The left water chamber 2 and the right water chamber 7 are welded with the main board 1 without leakage, and the longitudinal and transverse directions, the outer wall and the inner cavity of the oil cooler 9 exchange heat with the water flow, and the heat exchange efficiency is greatly improved. The heat dissipation requirements of high-power engines can be met without increasing the heat dissipation area and volume of the water tank radiator and the oil cooler 9, thereby reducing the production cost and energy consumption of the automobile;

[0003] The screw head of the oil cooler (engine oil cooler) in the above technical solution is usually made of aluminum. Due to the strength limitation of aluminum material, the thread is prone to slipping during installation, resulting in unstable installation, insufficient connection strength and sealing effect, which not only affects the service life of the oil cooler, but also poses a potential threat to the safety of the car. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a high-strength automobile oil cooler with anti-slip wire in view of the deficiencies of the above-mentioned prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-strength automobile oil cooler with anti-slip wire, comprising an oil cooler body and aluminum joints arranged on both sides of the oil cooler body, which are integrally formed with the oil cooler body and connected, the outer surfaces of the aluminum joints are provided with a rigid reinforcement layer, the outer surface of the rigid reinforcement layer has a threaded structure for connecting other parts of the automobile, and the interior of the aluminum joint has a joint channel for mutual circulation between the oil cooler body and the aluminum joint on the other side.

[0006] By adopting the above technical solution, a rigid reinforcement layer is set on the outer surface of the aluminum joint to replace the aluminum joint for connection with other parts of the car, thereby improving the mechanical strength and pressure resistance of the oil cooler. At the same time, the design of the threaded structure allows connection with other automobile parts, enhancing the installation stability of the oil cooler and avoiding leakage problems caused by thread slippage and joint cracks.

[0007] The above-mentioned anti-slip wire high-strength automobile oil cooler can be further configured as follows: the rigid reinforcement layer is a connecting sleeve made of iron or steel material, the inner wall of the connecting sleeve has an internal thread threadedly connected to the aluminum joint, and the outer wall is provided with the threaded structure.

[0008] With the above technical solution, the material of iron or steel has higher strength and rigidity than aluminum. The internal and external thread design of the connecting sleeve allows the aluminum joint to be fixed in the sleeve by threaded connection. This double-layer structure improves the fastening strength of the connection and reduces loosening caused by vibration.

[0009] The above-mentioned anti-slip thread high-strength automobile oil cooler can be further configured as follows: a thread locking agent or an anaerobic adhesive is filled between the aluminum joint and the connecting sleeve, and the thread structure is an external thread.

[0010] By adopting the above technical solution, the thread locker fills the tiny gaps between the threads and solidifies to form a strong bond, and the anaerobic adhesive uses metal ion catalysis to solidify, thereby enhancing the stability of the threaded connection. The use of thread lockers or anaerobic adhesives enhances the fixation between the aluminum joint and the connecting sleeve, prevents the threaded connection from loosening, and improves the reliability of the connection.

[0011] The above-mentioned anti-slip wire high-strength automobile oil cooler can be further configured as follows: a chamfered portion is provided at the end of the aluminum joint after passing through the connecting sleeve, and the outer diameter of the chamfered portion gradually widens along the direction from the end to the oil cooler body and abuts against the connecting sleeve.

[0012] By adopting the above technical solution, the chamfer design at the end of the aluminum joint provides a smooth transition area, which reduces stress concentration during installation. The design of the chamfer reduces sharp edges and avoids material fatigue caused by local stress concentration. At the same time, the offset structure between the chamfer and the connecting sleeve further fixes the connecting sleeve on the aluminum joint and seals the end gap between the aluminum joint and the connecting sleeve, which helps to form a better sealing effect.

[0013] The above-mentioned anti-slip wire high-strength automobile oil cooler can be further configured as follows: a sealing ring seat is provided between the aluminum joint and the oil cooler body, the diameter of the sealing ring seat is larger than the diameter of the connecting sleeve, the aluminum joint is connected to the oil cooler body through the sealing ring seat, and the surface of the sealing ring seat facing one end of the aluminum joint has an annular groove for installing a sealing ring.

[0014] By adopting the above technical solution, the sealing ring seat is used as an intermediary structure, and the sealing ring is installed through the annular groove thereon, so that when it is subsequently installed on the automobile oil cooling system, a sealed connection is achieved, preventing the leakage of lubricating oil and ensuring the normal operation of the oil cooler.

[0015] The above-mentioned anti-slip wire high-strength automobile oil cooler can be further configured as follows: the chamfered portion is processed by blunting the sharp angle.

