises at least one annular groove that circumferentially is provided with along water inlet pipe and water outlet pipe.
Said technology groove comprises along axially extended at least one groove of water inlet pipe and water outlet pipe.
Said technology groove comprises that groove and annular groove interweave along the axially extended groove of water inlet pipe and water outlet pipe.
The cross section of said technology groove is rectangular, triangle or circular arc.
The invention has the beneficial effects as follows; Provide a kind of install simple, reliability is high, the aluminium cooler water inlet pipe and water outlet pipe of compact conformation and the syndeton of aluminium cooler; Water inlet pipe and water outlet pipe and aluminium cooler are as a whole through being cast into, and the reliability of both connections is stronger, and the space of the shared equipment of whole aluminium cooler obtains reducing; Adapt to the installation of the radiator under the limited situation between the locomotive sky; Guaranteeing to have reasonable sealing again when connecting thread has higher intensity, reduced requirement to processing technology, practice thrift processing cost.

The specific embodiment
The structure that adopts the pressure casting process method to be connected between aluminium cooler water inlet pipe and water outlet pipe 3 of the present invention and aluminium cooler; Wherein water inlet pipe and water outlet pipe 3 is the pipe that a cylindric and center has axial through hole; The other end is a stiff end; Be connected with aluminium cooler mainboard 5, the other end is connected usefulness with equipment.The groove 1 of water inlet pipe and water outlet pipe 3 will adopt the process of die casting to be connected with the aluminium cooler with annular groove 4 parts, thereby pipe and aluminium cooler are become one, and make the cooler compact overall structure.Water inlet pipe and water outlet pipe 3 can adopt carbon steel, copper, stainless steel etc. as the water pipe mother metal, considers that from the intensity aspect the preferred carbon steel of the present invention is as water inlet pipe and water outlet pipe 3 mother metals.With device cooling system in pipeline be connected or when dismantling, the water inlet pipe and water outlet pipe 3 that carbon steel is processed can bear the dismounting of more times and pipeline.
Die casting is connected between the stiff end of water inlet pipe and water outlet pipe 3 and the aluminium cooler, in order to improve its connectivity robustness, the stiff end setting of water inlet pipe and water outlet pipe 3, reinforced engagement means.Can be the rib or the salient point of body surface protrusion, the technology groove or the pit that also can cave inward for the body surface.Consider that from angle easy to process that selection process groove of the present invention, the cross section of technology groove can be selected for use is rectangular, triangle or circular arc.Technology groove comprises at least one annular groove 4 that circumferentially is provided with along water inlet pipe and water outlet pipe 3, at least one groove 1 that perhaps extends vertically, and perhaps both combinations, and groove 1 interweave with annular groove 4.Prolong axial groove 1 and play a part to increase water inlet pipe and water outlet pipe 3 and aluminium cooler mainboard 5 axial intensity and contact area, annular groove 4 plays the axial intensity that further reinforcement water inlet pipe and water outlet pipe 3 is connected with the aluminium cooler.The required precision of above-mentioned technology groove is not high, can simplify working process, and improves whole working (machining) efficiency.
On the water inlet pipe and water outlet pipe 3 effect of the other end relative with stiff end be with cooling system on pipeline be connected; The structure that is used to connect should have sealing function simultaneously; Common seal form has end face seal, radial seal; For better sealing effectiveness, preferred version is on the water inlet pipe and water outlet pipe 3 screw thread to be set, and adopts the sealing gas thread.Can be internal thread 2 or external screw thread, can select, such as requirement of the suitable property of cooling system pipeline, installing space etc. according to field condition.
