    • The present invention relates to an air fin of a radiator for construction machinery, which is capable of maximizing the heat exchange performance thereof while unaffected by foreign matters such as sand, yellow dust, etc. frequently generated in a construction site and which is capable of minimizing a pressure drop amount (Δp) and maximizing a heat exchange amount (Q) while completely unaffected by the foreign matters. According to the present invention for the above effects, each of multiple air fins installed in the heat radiation lines of a radiator for construction machinery has a main body having: a V-shaped cross section symmetrically tilted; and curved parts formed longitudinally, and mutually alternating on at least one portion. Therefore, the air fins according to the present invention are capable of maximizing the heat exchange performances thereof while unaffected by foreign matters such as sand, yellow dust, etc. frequently generated in a construction site and are capable of minimizing a pressure drop amount (Δp) and maximizing a heat exchange amount (Q) while completely unaffected by the foreign matters.
    • 本发明涉及一种用于工程机械的散热器的空气翅片,其能够在不受施工现场常常产生的诸如沙子,黄尘等的异物影响的同时最大化其热交换性能,并且能够 使压降量(Δp)最小化,并最大化热交换量(Q),同时完全不受异物的影响。 根据本发明,为了实现上述效果,安装在工程机械用散热器的散热线中的多个散热片的主体具有:V字状的横截面对称倾斜的主体; 并且弯曲部分纵向地形成,并且在至少一个部分上相互交替。 因此,根据本发明的散热片能够最大化其热交换性能,同时不受施工现场经常产生的诸如沙子,黄尘等异物的影响,并且能够最小化压降量(Δp )并且最大化热交换量(Q),同时完全不受异物的影响。
