Abstract

The invention discloses a production method of a parallel flow heat exchanger for an automobile air conditioner. The method comprises the steps of collecting main processing, flat tube processing, fin processing, side board processing, core body assembly, core body strapping, blanking cover installation, spot welding before furnace, inspection before furnace, core body correction, flux spraying, core body drying, inspection in the middle of furnace, brazing furnace welding, welding after furnace, fin correction, general assembly, inflation and pressure preservation, in-process inspection, comprehensive treatment of non-conforming products, packaging and stock-in procedures. The production method of the parallel flow heat exchanger for the automobile air conditioner has the advantages that due to the adoption of the spot welding before furnace procedure, the utilization efficiency of a brazing furnace is improved; the product conformity rate is improved through the inspection before furnace, inspection in the middle of the furnace, inspection after furnace and final inspection procedures; the product size consistency is improved through the core body correction procedure. Meanwhile, the method has the characteristics of simple process, low equipment cost, easiness in transformation and the like.

Description

technical field [0001] The invention relates to a production method of a heat exchanger, in particular to a production method of a parallel flow heat exchanger for an automobile air conditioner. Background technique [0002] my country's automobile industry is developing rapidly. Parallel flow heat exchangers are gradually replacing tube-belt and stacked heat exchanger structures because of their high efficiency and compactness. They are the most promising heat exchanger products. However, the current production method of parallel flow heat exchangers for automotive air conditioners has problems such as low production efficiency, poor product dimensional stability, low use efficiency of brazing furnaces, and low yield. Now people are longing for a production method suitable for mass production of parallel flow heat exchangers for automotive air conditioners to solve practical problems. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the obj...
