Description

Flow channel plate of thermal management system Technical Field The invention relates to the technical field of runner plates, in particular to a runner plate of a thermal management system. Background Along with the transformation of global energy structures and tightening of environmental protection policies, new energy automobiles (including pure electric automobiles, hybrid electric automobiles and the like) become the core direction of high-quality development of the automobile industry, the endurance mileage, the operation safety and the service life of the new energy automobiles become core indexes of market competition, and the thermal management system is used as a central nerve for guaranteeing the stable operation of the core components of the new energy automobiles, so that the comprehensive performance of the whole automobile is directly determined. The main defects of the existing new energy automobile flow channel plate main flow design are as follows: (1) The assembly efficiency is low, the existing new energy automobile runner plate is positioned by adopting a single pin and a clamping groove, the upper, middle and lower bodies are easy to deviate during assembly, manual repeated calibration is needed, the assembly time of a production line is long, the assembly time of a single assembly is high, the positioning structure is disjointed from the assembly flow, the automatic production line cannot be adapted, and the labor cost ratio is high during large-scale production. (2) The welding yield is poor, the existing new energy automobile runner plate has no special flash collecting structure, the molten material overflows the sealing surface and the locating surface of the runner plate which are easy to adhere during welding, so that the subsequent assembly gap is overlarge and the sealing is invalid, the flash is required to be cleaned manually, the subsequent process cost is increased, the welding edge is compact in design, the outer ring flange is fully welded, the welding path is long, the process is complex, stress concentration at the welding position is easy to occur due to the accumulation of the molten material, the welding seam is cracked after long-term use, the sealing performance of the runner plate is influenced, impurities are not thoroughly cleaned by the flash, the pipeline is blocked after the flash enters the runner, and the fluid transmission efficiency of the new energy automobile thermal management system is influenced. (3) The process suitability is weak, the process is mainly designed in an integral or split type simply, the structural design only meets the basic functions of fluid transmission, sealing and the like of a runner plate, the suitability of a mass production process is not considered, so that 'laboratory samples are qualified, the mass production yield is low', the structures such as positioning, welding and assembling are mutually independent, the cooperative design is not realized, a certain link optimization can cause new problems (such as positioning accuracy reduction after optimizing welding edges) in other links, the whole process optimization is difficult to realize, the later transformation aiming at the mass production problem needs to be performed with mold opening again, the mold transformation cost is high, the period is long, and the product research and development and production cost is increased.
