Conventional radiators cool air by increasing the heat transfer area by increasing the number of fins per unit length (FPDM, Fin per decimeter) in order to increase the amount of heat transfer. However, when the heat transfer amount is increased by increasing the number of pins per unit length, the space between the pins is reduced, thereby increasing the pressure drop generated while air passes therethrough.

In addition, in the conventional radiator, a fin made by processing an aluminum thin film having a thickness of less than 0.1 mm is joined to the radiator tube by brazing to increase the heat transfer area. However, thin pins joined through brazing are vulnerable to external impact, heat exchange does not occur in the area where the pin is damaged, and a new pin must be brazed to the area to repair the area where the pin is damaged. There is a disadvantage that it is difficult for ordinary people to repair on their own because they must be joined through.

However, the radiator according to the present invention is applied with a fin having a multi-layer structure, and the air flow path and heat transfer area in the radiator are increased through the multi-layer structure, thereby solving the problem of pressure drop and difficulty in repair of the conventional radiator. .
