For vacuum brazing aluminum plate bar cooler, traditional radiator core assembly method is to adopt the width adjustable fixed high baffle on the cast iron platform. After core assembly, professional person has core trimming and use heavy stainless cast steel clamps and long bolts, nuts to fix core. This method is time-consuming and labor-intensive, and cannot make full use of the heating space of vacuum brazing furnace. In order to improve the production efficiency of core assembly and reduce energy consumption, core assembly machine technology has gradually entered the field of aluminum plate fin heat exchanger, plate bar cooler, radiator, which greatly speeds up the core assembly efficiency and increases the loading capacity of brazing furnace. Plate bar cooler core assembly machine is suitable for assembling plate bar cooler cores of various specifications. The core builder for plate bar cooler can easily and flexibly adjust the length, width and height of the cooler…
