[0002] A fuel oil exchange cooling device needs to be designed on small aero-engines. The fuel oil radiator needs to connect the fuel to the fuel pump, and after pressurization, it flows into the fuel oil radiator and the oil to complete heat exchange; at the same time, it needs A one-way valve is designed separately outside the radiator to prevent lubricating oil from entering the engine when the engine is parked. The structure is more complicated, which increases the volume and quality of the entire engine.
In addition, sometimes due to the large amount of impurities in the fuel oil, the radiator will be accidentally blocked, causing the oil passage to be blocked or even completely blocked. , so that the engine cannot work normally, and even lead to accidents

Embodiment Construction
[0008] As shown in the figure, the fuel oil radiator structure includes a shell 1, a heat exchange structure 5, a lubricating oil inlet valve 2, a lubricating oil outlet valve 3, and a fuel oil inlet valve 4. The fuel oil circuit and lubricating oil are arranged in the shell 1. Oil circuit: a lubricating oil inlet valve 2 is set on the lubricating oil inlet 7 oil way, and a branch oil way is set on the oil way behind the lubricating oil inlet valve 2, one way flows through the heat exchange structure 5 and connects with the lubricating oil outlet 6, and the other way After setting the lubricating oil outlet valve 3, it is connected with the lubricating oil outlet 6; the fuel oil inlet 8 of the fuel oil circuit is provided with a branch oil circuit, one way flows through the heat exchange structure 5 and connects with the fuel outlet 9, and the other way passes through The fuel oil inlet valve 4 is connected with the fuel oil outlet 9; the lubricating oil inlet valve 2, the lubr...

The invention relates to a fuel and slide oil radiator structure. The structure comprises a shell, a heat exchange structure, a slide oil inlet valve, a slide oil outlet valve and a fuel oil inlet valve. A fuel oil path and a slide oil path are arranged in the shell, branch oil paths are arranged at the position, behind the slide oil inlet valve, of the slide oil path, one path flows through the heat exchange structure and is connected with a slide oil outlet, the other path passes through the slide oil outlet valve and then is s connected with the slide oil outlet, branch oil paths are arranged on a fuel oil inlet oil path of the fuel oil path, one path flows through the heat exchange structure and is connected with a fuel oil outlet, and the other path passes through the fuel oil inlet valve and then is connected with the fuel oil outlet. The fuel and slide oil radiator structure is simple and compact, obvious in use effect and capable of being widely applied to design of fuel and slide oil radiator structures and ensures normal use of an engine and flying safety.

The structure is relatively complicated, which increases the volume and quality of the entire engine. In addition, sometimes due to the large amount of impurities in the fuel oil, the radiator will be accidentally blocked, causing the oil passage to be blocked or even completely blocked. , so that the engine cannot work normally, and even lead to accidents. Contents of the invention [0003] The purpose of the present invention is to design a structure that is...
