A deflector device for high temperature gas

Abstract

The invention discloses a guide plate device used for high-temperature fuel gas. The guide plate device comprises a guide plate and an outer circulation heat exchange system. The guide plate comprises a guide plate body, an atomization phase change chamber and a liquid chamber. The atomization phase change chamber is located between the guide plate body and the liquid chamber. The liquid chamber is provided with a nozzle and an ultrasonic generator, wherein the nozzle sprays liquid in the liquid chamber out and conducts primary atomization in the atomization phase change chamber, and the ultrasonic generator is used for conducting secondary atomization on liquid drops obtained after primary atomization. The atomization phase change chamber is used for gasifying the atomized liquid drops under the condition that the guide plate body is subjected to the effect of the high temperature. The outer circulation heat exchange system comprises a heat exchanger and a liquid conveying pump. A gas inlet of the heat exchanger is connected with a gas outlet, and a cooling water outlet of the heat exchanger is connected with the liquid chamber through the liquid conveying pump. Compared with the prior art, the change processes that liquid is atomized into the liquid drops and the liquid drops absorb heat to be gasified are utilized, the fuel gas guide plate is rapidly and continuously cooled.

Description

technical field [0001] The invention relates to a gas deflector, in particular to a gas deflector which uses boiling phase change heat transfer technology to efficiently dissipate heat. Background technique [0002] my country is a large country with nearly 3 million square kilometers of oceanic territory. How to maintain our country's territorial waters and maritime rights and interests has become an urgent problem for us to solve. Aircraft carriers, as an indispensable weapon for the modern navy to seize large-scale sea and air control, have important strategic significance for my country's coastal defense. Fighter planes are one of the important combat weapons of aircraft carriers. In recent decades, with the gradual improvement of combat requirements, fighter planes carry more and more weapons, their take-off weights are getting heavier, and their required take-off speeds are also increasing. High, a take-off method that can make fighter jets reach the required take-off...

Problems solved by technology

At present, there are two main cooling methods used by the gas deflector. One is mainly relying on the heat conduction of metal materials, but due to the limitation of the heat conduction capacity of the material itself, it is often impossible to dissipate heat in time, which makes the plate often in a high temperature state. It is very easy to burn, which greatly reduces the service life of the gas deflector, increases the maintenance cost of the aircraft carrier, and reduces the combat effectiveness of the aircraft carrier; another cooling method is liquid cooling, which is cooled by a number of seawater installed on the lower surface Cooling is achieved by pipe convection heat exchange to achieve the safe working temperature range of the gas deflector, and the cooling water temperature is controlled not to exceed 100°C by adjusting the flow of cooling sea water

But even with forced convection, the convective heat transfer coefficient of seawater is only 1000~1500W / m 2. K
