An Exhaust Manifold Flange Welding Radiator

Abstract

The invention discloses an exhaust manifold flange welded radiator, comprising: a cold water delivery assembly, including cooling positions arranged in the longitudinal direction and connecting passages connected between adjacent cooling positions, the two ends of the cold water delivery assembly Water inlet and water outlet are also respectively provided at the end; the receiving platform is provided with accommodating space corresponding to the cold water conveying assembly, the accommodating space includes an accommodating port matched with the cooling position and accommodating with the The accommodating groove of the connecting channel; the two ends of the receiving pedestal are respectively provided with perforations connected to the accommodating space; the water inlet joint, which can be detachably connected with the water inlet; and, the water outlet joint, which can Detachable connection to water outlet. The invention can effectively cool down the exhaust manifold flange through multiple interactive heat exchanges of cold air and cold water during the welding process of the exhaust manifold flange, avoid defects caused by bending deformation of the flange, and ensure the flatness of the finished product.

Description

technical field [0001] The invention relates to the field of automobile production and manufacturing, in particular to an exhaust manifold flange welding radiator. Background technique [0002] The exhaust manifold is connected to the cylinder block of the engine, and gathers the exhaust of each cylinder into the exhaust manifold, with divergent pipelines. When the generator exhaust is too concentrated, there will be mutual interference among the cylinders, that is, when a certain cylinder exhausts, it happens to encounter the undischarged exhaust gas from other cylinders, which will increase the exhaust resistance. , thereby reducing the output power of the engine. In order to reduce the exhaust resistance as much as possible and avoid mutual interference between the cylinders, the solution is to separate the exhaust of each cylinder as much as possible, one branch for each cylinder, or one branch for two cylinders, and make each branch as long as possible and independent ...

Problems solved by technology

[0005] However, after the stainless steel flange is stamped and formed, there is a lot of internal stress inside the material. During the welding process with the exhaust manifold, due to the high temperature, the stainless steel flange is released from the internal stress of the material and the thermal deformation of the material. Under the joint influence, its flatness is difficult to meet the design requirements, resulting in the need for subsequent grinding treatment, increasing production costs
