Problems solved by technology
Use carbon steel joints, the cost is low, but the base part of the oil cooler joints is immersed in the cooling water of the water radiator, which is easy to rust. Although nickel plating is often used, it is still difficult to prevent corrosion
The use of stainless steel joints can improve the anti-rust performance, but the cost increases, and the stainless steel material is difficult to process. It is difficult to process the connecting thread to meet the design requirements, and it is easy to cause oil leakage on the sealing surface

The invention discloses a dissimilar metal combined-type oil cooler joint, which comprises a joint seat, a joint thread body and a joint soldering terminal, wherein the joint thread body is arranged on the joint seat, and the joint soldering terminal is arranged on the contact surface between the joint thread body and the joint seat. The dissimilar metal combined-type oil cooler joint integrates the characteristics of low cost and easiness in machining of a carbon steel joint as well as prominent rust prevention performance of a stainless steel joint, ensures that thread machining is changed from a blind hole to a through hole which is more beneficial to machining, through reasonable parting, and is capable of solving the problems of rusting of the oil cooler joint and oil leakage of the joint seal surface better.
Description
technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a stainless steel plate-fin type engine oil cooler component on an automobile. Background technique [0002] At present, the installation and use methods of stainless steel plate-fin oil coolers on automobiles can be divided into three types: 1. Placed in the engine body, installed on the side of the engine body through the cooler cover; 2. Combined with the spin-on filter The cleaner is connected to the engine by installing connecting bolts; 3. Placed in the upper and lower water chambers of the car radiator, and connected to the radiator through the oil cooler joint. The third way is the most common. Among them, the oil cooler joint is integral, as attached Figure 1 As shown, the material is carbon steel or stainless steel. Carbon steel joints are used at a lower cost, but the base part of the oil cooler joint is immersed in the cooling water of the water radiator, wh...
