The specific embodiment
Below in conjunction with accompanying drawing and through specific embodiment the utility model is done further to detail, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
A kind of engine cooling passage comprises unmanned aerial vehicle body 1 and cooling-gallery, on unmanned aerial vehicle body, is shaped on the cooling-gallery that is communicated with driving engine 6, and the innovative point of the utility model is:
Said cooling-gallery comprises ventilation inlet 4, passage 5 and exhaust outlet 3; The ventilation inlet of cooling-gallery built in the head position of front fuselage and opening forward; The exhaust outlet of cooling-gallery on the fuselage of wing 2 tops and opening upwards; Ventilation inlet communicates through the passage in fuselage with exhaust outlet, and this heat dissipation channel is communicated with the driving engine that is installed in the fuselage.
In order to help quickening air current flow and reduce flight resistance more, the inside face of said passage is made as smooth cambered surface.
In order to guarantee better thermal diffusivity, said cooling-gallery is two and the fuselage both sides of symmetry above wing.
The utility model principle of work be:
In the unmanned plane during flying process; Air gets into cooling-gallery by the ventilation inlet in fuselage the place ahead; Discharge via exhaust outlet through driving engine and the heat that carries engine producing, and utilize " siphonic effect " of air to strengthen the heat radiation of air current flow boost engine, quicken substracted heat.
