Air cooling hydraulic station with secondary heat dissipating pipeline

Abstract

The invention relates to an air cooling hydraulic station with a secondary heat dissipating pipeline. A switch valve group is arranged at the front end of the upper end face of an oil tank; an oil supply power source is arranged on the upper end face of the oil tank at the rear part of the switch valve group; a fan casing is arranged at the rear end of the upper end face of the oil tank; a heat dissipater is arranged at the outer side, facing the oil tank, of the fan casing; at least one fan is arranged at the inner side, facing the oil tank, of the fan casing; and the secondary heat dissipating pipeline with multiple bends in the vertical direction is arranged on the upper end face of the oil tank between the oil supply power source and the fan casing. According to the air cooling hydraulic station disclosed by the invention, the fans suck cold air from the upper end face direction of the oil tank, and then the cold air is blown out by the outward heat dissipater, so that the heat of other hydraulic components on the upper end face of the oil tank can be taken way when air flows; the secondary heat dissipating pipeline can be produced into a thicker pipeline or can be arranged into multiple layers, so that the advancing speed of oil is reduced, and a secondary heat dissipating effect is better.

Description

technical field [0001] The invention belongs to the technical field of improving the oil heat dissipation structure of a hydraulic station, in particular to an air-cooled hydraulic station with a secondary heat dissipation pipeline. Background technique [0002] The hydraulic station is the core of the hydraulic system. It transmits the oil to different hydraulic cylinders through the oil supply power source and the switch valve group to realize different actions to complete functions such as pushing and lifting. Since the oil will generate heat when it works again, especially in the hydraulic system with frequent movements or high pressure, the temperature of the oil will heat up greatly. If the temperature cannot be lowered, it will inevitably affect the stability of the oil. The existing air-cooled The structure of the type heat dissipation method includes: a fan casing 4, a radiator 3 and a circulating power source 9, all of which are installed on the upper surface of th...

AI Technical Summary

Problems solved by technology

In actual use, it is found that since the radiator is located above the fuel tank, the cold air sucked by the outside fan performs heat exchange with the radiator, and the hot air is blown out towards the top of the fuel tank, which not only affects other hydraulic components on the upper end of the fuel tank, but also The cooling effect of the fan needs to be improved
