Abstract
The utility model discloses a tube plate welding structure of an air cooler. The tube plate welding structure comprises an installation plate, wherein a plurality of through holes are formed on the installation plate; finned tubes are inserted into the through holes; the diameters of the through holes are matched with the outer diameters of the finned tubes; the installation plate at the peripheries of the through holes is further provided with grooves concentric with the through holes; and the width of an annular boss between each groove and each through hole is smaller than or equal to the thickness of the tube wall of each finned tube. Due to the adoption of the tube plate welding structure, the phenomenon of deformation of the plate surface of the installation plate during welding is avoided. Welding connection is performed by melting the annular boss during welding, so that the use of a welding flux is avoided or the using amount of the welding flux is saved, and the welding processing cost is lowered.
Description
Technical field
The utility model relates to air cooler, refer in particular to air cooler the tube sheet Welding Structure.
Background technology
The tube plate structure of air cooler is in the market offered several intensive through holes on its installing plate, finned tube is located on the through hole one by one.Owing to finned tube need be fixed on the installing plate, and not allow the slit existence between the through hole of finned tube and installing plate, must be sealing state, all be to realize usually therefore by finned tube is welded on the installing plate.For finned tube is welded on the installing plate, adopt usually and weld between the through hole and finned tube of a side at installing plate, outwards set out one one-tenth trumpet-shaped space along through hole for the scolder filling, by scolder finned tube is welded on the installing plate.Because finned tube pipe number is numerous, in welding process, the very high need welding position of installing plate need the thawing of welding temperature is in the same place with solder bonds, and when welding, the high-temperature of welding can cause along with other positions that installing plate is directly delivered to installing plate and expands with heat and contract with cold.Because finned tube pipe number is numerous, all need to be welded on the installing plate, therefore, after welding job was finished, because the principle of expanding with heat and contract with cold, each welding position of installing plate was heated inhomogeneous, causes whole erection plate center fullness.When tube plate structure is installed to the air compartment of air cooler,, is difficult to accomplish to the sealing of tube plate structure and causes the poor sealing phenomenon because installing plate is uneven.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of can the assurance in the welding quality when welding, can guarantee that again installing plate keeps smooth tube sheet Welding Structure.
In order to solve the problems of the technologies described above, the technical scheme that the utility model provides is a kind of tube sheet Welding Structure of air cooler, it comprises installing plate, offers several through holes on described installing plate, in described through hole, be equipped with finned tube, described through-hole diameter and described finned tube external diameter are complementary, it is characterized in that also offering on the described installing plate of described through hole periphery a groove concentric with described through hole, the width of the annular boss between described groove and the described through hole is less than or equal to the pipe thickness of described finned tube.
The utility model, only needs that annular boss is applied welding temperature its fusing is fixed together with finned tube when welding by offer annular boss around through hole on installing plate.Because the existence of annular groove has stoped the direct conduction of most of heat energy, the bad phenomenon of installing plate plate face generation deformation when having avoided welding.Owing to when welding, be to be welded to connect by the fusing annular boss, the use amount of having avoided the use of scolder or having saved scolder has reduced the welding processing cost again.

The specific embodiment
Now lift a preferred embodiment and the utility model structure is specifically described in conjunction with graphic.Referring to Fig. 1, Fig. 2, Fig. 3, wherein:
The tube sheet Welding Structure, it comprises two installing plates 10, installing plate 10 is a metal material.Offering the through hole 11 of several marshallings on every installing plate 10, is the center of circle with the center of each through hole 11, with greater than the radius of this through hole radius round through hole 11, on installing plate 10, offer an annular groove 12.Form an annular boss 13 between annular groove 12 and through hole 11, the width of this annular boss 13 is equal to or less than the pipe thickness of finned tube 20.When welding, finned tube 20 is worn in the through hole of installing plate 10 into, the annular boss 13 that will be centered around the finned tube outer wall that is located in the through hole by welding equipment melts and it is combined under the high temperature melting state with finned tube 20 be welded as a whole.Firmer in order to weld, can when welding, use a spot of scolder.Owing to around each through hole of installing plate 10, all offer annular groove 12, therefore when welding, the high heat energy that touches annular boss 13 can not be by the shortest distance to other local conduction of installing plate, have avoided moment heat energy to conduct to the rough bad deformation phenomenon on the installing plate surface that other positions of installing plate cause because of expanding with heat and contract with cold.
