Jet engine shell cooled by fuel oil

The invention belongs to the field of liquid cooling heat dissipation, and relates to a jet engine shell cooled by fuel oil, which comprises a cuboid shell body, and the left surface of the shell body is provided with a square through hole which is through left and right; the square through hole is divided into four layers of cuboid-shaped channels at equal intervals through partition plates. The upper surface of the shell body clings to the surface of an engine; a non-uniform lattice structure is arranged in each layer of channel; the left end of the shell body is connected with a fuel oil injection end, and the right end of the shell body is connected with a combustion chamber of an engine, so that fuel oil is injected into the combustion chamber after flowing through the four layers of channels after being injected into the engine shell. Fuel oil enters the channel to cool the engine shell, heat dissipation of an engine can be achieved, fuel oil can be sprayed into a combustion chamber to be combusted, the
