A first aspect of the invention proposes a cooling nozzle for rectifying a fluid within a piston cooling nozzle.
As shown in fig. 1 and 2, the cooling nozzle in the present embodiment includes a head 1 and a nozzle 2; a first channel 6 is arranged in the spray head 1, a connecting piece 9 is arranged on the spray head 1, and a second channel 7 communicated with the first channel 6 is arranged in the connecting piece 9; one end of the nozzle 2 is arranged on the connecting piece 9, the nozzle 2 is communicated with the second channel 7, and the other end of the nozzle 2 is internally provided with the flow winding piece 3.
