The plate radiator has mechanical connections, but most of them are soldered connections. Brazing is the key to the high quality of the plate radiator. It uses the solder with a lower melting point than the parent material to heat it together with the parent material. When the parent material does not melt, the solder is wetted and filled into the connection between the two parent materials. The gap forms a brazing seam. In the gap, the brazing filler metal and the base metal dissolve and diffuse each other, and finally form a firm bond. Copper-phosphorus brazing filler metal or low-silver copper-phosphorus brazing filler metal should be used in brazing connection, so that the welding quality is easy to control.

The brazing quality of plate radiator needs to be judged through destructive tests, only visual inspection can be done, and the internal quality needs to be guaranteed by the brazing process. The brazing process is implemented by the welder's skilled operation technology. Therefore, in order to ensure effective control of the brazing quality, the welder must be trained and qualified before being certified.

Plate radiator is a new type of high-efficiency energy-saving radiator made of high-quality low-carbon precision steel pipes and domestic advanced automatic welding technology. It has clean appearance and inner cavity, elegant shape, free of decoration, good heat dissipation performance, and high pressure bearing capacity. , The inner cavity is treated with high-quality internal anti-corrosion materials, with excellent corrosion resistance, colorful, durable and easy to clean. The header pipes and radiating pipes through which the heat medium of the plate radiator flows are all red copper pipes, which have strong corrosion resistance and no internal anti-corrosion treatment is required.
