Problems solved by technology

However, the cooling area of ​​the above-mentioned pipe body is limited, and a better oil cooling effect cannot be achieved.
[0004] Secondly, when assembling the oil cooler tube body into an oil cooler, due to the unreasonable structural design, the welding strength is insufficient, so that the working pressure that the oil cooling tube body can withstand during work is small, and the pressure at the inlet and outlet ends of the oil cooling tube body The strength is also weak and cannot meet the requirements of use

Embodiment 1

[0037] Such as Figure 1-3 As shown, the misplaced dotting oil cooler tube of the present invention includes a tube body 1, the thickness of the tube body 1 is 3.0mm, and the width is 10.0mm; A first groove 2 formed by the inward depression of the pipe wall, the lower surface of the pipe body 1 is provided with a plurality of second grooves 3 formed by the inward depression of the pipe wall; the bottom of the first groove 2 and the second groove 3 Bottom welded. The axial direction of the first groove 2 and the axial direction of the second groove 3 are perpendicular to each other, and the included angle between them and the axis of the tube body 1 is 45°.

[0038] The first groove 2 and the second groove 3 are all provided with 6 rows, every 2 rows of the first groove 2 are evenly distributed, the length of the first groove 2 is 1.5mm, and the maximum width is 0.4mm. The number, length and width of the grooves 3 are the same as those of the first groove 2 .

[0039] There ...

Embodiment 2

[0041] Such as Figure 4 As shown, the difference between the misplaced dotted oil cooler tube of this embodiment and the first embodiment is that the inner walls of both sides of the tube body 1 are provided with reinforcing pieces 5 .

Embodiment 3

[0043] Such as Figure 5-6 As shown, the difference between the misplaced dotted oil cooler tube of this embodiment and that of Embodiment 1 is that the tube body 1 is bent from a piece of sheet body, and a first bending portion 6 is provided at the bend of the sheet body. The two free ends of the sheet are respectively provided with a second bending portion 7 and a third bending portion 8 . The first bending part 6 is formed by folding three layers of a sheet body, and the second bending part 7 and the third bending part 8 are formed by folding three layers of two free ends of the sheet body into the tube body 1 , and the heights of the second bending portion 7 and the third bending portion 8 are half of the height of the first bending portion 6, the first bending portion 6, the second bending portion 7, and the third bending portion 8 The thickness is the same after folding. The second bending portion 7 and the third bending portion 8 are closed by high frequency welding. ...

Abstract

The invention discloses a staggered dotting oil cooler pipe which comprises a pipe body; the upper surface and the lower surface of the pipe body are provided with a first groove and a second groove separately, and the first groove and the second groove are perpendicular to each other axially; and sunken reinforcing ribs are further arranged in the pipe body. Reinforcing pieces or bending parts are further arranged at the two ends of the pipe body. The staggered dotting oil cooler pipe is internally provided with a plurality of oil passing channels, and the turbulence effect is improved through cross staggered design, so that the oil cooler pipe can have a better turbulence effect without using inner fins. The staggered dotting oil cooler pipe has higher working pressure, the pressure intensity of the inlet and outlet ends of the oil cooler pipe can be guaranteed, and therefore lubricating oil can smoothly pass through the oil cooler pipe. The inner fins are not needed, and the weight of the pipe body is reduced, thereby being favourable to reduction of the overall weight of the oil cooler; and the service life of the oil cooler is prolonged through the high-strength oil cooler pipe. The oil cooler pipe is simple in structure, convenient in installation, high in cooling efficiency of the lubricating oil, and low in raw material cost and has good application prospects.

Description

technical field [0001] The invention relates to the technical field of automobile radiator components, in particular to an oil cooler tube with misplaced dots. Background technique [0002] When the car is running, the temperature of the lubricating oil contained in the gearbox will continue to rise due to the transmission of power. If the temperature of the lubricating oil is too high, it may cause the lubricating oil to boil and lose its lubricating effect, thus making the gears easy to wear. How to ensure The lubricating oil temperature in the gearbox will not be too high, which becomes a very important issue. In the existing structural configuration of automobiles, oil cooler tubes are provided to cool lubricating oil and ensure that the oil temperature is within the normal working range. [0003] The automobile oil cooler in the prior art includes an oil cooler tube body, the oil cooler tube body has inner and outer double-layer tube walls, the tube ends of the inner a...
