Hydraulic oil auxiliary heat dissipation system and construction machinery

Abstract

The invention provides a hydraulic oil auxiliary cooling system and a construction machine, the hydraulic oil auxiliary cooling system includes a water tank, a hydraulic oil tank and a radiator, the hydraulic oil tank is fixed on one side of the water tank; the radiator It communicates with the hydraulic oil tank through an oil inlet pipe and an oil return pipe, and is used to cool down the hydraulic oil in the hydraulic oil tank; wherein, the radiator has a fan, and the blowing end of the fan faces the hydraulic oil tank, so A water outlet pipe is connected to the water tank, and the water outlet end of the water outlet pipe extends toward the blowing end of the fan for spraying the hydraulic oil tank. The construction machine has the above hydraulic oil auxiliary cooling system. The hydraulic oil auxiliary heat dissipation system of the present invention uses the wind force of the fan on the radiator to make the water flowing out of the water tank form water mist to spray the hydraulic oil tank, thereby realizing enhanced cooling of the high-temperature hydraulic oil in the system circuit with low energy consumption. cooling.

Description

technical field [0001] The invention relates to the field of building construction equipment, more specifically, to a hydraulic oil auxiliary cooling system and a construction machine. Background technique [0002] The current concrete pumping construction machinery usually uses a radiator to cool the hydraulic system. The radiator in the prior art usually uses a gear motor or an electric motor to drive the radiator, and the cooling capacity of the radiator is usually limited by the flow rate and pressure resistance of the radiator. , only a small part of the hydraulic system can be cooled to return oil, and most of the high-temperature oil is still directly returned to the oil tank, and then circulated by the oil pump. When the ambient temperature is too high, the cooling capacity of the radiator in the prior art is even more insufficient. [0003] Therefore, it is very necessary to propose a hydraulic oil auxiliary heat dissipation system that has a simple structure and ca...
