Description

Technical Field

[0001] The invention relates to the field of radiator side plates, in particular to a buckle-type radiator side plate. Background Art

[0002] With the development of the automotive air-conditioning industry, heat exchangers are becoming more and more lightweight, and the thickness of the raw materials used is becoming thinner and thinner, which also makes the product strength gradually reduced. Therefore, how to increase the product strength based on the existing materials is currently an urgent consideration. The current main assembly methods of the main and side panels of the radiator are lap welding, insertion and buckle. These assembly methods require the side panels to have high mechanical strength, otherwise the radiator is prone to bending and deformation at both ends and the fins at the four corners falling off. In addition, the radiator will also produce stress during brazing and use, so it is necessary to release the stress in time, otherwise it is easy to cause the radiator to deform and reduce the service life of the radiator. The common method to solve the stress effect of radiators in current production is to directly saw off the side panels, but this method has several disadvantages: ① Some radiators have many mounting holes on the side panels, and it is easy to weaken the strength around the mounting holes or even damage the mounting holes when sawing off the side panels; ② The gap when the side panels are sawed off is small, only the thickness of the saw blade, and the stress existing in some larger radiators cannot be fully released; ③ When the side panels are sawed off, the fins at the sawed-off point of the side panels will inevitably be damaged, and it is easy to saw into the flat tubes, causing leakage, which directly leads to the scrapping of the radiator.
