Abstract
The invention relates to a novel flexible radiating tube and main sheet connecting structure of an intercooler. The novel flexible radiating tube and main sheet connecting structure is characterized in that radiating tubes are fixedly connected into holes of a main sheet, first reinforcing sleeves are arranged on the inner walls of the holes of the main sheet, and the radiating tubes extend into the outer walls in the holes of the main sheet to be connected with the first reinforcing sleeves; a reinforcing plate is welded on the outer side of the main sheet, and second reinforcing sleeves are arranged among the reinforcing plate and the outer walls of the radiating tubes. The novel flexible radiating tube and main sheet connecting structure has the advantages that the novel flexible radiating tube and main sheet connecting structure is simple, and is low in manufacturing cost and working temperature and convenient to assemble, damage to the radiating tubes due to stress can be effectively reduced, the influence due to vibration of a unit can be reduced, the strength of stress concentration regions of the radiating tubes is improved, the radiating tubes are further protected, the service lives of the radiating tubes are prolonged, the strength of connection among the radiating tubes and the main sheet is obviously improved, the problem of destructive influence due to stress and vibration of equipment at a high temperature can be effectively solved, and the service life of the intercooler can be prolonged.
Description
Technical field
The present invention relates to the syndeton of a kind of radiating tube and main leaf, relate in particular to a kind of novel flexible intercooler radiating tube and main leaf syndeton.
Background technology
The operating temperature of charge air cooler is higher, and usually all more than 140 ℃, at some, on large-scale generating set, the operating temperature of charge air cooler even can reach 250 ℃.Due to the impact of high temperature, the Light Difference between radiating tube and main leaf expand can cause producing stress between radiating tube and main leaf, and stress concentrates on radiating tube near main leaf welding point place.Under the long duration of action of stress, the vibrations while adding unit work, radiating tube is easy to produce slight crack near the place of main leaf welding point, until leak.Not obvious on this situation charge air cooler lower in operating temperature, but in operating temperature, on high charge air cooler, just highlighted.
Summary of the invention
The present invention for overcome the above problems provide a kind of simple in structure, bonding strength is high, novel flexible intercooler radiating tube and the main leaf syndeton in ease of assembly, prolongation charge air cooler service life.
Technical scheme of the present invention is: described radiating tube is fixedly connected in the main leaf hole, and described main leaf hole inwall is provided with reinforcing sleeve one, and the outer wall that described radiating tube stretches in the main leaf hole is connected with reinforcing sleeve one; Described main leaf outside welding one deck stiffener, be provided with reinforcing sleeve two between this stiffener and radiating tube outer wall.
Described stiffener, radiating tube and reinforcing sleeve two are welded as a whole.
Described stiffener is for being interrupted wavy rib, and the stiffener two ends are that flat and the main leaf outside are welded and fixed, and the faying face of described stiffener and reinforcing sleeve two is contacts side surfaces, and stiffener contacts with reinforcing sleeve one bottom.
Described radiating tube caliber is slightly less than the main leaf aperture.
The present invention is simple in structure, production cost is low, operating temperature is low, easy to assembly; effectively reduce the destruction that stress causes radiating tube; reduce the impact that the unit vibrations bring; increase the intensity of radiating tube region of stress concentration, further protected radiating tube, extended the service life of radiating tube; significantly improve the bonding strength between radiating tube and main leaf; the present invention can effectively solve the damaging influence that under high temperature, the vibrations of stress and equipment bring,, the service life of having improved charge air cooler.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of prior art.
In figure, 1 is main leaf, the 2nd, and radiating tube, the 3rd, stiffener, the 4th, reinforcing sleeve one, 5th, reinforcing sleeve two.
The specific embodiment
Novel flexible intercooler radiating tube and main leaf syndeton, described radiating tube 2 is fixedly connected in main leaf 1 hole, consider the convenience of assembling, the size in main leaf 1 hole is larger than the size of radiating tube 2, simultaneously for radiating tube 2 and main leaf 1 can be linked together, guarantee the bonding strength of main leaf 1 and radiating tube 2, at described main leaf 1 hole inwall, reinforcing sleeve 1 is set, the outer wall that described radiating tube 2 stretches in main leaf 1 hole is connected with reinforcing sleeve 1, so both facilitate the assembling of core body, also guaranteed the bonding strength between radiating tube 2 and main leaf 1, stiffener 3 at the outside of main leaf 1 welding layer of material thinner thickness, described stiffener 3 is for being interrupted wavy rib, stiffener 3 two ends are that flat and main leaf 1 outside are welded and fixed, be provided with reinforcing sleeve 25 between this stiffener 3 and radiating tube 2 outer walls, described stiffener 3 is contacts side surfaces with the faying face of reinforcing sleeve 25, stiffener 3 contacts with reinforcing sleeve one 4 bottoms, described stiffener 3, radiating tube 2 is welded as a whole with reinforcing sleeve 25, this stiffener 3 can absorb dilatancy by the rib of compacting on it, avoid producing stress, the vibrations that unit produces have also been absorbed simultaneously.
