It's about the system.

In general, there are several types of heat exchangers, such as a fin tube type, a serpentine type, a drawn cup type, and a parallel flow type, depending on the heat exchange medium, structural characteristics, and working pressure. , The heat dissipation fins used in these heat exchangers include a corrugate type, a flat type, and a louver type.

Among these heat exchangers, the drone cup type is made by braze bonding a tube and a heat dissipation fin joined by forming plates having a tank unit and dimples, and the parallel flow type is a combination of a plurality of tubes in communication with the upper and lower tanks and braze-bonded with a heat dissipation fin interposed between the tubes.

As described above, braze bonding in the process of manufacturing a heat exchanger is performed by being put into a brazing furnace in a state in which the heat exchanger is made by a tube forming plate and a tank made of a material having a clad layer formed on the surface, and then the clad layer is melted.

In other words, braze bonding involves supplying and melting a brazing material (brazing filler metal) that is melted at a temperature below the melting point of the base material between the separated base materials instead of melting the base material to bond the two separated base materials to each other. It is a welding method that completes the joint.

On the other hand, as a brazing furnace system for brazing the heat exchanger as described above, the technology of an aluminum continuous brazing furnace (NBF, Nocolok Brazing Furnace) is applied.

The conventional brazing furnace system as described above has a problem in that it takes a long time to rise from room temperature to 630 degrees Celsius to obtain brazing stability from 580 degrees Celsius, the AL-Clade Melting Point, due to the indirect heating method. Since it has to be configured, a wide installation space is required, and at the same time, there is a problem in that the installation place is limited, such as not being able to install it in a general factory.

In addition, the conventional brazing furnace system has a problem in that the length of the equipment is long, the consumption of electricity is increased, and the use of nitrogen is excessive, so that cost reduction is urgently required.

In other words, in the conventional brazing furnace system to which an aluminum continuous brazing furnace is applied, the product heating time due to indirect heating becomes longer, so the length of the brazing furnace becomes longer. Because it occupies a lot, it is required such as a request for slimming the installation space, and cost reduction by reducing the amount of electricity and nitrogen used is required.

Therefore, at the same time loading and unloading of the brazed object is made easily, the working time can be significantly reduced by applying the direct heating method and the direct cooling method. And research and development of a brazing furnace system capable of compacting the length of the entire facility by reducing the length of the facility according to heating and cooling through the direct cooling method is required.
