Integrated active heat dissipation device used for undercarriage shock absorber

Abstract

The invention discloses an integrated active heat dissipation device used for an undercarriage shock absorber. The integrated active heat dissipation device comprises a heat dissipation medium storage tank, a heat dissipation medium pump body, an annular heat dissipation medium injection pipe assembly, an infrared temperature sensor and a battery. The heat dissipation medium storage tank is detachably mounted on the outer wall of the top of the undercarriage shock absorber. An inlet of the heat dissipation medium pump body is connected with a medium outlet of the heat dissipation medium storage tank, an outlet of the heat dissipation medium pump body is fixed to one end of a guide pipe, a temperature control switch electrically connected with an airborne avionics system is arranged on the heat dissipation medium pump body, and the temperature control switch is electrically connected with the heat dissipation medium pump body. The annular heat dissipation medium injection pipe assembly is fixed to the undercarriage shock absorber in a sleeving manner and is connected with the other end of the guide pipe. The infrared temperature sensor is electrically connected with the airborne avionics system and is fixed to the annular heat dissipation medium injection pipe assembly. The battery is detachably mounted on the heat dissipation medium storage tank. By means of the device, the problems that when an aircraft lands, the temperature of the shock absorber is too high and the working performance is greatly reduced can be solved to a certain degree, the safety of aircraft landing is improved, and the device is simple and compact in structure, convenient to use and easy to manufacture and produce.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of landing gear shock absorbers, and more specifically relates to an integrated active heat dissipation device for landing gear shock absorbers. Background technique [0002] When the aircraft lands, the landing gear bears a huge impact, and the shock absorbing device provides a strong guarantee for the smooth movement of the fuselage as a whole. The traditional oil-gas shock absorber uses the back and forth flow of the oil through the piston hole and the compressibility of the gas to form a damping force to reduce the external impact, but it is also accompanied by severe heat generation. In some special cases, some large carrier aircraft even take off and land in places with poor road conditions, which further aggravates the heat generation of the shock absorber. If the heat dissipation problem cannot be solved, the damping of the shock absorber will attenuate accordingly, which will af...