[0016] By adopting the above technical solution, the sharp-angle chamfering treatment makes the edge of the chamfered portion smoother, reduces the stress concentration and potential crack problems caused by the sharp edge, and enhances the integrity of the structure.

[0017] The above-mentioned anti-slip wire high-strength automobile oil cooler can be further configured as follows: the oil cooler body includes an inner tube and an outer tube sleeved on the outside of the inner tube, the inner wall of the inner tube has an internal channel for cooling water to pass through, and there is an external channel between the outer tube and the inner tube for the lubricating oil to be cooled to pass through, the internal channel and the external channel are independent of each other, and the external channels are provided with lubricating oil through holes that are mutually connected to the joint channels at the corresponding aluminum joints of the external channels, and cooling water through holes that are connected to the internal channel are provided at both ends of the inner tube.

[0018] By adopting the above technical solution, the design of the inner tube and the outer tube forms two independent channels, so that cooling water and lubricating oil can flow simultaneously without interfering with each other, thereby improving the cooling efficiency.

[0019] The above-mentioned anti-slip wire high-strength automobile oil cooler can be further configured as follows: the wall thickness of the inner tube and the outer tube is 1 mm, the outer diameter of the inner tube is 13.5-19.5 mm, and the outer diameter of the outer tube is 19-25 mm.

[0020] By adopting the above technical solution, the wall thickness and outer diameter of the inner tube and the outer tube can be accurately controlled, which ensures the strength and cooling efficiency of the oil cooler and meets different installation requirements.

[0026] like Figure 1-Figure 4 As shown, a slip-proof high-strength automobile oil cooler comprises an oil cooler body 1 and aluminum joints 2 arranged on both sides of the oil cooler body 1 and formed integrally with the oil cooler body 1 and communicated with the oil cooler body 1. The outer surfaces of the aluminum joints 2 are provided with iron connecting sleeves 3. The outer surface of the connecting sleeve 3 has an external thread 31 for connecting with other parts of the automobile, and the inner wall has an internal thread 32 threadedly connected to the aluminum joint 2. A thread locking agent is filled between the aluminum joint 2 and the connecting sleeve 3. The aluminum joint 2 has a joint channel 21 for mutual circulation between the oil cooler body 1 and the aluminum joint 2 on the other side. After the end of the aluminum joint 2 passes through the connecting sleeve 3, a chamfered portion 22 is provided. The outer diameter of the chamfered portion 22 gradually widens along the direction from the end to the oil cooler body 1, and It abuts against the connecting sleeve 3, thereby restricting the connecting sleeve 3 on the aluminum joint 2. A sealing ring seat 4 is provided between the aluminum joint 2 and the oil cooler body 1. The diameter of the sealing ring seat 4 is larger than the diameter of the connecting sleeve 3. The aluminum joint 2 is connected to the oil cooler body 1 through the sealing ring seat 4. The surface of the sealing ring seat 4 facing the end of the aluminum joint 2 has an annular groove 41 for installing the sealing ring. When the annular groove 41 is connected to the automobile oil cooling system, a circular sealing ring of high temperature and high pressure resistant hydrogenated nitrile rubber is used as a sealing medium inside. The compression resilience of the medium is utilized to solve the sealing problem of the components. The sealing ring seat 4 and the oil cooler body 1 are made of aluminum alloy as a whole, which not only improves its corrosion resistance, but also reduces the cost and makes welding processing more convenient.

[0027] like Figure 1-Figure 4As shown, the oil cooler body 1 includes an inner tube 5 and an outer tube 6 sleeved on the outside of the inner tube 5. The inner wall of the inner tube 5 has an internal channel 51 for cooling water to pass through. There is an external channel 61 for the lubricating oil to be cooled to pass through between the outer tube 6 and the inner tube 5. The internal channel 51 and the external channel 61 are independent of each other and are not connected to each other. The external channel 61 is provided with a lubricating oil through hole 62 that is connected to the joint channel 21 at the corresponding aluminum joint 2. Both ends of the inner tube 5 are provided with cooling water through holes 52 that are connected to the internal channel 51. When in use, the two aluminum joints 2 are respectively used as a lubricating oil inlet head and a lubricating oil outlet head. The connecting sleeve 3 includes but is not limited to 12*1 or 14*1 specification threads. The cooling water through holes 52 are respectively used as a cooling water inlet head and a cooling water outlet head. After the oil cooler is installed and connected, its cooling water flows through the internal channel 51 of the oil cooler body 1 to exchange heat with the lubricating oil in the external channel 61. The water flow direction is opposite to the oil flow direction, forming convection, thereby greatly improving the heat exchange and achieving the oil cooling effect.
