Abstract
The utility model relates to a tubular engine oil cooler, and belongs to oil-water oil coolers. The oil cooler mainly comprises an inner tube, an outer tube and radiating fins, and is characterized in that ring-shaped plug sheets are welded in inner cavities at two end parts of the inner and the outer tubes respectively, and the cross section of each plug sheet is U-shaped. The tubular engine oil cooler has the advantages that the cracking phenomenon at end openings is avoided; products with the diameter smaller than 19mm can be processed; the inner cavities are additionally arranged between the inner and the outer tubes, thereby improving the radiating performance; and the oil cooler with convenient processing and high yield is suitable for the processing of various models of oil-water oil coolers.
Description
Technical field
The utility model belongs to the oil-water type oil cooler, particularly a kind of improved tubular type oil cooler.
Background technology
Oil cooler is used for machine oil cooling, the cooling of transmission for vehicles, and the operate as normal of vehicle is played important effect.General employing is chimney cooler now, is made up of interior pipe, outer tube and radiating fin, and the flared type structure is adopted at the two ends of outer tube and interior pipe, and welding forms sealing.But the inner and outer pipes two ends are prone to the phenomenon of splitting after the enlarging, cause product rejection, and the while, less than φ 19mm product, difficulty of processing was big for caliber.
The innovation and creation content
The purpose of this utility model is to provide a kind of tubular type oil cooler of improving the welded encapsulation mode.
The utility model is achieved in that
The tubular type oil cooler mainly comprises interior pipe, outer tube and radiating fin, it is characterized in that: be welded with annular jam respectively in the interior die cavity at interior pipe and outer tube both ends, the cross section of this jam is for being designed to U-shaped.
After the utility model adopts said structure, pass through U type jam welded encapsulation between outer tube and the interior pipe, avoided port to go out to split the generation of phenomenon, can process product less than φ 19mm, increased the interior die cavity between the inner and outer pipes simultaneously, improve heat dispersion, had effect easy to process, that yield rate is high.Be suitable for the processing of various model oil-water type oil coolers.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
In the accompanying drawing, 1 is that interior pipe, 2 is that outer tube, 3 is that jam, 4 is interior die cavity.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
As shown in drawings, the utility model is an oil-water type tubular type oil cooler, and pipe 1, outer tube 2 and radiating fin in mainly comprising are in the interior die cavity 4 that pipe 1, outer tube 2 surrounded in radiating fin was arranged on.At the both ends of interior pipe 1 and outer tube 2, weld a ring body jam 3 respectively in the interior die cavity 4 that surrounds by interior pipe 1 and outer tube 2, these jam 3 sizes are corresponding with interior die cavity 4, the interior die cavity 4 that pipe 1 and outer tube 2 surround in being used to seal.U-shaped is counted in being horizontally set with of described jam 3, and opening is outside.
Add man-hour,, make the outer end of jam 3 and interior pipe 1, outer tube 2 maintain an equal level the end of jam 3 welded encapsulation at interior pipe 1 and outer tube 2.Cancelled former flared type welding manner, easy to process.
During use, be assemblied in the upper tank of automobile radiators or in the water-supplying chamber of cross-flow radiator, be used to cool off transmission oil.
Claims (2)
