High-Frequency Welding of Automobile
First time,POLARIS-ETeK applied the open-close sensor to the high-frequency brazing of the evaporator. Greatly improve the welding efficiency and quality of the evaporator lead-out tube.
In the application of high frequency brazing technology, many users always talk about aluminum discoloration. Many companies want to try high-frequency brazing to replace the current artificial flame brazing or welding methods with huge investment costs (flame turntable and tunnel brazing furnace). High-frequency brazing has attracted the attention of many related companies due to its simple and easy-to-use operation, flexible production, good welding consistency, and beautiful appearance.
Due to the uneven technical capabilities of high-frequency equipment manufacturers, the performance of each manufacturer's power supply is also uneven. The high-frequency brazing of aluminum metal has long been limited by the development status of solder technology, power supply control accuracy, and temperature measurement technology, which has delayed the application of high-frequency brazing in aluminum metal welding. Many users tried high-frequency brazing on aluminum metal in the early stage, but the results were not satisfactory, so that they gave up the high-frequency welding technology prematurely.
polaris-etek pays attention to this demand in the market. In line with the service concept of all for customers, we think about what customers think, and everything is centered on customer benefits. We started to conduct high-frequency brazing of aluminum metal as early as 3 years ago. Research.
Today, we have successfully entered the subdivision of automotive air conditioners, and have successively launched a variety of mature solutions. Such as compressor outlet copper-iron, aluminum interface of receiver dryer, aluminum pipe and aluminum pipe in pipeline, aluminum pipe and joint, single pipe pressure plate, double pipe pressure plate, condenser evaporator lead pipe, muffler, aluminum Distributors, high-frequency welding applications such as battery water cooling belts in new energy vehicles have been widely used on customer sites, and have won unanimous praise from customers and friends.
Today, I will share with you a high-frequency welding case of parallel flow evaporator.
The evaporator is the most important part of the four major parts of refrigeration. The low-temperature condensed liquid passes through the evaporator, exchanges heat with the outside air, vaporizes and absorbs heat, and achieves the effect of refrigeration.
The evaporator is mainly composed of two parts, a heating chamber and an evaporation chamber. The heating chamber provides the heat required for evaporation to the liquid to promote the boiling and vaporization of the liquid, and the evaporation chamber completely separates the gas and liquid phases.
