A double radiator applied to exhaust manifold flange welding

Abstract

The invention discloses a double radiator applied to exhaust manifold flange welding, comprising: a cold water conveying assembly, including an annular cooling position and a first connecting channel connected between adjacent annular cooling positions, the cold water conveying The head and tail ends of the assembly are also provided with water inlets and water outlets respectively; the cold air conveying assembly includes air supply positions corresponding to each annular cooling position and a second connecting channel connected between adjacent air supply positions; the cold air conveying One end of the assembly is also provided with an air inlet; the same side of each air supply position is respectively provided with cooling bins communicating with it, and each cooling bin can pass through the corresponding opening at the center of the annular cooling position; the cooling bins There is an air outlet on the top; it accepts the pedestal, and the cold water delivery component and the cold air delivery component are placed inside it. The invention can avoid the defects caused by the bending deformation of the flange through multiple interactive heat exchanges during the exhaust manifold flange welding process, so as to 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 a double radiator applied to exhaust manifold flange welding. 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...

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
