Phase change heat buffer type shipboard flame baffle

Abstract

The invention discloses a phase change heat buffer type shipboard flame baffle which is composed of a heat dissipation structure layer and a heat exchange layer. The heat dissipation structure layer is composed of heat conduction plates, heat equalizing fins and a phase change material, a heat dissipation cavity is formed between the upper heat conduction plate and the lower heat conduction plate,the heat equalizing fins are arranged in the heat dissipation cavity, and the phase change material is filled between the heat equalizing fins of the heat dissipation cavity; the heat exchange layeris positioned below the heat dissipation structure layer and is attached to the heat dissipation structure layer; the heat equalizing fins comprise central heating bodies and heat dissipation branchesuniformly distributed in the circumferential direction of the central heating bodies; and the heat dissipation branches comprise a main branch and sub branches arranged at intervals on the main branch. According to the phase change heat buffer type shipboard flame baffle, the excellent heat conduction performance of foam metal and the fins is utilized, so that the shipboard flame baffle has moreefficient heat absorption and heat dissipation capabilities; and meanwhile, the high heat storage capability of the composite phase change material is combined, so that the safety of the system is effectively improved, the service life of the shipboard flame baffle is prolonged, and the maintenance difficulty of an aircraft carrier is reduced.

Description

technical field [0001] The invention relates to a flame shield in the aviation field, in particular to a flame shield with a snowflake-shaped fin structure and filled with composite phase-change materials between the ribs, which is designed to improve heat exchange performance and safety, and prolong service life. Thermal buffer flame deflector. Background technique [0002] With the continuous development of military technology, the aircraft carrier has become one of the most powerful weapons in the world and a symbol of a country's comprehensive national strength. The main attack power of the aircraft carrier is reflected in the carrier-based aircraft, but the take-off and landing of the carrier-based aircraft is difficult. High risk. Before the carrier-based aircraft takes off, the engine goes through three states: idle state, transition state and full afterburner state. When the engine is in the state of full afterburner, the speed of the gas flow at the tail nozzle ca...
