Hasp type radiator edge plate

Abstract

The invention provides a hasp type radiator edge plate. The hasp type radiator edge plate comprises a welding panel, the two sides of long edges of the welding panel are bent vertically upwards to form turning plates, the two sides of short edges of the welding panel are bent vertically upwards and the top ends of the parts which are bent vertically upwards of the two sides of the short edges of the welding panel are bent vertically towards the outer portion of the welding panel to form pressing heads, the welding panel and the turning plates are all provided with grooves, and the grooves in the welding panel and the turning plates communicate with each other to form expansion slots. By means of the hasp type radiator edge plate, the mechanical strength of the radiator edge plate can be enhanced, the radiator overall welding effect is improved, the fin band drop phenomenon is reduced, and the radiator internal stress can be released more easily and effectively, the radiator strength isguaranteed, and the radiator service life is prolonged.

Description

technical field [0001] The invention relates to the field of radiator side plates, in particular to a buckle type radiator side plate. Background technique [0002] With the development of the automotive air-conditioning industry, the heat exchanger is becoming more and more lightweight, and the thickness of the raw materials used is getting thinner and thinner, which also makes the product strength gradually decrease. Therefore, how to increase the product strength on the basis of existing materials is an urgent need to consider. of. At present, the main and side plate assembly methods of radiators mainly include lap-welding type, plug-in type, and snap-on type. Phenomena such as fin stripping. In addition, the heat sink will also generate stress during brazing and use, so the stress needs to be released in time, otherwise it will easily cause the heat sink to deform and reduce the service life of the heat sink. The current common method to solve the stress effect of rad...

In addition, the heat sink will also produce stress during brazing and use, so it is necessary to release the stress in time, otherwise it will easily cause the heat sink to deform and reduce the service life of the heat sink

The current common method to solve the stress effect of radiators is to saw off the side panels directly, but this method has several disadvantages: ① Some radiator side panels have many mounting holes, and the surrounding area of ​​the mounting holes is easily weakened when sawing off the side panels strength, and even destroy the installation hole; ②The sawing gap of the side plate is small, only the thickness of the saw blade, and the stress existing in some large radiators cannot be fully released; ③The side plate will inevitably be damaged when the side plate is sawed. The fins at the sawn part of the side plate are easy to saw the flat tube, causing leakage, which directly leads to the scrapping of the radiator
