The utility model relates to a forced air cooling hydraulic pressure station with secondary heat dissipation pipeline, switching valve set installs the front end at the oil tank up end, and the rear end installation of fuel feeding power supply, oil tank up end is installed to the oil tank up end at switching valve set rear blower housing, this blower housing be towards the outside of oil tank installation radiator, and this blower housing is towards at least one fan of interior side -mounting of oil tank, and oil tank up end between fuel feeding power supply and blower housing sets up has a plurality of secondary heat dissipation pipeline that bend in the vertical orientation. The utility model discloses in, fan face direction on the oil tank sucks the cold air, then is blown out by radiator outwards, makes the air current measured time take away other hydraulic component's of oil tank up end heat like this, and secondary heat dissipation pipeline can make thicker pipeline, also can set up more multilayer, the fluid speed reduction of advancing like this, messenger's secondary radiating effect is better.
