Abstract

The utility model relates to an improved brazing aluminum tube fin oil cooler, which comprises an outer tube, an inner fin and an inner tube. The composite inner fin is arranged between the outer tube and the inner tube, an aluminum tube nozzle is welded on the outer tube, and the aluminum tube nozzle, the outer tube, the inner fin and the inner tube are welded to be an integral structure. By means of improved end portion structural design and process guarantee of integral brazing of the inner tube and the inner fin, the aluminum tube fin oil cooler obviously promotes heat dispersion of the oil cooler, cost is greatly reduced, strength also meets product standard regardless of slight reduction compared with a copper tube fin oil cooler, and using requirements can be completely met.

Description

Modified model braze welding type aluminum pipe wing oil cooler

Technical field

The utility model relates to a kind of engine motor oil cooler, relates in particular to a kind of modified model braze welding type aluminum pipe wing oil cooler.

Background technique

Machine oil cooler is the significant components on the Motor Vehicle such as automobile, is used for the temperature of cooled engine or transmission system internal lubrication oil, at present; Inner at most automobile radiators, what mainly use is copper pipe formula oil cooler, and the shortcoming of this kind structure mainly is that the cost of raw material is high; Between inner and outer pipe, be provided with fin; The method of managing through rising is inner and outer pipe and internal fin fixedly, because of welding, so heat dispersion is poor.And existing aluminum pipe wing oil cooler two ends ozzle can adopt the aluminium section bar ozzle; This structure has two deficiencies, and the one, internal fin can't extend to the end of oil cooler, because of there not being the internal fin welding; Oil cooler end strength deficiency, the cost of production that is exactly the aluminium section bar ozzle in addition is than higher.

The model utility content

The utility model provides in order to overcome the above problems that a kind of cost of production is low, perfect heat-dissipating, modified model braze welding type aluminum pipe wing oil cooler that intensity is high.

The technological scheme of the utility model is: comprise outer tube, internal fin, interior pipe, be provided with compound internal fin between described outer tube and the interior pipe, welding of aluminum ozzle on the described outer tube, described aluminum pipe mouth, outer tube, internal fin and the interior pipe formula structure that is welded as a whole.

The utility model advantage compared with prior art is:

1) heat dispersion is high: after internal fin and inner and outer pipe adopted brazing mode to be welded as a whole, heat dispersion improved greatly, and the aluminium soldering tubular type oil cooler heat dispersion of same specification will exceed 20% than copper pipe formula;

2) cost of production is low: the cost of single aluminum pipe oil cooler has only 30 ~ 40% of copper pipe formula oil cooler;

3) intensity is high: the mode of employing aluminum pipe mouth and outer tube soldering replaces the mode of aluminium section bar, and internal fin can extend to the two ends of oil cooler like this, and the inner and outer pipes at two ends just can be integrally welded through internal fin, and intensity increases greatly.

The utility model is through improved end construction design and inner and outer pipes and the integral braze-welded technology assurance of internal fin; Adopt aluminium tubular fin type oil cooler significantly to promote the heat dispersion (comparing) of oil cooler with the copper tubular fin type oil cooler of same specification; Cost has also obtained great decline; Descending although intensity is compared with copper pipe wing oil cooler slightly, also is to meet product standard, can satisfy the requirement of use fully.
