[0031] When using the excavator radiator flat tube, if Figure 1 and Figure 2 As shown, the outer side of the circulation pipe 1 is fixedly connected with the ear plate 2, and the support block 3 is welded on the excavator. When the radiator is installed, the circulation pipe 1 drives the ear plate 2 to engage with the support block 3. Combined with the fixing bolt 4, the fixing bolt 4 and the support block 3 as well as the fixing bolt 4 and the ear plate 2 are all threadedly connected, so as to facilitate the positioning between the support block 3 and the ear plate 2, thereby facilitating the installation and positioning of the radiator. The circulation pipes 1 are symmetrically arranged on the left and right sides of the flat tube body 5, and the circulation pipes 1 on the left and right sides are connected to the circulation pipes 1 through the flat tube body 5, the connecting pipe 6, the installation sleeve 7 and the fixing cylinder 9. , and the sealing ring 8 is fitted between the connecting pipe 6 and the mounting sleeve 7, and the sealing sleeve 10 is fitted between the fixing sleeve 9 and the mounting sleeve 7. The sealing ring 8 and the sealing sleeve 10 are provided to improve the sealing performance of the connection between the components, and prevent the coolant from leaking when flowing. The coolant flows from the left circulation pipe 1 through the fixing sleeve 9, the mounting sleeve 7 and the connecting pipe 6 through the flat tube body 5 into the right circulation pipe 1 and flows out. The heat of the coolant in the flat tube body 5 is taken away by the air to realize heat exchange.
