Problems solved by technology

The cooling water flow in the traditional external cooling water jacket has no direction and regularity, and it is easy to form a flow dead zone and reduce the heat dissipation efficiency; the temperature of the cooling water flow increases gradually along the flow process, and the cooling effect of the lower part is relatively poor; both situations are very It is easy to cause uneven cooling of the barrel and cause the barrel to bend

Abstract

The invention provides a spiral turbulent-flow blade based emitting device barrel cooling water jacket. The spiral turbulent-flow blade based emitting device barrel cooling water jacket comprises a water jacket body, a water inlet and a water outlet, wherein the water jacket body is barrel-shaped, and sleeves a emitting device barrel; the water inlet and the water outlet are separately positionedin upper and lower wall surfaces of the two ends of the water jacket body; and the inner wall of the water jacket body is equipped with a spiral water conveying blade in the peripheral direction fromthe front end to the rear. The spiral turbulent-flow blade based emitting device barrel cooling water jacket can perform efficient cooling on the barrel in a continuous shooting process of the emitting device.

Description

technical field [0001] The invention relates to a cooling technology for a launching device, in particular to a cooling water jacket for a barrel of a launching device based on spiral spoiler blades. Background technique [0002] During the continuous shooting of the launching device, the temperature of the barrel continues to rise, which seriously threatens the safety of the propellant and the service life of the barrel. Many launchers use external cooling to reduce barrel temperature. The cooling water flow in the traditional external cooling water jacket has no direction and regularity, and it is easy to form a flow dead zone and reduce the heat dissipation efficiency; the temperature of the cooling water flow increases gradually along the flow process, and the cooling effect of the lower part is relatively poor; both situations are very It is easy to cause uneven cooling of the barrel, causing the barrel to bend. Contents of the invention [0003] The object of the p...
