Abstract
The utility model relates to a radiator assembly of automobiles, which belongs to the technical field of automobile radiator production and comprises a collecting main pipe (2), a radiating pipe (1) and radiating fins (3). The radiating pipe (1) is welded to the collecting main pipe (2), a hole on the radiating pipe is communicated with a hole on the collecting main pipe, and the radiating pipe (1) is welded to the radiating fins (3). The radiator assembly is characterized in that the radiating pipe (1) on the external portion adopts a multi-opening radiating pipe (1a2), and a reinforcing rib (1a2a) is arranged in a pipe cavity of the multi-opening radiating pipe (1a2). The radiator assembly is reasonable in design, adopts the multi-opening radiating pipe with the reinforcing rib, capable of avoiding bending deflection caused by welding the radiating pipe to the radiating fins in disposable welding of the radiator and resolving the problem of sinking of pipes in welding of the radiating pipe and the collecting main pipe, thereby ensuring welding quality and producing no waste product or inferior-quality product.
Description
Technical field
The utility model relates to automobile technical field, relates in particular to the automobile radiators production technical field.
Background technology
Because the needs of spatial placement; Require the automobile of high compactedness and reliability; The full aluminium welded structure radiator of normal employing is compared with the radiator of plastic-aluminum structure, and it adopts the aluminum header to replace the plastics hydroecium; Process with withholding technology with the plastics hydroecium again after the welding of disposable welding replacement core body, technology difficulty is bigger.Full aluminium welded structure radiator has adopted the widely used seriation O of prior art form height welded tube frequently; During disposable welding, because the difference of the material thickness of two ends header and core, it is bigger that the heat that is absorbed during welding also differs in soldering oven for radiator; Temperature setting and control relative difficulty in the soldering furnace are bigger; Very easily causing 1) burning appears in core when having satisfied the welding of header and O type pipe, produces " waisting ", and it is bad that fin is meltable etc.; Two ends header scolder does not fuse fully when 2) satisfying the welding of core, occurs lack of penetration and leakage that produce.In addition, when radiator afflux pipe and radiating tube erection welding, can't might cause flat pipe phenomenon, cause postwelding to leak as the radiator of plastic-aluminum structure to the radiating tube enlarging.
Summary of the invention
To the problem in the above automobile radiators production, the utility model purpose is, a kind of automobile radiators assembly is provided, and adopts the radiator of this structure, and the problem that exists in the production of above-mentioned full aluminium automobile radiators is solved.
The technical scheme of the utility model is:
A kind of automobile radiators assembly; Comprise header, radiating tube and fin; Said radiating tube and header are welded to connect, and pore communicates, and said radiating tube and fin are welded to connect; It is characterized in that: be positioned at outside radiating tube and adopt many mouthfuls of radiating tubes, be provided with reinforcement in the tube chamber of said many mouthfuls of radiating tubes.
Described automobile radiators assembly is characterized in that: be positioned at each 1～10 radiating tube of outside two ends and adopt many mouthfuls of radiating tubes.
Described automobile radiators assembly is characterized in that: be provided with 1～5 reinforcement in the said many mouthfuls of radiating tube tube chambers.
The utility model automobile radiators assembly; Reasonable in design, adopt many mouthfuls of radiating tubes that are provided with reinforcement, can be when the disposable welding of radiator; Overcome the flexural deformation that the welding of radiating tube and fin produces radiating tube fully; And the flat pipe problem when having overcome the welding of radiating tube and header, thereby guarantee welding quality, do not produce waster.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Accompanying drawing 1 is an automobile radiators assembly structure sketch map;
The employing prior art radiating tube that accompanying drawing 2 is analysed and observe to amplification for automobile radiators assembly A-A shown in Figure 1 is during with the fin welding, and radiating tube produces and is out of shape sketch map;
The utility model that accompanying drawing 3 is analysed and observe to amplification for automobile radiators assembly A-A shown in Figure 1 adopts many mouthfuls of radiating tube structures and radiating tube and fin welding situation sketch map;
In the accompanying drawing: the 1-radiating tube; The outside radiating tube of 1a-; 1a1-O shape radiating tube; Many mouthfuls of radiating tube 1a2a-of 1a2-reinforcement; 1b-internal heat dissipating pipe; The 2-header; The 3-fin; The 4-side plate; 5-is out of shape the slit.
The specific embodiment
As shown in Figure 1, once-through type, pipe type automobile radiators assembly comprise header 2, radiating tube 1 and the fin 3 of both sides; 2 sealings are welded to connect said radiating tube 1 with header; Its pore communicates, and water of radiation stream gets into a side header 2 and flows through radiating tube 1 through the inlet opening, gets into opposite side header 2; The fin 3 that radiating tube 1 external welding connects; To flowing through the effect of the distribute heat that the lifting of radiating tube 1 heat radiation current wants, the side plate 4 that heat radiator assembly two ends outermost is fixedly connected with header 2 plays a part radiating tube 1, fin 3 etc. are protected.
Because the prior art radiator adopts O shape radiating tube 1a1; In soldering oven, in the disposable welding, when each fin 3 is welded to connect with many radiating tube 1a1 respectively, strain radiating tube 1a1 from radiator middle part (inside) toward limit portion (outside); And radiating tube 1a1 two ends the fixing of itself and header 2 welding that receive to loose; Then make radiating tube 1a1 produce flexural deformation, particularly the radiating tube 1a of limit portion (outside) as shown in Figure 2, the influence of more whole accumulated deformation is arranged with respect to the radiating tube 1b of middle part (inside); Outside its flexural deformation of radiating tube 1a is then all the more serious; This flexural deformation forms distortion slit 5, promptly makes fin 3 and radiating tube 1a1 to weld, thereby causes leakage.
As shown in Figure 3; The utility model automobile radiators assembly; Adopt many mouthfuls of flat tube 1a2, be provided with 1～5 (present embodiment is 3) elongated reinforcement 1a2a in its tube chamber, strengthened the counter-bending deformation intensity of radiating tube 1a2 greatly; In welding, avoid being out of shape the appearance of slit 5 situations, the flat pipe problem when having overcome O shape radiating tube 1a1 and header 2 welding.Simultaneously,, impel the caloric receptivity of core and two header ends to tend to balance, alleviated meltable bad of core body " waisting " and fin widely because the many mouthfuls of flat tubes that limit portion adopts have increased caloric receptivity when welding; Take all factors into consideration the factor such as overall weight, water flowing resistance, material cost of heat radiator assembly; Each 4 radiating tube 1a of the most yielding limit portion (above and below shown in Figure 1) adopt many mouthfuls of radiating tube 1a2 to present embodiment at automobile radiators assembly two ends; Or look concrete condition, with many mouthfuls of radiating tube 1a2 of each 1～5 radiating tube 1a employing of radiator two ends limit portion.
Except that the above, the utility model can also have other embodiments, this not superfluous one by one stating.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all belong to the protection domain of the utility model requirement.
