Blast deflector

Abstract

The invention discloses a blast deflector. The blast deflector comprises a thermal diffusion layer, a structure layer and a cooling layer, wherein the thermal diffusion layer comprises one or more thermal diffusion modules; each thermal diffusion module comprises a closed circuit pulsating heat pipe and solid-liquid phase transformation materials; the structure layer adopts a lattice sandwich structure, and comprises an upper panel, a lower panel, basic cells and solid-liquid phase transformation materials; the cooling layer comprises a seawater cooling plate and a seawater transporting pump;the seawater cooling plate comprises a water inlet, a water outlet, a water diversion tank, a water collecting tank and a honeycomb type fractal flow channel network; the closed circuit pulsating heatpipes are arranged on the thermal diffusion layer in a module manner; when the center of the surface of the blast deflector is impacted by fuel gas, the characteristics that when any part of the closed circuit pulsating heat pipe is heated, the heat transfer characteristics are hardly changed, the thermal responding speed is high and the heat transfer capacity is excellent are utilized, the solid-liquid phase transformation materials stuffed in the space of a non-closed circuit pulsating heat pipe on the thermal diffusion layer and a non-basic-cell space on the structure layer are used for absorbing and storing massive melting heat in a phase transformation manner, so that heat quantity on the thermal diffusion layer is rapidly diffused, and good soaking performance is realized.

Description

technical field [0001] The invention relates to a deflector, in particular to a deflector which utilizes a combination of a closed-loop pulsating heat pipe and a solid-liquid phase change material to realize thermal diffusion and uses flowing seawater to cool through a honeycomb fractal channel network. Background technique [0002] The jet deflector is a key equipment necessary to ensure the safe and continuous take-off of the carrier-based aircraft on the aircraft carrier. Its function is to deflect the high-temperature and high-speed gas injected by the jet engine when the carrier-based aircraft is ready to take off. Optimizing the design of the deflector is an important measure to protect the personnel, equipment and other aircraft on the rear flight deck of the carrier-based aircraft and improve its heat transfer efficiency to save energy and reduce emissions. [0003] Since the take-off interval of the aircraft on the carrier is very short, and the temperature of the s...

AI Technical Summary

Problems solved by technology

Most of the deflectors currently used mainly rely on the heat conduction of metal materials to transfer heat. Limited by the thermal conductivity of the material itself, they often have the characteristics of slow heat dissipation, easy damage to the plate, and short service life. This not only increases the cost of the deflector, but also Decrease the combat capability of the aircraft carrier
