Dual radiator applied to exhaust manifold flange welding

Abstract

The invention discloses a dual radiator applied to exhaust manifold flange welding. The dual radiator comprises a cold water conveying assembly, a cold air conveying assembly and a bearing pedestal, wherein the cold water conveying assembly comprises annular cooling positions and first linkage channels connected between the adjacent annular cooling positions; a water inlet and a water outlet are further formed in the head end and the tail end of the cold water conveying assembly correspondingly; the cold air conveying assembly comprises air supply positions corresponding to the annular coolingpositions and second linkage channels connected between the adjacent air supply positions; an air inlet is further formed in one end of the cold air conveying assembly; cooling bins communicating with the air supply positions are arranged on the same side faces of the air supply positions correspondingly, and the cooling bins can penetrate through penetrating openings in the centers of the corresponding annular cooling positions; air outlets are formed in the tops of the cooling bins; and the cold water conveying assembly and the cold air conveying assembly are placed in the bearing pedestal.According to the dual radiator, through multiple times of interaction heat exchange in the exhaust manifold flange welding process, the defects caused by bending deformation of flanges are avoided, and accordingly the flatness of finished products is guaranteed.

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
