Fixed card buckle is installed to be fixedly connected with limit card block.
Preferably, the backplate is L-shaped, and mounting hole is evenly arranged on the outside of backplate.
Compared with prior art, the beneficial effects of the present invention are: all aluminum car radiator welding side with bilateral water chamber
The fixation fixture block for shunting partition bottom end is inserted into fixed card slot when in use by being equipped with limit card block and fixed card buckle by method
Interior, limit card block is fixed to each other with fixed card buckle, will shunt partition location and installation, the material of partition and lower cover plate is shunted according to automobile
Using welding wire solder flux is prepared, welding wire is welded with the method for soldering with regard to objects such as decontamination, oil, rust matter, and weldment and solder heat are to being higher than
Brazing filler metal fusing point, lower than the temperature of base material fusing point, soak base material using liquid solder, fill play movement and with base material phase counterdiffusion
It realizes connection, partition will be shunted and water chamber is welded, water chamber is separated into intake chamber and water-supplying chamber, brazing deformation is small, connector
Smooth and beautiful appearance is suitable for accurate welding, complexity and the component being made of different materials, uses when upper cover plate is welded with lower cover plate
Submerged-arc welding mode is welded, and welding wire winds junction between upper cover plate and lower cover plate, prevents dust impurity from entering, and is reduced unmelted
The probability that the problems such as conjunction, stomata, slag inclusion and some shape defects occurs.
