In the existing automobile structure configuration, an oil cooler pipe is arranged for cooling lubricating oil, and the oil temperature is ensured to be within a normal working range.
The automobile oil cooler in the prior art comprises an oil cooler pipe body, wherein the oil cooler pipe body is provided with an inner double-layer pipe wall and an outer double-layer pipe wall, the pipe ends of the inner double-layer pipe wall and the outer double-layer pipe wall are sealed and sealed, an oil passing cavity is defined in the middle of the inner double-layer pipe wall and the outer double-layer pipe wall, one end of the outer pipe wall of the oil cooler pipe body is provided with an oil inlet, the other end of the outer pipe wall of the oil cooler pipe body is provided with an oil outlet. However, the cooling area of the pipe body is limited, and a better oil cooling effect cannot be achieved.
Secondly, when assembling the oil cooler body into the oil cooler, because structural design is unreasonable, lead to welding strength not enough for the operating pressure that the during operation can bear of oil cooling body is less, and the pressure intensity of oil cooling body business turn over end is also relatively weak, can not satisfy operation requirement. Therefore, the application strength of the pipe body of the oil cooler is enhanced, and the key for improving the performance of the oil cooler is realized.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides an oil cooler pipe with staggered dotting.
In order to achieve the purpose, the invention provides the following technical scheme:
the staggered dotting oil cooler pipe comprises a pipe body, wherein a plurality of first grooves formed by inwards sinking pipe walls are formed in the upper surface of the pipe body along the axial direction of the pipe body, and a plurality of second grooves formed by inwards sinking pipe walls are formed in the lower surface of the pipe body; the bottom of the first groove is welded with the bottom of the second groove;

when n is equal to 1, 1 reinforcing rib is arranged between the two rows of first grooves, the reinforcing ribs are formed by inwards sinking the pipe body, and the bottoms of the reinforcing ribs are abutted against the inner wall of the pipe body;
when n is more than or equal to 2, n reinforcing ribs are arranged on the pipe body, 1 reinforcing rib is arranged at every 2 rows of first grooves, and the sinking directions of the adjacent 2 reinforcing ribs are opposite.
Preferably, the length of the first groove is 0.5-1.5 mm.
Preferably, the width of the first groove is 0.2-0.8 mm.
Preferably, the width of the pipe body is 10-250mm, and the thickness is not less than 3 mm.
Preferably, the concave surfaces of the reinforcing ribs are attached to each other.
Preferably, the inner walls of the two sides of the pipe body are provided with reinforcing sheets.
Preferably, the body is formed by a lamellar body bending, and the department of buckling of lamellar body is equipped with first kink, and 2 free ends of lamellar body are equipped with second kink and third kink respectively.
Preferably, the first bent part is formed by folding 2-6 layers of the sheet body.
Preferably, the second bending part and the third bending part are formed by folding 2-6 layers of the 2 free ends of the sheet body into the pipe body, the heights of the second bending part and the third bending part are half of the height of the first bending part, and the number of folding layers and the folding thickness of the first bending part, the second bending part and the third bending part are the same.
Due to the adoption of the technical scheme, the invention has the following beneficial effects:
1. the existing oil cooler pipe is formed by inserting fins into a common welded aluminum pipe (as shown in fig. 7) and then assembling the pipe into an oil cooler for use. This kind of pipe type pressure resistance is weak, and the body middle part receives extrusion deformation easily, and the oil cooler intensity that the assembly formed is poor, and inner fin easily rocks, influences the heat transfer effect.
The staggered dotting oil cooler pipe is characterized in that grooves in staggered directions are arranged on the upper surface and the lower surface of a pipe body, the bottoms of the upper groove and the lower groove are in contact, hot oil passes through an incompletely-closed channel formed by the reinforcing rib and the adjacent first groove and second groove, or the reinforcing rib and the reinforcing rib pass through the side wall of the pipe body. The existing dotting oil cooler pipe is dotted into round points, the welding is easy to be misaligned, the welding point is small, and even two points possibly welded are impacted to be separated if the working pressure is too high. The design of cross dislocation can let the contact point of recess bottom can accurate contact, improves the seam rate, guarantees the normal work of body. And the cross-shaped staggered dotting design enhances the turbulence effect, so that the oil cooler pipe has a better turbulence effect without using inner fins, the weight of the pipe and the weight of the oil cooler are reduced, and the heat exchange efficiency is not reduced. In addition, the oil cooler pipe is also provided with a reinforcing rib, on one hand, the strength of the pipe body is enhanced by using the material of the pipe body, the external volume of the pipe body is not increased, on the other hand, a complete/incomplete oil passing channel can be formed, hot oil is further divided into smaller turbulence, and the phenomenon that the oil cooler vibrates due to the overlarge impact of the flowing of the hot oil on the pipe body is avoided.
2. Present oil cooler is taken both sides to weld enhancement strip and upper and lower backplate at the heat dissipation, forms by independent lamellar body and heat dissipation area welding promptly (like fig. 8), and the welding seam is many, and the structure is complicated, and production technology is loaded down with trivial details, and is inefficient, takes place easily at the use leakage, warp scheduling problem. The invention also arranges the reinforcing sheets at the two ends of the pipe body, which can be directly connected to replace the reinforcing strips and the upper and lower guard plates, and the oil cooler pipe of the invention replaces the oil cooler with the old structure shown in figure 7, so the volume is greatly reduced, the pipe body is formed by bending one aluminum alloy metal sheet body at one time, the material is light, the bending is easy to realize in production, the processing time is greatly saved, the production efficiency is high, the integral strength of the pipe body is high, and the leakage is not easy to occur in the using process. In addition, the oil cooling pipe with the structure can also be used for assembling a common oil cooler.
3. The invention can also design bending parts on two sides of the pipe body, wherein the bending parts are formed by folding 3 times the sheet body towards the inside of the pipe body, and the bending parts are obtained by staggering 2U-shaped openings and then folding and extruding. The kink can guarantee the intensity of body under the less condition of the ascending thickness of assurance body width direction equally, can have great operating pressure when assembling the oil cooler pipe of this structure into the oil cooler to guarantee the pressure intensity of pipe business turn over end, make lubricating oil flow in and flow out smoothly.
Therefore, when the staggered dotting oil cooler pipe is assembled into an oil cooler, the staggered dotting oil cooler pipe has higher working pressure during use, and can ensure the pressure intensity of the inlet end and the outlet end of the oil cooler pipe, so that lubricating oil can smoothly flow in and flow out. And need not to use the inner fin, reduced the manufacturing material of whole body, reduced the weight of body, be favorable to reducing the whole weight of oil cooler, practiced thrift manufacturing cost, the oil cooler pipe of high strength has also prolonged the life of oil cooler. The invention has the advantages of high strength, capability of bearing larger working pressure, simple structure, convenient installation, high cooling efficiency of lubricating oil, low cost of raw materials and good application prospect.
