Abstract

The invention discloses a water-cooling aluminum alloy airplane hydraulic oil tank. The water-cooling aluminum alloy airplane hydraulic oil tank comprises an oil tank outer tank body and an oil tank inner tank body which are made of aluminum alloy materials, the independent oil tank inner tank body is arranged in the inner part of the oil tank outer tank body, the bottom of the oil tank inner tankbody is fixedly connected with the surface of the lower inner wall of the oil tank outer tank body through an inner tank body supporting seat, a cooling cavity with the periphery which communicates is formed between the oil tank outer tank body and the oil tank inner tank body, a sub-tank body is further arranged in the inner part of the oil tank inner tank body, the lower end of the sub-tank body is fixedly connected with the lower surface of the oil tank inner tank body, the side face of the sub-tank body is fixedly connected with the side face of the oil tank inner tank body, a concentric-square-shaped sub-cooling cavity is formed in the inner part of the sub-tank body, and the sub-cooling cavity communicates with the cooling cavity and filled with flowing non-Newtonian fluid cooling liquid. According to the structure, the heat dissipation effect is improved, and the water-cooling aluminum alloy airplane hydraulic oil tank has the cooling and heat dissipation functions and has theanti-impact performance at the same time.

Description

technical field [0001] The invention relates to the technical field of fuel tanks, in particular to a water-cooled aluminum alloy aircraft hydraulic fuel tank. Background technique [0002] Aircraft hydraulic oil tanks are an important part of aircraft flight. Its main purpose is to store liquid medium, supply enough oil, and at the same time play the role of heat dissipation, separation of air in liquid medium and precipitation of impurities in liquid medium. The quality of the fuel tank design directly affects the reliability of the hydraulic system, and even affects the flight performance and flight safety of the aircraft. The oil tank must not be overheated. Overheating will cause the oil in the oil tank to overheat. Once the oil is overheated, it will easily cause expansion and affect safety. In addition, if the oil temperature is overheated, it will easily cause errors in the execution of hydraulic components. Therefore, it is necessary to dissipate heat from the fuel...
