The invention relates to a heat dissipation system, and aims to solve the problem that an electronic fan in an existing engineering machinery heat dissipation system is inconvenient to remove dust. The invention provides an engineering machinery heat dissipation system and engineering machinery. The heat dissipation system comprises a wind scooper and an electronic fan installed on the wind scooper. The heat dissipation system is characterized by further comprising a dust removal device, wherein the dust removal device comprises a stop bar installed outside the wind scooper and a driving device connected to the stop bar; the driving device is used for driving the stop bar to move between a fan blade assembly rotating area of the electronic fan and the outer space of the fan blade assembly rotating area, and when the stop bar stretches into the fan blade assembly rotating area of the electronic fan, the stop bar makes limited contact with a fan blade assembly of the electronic fan in order to stop the fan blad
