Heat exchange pipe for oil cooler

The invention discloses a heat exchange pipe for an oil cooler. The heat exchange pipe comprises a lubricating oil cooler body, and is characterized in that: the heat exchange pipe is arranged in the lubricating oil cooler body; and the surface of a pipe body of the heat exchange pipe is provided with a radiating fin set which consists of ring-shaped radiating fins in a hoop type expanded connection mode. In the invention, the heat exchange pipe on which the radiating fin set is arranged is adopted in terms of technology in place of a single type light pipe in the prior art; and the quickening of the fluid turbulence is promoted, a heat transfer coefficient value is improved, the effective heat exchange area is increased, and the heat transfer speed is increased through the improvement on the surface shape of the heat exchange pipe. In addition, the volume of a heat exchanger can be greatly reduced by taking a heat transfer pipe which is provided with the radiating fins in the expanded connection mode as a he
